Housing insecurity is increasing among older adults in the U.S., yet the impact of housing-related distress on health and well-being in this population is understudied. This study uses three waves of prospective data from a national sample of U.S. adults aged 50+ years (Health and Retirement Study, N = 12,998) to examine associations between housing distress and 35 indicators of physical, behavioral, and psychosocial health and well-being four years later. We also assess differences by military veteran status in stratified analyses. After adjustment for a rich set of potential confounders, we found that housing distress was associated with most (7/12) indicators of psychological well-being and distress (e.g., lower life satisfaction, purpose; higher depressive symptoms, hopelessness), some (3/14) indicators of physical health (e.g., more chronic conditions, lower self-rated health), and higher loneliness, but was not associated with health behaviors after correction for multiple testing. Results stratified by veteran status indicated stronger associations among non-veterans. These findings highlight the need for targeted interventions to reduce housing insecurity among older adults and mitigate its psychological and physical health consequences.

The extent to which a house is structurally sound is an important marker of housing quality and a determinant of human health. In India, the share of homes that are structurally sound has increased considerably over the past few decades, yet geographical variations persist especially between urban and rural communities. Using data from two rounds of India's National Family Health Survey in 2016 and 2021, we estimated a multilevel model using a Markov Chain Monte Carlo procedure to examine changes in the share of finished, semi-finished, and rudimentary housing in urban and rural communities across India's 720 districts. In urban communities, the share of finished housing increased slightly from 82.9 % (95 % CI: 82.7–83.1) in 2016 to 83.2 % (95 % CI: 83.0–83.4) in 2021. In rural communities, the share of finished housing increased from 41.3 % (95 % CI: 41.1–41.4) in 2016 to 48.5 % (95 % CI: 48.3–48.6) in 2021. However, we found substantial between-district disparities, and that the between-community variation increased in many of the districts that experienced overall improvements in housing quality for all three measures of housing quality between 2016 and 2021. District administrations in India can use these results to understand the quality of housing in their jurisdictions. These results can help district administrators work with national policy makers to refine policies aimed at improving housing quality.

Objectives
This study aims to investigate the time-dependent pattern of employees’ work stress responses. It seeks to determine whether there is a day-of-the-week effect in employees’ physiological reactions to workplace stressors on an intra-week scale.
Methods
Utilizing seven-year (2017–2023) biometric data from financial sector employees in Eastern China, we analyzed the association between daily stock returns and cardiovascular biomarkers. A counterfactual analysis during holiday periods was conducted to isolate work-cycle-specific effects from general biological rhythms.
Results
Declines in company stock prices significantly elevated employees’ systolic blood pressure and blood lipids from Tuesdays to Thursdays (TTTday), with the effect peaking on Tuesdays, remaining significant on Wednesdays, and failing to reach statistical significance on Thursdays. No significant effects were observed on Mondays or Fridays. Holiday-period analyses confirmed this TTTday vulnerability window as a work-cycle-specific phenomenon.
Conclusions
Employees exhibit rhythmic variations in effort and recovery on the sub-weekly scale, and this leads to varying degrees of physiological responses to workplace stress during the workweek.

Background
Solastalgia is a factor in understanding the suffering of children and young people of Indigenous communities in Colombia, which, in addition to extractivism, face multiple crises as forced displacement, the recruitment of children and adolescents for war, food insecurity, and the weakening of cultural practices.
Objective
To examine the association between psychosocial factors, as resilience, hopelessness, substance use, family problems, adverse childhood experiences and food insecurity, and solastalgia among two Colombian Indigenous Communities living in polycrisis contexts. It was hypothesized that hopelessness and food insecurity would be positively associated with solastalgia, while resilience would be negatively associated.
Participants and setting
Participants (N = 142) comprised all children and young people between the ages of seven and 21 from two Indigenous communities (Embera Dobidá People). Both communities have experienced multiple crises, such as extractivism, migration, and armed conflict, and present high rates of suicidal behavior, food insecurity, and other health problems.
Methods
A cross-sectional design was implemented, integrating the study within a broader public mental health intervention program. Participants completed validated instruments, including the Connor-Davidson Resilience Scale, the Brief Solastalgia Scale, CRAFFT (Car, Relax, Alone, Forget, Family/Friends, Trouble), PACES (Parenting, Behavior, Emotions and Suicidal Risk) and Food Security Scale. Multiple regression analyses were performed.
Results
Solastalgia was significantly associated with hopelessness, resilience and food insecurity. The regression model explained 55.8 % of the variance in solastalgia scores. Hopelessness emerged as the strongest predictor (beta = .521, p < .001), followed by resilience, family problems, substance use and food insecurity.
Conclusions
Among the factors related to solastalgia, proposed explanatory factors include hopelessness, problematic substance use, family problems, adverse childhood events, and structural factors such as displacement and food insecurity. The 99.3 % of participants without a formal reported diagnosis of mental health conditions highlights the limited access to mental health services in these rural areas.
背景：solastalgia是理解哥伦比亚土著社区儿童和年轻人痛苦的一个因素，除了采掘之外，他们还面临着被迫流离失所、儿童和青少年被征召参加战争、粮食不安全以及文化习俗的削弱等多重危机。目的研究生活在多重危机环境中的两个哥伦比亚土著社区的心理社会因素，如恢复力、绝望、药物使用、家庭问题、不良童年经历和粮食不安全，与太阳痛之间的关系。据推测，绝望和食物不安全与solastalgia呈正相关，而弹性则呈负相关。参与者和环境参与者（N = 142）包括来自两个土著社区（Embera dobida people）的7至21岁的所有儿童和年轻人。这两个社区都经历了多重危机，如采掘、移民和武装冲突，并呈现出高自杀率、粮食不安全和其他健康问题。方法采用横断面设计，将本研究纳入更广泛的公共心理健康干预计划。参与者完成了经过验证的工具，包括康纳-戴维森弹性量表，简短的Solastalgia量表，craft（汽车，放松，独自，忘记，家庭/朋友，麻烦），PACES（养育，行为，情绪和自杀风险）和食品安全量表。进行多元回归分析。结果太阳痛与绝望、恢复力和粮食不安全显著相关。回归模型解释了55.8%的太阳痛评分差异。绝望是最有力的预测因素（beta = .521, p < .001），其次是适应力、家庭问题、药物使用和食品不安全。结论在与太阳痛相关的因素中，可能的解释因素包括绝望、问题药物使用、家庭问题、童年不良事件以及流离失所和粮食不安全等结构性因素。99.3%的参与者没有正式报告的精神健康状况诊断，这突显了这些农村地区获得精神卫生服务的机会有限。

