Associations among social jetlag, sleep-related characteristics, premenstrual symptoms, depression, and body mass index of female nursing students

Abstract

Purpose This study aimed to identify the predictors of female nursing students' body mass index (BMI), including social jetlag. Design and Methods This secondary data analysis of a cross-sectional survey conducted in 2015 included data of 304 female undergraduate nursing students. A hierarchical regression analysis was performed to identify the predictors of BMI. Findings Social jetlag was the most potent predictor of BMI, followed by premenstrual symptoms and sleep quality. Practice Implications This study presents foundational data for developing interventions for social jetlag management as a strategy to prevent obesity in female nursing students by identifying factors predicting BMI.
