Abstract P278: Patterns of Eating Associated With Sleep Duration, Insomnia, Daytime Sleepiness, and Overall Sleep Quality Among Individuals of Mexican Descent at the US-Mexico Border

Abstract

Introduction: Previous studies have linked sleep to risk of diabetes and obesity, at least partially via alterations in food intake. Diabetes and obesity are common among Hispanics/Latinos, and studies are needed to better clarify the role of sleep in health among this group. Methods: Data were collected from N=100 adults (age 18-60, 53% female) of Mexican descent in the city of Nogales, AZ (66% not born in the US, 33% 1 st -generation). Surveys were presented in English or Spanish. Eating Patterns were assessed with the 3-Factor Eating Questionnaire (3FEQ), which resulted in a total score and subscales for “cognitive restraint,” “uncontrolled eating, “and “emotional eating.” Insomnia was assessed with the Insomnia Severity Index (ISI), Sleepiness with the Epworth Sleepiness Scale (ESS), Sleep quality with the Pittsburgh Sleep Quality Index (PSQI), and weekday and weekend sleep duration with the Sleep Timing Questionnaire (STQ). Covariates included age, sex, and immigrant status. Results: See Table. Eating patterns associated with insomnia, sleep quality, sleepiness, and weekend (but not weekday) sleep duration. Regarding subscale scores, relationships were generally seen between sleep and emotional eating and unrestricted eating, and not cognitive restraint. Conclusions: Several different aspects of sleep quality were associated with eating patterns at the US-Mexico border, particularly in the area of unrestricted eating and emotional eating. This suggests possible mechanisms linking sleep and obesity in Hispanics/Latinos.
