A prospective study of relationship between abnormal glucose metabolism during pregnancy and family history of diabetes / 中国糖尿病杂志

ABSTRACT

Objective To study the relationship of gestational diabetes mellitus(GDM) and ~family history of diabetes (FHD), clinical characteristics and maternal and infant outcomes of GDM and gestational impaired glucose tolerance (GIGT). Methods A prospective case-control study was performed in 244 women with GDM/ GIGT, including 93 patients with family history of diabetes and 151 without FHD, and 244 normal OGTT cases as control from Feb. 2004 to Aug. 2004 in Dept of OB &GYN of Peking University First Hospital. Univariate analysis was used to estimate the odds ~ratios with 95% CI. Results (1)FHD was a risk factor of GDM/GIGT, OR=2.9.The co-effect of parents DM on transmission was excessive. (2)Maternal≥30 years old with FHD were greater than those without FHD (75.3% vs 62.9%). More intakes of fruits and carbohydrate per day and more weight gain during pregnancy in pregnant women with FHD were lower than those in patients without FHD. (3) The prevalence of GDM was indifferent ~between patients with and without FHD. 50 g OGCT plasma glucose (PG), fasting PG and 3 h PG in 75 g OGTT of patients with FHD were higher than those of patients without FHD. The number of pregnant women treated by insulin was significantly different between patients with and without FHD. (4) No difference was found between family and non-family history of diabetes in the prevalences of pre-eclampsia, FGR, polyhydramnios, preterm labor, LGA and SGA. Conclusions (1) FHD is a risk of GDM/GIGT, and exposure to a diabetic intrauterine environment is a mechanism responsible for this excessive maternal inheritance. (2)~Besides family history of diabetes, more intake of fruits or carbohydrate and larger gain of body weigh during pregnancy may result in GDM/GIGT.
