Introduction: Maternal overweight is a major risk of gestational diabetes that can impair glycemic control. The objective of our study was to assess the impact of maternal weight status on glycemic control and pregnancy outcomes in patients followed for gestational diabetes.

Methods: Our work is a retrospective study, including 182 patients with gestational diabetes followed in the Endocrinology-Diabetology department between January 2016 and January 2022.

Results: The study included 182 patients with an average age of 32 years. The mean term at first visit was 21 weeks of amenorrhea (AS). The mean pregestational BMI was 29 kg/m². The average intake of weight was +6, 7 kg. all patients (n=7) with a BMI <18.5 kg/m²), were on a hygiene-dietetery diet, with a weight gain of +0.37 kg/SA. Those with a BMI between 18.5-24.9 kg/m², 85.71% (n=60) were on a hygiene-dietetery diet, with a weight gain of +0.39 kg/SA, 14.29% (n=10) on insulin. BMI between 25-29.9 kg/m² with a weight gain of + 0.4 kg/SA, 94.51% (n=86) observed insulin therapy, 5.49%(n=5) on a hygiene-dietetery diet. Patients with a BMI >30 kg/m2 with a weight gain of + 0.42 kg/SA were all on insulin. However, weight gain was significantly greater in patients treated with insulin than in those treated with a hygiene-dietetery diet (P=0.06).

Discussion: Maternal hyperglycemia during GDM was related to pregestational weight status and weight gain appeared to be a factor associated with insulin therapy. Hence the interest of raising awareness among patients from the prenatal consultation.
