Abstract: | Background: A survey in Kumasi, Ghana found a marked Plasmodium falciparum prevalence
difference between two neighbouring communities (Moshie Zongo and Manhyia). The primary
objective of this follow-up study was to determine whether this parasite rate difference was
consistent over time. Secondary objectives were to compare prevalences of clinical malaria,
anaemia, intestinal parasite infections, and malnutrition between these communities; and to identify
potential risk factors for P. falciparum infection and anaemia.
Methods: A cross-sectional house-to-house survey of P. falciparum parasitaemia, clinical malaria,
anaemia, anthropometric indices, and intestinal helminths was conducted in April-May 2005. Data
collection included child and household demographics, mosquito avoidance practices, distance to
nearest health facility, child's travel history, symptoms, and anti-malarial use. Risk factors for P.
falciparum and anaemia (Hb < 11 g/dl) were identified using generalized linear mixed models.
Results: In total, 296 children were tested from 184 households. Prevalences of P. falciparum,
clinical malaria, anaemia, and stunting were significantly higher in Moshie Zongo (37.8%, 16.9%,
66.2% and 21.1%, respectively) compared to Manhyia (12.8%, 3.4%, 34.5% and 7.4%). Of 197
children tested for helminths, four were positive for Dicrocoelium dendriticum. Population
attributable risks (PAR%) of anaemia were 16.5% (P. falciparum) and 7.6% (malnutrition). Risk
factors for P. falciparum infection were older age, rural travel, and lower socioeconomic status. Risk
factors for anaemia were P. falciparum infection, Moshie Zongo residence, male sex, and younger
age.
Conclusion: Heterogeneities in malariometric indices between neighbouring Kumasi communities
are consistent over time. The low helminth prevalence, and the twofold higher PAR% of anaemia
attributable to P. falciparum infection compared to malnutrition, indicate the importance of malaria
as a cause of anaemia in this urban population. |
