Lung function in highlander Bods of Ladakh.

S L Malik, I P Singh

    American Journal of Physical Anthropology
    |September 1, 1979
    PubMed
    Summary

    Highland Bods in Ladakh exhibit enhanced respiratory function and larger chest dimensions, similar to Peruvian populations. These adaptations are likely due to low oxygen pressure, though genetics and activity levels may also contribute.

    Area of Science:

    • Physiological Anthropology
    • Environmental Adaptation
    • Human Biology

    Background:

    • Populations residing at high altitudes often exhibit physiological adaptations to cope with reduced oxygen availability.
    • Previous studies have noted similarities between highland populations in different geographical regions.

    Purpose of the Study:

    • To investigate the biological responses of adolescent male Bods in Leh, Ladakh, to their high-altitude environment.
    • To compare the physiological characteristics of highland Bods with other populations.

    Main Methods:

    • Cross-sectional study design.
    • Inclusion of 221 male Bods aged 11 to 19 years from Leh, Ladakh.
    • Measurement of respiratory function (forced vital capacity) and chest dimensions.

    Main Results:

    • Bods demonstrated higher forced vital capacity compared to lowland populations.
    • A significant association was observed between chest measurements and respiratory function.
    • Chest dimensions were found to be increased in this highland population.
    • Findings were comparable to those reported for highland Peruvians.

    Conclusions:

    • The observed physiological differences in Bods may be partly attributed to the low oxygen pressure at high altitudes.
    • Genetic factors and varying activity levels are also considered potential contributors to these adaptations.
    • Further research is warranted to fully elucidate the interplay of environmental, genetic, and behavioral factors.
