Anemia is a leading contributor to child morbidity and mortality in Sub-Saharan Africa. In Uganda, more than half of the children under 5 years are affected by anemia. Understanding context-specific determinants remains critical for targeted interventions. This study examined the community prevalence and factors associated with anemia among children aged 6-59 months in the Busoga Region of Uganda.
This community-based cross-sectional study included 439 caretaker-child dyads with children aged 6-59 months. Multistage random sampling was used to select households, and one eligible child was recruited. A pre-tested electronic face-to-face interviewer-administered questionnaire was used to collect the data. Capillary blood samples from each child were obtained through a finger or heel prick, and hemoglobin concentration was measured using standardized HemoCues. The United Nations Children's Fund (UNICEF) cut-offs were used to determine anemia status among children after adjusting for altitude. Bivariate and multivariable Modified Poisson Regression tested the association between key demographic variables and child anemia using unadjusted and adjusted prevalence ratios (APRs). Variables with ≤ 0.2 at bivariate analysis were included in the multivariate regression models, using a backward stepwise method. Covariates with < 0.05 were considered risk factors for anemia.
The mean age of the caretakers was 31 ± 11 years, with only 19 (4.3%) males. More than half (52.0%) of the children were male. Among the sampled children, 229 (52.2%) had a history of malaria, 212 (48.3%) were not dewormed, 296 (67.4%) were anemic, 22 (5.0%) had severe anemia, and 161 (36.7%) had moderate anemia. Children had a higher risk of anemia if they had a history of malaria (APR = 1.2 [1.1-1.4], = 0.023), and had a caretaker aged between 45 and 59 years (APR = 1.5 [1.1-2.1], = 0.025). Conversely, children aged 36-47 and 48-59 months (APR = 0.6 [0.5-0.8], = < 0.001, and APR = 0.6 [0.5-0.8], = 0.006, respectively) were less likely to be anemic.
Anemia among children is a severe public health problem in the Busoga Region. It was associated with having a history of malaria, child age, and caretaker age. Interventions such as the distribution of long-lasting insecticidal nets, malaria vaccination, chemoprophylaxis, and sensitization of caregivers on adequate child feeding practices could reduce the anemia burden in the region.
贫血是撒哈拉以南非洲儿童发病和死亡的主要原因。在乌干达,超过半数的5岁以下儿童受贫血影响。了解特定背景下的决定因素对于有针对性的干预措施仍然至关重要。本研究调查了乌干达布索加地区6至59个月儿童的社区贫血患病率及相关因素。
这项基于社区的横断面研究纳入了439对照顾者与6至59个月儿童的二元组。采用多阶段随机抽样选择家庭,并招募一名符合条件的儿童。使用经过预测试的电子面对面访谈式问卷收集数据。通过手指或足跟针刺采集每个儿童的毛细血管血样,并使用标准化的血红蛋白仪测量血红蛋白浓度。在调整海拔高度后,采用联合国儿童基金会(UNICEF)的临界值来确定儿童的贫血状况。二元和多变量修正泊松回归使用未调整和调整后的患病率比(APR)来检验关键人口统计学变量与儿童贫血之间的关联。在二元分析中比值≤0.2的变量采用向后逐步法纳入多变量回归模型。P<0.05的协变量被视为贫血的危险因素。
照顾者的平均年龄为31±11岁,男性仅19人(4.3%)。超过半数(52.0%)的儿童为男性。在抽样儿童中,229人(52.2%)有疟疾病史,212人(48.3%)未驱虫,296人(67.4%)贫血,22人(5.0%)重度贫血,161人(36.7%)中度贫血。有疟疾病史的儿童贫血风险更高(APR = 1.2 [1.1 - 1.4],P = 0.023),照顾者年龄在45至59岁之间的儿童贫血风险也更高(APR = 1.5 [1.1 - 2.1],P = 0.025)。相反,36至47个月和48至59个月的儿童贫血可能性较小(APR分别为0.6 [0.5 - 0.8],P<0.001和APR = 0.6 [0.5 - 0.8],P = 0.006)。
儿童贫血是布索加地区严重的公共卫生问题。它与疟疾病史、儿童年龄和照顾者年龄有关。分发长效驱虫蚊帐、疟疾疫苗接种、化学预防以及对照顾者进行适当儿童喂养方法的宣传等干预措施可以减轻该地区的贫血负担。
