Sleep disorders and their associations with anxiety and depression among male detoxification patients under compulsory isolation in Yunnan Province, China

Background This study aimed to evaluate the prevalence of sleep disorders and examine its associations with anxiety and depression symptoms among male detoxification patients under compulsory isolation in Yunnan Province, China. Methods Data were collected from a cross-sectional health interview and examination survey of 1,021 drug users among male detoxification patients under compulsory isolation in China. Sleep disorders, anxiety, and depressionsymptoms were evaluated using the Pittsburgh Sleep Quality Index (PSQI), Zung’s Self-Rating Anxiety Scale (SAS), and the Self-rating Depression Scale (SDS), respectively. Sleep disorders and anxiety and depression symptoms were evaluated using multivariate logistic regression. Results The prevalence of sleep disorders, anxiety, and depression symptoms were 73.0%, 8.9%, and 6.9%, respectively. Ethnic minorities, participants with a lower level of education, and participants with poor health status by self-assessment had a higher prevalence of sleep disorders than their counterparts ( P <0.05). Participants who consumed ephedrine had the highest prevalence of sleep disorders ( P <0.05), while those who consumed heroin had the highest prevalence of anxiety symptoms ( P <0.001). Multivariate logistic regression analysis uncovered that those with sleep disorders had a greater probability of having anxiety (OR=2.310; 95% CI: 1.116 to 4.783) and depression symptoms (OR=4.683; 95% CI: 1.664 to 13.180). Conclusions Male detoxification patients under compulsory isolation in China experience a high level of sleep disorders, and their sleep disorders are significantly associated with anxiety and depression symptoms. Improving sleep quality may reduce the prevalence of anxiety and depression symptoms in the male detoxification patient population.
