Objective? To study the incidence of gestational diabetes in women of advanced maternal age and to perform Logistic analysis of the contributing factors. Methods? A total of 180 elderly pregnant women admitted to Affiliated Hospital of Jiangnan University from July 2017 to February 2020 were selected. All of them were tested for blood glucose indicators，medical record data were collected，and then the incidence of gestational diabetes of advanced maternal age was counted，Logistic analysis was performed for the influencing factors of gestational diabetes. Results? Among the 180 elderly women，the incidence of gestational diabetes was 18.89%. The pre-pregnancy quality index（BMI），high pregnancy weight gain，abortion frequency≥2 times，family history of diabetes，eating sweets，anxiety and hyperhemoglobinemia are all worse than those without gestational diabetes.The proportion of high and daily exercise≥1 h was lower（P＜0.05）. Logistic multivariate analysis，prepregnancy BMI，weight gain during pregnancy，≥2 times of abortion were risk factors for gestational diabetes in older women（OR＞1，P＜ 0.05）；the daily exercise volume ≥1 h was the protective factor for the occurrence of gestational diabetes in elderly women（OR＜1，P＜0.05）. Conclusion Pregnancy weight gain，family history of diabetes，and eating sweets are risk factors for gestational diabetes in older women. The daily exercise volume≥1 h is a protective factor and contributes to the development of preventive measures.
