Abstract:
Objective To explore the association between the change of daily living activities and the suymtoms of depression in Chinese middle-age and elderly people.Methods People without symptoms on depression,emotional or spiritual diseases or memories related diseases in baseline survey (2011),those who were aged ≥45 years in the China Health and Retirement Longitudinal Survey (CHARLS) with two waves from 2011 to 2013 were invited to participate in this CHARLS study.Information related to demographic characteristics and health status of the subjects were collected through household-interview.Depression symptom was assessed with the Center for Epidemiological Studies of Depression (CES-D10) scale.Activities of daily living function was assessed by both Basic Activities of Daily Living (BADL) and Instrument Activities of Daily Living (IADL) scales.Symptoms of depression was compared and the differences in various BADL/IADL changing groups were analyzed with Log-rank test.Association between the changes of daily living activities and depression symptom was analyzed by Cox regression model.Results Results from the log-rank test showed that the differences of depression symptom hazard ratio were statistically significant in different BADL/IADL changing groups.Results from the Cox regression analysis showed that the BADL/IADL in the deteriorating groups was associated with the higher hazard ratio of depression symptom (P＜0.01),with the HR value (95％CI) for BADL and IADL deteriorate groups as 1.45 (1.20-1.76) and 1.64 (1.36-1.98),respectively,when comparing to the ‘stablized'group.This phenomenon appeared an urban-rural difference.Statistical significances on IADL also happened in both urban and rural areas while BADL only occurred in rurals.Conclusion There appeared an association between the change of daily living activities and depression symptom in Chinese middle-age and elderly people.Difference between IADL and BADL was also noticed between urban and rural areas.
