Our study is the first large multicenter study to report the effect of sibutramine pharmacotherapy on weight loss in obese adolescents. The addition of sibutramine to a behavior therapy program in our 12-month, placebo-controlled study conducted in obese adolescents 12 to 16 years of age resulted in statistically significant improvements in BMI. At month 12, the estimated mean change in BMI for sibutramine plus behavior therapy was −3.1 kg/m2 versus −0.3 kg/m2 for placebo plus behavior therapy (P < 0.001 by linear mixed-effects model).

Data on participants who did not pass the screening process were not collected. Eight participants (5 sibutramine recipients and 3 placebo recipients) did not record any postbaseline data, and we excluded them from the modified intention-to-treat population data set. The proportions of participants who prematurely discontinued treatment because of an adverse event were 23 of 368 patients (6%) in the sibutramine group and 7 of 130 patients (5%) in the placebo group (  = 0.83). *Patients were randomly assigned to the sibutramine or placebo group in a 3:1 ratio. †   = 0.80 vs. placebo (chi-square test). ‡   = 0.001 vs. placebo (chi-square test).

All data are estimated means from the linear mixed-effects model. The model indicated statistically significant differences between treatment groups at all postbaseline visits (  < 0.001). An additional visit occurred at month 6.5 after possible dose uptitration, which resulted in a smaller visit window for month 6 compared with other visits after month 1, leading to a reduction in participants recording data at month 6.
