Objective: Assess and quantify the risk for gestational diabetes (GDM) according to pre-pregnancy maternal body mass index (BMI). Design: Systematic review of observational studies published in the last 30 years. Methods: Four electronic databases were searched for publications (1977- 2007).BMI was elected as the only measure of obesity and all diagnostic criteria for GDM were accepted. Studies with selective screening for GDM were excluded. There were no language restrictions. The methodological quality of primary studies was assessed. Results: 1745 citations were screened and 70 studies (2 unpublished) involving 671,945 women were included (59 cohorts and 11 case-controls). Most studies (81.4%) were of medium or high quality. Compared to women with a normal BMI, the unadjusted pooled OR of an underweight woman developing GDM was 0.75 (95% CI 0.69 to 0.82). The OR for women with overweight, class I and class II to III obesity were 1.97 (95% CI 1.77 to 2.19), 3.01 (95% CI 2.34 to 3.87) and 5.55 (95% CI 4.27 to 7.21), respectively. For every 1 kg/m2 increase in BMI, the prevalence of GDM increased by 0.92% (95% CI 0.73 to 1.10). Conclusions: The risk of GDM is directly associated with pre-pregnancy BMI. This information is important when counseling women planning a pregnancy.
