Fetal growth in different racial groups.

J Alvear, O G Brooke

    Archives of Disease in Childhood
    |January 1, 1978
    PubMed
    Summary

    Maternal race impacts fetal size, with Indian-Asian infants being lighter and having smaller circumferences than European or Negro infants. Maternal smoking showed no effect on fetal development in this study.

    Cigarette smoking and birthweight: type of cigarette smoked and a possible threshold effect.

    International journal of epidemiology·1991

    Area of Science:

    • Anthropometry
    • Human Genetics
    • Perinatal Studies

    Background:

    • Maternal race and smoking are potential factors influencing fetal growth.
    • Previous research indicates variations in birth weight across different ethnic groups.
    • The impact of maternal smoking on fetal anthropometry requires further investigation.

    Purpose of the Study:

    • To investigate the effects of maternal race and smoking on fetal size and anthropometric measurements.
    • To compare anthropometric data of newborns from North European, Negro, and Indian-Asian mothers.
    • To assess the correlation between maternal smoking habits and fetal development.

    Main Methods:

    • Matched cohort study design involving three racial groups: North European, Negro, and Indian-Asian mothers and their newborns.
    • Collection of anthropometric data including skinfold thickness, limb circumferences, and linear measurements from mothers and infants.
    • Matching of participants based on parity, gestational age, sex, maternal age, smoking habits, and social class.

    Main Results:

    • Indian-Asian infants were lighter with smaller head and limb circumferences compared to European and Negro infants, despite similar maternal anthropometry and weight gain.
    • Negro and European infants exhibited nearly identical anthropometric measurements.
    • No statistically significant effect of maternal smoking on any fetal anthropometric measurements was observed.

    Conclusions:

    • Maternal race is a significant determinant of fetal size and anthropometry, independent of maternal physical characteristics and pregnancy weight gain.
    • Maternal smoking does not appear to influence fetal size or anthropometric development in the studied population.
    • Further research is warranted to explore the genetic and environmental factors contributing to racial differences in fetal growth.
