    Insights

    Low birthweight is more common in African countries, primarily due to environmental factors and a higher rate of multiple births. However, healthy African mothers have babies with birthweights similar to Caucasian babies.

    Area of Science:

    • Global Health
    • Perinatal Epidemiology
    • Human Genetics

    Background:

    • Low birthweight (LBW) prevalence is notably higher in many African nations compared to developed countries.
    • A significant contributor to LBW in Africa is the increased incidence of babies born small for gestational age (SGA).
    • Mean birthweights across various gestational ages are generally lower for African infants.

    Purpose of the Study:

    • To investigate the factors contributing to the higher prevalence of low birthweight in African populations.
    • To compare birthweights of African infants with those in developed countries, considering gestational age.
    • To differentiate the roles of environmental and genetic factors in infant birthweight.

    Main Methods:

    • Comparative analysis of birthweight data from African countries and developed nations.
    • Assessment of factors such as gestational age, environmental influences, and twinning rates.
    • Examination of birthweights in infants born to mothers with optimal health status.

    Main Results:

    • Environmental factors are identified as the primary drivers of lower mean birthweights in African infants.
    • An increased prevalence of twinning is recognized as a contributing genetic factor.
    • When maternal health is optimal, birthweights for gestational age in African infants are comparable to Caucasian infants.

    Conclusions:

    • Environmental factors significantly impact birthweight in African populations.
    • While genetic factors like twinning play a role, environmental influences are more dominant.
    • Optimizing maternal health may mitigate the disparity in birthweight between African and Caucasian infants.

    Nature and Nurture

    Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...

    Anatomy of the Intestines

    Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
    Small Intestines
    The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...

    Regression Toward the Mean

    Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...

    Development of the Oral Microbiota

    The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
