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 Results The incidence of macrosomia from January 2008 to December 2009 was 1.8% among the Taiwanese women. The incidences of cesarean delivery (54.5% vs. 18.2%, p 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
