title: Correlates of body mass index, weight goals, and weight-management practices among adolescents.
abstract: The study examined associations among physical activity, cigarette smoking, body mass index, perceptions of body weight, weight-management goals, and weight-management behaviors of public high school adolescents. The CDC Youth Risk Behavior Survey provided a cross-sectional sample (n = 3,089) of public high school students in South Carolina. Logistic regression models were constructed separately for four race-gender groups. Adjusted odds ratios and 95% confidence intervals were calculated to determine the magnitude of associations. Based on self-reported height and weight, 13% of students were overweight, while 15% were at risk for becoming overweight. However, 42% of students were trying to lose weight, and 22% were trying to maintain current weight. Female students were less likely than male students to be overweight, but more likely to be attempting to lose weight. Extreme weight control practices were reported by 27% of the sample. Among Black females trying to lose weight, positive associations were observed for strengthening exercises (OR = 1.55), but that relationship was associated inversely in Black males (OR = .600). Among White females, attempted weight loss was associated with strengthening exercises (OR = 1.72) and cigarette smoking (OR = 1.54). For White males, attempted weight loss was associated positively with vigorous exercise (OR = 1.41) and inversely related to moderate exercise (OR = .617). Effective weight-management practices for adolescents should focus on appropriate eating behaviors, physical activity, and low-fat/calorie diets. Multicomponent weight management interventions should be conducted within a coordinated school health framework.
