Which of the following is considered an environmental factor in pregnancy?

• A. Air quality
• B. Genetic makeup
• C. Maternal height
• D. Paternal age

Answer: (A)

Air quality is considered an environmental factor in pregnancy because it reflects the external exposures in the surrounding environment that can influence fetal development. Pollutants such as fine particulate matter, ozone, and nitrogen oxides can enter the mother’s bloodstream and reach the placenta, causing oxidative stress and inflammation that can affect growth and development. This exposure has been linked to outcomes like preterm birth and low birth weight, illustrating how the environment can shape pregnancy outcomes. In contrast, genetic makeup is inherited and fixed, while maternal height and paternal age are biological or demographic characteristics rather than environmental exposures.
