  • Title: Age-specific variation in the secular trend for stature: a comparison of samples from industrialized and nonindustrialized regions.
    Author: McCullough JM, McCullough CS.
    Journal: Am J Phys Anthropol; 1984 Oct; 65(2):169-80. PubMed ID: 6507607.
    Abstract:
    Age-specific secular trend patterns for children in industrialized world regions have a regular pattern, beginning low at age 6 and increasing to a maximum at age 10 to 14, then declining. While magnitude differs, the patterns are ordinarily parallel, especially in the female samples. However, age-specific secular trend values for children from developing regions, or from areas of industrialized countries not benefitting substantially from development, are irregular in pattern and magnitude. Consequently, it is difficult to predict age at maximal secular change. We suggest that fluctuating environmental circumstances in these developing countries influence growth and, hence, the pattern of secular trend. As more stable environmental conditions relating to growth are present in the industrialized countries, this leads to more stable patterns of growth and age-specific patterns of secular change.
