Public health research suggests that children exposed to localized air pollution may suffer from cognitive impairment during testing or chronic conditions such as asthma that could influence their academic performance. After controlling for the appropriate confounding variables, our findings indicate that a 1-unit increase (or an equivalent one-third increase in the standard deviation) in the average amount of particulate matter observed over the past 6 years in a school district reduces the average standardized test score by about 4%. In addition, a typical student in a California school district in the two highest quintiles of PM 2.5 exposure (controlling for other causal factors) exhibits standardized test scores closer to the fifth-grade equivalency level than the sixth. These results support the benefits of indoor air pollution mitigation as a likely cost-effective intervention to improve student academic success in primary school.</p>","PeriodicalId":11827,"journal":{"name":"Environmental Health Insights","volume":"18 ","pages":"11786302241293292"},"PeriodicalIF":2.3,"publicationDate":"2024-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11531670/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142567591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this gap in knowledge, we conducted a scoping review to determine the extent to which disparities in environmental exposures between SGM and non-SGM (ie, heterosexual and cisgender) populations have been measured in the United States. We searched PubMed for studies that were (1) peer-reviewed; (2) written in English; (3) quantitatively measured environmental exposures; (4) included 1 or more groups identifying as a sexual minority, gender minority, or both; (5) compared to the general population; (6) in the United States; and (7) published on or after January 1, 2011. Our scoping review identified very few studies that examined and documented environmental exposure disparities between SGM and non-SGM populations in the United States. These studies focused mostly on cigarette smoke exposures. None examined environmental exposure disparities between gender minority and cisgender populations. To address this critical gap in environmental health research for SGM populations in the short term, researchers can merge existing environmental data (eg, data from the Environmental Protection Agency) with SGM population data. Longer-term solutions require systematically including validated sexual orientation and gender identity measures across federal, state, and local datasets, as well as increased funding for original research that explores diverse environmental exposures. Taken together, these efforts can significantly advance our ability to identify and address environmental health inequities experienced by SGM people.</p>","PeriodicalId":11827,"journal":{"name":"Environmental Health Insights","volume":"18 ","pages":"11786302241296225"},"PeriodicalIF":2.3,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11528665/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142567413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
