Nutrition-sensitive agriculture programmes have the potential to improve child nutrition outcomes, but livestock intensification may pose risks related to water, sanitation and hygiene (WASH) conditions. We assessed the impact of SELEVER, a nutrition- and gender-sensitive poultry intervention, with and without added WASH focus, on hygiene practices, morbidity and anthropometric indices of nutrition in children aged 2-4 years in Burkina Faso. A 3-year cluster randomised controlled trial was implemented in 120 villages in 60 communes (districts) supported by the SELEVER project. Communes were randomly assigned using restricted randomisation to one of three groups: (1) SELEVER intervention (n = 446 households); (2) SELEVER plus WASH intervention (n = 432 households); and (3) control without intervention (n = 899 households). The study population included women aged 15-49 years with an index child aged 2-4 years. We assessed the effects 1.5-years (WASH substudy) and 3-years (endline) post-intervention on child morbidity and child anthropometry secondary trial outcomes using mixed effects regression models. Participation in intervention activities was low in the SELEVER groups, ranging from 25% at 1.5 years and 10% at endline. At endline, households in the SELEVER groups had higher caregiver knowledge of WASH-livestock risks (∆ = 0.10, 95% confidence interval [CI] [0.04-0.16]) and were more likely to keep children separated from poultry (∆ = 0.09, 95% CI [0.03-0.15]) than in the control group. No differences were found for other hygiene practices, child morbidity symptoms or anthropometry indicators. Integrating livestock WASH interventions alongside poultry and nutrition interventions can increase knowledge of livestock-related risks and improve livestock-hygiene-related practices, yet may not be sufficient to improve the morbidity and nutritional status of young children.
营养敏感型农业计划有可能改善儿童营养状况，但畜牧业集约化可能带来与水、环境卫生和个人卫生（WASH）条件相关的风险。我们评估了 SELEVER 项目（一个注重营养和性别问题的家禽干预项目）在布基纳法索 2-4 岁儿童的卫生习惯、发病率和营养人体测量指标方面的影响，该项目同时或不额外注重 WASH。该项目在 SELEVER 项目支持下，在 60 个公社（区）的 120 个村庄开展了为期 3 年的群组随机对照试验。公社通过限制随机分配，随机分为三组：（1）SELEVER 干预组（446 户家庭）；（2）SELEVER 加 WASH 干预组（432 户家庭）；（3）对照组（无干预，899 户家庭）。研究人群包括年龄在 15-49 岁之间、有一名 2-4 岁指数儿童的妇女。我们使用混合效应回归模型评估了干预后 1.5 年（WASH 子研究）和 3 年（终线）时儿童发病率和儿童人体测量次要试验结果的影响。SELEVER 组的干预活动参与率较低，1.5 岁时为 25%，终线时为 10%。在终线时，SELEVER 组的家庭中，看护人对 WASH-牲畜风险的了解更多（∆=0.10，95%置信区间[CI] [0.04-0.16]），并且更有可能将儿童与家禽分开（∆=0.09，95% CI [0.03-0.15]），而对照组则不然。在其他卫生习惯、儿童发病症状或人体测量指标方面没有发现差异。将牲畜 WASH 干预措施与家禽和营养干预措施相结合，可以增加对牲畜相关风险的认识，并改善与牲畜卫生相关的做法，但可能不足以改善幼儿的发病率和营养状况。
