| Résumé : | [BDSP. Notice produite par INIST R0xcxwKs. Diffusion soumise à autorisation]. In Bangladesh, a national nutritional surveillance system was initiated in 1990 to monitor 1) the occurrence of vitamin A deficiency by history of night blindness and 2) the routine coverage of national twice-yearly prophylactic vitamin A capsule (VAC) distribution. This study comprised data collected from June 1990 to August 1994. The VAC distribution had a mean coverage rate of 48.7% (95% confidence interval (Cl) 48.4-49.0) in the rural areas ; the coverage rate in the urban slums was 93.7% (95% Cl 93.4-94.0). In the rural areas, the mean prevalence of night blindness was 0.86% (95% Cl 0.81-0.91) and the bimonthly prevalence of night blindness ranged from 0.50% (95% Cl 0.32-0.77) to 1.48% (95% Cl 1.19-1.85), while in the urban slums the mean prevalence was 0.22% (95% Cl 0.18-0.28) and the bimonthly prevalence ranged from zero to 0.62% (95% Cl 0.27-1.37). Although the prevalence of vitamin A deficiency in Bangladesh has been considerably lower in the 1990s than it was in the 1980s, it is still prevalent at all socioeconomic levels. Supplementation with high-dose VACs is an effective strategy for reducing night blindness, but the efficiency of the program will improve when coverage in the rural areas increases. |
