Dr. Ang, with colleagues, has published “Fluid emotions, managed disruption: Understanding involuntary state-led resettlement in Singapore” in Cities. This study examines involuntary state-led resettlement in Singapore among low-income public rental residents, using interviews from two estates. It finds emotions are shaped by prior state interactions, neighbourhood ties, and housing histories; that actions reflect attempts to regain control or disengage; and that impacts must be assessed from the start, not only after relocation, to inform policy design.

Dr. Garcia is part of a team that has published “Heterogeneity in healthy aging among U.S. Latinos: a dual functionality perspective,” on The Journals of Gerontology, Series B: Psychological Sciences and Social Sciences. Using 16 years of American Community Survey data, this study examined healthy aging among U.S. Latinos using “dual functionality,” defined as freedom from both cognitive and physical limitations. Functional health declined with age, but disparities varied by heritage, nativity, and sex. South Americans showed the strongest outcomes, while island-born Puerto Ricans consistently experienced the poorest. Foreign-born Latinos generally had better functional health than U.S.-born peers, though this advantage weakened with age, especially among women. Findings highlight persistent structural inequalities shaping aging outcomes.

Dr. Garcia is part of a team that has published “Heterogeneous Impairment Patterns among Midlife Latinos in the United States” on The Journals of Gerontology, Series B: Psychological Sciences and Social Sciences. Using American Community Survey data (2008–2019), this study examines impairment among U.S. Latinos aged 45–64, emphasizing subgroup differences. Results reveal major heterogeneity: Puerto Rican, Black, multiracial, American Indian, and Alaska Native Latinos face especially high impairment risks. U.S.-born Latinos, childhood migrants, and long-term residents also show elevated probabilities. The findings demonstrate that treating Latinos as a single pan-ethnic group obscures important disparities, limiting effective health policy and intervention efforts.

Dr. Lee is part of a team that has published “Dissipative quantum dynamics in static networks with different topologies” on New Journal of Physics. This study examines how network topology influences dissipative quantum dynamics in spin networks coupled to thermal bosonic reservoirs. Using a Lindblad master equation framework, the authors first analyze small Ising-spin networks to show how different structures affect quantum population and coherence decay. They then develop a mean-field approach for large-scale networks, linking complex topologies to coherence behavior. Findings demonstrate that quantum coherence is highly sensitive to network structure, with implications for entangled-state dynamics, complex systems, social models, epidemiology, and biological processes.

Dr. Lee is part of a team that has published “Transitional Justice and Health, Happiness, and Solidarity: An Analysis of the 2020 National Survey in Taiwan” on International Journal of Social Determinants of Health and Health Services. Using Taiwan as a case study, this research examines how attitudes toward transitional justice relate to well-being and self-defense solidarity in a post-authoritarian society facing geopolitical threats. Based on a 2020 national survey, the study finds that support for recognizing past state violence and promoting reconciliation is positively associated with physical health, happiness, and willingness to defend society against external political violence.

Dr. Visaria and Dr. Malhotra are part of a team that has published “Association of depressive symptomatology with healthcare utilization among community-dwelling older adults: an electronic medical records-based longitudinal study in Singapore” in Aging & mental health. This study of community-dwelling older adults in Singapore found that depressive symptoms were strongly associated with greater healthcare utilization. Using longitudinal survey and electronic medical record data from 4,049 participants, researchers showed that higher depressive symptom scores increased the likelihood of emergency department visits, frequent ED use, and hospitalizations within 12 months. Each unit increase in depressive symptoms raised odds of ED visits by 5% and hospitalizations by 6%. Findings emphasize the importance of early depression identification and treatment to reduce healthcare burden among older adults.

Dr. Zajacova is part of the team that has published “Country-level gender inequality and sex disparities in adolescent chronic pain: A 47-country analysis” on Preventive Medicine. This study examined how national gender inequality influences adolescent chronic pain and sex disparities across 47 countries. Using data from over 244,000 adolescents, researchers found that higher gender inequality was linked to greater overall pain prevalence but smaller female–male disparities because boys’ pain increased more sharply in unequal societies. Higher intimate partner violence prevalence was associated with larger female–male differences. Findings highlight the importance of structural gender inequality in shaping adolescent chronic pain patterns globally.

