Higher food prices increase the risk of vitamin A deficiency among preschool children in poor families, because a larger part of the household food budget is spent on grain foods and less on vitamin A-rich foods. Vitamin A supplementation is an important source of vitamin A for children. Our objective was to characterize coverage of the India national vitamin A program for preschool children and identify risk factors for not receiving vitamin A. Anthropometric and demographic data were examined in 23,008 children aged 12-59 mo in the India National Family Health Survey, 2005-2006. Within the last 6 mo, 20.2% of children received vitamin A supplementation. The prevalence of stunting, severe stunting, underweight, and severe underweight was higher among children who did not receive vitamin A compared with those who received vitamin A (P < 0.0001). In families with a child who did and did not receive vitamin A, respectively, the proportion with a history of under-5 child mortality was 8.4 vs. 11.4% (P < 0.0001). By state, vitamin A program coverage was inversely proportional to the under-5 child mortality rate (r = -0.51; P = 0.004). Maternal education of > or =10 y [odds ratio (OR) 2.22; 95% CI 1.69-2.91], 7-9 y (OR 1.99; 95% CI 1.57-2.53), or 1-6 y (OR 1.65; 95% CI 1.28-2.13) compared with no education was an important factor related to receipt of vitamin A. Poor coverage of the vitamin A supplementation program in India has serious implications in the face of rising food prices. Expanded coverage of the vitamin A program in India will help protect children from morbidity, mortality, and blindness.
高食品价格增加了贫困家庭学龄前儿童维生素 A 缺乏的风险,因为家庭食品预算的更大一部分用于谷物食品,而用于富含维生素 A 的食品的比例较小。维生素 A 补充剂是儿童维生素 A 的重要来源。我们的目的是描述印度国家学龄前儿童维生素 A 规划的覆盖情况,并确定未接受维生素 A 补充的危险因素。在 2005-2006 年印度国家家庭健康调查中,对 23008 名 12-59 月龄儿童的人体测量和人口统计学数据进行了分析。在过去 6 个月内,20.2%的儿童接受了维生素 A 补充。与接受维生素 A 的儿童相比,未接受维生素 A 的儿童中发育迟缓、严重发育迟缓、体重不足和严重体重不足的患病率更高(P<0.0001)。在有和没有儿童接受维生素 A 的家庭中,5 岁以下儿童死亡率的历史分别为 8.4%和 11.4%(P<0.0001)。按邦划分,维生素 A 规划的覆盖率与 5 岁以下儿童死亡率呈反比(r=-0.51;P=0.004)。母亲接受的教育程度≥10 年(比值比 2.22;95%置信区间 1.69-2.91)、7-9 年(比值比 1.99;95%置信区间 1.57-2.53)或 1-6 年(比值比 1.65;95%置信区间 1.28-2.13)与未接受教育相比,是接受维生素 A 的重要因素。印度维生素 A 补充规划的覆盖率低,在食品价格上涨的情况下后果严重。扩大印度的维生素 A 规划的覆盖范围将有助于保护儿童免受发病、死亡和失明的影响。
