This prospective cohort study enroled 10232 Japanese adults aged ≥65 years, who underwent follow-up for adverse events, from the Kyoto-Kameoka Study conducted from 2011–2016. BMI, calculated based on self-reported height and body weight, was classified into five categories: <18.5, 18.5–21.4, 21.5–24.9, 25.0–27.4, and ≥27.5 kg/m2. Frailty was assessed using the validated Kihon Checklist. The relationships between BMI and disability and mortality were analysed using multivariate Cox proportional hazards models and Laplace regression. During the 5.3-year median follow-up period (45472 person-years), 2348 (22.9%) incidences of disabilities occurred. After adjusting for confounders, including medical history and lifestyle, individuals in the lowest and highest BMI categories had a higher hazard ratio (HR) of disability [<18.5 kg/m2: HR: 1.31, confidence interval (CI): 1.16–1.49; ≥27.5 kg/m2: HR: 1.27, 95% CI: 1.08–1.49, p for non-linearity <0.001] compared with that of those with BMI = 21.5–24.9 kg/m2. In the 50th percentile differences in age at overall and disability-free survival, participants with BMI < 18.5 kg/m2 were more likely to die before disability incidence [survival with disability (overall survival – disability-free survival): −10.2 months]; those with BMI ≥ 27.5 kg/m2 had longer survival with disability (12.5 months). These relationships were more marked in the frailty-stratified model, where in the BMI ≥ 27.5 kg/m2 group, individuals with frailty survived longer with disability (27.2 months) than did individuals without frailty (6.2 months). Higher BMI is associated with a longer duration of survival with disability among older adults, especially in those with frailty. Therefore, reversing frailty should be prioritised because individuals with frailty have a shorter probability of disability-free survival than do individuals without frailty, regardless of BMI.","PeriodicalId":14183,"journal":{"name":"International Journal of Obesity","volume":"49 2","pages":"348-356"},"PeriodicalIF":4.2,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41366-024-01681-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142638938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering its significant association with lower socioeconomic status, implementing obesity prevention programs in vulnerable school-age children is particularly pertinent.

The BeE-school study involved 735 children (51.7% boys, average age 7.7 (1.2) years old) from 10 primary schools in the Northern region of Portugal, identified as Educational Territories for Priority Intervention. After the initial assessment, the schools were randomized into two groups: one receiving the intervention (4 schools, n = 353) and the other not (6 schools, n = 382). The intervention included education and training teachers for 16 weeks, their implementation in the classroom, and giving families challenges every two weeks during this length of time. The program’s effectiveness was assessed short-term, immediately post-intervention (for 95.5% of participants) and long-term, one year after (for 50.8%).
