Public health leaders are faced with a growing epidemic of pediatric obesity in the United States. Hispanic children are particularly in need of an effective public health treatment intervention, harboring the highest incidence of childhood obesity among any ethnicity in the United States (Butte, Cai, Cole, & Comuzzie, 2006; Ogden et al., 2006) and reduced access to health care services (Wang & Zhang, 2006). The purpose of the current study was to determine whether there were correlations and prediction factors among parental health locus of control, key demographic variables, and pediatric obesity treatment outcomes. To answer the proposed research questions, archived data were analyzed. Correlations were assessed between each of the health locus of control subscales and mother’s age, child’s age, mother’s education level, mother’s marital status, mother’s number of years in the country, grade level of the child, and treatment outcome. In addition, logistic regressions were performed between the health locus of control subscales and treatment outcome. The results showed that the demographic variable of mother’s age was positively significantly correlated with the external, powerful others subscale. In addition, the combination of the demographic variables of mother’s age and level of education were significantly correlated with internal subscale. The results of the current study have multiple implications for the public health sector, including strategies for the effective dissemination of information.
