Abstract

Burden of diseases attributable to low physical activity is increasing worldwide mainly among working age populations. The aim of the study was to evaluate the association between selected (including demographic and socioeconomic) factors and leisure-time physical activity. The study was performed in the randomly selected group of 450 men and 502 women in the working age. Logistic regression models were applied to assess factors related to physical activity limitations. Physical activity was determined by the physical activity questionnaire. Over 55% of the study participants were inactive, 34.1% were insufficiently active, and only 10.6% of the subjects achieved the level of physical activity recommended by experts in health promotion. Significant differences in physical activity behaviors across age, education, income levels, and marital status were found in the study participants. Unhealthy weight and smoking habit also formed certain barriers to exercise in both men and women. Low number of physically active working-age citizens is a challenge for public health, and it confirms the need for promoting active lifestyles. Effective strategies to encourage leisure-time physical need to be targeted at specific age and socioeconomic groups.

Objectives: Burden of diseases attributable to low physical activity is increasing worldwide mainly among working
age populations. The aim of the study was to evaluate the association between selected (including demographic and
socioeconomic) factors and leisure-time physical activity. Materials and Methods: The study was performed in the randomly
selected group of 450 men and 502 women in the working age. Logistic regression models were applied to assess factors

Over 55% of the study participants were inactive, 34.1% were insuf ciently active, and only 10.6% of the subjects achieved
the level of physical activity recommended by experts in health promotion. Signi cant differences in physical activity
behaviors across age, education, income levels, and marital status were found in the study participants. Unhealthy weight
and smoking habit also formed certain barriers to exercise in both men and women. Conclusions: Low number of physically
active working-age citizens is a challenge for public health, and it con rms the need for promoting active lifestyles. Effective

INTRODUCTION
Rapid changes in lifestyles, including physical activity and
diets, associated with the progress of industrialization, ur-
banization, and economic development, have accelerated
over the past decade, making a signi cant impact on the
health status of populations, particularly in the develop-
ing countries and countries in transition. While standards
of living have improved and access to new medical tech-
nologies has increased, signi cant negative consequences
in terms of decreased physical activities, inappropriate
dietary patterns, and a corresponding increase in chronic
diseases, especially among poor people have also emerged
[1,2]. Because of these changes, chronic diseases, includ-
ing cardiovascular diseases (CVD), obesity, diabetes mel-
litus, and some types of cancer are becoming increasingly
signi cant causes of disability and premature death, plac-
ing additional burdens on already overburdened national
health budgets.
Indirect costs of diseases attributable to low physical activ-
ity are also very high among people in the working-age and
are associated with work days lost, physician visits, disabil-
ity pensions, and lowered work ability [3,4]. Physical activ-
ity is one of the most important modi able determinant of
chronic diseases. There is convincing evidence that regu-
lar physical activity is protective against unhealthy weight
gain whereas sedentary lifestyles, particularly sedentary
occupations and inactive recreation (e.g., watching tele-
vision), promote this ailment. For health promotion and

