Abstract:

Objective To explore the weights and comprehensive indices of each field of intrinsic capacity of old adults, and the correlation between intrinsic capacity and activities of daily living (ADL).
Methods The data of 5 506 cases aged more than 60 years in the 2015 China Health and Retirement Longitudinal Study (CHARLS) were used to collect the assessment of intrinsic capacity and the measurement of ADL. The assessment of intrinsic capacity included cognition, motor, vitality, sensory and psychology; while the ADL scale included six indicators, namely dressing, bathing, eating, getting in or out of bed, going to the toilet, and controlling urine and feces.
Results A total of 1 343 cases were limited in ADL (24.4%). Women, lower education level, older age, the widowed, greater number of chronic diseases, and poorer self-rated health were the factors more likely to be limited in ADL. Principal component analysis showed that the largest weight value was in psychological domain, followed by the cognitive domain, and the lowest weight value was in the motor domain. After controlling for the effects of age, gender, living environment, economic income, education level, marriage, smoking and drinking, number of chronic diseases, and self-rated health, the Logistic regression analysis showed that low exercise capacity (OR = 0.581, 95%CI 0.501 to 0.674), depression (OR = 0.426, 95%CI 0.368 to 0.493), audile and visual impairment (OR = 0.813, 95%CI 0.699 to 0.947; OR = 0.684, 95%CI 0.578 to 0.809), overweight (OR = 1.203, 95%CI 1.014 to 1.428) and obesity (OR = 1.584, 95%CI 1.312 to 1.912) were independent risk factors for ADL limitation in older adults.
Conclusion Decrease of intrinsic capacity is a predictor for ADL limitation in older adults.
