Association Between Sleep Hygiene and Sleep Quality in Medical Students

Abstract

The aim of this study was to determine whether subjective sleep quality was reduced in medical students, and whether demographics and sleep hygiene behaviors were associated with sleep quality. A Web-based survey was completed by 314 medical students, containing questions about demographics, sleep habits, exercise habits, caffeine, tobacco and alcohol use, and subjective sleep quality (using the Pittsburgh Sleep Quality Index). Correlation and regression analyses tested for associations among demographics, sleep hygiene behaviors, and sleep quality. As hypothesized, medical students’ sleep quality was significantly worse than a healthy adult normative sample (t = 5.13, p < .001). Poor sleep quality in medical students was predicted by several demographic and sleep hygiene variables, and future research directions are proposed.

The Epidemiology of Sleep Quality, Sleep Patterns, Consumption of Caffeinated Beverages, and Khat Use among Ethiopian College Students

“…No statistically significant association was noted between caffeine consumption and other sleep quality parameters. Our findings are in general agreement with some previous studies [27, 28]. For instance Brick et al [27], in their study among 341 US medical students, found no significant association between caffeine use and poor sleep quality.…”

“…Our findings are in general agreement with some previous studies [27, 28]. For instance Brick et al [27], in their study among 341 US medical students, found no significant association between caffeine use and poor sleep quality. Similarly, Lund et al [28] in a large survey of a Midwestern university found caffeine consumption to be a nonsignificant predictor of sleep quality.…”

Impacto do etanol e consumo de café na qualidade de sono de acadêmicos de medicina

“…A vida acadêmica em faculdades e universidades é marcada por períodos de mudança, no qual a maioria dos jovens deve aprender a lidar com coerções sociais e inúmeras situações de estresse longe dos pais. A maioria das mudanças no estilo de vida dos estudantes inclui dieta não balanceada, uso de álcool, uso de tabaco, comportamentos sexuais inseguros e redução da carga horária de sono, o que pode levar a um detrimento do bem-estar dos estudantes 24,25 . 15 .…”

Caffeine Use among Active Duty Navy and Marine Corps Personnel

“…Epidemiological studies that have used convenience samples to examine associations between caffeine and sleep duration or sleep quality have found conflicting results [47,53,54,55,56]. On the other hand, investigations using randomized, population-based samples have shown shorter sleep duration is associated with higher caffeine consumption [32,57,58].…”
