ARE THE FACTORS AFFECTING ADVERSE PREGNANCY OUTCOMES DIFFERENT IN OBESE GESTATIONAL DIABETES PREGNANT WOMEN RECEIVING DIET OR INSULIN TREATMENT?

CONTEXT: We aimed to examine the factors affecting adverse gestational outcome in gestational diabetes (GDM) patients, who were grouped as obese and normal- weight, having only-diet, or insulin treatments. SUBJECTS AND METHODS: The study included 373 patients, treated with diet or insulin. These patients were sub-grouped as obese and non-obese, and examined retrospectively. The variables affecting adverse gestational outcome in obese GDM patients having dietary and/ or insulin treatments were detected with multiple regression analysis.
RESULTS: The weight gained during pregnancy in the GDM group having insulin treatment was more than the one in only-diet treated GDM group (p=0.004). Pre-pregnancy body mass index, the weight gained during pregnancy, hemoglobin A1C levels in the second and third trimesters, caesarian rates were higher in the insulin-treated obese patients than in the other groups (p<0.001). The odds ratio for fasting blood glucose level in insulin-treated obese GDM group was 1.081 (95% CI =1.004 - 1.163) (p=0.039); and it was 0.982 (95% CI =0.924 - 1.002) (p=0.048) for the weight gained during pregnancy, in only-diet treated obese GDM patients.
CONCLUSION: The control of weight gained during pregnancy, and of fasting blood glucose levels in obese patients having GDM, is important to decrease adverse gestational outcome. ©by Acta Endocrinologica Foundation.
