Background: An estimated 13 million children in the United States live in food-insecurehouseholds, which has been linked to greater symptoms of depression and anxiety, lowerself-esteem, and eating disorders. Weight dissatisfaction is another factor found to be associatedwith those same outcomes, but to date, studies looking at the association between food security(FS) and weight dissatisfaction has not been done using a national database. Understanding therelationship between FS and weight dissatisfaction can help in developing early interventions forat-risk groups.Objective: To evaluate the association between a child's FS level and their self-perception withand satisfaction of their weight status. Secondary outcomes include the association between sexand race/ethnicity with weight self-perception and satisfaction among individuals with lower FSlevels.Methods: This is a retrospective cohort study of the National Health and Nutrition ExaminationSurvey data from 2005-2016. Respondents were categorized under one of four FS categories:full, marginal, low, and very low in the database. Answers to the survey questions "How do youconsider your weight?" and "What are you trying to do about your weight?" were used tocategorize weight self-perception and weight satisfaction. The chi-squared test of independencewas used to analyze weight survey data, with a significance set at p ≤ 0.05.Results: A total of 8,717 children aged 8-15 were included in the study. Both weightself-perception (p ≤ 0.05) and weight satisfaction (p ≤ 0.05) significantly differed by FS level.With regards to weight self-perception, more of those endorsing full FS considered themselves tobe about the right weight (75.2%) compared to those with low (70.0%) and very low FS (69.7%)(p ≤ 0.05). More respondents with low (21.5%) and very low FS (20.2%) considered themselvesto be fat compared to those with high FS (17.2%) (p ≤ 0.05). Weight dissatisfaction was morecommon among those with low (54.12%) and very low (57.30%) FS compared to thoseendorsing full FS (47.39%) (p ≤ 0.05). Among respondents with low and very low FS, sexdifferences in both weight self-perception (p ≤ 0.05) and weight satisfaction (p ≤ 0.05) wereseen. Racial differences in weight satisfaction (p ≤ 0.05) were seen, but racial differences inweight self-perception (p > 0.05) were not seen.Conclusion: Lower FS levels may influence children's weight satisfaction and self-perception.Sex may influence both weight satisfaction self-perception and race/ethnicity may influenceweight self-perception among children endorsing lower FS levels. Future studies should usein-depth questionnaires and evaluate other variables such as overall self-esteem, mental health,and eating behaviors to better understand this relationship.
