Introduction: Disordered eating is prevalent among youth from varying socioeconomic backgrounds; however, conceptual models of disordered eating extending to youth from low-income backgrounds are limited. Higher weight is associated with disordered eating, which may be particularly salient among youth from low-income backgrounds due to the high rates of obesity within this population. Specific socioenvironmental factors, including parental weight concern and family mealtime routines, are associated with lower levels of disordered eating and may present as modifiable factors that weaken the relation between weight and disordered eating among adolescents. The present study examined the association between adolescent weight and disordered eating among a sample of youth from a low-income background and examined the potential moderating effect of parental weight concern and family meals. Methods: Adolescents ages 12-17 (N = 73) and one parent/guardian from a low-income background, as defined by an income-to-needs ratio < 200% of the federal poverty threshold, completed self-report questionnaires as part of a larger study examining stress and eating. Adolescents (Mage = 13.6 years, SD = 1.4, 47.9% female) completed measures of disordered eating and perception of parental concern of the adolescent’s weight. Parents (Mage = 40.1 years, SD = 7.53, 93.2% female) completed measures of basic demographics and their adolescent’s mealtime routines. Adolescent height and weight were objectively measured to calculate a BMI z-score.Results: Bootstrapped linear regression models demonstrated that adolescent weight was significantly positively associated with disordered eating (95% CI [.26, .54]), after controlling for sex. The moderation model for parental weight concern was significant, F(4, 68) = 18.44, p < .01, with the bootstrapped regression coefficient indicating a significant interaction 95% CI (.03, .23). Simple slopes test revealed that the relation between adolescent zBMI and disordered eating was no longer significant at low levels of parental weight concern. The moderation model for family meals was also significant F(4, 68) = 11.99, p < .01, with a significant bootstrapped regression coefficient for the interaction term 95% CI (-.07, -.01), such that more frequent meals weakened the association between adolescent zBMI and disordered eating.Discussion: The present study found that higher weight is associated with greater levels of disordered eating among adolescents from a low-income background. This finding presents an important extension to previous literature that has primarily conceptualized disordered eating within upper-class, White, female adolescents. In addition, lower levels of parental weight concern and more frequent family meals significantly buffered the association between weight and disordered eating in this at-risk, yet understudied population. Both parental weight concern and family meals present as modifiable factors within the family environment that may serve as targets for intervention. Future research is needed to elucidate additional factors affecting the relation between weight and disordered eating among adolescents from disadvantaged backgrounds and to utilize larger, longitudinal studies which may allow for stratification by sex or race/ethnicity and temporal investigation of weight and disordered eating.
