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 .
Maintaining a Healthy BMI: Data From a 16-Year Study of Young Australian Women.
INTRODUCTION The aims of this prospect i ve cohort study were to examine 16-year trajectories of weight and BMI in young adult women who had a healthy BMI in 1996 and determinants of remaining in the healthy BMI category . METHODS A total of 4,881 women with healthy BMI at baseline and either healthy , overweight , or obese BMI at 16-year follow-up reported their weight , height , health , and health behaviors in six surveys of the Australian Longitudinal Study on Women 's Health between 1996 ( aged 18 - 23 years ) and 2012 ( aged 34 - 39 years ) . Determinants of BMI maintenance were estimated using binary logistic regression and generalized estimating equations in 2015 . RESULTS Almost 60 % remained in the healthy BMI category from 1996 to 2012 , ( mean weight gain , 0.19 kg/year ) , 29 % transitioned to overweight BMI ( 0.83 kg/year ) , and 11.6 % transitioned to obese ( 1.73 kg/year ) . The mean rates of annual weight gain in each group were consistent over time . Only three factors ( low alcohol , moderate/high physical activity , having a university degree ) were positively associated with maintaining a healthy BMI . Additional behavioral factors ( smoking , high sitting time , energy intake , dieting , takeaway food , and use of oral contraceptives ) , as well as blue collar occupation , separation/divorce/widowhood , and major illness were negatively associated with BMI maintenance . CONCLUSIONS To prevent the transition from healthy to overweight/obese BMI , weight gain must be limited to < 0.5 kg/year . Women with healthy BMI , but with higher rates of weight gain in their early 20s , could be identified by health professionals for assistance with prevention of becoming overweight/obese
