To investigate the prevalence of asymptomatic malaria parasitaemia and anemia in nursery and primary school children and correlate parasite density with haemoglobin levels.
Cross sectional study.
Samples were collected from children attending the Saint Theresa's bilingual school and the Government Primary school, Buea, South West Province, Cameroon.
297 nursery and primary school children two to 11 years old selected based on parental consent. MAIN OUTOME MEASURES: Relationship between asymptomatic malaria and anaemia.
The prevalence of asymptomatic malaria in children was 30.3%. Parasite prevalence and density was independent of age and sex (p > 0.05). The mean haemoglobin level for parasitaemic children was 11.9 g/dl (+/- SD1.1) compared with 12.1 g/dl (+/- 1.2) for non-parasitaemic children. The difference was not significant (t = 1.918, p > 0.05). Anaemia when present was mild. No correlation was found between malaria parasite density and haemoglobin levels (r = -0.065; p > 0.05).
Asymptomatic malaria was accompanied by low grade parasitaemia, which did not seem to have a significant effect on haemoglobin levels.
调查幼儿园及小学儿童无症状疟原虫血症和贫血的患病率，并将寄生虫密度与血红蛋白水平进行关联分析。
横断面研究。
样本采集自喀麦隆西南省布埃亚的圣特雷莎双语学校和政府小学的儿童。
297名2至11岁的幼儿园及小学儿童，经家长同意入选。主要观察指标：无症状疟疾与贫血之间的关系。
儿童无症状疟疾的患病率为30.3%。寄生虫患病率和密度与年龄及性别无关（p>0.05）。疟原虫血症儿童的平均血红蛋白水平为11.9g/dl（±标准差1.1），而非疟原虫血症儿童为12.1g/dl（±1.2）。差异无统计学意义（t=1.918，p>0.05）。贫血若存在则为轻度。未发现疟原虫密度与血红蛋白水平之间存在相关性（r=-0.065；p>0.05）。
无症状疟疾伴有低度疟原虫血症，这似乎对血红蛋白水平无显著影响。
