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 .
Associations between sitting time and weight in young adult Australian women.
OBJECTIVE Sedentary behaviour may be a contributor to weight gain in today 's young adult women , who are gaining weight faster than women in their mothers ' generation . The aim was to examine the relationships between sitting time and weight in young women . METHOD Data were from women born in 1973 - 1978 who completed surveys in 2000 , 2003 and 2006 for the Australian Longitudinal Study on Women 's Health . Associations between concurrent changes in sitting-time and weight , and prospect i ve associations between these variables , were examined using ANOVA and linear regressions , stratified by BMI -category in 2000 ( n=5562 ) . RESULTS Among overweight and obese women , percentage weight change from 2000 to 2006 was higher in those whose  sitting time  increased ( > 20 % ) than in those whose sitting time decreased ( > 20 % ) over the same period ( p<0.05 ) . Conversely , percentage change in sitting time was significantly higher in those who gained weight ( > 5 % ) than in those who lost weight ( > 5 % ) ( p<0.05 ) . There were no prospect i ve associations between ( change in )  sitting time and weight change , or between ( change in ) weight and change in sitting time . CONCLUSION The results confirm associations between concurrent changes in weight and changes in sitting time  in overweight and obese women , but no prospect i ve relationships were found