As standardized geospatial units with social meaning and direct political governance, school districts may be an optimal functional definition of residential neighborhoods. However, few measures of population health are available at the school district level. In this descriptive study, we implemented a novel application of an established geographic crosswalk framework to estimate population-weighted age-specific life expectancies for all 13,592 school districts in the United States for the years 2010–2015. Our results revealed significant variation in life expectancies across school districts and across the life span – including a gap in life expectancy at birth of almost thirty years. We further identified meaningful differences in the extent of inequalities in life expectancy within states, as measured by standard deviation in school district age-specific life expectancies. These findings highlight the utility of using a crosswalk approach to estimate population health and health disparities at the school district level.

Background
The built environment is a key intervenable target for public health, yet its nonlinear and threshold relationships with schizophrenia incidence remain poorly understood.
Methods
We analyzed township-level schizophrenia incidence (2019–2023) in Anhui, China, using data from the National Severe Mental Disorder Registration System. Built environment features were derived from multi-source geographic data. We characterized spatiotemporal patterns and modeled associations using Ordinary Least Squares (OLS), Geographically Weighted Regression (GWR), and an interpretable XGBoost model explained by SHAP values.
Results
The mean annual incidence was 13.46 per 100,000, with significant spatial clustering (Moran's I = 0.47, P < 0.001). The SHAP-XGBoost model outperformed both OLS and GWR. Key built environment predictors included population density, NDVI, distance to blue space, street connectivity, and blue space area. These factors exhibited complex nonlinear relationships with schizophrenia risk; for example, population density showed a U-shaped association with a risk threshold around 15,000 persons/km2. Interaction effects between multiple features were also identified.
Conclusion
This study provides robust evidence that the built environment is significantly and nonlinearly linked to schizophrenia incidence. The identified thresholds and interactions offer concrete, actionable guidance for urban planning aimed at mental health promotion.
建筑环境是公共卫生的关键可干预目标，但其与精神分裂症发病率的非线性和阈值关系仍然知之甚少。方法利用国家严重精神障碍登记系统的数据，分析安徽省2019-2023年乡镇精神分裂症发病率。建筑环境特征是由多源地理数据导出的。我们使用普通最小二乘法（OLS）、地理加权回归（GWR）和SHAP值解释的可解释的XGBoost模型来表征时空模式和建模关联。结果年平均发病率为13.46 / 10万，具有显著的空间聚类性（Moran’s I = 0.47, P < 0.001）。SHAP-XGBoost模型优于OLS和GWR。关键的建筑环境预测指标包括人口密度、NDVI、到蓝色空间的距离、街道连通性和蓝色空间面积。这些因素与精神分裂症风险表现出复杂的非线性关系；例如，人口密度与1.5万人/平方公里左右的风险阈值呈u型关系。还确定了多个特征之间的交互效应。结论本研究提供了强有力的证据，表明建筑环境与精神分裂症发病率存在显著的非线性联系。确定的阈值和相互作用为旨在促进心理健康的城市规划提供了具体的、可操作的指导。

