Invited Commentary: Troubling Trends in Birth Weight
American Journal of Epidemiology
|December 16, 2015
Summary
Trends in newborn birth weights show a concerning decline, particularly widening the gap between white and African-American infants. This trend may indicate disparities in infant health outcomes.
Area of Science:
- Epidemiology
- Public Health
- Neonatal Health
Background:
- Birth weight is a critical indicator of newborn health.
- Previous studies highlight its predictive power for infant well-being.
Purpose of the Study:
- To analyze trends in birth weights over time.
- To investigate disparities in birth weights between racial groups.
Main Methods:
- Retrospective analysis of hospital birth records.
- Examination of birth weight data from 1997 to 2011.
Main Results:
- Observed a downward trend in average birth weights.
- Documented a widening disparity in birth weights between white and African-American newborns.
Conclusions:
- The declining birth weights and increasing racial gap raise significant public health concerns.
- These trends may reflect or predict divergent health outcomes for different racial groups.

01:52Regression Toward the Mean
7.3K
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...

01:14Fetal Circulation
4.5K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

01:17z Scores and Area Under the Curve
20.2K
z scores are the standardized values obtained after converting a normal distribution into a standard normal distribution. A z score is measured in units of the standard deviation. The z score tells you how many standard deviations the value x is above (to the right of) or below (to the left of) the mean, μ. Values of x that are larger than the mean have positive z scores, and values of x that are smaller than the mean have negative z scores. If x equals the mean, then x has a z score of...

01:09Apparent Weight
10.2K
True weight is the measure of the gravitational force acting on an object. However, if the object accelerates, its measured weight is different from its true weight. Similar observations can be made when the object is submerged in water. An object's weight in water is its apparent weight, which is equal to the difference between its true weight and the buoyant forces.

01:22Diabetes Mellitus: Type 2 and Gestational
5.5K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

01:28Development of the Oral Microbiota
25
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,...
