An observed 58% increase in fetal death rates is used as an example of which category of risk factors?

• A. Environmental factors in pregnancy
• B. Genetic factors in pregnancy
• C. Nutritional factors in pregnancy
• D. Psychological factors in pregnancy

Answer: (A)

Classifying risk factors by their source helps us see what kind of influence is driving a change in outcomes. An observed 58% increase in fetal death rates points to an external influence on the developing fetus rather than something inherited. Environmental factors in pregnancy cover exposures from the surroundings—pollutants, toxins, infections, radiation, or other external conditions—that can raise risk across a population. So this pattern fits environmental factors best, because it reflects how the external environment during pregnancy can impact fetal viability. In contrast, a genetic cause would imply inherited traits, nutritional factors would tie to dietary deficiencies or imbalances, and psychological factors would relate to maternal mental health or stress.
