Prepregnancy body mass index (BMI) is an independent predictor of many adverse outcomes of pregnancy. The prevalence of obesity in women 12 to 44 years of age has more than doubled

In 1999 to 2004, nearly two thirds of women of childbearing age were classified as overweight (BMI25) and almost one third were obese
(BMI 30).
