The SDI-US (range: 4-20 points), with higher scores indicating more sustainable diets, was calculated using 24-hour dietary recall data and responses to consumer and dietary behavior questionnaires. Mean total SDI-US scores, sub-indices, and 12 individual indicators were estimated for each survey cycle. Trends were assessed using orthogonal polynomial contrasts in regression models.</p><p><strong>Results: </strong>From 2007 to 2018, total SDI-US scores showed no significant overall trend (overall mean = 13.1). Nutritional and sociocultural indicators remained relatively stable, whereas the economic indicator (food expenditures) worsened from 21.4% to 26.4% (p<0.05, linear trend) between 2007-2008 and 2017-2018. Environmental impacts initially worsened between 2007-2008 and 2013-2014 but improved through 2017-2018 (all p<0.05, quadratic trend). When stratified by age (p for interaction <0.0001), a slight decline in SDI-US was observed among adults aged ≥60 years (14.1 to 13.9, p<0.0001).</p><p><strong>Conclusion: </strong>From 2007 to 2018, total SDI-US scores largely remained unchanged, although declines occurred among adults ≥60 years and scores remained lower among adults aged 20-39 years. Ongoing monitoring and coordinated improvements across all dimensions are needed to advance sustainable diets in all age groups.</p>","PeriodicalId":48543,"journal":{"name":"Epidemiology and Health","volume":" ","pages":"e2025045"},"PeriodicalIF":2.2,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144974557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