While recreational dancing has been associated with positive health outcomes, professional dancers tend to experience more mental health problems. Here, we studied the relationship between self-reported engagement and achievement in dance (from no involvement to high-level professional dancing) and mental health problems including work-related depressive symptoms, emotional exhaustion, and registry-based psychiatric diagnoses (major depression, anxiety, and stress-related diseases). Utilizing a genetically informative population sample of 6610 Swedish twins, we estimated heritability for dance achievement and associations between dance achievement and mental health outcomes, and tested whether observed associations are consistent with causal effects by accounting for familial confounding using a co-twin control design. Individual differences in dance achievement were more heritable in females (60%) than in males (29%). Professional dancers had a higher risk for mental health problems than recreational dancers and non-dancers, but these associations became non-significant after adjusting for familial confounding, suggesting that shared familial factors – rather than professional dancing itself – largely explained the elevated risk. In contrast, we found no evidence for a protective effect of recreational dancing on mental health. These findings highlight the importance of considering underlying familial and genetic factors when addressing mental health risks in professional dancers, and they point toward future interventions focusing on early identification and support for vulnerable individuals rather than targeting dance practice itself as a causal factor.

Against the backdrop of simultaneous national agendas for green transition and healthy ageing, the nutritional behaviour of older adults is being reshaped by emerging forms of institutional governance. Drawing on four waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS, 2008, 2011, 2014, and 2018), which are linked to the full texts of provincial government work reports from 22 provinces, this study constructs an index of "governmental green development attention" to rigorously assess whether provincial-level prioritization of green development is associated with dietary diversity among older adults. Baseline estimates from two-way fixed-effects models show that, after controlling for both individual- and provincial-level covariates, higher governmental attention to green development is significantly associated with greater dietary diversity in later life. We further identify three channels through which this association appears to operate: (i) heightened agenda salience and social participation; (ii) the framing of "green" as "healthy" and the diffusion of corresponding consumption norms; and (iii) improvements in public environmental conditions and basic service provision. A battery of robustness checks—including multilevel and random-effects specifications, the inclusion of province–year interactions, adjustments to the operationalization of the core explanatory variable, and double machine learning (DML) estimates of causal effects—consistently supports the main findings. Additional analyses show that the supply-side dimension of green transition exerts the strongest influence; that the volume of granted green patents is likewise positively associated with dietary diversity; and that the relationship between policy attention and dietary balance exhibits an inverted U-shape. Heterogeneity analyses indicate that the association is markedly stronger among men, older adults who do not live alone, and residents of provinces with a higher share of secondary industry in GDP, suggesting that certain subgroups are more responsive to institutional environmental signals. Taken together, this study, grounded in the logic of limited attention, traces a "policy signal — cognitive/behavioural response" transmission pathway, offering new evidence on the behavioural health spillovers of environmental governance and informing nutrition-oriented interventions for ageing societies.

Drawing on four waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS, 2008, 2011, 2014, and 2018), which are linked to the full texts of provincial government work reports from 22 provinces, this study constructs an index of \"governmental green development attention\" to rigorously assess whether provincial-level prioritization of green development is associated with dietary diversity among older adults. Baseline estimates from two-way fixed-effects models show that, after controlling for both individual- and provincial-level covariates, higher governmental attention to green development is significantly associated with greater dietary diversity in later life. We further identify three channels through which this association appears to operate: (i) heightened agenda salience and social participation; (ii) the framing of \"green\" as \"healthy\" and the diffusion of corresponding consumption norms; and (iii) improvements in public environmental conditions and basic service provision. A battery of robustness checks—including multilevel and random-effects specifications, the inclusion of province–year interactions, adjustments to the operationalization of the core explanatory variable, and double machine learning (DML) estimates of causal effects—consistently supports the main findings.

Background
Chinese unique sociocultural context surrounding tobacco reinforces smoking behaviors, potentially through its influence on smokers’ expectancies of smoking-related outcomes. Network analysis effectively explores the intricate relationship between social tobacco cultural attitudes and smoking outcome expectancies among Chinese smokers.
Methods
The study included 1382 current smokers. A mixed graphical model was employed to construct internal and combined networks of social tobacco cultural attitudes and smoking outcome expectancies. Additionally, node strength centrality, edge weights, and stability were analyzed.
Results
In the network of social tobacco cultural attitudes, sharing cigarettes (jingyan or sanyan) was identified as the central node (Str = 0.855). For smoking outcome expectancies, stimulus/state enhancement exhibits the highest strength centrality (Str = 0.860). In the total integrated network of smoking outcome expectancies and social tobacco cultural attitudes, social facilitation outcome expectancies demonstrated the highest strength centrality between the two variables (Str = 0.894).
Conclusions
In this study, social facilitation outcome expectancies were central in the combined network of social tobacco cultural attitudes and smoking outcome expectancies, showing a direct and positive link to multiple tobacco cultural attitudes. This finding illustrates how sociocultural factors are interconnected with individual expectancies of smoking outcomes, identifying the central positioning of social facilitation expectancies variables within the sociocultural attitudes–outcome expectancies network. These insights provide new perspectives for developing culturally adaptive tobacco control interventions, such as reshaping tobacco cultural symbols to promote “smoke-free weddings” and “refusing cigarette gifts.”
