摘要

The authors aim to investigate the GDM and the dose-response association of BMI with it in pregnant women in Kermanshah, Iran. During the 2015-2016 year, the 1010 pregnant women were studied. The restricted cubic spline method was used to evaluate the relationship between BMI and GDM. The risk of GDM was 10.1%. The incidence rate ratio for GDM indicates a non-significant protective effect and, then a significant risk for GDM occurrence along with BMI. BMI can be used as a predictive factor. A healthy diet and recommended levels of physical activity are suggested to prevent overweight and obesity and subsequent GDM.
