据报道，南非有20%-75%的儿童患有贫血症。这一范围表明了地理、健康和社会经济地位对特定社区内观察到的贫血患病率的影响。我们的目标是调查在林波波省Thoyandou的一家社区卫生中心接受健康儿童检查的5岁以下儿童的贫血患病率。2007年6月和7月进行了一项横断面观测研究。照顾者参加了一次简短的采访，收集了人口统计、健康和营养信息。从每个孩子身上采集一份血液样本，并使用护理点血红蛋白测试系统评估血红蛋白水平。贫血被定义为血红蛋白值低于年龄-海拔调整正常值2个标准差。四分之三(39/52-75%)的儿童患有贫血。女孩贫血的可能性明显高于男孩(分别为20/20vs19/32；p=0.001)。与同龄人相比，贫血儿童体重不足的可能性显著降低(分别为32/38比5/12；p=0.007)。贫血与感染幽门螺杆菌(p=0.729)、肠道蠕虫(p=1.000)或食物不安全(p=0.515)没有显著关联。我们发现，在林波波省Thoyandou，临床状况良好的5岁儿童中，贫血的患病率很高。贫血率高于之前在南非类似环境下进行的研究。今后的工作应侧重于病因和干预措施。
Anaemia has been reported to affect 20 – 75% of children in South Africa. The range suggests the effects that geography, health, and socio-economic status can have on the observed prevalence of anaemia within a specific community. Our objective was to investigate the prevalence of anaemia in children aged under 5 presenting for well-child examinations at a community health centre in Thohoyandou, Limpopo Province. A cross-sectional observational study was carried out in June and July 2007. Caregivers participated in a brief interview where demographic, health and nutritional information was collected. A blood sample was collected from each child, and haemoglobin levels were assessed with a point-of-care haemoglobin testing system. Anaemia was defined as having a haemoglobin value <2 standard deviations below age-altitude adjusted normal values. Three-quarters (39/52 – 75%) of children were anaemic. Girls were significantly more likely to be anaemic than boys (20/20 v. 19/32 respectively; p=0.001). Anaemic children were significantly less likely to be underweight compared with their peers (32/38 v. 5/12 respectively; p=0.007). There was no significant association between anaemia and infection with Helicobacter pylori (p=0.729), intestinal helminths (p=1.000) or food insecurity (p=0.515). We found a striking prevalence of anaemia among clinically well children <5 years old in Thohoyandou, Limpopo Province. The rates of anaemia were higher than those found in previous studies conducted in similar settings in South Africa. Future work should focus on aetiologies and interventions.
