Abstract

Cross-sectional surveys were conducted to assess prevalence of night-blindness and dietary habits prior to intervention (in 1986), after 3 years of intervention (in 1989) and 3 years after the termination of active intervention (in 1992), in the northern part of Bangladesh. The prevalence of night-blindness per thousand children decreased from 1986 to 1989 (during intervention) and rose from 1989 to 1992, but remained significantly lower in 1992 than the 1986 prevalence. Household income declined from 1989 to 1992, and lower consumption of beta-carotene rich food, protein items and vitamin A capsules was registered in 1992 despite almost the same level of awareness relating to the prevention of night-blindness in the community during the period 1989-1992. The results indicate that the long-term impact of a health education programme to prevent night-blindness is uncertain. Improvement in socioeconomic conditions, in addition to relevant knowledge, is probably a precondition for maintaining a sustainable impact of health education.

摘要

在孟加拉国北部开展了横断面调查,以评估干预前(1986年)、干预3年后(1989年)以及积极干预结束3年后(1992年)夜盲症的患病率和饮食习惯。每千名儿童中夜盲症的患病率在1986年至1989年(干预期间)有所下降,在1989年至1992年有所上升,但1992年仍显著低于1986年的患病率。家庭收入从1989年至1992年有所下降,1992年富含β-胡萝卜素的食物、蛋白质类食品和维生素A胶囊的消费量较低,尽管在1989年至1992年期间社区对预防夜盲症的认知水平几乎相同。结果表明,预防夜盲症的健康教育项目的长期影响尚不确定。除了相关知识外,社会经济状况的改善可能是维持健康教育可持续影响的一个前提条件。
