Depression symptoms and night eating in young adulthood.

Abstract

We estimated cross-sectional and longitudinal associations between depression symptoms and night eating in young adults. Data were drawn from a longitudinal investigation of students age 12-13years at inception in 1999-2000, in Montreal, Canada. Depression symptoms were measured with the Depressive Symptoms Scale (DSS) 20times from age 12 to 17, and with the Major Depression Inventory (MDI) post-high school at ages 20 and 24. Night eating was measured at age 24. The association between depression symptoms and night eating was estimated in multivariable logistic regression models adjusted for sex, age and mother university-educated. 9% of 829 participants (n = 77) reported night eating. In cross-sectional analysis, the adjusted odds ratio (OR) estimate for MDI scores (range 0-50) was 1.04 (1.01, 1.07). In longitudinal analyses, the OR estimates were 1.75 (1.20, 2.55) for DSS scores (range 1-4) and 1.03 (1.002, 1.06) for the MDI. Depression symptoms are associated with night eating in young adults cross-sectionally and possibly longitudinally. Treatment of depression symptoms may be important in preventing night eating, a core symptom of the Night Eating Syndrome. Level III, cohort analytic study.
