Socio-demographic and Environmental Factors Influencing a Symptomatic Malaria and Anaemia Incidence among School Children in Fako Division, South West Cameroon

摘要

Aim: This work was aimed to assess the influence of socio-demographic and environmental factors on the incidence of asymptomatic malaria and anaemia among pupils in Fako Division, southwest Cameroon. Experimental Design: The study was a cross-sectional survey. Place and Duration of Study: The study was carried out in Fako Division, southwest Cameroon -Bolifamba, Dibanda and Mutengene from February to March, 2013. Methodology: A total of 316 pupils aged 4–15 years were studied. Data on socio-demographic and environmental factors was obtained from a semi-structured questionnaire. Blood samples were collected. Malaria parasite incidence and density were determined from Giemsa-stained thin and thick blood smears respectively. Haemoglobin (Hb) levels were determined using a haemoglobinometer. Results: The overall incidence of asymptomatic malaria was 43.4% (CI=38-48.9). Malaria incidence was significantly highest (χ2=7, P =0.03) in pupils of 6-10 years age group (49.0%, CI=42.1-59.9) when compared with their counterparts. Although not significant, malaria parasite incidence was higher in males, pupils with fever, highest in pupils of Bolifamba and poor social status than their respective counterparts. Geometric mean parasite density (GMPD) was significantly highest (Kruskal Wallis test, *χ2=6.4, P =0.04) in Dibandathan other sites. Anaemia incidence was higher among inhabitants of Dibanda (56.7%) than other sites. Anaemia incidence was statistically higher (χ2=5.6, P =0.02) in malaria positive pupils, highest in Dibanda (χ2=27.244, P 2=13.4, P =0.001) and Mutengene (F=21.2, P =0.0001) when compared with their respective counterparts. Conclusion: Sensitization on effective malaria control strategies needs to be emphasized so that a reduction in malaria burden can be achieved.
