Vitamin A deficiency in the South Pacific.

Unlabelled: Vitamin A deficiency is a major cause of morbidity, mortality and blindness among children. Although vitamin A deficiency is known to affect many children in developing countries, the magnitude of the problem in the South Pacific region is unclear.
Methods: Five cross-sectional surveys for vitamin A deficiency were conducted between 1989 and 1992 in the Republic of Kiribati, Tuvalu, the Republic of Vanuatu, Solomon Islands and the Cook Islands.
Results: In total, 10,673 children between the ages of 6 and 72 months were examined for clinical signs of vitamin A deficiency (nightblindness and xerophthalmia). The prevalence of xerophthalmia was 14.76% in the Republic of Kiribati, 1.55% in Solomon Islands, 0.59% in the Cook Islands, 0.28% in Tuvalu, and 0.11% in Vanuatu. The most common clinical findings were Bitot's spots followed by nightblindness. Xerophthalmia were more common among boys (Kiribati P < 0.001, Solomon Islands P = 0.03) and tended to occur in older preschool children (P < 0.0001).
Conclusions: These studies suggest that vitamin A deficiency is a public health problem in the Republic of Kiribati and Solomon Islands.
