Correlation between sleep duration and limited ability of activities of daily living in middle-aged and elderly people
Objective To explore the correlation between sleep duration and activities of daily living(ADL)limitation in middle-aged and elderly people,and analyzed the differences from gender and age dimensions,so as to help middle-aged and elderly people identify the optimal sleep duration,develop good sleep habits,and provide evidence or reference for de-veloping strategies to improve ADL.Methods A total of 7 702 subjects aged 45 years and above were included in the study using data from CHARLS database in 2015.The sleep duration of the subjects was assessed by questionnaires to determine whether there was ADL restriction.Multivariate logistic regression model was used to explore the correlation between sleep duration and ADL restriction,and the differences were analyzed from gender and age dimensions.Results Among all sub-jects,2 236(29.05％)and 2 939(38.2％)patients with limited basic activities of daily living(BADL)and instrumental activ-ities of daily living(IADL)were limited,respectively.After adjusting for all covariates,the risk of BADL restriction OR I-ADL restriction(except for elderly women)in those with short sleep duration(＜6 h)were higher than those in the control group(7～＜8 h),the difference were statistically significant(P＜0.05),while the risk of BADL restriction in elderly women with 6～＜7 h sleep duration(OR=1.51,95％CI:1.02-2.24)was higher than that of control group(7～＜8 h),and the differ-ence was statistically significant(P＜0.05).The IADL restriction risk(OR=1.72,95％CI:1.11-2.67)was higher in elderly men than in control group(7-＜8 h),and the difference was statistically significant(P＜0.05).Conclusion There is a corre-lation between sleep duration and ADL restriction in middle-aged and elderly people,and there are gender and age differ-ences.In addition,sleep duration that is too short or too long increases the risk of ADL limitation in some people.
