The relation of ethnic and selected socio‐economic factors to human birth‐weight *

The relation of ethnic and selected socio‐economic factors to human birth‐weight * BY ALFRED F. NAYLOR AND NTINOS C. MYRIANTHOPOULOS National Institute of Neurological Diseases and Blindness, National Institutes of Health, Bethesda, Maryland Among the biological variables which characterize the newborn, birth-weight occupies a unique position : it is universally present, has a continuous distribution and can be measured accurately. Birth-weight is an important indicator of the survival and future growth of the newborn. It is not surprising therefore that it has been extensively studied, especially from the obstetric and pediatric viewpoints, and that its relationships with other variables are being constantly investigated and reappraised. Investigations of the relative influences of various genetic and environmental factors on birthweight have shown that although foetal genetic constitution, including sex, is responsible for a large part of birth-weight variation, the most important component depends on maternal factors, both genetic and environmental (Donald, 1939; Karn & Penrose, 1951; Karn, LangBrown, MacKenzie & Penrose, 1951; Penrose, 1954a, b ; Morton, 1955). Veryfew attempts have been made to investigate the relations of socio-economic factors to birth-weight. Racial differencesin birth-weight are also well recognized.

Abstract

BY ALFRED F. NAYLOR AND NTINOS C. MYRIANTHOPOULOS National Institute of Neurological Diseases and Blindness, National Institutes of Health, Bethesda, Maryland Among the biological variables which characterize the newborn, birth-weight occupies a unique position : it is universally present, has a continuous distribution and can be measured accurately. Birth-weight is an important indicator of the survival and future growth of the newborn. It is not surprising therefore that it has been extensively studied, especially from the obstetric and pediatric viewpoints, and that its relationships with other variables are being constantly investigated and reappraised. Investigations of the relative influences of various genetic and environmental factors on birthweight have shown that although foetal genetic constitution, including sex, is responsible for a large part of birth-weight variation, the most important component depends on maternal factors, both genetic and environmental (Donald, 1939; Karn & Penrose, 1951; Karn, LangBrown, MacKenzie & Penrose, 1951; Penrose, 1954a, b ; Morton, 1955).
