Quizplus · Accepted Answer

Maternal cigarette smoking is the main cause of low birth weight in developed countries. Smoking during pregnancy can reduce the amount of oxygen and nutrients that reach the fetus, leading to slower fetal growth and lower birth weight. Other factors such as maternal drug abuse and anemia can also contribute to low birth weight, but they are not as prevalent in developed countries as cigarette smoking. Maternal malnourishment is more common in developing countries.
