目的：研究在孟加拉国农村地区，在国家维生素A补充项目的存在下，宅基地粮食生产与学龄前儿童夜盲症之间的关系。设计：一项横断面研究。设置：孟加拉国营养监测项目2001- 2005年评估的孟加拉国6个农村地区的基于人口的样本。结果：过去6个月内服用和未服用维生素A胶囊的儿童夜盲症患病率分别为0.07%和0.13%。鉴于维生素A补充剂对夜盲症的已知影响，该分析按儿童在过去6个月内接受维生素A胶囊进行分层。在过去6个月未接受维生素A胶囊的儿童中，缺乏家庭花园与夜盲症的几率增加相关（OR = 3.16，95%CI 1.76，5.68; P = 0.0001）。在过去6个月接受维生素A胶囊的儿童中，缺乏家庭花园与夜盲症无关（OR = 1.28，95%CI 0.71，2.31; P = 0.4）。结论：宅基地食品生产对孟加拉国农村错过维生素A补充剂的学龄前儿童夜盲症具有保护作用。
Objective: To examine the relationship between homestead food production and night blindness among pre-school children in rural Bangladesh in the presence of a national vitamin A supplementation programme.Design: A cross-sectional study.Setting: A population-based sample of six rural divisions of Bangladesh assessed in the Bangladesh Nutrition Surveillance Project 2001-2005.Subjects: A total of 158 898 children aged 12-59 months.Results: The prevalence rates of night blindness in children among those who did and did not receive vitamin A capsules in the last 6 months were 0.07% and 0.13 %, respectively. Given the known effect of vitamin A supplementation on night blindness, the analysis was stratified by children's receipt of vitamin A capsules in the last 6 months. Among children who did not receive vitamin A capsules in the last 6 months, the lack of a home garden was associated with increased odds of night blindness (OR = 3.16, 95% CI 1.76, 5.68; P = 0.0001). Among children who received vitamin A capsules in the last 6 months, the lack of a home garden was not associated with night blindness (OR = 1.28, 95% CI 0.71, 2.31; P = 0.4).Conclusions: Homestead food production confers a protective effect against night blindness among pre-school children who missed vitamin A supplementation in rural Bangladesh.
