We used a multivariable Cox regression model to assess the excess risk of CKD and ESKD in children with LBW/preterm/SGA. They were followed from birth until the occurrence of outcomes or until 31 December 2018, with an average follow-up of 5.78 years.</p><p><strong>Results: </strong>This study included 1 361 071 infants with birth weight ≥2500 g (92.14%), 104 855 infants with low birth weight (1500 g to <2500 g) (7.10%), 6843 infants with very low birth weight (1000 g to <1500 g) (0.46%) and 4349 infants with extremely low birth weight (<1000 g) (0.29%). The multivariable-adjusted model showed that male infants with low birth weight were associated with an increased risk of CKD [adjusted hazard ratio (aHR) 1.20, 95% confidence interval (CI) 1.08-1.32] and ESKD (aHR 1.64, 95% CI 1.37-1.97). Female infants with LBW had an increased risk of CKD (aHR 1.18, 95% CI 1.06-1.32) and ESKD (aHR 1.31, 95% CI 1.09-1.58) than those without LBW. In addition to LBW, infants with preterm or SGA condition also had a significantly and synergistically increased risk of CKD and ESKD compared with full-term infants.</p><p><strong>Conclusion: </strong>We found children with LBW, preterm birth or SGA had a significantly increased risk of CKD and ESKD compared with children without intrauterine growth restriction.</p>","PeriodicalId":19078,"journal":{"name":"Nephrology Dialysis Transplantation","volume":" ","pages":"1550-1558"},"PeriodicalIF":5.6,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143053028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
