The correlation between sleep duration、sleep quality and cardiovascular disease risk factors in elderly

Objective To investigate the correlation between sleep status and cardiovascular disease risk factors in the elderly and provide reference for the prevention and treatment of cardiovascular disease. Methods From February 2018 to June 2019, 1 061 elderly people who underwent physical examination in the department of health management of our hospital were selected as research subjects, including 473 males and 588 females, aged ≥ 60 years. Subjects were given a questionnaire, physical examination, and biochemical examination. Sleep duration and sleep quality were assessed on a self-reported basis. Results The incidence rate of diabetes, hypertension and dyslipidemia in at least one diseases in sleep group <7 h and >9 h were 57.2% and 63.4% respectively, significantly higher than those in the 7-8 h group(P<0.05). Multivariable logistic regression analysis results showed that compared to sleep 7-8 h group, the sleep group <7 h, 8-9 h and > 9 h of the elderly, at least one type of diabetes, hypertension and dyslipidemia OR values were 2.493(95%CI:1.207-4.934, P<0.05), 1.093(95%CI:0.762-1.874, P>0.05) and 1.258(95%CI:1.074-2.706, P<0.05). Compared with the elderly with good sleep, the risk OR value of at least one of diabetes, hypertension and dyslipidemia in those with poor sleep was 1.817(95%CI:1.024-3.272, P<0.05). Conclusion There is a "U" relationship between the duration of sleep and cardiovascular disease risk factors in elderly people. The reduction and extension of sleep time can increase cardiovascular disease risk factors. Sleep quality is also closely related to cardiovascular disease risk factors.
