^a unadjusted

^b After adjusted for age, pre-pregnancy body mass index, and parity (nulliparous/multiparous)

^c After adjusted for age, pre-pregnancy body mass index, parity (nulliparous/multiparous), daily intake of vegetables, fruits, seafood, and nuts

Logistic regression analysis method was used. A P-value below 0.05 was considered statistically significant
