Conclusions Meta- analysis of data from prospect i ve cohort studies showed small , inconsistent and non-significant associations between sedentary behavior and body weight
Background The cumulative effect of too much sedentary behavior may contribute to  weight gain and obesity .
Objective The aim of this study was to conduct a systematic review and meta- analysis of prospect i ve cohorts and r and omized controlled studies to determine the association between sedentary  behavior  and body weight and obesity in adults .
Predictors of weight change in men: Results from The Health Professionals Follow-Up Study
OBJECTIVE : Since the prevalence of adult obesity is increasing in the United States , we examined the effect of changing common habits ( exercise , TV viewing , smoking and eating habits ) on four year change in body weight . DESIGN : A prospect i ve cohort study of US male health professionals with follow-up from 1988–1992 . Participants were 19 478 men aged 40–75 in 1986 , who were free of cancer , coronary heart disease , stroke and diabetes . METHODS : Multiple regression was used to determine the association between four year change in body weight ( from 1988–1992 ) and common habits , after adjusting for baseline age , hypertension and hypercholesterolemia . RESULTS : For middle aged men , vigorous activity was associated with weight reduction and TV/VCR viewing and eating between meals with weight gain . Quitting smoking and a history of voluntary weight loss prior to the study period were consistently related to weight increase . Recently being on a diet was more strongly associated with weight loss among older men . Over the four year follow-up period , middle-aged men who increased their exercise  , decreased  TV viewing  and stopped eating between meals  , lost an average weight of −1.4 kg ( 95 % confidence interval (CI)−1.6 – −1.1 kg ) , compared to a weight gain of 1.4 kg among the overall population . The prevalence of obesity  among middle-aged men was lowest among those who maintained a relatively high level of vigorous physical activity , compared to those who were relatively sedentary . CONCLUSION : These data suggest that improvement in the mix of health habits , particularly increasing vigorous activity , as well as decreasing TV use and changing eating habits , results in weight maintenance or a modest weight loss over four years
