    Position of the Academy of Nutrition and DIetetics: Obesity, Reproducton and Pregnancy Outcomes
    Abstract:
     It is the position of the Academy of Nutrition and Dietetics that all women of reproductive age receive education about maternal and fetal risks associated with prepregnancy obesity, excessive gestational weight gain, and significant postpartum weightretention, including potential benefits of lifestyle changes. Behavioral counseling to improve dietary intake and physical activity should be provided to overweight and obese women, beginning in the preconception period and continuing throughout pregnancy, for at least 12 to 18 months postpartum. Weight loss before pregnancy may improve fertility and reduce the risk of poor maternalfetal outcomes, such as preterm birth, gestational diabetes, gestational hypertension, pre-eclampsia, assisted delivery, and select congenital anomalies. Lifestyle interventions that moderate gestational weight gain may reduce the risk of poor pregnancy outcomes, such as gestational diabetes, gestational hypertension, large for gestational age, and macrosomia, as well as lower the risk for significant postpartum retention. Postpartum interventions that promote healthy diet and physical activity behaviors may reduce postpartum weight retention and decrease obesity-related risks in subsequent pregnancies. Analysis of the evidence suggests that there is good evidence to support the role of diet, physical activity, and behavior changes in promoting optimal weight gain during pregnancy; however, there is currently a relative lack of evidence in other areas related to reproductive outcomes.J Acad Nutr Diet. 2016;116:677-691 (PDF)


    Position of the American Dietetic Association and American Society of Nutrition: Obesity, Reproduction, and Pregnancy Outcomes
    Abstract: Given the detrimental influence of maternal overweight and obesity on reproductive and pregnancy outcomes for the mother and child, it is the position of the American Dietetic Association and the American Society for Nutrition that all overweight and obese women of reproductive age should receive counseling on the roles of diet and physical activity in reproductive health prior to pregnancy, during pregnancy, and in the interconceptional period, in order to ameliorate these adverse outcomes. The effect of maternal nutritional status prior to pregnancy on reproduction and pregnancy outcomes is of great public health importance. Obesity in the United States and worldwide has grown to epidemic proportions with an estimated 33% of US women being classified as obese. This position paper has two objectives: (a) to help nutrition professionals become aware of the risks and possible complications of overweight and/or obesity for fertility, the course of pregnancy, birth outcomes, and short- and long-term maternal and child health outcomes; and (b)  related to the American Dietetic Association's and the American Society for Nutrition's commitment to research, to identify the gaps in research to improve our knowledge of the risk and complications associated with being overweight and obese prior to and during pregnancy. Only with an increased knowledge of these risks and complications, can health care professionals develop effective strategies that can be implemented prior to and during pregnancy as well as during the interconceptional period to ameliorate adverse outcomes.  J Am Diet Assoc. 2008;109:918-927 (PDF)
