This hampers efforts to characterize heat burden inequities and guide interventions for vulnerable populations.</p><p><strong>Objectives: </strong>We developed an approach to estimate individual and subgroup-specific health impacts from modeled IETs before and during extreme heat events for three U.S. cities: Atlanta, Georgia (hot-humid), Detroit, Michigan (temperate), and Phoenix, Arizona (hot-dry).</p><p><strong>Methods: </strong>IET profiles were estimated using modeled parcel-linked population microdata, housing-specific indoor temperatures from building energy models, ambient temperatures from urban-scale climate models, and time activity patterns from surveys. We linked each IET profile to daily OATs, then fit mixed-effects regressions to predict \"equivalent\" OATs (eOATs), based on IET, housing, and demographics. We assigned risk ratios (RRs) from existing literature on all-cause mortality, all-cause emergency department (ED) visits, and preterm births to each person-day's eOAT and estimated 5-day-extreme-heat absolute risks (ARs) by age-race-income-occupation subgroup.</p><p><strong>Results: </strong>The eOATs, RRs, and ARs differed between people due to variability in IETs and baseline health outcome incidence rates. All-cause mortality RRs ranges were 1.00-1.16 (Atlanta), 1.01-7.08 (Detroit), and 1.00-6.38 (Phoenix). All-cause-mortality ARs ranged 0.01-32 (Atlanta), 0.01-1,100 (Detroit), and 0.01-950 (Phoenix) per 100,000 persons. ED visit ARs ranges were 0.2-270 (Atlanta) and 0.04-6,200 (Phoenix) per 100,000 persons. Heat mortality ARs were higher among older adults and, only in Detroit, in young, Black, outdoor workers (median = 6.6 per 100,000) compared to young, non-Black, higher-income, indoor workers (median = 0.3 per 100,000).</p><p><strong>Discussion: </strong>When IETs can be estimated or directly measured, person-specific eOATs can be used to estimate the subgroup-specific heat-health burdens that would be experienced without adaptive behaviors. This approach could be adapted for other contexts to inform climate preparedness and justice policies. https://doi.org/10.1289/EHP15223.</p>","PeriodicalId":11862,"journal":{"name":"Environmental Health Perspectives","volume":" ","pages":""},"PeriodicalIF":10.1,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144265743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Odds ratios and 95% confidence intervals were estimated using a conditional logistic model in a two-stage approach, further adjusting for smoking, occupation, marital status, BMI, and serum cholesterol level in primary models.</p><p><strong>Results: </strong>In the main model hexachlorobenzene (HCB) showed a positive association with ALS occurrence. In contrast, Σnon-dioxin-like (NDL) PCB and ΣDDT were significantly inversely associated with ALS incidence. Most other POP groups were non-significantly inversely associated with ALS risk. In co-pollutant models, the only notable changes were that Σdioxin-like PCB and ΣHCH showed large non-significant, elevated, ORs, suggesting some negative co-pollutant confounding. There were some suggestions of stronger findings when limiting to some subgroups.</p><p><strong>Discussion: </strong>We found little evidence that POPs were associated with ALS, but we identified a suggestive positive association with HCB and HCH. ΣNDL PCB and ΣDDT were inversely associated with ALS. This could suggest protective mechanisms or uncontrolled confounding by neuroprotective factors (e.g. fish oils). https://doi.org/10.1289/EHP16539.</p>","PeriodicalId":11862,"journal":{"name":"Environmental Health Perspectives","volume":" ","pages":""},"PeriodicalIF":10.1,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144247065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
