Abstract
OBJECTIVE: Previous research has found an increasing co-occurrence of dieting and substance use behavior among adolescent girls. However, to date few studies have examined the temporal ordering of these behaviors. Further, limited research has been conducted to explore whether the pathways are similar among both White and Black girls. METHOD: For the current study 1580 girls (grade 6-11; 78.2% White; 21.8% Black) provided data on their dieting behavior and substance use. A cross-lagged panel design was used to examine the concurrent and prospective relationship between dieting behavior and substance use across one year, then by race. RESULTS: Among the full sample of girls, there was a significant concurrent relationship. Additionally, dieting behavior predicted substance use one year later, but the inverse relationship was not found. For the stratified analysis, dieting behavior and substance use were not correlated among Black girls at either time point, however concurrent relationships were found for White girls. For the prospective pathways non-significant effects were found for both groups. DISCUSSION: These findings provide support for a temporal relationship between dieting behavior and substance use, such that the former predicts risk for the latter. However, when examined by race, some pathways of the full sample were found for White girls, whereas Black girls did not report an association between study variables. Thus, future studies should consider the impact of race within risk pathways.
