Influence Of Pregnancy Weight On Maternal And Child Health

Influence of Pregnancy Weight on Maternal and Child Health: Workshop Report summarizes a one and a half day workshop convened in May 2006 that reviewed U.S. trends in maternal weight (prior to, during, and after pregnancy) among different populations of women; examined the emerging research findings related to the complex relationship of the biological, behavioral, psychological, and social interactions that affect maternal and pregnancy weight on maternal and child health outcomes; and discussed interventions that use this complex relationship to promote appropriate weight during pregnancy and postpartum. Given the unprecedented environment in the United States in which two-thirds of the adult population meets the criteria for being overweight or obese, the implications for women in the reproductive age period are unique in the history of the country. The concerns for maternal and infant health are real. The questions and answers tackled by committee members and workshop participants were not easy. Nevertheless, having an opportunity to explore what is known, examine the gaps in knowledge, and explore what to do now and in the future build a pathway for further inquiry and action. This report summarizes the workshop proceedings and highlights key themes that deserve further attention. The participants in this workshop describe what is known about recent trends in maternal weight gain and the impact of maternal weight during pregnancy on the health of mothers and their children. The workshop provided a valuable opportunity to assess trends that have occurred since the publication of an earlier study by the Institute of Medicine (IOM), which included guidelines for recommended weight gain during pregnancy.

As women of childbearing age have become heavier, the trade-off between maternal and child health created by variation in gestational weight gain has become more difficult to reconcile. Weight Gain During Pregnancy responds to the need for a reexamination of the 1990 Institute of Medicine guidelines for weight gain during pregnancy. It builds on the conceptual framework that underscored the 1990 weight gain guidelines and addresses the need to update them through a comprehensive review of the literature and independent analyses of existing databases. The book explores relationships between weight gain during pregnancy and a variety of factors (e.g., the mother's weight and height before pregnancy) and places this in the context of the health of the infant and the mother, presenting specific, updated target ranges for weight gain during pregnancy and guidelines for proper measurement. New features of this book include a specific range of recommended gain for obese women. Weight Gain During Pregnancy is intended to assist practitioners who care for women of childbearing age, policy makers, educators, researchers, and the pregnant women themselves to understand the role of gestational weight gain and to provide them with the tools needed to promote optimal pregnancy outcomes.

Since 1990, when the last guidelines for weight gain during pregnancy were issued, the average body weight of women entering their childbearing years has increased considerably, with a greater percentage of these women now classified as overweight or obese. Women of childbearing age are also more likely to have chronic conditions such as high blood pressure or diabetes and to be at risk for poor maternal and child health outcomes. All of these factors increase the likelihood of poor pregnancy outcomes for women and their infants. As part of the continuing effort of The Institute of Medicine (IOM) and the National Research Council (NRC) to promote the revised pregnancy weight gain guidelines recommended in their 2009 study Weight Gain During Pregnancy: Reexamining the Guidelines, the IOM and NRC convened a workshop in March, 2013, to engage interested stakeholders, organizations, and federal agencies in a discussion of issues related to encouraging behavior change that would reflect the updated guidelines on weight gain during pregnancy. During the workshop, the IOM and NRC presented newly developed information resources to support guidance based on the recommendations of the 2009 report. Leveraging Action to Support Dissemination of the Pregnancy Weight Gain Guidelines summarizes the workshop's keynote address and the various presentations and discussions from the workshop, highlighting issues raised by presenters and attendees. Interested stakeholders, organizations, health professionals, and federal agencies met to discuss issues related to encouraging behavior change that would reflect the updated guidelines on weight gain during pregnancy. This report discusses conceptual products as well as products developed for dissemination, ways to facilitate and support behavior change to achieve healthy weight pre- and postpregnancy, and how to put the weight gain guidelines into action to implement change.

