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 .
Difference in caloric expenditure in sitting versus standing desks.
BACKGROUND Traditional desks require students to sit ; however , recently schools have provided students with nontraditional st and ing desks . The purpose of this study was to investigate differences in caloric expenditure of young adults while sitting at a st and ard classroom desk and st and ing at a nontraditional st and ing classroom desk . METHODS Twenty ( 10 male/10 female ) young ( 22.8 ± 1.9 y ) , healthy participants reported to the laboratory between the hours of 7:00 AM and 2:00 PM following a 12-h fast and 48-h break in exercise . Participants were r and omly assigned to perform a series of mathematical problems either sitting at a normal classroom desk or st and ing at a nontraditional st and ing desk . Inspired and expired gases were collected for 45-min for the determination of oxygen consumption ( VO2 ) , carbon dioxide production ( VCO2 ) , and minute ventilation ( VE ) using a metabolic gas system . RESULTS There were significant increases from sitting to st and ing in VO2 ( 0.22 ± 0.05 vs. 0.28 ± 0.05 L·min-1 , P ≤ .0001 ) , VCO2 ( 0.18 ± 0.05 vs. 0.24 ± 0.050 L·min-1 , P ≤ .0001 ) , VE ( 7.72 ± 0.67 vs. 9.41 ± 1.20 L·min-1 , P ≤ .0001 ) , and kilocalories expended per minute ( 1.36 ± 0.20 kcal/min , P ≤ .0001 vs. 1.02 ± 0.22 kcal/min , P ≤ .0001 ) . CONCLUSIONS Results indicate a significant increase in caloric expenditure in subjects that were st and ing at a st and ing classroom desk compared with sitting at a st and ard classroom desk
