GDM was identified based on impaired oral glucose tolerance test results according to the guidelines of the International Association of the Diabetes and Pregnancy Study Groups. Associated factors for GDM were analyzed using a modified Poisson regression with robust (sandwich) SE analysis, with maternal age, prepregnancy BMI, and family history of diabetes as explanatory factors, adjusted for parity, method of conception, hormonal therapy for pregnancy maintenance, physical inactivity, and history of chronic medical conditions.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The prevalence of GDM was 26.2%. Patients with GDM were more likely to be older than the control group (odds ratio 3.33, 95% CI 2.31\u20104.78). In the multivariable analysis, maternal age was strongly associated with GDM. Compared with women aged <25 years, those aged 25 to 34 years had a significantly higher prevalence of GDM (adjusted prevalence ratio [PR] 1.50, 95% CI 1.12\u20101.99;\n P<\/jats:italic>\n =.006). The rate was even higher among women aged \u226535 years (adjusted PR 2.40, 95% CI 1.74\u20103.31;\n P<\/jats:italic>\n <.001). These associations remained consistent after further adjustment for confounders (25\u201034 years: adjusted PR 1.44, 95% CI 1.07\u20101.95;\n P<\/jats:italic>\n =.02 and \u226535 years: adjusted PR 2.15, 95% CI 1.49\u20103.11;\n P<\/jats:italic>\n <.001). Overweight women (BMI 23 to <25 kg\/m\u00b2) showed a borderline association with GDM, although this did not reach statistical significance (adjusted PR 1.39, 95% CI 0.98\u20101.98;\n P<\/jats:italic>\n =.06), while women with BMI \u226525 kg\/m\u00b2 had a significantly higher prevalence (adjusted PR 1.58, 95% CI 1.10\u20102.26;\n P<\/jats:italic>\n =.01). These findings persisted in the adjusted model, with BMI \u226525 kg\/m\u00b2 remaining significantly associated with GDM (adjusted PR 1.54, 95% CI 1.10\u20102.17;\n P<\/jats:italic>\n =.01). Women with a family history of diabetes had an increased prevalence of GDM in both models, although the association did not reach statistical significance (adjusted PR 1.51, 95% CI 0.85\u20102.68;\n P<\/jats:italic>\n =.16). Most additional covariates included in the multivariable analysis were not significant. However, women who conceived via in vitro fertilization had a significantly higher prevalence of GDM compared with those who conceived naturally (adjusted PR 1.38, 95% CI 1.04\u20101.85;\n P<\/jats:italic>\n =.03). The use of hormonal therapy to maintain pregnancy was also associated with an increased risk (adjusted PR 1.32, 95% CI 1.04\u20101.68;\n P<\/jats:italic>\n =.02).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The findings highlight the need for early screening and counseling before pregnancy. Lifestyle programs should focus on weight control and healthy habits. Future research should test whether these programs can reduce the rate of GDM in rural communities.<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/79688","type":"journal-article","created":{"date-parts":[[2026,3,31]],"date-time":"2026-03-31T17:42:45Z","timestamp":1774978965000},"page":"e79688-e79688","source":"Crossref","is-referenced-by-count":0,"title":["Gestational Diabetes Mellitus and Associated Factors in Rural Areas of Northern Vietnam: Cross-Sectional Survey"],"prefix":"10.2196","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6799-1422","authenticated-orcid":false,"given":"Duc Cuong","family":"Le","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-2656-5508","authenticated-orcid":false,"given":"Thi Hien","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6010-4096","authenticated-orcid":false,"given":"Thi Ly","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-5588-3288","authenticated-orcid":false,"given":"Thi Nuong","family":"Tran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0814-743X","authenticated-orcid":false,"given":"Xuan Hien","family":"Luong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-9016-3664","authenticated-orcid":false,"given":"Thi Thu Huong","family":"Do","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-8057-0902","authenticated-orcid":false,"given":"Xuan Thuy","family":"Tran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-8619-6224","authenticated-orcid":false,"given":"Van Manh","family":"Ngo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2043-4135","authenticated-orcid":false,"given":"Thi Huyen Dieu","family":"Bui","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9022-1170","authenticated-orcid":false,"given":"Tien Van","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1369-8615","authenticated-orcid":false,"given":"Van Thuan","family":"Hoang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6841-8663","authenticated-orcid":false,"given":"Thanh Binh","family":"Vu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2026,3,31]]},"reference":[{"issue":"1","key":"R1","doi-asserted-by":"publisher","DOI":"10.1007\/s11892-015-0699-x","article-title":"Prevalence of gestational diabetes and risk of progression to type 2 diabetes: a global perspective","volume":"16","author":"Zhu","journal-title":"Curr Diab Rep"},{"issue":"10","key":"R2","doi-asserted-by":"publisher","first-page":"1005","DOI":"10.1001\/jama.2018.11628","article-title":"Association of gestational diabetes with maternal disorders of glucose metabolism and childhood adiposity","volume":"320","author":"Lowe","journal-title":"JAMA"},{"issue":"11","key":"R3","doi-asserted-by":"publisher","DOI":"10.3390\/ijms19113342","article-title":"The pathophysiology of gestational diabetes mellitus","volume":"19","author":"Plows","journal-title":"Int J Mol Sci"},{"key":"R4","doi-asserted-by":"publisher","DOI":"10.2337\/diacare.26.2007.s5","article-title":"Report of the Expert Committee on the diagnosis and classification of diabetes mellitus","volume":"26 Suppl 1","author":"Expert Committee on the Diagnosis and Classification of Diabetes Mellitus","journal-title":"Diabetes Care"},{"key":"R5","unstructured":"Gestational diabetes.
