Nutritional and household risk factors for xerophthalmia in Aceh, Indonesia: a case-control study. The Aceh Study Group.

Risk factors for xerophthalmia were assessed in 466 subjects [38% with night blindness (XN), 60% with Bitot's spots (X1B), 2% with corneal xerophthalmia (X2 or X3)] under age 6 y and their village-age-sex-matched control subjects during a community trial. Socioeconomic status and hygiene standards were lowest for households of xerophthalmic children and highest for nonstudy households in the trial population, with values for control households lying in between (P less than 0.001 by linear trend).

Determinants of community-based coverage: periodic vitamin A supplementation. Aceh Study Group.

Factors related to preschool child receipt of vitamin A during the first year of a semi-annual vitamin A capsule delivery program were investigated in 229 villages in Aceh, Indonesia. Coverage was higher in villages which were more rural and less economically developed. Highest performance was achieved by village distributors who represented the local status quo in this rural area (farmers, or non-farmers with minimum education) rather than more upwardly mobile, highly educated residents.

Interactions of community nutritional status and xerophthalmia in Indonesia.

In order to determine which community level factors best explain the variation in the prevalence of xerophthalmia, an analysis was done on risk factors of xerophthalmia from the Indonesian Nutritional Blindness Study (1976 to 1979). Because of the common belief that xerophthalmia is closely linked to malnutrition, and the fact that within the study itself, it was demonstrated that children with xerophthalmia had a much higher prevalence of malnutrition than normal children, the relationship between the prevalence of malnutrition and the prevalence of xerophthalmia was explored. Using two different statistical approaches the prevalence of malnutrition within a community could not be demonstrated to be a good predictor of the prevalence of xerophthalmia within that community.
