Wu, B., & Zhu, Z. (2025). Nursing Outlook, 73(1). 10.1016/j.outlook.2024.102343

Abstract

Abstract

Ensuring equitable care and health outcomes for all populations is essential in nursing science. However, achieving health equity in nursing science necessitates a multifaceted approach to address the complex factors influencing health disparities. This paper presented the keynote address delivered at the Advanced Methods Conference hosted by the Council for Advancement of Nursing Science in 2023. We identified critical gaps in health equity within nursing science, emphasizing the need for innovative recruitment strategies, comprehensive data analysis, and targeted dissemination efforts. This paper underscores the importance of equity in artificial intelligence research, highlighting issues such as biases in machine learning models and the underrepresentation of minoritized groups. Bridging the current gaps in health equity research within nursing science requires a systematic and forward-thinking approach.

Xu, Z., Zhao, D., Mao, W., Wang, J., Yang, Z., Zheng, Y., & Wu, B. (2025). Aging and Health Research, 5(3). 10.1016/j.ahr.2025.100241

Abstract

Abstract

Background: With China's aging population and rising prevalence of chronic conditions, it is crucial to understand the factors shaping aging attitudes. Satisfaction with the neighborhood physical environment may play an important role, particularly among those with chronic health issues. To examine the association between neighborhood physical environment satisfaction and aging attitudes among older Chinese adults, and to explore differences across groups with and without chronic conditions. Methods: We analyzed data from 11,395 participants aged 60 and above from the 2020 China Longitudinal Aging Social Survey (CLASS). Stratified multiple regression analyses were conducted, comparing subgroups with chronic conditions (n = 8405, 73.76 %) and without chronic conditions. Results: Among participants with chronic conditions, higher satisfaction with road conditions (β = 0.382, P = 0.001), environmental sanitation (β = 0.286, P = 0.007), and road/street lighting (β = 0.288, P = 0.005) was significantly associated with more positive attitudes toward aging. No significant associations were found among participants without chronic conditions. Conclusions: Age-friendly neighborhood environments are important for promoting positive aging attitudes, particularly among older adults living with chronic conditions. These findings offer valuable insights for policymakers, researchers, and service providers aiming to support healthy aging in rapidly aging societies like China.

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.

Ma, C., Wu, B., & Brody, A. A. (2025). Journal of the American Medical Directors Association, 26(5). 10.1016/j.jamda.2025.105539

Abstract

Abstract

Objectives: Home health care (HHC) plays a pivotal role in serving millions of US adults aging in place. Although the HHC population is growing rapidly in both size and diversity, driven by an aging US population and a changing demographic profile, there are increasing concerns of equity in HHC, particularly regarding how vulnerable populations are affected under current HHC practices. The purpose of this study was to examine the variations in accessing high-quality HHC in racial and ethnic minority groups and persons living with dementia. Design: Cross-sectional, secondary analysis. Setting and Participants: Older adults who received HHC in 2016 from agencies with a star rating of overall care quality from the Home Health Compare program. Methods: Start of care data from the 2016 HHC Outcome and Assessment Information Set was linked to Master Beneficiary Summary File, Home Health Compare, and Provider of Services file to address the aim. Multinomial regressions were used in analysis when risk-adjusting for individual and agency characteristics. Results: Our risk-adjusted estimates, based on data from 574,682 older adults aged ≥65 years served by 8634 HHC agencies nationwide (2290 offering high-quality care, 4023 providing moderate-quality care, and 2321 delivering low-quality care), revealed significant disparities. Non-Hispanic Blacks (relative risk ratio, 0.62; 95% CI, 0.61–0.64) and Hispanics (relative risk ratio, 0.72; 95% CI, 0.70–0.74) were significantly less likely to receive care from high-quality agencies. Additionally, having dementia exacerbated disparities in accessing high-quality HHC between racial and ethnic minorities and white Americans. Conclusions and Implications: Racial and ethnic minority individuals face significant disadvantages in accessing high-quality HHC, with persons living with dementia from these groups being the most disadvantaged. Further research is warranted to investigate the referral and admission processes for HHC. Our findings highlight the need for actions from clinicians and policymakers to tackle potential biases in the aforementioned care processes.

