灌溉城市农业有助于在快速城市化的撒哈拉以南非洲减轻贫困和增加粮食安全，但可能无意中支持疟疾病媒。以前的研究还没有确定疟疾流行率与UA之间的可变距离效应。本研究探讨了2003年在加纳阿克拉调查的3,164名妇女自我报告的疟疾信息与家庭特征和是否接近UA地点之间的关系。疟疾自我报告与年龄、教育、总体健康状况、社会经济地位和固体废物处理方法有关。与所有居住在灌溉水源附近的妇女相比，居住在普遍获得1公里范围内的妇女自我报告的疟疾发病率明显较高，超过这一临界距离，这种关联就消失了。疟疾流行率通常在UA 1公里以内的社区升高，尽管比1公里以外的社区具有更有利的社会经济特征。应重新考虑将普遍获得服务1公里范围内的居民区作为与疟疾有关的护理的优先事项。
Irrigated urban agriculture (UA), which has helped alleviate poverty and increase food security in rapidly urbanizing sub-Saharan Africa, may inadvertently support malaria vectors. Previous studies have not identified a variable distance effect on malaria prevalence from UA. This study examines the relationships between self-reported malaria information for 3,164 women surveyed in Accra, Ghana, in 2003, and both household characteristics and proximity to sites of UA.Malaria self-reports are associated with age, education, overall health, socioeconomic status, and solid waste disposal method. The odds of self-reported malaria are significantly higher for women living within 1 km of UA compared with all women living near an irrigation source, the association disappearing beyond this critical distance. Malaria prevalence is often elevated in communities within 1 km of UA despite more favorable socio-economic characteristics than communities beyond 1 km. Neighborhoods within 1 km of UA should be reconsidered as a priority for malaria-related care.
