Backward stepwise logistic regression. Variables eliminated from the model were Parity; Marital status; Employment status and Education. Hosmer-Lemeshow fitness P-value=0.651 (chi-square=5.96, df=8). Dependent variable is meeting IOM recommendations for weight gain by pre-pregnancy BMI status: 0 = meeting and 1 = not meeting IOM recommendation (gaining excess).
