Stunting is the natural condition of human height

Abstract

Objectives: Human body height differs within a wide range and has conventionally been associated with genetic, nutritional, and environmental conditions. In this study, we try to broaden this perspective and add the evolutionary aspect of height differences.

Sample and method: We revisited height from archeological data (10 000-1000 BC), and historical growth studies (1877-1913). We analyzed height, weight, and skinfold thickness of 1666 Indonesian schoolchildren from six representative rural and urban elementary schools in Bali and West Timor with a stunting prevalence of up to 50%.

Results: Stature in the Holocene prehistory of the Near East and Europe varied with maxima for women usually ranging below 160 cm, and maxima for men between 165 and 170 cm. Stature never rose above 170 cm. European and white US-American schoolchildren of the 19th and 20th century were generally short with average height ranging between -1.5 and -2.2 hSDS, yet in the absence of any evidence of chronic or recurrent undernutrition or frequent illness, poverty, or disadvantageous living conditions. The same is found in contemporary Indonesian schoolchildren.

Conclusion: Stunting is frequently observed not only in the poor, but also in affluent and well-nourished social strata last 10 000 years. Only in very recent history, and only in a few democratic, modern societies, stature has increased beyond the long-lasting historic height average. Viewed from an evolutionary perspective, and considering adaptive plasticity of and community effects on growth, competitive growth and strategic growth adjustments, stunting appears to be the natural condition of human height.
