Anemia is a global public health problem but the burden of anemia is disproportionately borne among children in developing countries. Anemia in early stages of life has serious consequences on the growth and development of the children. We examine the prevalence of anemia, possible association between anemia and different socio-economic, demographic, health and other factors among children with ages from 6 to 59 months from the nationally representative 2011 Bangladesh Demographic and Health Survey (BDHS).
Data on hemoglobin (Hb) concentration among the children aged 6-59 months from the most recent BDHS (2011) were used. This nationally representative survey allowed a multistage stratified cluster sampling design and provided data on a wide range of indicators such as fertility, mortality, women and child health, nutrition and other background characteristics. Anemia status was determined using hemoglobin level (<11.0 g/dl), and weighted prevalence of childhood anemia along with 95 % confidence intervals were provided. We also examined the distribution of weighted anemia prevalence across different groups and performed logistic regression to assess the association of anemia with different factors.
A total of 2171 children aged 6-59 months were identified for this analysis, with weighted prevalence of anemia being 51.9 % overall- 47.4 % in urban and 53.1 % in rural regions. Results of a multivariable logistic regression analysis showed that, children below 24 months of age (odds ratio, [OR] 3.01; 95 % confidence interval [CI] 2.38-3.81), and those from an anemic mother (OR 1.80; 95 % CI 1.49-2.18) were at higher risk of anemia. Childhood anemia was significantly associated with chronic malnutrition of child, source of drinking water, household wealth and geographical location (defined by division).
A high prevalence of anemia among 6-59 months aged children was observed in Bangladesh. Given the negative impact of anemia on the development of children in future, there is an urgent need for effective and efficient remedial public health interventions.
贫血是一个全球性的公共卫生问题，但发展中国家儿童承受着不成比例的贫血负担。生命早期的贫血会对儿童的生长发育产生严重后果。我们利用具有全国代表性的2011年孟加拉国人口与健康调查（BDHS），研究了6至59个月大儿童的贫血患病率，以及贫血与不同社会经济、人口、健康和其他因素之间可能存在的关联。
使用了最新的BDHS（2011年）中6至59个月大儿童血红蛋白（Hb）浓度的数据。这项具有全国代表性的调查采用了多阶段分层整群抽样设计，并提供了关于生育、死亡率、妇女和儿童健康、营养以及其他背景特征等广泛指标的数据。根据血红蛋白水平（<11.0 g/dl）确定贫血状况，并提供儿童贫血的加权患病率及95%置信区间。我们还研究了加权贫血患病率在不同群体中的分布情况，并进行逻辑回归分析以评估贫血与不同因素之间的关联。
本次分析共纳入2171名6至59个月大的儿童，总体贫血加权患病率为51.9%，城市地区为47.4%，农村地区为53.1%。多变量逻辑回归分析结果显示，24个月以下的儿童（比值比[OR] 3.01；95%置信区间[CI] 2.38 - 3.81）以及母亲患有贫血的儿童（OR 1.80；95% CI 1.49 - 2.18）患贫血的风险更高。儿童贫血与儿童慢性营养不良、饮用水来源、家庭财富和地理位置（按行政区划分）显著相关。
在孟加拉国观察到6至59个月大儿童贫血患病率很高。鉴于贫血对儿童未来发育的负面影响，迫切需要采取有效且高效的公共卫生干预措施进行补救。
