Research objective: 

Hypothesis:
1) the risk of stillbirth increases with gestational age at term at a faster rate among women with high BMI, especially among obese women with additional risk factors such as advanced maternal age, assisted conception, hypertension and diabetes;
2) the optimal timing of delivery for overweight and obese women at term will depend on their BMI (degree of obesity) and additional risk factors such as advanced maternal age, assisted conception, hypertension and diabetes.

Objectives:
1) To determine the association between pre-pregnancy BMI and gestational age-specific rates of stillbirth, neonatal death (within 28 days after birth), and serious neonatal morbidity in Canada.
2) To determine the optimal timing of delivery for overweight and obese (class I, II, and III) women at term gestation (addressing modification of risk by advanced maternal age, assisted conception, hypertension and diabetes).
