Objective:
To determine the effect of inadequate gestational weight gain (GWG) on neonatal birth weight in diabetic obese women.
Study Design:
Retrospective cohort study of women with an initial body mass index (BMI) ⩾30 kg m(-2) and gestational or type 2 diabetes was conducted. GWG was stratified: inadequate (<11 lbs), adequate (11 to 20 lbs) or excessive (>20 lbs). The primary outcome was birth weight. Secondary outcomes included hypertensive disorders, gestational age at delivery, mode of delivery and Apgar scores.
Result:
A total of 211 obese diabetic women were identified. Of those, 37% had inadequate GWG, 25% had adequate GWG and 38% had excessive GWG. Women with inadequate GWG had lower mean birth weights (P=0.048), as well as lower rates of cesarean delivery (P=0.017) and lower rates of pregnancy-related hypertensive disorders (P=0.026) compared with those with adequate and excessive GWG.
Conclusion:
Inadequate GWG was associated lower mean birth weights, lower rates of cesarean delivery and lower rates of pregnancy-related hypertensive disorders.

Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
