“…The reported use of mosquito nets by adults was below 42% in Bioko Island in 1996 and 2001, lower than the reported frequency in neighbouring countries [23], but consistent with the 41% reported in 2004 [37]. Inaccessibility to cost-free bed nets was reportedly the main reason given for not using them in our surveys.…”

“…20 records met our inclusion criteria (table), [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] and of these 15 contained the necessary data for inclusion in the quantitative analysis (meta-analysis). Five records were excluded from the quantitative analysis either because Bayesian credible intervals were reported (n=2) or because ORs could not be calculated from the available data (n=3)[A: sentence correct as edited?].…”

Official URL: http://dx.doi.org/10.1016/S0140-6736(13)60851-X More details/abstract: Background: Future progress in tacking malaria mortality will probably be hampered by the development of resistance to drugs and insecticides and by the contraction of aid budgets. Historically, control was often achieved without malaria specific interventions. Our aim was to assess whether socioeconomic development can contribute to malaria control. Methods: We did a systematic review and meta-analysis to assess whether the risk of malaria in children aged 0-15 years is associated with socioeconomic status. We searched Medline, Web of Science, Embase, the Cochrane Database of Systematic Reviews, the Campbell Library, the Centre for Reviews and Dissemination, Health Systems Evidence, and the Evidence for Policy and Practice Information and Co-ordinating Centre evidence library for studies published in English between Jan 1, 1980, and July 12, 2011, that measured socioeconomic status and parasitologically confirmed malaria or clinical malaria in children. Unadjusted and adjusted effect estimates were combined in fixed effects and random-effects meta-analyses, with a subgroup analysis for different measures of socioeconomic status. We used funnel plots and Egger's linear regression to test for publication bias. Findings: Of 4696 studies reviewed, 20 met the criteria for inclusion in the qualitative analysis, and 15 of these reported the necessary data for inclusion in the meta-analysis. The odds of malaria infection were higher in the poorest children than in the least poor children (unadjusted odds ratio [OR] 1•66, 95% CI 1•35-2•05, p<0•001, I²=68%; adjusted OR 2•06, 1•42-2•97, p<0•001, I²=63%), an effect that was consistent across subgroups. Interpretation: Although we would not recommend discontinuation of existing malaria control efforts, we believe that increased investment in interventions to support socioeconomic development is warranted, since such interventions could prove highly effective and sustainable against malaria in the long term.

“…Some studies have shown a positive association while others did not. For example, in a study conducted in Equatorial Guinean children, stunting was positively related to malaria infection, while no significant association was found with wasting and underweight (Custodio et al, 2009). Additionally, in another study conducted in Ghanaian children, Crookston et al (2010), found no significant association between chronic undernutrition and asymptomatic malaria detected by polymerase chain reaction (PCR).…”

Malaria and soil-transmitted helminths are common parasitic diseases found in school children in subSaharan Africa. We determined the prevalence and intensities of these infections in apparently healthy schoolchildren living in Mfou health district, where malaria and intestinal infections are among the first causes of morbidity. In a cross-sectional study involving 503 schoolchildren, anthropometric parameters were measured. Finger-prick blood and fresh stool samples were collected for malaria parasites determination, assessment of anaemia and detection of helminths' eggs. Logistic regression analysis was used to investigate the association between these infections and other factors. Overall, 40.6 and 29.6% of children harboured malaria parasites and worms respectively. Prevalences of mild, moderate and severe undernutrition were respectively 22.2, 2.3 and 0.5% for underweight, and 21.9, 7.6 and 2.0% for stunting. In logistic regression analysis, anaemia (OR=2.64, 95% CI: 1.71-4.07) and infection with Ascaris lumbricoides (OR=1.72, 95% CI: 1.01-2.91) were significantly associated with malaria infection. Infection with Trichuris trichiura was significantly associated with increased risks of underweight (OR=2.11, 95% CI: 1.11-4.01). Moreover, rural schoolchildren showed increased chances of carrying worms, compared to their urban counterparts (OR=2.60, 95% CI: 1.75-3.86). Malaria prevention and school-based deworming activities should be re-enforced in Mfou health district to reduce the burden of these infections in children.
