A physiological adaptation to undernutrition.
A total of 432 children under the age of 10 years were measured for height and weight, and the morbidity and mortality indices were studied in six counties of the maize region of the state of Yucatán, Mexico. Undernutrition, because of its relationship to morbidity and mortality, was considered an important selection factor operating between the ages of 6 and 24 months. It was also observed that short stature was an adaptive response to the first years of undernutrition, that allowed children to maintain an adequate body weight under conditions of nutritional stress during the first 10 years of life.
