Qu X, et al. - Via obtaining data from the baseline survey of a large-scale cohort study in 10 diverse areas of China, researchers examined the connection between age at first childbirth and developing type 2 diabetes, and analyzed potential modifiers of its relationship. To analyze the link between developing type 2 diabetes and the age at first childbirth, multivariate logistic regressions were utilized. Compared to women who had their first child aged 25–29 years, those who delivered their first child aged <20 years were more strongly linked to developing type 2 diabetes later in life. Following adjustments for socioeconomic characteristics, lifestyle, reproductive factors and physiological risk factors, a significant inverse association remained at first birth with type 2 diabetes. Furthermore, it has been discovered that reproductive factors (ie, parity, menopause status), hypertension and BMI at age 25 have an impact on such an association.
