The prevalence of vitamin A deficiency in 1994 on an atoll of the Marshall Islands and its relationship to locally grown food.

In an area of the world not previously studied for the presence of nutritional deficiencies, this study conducted in 1994, examined the prevalence of Vitamin A deficiency on a representative atoll of the Marshall Islands. All children ages three through ten living on Mili atoll were surveyed. The study was conducted house-to-house with all 38 subjects on the atoll voluntarily enrolling in the study. Vitamin A status was assessed by conjunctival impression cytology with transfer ([CT), clinical ophthalmic signs, and nutritional survey in all children ages three through ten living on Mili atoll, Republic of the Marshall Islands. Forty-seven percent had xerophthannia (5% with XN, 39% with XN + XIA, and 3% with XN + XIB). More than three-quarters (78%) were ICT abnormal, indicating 31% of the population had mild sub-clinical vitamin A deficiency. Eighty-six percent of the children had not received the U.S. recommended daily allowance of vitamin A in the previous week. Oiven the World Health Organization's published guidelines that anything greater than a 1% prevalence, Vitamin A deficiency on Mili atoll may be classified as a significant public health problem.
