Technical Abstract: The objective of the current study was to determine which Mexican American children benefited most from an obesity prevention program. Data used were taken from a larger randomized clinical trial in which participants received either an intensive (IP) or a self-help (SH) program for preventing the onset of adult obesity. Children in IP lost significantly more weight than those in SH. This study used children from the IP (n=106) condition only. Children aged 10 to 14 years were classified according to weight status (normal (N), n=35; at risk of overweight (ARO), n=21; overweight (O), n=50). N children showed no change in body mass index standardized for age and gender (zbmi; t=.85, p<.001 at 12 months) and little change in weight status over time (>97% remained N). ARO and O children, however, showed significant changes in zbmi (t=.54, p<.01; t=.81, p<.001, respectively) and weight status from baseline to 12 months (48% of ARO changed to N and 10% of O changed to ARO). The decrease in zbmi for ARO children was significantly greater than that of the O children (F=4.8, p<.05), indicating intervention may be most effective for ARO children. We concluded that it is important to understand differences in how prevention programs benefit participants from various weight classifications.
