This study explores the relationship between individual and neighborhood-level SDoH and TBI outcomes to understand the extent of their influence on long-term recovery. Hybrid panel models that decompose time-varying predictors into between- and within-person effects were used to examine the relationships between SDoH and participation in the community, life satisfaction, and global functioning for persons with moderate to severe TBI one to 30 years post-injury. Participants were 9263 persons, distributed nationally, who received inpatient rehabilitation for TBI and enrolled in the TBI Model Systems longitudinal study. Individual-level SDoH included sex, race/ethnicity, education, employment, insurance, primary means of transportation, and rurality. The Social Vulnerability Index (SVI) was used as an indicator of neighborhood disadvantage. Results indicated that neighborhood-level SDoH accounted for differences in outcomes between individuals but not due to change in a given individual's neighborhood. These findings were robust to the inclusion of numerous individual-level SDoH, which were also associated with the outcomes. Individual-level SDoH accounted for differences in outcomes both between individuals and with change in a given individual's status. Among four thematic subscales constituting the SVI, the socio-economic status subscale was consistently associated with all three outcomes.</div></div>","PeriodicalId":47780,"journal":{"name":"Ssm-Population Health","volume":"30 ","pages":"Article 101795"},"PeriodicalIF":3.6,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143890691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing on a recent review and theoretical integration, we describe six pairs of contrasting cultural defaults that were common in how the U.S. and some East Asian nations responded to the pandemic: (1) optimism-uniqueness vs. realism-similarity, (2) single vs. multiple causes, (3) expression of high vs. low arousal emotions, (4) influence-control vs. wait-adjust, (5) personal choice-self-regulation vs. social choice-social regulation, and (6) promotion vs. prevention. These historically-derived defaults are often outside of individual awareness, but are reflected in and reinforced by institutional practices and policies, the media, and everyday interactions. They are infused with cultural values, understood as the “right way” to be or behave, and are adaptive in their respective contexts. Importantly, both constellations of cultural defaults are viable depending on the problem to be solved. We then provide six specific ways in which public health officers might productively consider these and other cultural defaults when preparing for the next crisis and planning how to effectively motivate people to protect their own and others’ health. Our hope is to facilitate efforts to include a focus on culture within the scope of the social determinants of health and to encourage more partnerships between behavioral scientists and public health practitioners. Recognizing the cultural defaults of the various “publics” they seek to protect is critical as U.S. public health officers aim to promote health for all, a significant and complex challenge in the increasingly individualistic U.S.</div></div>","PeriodicalId":47780,"journal":{"name":"Ssm-Population Health","volume":"30 ","pages":"Article 101792"},"PeriodicalIF":3.6,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143941864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article presents a framework and measures to describe county-level immigration policy contexts. We developed multisectoral indicators of immigration policy contexts by linking policies and social conditions of inequity to immigration policy through mechanisms of structural racism. Using the indicators, we constructed measures of county-level immigration policy contexts in California. Two indices measured the extent of local 1) inclusive policymaking and 2) social inequity that is reinforced by immigration policy. We categorized counties into four typologies of local immigration policy contexts using the index scores. We used maps and Poisson regression analyses to examine geographic and demographic variations in the scores and typologies. We found that counties in metropolitan regions had the highest inclusive policymaking scores. Rural or agricultural counties had the highest social inequity scores. Inclusive policymaking and social inequity did not always align; some counties with many inclusive policies also had high social inequity. The counties represented in each typology of local immigration policy contexts shared unique geographic characteristics. Ultimately, our findings show that local immigration policy contexts are the product of two distinct mechanisms, and they vary across California, an inclusive state. Researchers must consider local contexts when investigating the social determinants of Latino health.
