Prior research hypothesized that the stagnation is related to increasing austerity measures and widening socio-economic inequalities. We formally assessed the contribution of education-specific mortality trends and increasing educational inequalities to the stagnation. We used individually-linked mortality data by sex, educational attainment (low, middle, high), and age (30+) from the ONS Longitudinal Study. We compared, by sex, the observed with the expected (= projected) increase in remaining life expectancy at age 30 (e30) in 2011-2017 for the national and education-specific populations. We assessed the education-specific mortality contributions using stepwise decomposition, and the contribution of increasing educational inequalities using a scenario analysis that assumes constant inequalities. In E&W in 2011-2017, e30 increased by 1.32 years (males) and 1.14 years (females) less than expected, which translates into 2.3 and 1.9 months annually. Stagnation of the increase in e30 occurred across all educational groups, with declines in e30 after 2011 for middle-educated males and low-educated females. Mortality trends among low-educated males (41.4%), middle-educated males (53.5%), and low-educated females (86.1%) contributed the most to the sex-specific stagnation. The observed increases in educational inequalities between 2011 and 2017 contributed approximately 27% to the national e30 stagnation.Widening educational inequalities, and particularly the unfavourable mortality trends observed for middle educated males and low educated females since 2011, contributed substantially to the e30 stagnation since 2011 in England & Wales.</p>","PeriodicalId":11907,"journal":{"name":"European Journal of Epidemiology","volume":" ","pages":"511-515"},"PeriodicalIF":7.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12170670/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144198589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we supplement our per-protocol analyses with instrumental variable (IV) estimates whose validity relies on an alternate set of assumptions but does not depend on the availability of confounder data. Individuals in the NordICC trial were randomized at a 1:2 ratio to receive either an invitation to a one-time screening colonoscopy (the invited group) or no invitation (the usual-care group).

Analyses included 28,220 participants in the invited group and 56,365 participants in the usual-care group. Participation in screening was 42%. In IV per-protocol analyses, the 10-year risk of colorectal cancer was 1.13% (95% confidence interval [CI]: 1.04, 1.23) with usual care and, depending on the assumptions, 0.66% (95% CI: 035, 0.95) to 0.74% (95% CI: 0.57, 0.95) in screened individuals (risk ratio of 0.59 [95% CI: 0.30, 0.98] to 0.65 [95% CI: 0.48, 0.87]).

Studies using transportability methods in a numerical application for at least partly non-overlapping source and target populations were included. We identified 3432 unique studies and included 64 studies applying transportability methods. Over two thirds of the included studies (44/64) introduced new methods. Less than one third of the included studies (20/64) were pure applications of transportability methods. Most applied studies (17/20) transported effect estimates from randomized controlled trials. Effects were transported to target populations with either complete (9/20) or no (9/20) treatment and outcome data or both (2/20). The most frequent aims of applied studies were to transport estimated effects to new populations (10/20) and to assess effect heterogeneity explainable by measured covariates (8/20). How transportability methods were applied varied widely between studies, for instance in the covariate selection approach and sensitivity analysis. Methodological studies with a transportability application presented new transportability estimators for randomized data (5/44), specific transportability applications (e.g., meta-analysis, mediation analysis; 21/44) and other methodological aspects (e.g., covariate selection, missing data handling; 18/44).
