The causes of acute malnutrition are complex and time and geography variant and need to be better understood in order to both design more effective nutrition programs and evaluate them. The findings reported here are part of an evaluation of a 4-year multisectoral nutrition program led by Concern Worldwide in the Sila Region of eastern Chad.
To present evidence and learning about the relationships between acute malnutrition and potential drivers in Sila, Chad.
Quantitative household-level data from a clustered randomized control trial were collected in November/December 2014. The survey was complemented with water quality testing and qualitative data collected in February and March 2013 and 2014.
Households who reported not regularly cleaning the container used for transporting water for household consumption were almost twice as likely to have a malnourished child. Households living in villages with larger concentrations of cattle and having more livestock sharing the same water source as for human consumption were significantly more likely to have a malnourished child. However, cleaning the water container mediated the negative impact of living in a village with a large cattle concentration on wasting.
These results demonstrate that hygiene practices and livestock water management are correlated with acute malnutrition in Sila, Chad. These findings provide a hypothesis for a possible pathogen driving acute malnutrition rates- Cryptosporidium-as part of a complex water chain, whereby the source of infection may be mitigated by hygiene behaviors with important implications for humanitarian programs.
急性营养不良的成因复杂,因时间和地域而异,为了设计更有效的营养项目并对其进行评估,需要更好地了解这些成因。此处报告的研究结果是对由关注全球组织在乍得东部锡拉地区牵头开展的一项为期4年的多部门营养项目进行评估的一部分。
提供有关乍得锡拉地区急性营养不良与潜在驱动因素之间关系的证据和经验教训。
2014年11月/12月收集了来自整群随机对照试验的家庭层面的定量数据。该调查还辅以2013年2月和3月以及2014年收集的水质检测和定性数据。
报告不定期清洁用于运输家庭用水的容器的家庭,其孩子营养不良的可能性几乎是其他家庭的两倍。生活在牛群集中程度较高且有更多牲畜与人类共用同一水源的村庄的家庭,其孩子营养不良的可能性显著更高。然而,清洁水容器减轻了生活在牛群集中的村庄对消瘦的负面影响。
这些结果表明,卫生习惯和牲畜用水管理与乍得锡拉地区的急性营养不良相关。这些发现为一种可能导致急性营养不良率上升的病原体——隐孢子虫——作为复杂水链的一部分提供了一个假设,据此,感染源可能通过卫生行为得到缓解,这对人道主义项目具有重要意义。