chronic disease prevention practicing an endurance activ-
ity at moderate or higher level of intensity for one hour or
more per day on most days of the week is recommended.
According to the European Guidelines on CVD Preven-
tion in Clinical Practice endurance training with moder-
ate intensity (60–75% of max heart rate) undertaken at
least 4–5 times a week for 30–45 min is required. Energy
expenditure on exertion should exceed 1000 kcal/week
[5]. A higher volume or intensity of activity would confer
a larger protective effect.
Regardless of the established health bene ts resulting
from regular leisure-time physical activity, currently a ma-
jority of the world population, including Poles, do not take
up physical exercises at a suf cient level, or any training at
all [6]. The currently available scienti c evidence indicates
numerous factors that can negatively in uence the level
of leisure-time physical activity [7,8]. Such factors include
a complex combination of interacting socioeconomic, cul-
tural, and other environmental parameters. Recognizing
the factors affecting participation in physical activity is
a rst step that may
help to develop
effective preventive
programs.
The aim of the study was to evaluate association between
selected (including socioeconomic or demographic) fac-
tors and leisure-time physical activity among men and
women in the working age.
MATERIALS AND METHODS
The study was performed in the population of adults ran-
domly selected by the Local Data Bank in Łódź, which
rendered the data available with the proportional draw
scheme. As an operator the personal identi cation num-
ber (in Polish PESEL) was used. Of the directly drawn
2000 persons, 954 answered all the questions included in
the questionnaire. Physical activity was determined by the
physical activity questionnaire based on the Country Wide
Noncomunicable Disease Intervention Program, World
Health Organization (CINDI, WHO) health monitoring
questionnaires [9]. The questionnaire sought information
concerning leisure-time physical activity (LTPA). In the
assessment of LTPA, people were asked whether they reg-
ularly practiced any physical exercises (walking, jogging,
cycling, swimming, gymnastics) for at least 30 min. More-
over, those who did were asked to recall the frequency
of such activities. Satisfactory level of LTPA (compliance
with physical activity guidelines) was de ned as practicing
exercises on most days of the week, insuf cient LTPA was
de ned as being active less than twice a week. Individuals
who had declared lack of physical activity, practicing any
physical exercises were classi ed as inactive. Three groups
of television watching were also de ned on the basis of
the distribution of the time spent watching television in
our sample: less than 1 h/day, 1 to 3 h/day, and 3 h/day.
While interviewing the subjects, the data on education, in-
come, marital status and smoking were also collected.
Statistical analysis
For the statistical analysis of the measurable character-
istics, their range (minimum–maximum), mean values
(arithmetic mean and median), and also standard devia-
tion were calculated. To compare the frequency of the
given categories of quantitative characteristics in the
analyzed groups the Chi
2
test or the Chi
2
test with Yates’
correction were implemented. The distribution of measur-
able characteristics was analyzed using the Shapiro-Wilk
test. A level of signi cance was established at p = 0.05 for
the values included in the critical region of a given distri-
bution. The Chi
2
test was used to determine differences in
activity by selected characteristics, including age, educa-
tion, employment status, level of monthly income, marital
status, body mass index (BMI), smoking, and television
watching. In addition, to identify risk factors that can con-
tribute to lack of leisure-time physical activity, the logistic
regression analysis was performed. At the rst stage, crude
coef cients — odds ratios (OR) of the impact of singular
variables on the risk of lack of recreational physical activ-
ity in men and women were calculated. Subsequently, the
multifactorial analysis, considering simultaneous effect
of all variables on the risk of lack of leisure-time physical
activity in the study subjects, was employed. All p values
were two-sided and p < 0.05 was set as statistically sig-
ni cant. The statistical analysis was performed with the
STATGRAPHICS plus 5.1 program.

RESULTS
Based on the information collected during interviews, the
subjects were characterized by means of basic anthropo-
metric indices and selected socio-economic variables (Ta-
bles 1 and 2). In Tables 1 and 2, the subjects are categorized
as inactive, insuf ciently active and achieving satisfactory
level of physical activity. Over 55% of study participants
(including 52.9% of men and 57.6% of women) were inac-
tive, 34.1% (including 34.6% of men and 33.7% of women)
were insuf ciently active and only 10.6% (including 12.6%
of men and 8.8% of women) of the subjects achieved the

the subjects. The risk of lack of leisure-time physical activ-
ity in men and women was signi cantly associated with age
(Table 3). Among men aged 55–64 years, the risk for inac-
tivity was about 2-fold higher than in men aged 25–34 years
(adjusted OR = 1.95; 95% CI: 1.14–3.32). Among women
the highest risk of inactivity was in those aged 45–54 years
(adjusted OR = 2.89; 95% CI: 1.52–3.51). In the women
aged between 55–64 years, the risk of lack of activity was
over 2-fold higher than in those aged under 34 years (ad-
justed OR = 2.51; 95% CI: 2.43–4.35). In both genders,

