We requested data from all eligible cohorts that agreed to participate in the study. Linear mixed models were used to investigate associations between age and thyroid function, stratified for sex and regional iodine status. Annual changes in thyroid-stimulating hormone (TSH) and free thyroxine (FT<sub>4</sub>) were estimated per individual and categorised into quintiles, with the highest and lowest quintiles defined as increasing and decreasing, respectively, and the rest as stable.

Cross-sectionally, older age was associated with higher TSH in iodine-sufficient regions and with lower TSH in iodine-insufficient regions. Longitudinal analyses showed that TSH increased with increasing age regardless of iodine status. The overall increase in TSH from age 18 years to 100 years was 0·61 mIU/L (0·52 SD) for female participants and 0·99 mIU/L (0·76) for male participants from iodine-sufficient regions. Greater variability in population distribution and longitudinal TSH changes was observed in adults aged 65 years or older. Higher FT<sub>4</sub> with older age was suggested cross-sectionally, but longitudinally FT<sub>4</sub> increased in iodine-sufficient regions and decreased in iodine-insufficient regions. Compared with stable thyroid function, all changing patterns were associated with increased all-cause mortality: hazard ratios of 1·80 (95% CI 1·57-2·06) for increasing TSH with stable or decreasing FT<sub>4</sub>; 2·45 (2·01-2·97) for increasing TSH and increasing FT<sub>4</sub>; 2·45 (1·99-3·01) for decreasing TSH with decreasing FT<sub>4</sub>; and 1·94 (1·68-2·24) for decreasing TSH with stable or increasing FT<sub>4</sub>.</p><p><strong>Inter","PeriodicalId":48790,"journal":{"name":"The Lancet Diabetes & Endocrinology","volume":" ","pages":""},"PeriodicalIF":41.8,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147822549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also identify major gaps in surveillance systems, research capacity, prevention, and clinical management across the region. Sub-Saharan Africa is experiencing one of the fastest global increases in diabetes, with the highest proportion of undiagnosed cases and a projected steep rise in intermediate hyperglycaemia and diabetes by 2050. Urbanisation, ageing, obesity, and lifestyle transitions are major contributors; however, a substantial proportion of type 2 diabetes occurs in lean individuals (BMI <25 kg/m<sup>2</sup>), particularly in rural settings, suggesting distinct metabolic and developmental pathways not captured by models derived from high-income countries. Bidirectional interactions between diabetes and malaria, tuberculosis, HIV, or COVID-19 make disease trajectories complex. Persistent gaps in surveillance, a reliance on modelled estimates, low genomic representation, and constrained access to modern diabetes medications hinder progress.
