Nutritional status and endemic goitre.

Y Ingenbleek, B Luypaert, P De Nayer

    Lancet (London, England)
    |February 23, 1980
    PubMed
    Summary

    Protein malnutrition may explain reduced thyroid function and vitamin A levels in Senegalese goiter patients. In these patients, serum thyroxine is a better indicator of thyroid status than triiodothyronine.

    Area of Science:

    • Endocrinology
    • Nutritional Science
    • Public Health

    Background:

    • Goiter is prevalent in endemic areas of Senegal.
    • Thyroid function and vitamin A status are crucial for overall health.
    • Protein malnutrition is a common issue in developing regions.

    Purpose of the Study:

    • To compare thyroid function and serum-retinol levels in goitrous patients versus controls.
    • To investigate the impact of protein malnutrition on thyroid hormone regulation.
    • To determine the best indicator of thyroid function in malnourished goitrous individuals.

    Main Methods:

    • Comparative analysis of biochemical indices.
    • Measurement of thyroid-binding proteins and serum-retinol.
    • Assessment of thyrotropic hormone feedback regulation.

    Main Results:

    • Goitrous patients exhibited reduced thyroid-binding proteins and serum-retinol.
    • These findings suggest protein malnutrition as a contributing factor.
    • Thyroid hormone feedback regulation was primarily influenced by thyroxine.

    Conclusions:

    • Protein malnutrition significantly affects thyroid function and vitamin A levels in goitrous populations.
    • Serum thyroxine is a more reliable indicator of thyroid function than triiodothyronine in malnourished goitrous patients.
    • Public health strategies should address both iodine deficiency and protein-energy malnutrition in endemic goiter regions.
