目的：确定撒哈拉以南非洲地区育龄妇女（WCBA）和学龄前儿童血红蛋白浓度与牲畜拥有量之间的关系。对公开可用的横断面数据进行前瞻性分析，使用线性和逻辑回归控制潜在的混杂因素。SSA的28个国家。162,305名WCBA和118,607名6-59个月的儿童。超过一半的WCBA（62.5%）和儿童（58%）属于拥有牲畜的家庭。WCBA和儿童的平均海拔调整血红蛋白浓度分别为12.23 g/dL和10.24 g/dL。在调整后的模型中，拥有的牲畜数量越多，儿童血红蛋白浓度越低，而与WCBA无关。儿童的关联程度很小，每增加一个牲畜单位，血红蛋白浓度就会降低0.001 g/dL。牛、母牛和公牛、绵羊和山羊的数量越多，两组的血红蛋白浓度越低。拥有某些种类牲畜的数量与儿童对相关食物的消费有关。动物源性食品的消费与血红蛋白浓度之间没有关联，牲畜饲养与儿童腹泻或发烧之间也没有关联。SSA地区牲畜拥有量与儿童血红蛋白浓度呈净负相关，与WCBA无相关。研究结果突出表明，有必要开展研究，以澄清牲畜所有权与营养状况之间的联系机制，并确定利用牲畜所有权改善撒哈拉以南非洲妇女和儿童健康的切入点。
To determine the association between livestock ownership and hemoglobin concentration of women of child-bearing age (WCBA) and preschool-aged children in Sub-Saharan Africa (SSA). A prospective analysis of publicly-available cross-sectional data, using linear and logistic regressions controlling for potential confounders. Twenty-eight countries in SSA. 162,305 WCBA and 118,607 children aged 6–59 months. More than half of WCBA (62.5%) and children (58%) belonged to households that owned livestock. The average altitude-adjusted blood hemoglobin concentration for WCBA and children was 12.23 g/dL and 10.24 g/dL, respectively. In adjusted models, higher number of livestock owned was associated with lower hemoglobin concentration for children but not for WCBA. The magnitude of the association for children was small, with one additional unit of livestock owned reducing hemoglobin concentration by 0.001 g/dL. Higher numbers of cattle, cows and bulls, sheep, and goats were associated with lower hemoglobin concentration for both groups. The number of certain categories of livestock owned was associated with the consumption of relevant foods by children. There was no association between the consumption of animal-source foods and hemoglobin concentration or between livestock ownership and diarrheal diseases or fever among children. Livestock ownership in SSA had a net negative association with the hemoglobin concentration of children and no association with that of WCBA. The results highlight the need for research aimed at clarifying the mechanisms linking livestock ownership and nutritional status, and identifying entry points for leveraging livestock ownership to improve the health of women and children in SSA.
