Adherence to this diet has been measured using several indices, including World Index for Sustainability and Health (WISH) and Planetary Health Diet Index (PHDI).OBJECTIVESWe aimed to investigate the associations between adherence to the EAT-Lancet reference diet, as evaluated by WISH and PHDI, with risk of new-onset cardiometabolic diseases (CMDs), risk of all-cause mortality and greenhouse gas (GHG) emissions.METHODSWe included adults (N=14,652 for CMDs and 15,318 for all-cause mortality) from the China Health and Nutrition Survey (1997-2015) in the analysis. Dietary intake data were collected and WISH and PHDI scores were computed with established methods. CMDs included myocardial infarction (MI), type 2 diabetes mellitus (T2DM) and stroke. We used Cox proportional hazard regression models, to analyze data with a mean of 10-years of follow-up from the date of baseline to the end of study or until the occurrence of the event of interest whichever came first. We adjusted for sociodemographic, anthropometric, lifestyle and dietary characteristics of participants as confounders.RESULTSGreater adherence to the EAT-Lancet reference diet, as reflected by higher WISH or PHDI scores, were inversely associated with risk of MI (Q4 vs Q1:HR=0.68 (95% confidence interval (CI): 0.48-0.96) for WISH and 0.14 (95% CI: 0.07-0.29) for PHDI), T2DM (Q4 vs Q1:HR=0.81 (95% CI: 0.67-0.96) for WISH and 0.68 (95% CI: 0.57-0.82) for PHDI), all-cause mortality (Q4 vs Q1:HR=0.80 (95% CI: 0.68-0.95) for WISH and 0.60 (95% CI: 0.46-0.80) for PHDI) in fully adjusted models (all P-trend <0.05). Both WISH and PHDI were inversely associated with GHG emissions in fully adjusted models (all P-trend <0.05). WISH and PHDI were not significantly associated with risk of stroke.CONCLUSIONSOur findings supported the co-benefits of the EAT-Lancet reference diet for both cardiometabolic health and environmental sustainability. Long-term adherence to this reference diet as effectively indicated by either higher WISH or PHDI scores may reduce the risk and burden of CMDs and all-cause mortality in Chinese adults. https://doi.org/10.1289/EHP15006.","PeriodicalId":11862,"journal":{"name":"Environmental Health Perspectives","volume":"2 1","pages":""},"PeriodicalIF":10.4,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143897409","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}

{"title":"Cumulative Human Health Risk Assessment of Regional Ozone and Volatile Organic Compounds from Unconventional Oil and Gas Sites in Colorado's Front Range.","authors":"Meagan L Weisner,Paige M Varner,I Ting Ku,Jeffrey L Collett,Brent Buck,Lisa M McKenzie","doi":"10.1289/ehp16272","DOIUrl":"https://doi.org/10.1289/ehp16272","url":null,"abstract":"BACKGROUNDMost unconventional oil and gas (UOG) extraction in Colorado occurs within the Denver Metro/North Front Range (DMNFR) ozone Non-attainment Area (NAA). Previous UOG human health risk assessments do not consider cumulative risk from both volatile organic compounds (VOCs) and criteria air pollutants (CAPs) like ozone.METHODSWe conducted a cumulative human health risk assessment (CHHRA) utilizing regulatory-grade 1- and 8-hour ozone measurements from a DMNFR United States Environmental Protection Agency (EPA) monitoring station and weekly and short-term (15 second - 1 minute) VOC air quality monitoring (AQM) data collected between 2018-2023 from ten near-pad air monitoring sites, three community sites, and one background site. Acute and chronic non-cancer hazard indices (HIs) for multiple health endpoints, as well as cancer risks, were calculated during well drilling, well completions, and production activity periods and compared between sites. VOC concentrations were compared between operations that used a petroleum-based drilling fluid versus a synthetic drill fluid. Differences in weekly chemical concentrations between sites, UOG phases, and drill muds were analyzed using repeated measures analysis of variance (ANOVA) with post-hoc pairwise comparisons with Bonferroni adjustment.RESULTSAcute HIs of VOCs and ozone ranged from 1.34 x 10-4 to 31.33 at the 95th percentile concentrations at all sites. One of the three community monitoring sites, Anthem, exceeded EPA thresholds for respiratory, immunological, and developmental endpoints during production and for the immunological endpoint during well completions. At the near-pad sites, acute hazards exceeded EPA thresholds during well completions for immunological, respiratory, reproductive, developmental, and neurological endpoints. Neurological and immunological HIs were above thresholds for the drilling phase at near-pad sites. Chronic HIs ranged from 8.43 x 10-4 to 0.47 at 95th percentile concentrations and, therefore, were below the HI threshold for all near-pad and community sites for all health endpoints. Cancer risks ranging from 209 to 335 in a million at 95th percentile concentrations were above EPA's thresholds for all sites, including the background site which is more heavily influenced by Denver-metro traffic emissions.CONCLUSIONSOur results suggest that for communities located near UOG well pads in the DMNFR ozone NAA, acute health risks persist after the implementation of best management practices to reduce emissions. Greater protection to public health could be afforded by establishing policies that require drilling and well completions to be conducted outside of summer ozone season. Further research is needed to address potential health risks from the use of synthetic drilling fluid. https://doi.org/10.1289/EHP16272.","PeriodicalId":11862,"journal":{"name":"Environmental Health Perspectives","volume":"56 1","pages":""},"PeriodicalIF":10.4,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143897408","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}
