“…24 However in this study the relationship between television viewing and overweight was modi®ed by physical activity; a ®nding consistent with other cross-sectional studies that have found physical activity or physical ®tness to modify this relationship. 21,22 Our study has produced mixed results, in that there was a lack of a clear relationship between overweight and television viewing for the most sedentary category but a relationship appeared to exist for other activity categories. This suggests that some active people may compensate for their participation in physical activity by increased nutritional intake or increased sedentary periods in other parts of their day.…”

“…9±12,14,16,17,20 Fewer studies have examined the relationship between overweight and obesity, television viewing, and physical activity in adults. One study of adult males 21 and another of adult females, 22 found signi®-cant positive associations between body fat percentage and hours of television viewing. A positive association between television viewing and BMI was reported among adult Pima Indians, together with a negative relationship between television viewing and physical activity.…”

OBJECTIVES: To investigate the effect of physical activity on the association between television viewing and overweight (body mass index (BMI) ! 25 kgam 2 ). DESIGN: Cross-sectional study administered by interview to adults randomly selected from the electronic white pages. SUBJECTS: 3392 adults (64% response rate) from a representative population sample in the State of New South Wales, Australia. MEASUREMENTS: Self-reported height and weight, two-week leisure-time physical activity recall, one-week average television viewing recall. RESULTS: BMI and physical activity patterns were both associated with hours of television watched. Compared to those participants who reported watching less than one hour of television per day, those watching 1 to 2.5 hours were 93% more likely to be overweight (BMI ! 25 kgam 2 ), those watching 2.5 to 4 hours were 183% more likely to be overweight, those watching more than 4 hours per day were four times more likely to be overweight. Physical activity was not directly associated with being overweight, but an interaction between activity and television watching was present. Respondents in the low, moderate and high physical activity categories who reported watching more than 4 hours of television per day were twice as likely to be overweight compared to those who watched less than one hour of television per day, irrespective of physical activity participation. CONCLUSIONS: With approximately half the Australian adult population overweight or obese, these ®ndings indicate that public health strategies to reduce overweight and prevent weight gain may need to focus on reducing sedentary behaviours such as television viewing in addition to increasing physical activity.

Abstract-Obesity is a major influence on the development and course of cardiovascular diseases and affects physical and social functioning and quality of life. The importance of effective interventions to reduce obesity and related health risks has increased in recent decades because the number of adults and children who are obese has reached epidemic proportions. To prevent the development of overweight and obesity throughout the life course, population-based strategies that improve social and physical environmental contexts for healthful eating and physical activity are essential. Population-based approaches to obesity prevention are complementary to clinical preventive strategies and also to treatment programs for those who are already obese. This American Heart Association scientific statement aims: 1) to raise awareness of the importance of undertaking population-based initiatives specifically geared to the prevention of excess weight gain in adults and children; 2) to describe considerations for undertaking obesity prevention overall and in key risk subgroups; 3) to differentiate environmental and policy approaches to obesity prevention from those used in clinical prevention and obesity treatment; 4) to identify potential targets of environmental and policy change using an ecological model that includes multiple layers of influences on eating and physical activity across multiple societal sectors; and 5) to highlight the spectrum of potentially relevant interventions and the nature of evidence needed to inform population-based approaches. The evidence-based experience for population-wide approaches to obesity prevention is highlighted. (Circulation. 2008;118:428-464.)

“…There are at least 2 explanations for the observed positive association between TV watching and diabetes risk. First, TV watching is directly related to obesity and weight gain, [11][12][13][14][15]33 probably due to lower energy expenditure (ie, less physical activity) and higher caloric intake. Second, participants who spent more time watching TV tended to eat more red meat, processed meat, snacks, refined grains, and sweets and fewer vegetables, fruits, and whole grains.…”
