Note: IVF = in vitro fertilization; IQR = interquartile range; MVPA = moderate to vigorous physical activity.

P values from Wilcoxon-Mann-Whitney nonparametric test.

For self-reported past year physical activity, each component index could range from 1 (lower physical activity) to 5 (higher physical activity) and the total activity index from 4 to 20.
