Correlation of insomnia with perceived stress in college students
Objective To investigate the prevalence of insomnia in college students and analyze the correlation between insomnia and perceived stress. Methods A cluster sampling method was used to investigate the prevalence of insomnia and stress levels in 3702 college students using Insomnia Severity Index (ISI) and Perceived Stress Scale-10 (PSS-10). Results Insomnia was detected in 31.4％ of the college students, and the symptoms were more severe in male students (t=2.047, P=0.041) and in those with poorer family economic conditions (F=20.423, P<0.001). Insomnia was positively correlated with perceived stress, perceived distress, and perceived coping ability, with correlation coefficients of 0.42, 0.38, and 0.31, respectively (P<0.001). The students with higher levels of perceived stress had higher insomnia scores (F=203.03, P<0.001) and higher detection rate of insomnia (x2=359.784, P<0.001), and those with moderate or severe insomnia also had higher levels of perceived stress (F=293.569, P<0.001). The types of perceived stress among college students included incontrollable (15.3％), nervous (8.3％), vulnerable (23.0％) and the relaxed types (53.5％). The incontrollable type was associated with the highest insomnia scores, followed by the nervous type and susceptible type, and the relaxed type had the lowest insomnia scores (F=185.969, P<0.001). The prevalence rates of insomnia in students with the 4 types of perceived stress were 57.3％, 43.3％, 39.3％, and 18.7％, respectively (x2=368.876, P<0.001). Conclusion There is a close correlation between perceived stress and insomnia, and identification of the high-risk population for insomnia from the perspectives of perceived stress level and perceived stress type can facilitate the management and prevention of insomnia.
