Health Trajectories of Older Chinese Adults: Gender Disparities and Cohort Differences

This study investigates the gender disparities and cohort differences in the health trajectories of older Chinese adults. Drawn on a nationally representative dataset from the 2008-2018 Chinese Longitudinal Healthy Longevity Survey, this paper uses a growth-curve model to identify the health trajectories of older adults in functional limitations, chronic diseases, depressive symptoms and cognitive skills. Older women are found to have slightly fewer functional limitations than older men at an earlier age; however, this gap is reversed later because of women's higher deterioration rate in physical function. Compared to men, older women have more chronic diseases at younger ages, but this trend is changed after age 90 years due to a faster decline rate in chronic diseases for women. The gender gap in the depressive symptom trajectories narrows with age, whereas the gap in the trajectories of cognitive skills widens. The cohort differences favouring later-born cohorts decrease with age in the trajectory of functional limitations. The latest cohort born in 1940 or after has the fastest increase in chronic diseases and depressive symptoms among all the cohorts. These results are further verified using the random-effect model and pooled ordinary least squares. Policymakers should promote gender equality and reduce cohort differences to achieve the national goal of "Healthy China".
