Mixed longitudinal data on growth and maturation have been obtained from about 200 girls in one county in Iowa. Heights, weights and serum alkaline phosphatase activity have been presented by age. In general, these girls were about the same average height as Iowa girls measured in the 1930’s but their weight was greater. Compared with populations of girls on the east and west coasts of the United States, girls from Iowa were apt to be heavier for their height. Serum alkaline phosphatase activity reflected rate of increases in height; those girls who were “advanced” in skeletal age over their chronological age grew faster at an earlier age, and their serum alkaline phosphatase decreased earlier than their age-mates whose skeletal age was “normal.” |