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.

Qi, X., Tan, C., Luo, H., Plassman, B. L., Sloan, F. A., Kamer, A. R., Schwartz, M. D., & Wu, B. (2025). Journal of Public Health Dentistry. 10.1111/jphd.70000

Abstract

Abstract

Objectives: Edentulism and diabetes mellitus (DM) are frequently seen among older adults. However, the joint effect of edentulism and DM on mortality was understudied. We aim to examine the joint effect of edentulism and DM on all-cause mortality and to what extent the joint effect varies by race/ethnicity. Methods: Analysis of US Health and Retirement Study (HRS) data (2006–2018) included 11,813 non-Hispanic Whites, 2216 non-Hispanic Blacks, and 1337 Hispanics aged ≥ 50 years old. Mortality data came from the National Death Index or HRS surveys. Edentulism was self-reported and DM was determined by self-reported diagnosis, medication use, or glycosylated hemoglobin. Cox proportional-hazard models with inverse probability treatment weighting were applied. Results: During mean follow-up of 9.6 years, 2874 Whites, 703 Blacks, and 441 Hispanics died. DM was associated with higher mortality across all groups (Whites: HR = 1.43, 95% CI = 1.25–1.64; Blacks: HR = 1.62, 95% CI = 1.28–2.04; Hispanics: HR = 1.46, 95% CI = 1.07–1.99). However, edentulism predicted higher mortality only in Whites (HR = 1.65, 95% CI = 1.51–1.80). Having both conditions showed highest mortality risk in all groups (Whites: HR = 2.31, 95% CI = 1.56–3.42; Blacks: HR = 1.94, 95% CI = 1.45–2.59; Hispanics: HR = 1.77, 95% CI = 1.16–2.70), with a significant additive interaction observed only in Whites (relative excess risk due to interaction = 0.22, p < 0.05). Conclusions: DM and edentulism pose an additive risk for mortality in Whites, and there are racial/ethnic differences in edentulism-related mortality.

Relationship between depression and oral microbiome diversity: analysis of NHANES data (2009–2012)

Qiu, X., Xu, T., Huang, Y., Wei, C., Wang, L., & Wu, B. (2025). BMC Oral Health, 25(1). 10.1186/s12903-025-06274-x

Abstract

Abstract

Background: While the association between the gut microbiome and depression is well studied, the association between the oral microbiome and depression is less well characterized. Methods: This cross-sectional study analyzed the association between depression and diversity of oral microbiome using data from the 2009–2012 National Health and Nutrition Examination Survey (NHANES). The gene sequencing of 16S ribosomal RNA was adopted for the profiling of oral microbiome. Alpha diversity, quantified by the observed number of amplicon sequence variants (ASVs), and beta diversity, assessed using Bray–Curtis dissimilarity, were evaluated to represent oral microbiome diversity. Depressive symptoms were measured by the Patient Health Questionnaire-9 (PHQ-9) scale, with alpha diversity as the primary predictor. Weighted logistic regression was employed to examine the relationship between depression and microbial alpha diversity. Threshold effect analysis was performed to explore potential nonlinear relationships between the observed ASVs and depression. Subgroup analysis indicated that smoke, excessive alcohol consumption, and oral treatment influenced the association between oral microbiology and depression, with interaction effects observed across gender and racial groups. Beta diversity differences were evaluated using Bray–Curtis dissimilarity and visualized via non-metric multidimensional scaling (NMDS). Results: A total of 15,018 participants were included, with an average age of 42.25 ± 15.2 years. In the fully adjusted model, the alpha diversity of oral microbiome was significantly negatively correlated with depression (OR = -0.51, 95% CI: -0.79—-0.23, P = 0.003). Threshold analysis also revealed a nonlinear association in this relationship, with a significant inflection point as Log10ASVs of 2.32. Furthermore, beta diversity of the oral microbiome differed significantly between the normal and depression groups (p = 0.001). Sensitivity analyses showed that the relationship between depression and oral microbial diversity observed in this research was particularly pronounced among non-Hispanic Whites (OR = 0.16, 95% CI: 0.07–0.35) and men (OR = 0.14, 95% CI: 0.06–0.30). Additionally, significant differences in oral microbiome beta diversity were observed between the normal and depression groups (p = 0.001). Conclusions: The findings suggest that the diversity of oral microbiome is negatively correlated with depressive symptoms. Hence, oral dysbiosis may serve as a therapeutic target or biomarker of depression. However, the underlying mechanisms require further investigation.