the level of education was signi cantly associated with the
level of leisure-time physical activity (Table 3). In men with
primary education, the risk of inactivity was over 3 times
higher than in men with university education (adjusted
OR = 3.27; 95% CI: 1.16–5.47). Among women with pri-
mary education, the risk of sedentary behavior was over
4 times higher than in women with university education
(adjusted OR = 4.23; 95% CI: 4.14–0.39). No correlation
between the employment status and participation in recre-
ation activities was found. Statistically signi cant associa-
tion between the economic status and the level of leisure-
time physical activity was found only in women (Table 3).
In the group of women with the lowest monthly income
per person in family, the risk of inactivity was higher than
in women with monthly income higher than 250 euros (ad-
justed OR = 1.65; 95% CI: 1.57–9.40). Furthermore, lei-
sure-time physical activity in women was associated with
marital status. Among married women, the risk of lack of
physical activity was over two times higher than in single
women (adjusted OR = 2.16; 95% CI: 1.10–3.83).
The lack of leisure-time physical activity in the study
subjects was also associated with body mass index. In the
group of obese men risk of inactivity was almost 2 times
higher than in men with healthy weight (adjusted OR =
=1.91; 95% CI: 1.21–3.61). In the group of obese women
the risk of sedentary behaviors during leisure was over
twice higher than in women with BMI 25 (kg/m
2
) (ad-
justed OR = 2.27; 95% CI: 1.26–1.07).
In both groups, leisure-time physical activity was found
to be associated with smoking habit (Table 3). In men
who were current smokers, the risk of inactivity was sig-
ni cantly higher than in men who never smoked (adjusted
OR = 1.79; 95% CI: 1.02–3.14). In currently smoking
women, the risk of sedentary behavior was nearly 2 times
higher in comparison with never smoking women (adjust-
ed OR = 1.66; 95% CI: 1.12–2.71). Moreover, in women
who had declared television watching longer than 3 h/day,
the risk of not taking up leisure-time physical activity was
almost 3 times higher than in women who watched TV less
than 1 h/day (adjusted OR = 2.89; 95% CI: 1.52–3.5). In
men, no association was found between time spent
watch-
ing television and inactivity (Table 3).
DISCUSSION
In Poland,
there are very few data concerning the level of
physical
activity compared with other Western European
countries and the United States. In our study, over 55%
of the study participants were inactive and only 20.7%
of the men and 10.9%
of the women achieved recom-
mended levels of physical activity.
These rates also appear
quite different from those reported in West Europe and
the United States [10–13]. In a recent French study, for
example, recommended
levels of physical activity were
achieved by 62% of men and
52% of women, whereas
10% of men and 12% of women reported no
physical ac-
tivity at all in their leisure [14]. Similar gures
were also
reported in U.S. studies [8,12]. In a study carried out by
Jones et al. [11], 32% of adults
were engaged in moder-
ate LTPA at least 10 times over a 2-week period
for a to-
tal duration of 30 min or more. The level of leisure-time
physical activity in Poland is comparable with that in the
Baltic countries. The data from three national surveys of
adults conducted in Estonia, Latvia, and Lithuania showed
that one in three Estonians and one in ve Latvians and
Lithuanians had a low physical activity level at work [15].
Furthermore, half of the respondents participated only in
sedentary activities during their leisure time. According to
our data, in the Baltic countries leisure-time inactivity was
inversely related to the education level in men and women
and to income in men. Our results show healthier physical
activity patterns in subjects younger than 45 years of age,
as
recently con rmed by the Behavioral Risk Factor Surveil-
lance System data [13]. Macera et al.[12] have
also shown
that the percentage of subjects meeting the recommended
physical activity levels were higher in younger than in oth-
er age groups (18–29
years vs. 30–64 years). Other studies
con rm as well a negative relationship between age and
recreational physical activity level [16].
Several studies have shown that LTPA performance can be
related to educational
level.
Signi cant
associations were
documented by Jones et al. [11] in a study carried out un-
der the Behavioral Risk Factor Surveillance
System and
the National Physical Activity Surveys in Australia [8,13,
17,18]. It is suggested that higher education may increase

