Which is true of populations living at high altitudes compared to those living at sea level?

Low birth weight are more frequent at high altitude

Explanation:

From research that has been conducted overtime it has been established that birth weight declines with an increasing altitude. High altitude causes a reduction in birth weight compared to those who live at sea level. Babies born on high altitude could be about some ounces lighter than those that are born at sea level. On the average as altitude rises by about 3,300 feet, fetal weight reduces by about 3.5 ounces.
