The association of hemopexin, muscle quality, and sarcopenia in Japanese older adults with cognitive impairment: a cross-sectional study

Zeng, D., Mizutani, K., Qi, X., Asada-Utsugi, M., Wu, B., Kawasaki, T., Akiguchi, I., & Kinoshita, A. (2025). BMC Geriatrics, 25(1). 10.1186/s12877-025-05977-8
Abstract
Abstract
Objective: To examine the cross-sectional associations of hemopexin, muscle quality, and sarcopenia status with cognitive function among older Japanese adults with cognitive impairment, and to explore the potential sex-specific differences. Methods: A total of 580 older adults (372 women, 208 men; mean age 83.3 ± 6.2 years) who presented with cognitive impairment at the Kyoto Dementia Comprehensive Center between 2018 and 2022 were enrolled. Cognitive function was assessed using the Mini-Mental State Examination (MMSE). Hemopexin level was measured by enzyme-linked immunosorbent assay. Muscle quality was evaluated via phase angle (PhA) and grip strength, and sarcopenia status was defined using the Asian Working Group for Sarcopenia criteria. Multiple linear regression models, including sex-stratified analyses, were conducted to determine the relationships of these variables with MMSE scores. Results: Higher hemopexin levels (β = 1.19, p = 0.017), PhA (β = 0.59, p = 0.005), and grip strength (β = 0.14, p < 0.001) were independently associated with better MMSE scores, whereas sarcopenia was negatively linked to MMSE scores (β = − 2.28, p < 0.001). Notably, sex-stratified models indicated that hemopexin positively predicted MMSE scores in men but not in women; meanwhile, sarcopenia showed a stronger negative impact in women. Educational attainment also displayed a significant positive association with cognitive performance in both sexes. Conclusions: In this cross-sectional study of older Japanese adults with cognitive impairment, hemopexin levels and muscle quality emerged as important correlates of cognitive function, particularly in men, while sarcopenia was negatively linked to cognition.

Different Sources of Social Capital and Loneliness Among Adults in Shanghai, China: Exploring Sex Differences

Qi, X., Pei, Y., Li, G., Tang, W., Hall, B. J., & Wu, B. (2025). Journal of Community & Applied Social Psychology, 35(2). 10.1002/casp.70089
Abstract
Abstract
Loneliness is a global health concern that negatively impacts physical/mental health. Social capital, encompassing resources from social networks, may protect against loneliness. We investigated the association between different sources of social capital and feelings of loneliness and examined whether these associations differ by sex. An online survey of 3220 Shanghai residents (mean age 34.5 years, 48.5% females) was conducted in 2022, Shanghai, China. We assessed bonding and bridging social capital using the revised 8-item Personal Social Capital Scale (PSCS) and used the revised three-item UCLA Loneliness Scale to measure loneliness. Multivariable linear regression analysis results suggest that both bonding (β coefficient: −0.152; SE: 0.035) and bridging social capital (β coefficient: −0.131; SE: 0.036) were significantly associated with lower loneliness, adjusting for sociodemographic characteristics, health conditions, and COVID-19-related factors. Notably, the mitigating effect of bonding social capital on loneliness was more pronounced in females, as indicated by significant interactions between sex and bonding social capital. Our study findings indicated that social capital serves as a protective factor against loneliness for Chinese adults, with bonding social capital having a stronger effect among females. Policies and interventions strengthening bonding social capital may facilitate reduced feelings of loneliness among Chinese, especially females.

Psychological distress in Asian American informal caregivers: an analysis by disaggregated ethnic groups

Qi, X., Wang, K., Pei, Y., Ðoàn, L. N., Yi, S. S., & Wu, B. (2025). Ethnicity and Health, 30(2), 232-253. 10.1080/13557858.2024.2430287
Abstract
Abstract
Background: Despite Asians being the fastest-growing ethnic group in the US, most studies have focused on Asian Americans as an aggregate racial/ethnic group. The burden of mental health problems is increasing among caregivers due to population aging, yet little is known about the distress experienced by Asian caregivers when examined by disaggregated ethnic groups. Methods: Using 2019–2020 California Health Interview Survey data, we examined disparities in psychological well-beings between non-Hispanic White and Asian American adult caregivers, with an emphasis on understudied Asian ethnic groups. Psychological distress was measured using the Kessler 6 scale, with scores ≥6 indicating mental distress and ≥13 indicating serious mental illness. Multivariable logistic regression adjusted for socio-demographics, physical health, caregiving relationship, intensity of care, and care recipients’ characteristics. Results: The study included 8,722 caregivers (mean age, 58.7 years; 61.3% women; 14.1% Asian [379 Chinese, 260 Filipino, 167 Japanese, 138 South Asian, 105 Korean, 101 Vietnamese, 78 other Asian], 85.9% White). Overall, 26.8% had mental distress, and 8.5% had serious mental illness. Compared to White caregivers, Korean American caregivers had higher odds of mental distress (Odds Ratio [OR], 2.37; 95% CI, 1.47–3.82) and serious mental illness (OR, 2.15; 95% CI, 1.17–3.92), while Chinese (OR, 0.72; 95% CI, 0.55–0.95) and Japanese (OR, 0.67; 95% CI, 0.45–0.99) American caregivers had lower odds of mental distress. Korean American caregivers had the highest prevalence of mental distress (43.1%) and serious mental illness (15.3%), compared with White and other Asian American caregivers. Conclusion: Disaggregating data reveals significant mental health disparities among ethnic subgroups of Asian American caregivers. Tailored resources should address the distinct needs of ethnic subgroups of Asian American caregivers, considering language barriers, acculturation, and cultural norms that may exacerbate psychological distress.

Sui, J., Wu, B., Zheng, Y., Mo, Z., Dong, Q., Ðoàn, L. N., Yi, S. S., & Qi, X. (2025). Obesity Medicine, 53. 10.1016/j.obmed.2024.100573
Abstract
Abstract
AIMS: Compare racial/ethnic disparities in the prevalence of non-obese type 2 diabetes (T2D) and the proportion of non-obese individuals among T2D patients.METHODS: This cross-sectional study used ICD-9/10 codes to ascertain T2D. Participants were classified as non-obese by BMI (<25 kg/m2 for normal weight; <23 kg/m2 for Asian Americans), waist circumference (<102 cm for males, <88 cm for females), and waist-to-hip ratio (<0.9 for males, <0.85 for females). The statistical analysis used marginal standardization of predicted probabilities from multivariable logistic regression to calculate the prevalence.KEY RESULTS: Among 276,736 participants (mean age 51.7, 61.2% female), non-obese T2D prevalence varied: 6.85% (BMI), 4.17% (waist circumference), 3.63% (waist-to-hip ratio). Asian participants had the highest prevalence of normal-weight T2D (2.70% vs. 1.92% in White, OR 1.44, 95% CI: 1.22-1.69) and non-obese T2D by waist circumference (8.04% vs. 3.36%, OR 2.61, 95% CI: 2.35-2.89). Black participants had the highest prevalence using waist-to-hip ratio (5.37% vs. 2.91%, OR 1.91, 95% CI: 1.80-2.03).CONCLUSION: Asian Americans showed higher non-obese T2D prevalence by BMI and waist circumference, while Black adults had higher prevalence by waist-to-hip ratio, suggesting different fat distribution patterns.
