Abstract
Growth and development are clearly affected by high-altitude exposure to hypoxia, nutritional stress, cold or a combination
of these factors. Very little research has been conducted on the growth and nutritional status of children living on
the Tibetan Plateau. The present study evaluated the environmental impact on human growth by analyzing anthropometric
characteristics of Tibetan children aged 8–14, born and raised above 4000 m altitude on the Himalayan massif
in the prefecture of Shegar in Tibet Autonomous Region. Data on anthropometric traits, never measured in this population,
were collected and the nutritional status was assessed. A reference data set is provided for this population. There
was no evidence of wasting but stunting was detected (28.3%). Children permanently exposed to the high-altitude environment
above 4000 m present a phenotypic form of adaptation and a moderate reduction in linear growth. However, it is
also necessary to consider the effects of socioeconomic deprivation.
