Relationship between Daytime Napping,Nocturnal Sleep and Cardiovascular-metabolic Comorbidities
Objective:To explore the relationship between sleep status and the risk of cardiovascular-metabolic comorbidity in Chinese population age over 60 years old.Methods:Based on data from the China Health and Retirement Longitudial Study(CHARLS)in 2011 and 2015,participants without cardiovascular-metabolic comorbidities at baselineage(age over 60 years old)who participated in the 2015 follow-up were selected as subjects.Multivariate Logistic regression model was used to investigate the association between sleep conditions(daytime napping time,daytime napping duration,nocturnal sleep time,nocturnal sleep duration,sleep quality)and the risk of cardiovascular-metabolic comorbidities.Subgroup analysis of hypertension,dyslipidemia,diabetes,depression,and heart disease were conducted to explore the relationship between daytime napping duration and cardiovascular-metabolic comorbidities.Results:A total of 6 829 participants were included.Multivariate Logistic regression analysis showed that compared with participants without daytime napping(0 min),the risk of cardiovascular metabolic comorbiditiseincreased in participants with daytime napping(≥30 min)(OR=1.40,95％CI 1.08-1.82,P＜0.05).Especially in hypertension(OR=1.43,95％CI 1.03-1.98,P＜0.05),dyslipidemia(OR=1.53,95％CI 1.08-2.16,P＜0.05),and non-diabetes(OR=1.37,95％CI 1.02-1.83,P＜0.05).Compared with normal nocturnal sleep(7～9 h),long nocturnal sleep(＞9 h)was associated with a lower risk of cardiovascular-metabolic comorbidities(OR=0.36,95％CI 0.14-0.90,P＜0.05).Sleep quality was not associated with the risk of cardiovascular-metabolic comorbidities(P＞0.05).Conclusion:Long daytime napping(≥30 min)might increase the risk of cardiovascular-metabolic comorbidities and long nocturnal sleep(＞9 h)might decrease the risk of cardiovascular-metabolic comorbidities in Chinese population age over 60 years old.
