Abstract
OBJECTIVE: Anemia is a major public health problem caused by multiple factors. Vitamin A (VA) depletion can affect hemoglobin concentration (Hb). This study investigated the improvement in Hb and VA status in preschool Indonesian children followingsupplementation with 210 micromol VA and deworming with 400 mg albendazole. SUBJECTS AND DESIGN:Indonesian children (n = 131) infected with Ascaris lumbricoides and/or Trichuris trichiura were enrolled. The children were grouped by length of time since receiving 210 micromol VA through the local health system. Group 1 (VA administered > or = 4 month before baseline) included 51 children with Ascaris and 29 children with Trichuris. Group 2 had received VA < or = 1 month of baseline from the local health post and included 51 children. INTERVENTION AND METHODS: Immediately following baseline Hb and VA status assessment (modified relative dose response (MRDR) test), Group 1 children were given 210 micromol VA and 400 mg albendazole. Group 2 were randomized to be dewormed either 1 week before, at the same time or 1 week after baseline MRDR and Hb measures. Follow-up assessment was 3-4 weeks after baseline. RESULTS:VA status in Group 1 significantly improved in children with either Ascaris (P < 0.0001) or Trichuris (P = 0.028). Although the prevalence of anemia declined, the improvement in Hb was not significant (P = 0.08). In Group 2, improvement in VA status from the VA delivered through the public health system was maintained for more than 1 month. Hb improved (P = 0.0037) and this improvement appeared to be associated with the length of time between deworming and follow-up assessments. CONCLUSION: Public health supplementation programs to improve VA status may also increase Hb concentrations and decrease anemia prevalence, especially when linked to deworming.
