Deteriorated sleep quality and influencing factors among undergraduates in northern Guizhou, China

Abstract

Background The sleep quality of undergraduates is considerably worse than that in general population, a cross sectional study was conducted to evaluate sleep quality and identify related factors. Methods All participants from the freshmen to senior were recruited by the stratified cluster sampling from December 1, 2018 to January 12, 2019. The questionnaire used in this research was primarily composed of three sections: demographic characteristics, Pittsburgh Sleep Quality Index (PSQI) questionnaire and influencing factors of sleep quality. The data were analyzed using SPSS 18.0. Results A total of 1,063 valid questionnaires were collected. Among them, 53.7% subjects suffered poor sleep quality. PSQI general score was 5.94 ± 2.73. There were significantly differences in sleep quality in sex, majors and grades. The survey reported that women suffered worse sleep quality than that of men, and medical students suffered worse sleep quality than non-medical students. Meanwhile, it also found that freshmen had better sleep quality than that of sophomores and juniors, sophomores suffered worst sleep quality. The logistic regression analysis showed that bad physical condition (OR (Odds ratio): 2.971 (2.034∼4.339)) and smoking (OR: 1.754 (1.258∼2.446)) were associated with poor sleep quality in males. However, more factors associated with poor sleep quality among females were found, including noisy dormitory environment (OR: 2.025 (1.354-3.030)), skipping breakfast more times per week (OR: 1.332 (1.031∼1.721)), drinking coffee before sleep (OR: 2.111 (1.155∼3.861)), playing with mobile phones for more than 45 minutes before sleep (OR: 1.745 (1.210∼2.515)), more time spent playing games per day (OR: 1.347 (1.048∼1.730)), bad physical condition (OR: 2.507 (1.797-3.497)), and severe academic stress (OR: 1.561 (1.126-2.166)). Conclusion About half of college students experienced poor sleep, and poor sleep quality was prevalent in women, medical students, and sophomores. Moreover, there were more risk factors associated with the poor sleep quality of women than with men. Health policymakers should fully consider these factors in improving the sleep quality of college students.

Study on lifestyle habits affecting sleep disorders at the undergraduate education stage in Xuzhou City, China

“…Meanwhile, the incidence of sleep disorders in undergraduate student population is high due to their poor lifestyle habits ( Falavigna et al, 2011 ). A survey in Guizhou, China, showed that about 53.7% of college students experienced poor sleep ( Zhou et al, 2022 ). Sleep disorders among undergraduates have become a common and prominent harmful public health problem.…”

Prevalence and related factors of sleep quality among Chinese undergraduates in Jiangsu Province: multiple models' analysis

“…However, newer models of cell phones currently have the ability to turn off blue light, and this study did not investigate the condition with blue light turned off, so this finding may have limitations. A gender-specific study (Zhou et al, 2022 ) found that smoking was a risk factor for poor sleep quality among males, and noisy dormitory and academic pressure were risk factors for poor sleep quality among females. A study on college students of Jilin Province (Li Y. et al, 2020 ) found that drinking, academic pressure, and relationships with classmates were risk factors for poor sleep quality.…”

“…Unfortunately, a significant number of undergraduates are experiencing poor sleep quality. In some provinces of China, the proportion of undergraduates with poor sleep quality has crossed more than 30.0%; for example, the proportions in Jilin, Guizhou, and Hong Kong were 33.8%, 53.7%, and 57.5%, respectively (Suen et al, 2008 ; Li Y. et al, 2020 ; Zhou et al, 2022 ). Sleep quality among undergraduate students has also been poor in other countries such as Ethiopia (57.5%) and India (51.0%) (Lemma et al, 2012 ; Ghrouz et al, 2019 ).…”

“…Another study found that being a freshman, alcohol use, gambling, exercising for more than 30 min a week on <1 day, satisfaction with parental love, and harmonious relationship with classmates were risk factors, while no learning pressure, never having self-injurious behaviors, and harmonious family relationship were protective factors (Li Y. et al, 2020 ). A gender-specific study in China identified some risk factors for poor sleep quality that were related to weak physical condition and smoking in males, while noisy dormitory, skipping breakfast, drinking coffee, playing games, bad physical condition, and severe academic stress led to poor sleep quality in females (Zhou et al, 2022 ). A cluster randomized-controlled trial in China showed that good dormitory sleep environments could maintain good sleep quality (Li et al, 2022 ).…”

Sleep quality of undergraduates in Fujian and its influencing factors : a cross-sectional study

“…Sleep quality can cause physiological and psychological changes in college students, and they are easy to lead to related diseases in the long run.The literature reported that there were close associations between poor sleep status and illness, including hypertension 6 , diabetes 7 and so on 8 .Accumulating evidence shows that poor sleep status is also related to mental health,especially anxiety 9 and depression 10 .The profound in uence of sleep disorders on college students has attracted wide attention from students themselves and the society.Existing studies have reported that there are various factors can affect the sleep quality of college students,including individual characteristics,behavioral and lifestyle factors and physical and mental health factors [11][12][13] . Thus, by investigating the sleep status of college students and analyzing the in uencing factors, we can provide feasible intervention measures to promote the physical and mental health of college students.…”