Dr. Zajacova is part of the team that has published “Educational Disparities in Disability in Mid- to Late-Life: How Much is Attributable to Pain?” on Journal of Aging and Health. Using 2002–2018 National Health Interview Survey data, this study investigates how chronic pain contributes to educational disparities in disability. Site-specific pain explained 18–34% of disability gaps between adults with low and high educational attainment, mainly because pain was more prevalent among less educated individuals. Effects were stronger in midlife than older age, with minimal gender differences. Findings highlight chronic pain as an important but understudied pathway linking education to disability inequality later in life.

Dr. Chiao, with colleagues, has published, “Applying the general strain theoretical framework to exploring the associations between adverse childhood experiences and problematic Internet use,” in Children and Youth Services Review. Using data from a 17-year Taiwan Youth Project, this study examined how adverse childhood experiences (ACEs) influence problematic Internet use (PIU) in young adulthood. Guided by General Strain Theory, results showed ACEs directly increased PIU risk and indirectly did so through heightened loneliness. Findings highlight the importance of emotional pathways and educational context in understanding how early adversity contributes to later problematic Internet behaviors.

Dr. Solé-Auró, with colleagues, has published “Multimorbidity trends in Catalonia, 2010–21: a population-based cohort study” in International Journal of Epidemiology. As the article title suggests, this study examines the interconnections between people with multimorbidity and their socioeconomic gradients. After stratifying a random population sample by income groups and birth cohorts, logistic regression models are used to estimate the association between multimorbidity and mortality. Results show an increasing prevalence of multimorbidity across all age groups, where lower-income individuals are the most vulnerable to related health incidence.
Dr. Kim is part of a team that has published, “Perceived age discrimination and cognitive function in older Korean adults: a cross-sectional study,” in Aging & Mental Health. This study examined the relationship between perceived age discrimination and cognitive function among older Koreans using a large national sample. Findings showed that 40.5% experienced age discrimination, which was significantly associated with poorer cognitive performance and higher odds of cognitive impairment. Even after adjusting for other factors, discrimination remained a significant predictor. The results highlight ageism as a modifiable psychosocial risk factor and emphasize the need for policies and interventions to protect cognitive health in aging populations.

Dr. Montez is part of a team that has published, “US State Policy Contexts and Mental Health Among Working-Age Adults,” in The Milbank Quarterly. This study, led by Dr. Iliya Gutin, reveals that conservative state policy contexts are significant predictors of poorer mental health among working-age adults. Findings show that shifts toward conservatism correlate with increased mental distress and a higher probability of extreme distress, regardless of pandemic-specific policies. These negative impacts are most pronounced for individuals without a college degree, suggesting that state-level policy environments worsen educational health disparities.

Dr. Lee is part of a team that has published “Spousal Loss, Depressive Symptoms, and Religious Involvement: Immediate Impact and Trajectories in Late Life” in Research on Aging. Analyzing Health and Retirement Study data from 2006 to 2018, researchers found that religious involvement significantly buffers the immediate depressive symptoms following late-life spousal loss. While faith-based engagement provides a crucial initial emotional cushion, it does not impact long-term recovery trajectories or changes in mental health over time. Consequently, while religion mitigates the acute shock of bereavement, alternative coping resources are necessary to support sustained psychological well-being.

Dr. Kim and Dr. Teerawichitchainan are part of a team that published “Childlessness and health in middle age and older adulthood: Evidence from Singapore” in European Economic Review. This study investigates the causal impact of childlessness on the health of 1,500 Singaporeans aged 50 and older. By utilizing infertility and childless siblings as instrumental variables, the researchers address potential biases in previous data. Findings reveal that childlessness significantly increases the likelihood of poor self-reported health and mental distress. Furthermore, the analysis indicates that standard OLS models underestimate these negative effects.

Dr. Visaria and Dr. Malhotra, together with colleagues, contributed to a publication “Link between tooth loss and health expectancy: findings from a prospective Singaporean population-based cohort study of older adults” in Journal of Epidemiology & Community Health. This study examined how the number of teeth affects health expectancy—years lived without limitations in activities of daily living (ADLs) or physical function—among adults aged 60 years and older in Singapore. Older adults with more natural teeth generally experienced longer periods of independent living. Differences were greater among men and those with lower education. Results also suggested that removable dental prostheses may support healthier aging, highlighting the importance of both tooth retention and prosthetic rehabilitation.

