Anemia during childhood impairs physical growth, cognitive development and school performance. Identifying the causes of anemia in specific contexts can help efforts to prevent negative consequences of anemia among children. The objective of this study was to assess prevalence and identify correlates of anemia among school children in Eastern Ethiopia.
A cross sectional study was conducted from January 2012 to February 2012 in Kersa, Eastern Ethiopia. The study included randomly selected primary school students. Hemoglobin concentration was measured using a Hemocue haemoglobinometer. A child was identified as anemic if the hemoglobin concentration was <11.5 g/dl for children (5-11 yrs) and < 12 g/dl for child older than 12 years age. Poisson regression model with robust variance was used to calculate prevalence ratios.
The overall prevalence of anemia was 27.1% (95% CI: 24.98, 29.14): 13.8% had mild, 10.8% moderate, and 2.3% severe anemia. Children with in the age group of 5-9 years (APR, 1.083; 95% CI, 1.044-1.124) were at higher risk for anemia. Paternal education (Illiterate, 1.109; 1.044-1.178) was positively associated with anemia. Children who had irregular legume consumption (APR, 1.069; 95% CI, 1.022-1.118) were at higher risk for anemia.
About a quarter of school children suffer from anemia and their educational potential is likely to be affected especially for those with moderate and severe anemia. Child age, irregular legume consumption, and low paternal schooling were associated with anemia. Intervention programmes aimed to reduce anemia among school children are crucial to ensure proper growth and development of children.
儿童期贫血会损害身体发育、认知发展和学业表现。在特定环境中确定贫血原因有助于预防儿童贫血带来的负面后果。本研究的目的是评估埃塞俄比亚东部学龄儿童贫血的患病率并确定其相关因素。
2012年1月至2012年2月在埃塞俄比亚东部的克尔萨进行了一项横断面研究。该研究纳入了随机选取的小学生。使用血红蛋白仪测量血红蛋白浓度。对于5至11岁的儿童,血红蛋白浓度<11.5 g/dl,12岁及以上的儿童血红蛋白浓度<12 g/dl,则被认定为贫血。采用具有稳健方差的泊松回归模型计算患病率比值。
贫血的总体患病率为27.1%(95%置信区间:24.98, 29.14):13.8%为轻度贫血,10.8%为中度贫血,2.3%为重度贫血。5至9岁年龄组的儿童(患病率比值,1.083;95%置信区间,1.044 - 1.124)患贫血的风险更高。父亲的教育程度(文盲,1.109;1.044 - 1.178)与贫血呈正相关。豆类食用不规律的儿童(患病率比值,1.069;95%置信区间,1.022 - 1.118)患贫血的风险更高。
约四分之一的学龄儿童患有贫血,他们的教育潜力可能会受到影响,尤其是那些患有中度和重度贫血的儿童。儿童年龄、豆类食用不规律和父亲受教育程度低与贫血有关。旨在减少学龄儿童贫血的干预项目对于确保儿童的正常生长发育至关重要。
