The interplay between food insecurity and family factors in relation to disordered eating in adolescence

This study examined the association between food insecurity and both binge eating and unhealthy weight-control behaviors (UWCBs) and assessed whether such associations differ by factors within the family environment. Data were collected from a diverse sample of adolescents (M_age = 14.5 years; 54.1% female) and their parents/guardians (N = 2137 dyads) participating in EAT 2010 (Eating and Activity over Time). Food-insecure adolescents were more likely to report binge eating (prevalence ratio [PR] = 1.94; 95% confidence interval [CI]: 1.41-2.69) and UWCBs (PR = 1.34; 95% CI: 1.21-1.49) than food-secure adolescents. Family meal importance (p = .03) and family communication (p < .001) significantly moderated the association between food insecurity and UWCBs, such that the association was weaker at lower levels of these factors. Significant interactions with parental weight talk/concern (p < .001) and weight teasing (p = .04) indicated a weaker association between food insecurity and UWCBs in the presence of these factors. Findings indicate that the association between food insecurity and UWCBs among youth is less salient in the absence of family protective factors and in the presence of family risk factors for UWCBs, indicating the importance of targeting food insecurity itself, regardless of the presence of family risk or protective factors for UWCBs.
