ABSTRACT This study examines leisure time sedentary behavior (LTSB) and usual occupational/domestic activity (UODA) and their relationship with metabolic syndrome and individual cardiovascular disease (CVD) risk factors, independent of physical activity level.
National Health and Nutrition Examination Survey (NHANES) 2003-2006 data from men (n = 1868) and women (n = 1688) with fasting measures were classified as having metabolic syndrome by the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) definition. LTSB was determined from self-reported television viewing and computer usage. UODA was self-reported daily behavior (sitting, standing, walking, carrying loads).
LTSB >or=4 hours/day was associated with odds of having metabolic syndrome of 1.94 (95% confidence interval [CI], 1.24, 3.03) in men compared to <or=1 hour/day. LTSB >or=4 hour/day was also associated with higher odds of elevated waist circumference (1.88, CI, 1.03, 3.41), low high-density lipoprotein cholesterol (HDL-C) (1.84, CI, 1.35, 2.51), and high blood pressure (1.55, CI, 1.07, 2.24) in men. LTSB 2-3 hours/day was associated with higher odds of elevated glucose (1.32, CI, 1.00, 1.75) in men. In women, odds of metabolic syndrome were 1.54 (CI, 1.00, 2.37) with >or=4 hours/day LTSB, but LTSB was not associated with risk of the individual CVD risk factors. Higher LTSB was associated with metabolic syndrome in inactive men (1.50, CI, 1.07, 2.09), active men (1.74, CI, 1.11, 2.71), inactive women (1.69, CI, 1.24, 2.33), but not active women (1.62, CI, 0.87,3.01). UODA was not strongly associated with metabolic syndrome or CVD risk factors in either men or women.
In men, high LTSB is associated with higher odds of metabolic syndrome and individual CVD risk factors regardless of meeting physical activity recommendations. In women, high LTSB is associated with higher odds of metabolic syndrome only in those not meeting the physical activity recommendations.

    ABSTRACT: Objective. To (1) compare occupational sitting between different socio-demographic, health-related, work-related and psychosocial categories, (2) identity socio-demographic, health-related, work-related and psychosocial correlates of occupational sitting, and (3) examine the moderating effect of work-related factors in the relation between correlates and occupational sitting. Methods. Randomly-selected Australian adults completed a web-based survey assessing socio-demographic (country of birth, gender, age, education, income), health-related (general health, weight, physical activity), work-related (employment status, occupational task, occupational classification) and sedentary-specific psychosocial (social norm, social support, self-efficacy, control, advantages, disadvantage, intention) factors, and occupational sitting-time. t-tests, ANOVAs and multiple linear regression analyses were conducted (in 2013) on a sample of employees (n = 993). Results. Respondents sat on average for 3.75 (SD = 2.45) h/day during work. Investigated correlates explained 41% of the variance in occupational sitting. More occupational sitting was associated with being male, being younger, higher education and income, part-time and full-time employment, sedentary job tasks, white-collar/professional occupations, higher BMI, and perceiving more advantages of sitting less at work. Employment status and occupational classification moderated the association between control to sit less and occupational sitting. A lack of control to sit less was associated with higher occupational sitting in part-time and full-time workers, but not in casual workers; and in white-collar and professional workers, but not in blue-collar workers. Conclusions. Most important contributors to occupational sitting were work-related and socio-demographic correlates. More research is needed to confirm present results.

    ABSTRACT: Children and adolescents in developed countries are heavily immersed in digital media, creating an inexpensive, far-reaching marketing opportunity for the food industry and the gaming industry. However, exposure to nonnutritious food and beverage advertisements combined with the use of stationary media create a conflict between entertainment and public health. Using the popular digital gaming platforms advergames (online games that market branded products) and exergames (video games that involves gross motor activity for play) as exemplars, the following article provides an analysis of the negative and positive health impacts of digital gaming as they relate specifically to overweight and obesity outcomes for children and adolescents. Theoretical explanations including the food marketing defense model, persuasion knowledge model, and social cognitive theory are used to explain the influence of gaming on young players' health. Throughout the article, we discuss the role of public policy to encourage the development and use of health-promoting digital games as an innovative, effective tool to combat the pediatric obesity crisis.

    ABSTRACT: This paper summarizes the evidence on the relationship between physical activity (PA) and cardiovascular disease (CVD) that has been published mainly during the past 10 years. The primary focus is on aspects related to the primary prevention of the clinical events of coronary heart disease and stroke. The material was collected by conducting a search of the Medline, Embase and Cochrane electronic databases to identify systematic reviews and meta-analyses having been published on the relationship between PA and CVD since 2002. The terms used for the exposure were physical activity or exercise, and for the outcome the following terms: cardiovascular disease, coronary heart disease, coronary artery disease, coronary disease, myocardial infarction, stroke, peripheral vascular disease or peripheral arterial disease. In addition, committee reports on the topic were identified through scientific meetings and by personal communication. A large majority of the studies included in the reviews were prospective cohort studies of at-risk populations. The quantity and quality of scientific data on the cardiovascular and other health-related effects of physical activity has increased greatly during the past decade. The evidence now shows convincingly that insufficient physical activity is one of the key causal risk factors of CVD, particularly of the most prevalent of them, CHD and stroke. The effects of insufficient physical activity are mediated partly through the traditional major risk factors, and partly they are independent. This rather recently shown fact emphasizes the essential, irreplaceable role of PA for cardiovascular health. Strong epidemiological evidence indicates that a major part of the preventive effect of PA can be attained by activity that is applicable on a large scale in all European populations: moderate-intensity endurance or aerobic activity such as brisk walking on several days during the week, in total approximately 150 minutes per week. Higher, still attainable amounts of moderate-intensity PA would further increase the CV and other health benefits, particularly because PA in all domains, during leisure time, in domestic chores, in transport, and in occupational work has been shown to be effective. Prevention of CVD through increased PA brings also several other health benefits by decreasing substantially the risk of several of the most common chronic diseases and by improving and maintaining physical, mental, and cognitive functions. PA also decreases, even totally counterbalances in overweight persons the risk of CVD, as well as several other health hazards of being overweight and obese. It is clear that sufficient physical activity is an essential factor in attaining and maintaining health and functional capacity at all ages, and without sufficient physical activity all attempts to improve the health of the Europeans remain deficient.