Abstract: The nutritional status of the pregnant women is being recognized as one of the most important factors in the development of a baby, both pre and postnatally. Malnutrition can cause sterility, spontaneous aborption, stillbirth, premature birth, deformities and mental retardation. Statistics from many sources, such as European clinics during WWII and current figures from hospital observations all over the country, have been collected and compiled to provide information on prenatal and early childhood development in relation to nutrition in three ways--physiologically, neurologically, and behaviorally. Low birth weight is the measurement most closely associated with the incidence of neonatal disorders, and is shown to be closely related also to maternal nutrition. Reproductive casualties, particularly in regard to handicapped children, can be greatly decreased by better education and nourishment of expectant mothers.

There is no longer any doubt that the inherited genetic constitution of the individual has a large influence on the entire life cycle, from human fetal development and pre- and postnatal growth to subsequent health status. However, growing evidence suggests that this predisposition is not rigid, but that early genetic imprinting, caused by exposure to a diverse spectrum of nutrients, macromolecules, microbial agents and other cellular or soluble components present in the external environment, is also of importance. According to this concept of the developmental origins of adult diseases, intrauterine and early life events play an important role in the etiology of human diseases: there seems to exist a critical 'window of opportunity' in the human infant before and during pregnancy, and up to 24 months of age. Altered exposure to different environmental agents during this critical period may determine the nature of responses in the perinatal period, and the expression of specific disease states in later life. The papers presented in this publication thus focus on the impact of perinatal growth, nutrition, environmental microflora, and host immune responses on the outcome of health and disease in later life.

In pregnancy, maternal nutrition sustains and nourishes the developing child. Imbalances in either the direction of nutritional excess or deficiency can have adverse consequences for child health. In addition, more research now suggests that good pregnancy nutrition influences child health beyond pregnancy and delivery. This includes modifying the risk of child health outcomes as they enter childhood and adulthood through influences on placental development, hormonal pathways, and organ structure and function. Poor pregnancy nutrition may also compromise maternal health during pregnancy, which may have long-term consequences for women’s health. Understanding the biological and social mechanisms operating during pregnancy can help in the design of better clinical and public health interventions. This Special Issue on “The Role of Pregnancy Nutrition in Maternal and Offspring Health” includes etiological and mechanistic studies of pregnancy nutrition with short- and long-term maternal and child health outcomes, including original research, narrative reviews, and systematic reviews and meta-analyses. Together, this body of work provides important insights into the influence of dietary patterns, food groups, and nutrients on pregnancy outcomes, and long-term neurodevelopmental, respiratory, and metabolic health in the children. It also highlights nutritional consequences for specific groups of women, including those with pregnancy complications and eating disorders.

Authorities agree that nutritional care for pregnant, about-to-be pregnant, and nursing women can prevent health problems that are costly in terms of both dollars and quality of life. Yet many women still receive little guidance regarding maternal nutrition. Now, health care professionals can turn to a handy, practical guide for help in smoothly integrating maternal nutritional care into their practices. Nutrition During Pregnancy and Lactation provides physicians, nurses, primary care providers, and midwives with a ready-made, step-by-step program for helping new mothers. The guideâ€"based on the two most authoritative volumes available on the topic, both from the Institute of Medicineâ€"Nutrition During Pregnancy (1990) and Nutrition During Lactation (1991)â€"makes the findings and recommendations detailed in these books readily accessible for daily use. In keeping with recommendations by the U.S. Surgeon General, the guide promotes breastfeeding and includes practical information for mothers on how to breastfeed. Providing background details, resource lists, and a "toolbox" of materials, this implementation guide makes nutritional care simple and straightforward. Part I walks the health care professional through the process of providing nutritional advice for new mothersâ€"from the pre-pregnancy questionnaire to the final postpartum visit. It includes helpful tools such as weight charts and checklists to follow during each patient visit. It also offers suggestions on encouraging nutritional eating habits and helping patients with problems such as nausea and nursing twins. Part II offers a wide range of practical information and guidelines on important topics, such as serving culturally diverse populations, making dietary assessments throughout pregnancy and lactation, and providing dietary advice in understandable, day-to-day terms. The guide explains how to determine if patients need vitamin-mineral supplements and what regimens to recommend. And, it includes information on referring patients to federal food and nutrition programs. The guide is tabbed for quick reference and each page is designed for the reader to find information easily.
