“…In contrast with the present findings, Dowding (1981) reported a clear association of social class on offspring birth weight in a study of singleton births during one year in Dublin. The Dublin study included stillbirths and infants who died early, and was based on a complete population, but did not control for smoking and parental size.…”

As part of a study on causes of variation in birth weight, questionnaire data on parental measures were related to offspring birth weights recorded in the Medical Birth Registry of Norway. A genetic analysis of parent-offspring covariances in birth weight indicated that about 60% of the variance in birth weight could be explained by effects of fetal genes, while no effects of maternal genes were detectable. Multiple regression analysis showed that height and weight of both parents and maternal smoking status were associated with variation in birth weight. Socioeconomic status, educational attainment and paternal smoking habit had no independent effects. The adult, parental variables could only explain 10% of the variation in mean offspring birth weight.

“…A significant association was found between lower maternal age at delivery, higher parity, number of abortions, anemia, low birthweight, SGAnewborns, and living in an area of lower social status. The results regarding maternal age and SGAnewborns are in accordance with the results of other investigators (1)(2)(3). Maternal life-style has been suggested as a possible cause of low birthweight infants which might be due to inadequate nutrition, smoking and the use of alcohol and narcotics during pregnancy (6,7).…”

“…According to DOWDING (1981), the increase in birth weight with increasing birth order is a social class effect. RUSH and CASSANO (1983), however, claim that the difference in birth weight found between social classes is determined by differences in smoking habits, a factor not adjusted for by DOWD-ING (1981).…”

Hansteen, I.‐L. Christophersen, N. and Langård, S. 1987. Surveillance of pregnancies as a means of detecting environmental and occupational hazards. II. Growth criteria including birth weight, length, and head circumference in a newborn population. —Hereditas 107 205–211. Lund, Sweden. ISSN 0018–0661. Received February 4, 1987 Birth weight, length and head circumference were recorded for liveborn children during a one year period in Telemark county, Norway, The county comprises both rural, urban and industrial areas. The purpose of the study was to see if there is an association between environmental and occupational exposure and the growth parameters affecting foetal development. Only single births of gestational age 37 weeks and more were compared. The present newborn population as a whole did not differ in mean weight, length and head circumference from the Norwegian newborn population at large. No effect of parental occupational exposure could be demonstrated. However, the power of detection was low. The area of residence seemed to affect the growth parameters even after correcting for gestational age, sex, birth order, mother's age, health and smoking habits, genetic factors, and to some extent for social class. The effects were most pronounced for later born children in the families. There was no increase in the three growth parameters from first to subsequently born children in the families living in the industrially exposed areas of residence, while the expected increase with parity was found in the two other areas of residence.
