In Ethiopia, child undernutrition remains to be a major public health challenge and a contributing factor for child mortality and morbidity. To reduce the problem, it is apparent to identify determinants of child undernutrition in specific contexts to deliver appropriately, targeted, effective and sustainable interventions.
An agroecosystem linked cross-sectional survey was conducted in 3108 children aged 6-59 months. Multistage cluster sampling technique was used to select study participants. Data were collected on socio-demographic characteristics, child anthropometry and on potential immediate, underlying and basic individual and community level determinants of child undernutrition using the UNICEF conceptual framework. Analysis was done using STATA 13 after checking for basic assumptions of linear regression. Important variables were selected and individual and community level determinants of child height-for-age Z score were identified. values less than 0.05 were considered the statistical level of significance.
In the intercept only model and full models, 3.8% ( < 0.001) and 1.4% ( < 0.001) of the variability were due to cluster level variability. From individual level factors, child age in months, child sex, number of under five children, immunization status, breast feeding initiation time, mother nutritional status, diarrheal morbidity, household level water treatment and household dietary diversity were significant determinants of child height for age Z score. Also from community level determinants, agroecosystem type, liquid waste disposal practice and latrine utilization were significantly associated with child height-for-age Z score.
In this study, a statistical significant heterogeneity of child height-for-age Z score was observed among clusters even after controlling for potential confounders. Both individual and community level factors, including the agroecosystem characteristics had a significant role in determining child height-for-age Z score in the study area. In addition to the existing efforts at the individual levels to improve child nutritional status, agroecosystem and community WASH related interventions should get more attention to improve child nutritional status in the study area.
在埃塞俄比亚,儿童营养不良仍然是一项重大的公共卫生挑战,也是导致儿童死亡率和发病率的一个因素。为减少这一问题,显然需要在特定背景下确定儿童营养不良的决定因素,以便提供适当、有针对性、有效且可持续的干预措施。
对3108名6至59个月大的儿童进行了一项与农业生态系统相关的横断面调查。采用多阶段整群抽样技术选择研究参与者。使用联合国儿童基金会的概念框架收集了社会人口学特征、儿童人体测量数据以及儿童营养不良潜在的直接、根本和基本的个体及社区层面决定因素的数据。在检查线性回归的基本假设后,使用STATA 13进行分析。选择重要变量并确定儿童年龄别身高Z评分的个体和社区层面决定因素。P值小于0.05被视为具有统计学意义。
在仅含截距的模型和完整模型中,分别有3.8%(P<0.001)和1.4%(P<0.001)的变异性归因于群组层面的变异性。在个体层面因素中,月龄、儿童性别、五岁以下儿童数量、免疫状况、母乳喂养开始时间、母亲营养状况、腹泻发病率、家庭层面的水处理和家庭饮食多样性是儿童年龄别身高Z评分的显著决定因素。在社区层面决定因素中,农业生态系统类型、液体废物处理方式和厕所使用情况也与儿童年龄别身高Z评分显著相关。
在本研究中,即使在控制了潜在混杂因素之后,仍观察到各群组之间儿童年龄别身高Z评分存在统计学上的显著异质性。包括农业生态系统特征在内的个体和社区层面因素在研究区域内儿童年龄别身高Z评分的决定中都发挥了重要作用。除了现有的个体层面改善儿童营养状况的努力之外,农业生态系统和社区水、环境卫生与个人卫生相关的干预措施应得到更多关注,以改善研究区域内儿童的营养状况。
