Following the 2009 American Institute of Medicine recommendations for normal body mass index and overweight women led to an increased risk of fetal macrosomia among Taiwanese women

Abstract

Objective: This study aimed to investigate the risk of birth weights over 4000 g (macrosomia) in association with following the 2009 American Institute of Medicine (AIOM) recommendations. Materials and Methods: Seventy-six nondiabetic women who delivered a singleton, term macrosomic fetus and 82 women who delivered a singleton, term fetus weighing 1000 mL at delivery (35.5% vs. 6.1%, p 11.5 kg, the risk of macrosomia increased nine-fold (OR = 9.63; 95% CI 1.76–52.74). Conclusion: Macrosomia resulted in more cesarean deliveries and greater maternal blood loss at birth. In Taiwan, to prevent macrosomia, we suggest that the total gestational weight gain should be <11.5 kg among normal weight women and within 10 kg for overweight women.
