ABSTRACT Investigate whether TV viewing and recognition of snack food advertisements were associated with snack food consumption and the odds of being overweight or obese.
Cross-sectional internet-based survey.
University of Alberta, Edmonton, Canada.
Undergraduate university students aged 18 to 25 years (N = 613).
Self-reported TV viewing, energy-dense snack consumption, snacking while viewing TV, and body weight.
Hypothesis testing was completed using multiple analysis of variance, analysis of covariance, and logistic regression.
Students reporting medium or high TV viewership snacked more frequently while watching TV and recognized more advertising than students who were considered low viewers. High viewers also reported more consumption of energy-dense snacks than low viewers. Snacking frequency appeared to be related to TV viewing and place of residence, but the association between snacking frequency and TV viewing was not accounted for by advertising. Conversely, the association between TV viewing and consumption of energy-dense snacks was accounted for by advertising recognition. Finally, male students (odds ratio [OR], 2.78; 99% confidence interval [CI], 1.68-4.59) and medium (OR, 3.11; 99% CI, 1.37-7.08) and high (OR, 5.47; 99% CI, 1.97-15.16) TVviewers had higher odds of being overweight or obese.
Associations were found among TV viewing, energy-dense snack consumption, and snacking behavior, and between TV viewing and body weight status.

    • "A previous study reported that odds of being obese was 1.87 times greater for children viewing TV more than 3 hr/day, compared to those watching for less than 1 hr (Hernández et al., 1999), which is congruent with the findings of the current study, showing significantly higher BMI among subjects with screen time of 3 or more hr/day, compared to those with less than 1 hr/day. A previous study reported an association of sedentary behavior related to screen time with lowering of metabolic rates, increased consumption of snacks, and exposure to junk food advertisements, which may contribute to increase in BMI (Robinson, 2001; Thompson, Spence, Raine, & Laing, 2008).

    ABSTRACT: The purpose of this study was to investigate the association of sociodemographic, psychosocial, and behavioral characteristics with screen time among school-age children in Korea. This study employed a nonexperimental, cross-sectional study design. A total of 370 children attending four elementary schools participated in the study. Self-report method was used, and instruments included screen time (time spent on TV/video/computer/video games), sleep duration, eating behavior, pros and cons of exercise, and exercise self-efficacy. According to the results, 45.7% of the children had screen time of 1-2.9 hr/day and 8.9% had 3 or more hr/day. Increased screen time showed an association with gender (boy), higher body mass index, fast food consumption, higher cons of exercise, having a working mother, and attendance at a school in an inner city area (p < .05). Understanding the factors associated with screen time may provide useful information in the development of health promotion programs aimed at decreasing sedentary behaviors.

    • "In addition to possible physiologic mechanisms, there are possible behavioral explanations; for example, extended time spent viewing TV may lead to social isolation which adversely affects mental well-being [19]. Another possible explanation is the documented association between TV viewing and unhealthy (snack) food and beverage intake [20] [21]. With respect to the other side of energy balance, it has been hypothesized that TV viewing or other leisuretime sedentary behaviors may be substituted for beneficial physical activity that reduces the risk of depression [22].

    ABSTRACT: Objective. To explore the associations between sitting time in various domains and mental health for workers and nonworkers and the role of weight status. Design. Cross-sectional analyses were performed for 1064 respondents (47% men, mean age 59 years) from the Doetinchem Cohort Study 2008-2009. Sedentary behavior was measured by self-reported time spent sitting during transport, leisure time, and at work. Mental health was assessed by the Mental Health Inventory (MHI-5). BMI was calculated based on measured body height and weight. Results. Neither sitting time during transport nor at work was associated with mental health. In the working population, sitting during leisure time, and particularly TV viewing, was associated with poorer mental health. BMI was an effect modifier in this association with significant positive associations for healthy-weight non-workers and obese workers. Conclusion. Both BMI and working status were effect modifiers in the relation between TV viewing and mental health. More longitudinal research is needed to confirm the results and to gain insight into the causality and the underlying mechanisms for the complex relationships among sedentary behaviors, BMI, working status, and mental health.

    • "Moreover, when indoors at home, people are more likely to snack. Medium and high TV viewership is associated with snacking more frequently, and frequent viewers also report more consumption of energy-dense snacks (Thomson et al. 2008). Thus, one benefit of outdoor recreation, from a health perspective, is a decreased likelihood of overeating and suffering pollution-related health problems. "

    ABSTRACT: The research literature on outdoor recreation as it relates to human health is vast and growing. To help policymakers take new and emerging findings into account when designing recreation and park services and initiatives for the 21st century, this paper summarizes the salient issues and identifies research gaps. It considers how being outside in natural surroundings may improve health and how outdoor physical activities benefit participants. Particular attention is given to children’s health problems that can be mitigated through outdoor play, sports, and nature study. The paper describes approaches to measuring physical activity and recent trends in park visitation and outdoor activity participation. It looks at variables that affect participation in outdoor activities and considers the projected demographic changes that will affect policymaking in this arena. The findings of this literature review point to potential new directions for outdoor recreation policy, as well as new policy questions to be explored.
