Adolescents who were aged 16 to 20 years; born since January 1, 1975; medically evaluated for mandatory military service through December 31, 2019; and insured by Maccabi Healthcare Services were assessed. Individuals with kidney pathology, albuminuria, hypertension, dysglycemia, or missing blood pressure or BMI data were excluded. Body mass index was calculated as weight in kilograms divided by height in meters squared and categorized by age- and sex-matched percentiles according to the US Centers for Disease Control and Prevention. Follow-up started at the time of medical evaluation or January 1, 2000 (whichever came last), and ended at early CKD onset, death, the last day insured, or August 23, 2020 (whichever came first). Data analysis was performed from December 19, 2021, to September 11, 2023.<\/jats:p><\/jats:sec>Main Outcomes and Measures<\/jats:title>Early CKD, defined as stage 1 to 2 CKD by moderately or severely increased albuminuria, with an estimated glomerular filtration rate of 60 mL\/min\/1.73 m2<\/jats:sup> or higher.<\/jats:p><\/jats:sec>Results<\/jats:title>Of 629\u202f168 adolescents evaluated, 593\u202f660 (mean [SD] age at study entry, 17.2 [0.5] years; 323\u202f293 [54.5%] male, 270\u202f367 [45.5%] female) were included in the analysis. During a mean (SD) follow-up of 13.4 (5.5) years for males and 13.4 (5.6) years for females, 1963 adolescents (0.3%) developed early CKD. Among males, the adjusted hazard ratios were 1.8 (95% CI, 1.5-2.2) for adolescents with high-normal BMI, 4.0 (95% CI, 3.3-5.0) for those with overweight, 6.7 (95% CI, 5.4-8.4) for those with mild obesity, and 9.4 (95% CI, 6.6-13.5) for those with severe obesity. Among females, the hazard ratios were 1.4 (95% CI, 1.2-1.6) for those with high-normal BMI, 2.3 (95% CI, 1.9-2.8) for those with overweight, 2.7 (95% CI, 2.1-3.6) for those with mild obesity, and 4.3 (95% CI, 2.8-6.5) for those with severe obesity. The results were similar when the cohort was limited to individuals who were seemingly healthy as adolescents, individuals surveyed up to 30 years of age, or those free of diabetes and hypertension at the end of the follow-up.<\/jats:p><\/jats:sec>Conclusions and Relevance<\/jats:title>In this cohort study, high BMI in late adolescence was associated with early CKD in young adulthood. The risk was also present in seemingly healthy individuals with high-normal BMI and before 30 years of age, and a greater risk was seen among those with severe obesity. These findings underscore the importance of mitigating adolescent obesity rates and managing risk factors for kidney disease in adolescents with high BMI.<\/jats:p><\/jats:sec>","DOI":"10.1001\/jamapediatrics.2023.5420","type":"journal-article","created":{"date-parts":[[2023,12,11]],"date-time":"2023-12-11T16:08:47Z","timestamp":1702310927000},"page":"142","source":"Crossref","is-referenced-by-count":40,"title":["Adolescent Body Mass Index and Early Chronic Kidney Disease in Young Adulthood"],"prefix":"10.1001","volume":"178","author":[{"given":"Avishai M.","family":"Tsur","sequence":"first","affiliation":[{"name":"Israel Defense Forces, Medical Corps, Tel Hashomer, Ramat Gan, Israel"},{"name":"Department of Military Medicine, Hebrew University of Jerusalem Faculty of Medicine, Jerusalem, Israel"},{"name":"Department of Medicine, Sheba Medical Center, Tel HaShomer, Israel"},{"name":"Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Inbal","family":"Akavian","sequence":"additional","affiliation":[{"name":"Israel Defense Forces, Medical Corps, Tel Hashomer, Ramat Gan, Israel"},{"name":"Department of Military Medicine, Hebrew University of Jerusalem Faculty of Medicine, Jerusalem, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Regev","family":"Landau","sequence":"additional","affiliation":[{"name":"Israel Defense Forces, Medical Corps, Tel Hashomer, Ramat Gan, Israel"},{"name":"Department of Military Medicine, Hebrew University of Jerusalem Faculty of Medicine, Jerusalem, Israel"},{"name":"Department of Medicine, Sheba Medical Center, Tel HaShomer, Israel"},{"name":"Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Estela","family":"Derazne","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dorit","family":"Tzur","sequence":"additional","affiliation":[{"name":"Israel Defense Forces, Medical Corps, Tel Hashomer, Ramat Gan, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asaf","family":"Vivante","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel"},{"name":"Department of Pediatrics B and Pediatric Nephrology Unit, Edmond and Lily Safra Children\u2019s Hospital, Sheba Medical Center, Tel Hashomer, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ehud","family":"Grossman","sequence":"additional","affiliation":[{"name":"Department of Medicine, Sheba Medical Center, Tel HaShomer, Israel"},{"name":"Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ran S.","family":"Rotem","sequence":"additional","affiliation":[{"name":"Maccabitech Institute for Research and Innovation, Maccabi Healthcare Services, Tel Aviv, Israel"},{"name":"Department of Environmental Health, Harvard T.H.
