Insights

Different intrauterine growth standards significantly impact the identification of newborns small for gestational age (SGA). The Lubchenco charts identify fewer SGA infants compared to other standards, highlighting the importance of selecting appropriate growth curves for accurate risk assessment.

Area of Science:

  • Neonatalogy
  • Pediatric Endocrinology
  • Public Health

Context:

  • Accurate assessment of intrauterine growth is crucial for identifying newborns at risk.
  • Population-specific growth standards are essential for evaluating infant well-being and nutritional status.
  • Variations in diagnostic criteria can affect the identification rates of small for gestational age (SGA) infants.

Purpose:

  • To analyze the differences in the number of small for gestational age (SGA) newborns identified using various population standards.
  • To evaluate the suitability of different intrauterine growth charts for a Caucasian newborn population.
  • To compare the performance of Olsen, Lubchenco, Delgado, and Carrascosa growth standards in identifying SGA infants.

Summary:

  • A cross-sectional study of 4,486 Caucasian newborns (35-41 weeks gestation) assessed weight and length against four different growth standards.
  • The Lubchenco curves showed significantly lower 10th percentile values for higher gestational ages and identified fewer SGA infants compared to Olsen, Delgado, and Carrascosa standards.
  • The percentage of SGA infants identified ranged from 1.7% to 14%, depending on the standard, sex, and gestational age, with Lubchenco charts demonstrating a poor fit for this population.

Impact:

  • The choice of intrauterine growth standard significantly influences the classification of SGA infants.
  • Lubchenco charts are less suitable for this population, potentially leading to underdiagnosis of SGA.
  • Accurate SGA identification is vital for timely intervention and managing short- and long-term health risks in newborns.

Nature and Nurture01:10

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...
Population Growth00:57

Population Growth

Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
z Scores and Area Under the Curve01:17

z Scores and Area Under the Curve

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 zero.
Bacterial Growth Curve01:28

Bacterial Growth Curve

The bacterial growth curve is a fundamental concept in microbiology that describes the dynamics of bacterial population growth in a closed system with controlled environmental conditions, such as temperature and nutrient availability. This curve is divided into four distinct phases: lag, log (exponential), stationary, and death phases, each reflecting a unique stage of bacterial adaptation and growth. During the lag phase, bacteria acclimate to their surroundings by synthesizing essential...
Regression Toward the Mean01:52

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...
