N2 - Objective: To examine time-dependent predictors of functional impairment in olderadults in Europe longitudinally.Methods: Data were derived from the Survey of Health Ageing, and Retirement inEurope (2004-2013). Functional impairment was assessed by using activities of dailyliving (ADL) and instrumental activities of daily living (IADL) indices. Fixed effectsregressions were used to estimate the effects of sociodemographic factors (age,marital status, living situation, and income deciles (median split)), lifestyle factors(smoking status and alcohol consumption per week), depression, cognitive functionand chronic diseases on the outcome variables.Results: Longitudinal regressions revealed that functional impairment increasedsignificantly with age, the occurrence of depression, cognitive impairment, the numberof chronic conditions, and less than daily alcohol consumption in the total sample andin both sexes. Moreover, the onset of smoking and living without a spouse/partner inhousehold increased functional impairment in the total sample. The effect ofdepression on functional impairment was significantly more pronounced in men.Conclusion: Our findings highlight the relevance of changes in age, depression,cognitive function, smoking and chronic diseases for functional impairment. Sinceparticularly depression and smoking may be avoidable, developing strategies toprevent depression or stop smoking might be useful approaches to postpone functionalimpairment in older adults.
