Associations of positive childhood experiences with binge-eating disorder characteristics and intuitive eating among college students.

Childhood experiences encompass both adverse and positive childhood events. Adverse childhood experiences are positively associated with binge-eating disorder characteristics and inversely associated with intuitive eating in adults. However, to what extent positive childhood experiences (PCEs) are associated with binge-eating disorder characteristics and intuitive eating remains unclear. This study examined the associations of cumulative and individual PCEs with binge-eating disorder characteristics and intuitive eating among college students. Data were collected from 828 college students in 2022 (54.5% female, Mage 20.9 ± 2.6 years). PCEs were assessed using the Benevolent Childhood Experiences scale. Binge-eating disorder characteristics were assessed with the Questionnaire on Eating and Weight Patterns-5. Intuitive eating was assessed with the Intuitive Eating Scale-2. Associations of PCEs with binge-eating disorder characteristics and intuitive eating were examined using modified Poisson regressions and linear regressions. PCEs were cumulatively associated with binge-eating disorder characteristics and intuitive eating (p for trend <.05). College students in the low PCEs category (0-4 PCEs) had 1.37-1.92 times the prevalence of binge-eating disorder characteristics and had 3.89 points lower intuitive eating score than those in the high PCEs category (9-10 PCEs). Among the individual PCEs, intrapersonal PCE (i.e., feeling comfortable with oneself during childhood) was associated with both a lower prevalence of binge-eating disorder characteristics (aPR = 0.56-0.76) and a higher score of intuitive eating (adjusted β = 1.87, 95% CI = 1.28-2.46) after adjustment for sociodemographic variables. Findings from this study suggest that PCEs may play a role in eating behaviors of college students. Future studies with nationally representative samples should prospectively examine associations of PCEs with binge-eating disorder characteristics and intuitive eating and explore the underlying mechanisms of the associations between PCEs and eating behaviors.
