Exercise for diabetic pregnant women

Area of Science:

• Obstetrics and Gynecology
• Endocrinology
• Sports Medicine

Background:

• Diabetes in pregnancy poses risks to mothers and newborns.
• Exercise is a potential strategy to improve glycemic control during pregnancy.
• The impact of exercise on pregnancies with diabetes requires thorough assessment.

Purpose of the Study:

• To assess the effect of exercise programs on perinatal and maternal morbidity in pregnant women with diabetes.
• To compare exercise interventions with no specific program or other therapies.
• To evaluate the impact on insulin prescription rates for glycemic control.
• To compare the effectiveness of different exercise program types.

Main Methods:

• Searched the Cochrane Pregnancy and Childbirth Group's Trials Register for randomized controlled trials.
• Included trials evaluating exercise in pregnant women with diabetes.
• Assessed study inclusion criteria and methodological quality.
• Extracted data using intention-to-treat principle and calculated relative risks with 95% confidence intervals.

Main Results:

• Four trials with 114 pregnant women with gestational diabetes were reviewed; none included women with type 1 or type 2 diabetes.
• Interventions involved exercise for approximately six weeks, typically three times weekly for 20-45 minutes.
• No significant differences were found between exercise interventions and control groups for any evaluated outcomes.

Conclusions:

• Insufficient evidence exists to recommend or discourage exercise programs for pregnant women with diabetes.
• Further large-scale trials are necessary, including women with gestational diabetes and potentially type 1 and type 2 diabetes, to evaluate exercise interventions.