awareness of the bene ts of healthy behaviors, including
exercise, and improve individuals’ ability to follow health
education messages. In our sample, the compliance with
the peak heart rate (PHR) for physical
activity was related
to educational level and this relationship
was statistically
signi cant after multivariate adjustment. Furthermore,
statistically signi cant association between the economic
status and LTPA level was found in women. This relation-
ship was not statistically signi cant among the men, but
the trend of alterations remained. Possible explanations
for socioeconomic differences in taking-up physical ac-
tivity during leisure involve differences between socio-
economic groups in health-related knowledge, behavior,
values, and attitudes as well as in economic barriers
to
exercise. Moreover, according to Parks et al. [18] lower
income residents
were more likely than others to report
poor health or fear of injury as barriers to physical activ-
ity.
Evidence
for a dose-response relation emerged among
these personal barriers
as well. For all urban residents
each additional barrier reported
resulted in an incremen-
tal decrease in the likelihood of meeting
physical activity
recommendations.
Our results showed healthier physical
activity patterns in
single than in married women. It is possible that married
women are overburdened with high level of occupational
or household-related physical activities. Adults who expe-
rience a larger number of personal barriers, such
as lack of
time, work fatigue or lack of energy are known to be less
active [7,18].
Our study showed that obese people were less likely to be
active during leisure than those with healthy weight. These
results are consistent with the majority of data yielded by
studies of the relation between LTPA and obesity. Longi-
tudinal study of Petersen et al. [19] indicates that obesity
may cause some limitations and lead to physical inactivity.
According to this ndings, the inverse cross-sectional re-
lation may be due to the reduction of physical activity as
a consequence of obesity, assuming that the worse discom-
fort of physical activity the greater the overweight. In our
study, we failed to determine which obesity or inactivity
is the cause and which is the effect. Our study results are
rather limited and cannot solve this problem, but the level
of leisure-time physical activity plays an important role in
energy balance.
Negative association was found
between leisure-time
physical activity and smoking in both men and women. It
is well known that health risk behaviors, such as smoking,
insuf cient
levels of physical activity, improper diet, have
a tendency to cluster, especially among people with lower
education as also observed in the present study [18]. An-
other possibility for this nding is that in smokers, various
health limitations (as a consequence of smoking) to exer-
cise may occur.
We also found
that LTPA level was related to time spent
watching television in women.
This association was not
statistically signi cant in men but the trend of alterations
remained. Several studies have revealed independent as-
sociations
between LTPA, television watching and health
outcomes, such as
obesity and other cardiovascular risk
factors [20–22]. These
ndings suggest that public health
policies should encourage
both an increase in physical ac-
tivity and a decrease in sedentary
occupations, especially,
time spent on TV watching [14]. Furthermore, interven-
tion studies evidence that a reduction in TV and video-
tape watching, and playing video
games can be effective
in children to encourage LTPA and limit body weight
gain
over time [23].
Low number of physically active working-age citizens is
a challenge for public health in Poland, and it con rms
the need for promoting active lifestyles. Effective strate-
gies to encourage leisure-time physical activity need to be
targeted at speci c age and socio-economic groups.
CONCLUSIONS
1. The results of the present study reveal that over 80% of
men and women in the working-age do not meet recom-
mendations for leisure-time physical activity.
2. Signi cant
differences in physical activity behaviors
across age, education, income levels or marital status
were
found in the study participants.
3. Certain barriers
to exercise in men and women also in-
cluded unhealthy weight and smoking habit.

Esta revisão sistemática tem como objetivo analisar a relação entre os níveis de prática de atividades físicas e as condições sociais. Foi realizada uma busca na base de dados Pubmed e Scielo até Maio de 2015, utilizando as palavras chaves: physical activity, physical exercise, sedentary lifestyle, sedentay behaviour, socioeconomic status e socioeconomic factors. Os artigos foram analisados utilizando os critérios de inclusão: a) mostrar de forma explícita que investigavam tais associações; b) amostra com idade superior a 18 anos; c) redigidos em língua inglesa e portuguesa; d) data de publicação a partir do ano 2005. Foram adotados os seguintes critérios de exclusão: a) artigos que investigavam tais associações, mas envolviam outras síndromes e/ou doenças; b) estudos de revisão. Foram utilizados os parâmetros do Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) composto por uma lista de verificação de 22 itens a fim de analisar a qualidade dos estudos. Foram identificados 573 artigos. Após análise integral, restaram 43 artigos para a revisão. Esta revisão identifica que os indivíduos de menor escolaridade e renda, com pior qualificação profissional estão sujeitos a prática insuficiente de atividade física no lazer e por sua vez a uma maior sobrecarga ocupacional e de deslocamento.
... Only partial results are obtained by contrasting age groups. Compared to the youngest age group (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29), the middle-agers are more prone to low PA by 70% (30)(31)(32)(33)(34)(35)(36)(37)(38)(39) and 80% (40)(41)(42)(43)(44)(45)(46)(47)(48)(49). A similar proportion holds for individuals in their 50s, 60s and older; however, the significance is only slightly above the 0.05 threshold. ...
... In this context, the socioeconomic status, which has been strongly confirmed in the modeling procedure, is even more distinctive. Higher education, high professional status and related incomes go together with the share of the sufficiently active and the duration of LTPA [48,49]. High SES is associated with caring for one's own health, while a professional career demands good fitness, stress resilience, and a slim figure [50,51]. ...

