N2 - Objectives: The World Health Organization's Integrated Care for Older People (ICOPE) framework launched in 2019 is used to assess the intrinsic capacity of older individuals. Older women may face greater socioeconomic disadvantages, which can impact their physical and mental well-being. Therefore, we examined sex differences in intrinsic capacity and the influence of socioeconomic status. Methods: We conducted a cross-sectional study in Tainan, Taiwan, recruiting 1,268 adults aged 60 or older in 2022. The ICOPE screening assessed cognitive decline, limited mobility, malnutrition, visual impairment, hearing loss, and depressive symptoms. Intrinsic capacity scores ranged from 0 to 6 and were categorized as impairment (1 or higher) or no impairment (0). Binary logistic regression models were used to analyze sex differences in intrinsic capacity, adjusting sequentially for demographics, lifestyle, and socioeconomic factors. Results: The prevalence of intrinsic capacity impairment was 34 %. Women had significantly higher odds of intrinsic capacity impairment (women vs. men, odds ratio [OR] = 1.39, 95 % CI = 1.10–1.75). After sequentially adjusting for demographic characteristics, lifestyle, and socioeconomic factors, the ORs were 1.46 (95 % CI = 1.12–1.90), 1.69 (95 % CI = 1.23–2.31), and 1.24 (95 % CI = 0.88–1.73), respectively. Stratified analyses showed that higher odds of impairment in women than in men was evident only in the financially dependent group (P for interaction = 0.059). Conclusions: Older women in Taiwan have poorer intrinsic capacity than men, a disparity largely attributable to women's lower socioeconomic status. Strategies to promote healthy aging among women from disadvantaged socioeconomic backgrounds may help mitigate this sex difference in intrinsic capacity.
