Screening and Interventions for Obesity in Adults: Summary of the Evidence for the U.S. Preventive Services Task Force

View larger version (29K): [in a new window]   Figure 1. Differences in mean weight loss between intervention and control groups for counseling and behavioral interventions. Only studies for which the difference in mean weight loss could be calculated are included. Error bars represent 95% CIs and are presented for studies in which those data were available. Data presented are as close as possible to 1-year follow-up. An asterisk indicates that the difference was statistically significant (P < 0.05) but there were insufficient data to calculate CIs. B = behavioral therapy; D = diet; E = exercise; EP = exercise program; EQ = exercise equipment; L = lottery entry; MR = meal replacement; SES = socioeconomic status. +++ = high intensity; ++ = moderate intensity; + = low intensity.

Only studies for which the difference in mean weight loss could be calculated are included; each arm is represented by a data point. Error bars represent 95% CIs and are presented for studies in which those data were available. Intensity of co-interventions was not assessed because most trials provided insufficient information for evaluation. An asterisk indicates that the difference was statistically significant (P < 0.05) but there were insufficient data to calculate CIs. B = behavioral therapy; BID = twice daily; D = diet; E = exercise; QD = daily; TID = 3 times daily.
