Nepal has a rich history of vitamin A research and a national, biannual preschool vitamin A supplementation (VAS) programme that has sustained high coverage for 25 years despite many challenges, including conflict. Key elements of programme success have included (a) evidence of a 26-30% reduction in child mortality from two, in-country randomized trials; (b) strong political and donor support; (c) positioning local female community health volunteers as key operatives; (d) nationwide community mobilization and demand creation for the programme; and (e) gradual expansion of the programme over a period of several years, conducting and integrating delivery research, and monitoring to allow new approaches to be tested and adapted to available resources. The VAS network has served as a platform for delivering other services, including anthelmintic treatment and screening for acute malnutrition. We estimate that VAS has saved over 45,000 young lives over the past 15 years of attained national coverage. Consumption of vitamin A- and carotenoid-rich foods by children and women nationally remains low, indicating that supplementation is still needed. Current challenges and opportunities to improving vitamin A status include lower VAS coverage among younger children (infants 6-11 months of age), finding ways to increase availability and access to dietary vitamin A sources, and ensuring local programme investments given the recent decentralization of the government.
尼泊尔在维生素 A 研究方面有着丰富的历史,并且开展了一项全国性的、每半年一次的学前儿童维生素 A 补充(VAS)计划,尽管面临许多挑战,包括冲突,该计划仍持续了 25 年,保持了高覆盖率。该计划成功的关键要素包括:(a) 两项国内随机试验证明儿童死亡率降低了 26-30%;(b) 强有力的政治和捐助者支持;(c) 将当地女性社区卫生志愿者定位为主要执行者;(d) 全国范围内的社区动员和对该计划的需求创造;以及 (e) 在几年内逐步扩大计划,开展和整合交付研究,并进行监测,以便测试和调整新方法以适应现有资源。VAS 网络一直是提供其他服务的平台,包括驱虫治疗和急性营养不良筛查。我们估计,在过去 15 年实现全国覆盖的过程中,VAS 已挽救了超过 45000 名儿童的生命。全国儿童和妇女对富含维生素 A 和类胡萝卜素的食物的消费仍然很低,这表明仍需要补充维生素 A。目前改善维生素 A 状况的挑战和机遇包括:年龄较小的儿童(6-11 个月大的婴儿)的 VAS 覆盖率较低、寻找增加饮食中维生素 A 来源的供应和获取途径的方法、以及考虑到政府最近的权力下放,确保当地计划投资。
