摘要

On the basis of increasing evidence that short sleep duration results in metabolic changes that may contribute to the development of obesity, insulin resistance, diabetes and cardiovascular disease. We reviewed epidemiological studies associating short sleep with increased body mass index (BMI) that have shown an increased risk of weight gain and obesity in children and young adults who are short sleepers. Altogether, the evidence points to a possible role of decreased sleep duration in the current epidemic of obesity. The purpose of this study was to use Pittsburgh Sleep Quality Index to investigate the sleep duration, sleep quality and BMI in university students. The participants included 600 college students (255 male students with mean age 19.3±0.9 years and 345 female students with mean age 19.2±0.7 years). All data were processed by SPSS for windows 18.0 system. The investigated values were presented by descriptive statistics method chi-square test and Scheffe post-hoc, were considered to be significant if the p value was ＜.05. Results revealed that 52.3% reported PSQI scores above the clinical cutoff of 5. A better Global Score (PSQI≦5) with sleep ＞7 h/night is 75.4% and worse Global Score (PSQI＞5) with sleep ＜6 h/nigh is 66.3% in all subjects. Male students with sleep ＞7 h/night compared to sleep ＜6 h/nigh, are significant different in the sleep score, sleep efficiency, subjective sleep quality and daytime function. In addition, the female students are more significant different in BMI and drug medication. We concluded that sleep duration may be related to the BMI and sleep quality in university students and at least 7 hours of sleep will have a better quality of sleep.
