Association between sleep quality and lifestyle habits of college students

Sleep quality in college students

Abstract

The aim of this study was to verify sleep quality, as well as its determinants, among college students of a private university in Brazil. The sample consisted of 303 college students. Sleep quality was assessed by questionnaire, and other variables included current physical activity, previous physical activity, sedentary behavior, body mass index, alcohol consumption, smoking, and employment. We found a significant association between bad sleep quality and body mass index (p-value = 0.001), alcohol consumption (p-value = 0.001), smoking (p-value = 0.005) and employment (p-value = 0.030). However, having a job was considered a protective factor for bad sleep quality (OR = 0.66 [0.40;0.98]), regardless of other factors. College students present a high prevalence of altered sleep, having as determinants alcohol consumption, smoking, overweight, and obesity. On the other hand, being employed was shown to be a protective factor for bad sleep quality.
