Malnutrition is responsible globally for 60% of deaths among children under 5 years and is often attributed to suboptimal feeding practices. In response, the World Health Organization recommends exclusive breast-feeding for the first 6 months of life. The objective of this study was to determine if an association exists between the early introduction of water and complementary foods (CFs) and the nutritional status of children in northern Senegal.
DESIGN/SETTING/SUBJECTS: A cross-sectional study of 374 children in the Podor Health District between the ages of 6 and 23 months was conducted. Knowledge and behaviours of mothers regarding introduction of water and CFs were assessed via individual interviews.
Water was introduced to about 85% of the children in the first 3 months of life and 62% were fed CFs before 6 months. Overall, 16% had clinically significant wasting (weight-for-length Z-score (WHZ) less than - 2) and 20% had stunting (height-for-age Z-score (HAZ) less than - 2). There was no significant association between wasting or stunting and introduction of water before 3 months (WHZ: odds ratio = 0.99, 95% confidence interval 0.46-2.14, P = 0.97; HAZ: 0.68, 0.34-1.36, P = 0.3) or introduction of CFs before 6 months (WHZ: 0.81, 0.46-1.42, P = 0.5; HAZ: 0.79, 0.46-1.35, P = 0.4). A significant association was found between wasting and male sex, age, living in Guede community, drinking river/pond water and large family size, while stunting was associated with age and drinking tap water.
The results of the present study suggest that early introduction of water and CFs is frequent and is not associated with increased risk for malnutrition among children from this region of northern Senegal, but the possibility of reverse causality cannot be excluded.
全球范围内,营养不良导致5岁以下儿童60%的死亡,这通常归因于喂养方式不当。对此,世界卫生组织建议在婴儿出生后的前6个月进行纯母乳喂养。本研究的目的是确定在塞内加尔北部,过早引入水和辅食与儿童营养状况之间是否存在关联。
设计/地点/研究对象:对波多尔健康区374名年龄在6至23个月的儿童进行了横断面研究。通过个人访谈评估母亲们在引入水和辅食方面的知识与行为。
约85%的儿童在出生后的前3个月就开始摄入水,62%的儿童在6个月前就开始食用辅食。总体而言,16%的儿童有临床上显著的消瘦(身长别体重Z评分(WHZ)低于 -2),20%的儿童有发育迟缓(年龄别身高Z评分(HAZ)低于 -2)。在3个月前引入水与消瘦或发育迟缓之间无显著关联(WHZ:比值比 = 0.99,95%置信区间0.46 - 2.14,P = 0.97;HAZ:0.68,0.34 - 1.36,P = 0.3),在6个月前引入辅食与消瘦或发育迟缓之间也无显著关联(WHZ:0.81,0.46 - 1.42,P = 0.5;HAZ:0.79,0.46 - 1.35,P = 0.4)。发现消瘦与男性、年龄、居住在盖德社区、饮用河水/池塘水以及家庭规模大有关,而发育迟缓与年龄和饮用自来水有关。
本研究结果表明,在塞内加尔北部该地区,过早引入水和辅食的情况很常见,且与儿童营养不良风险增加无关,但不能排除反向因果关系的可能性。