Background: Insufficient physical activity (PA) has become an increasing risk factor of noncommunicable diseases and an important cause of deaths all over the world. The goal of this paper is to provide an in-depth description of insufficient PA in Poland as well as an examination of some of its correlates. Methods: We take advantage of statistical and econometric (logistic regression) analysis on the basis of a representative survey. Out of 3056 respondents, we analyze the 1260 low-PA ones. Results: The household size is more significant than the household life phase, and only several professions increase the odds of insufficient PA. The influence of socioeconomic status and place of residence is most robust. Gender does not significantly influence insufficient PA. Physical inactivity is concentrated among inhabitants of rural areas and town dwellers, with poor educational profile, and limited labor market opportunities. However, even high socioeconomic status does not completely prevent insufficient activity. Conclusions: Groups at the highest risk of inactivity should be covered by promotional actions first. Their aim should mainly be raising the leisure-time physical activity (LTPA) awareness. To start with, primary forms of activity would be walking, Nordic walking and jogging.
... Historically, literature identified that workers of lower occupational status or blue-collar workers participate in less leisure-time physical activity and are more likely to be insufficiently active to maintain health than professional and whitecollar workers (11,46,49,52,58). The higher the level of education, professional status and income connected to it, the longer the LTPA participation time (26) and the smaller the percentage of people with a low level of physical activity (27). Previous studies also showed that in sedentary occupations leisure-time included more physical activity than work-time (38,53). ...

Background: Extending working lives has become an inevitable objective of public policy in the era of population ageing. It is possible, however, that the duration of working life will depend on individual employability. Out of a wide range of factors affecting employability, we have undertaken in this paper to analyze one specific aspect of health status, which is physical activity. Objectives and methods: This paper studies the relationship between physical activity and BMI among representatives of 7 occupational groups in Poland using a logit regression. We use a dedicated micro-database of over 5,000 Warsaw inhabitants. Results: Being overweight and obese is a significant problem among scientific researchers and public administration professionals; however, insufficient physical activity mainly affects sales workers and health professionals. Sex and age groups and professions are a far better predictor of a high BMI than the level of individual physical activity. In the case of the latter, the number of recreational disciplines and frequency of walking is more important than any other physical activity-related variable. We confirm the intuition that being overweight and having a sedentary lifestyle lead to a vicious circle of inactivity. Conclusions: In order to break this cycle or at least bring it under control, it is necessary to monitor the weight and waist circumference of workers, which is a prerequisite for any further intervention.

... Thereby, reduced insulin sensitivity may inflate the perception of effort (McArdle et al., 2010). These results corroborate a wealth of evidence indicating that BMI is positively associated with an increased fraction of time spent on sedentary activities, which require little physical activity (eg, watching TV) in everyday life (Beunza et al., 2007;Kaleta and Jegier, 2007;Matthews et al., 2008;Mitchell et al., 2013;Rhodes et al., 2012). In line with these results, in obese women, eating away from home and consumption of instant meals (vs self-prepared food) is associated with increased impulsivity and excess caloric intake (Appelhans et al., 2012) suggesting that the perceived effort to prepare food may contribute to the maintenance of unhealthy diets. ...

By definition, instrumental actions are performed in order to obtain certain goals. Nevertheless, the attainment of goals typically implies obstacles, and response vigor is known to reflect an integration of subjective benefit and cost. Whereas several brain regions have been associated with cost/benefit ratio decision-making, trial-by-trial fluctuations in motivation are not well understood. We review recent evidence supporting the motivational implications of signal fluctuations in the mesocorticolimbic system. As an extension of “set-point” theories of instrumental action, we propose that response vigor is determined by a rapid integration of brain signals that reflect value and cost on a trial-by-trial basis giving rise to an online estimate of utility. Critically, we posit that fluctuations in key nodes of the network can predict deviations in response vigor and that variability in instrumental behavior can be accounted for by models devised from optimal control theory, which incorporate the effortful control of noise. Notwithstanding, the post hoc analysis of signaling dynamics has caveats that can effectively be addressed in future research with the help of two novel fMRI imaging techniques. First, adaptive fMRI paradigms can be used to establish a time–order relationship, which is a prerequisite for causality, by using observed signal fluctuations as triggers for stimulus presentation. Second, real-time fMRI neurofeedback can be employed to induce predefined brain states that may facilitate benefit or cost aspects of instrumental actions. Ultimately, understanding temporal dynamics in brain networks subserving response vigor holds the promise for targeted interventions that could help to readjust the motivational balance of behavior.
... This fact suggests that it may exist an economic relationship between these variables 18,19 . This hypothesis is strengthened once the direct relationship between physical inactivity and the lowest economic and education strata are observed 5,20 . ...

