Question

Quizplus · Accepted Answer

Smoking is the leading cause of low birth weight in developed countries. Studies have shown that smoking during pregnancy restricts blood flow to the fetus, leading to reduced oxygen and nutrient supply. This can result in a low birth weight baby, which can lead to numerous health risks both in infancy and later in life. Cocaine use and drinking alcohol during pregnancy are also known to have negative effects on fetal development and can contribute to low birth weight. Mega-dosing of vitamins is not a known cause of low birth weight.