Dr. Tareque and Dr. Chiu, together with colleagues, have published “Sixteen-year longitudinal associations between loneliness and depressive symptoms among older adults” in Aging & Mental Health. This study examines the long-term relationship between loneliness and depressive symptoms among U.S. adults aged 60+ over a 16-year period using Health and Retirement Study data from 2006 to 2022. Two analyses tested whether loneliness predicts later depression and whether depression predicts later loneliness. Results showed lonely participants had nearly double the odds of future depressive symptoms. Baseline depression also increased later loneliness risk. Cognitive impairment predicted loneliness, while women and those with poorer self-rated health were more likely to develop.

Dr. Teerawichitchainan and Dr. Kim are part of the team that has recently published “Childlessness and Advance Care Planning in Midlife and Late Adulthood: A Mixed-Methods Study in Singapore” in Social Science & Medicine. As the title suggests, this study examines multiple dimensions of advance care planning (ACP) by quantitative analyses and interviews with targeted respondents–childless adults aged 50+ in Singapore. While results indicate a different ACP level between childless men and women, it is further suggested that various barriers, including difficulty appointing proxies, misconceptions about costs, and competing caregiving demands, together contribute to the overall modest ACP level in Singapore.

This study examines how race, ethnicity, and sex shape marital status and living arrangements after age 50. An innovative Bayesian multistate life table approach is employed to reveal different matrimonial patterns of white, black and Hispanic adults, and to investigate how sex–such as the case for female minorities–closely interrelates to an individual’s social and economic security in later life.
Dr. Malhotra is part of team that has published “Advance Care Planning and long-term bereavement in caregivers of patients with metastatic cancer” in Journal of Pain and Symptom Management. This study examines associations between ACP engagement and caregivers’ risk of complicated grief and anxiety six months after a patient's death, moderation by patient age and patient-caregiver relationship, and mediation by patient’s emotional distress and caregiver preparedness for patient’s death. The Brief Grief Questionnaire is used to assess caregivers’ risk of complicated grief, and anxiety with the anxiety subscale of the Hospital Anxiety and Depression Scale. A higher ACP engagement, as the study’s result points out, may benefit diverse groups of bereaved caregivers of patients with cancer.

Dr. Lusk is part of team that has published “Calcitonin Gene–Related Peptide Inhibitors and Cardiovascular Events in Patients With Migraine” in Neurology. This retrospective cohort study used insurance claims data to evaluate whether initiating calcitonin gene–related peptide (CGRP) inhibitors for migraine is associated with cardiovascular risk. Among individual outcomes, only ischemic stroke showed a significant increase, while myocardial infarction, revascularization, retinal artery occlusion, and intracranial hemorrhage were not significantly associated. Overall, initiation of CGRP inhibitors was linked to a modest increase in cardiovascular risk in patients with migraine.

Dr. Minagawa and Dr. Luy, together with colleagues, have published “Why do women live longer than men, but spend more time in poor health? A decomposition analysis of the gender gap in unhealthy life years across Europe” in European Journal of Epidemiology. This study tested the “longevity hypothesis,” which suggests that women spend more years in poor health mainly because they live longer. The study examined gender differences in unhealthy life years at age 50 across several health indicators. Women consistently experienced more years in poor health than men. Results varied somewhat across health indicators and countries, but overall findings support the longevity hypothesis and highlight the importance of considering different dimensions of health when examining gender inequalities.

Dr. Garcia is part of team that published “Cognitive difficulties among middle-aged and older Latino adults: within-group variation across U.S. states” in The Journals of Gerontology, Series B: Psychological Sciences and Social Sciences. This study examined state-level variation in cognitive difficulties among Latinos aged 45 and older in the United States using American Community Survey data (2008–2019). Results showed substantial differences across states and Latino subgroups. U.S.-born Latinos reported higher levels of cognitive difficulties than foreign-born individuals. Higher prevalence was observed among certain heritage groups, including Puerto Ricans, Dominicans, and Cubans. The findings suggest that nativity, heritage, and state-level context interact to shape cognitive risk patterns.

Dr. Zajacova has published "Where does it hurt? A 4-S model of pain onset and recovery across body sites among older adults" in The Journals of Gerontology, Series B: Psychological Sciences and Social Sciences. This study examines the bodily distribution of pain and its covariates and proposes a framework to systematize how pain sites remain stable, spread, switch, or subside over time. The 4-S model, proposed as a framework in this study, provides valuable insights into understanding the complex interplay of pain onset and recovery and offers ways to integrate this framework into ongoing investigations of late-life pain.