El objetivo fue analizar los factores asociados a la inactividad fisica en personas mayores en Brasil. Se utilizo un diseno transversal, con una muestra representativa de 909 sujetos de 60 anos o mas. Fueron clasificados como fisicamente inactivos los individuos con menos de 150 minutos de actividad fisica semanal. La identificacion de los factores sociodemograficos, aspectos comportamentales y de salud asociados con la inactividad fisica se realizo con un analisis multivariante a traves de una regresion de Poisson. Los resultados sugieren una prevalencia del 39,1% para la inactividad fisica. La inactividad fisica presenta una mayor prevalente con o el incremento de la edad, la falta de practica de actividad fisica regular en el pasado, los sintomas de depresion y la discapacidad en las Actividades Instrumentales de la Vida Diaria. El aumento de la edad, la falta de practica regular de actividad fisica en el pasado, los sintomas depresivos y la discapacidad en las Actividades Instrumentales de la Vida Diaria se evidencian como factores asociados a la inactividad fisica. PALABRAS CLAVE: actividad fisica, salud, personas mayores, Brasil. ABSTRACT The aim was to analyse factors associated with physical inactivity in elderly Brazilians. The study was carried out by using a cross-sectional design and it comprised a representative sample of 909 subjects. Physical inactivity was defined as fewer than 150 minutes per week.

Physical activity and obesity are known to be associated. We investigated whether a change in leisure time physical activities (LTPA) predicts a subsequent weight change, or vice versa. We used data from a longitudinal study among Danish adults surveyed in 1983–1984, 1987–1988, and 1993–1994. Between two sequential surveys, the change in LTPA was grouped as no change, became less or more active; the change in body weight was defined as no change, lost or gained of more than one body mass index (BMI) unit. Among 2386 adults, change in LTPA was not associated with subsequent weight change. However, a loss in body weight (BMI change < −1 unit) was associated with subsequent either becoming less [OR = 1.49, 95% CI (1.03–2.15)] or borderline more active [OR = 1.37, 95% CI (0.99–1.90)]. Subgroup analyses showed particularity among females that a loss in body weight was associated with subsequent becoming more active [OR = 1.83, 95% CI (1.15–2.89)]. Our results suggest that change in LTPA is unrelated to subsequent weight change, but loss in body weight seems related to subsequent more active among female adults.

Rising life expectancy of the populations living in highly developed countries has been observed over recent decades. The number of people worldwide above the age of 60 is increasing at an unprecedented pace. The purpose of the study was to determine the significance of physical activity of older people in the process of successful ageing. Research methods. This article is a review of Polish and foreign studies considering the relationship between physical activity and successful ageing. The elaboration refers to the results of surveys published in the reviewed scientific journals including empirical studies mainly based on diagnostic survey. Study results. A thorough analysis identified three parts: the concept of successful ageing, the relationship between physical activity and health, and physical activity of older persons in Poland compared to their counterparts abroad. A review of the literature and documents has revealed that one of the main factors affecting successful ageing is physical activity. Conclusions. Physical activity and successful ageing are different in the assessed communities. Thus, it is necessary to monitor physical activity of older people in the context of successful ageing – in order to provide conducive circumstances to activating this social group and thus reducing social security cost.

