Insomnia is a major public health problem affecting older people. This study aimed to investigate the prevalence and clinical risk factors of insomnia in a representative sample of Chinese elderly (≥ 60 years) in Chongqing.
A cross-sectional study based on comprehensive geriatric assessment was conducted from January 2013 to February 2014. A questionnaire on sleep status was provided to each patient and insomnia was assessed according to the Diagnostic and Statistical Manual of Mental Disorders 4th edition criteria. A multivariate logistic regression model was used to illustrate risk factors correlated with insomnia.
Of the total 597 participants, 55.4% suffered from insomnia. The prevalence of insomnia in men and women was 48.2% and 63.2%, respectively. Coronary heart disease, dizziness, chronic pain, anorexia, malnutrition, depression and cognitive decline were identified as risk factors associated with insomnia. Hypertension, diabetes, hyperlipidaemia, headache, age and education level were not observed to be significantly associated with insomnia.
Insomnia is highly prevalent among the elderly in Chongqing, and shows a positive correlation to coronary heart disease, dizziness, chronic pain, anorexia, malnutrition, depression, cognitive impairment. Moreover, women are more likely to experience insomnia than men.
