Maternal weight characteristics influence recurrence of fetal macrosomia in women with normal glucose tolerance

This study examines the relationship between maternal weight characteristics and recurrence of macrosomia in 111 non‐diabetic women who delivered a second baby following primiparous delivery of a macrosomic infant (> 4500 g). Recurrence of fetal macrosomia was associated with greater maternal body mass index (P = 0.032), greater initial pregnancy weight (P < 0.05) and total weight gain during second pregnancy (P < 0.01). Women delivering a first macrosomic infant should avoid excessive weight gain before and during a subsequent pregnancy.
