BACKGROUND: Food insecurity affects 13 million children in the United States. Body dissatisfaction is also prevalent, affecting up to 46% of children. Both food insecurity and body dissatisfaction are associated with poor health outcomes, and both are associated with body weight and racial/ethnic disparities. The association between food insecurity and body dissatisfaction among children has not been examined. OBJECTIVE: The purpose of this study was twofold: to examine, in a sample of children in grades 4 through 8, the relationship of child food insecurity with body dissatisfaction and to gain an understanding of the interactive roles of body mass index (BMI), race/ethnicity, and sex in the relationship between food insecurity and body dissatisfaction. DESIGN: This was a cross-sectional study. PARTICIPANTS/ SETTING: This study examined data obtained from 14,768 children in grades 4 through 8 from 54 public schools in California between 2014 and 2016. MAIN OUTCOME MEASURES: The primary outcome of interest was body dissatisfaction (five items converted to a binary indicator), and the exposure of interest was child-reported food insecurity (three items converted to a binary indicator). Subsets of validated questionnaires were used to assess body dissatisfaction and food insecurity. STATISTICAL ANALYSES PERFORMED: Data were analyzed using multivariable logistic regression, and effect modification was examined by BMI category (underweight, normal, overweight, obese), race/ethnicity, and sex. RESULTS: In this large and diverse sample, after adjusting for cofounders, children experiencing food insecurity, in all BMI categories and from all racial/ethnic backgrounds, had higher odds of body dissatisfaction than their food-secure counterparts. The strength of the relationship differed by BMI and race/ethnicity, with the strongest associations observed for African-American children (odds ratio=2.32; P<0.001) and children with a normal children (odds ratio=1.76; P<0.001). CONCLUSIONS: Experiencing food insecurity was associated with greater body dissatisfaction, with the magnitude of the association modified by BMI and race/ethnicity.