Background: The aim of this work is to estimate leisure-time physical activity (LTPA) of the professionally-active population as a factor in early preventive medicine and diagnosing threats of occupational diseases. It was the basis for an analysis of the realisation of a pro-health dose of physical activity recommended by WHO (depending on the profession). Objective and methods: A survey based on IPAQ-LV was realised in 2014-2015 on a representative sample of Poles (n = 2039). The work presents results for professionally-active people (n = 985). In order to verify statistically significant differences a Chi2, U-Mann Whitney and Kruskall-Wallis H tests were implemented. Results: LTPA Index for the whole group was 895.6±1514.3 MET-minutes/week. No statistical relationship was found between the survey wave and the LTPA factor and particular activities: VPA, MPA and walking. The LTPA value was significantly related (Chi2 = 19.9; p < 0.001) to the profession. LTPA Index was highest among the higher social stratification groups (directors/managers/owners: 1492.7±2348.1, higher level office workers: 957.6±1268.3, other office workers: 973.0±1677.5 MET-minutes/week) and the lowest among skilled workers (744.8±1325.8 MET-minutes/week). As many as 61.1% of respondents did not meet WHO recommendations. During week days, the greatest time spent sitting (Chi2 = 0.000; p < 0.05) was stated for higher level office workers (6.4±4.2 hours/day) and directors/managers/owners (5.0±4.0 hours/day). Sitting time for weekends was not significantly different for these groups. Conclusions: Activities promoting LTPA should be addressed to all professional groups. It is essential to inform workers (especially physical workers) about the role of properly selected physical activity (in terms of time, frequency and type) to maintain a good state of health. A model-shaping influence of the high prestige groups may be helpful in changing lifestyle.

This study examines the prevalence of physical inactivity during leisure time in a national representative sample of U.S. adults. Data were obtained from the Third National Health and Nutrition Examination Survey, conducted between 1988 and 1994. A total of 18,825 adults aged 20 yr and older participated in a home interview where information about physical activity, education, income, occupation, employment, and labor force participation was obtained. The prevalence of physical inactivity among U.S. adults was 23%, with more women (28%) than men (17%) reporting being inactive during their leisure time. Additionally, inactivity is more common among in social class such as persons who are less educated, living below the poverty line, living in households with income below 20,000 dollars, and who are retired. In every category of social class, women experienced a higher prevalence of physical inactivity than men. We conclude that social class is associated with physical inactivity and that more research is needed to better understand the effect that other social and environmental factors have on sedentary behaviors in our society.

Physical inactivity is a known risk factor for heart disease and obesity, two major health problems in the Baltic Republics. This study examined patterns of physical activity level in these countries, and correlates of leisure-time sedentary behavior. Data from three national surveys of adults conducted in Estonia, Latvia, and Lithuania in 1997 were used. Respondents who provided information on their activity level were included in this study (Estonia: n = 2,018; Latvia: n = 2,303; Lithuania: n = 2,140). One in three Estonians and one in five Latvians and Lithuanians had a low physical activity level at work. Half the respondents (Lithuania: 60%, Latvia: 52%, Estonia: 43%) participated only in sedentary activities during their leisure time. Leisure-time sedentarity was inversely related to education level in men and women and with income in men. It was also associated with smoking in men and with inadequate vegetable intake in men and women. Sedentary behavior during leisure time should be a public health issue in the Baltic Republics. Health promotion strategies aiming at increasing leisure-time physical activity level will need to target the general population, but particularly individuals from lower socioeconomic strata.

Few studies have analysed the rates and correlates of physical activity in economically and geographically diverse populations. Objectives were to examine: (1) urban-rural differences in physical activity by several demographic, geographical, environmental, and psychosocial variables, (2) patterns in environmental and policy factors across urban-rural setting and socioeconomic groups, (3) socioeconomic differences in physical activity across the same set of variables, and (4) possible correlations of these patterns with meeting of physical activity recommendations. A cross sectional study with an over sampling of lower income adults was conducted in 1999-2000. United States. 1818 United States adults. Main results: Lower income residents were less likely than higher income residents to meet physical activity recommendations. Rural residents were least likely to meet recommendations; suburban residents were most likely to meet recommendations. Suburban, higher income residents were more than twice as likely to meet recommendations than rural, lower income residents. Significant differences across income levels and urban/rural areas were found for those reporting neighbourhood streets, parks, and malls as places to exercise; fear of injury, being in poor health, or dislike as barriers to exercise and those reporting encouragement from relatives as social support for exercise. Evidence of a positive dose-response relation emerged between number of places to exercise and likelihood to meet recommendations for physical activity. Both income level and urban rural status were important predictors of adults' likelihood to meet physical activity recommendations. In addition, environmental variables vary in importance across socioeconomic status and urban-rural areas.

