“…On an aggregate level, stressful experiences in university correlated with poorer quality sleep (Fortunato & Harsh, 2006). Similarly, repeated measures studies showed that in the first year of university, sleep quantity and quality were lower on days (Galambos et al, 2009) and in months (Galambos et al, 2011) when stress was higher.…”

This study tracked change over time in sleep quantity, disturbance, and timing, and sleep's covariations with living situation, stress, social support, alcohol use, and grade point average (GPA) across four years of university in 186 Canadian students. Women slept longer as they moved through university, and men slept less; rise times were later each year. Students reported sleeping fewer hours, more sleep disturbances, and later rise times during years with higher stress. In years when students lived away from home, they reported more sleep disturbances, later bedtimes, and later rise times. Living on campus was associated with later bedtimes and rise times. Alcohol use was higher and GPA was lower when bedtimes were later. The implications of these observed patterns for understanding the correlates and consequences of university students' sleep are discussed.

“…Short sleep duration has been found to be positively associated with concurrent or future obesity in both cross-sectional and longitudinal studies [4, 5]. Moreover, insomnia, poor sleep quality and short sleep have been found to be correlated with high stress [6–8], associations that hold even after controlling for competing explanations, such as physical activities or socioeconomic status. Recently, several medical studies have demonstrated that self-reported (subjective) hours of sleep are associated with increased stress level and an elevated prevalence of obesity [9, 10].…”

Stochastic Variability in Stress, Sleep Duration, and Sleep Quality Across the Distribution of Body Mass Index: Insights from Quantile Regression

2013

Purpose This study investigates whether sleep and stress are associated with body mass index (BMI) respectively, explores whether the combination of stress and sleep is also related to BMI, and demonstrates a thorough picture of how these associations above vary across the distribution of BMI values. Methods We analyze the data from 3,318 men and 6,689 women in the Philadelphia area using quantile regression (QR) to evaluate the relationships between sleep, stress, and obesity by gender. Results Our substantive findings include: (1) high and/or extreme stress were related to roughly an increase of 1.2 in BMI even after accounting for other covariates; (2) the pathways linking sleep and BMI differed by gender; with BMI for men increasing by 0.77–1 units with reduced sleep duration, and BMI for women declining by 0.12 unit with one units increase in sleep quality; (3) stress and sleep-related variables were confounded but there was little evidence for moderation between these two; (4) the QR results demonstrate that the association between high and/or extreme stress to BMI varied stochastically across the distribution of BMI values, with an upward trend, suggesting that stress played a more important role among adults with higher BMI (i.e., BMI > 26 for both genders); and (5) the QR plots of sleep-related variables show similar patterns, with stronger effects on BMI at the upper end of BMI distribution. Conclusions Our findings indicated that having sufficient and quality sleep and reducing stress may be two intervention strategies that can be promoted among adults in Philadelphia.

“…Most previous research has focused on which personality traits are related to impaired sleeping. Neuroticism has emerged as a robust predictor of sleep quality, with people who are dispositionally stressed, depressed, anxious, and angry being shown to suffer from poor sleep [2][3][4][5][6][7]. This research has been influential both in developing models of the etiology of insomnia and in developing psychological treatments of sleep disorders [1].…”
