We sought to 1) quantify disparities in severe maternal morbidity (SMM) and distributions of resources by race and racial composition of county, and 2) determine whether a hypothetical intervention on resources would reduce racial disparities in SMM, using linked birth certificates and claims from Medicaid beneficiaries giving birth from 2014-2019 in rural North Carolina (61 rural counties, 77,665 births). We used ratio of mediator probability weights to enact a hypothetical intervention that would equalize distributions of pregnancy care provider ratios and obstetric units across race and racial composition of county. Despite observed disparities in the distributions of resources and SMM, we were unable to demonstrate that the hypothetical interventions would reduce SMM. This may be due to a lack of common support - marginalized groups never experienced the more optimal extremes of the healthcare resources distributions that privileged groups did. Our findings may have implications for the use of causal inference methods for addressing health disparities more broadly: if distributions of resources among privileged groups are outside those that marginalized groups experience, hypothetical interventions on these distributions cannot be emulated with data.","PeriodicalId":7472,"journal":{"name":"American journal of epidemiology","volume":" ","pages":""},"PeriodicalIF":5.0,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143810292","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}

Overuse, underuse, and misuse are common, resulting in morbidity and mortality affecting billions of individuals across the world. Pharmacoepidemiology provides important insights into drug utilization, safety, and effectiveness in large populations, and it is an important method to identify opportunities to improve the value of therapeutics in clinical practice. However, for these opportunities to be realized, interventions to improve prescribing must be developed, evaluated, and implemented in the real world. We provide an overview of this process, focusing especially on how such interventions can be designed and deployed to maximize scalability, adoption, and impact. Prescribing represents a complex behavior with barriers and enablers, and interventions to improve prescribing will be most successful when developed, piloted and refined to maximize provider and patient acceptability. Carefully developed evaluations of interventions are also critical, and varied methods are available to empirically evaluate the intended and potential unintended consequences of interventions. With illustrative examples from the peer-reviewed literature, we provide readers with an overview of approaches to the essential and growing field of interventional pharmacoepidemiology.

Physical activity has demonstrable effects on body composition and overall health; however, there is little evidence for how physical activity influences AAT patterns and body composition in postmenopausal women. We emulated a target trial of physical activity interventions, including the 2018 Physical Activity Guidelines for Americans recommendations (≥150 minutes/week), on 3-year changes in AAT and body composition. We analyzed data from 4451 postmenopausal women aged 50-79 years in the Women's Health Initiative (WHI) with repeated whole body Dual X-Ray Absorptiometry (DXA) scans with derived abdominal visceral (VAT) and subcutaneous adipose tissue (SAT). The mean AAT and body composition measures were estimated with the parametric-g formula. Over 3 years, interventions of increasing minutes of moderate activity would result in dose-dependent reductions in AAT, overall body fat and increases in lean soft tissue, with the greatest estimated benefit at the 2018 physical activity guideline recommendations. Compared to no intervention, if all participants had adhered to ≥150 mins/week of moderate physical activity, they would have 16.8 cm2 lower VAT (95% CI: -23.1, -10.4), 26.8 cm2 lower SAT (95% CI: -36.3, -17.3), 1.3% lower total body fat (95% CI: -1.8, -0.7), 1.2% higher total lean soft tissue (95% CI: 0.7-1.8), and 2.6 kg lower bodyweight (95% CI, -3.6, -1.5). We saw similar patterns in vigorous-intensity activity interventions. These results suggest that postmenopausal women who adhere to physical activity guideline recommendations would experience beneficial body composition changes over 3 years.","PeriodicalId":7472,"journal":{"name":"American journal of epidemiology","volume":" ","pages":"1032-1042"},"PeriodicalIF":5.0,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141589436","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}

In April 2022, there was a worldwide outbreak of mpox (formerly called monkeypox) that resulted in an international public health emergency. The TND has been used in a few studies to investigate vaccine effectiveness and risk factors of mpox, using epidemiologic databases. However, several issues prevent such a study design from being valid for this purpose. Problems stem from stigma surrounding mpox, which affects a person's decision to seek health care. This poses a challenge to the similar health care-seeking behavior assumption that is central for test-negative studies. Further limitations include the differential diagnoses of mpox, which have notable differences from mpox that may be easily detected by clinicians or patients but are unlikely to be included in epidemiologic databases or electronic health records. Herein, the caveats regarding the use of the TND are discussed in the context of the mpox outbreak, as well as potential steps that may allow it to be used effectively.","PeriodicalId":7472,"journal":{"name":"American journal of epidemiology","volume":" ","pages":"908-912"},"PeriodicalIF":5.0,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141981483","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}