The majority of the population is inactive, and strategies to date for promoting regular physical activity have been limited in their effectiveness. Further research is needed to identify correlates of physical activity in different subgroups to design more efficacious interventions. This study sought to identify correlates of physical activity across men and women, urban and rural geographical locations, and four distinct age groups (18-25; 26-45; 46-59; and 60+). This study employed data from a large provincial household random sample (N = 20,606) of Canadians. Analyses were utilized to examine the amount of variance explained in self-reported physical activity by a number of demographic and/or biological, psychological, behavioral, social, and environmental variables within each subgroup. Proportion of friends who exercise, injury from past physical activity, educational level, perceived health status, and alcohol consumption were among the strongest correlates across subgroups. A number of correlates were identified as being significant across all subgroups examined. Most differences in the correlates of physical activity were found within different age groups rather than among urban and rural residents and gender.

The public health community is becoming increasingly interested in the potential contributions of school physical education to child health. School physical education is seen as an ideal site for the promotion of regular physical activity because up to 97% of elementary school children participate in some sort of physical education program. For maximal public health benefit, school physical education programs should prepare children for a lifetime of physical activity. This public health goal for physical education may require some changes in current approaches. Physical educators are challenged to collaborate with public health professionals in developing and evaluating school physical education programs that will improve the health of the nation's youth.

To investigate the effects of television (TV) viewing on children, 4876 questionnaires on viewing habits completed by Greek children with the assistance of their parents were analysed. The most important results are summarized below. The mean time spent watching TV ranged from 21–32 h per week. The age when children started watching TV correlated with their later educational achievement: good students started watching TV earlier. Bad students, however, watched more TV, as did children from urban areas, and from lower socioeconomic groups. Children from households with more than one TV (especially if it was in the child's bedroom) also watched more. Children who watched more TV were less compliant with TV restrictions and more likely to imitate TV characters. Eating while watching TV was associated with obesity only in teenagers. Most children watched TV from appropriate distances, with the lights on, and with the sound at medium volume. Conclusion This study of TV viewing habits in Greek children shows that certain patterns of watching TV may contribute to poor educational achievement, and obesity, in paediatric patients and, therefore, supports the idea of taking “televiewing histories” when treating these patients.

We identified the prevalence of adults who met the 1993 Centers for Disease Control and Prevention and the American College of Sports Medicine moderate physical activity recommendation and the 1996 Surgeon General's Report on Physical Activity and Health energy expenditure guideline for leading a moderately active lifestyle. Participants were 16,890 women and 12,272 men at least 18 years old who were asked in the 1990 National Health Interview Survey about their leisure-time physical activities. About one third of US adults met either recommendation for moderate activity; 32% met the Centers for Disease Control and Prevention and the American Association of Sports Medicine recommendation and 38% met the surgeon general's guideline. Women, ethnic minorities, adults with lower educational attainment, and older adults were least active. Public health efforts are needed to address the issues related to physical inactivity and to provide organized programs to increase moderate physical activity levels in US adults.

There is a clear public health need to measure and track physical activity behavior. Surveillance systems should be flexible enough to keep up with scientific advances in identifying dose-response relationships and in developing new assessment techniques, and new ways to assess community indicators associated with physical activity. Having a strong public health surveillance system that produces data that can be used to plan, guide, and evaluate programs is essential for increasing the prevalence of an important health-related behavior: physical activity.

The purpose of this study was to investigate the relation between perceived importance of physical activity and demographic variables and current physical activity level with specific reference to the CDC/ACSM guidelines for sufficient physical activity for a health benefit. Physical activity levels were assessed by a telephone survey of 2002 households throughout the continental United States and the District of Columbia to determine whether the individuals met the CDC/ACSM physical activity guidelines. Results indicate that 68% of the respondents are physically active below the CDC/ACSM criterion. Chi-square analysis revealed significant relationships between meeting the CDC/ACSM physical activity guidelines and 1) perceived importance of physical inactivity as a health risk (P < 0.0001), and 2) gender (P < 0.0001). Logistic regression analysis revealed that having a greater awareness of the health risks of physical inactivity improved the odds ratio (OR = 1.40, 95% CI = 1.21-1.62) of being sufficiently physically active for a health benefit by 40% (P < 0.0001) and being a male improved the odds ratio (OR = 1.45, 95% CI = 1.17-1.79) of being sufficiently physically active for a health benefit by 45% (P < 0.0006). Implications for health and physical fitness researchers and practitioners are that they need to improve awareness of life span fitness benefits and develop intervention programs based on individuals' current physical activity levels.
