Gender Disparities in Frailty and Its Decomposition Among Chinese Older Adults

To identify the evidence of gender disparities in frailty and explore the factors contributing to male-female differences. A longitudinal study. A total of 24,429 older adults (60+) were enrolled. Frailty was assessed by frailty index and frailty risk based on Rockwood's cumulative deficit frailty index. OLS and logistic regression models were conducted, with Oaxaca-Blinder and Fairlie decomposition methods to further analyse the factors contributing to gender disparities in frailty. The paper used four waves of the China Health and Retirement Longitudinal Study from 2011 to 2018, a nationwide survey organised by the National Development Institute of Peking University. Women had higher frailty status than men, with more pronounced increases. Among the factors, education has the most significant association with frailty gender disparities. The contribution of individual characteristics, particularly education, to gender disparities in frailty appeared to diminish over time, while the contribution of family and regional factors remained relatively stable, and the contribution of institutions was deemed inadequate. The frailty in Chinese older adults is generally on the rise with continuously expanded gender disparities. It is crucial to consider the contributing factors to frailty in older adults for effective prevention and intervention strategies. Additional gender-specific geriatric care policies are needed in order to address gender inequality in health. The findings of this study highlight the prevalence of increasing gender disparities in frailty and identify that the level of education, per capita annual household income as well as marital status are the most significant factors contributing to the gender gap. Those findings provide policy implications for healthcare nursing service from a gender-specific perspective in order to achieve health equity. This study has adhered to the STROBE guideline. No Patient or Public Contribution. WHAT DOES THIS PAPER CONTRIBUTE TO THE WIDER GLOBAL CLINICAL COMMUNITY: This study provided implications on gender-specific geriatric care nursing services. The study highlighted the importance of focusing on frailty and its gender disparities in geriatric clinical nursing.
