Changing perceptions of the childhood obesity epidemic.

OBJECTIVES To examine changes in public attitudes about childhood obesity and support for prevention. METHODS RTI surveyed US households (N = 1047 and N = 1139) about perceived severity, causes, and support for specific obesity interventions. Logistic regressions examined differences in obesity attitudes and support for prevention. RESULTS Perceived health threat of childhood obesity increased between the 2 surveys. Support increased for interventions such as regulation of restaurant portions and fast food advertising. Logistic regressions revealed differences among sociodemographic groups. CONCLUSIONS Public support for childhood obesity prevention is increasing. Policy makers can use these findings to develop appropriate prevention strategies.
