The Role of Prenatal Care in Preventing Low Birth Weight

Abstract

Prenatal care has long been endorsed as a means to identify mothers at risk of delivering a preterm or growth-retarded infant and to provide an array of available medical, nutritional, and educational interventions intended to reduce the determinants and incidence of low birth weight and other adverse pregnancy conditions and outcomes. Although the general notion that prenatal care is of value to both mother and child became widely accepted in this century, the empirical evidence supporting the association between prenatal care and reduced rates of low birth weight emerged slowly and has been equivocal. Much of the controversy over the effectiveness of prenatal care in preventing low birth weight stems from difficulties in defining what constitutes prenatal care and adequate prenatal care use. While the collective evidence regarding the efficacy of prenatal care to prevent low birth weight continues to be mixed, the literature indicates that the most likely known targets for prenatal interventions to prevent low birth weight rates are (1) psychosocial (aimed at smoking); (2) nutritional (aimed at low prepregnancy weight and inadequate weight gain); and (3) medical (aimed at general morbidity). System level approaches to impact the accessibility and the appropriateness of prenatal health care services to entire groups of women and population-wide health promotion, social service, and case management approaches may also offer potential benefits. However, data on the effectiveness of these services are lacking, and whether interventions focused on building cohesive, functional communities can do as much or more to improve low birth weight rates as individualized treatments has yet to be explored. The ultimate success of prenatal care in substantially reducing current low birth weight percentages in the United States may hinge on the development of a much broader and more unified conception of prenatal care than currently prevails. Recommendations for actions to maximize the impact of prenatal care on reducing low birth weight are proposed both for the public and for the biomedical, public health, and research communities.

A Cost-Benefit Framework for Analyzing the Economic and Fiscal Impacts of State-Level Immigration Policies

“…The expected secondary impacts are shown in the second column of Table 3.17. In particular, research has demonstrated the importance of access to prenatal care services for the health of the mother and her child (Alexander and Korenbrot, 1995;Korenbrot et al, 2002;Rossin-Slater, 2015). For low-income women, the provision of subsidized care has been shown to reduce the incidence of low birth weight and lower infant mortality (Currie andGruber, 1996a, 1996b).…”

Low birth weight and health expenditures from birth to late adolescence

“…13 Patients need referrals from their GPs only for consultations with radiologists. 14 For the general role of prenatal care, see e.g., Alexander and Korenbrot (1995). 15 There is a strong financial incentive to take the exams, as eligibility for several family benefits depends on proof of participation.…”

Effect of nutrition education on exclusive breastfeeding for nutritional outcome of low birth weight babies

“…Previous evidence showed that maternal weight gain during pregnancy has a positive effect on birth weight of the neonate (Haughton et al, 1992;Alexander and Korenbrot, 1995;Viswanathan et al, 2008). In Bangladesh, National Nutrition Program Baseline Survey 2004 showed that only one-third women had gained more than 4 kg during the third trimester.…”