Social context matters: Neighborhood environment as a moderator of the longitudinal relationship between edentulism and cognitive function among older adults in the United States

Liu, R., Qi, X., Mao, W., Luo, H., Xu, Z., & Wu, B. (2025). Archives of Gerontology and Geriatrics, 133. 10.1016/j.archger.2025.105806

Abstract

Abstract

Background: Previous research has shown poor oral health and neighborhood environment are both risk factors for cognitive decline among older adults. Little research has assessed the synergistic effects of poor oral health and neighborhood environment on cognitive health. This study examined whether neighborhood environment moderates the relationship between edentulism and cognitive function over time. Methods: Using data from the Health and Retirement Study, we analyzed 9,994 adults aged 60 and older with 39,976 person-wave observations over 14 years (2006–2020). Cognitive function was measured using the modified Telephone Interview for Cognitive Status. Edentulism status was self-reported complete tooth loss. Neighborhood environment included perceived neighborhood cohesion and disorder. We used linear mixed-effect models to examine the moderation effect of neighborhood environment on the association between edentulism and cognitive function over time. Results: Edentulous participants (22.4 %) showed an accelerated decline over time in cognitive function compared to dentate participants (β = -0.57, 95 % CI: -0.98, -0.16). The analysis revealed that neighborhood cohesion moderated the relationship between edentulism and cognitive function over time (β = 0.08, 95 % CI: 0.01, 0.15). Specifically, among individuals reporting higher neighborhood cohesion, the negative effect of edentulism on cognitive decline was attenuated. Neighborhood disorder had no significant associations with cognitive function. Conclusions: This study demonstrates the relationship between edentulism and cognitive function varies by levels of neighborhood cohesion. The findings highlight the significance of neighborhood context in understanding the relationship between oral health and cognitive aging and suggest interventions addressing community environment may be particularly relevant for older adults with oral health challenges.

Trajectory of Cognitive Decline Across Different Racial/Ethnic Groups: The Role of Edentulism

Liu, R., Qi, X., Luo, H., & Wu, B. (2025). Research on Aging, 47(5), 297-307. 10.1177/01640275251315850

Abstract

Abstract

This study examines whether age-related cognitive decline varies by race/ethnicity and how edentulism moderates these effects. Data from the Health and Retirement Study (2006–2020), including 23,669 respondents aged 51 and above across 189,352 person-wave observations were analyzed. Of all respondents, 13.4% were edentulous at baseline, with 65.4% identified as non-Hispanic White, 20.5% non-Hispanic Black, and 14.18% Hispanic. Results from linear mixed-effect models indicated that compared to non-Hispanic Whites, Hispanic and non-Hispanic Black participants exhibited lower baseline cognition scores but slower cognitive decline with age. For edentulous Hispanic participants, this slower rate of decline was attenuated by 0.03 units per year (95% CI: −0.06, −0.01, p =.049). The findings highlighted the need for targeted interventions and policies to improve oral health, particularly for Hispanic populations. Addressing oral health disparities could help mitigate cognitive decline in this group and reduce cognitive health disparities across racial/ethnic groups.
