No significant association was found between serum TMAO and GDM odds. In addition, the stratified analysis results showed that among women with abnormal weight gain during pregnancy, there was a significant inverse association between serum betaine and GDM odds [OR (95% CI), 0.26 (0.13, 0.57)].</p><p><strong>Conclusion: </strong>Serum choline and betaine, but not TMAO, tend to be inversely associated with GDM odds among Han Chinese women with singleton gestation. Especially among those women with abnormal weight gain during pregnancy, higher serum betaine was associated with lower GDM likelihood.</p>","PeriodicalId":36307,"journal":{"name":"BMJ Nutrition, Prevention and Health","volume":"8 1","pages":"e001111"},"PeriodicalIF":2.5,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12322560/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144795739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
