Outcomes of pregnancy are mostly affected by work factors.

The assertion that outcomes of pregnancy are mostly affected by work factors is considered false because while work factors can have an impact, they are not the primary determinants of pregnancy outcomes. Multiple aspects influence the health of a pregnancy, including genetic factors, pre-existing health conditions, environmental exposures, lifestyle choices such as diet and exercise, and access to healthcare.

Research has shown that these personal and environmental factors often play a more significant role than occupational ones in determining the health of both the mother and the baby. Therefore, it is essential to consider the broader context of maternal and fetal health beyond just occupational influences.
