The Barker Hypothesis, also known as the Developmental
Origins of Health and Disease (DOHaD) framework, proposes that adverse
environmental conditions during critical periods of development permanently
alter organ structure, physiology, and metabolic regulation. These changes may
not be immediately apparent at birth but can predispose individuals to
cardiovascular, renal, and metabolic diseases later in life.

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

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

Accepted Answer

Prenatal
undernutrition leads to lasting alterations in kidney and cardiovascular
structure, increased adult disease risk, and sex-specific differences in
severity

Answer

Adult
disease risk is determined almost entirely by genetic inheritance, independent
of early-life environment

Answer

Rapid
postnatal catch-up growth eliminates long-term disease risk associated with
prenatal stress

Answer

Low
birth weight leads to transient organ changes that are completely reversed by
improved postnatal nutrition
