Effects of Decreasing Sugar-Sweetened Beverage Consumption on Body Weight in Adolescents: A Randomized, Controlled Pilot Study
OBJECTIVE . The role of sugar-sweetened beverages ( SSBs ) in promoting obesity is controversial . Observational data link SSB consumption with excessive weight gain ; however , r and omized , controlled trials are lacking and necessary to resolve the debate . We conducted a pilot study to examine the effect of decreasing SSB consumption on body weight . METHODS . We r and omly assigned 103 adolescents aged 13 to 18 years who regularly consumed SSBs to intervention and control groups . The intervention , 25 weeks in duration , relied largely on home deliveries of noncaloric beverages to displace SSBs and thereby decrease consumption . Change in  SSB consumption was the main process measure , and change in body mass index ( BMI ) was the primary end point . RESULTS . All of the r and omly assigned subjects completed the study . Consumption of SSBs  decreased by 82 % in the intervention group and did not change in the control group . Change in BMI , adjusted for gender and age , was 0.07 ± 0.14 kg/m2 ( mean ± SE ) for the intervention group and 0.21 ± 0.15 kg/m2 for the control group . The net difference , −0.14 ± 0.21 kg/m2 , was not significant overall . However , baseline BMI was a significant effect modifier . Among the subjects in the upper baseline- BMI tertile , BMI change differed significantly between the intervention ( −0.63 ± 0.23 kg/m2 ) and control ( + 0.12 ± 0.26 kg/m2 ) groups , a net effect of −0.75 ± 0.34 kg/m2 . The interaction between weight change and baseline BMI was not attributable to baseline consumption of SSBs . CONCLUSIONS . A simple environmental intervention almost completely eliminated SSB consumption in a diverse group of adolescents . The beneficial effect on body weight of reducing SSB consumption increased with increasing baseline body weight , offering additional support for American Academy of Pediatrics guidelines to limit SSB consumption
