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.

Ultrahigh-voltage potassium-ion batteries (PIBs) with cost competitiveness represent a viable route towards high energy battery systems. Nevertheless, rapid capacity decay with poor Coulombic efficiencies remains intractable, mainly attributed to interfacial instability from aggressive potassium metal anodes and cathodes. Additionally, high reactivity of K metal and flammable electrolytes pose severe safety hazards.

Silicon is widely recognized as a promising anode material for all-solid-state batteries (ASSBs) due to exceptional specific capacity, abundant availability, and environmental sustainability. However, the considerable volume expansion and particle fragmentation of Si during cycling lead to significant performance degradation, limiting its practical application. Herein, the development of a pre-lithiated Si-based composite anode (c-LiSi) is presented, designed to address the key challenges faced by Si-based anodes, namely severe volume changes and low electrochemical stability.

Metal-organic frameworks (MOFs) are rigorously investigated as promising candidates for CO capture and conversion. MOF-on-MOF heterostructures integrate bolstered charger carrier separation with the intrinsic advantages of MOF components, exhibiting immense potential to substantially escalate the efficiency of photocatalytic CO reduction (CORR). However, the structural and compositional complexity poses significant challenges to the controllable development of these heterostructures.
