Epidemiological and experimental studies indicate that
environmental conditions before birth and during early postnatal life can
influence organ development and thereby long-term health. Different organs vary
in their susceptibility to early-life stressors. For example, the brain, heart,
and kidneys are often particularly affected, while some postnatal interventions
may partially mitigate deficits.

Which pattern of findings would provide the strongest
support for the Barker Hypothesis?

Accepted Answer

Individuals
exposed to maternal undernutrition during gestation exhibit reduced nephron
number, altered cardiovascular physiology, and increased adult disease risk,
with sex-specific differences in severity

Answer

Adult
disease risk is primarily determined by genetics, with little influence from
prenatal or early postnatal environment

Answer

Low
birth weight infants of both sexes show uniform adult disease outcomes, and
early postnatal nutrition fully restores organ function

Answer

Accelerated
postnatal weight gain eliminates all developmental deficits caused by prenatal
stress, without sex differences
