Aims: Determine factors associated with malaria infection, the prevalence of asymptomatic carriage of malaria parasites and fevers of non malarial origin. Study Design: This was a cross-sectional study.

IntroductionThe aim of this study was to assess the prevalence of malnutrition among HIV infected children under five years of age followed up at the Laquintinie Hospital Douala (LHD).MethodsMedical records of children aged 13 days-59 months enrolled at initiation of antiretroviral treatment in the Day Care Unit/LHD, were reviewed for a period of 14 years (from 2002 to 2015). We used standard Z-scores, with cut-off point of <-2 SD to define low height-for-age (HAZ), low weight-for-height (WHZ) and low weight-for-age (WAZ). Factors associated with malnutrition were assessed according to World Health Organization (WHO) criteria.ResultsOverall, 217 medical records were included and 52.5% were records of boys. The median weight, height and age of the children was 9.5 kg (range: 2.5-20), 76 cm (range: 46- 117) and 22 months (range: 0.03-59), respectively. The overall prevalence of malnutrition among HIV-infected children was 68.7%; 63.6% were stunted (HAZ<-2), 37.8% were underweight (WAZ<-2) and 18.4 % were wasted (WHZ<-2). Severe and advanced immunological stages of HIV according to WHO were found in 42.4%, (39/92) and 17.4%, (16/92) of children respectively, and most of them (21.7%) were aged 12-36 months. The overall prevalence of anemia, oropharyngeal candidiasis and pulmonary tuberculosis were 34.6%, 12% and 8.8%, respectively. Oropharyngeal candidiasis was a risk factor independently associated with severe underweight and wasting (OR = 4.9, 95% CI: 1.8-13.5, p = 0.002) and (OR = 5.1, 95% CI: 1.5-17.1, p = 0.007).ConclusionHIV infection negatively affects the nutritional status of children under five years of age. Early detection of malnutrition is necessary and adequate nutrition should be integrated into the management of pediatric HIV.

Malaria remains a major health problem in Cameroon; It accounts for 38% of consultations, 24% of deaths and 36.8% of absenteeism in the country. The negative economic impact of malaria has encouraged a new control approach targeting companies. In this regard, a cross sectional study was conducted from February 2015 to June 2017 in 14 companies in the town of Douala. This study aimed at determining the prevalence, control practices of employees and identifying associated factors with malaria. A total of 2705 workers were interviewed and systematically screened for malaria using LED fluorescence microscopy (CyScope®). All positive cases were given a malaria treatment. The prevalence of malaria and asymptomatic malaria was 30.1% and 28.9% respectively; asymptomatic malaria accounted for 95.7% of all positive diagnostic test. Malaria infection was significantly higher in employees aged 36–60 years (30.5%) and having completed primary studies (36%). ITNs ownership and utilization were 86.36% and 77.23% respectively. The risk for malaria infection has significantly decreased with age and educational level while the employees’ level of education and size of households were significantly associated with the regular utilization of ITNs. This is the first study assessing malaria prevalence and risk factors in workplace in Cameroon and using a novel diagnostic tool. This study outlines a high prevalence of malaria infection, especially asymptomatic carriage, high rates of ITNs ownership and utilization, as well as the influence of level of education, age and household size as associated factors. Active case detection of asymptomatic carriers through systematic screening of employees at workplace and their treatment is feasible with the Cyscope microscope and could be a good complement to ongoing control strategies.

Background. Malaria and malnutrition are major public health problems in developing countries. This studywas mainly focused on the prevalence, patterns, and predictors of these conditions and their associations. Methods. A cross-sectional community study was conducted from February to March 2018 among 281 participants living in two districts in Douala. A questionnaire was used to collect sociodemographic information and parasitological and anthropometric data of participants. Nutritional status was determined using age, weight, and height. Body mass index for age (BMIAZ), height-for-age (HAZ), weight-for-age (WAZ), and weight-for-height (WHZ) Z scores were computed based on the World Health Organization growth reference curves. Malaria infection was diagnosed using light-emitting diode fluorescence microscopy. Results. The overall prevalence of malaria was 18.9%, mostly asymptomatic cases. Malaria infection was associated with study site ( p = 0.04 ), age ( p = 0.01 ), WAZ ( p = 0.0049 ), HAZ ( p = 0.03 ), and BMI ( p = 0.02 ). The overall prevalence of malnutrition was 43.1%, and stunting was the main form of malnutrition recorded in children under five years of age (23.6%). The risk of being stunted in this group was about quintupled in malaria-infected participants ( ARR = 4.70 ; p = 0.02 ). In those aged 5-19 years, the prevalence of underweight was significantly higher in malaria-positive individuals as compared to their negative counterparts ( p = 0.02 ). The overall prevalence of malaria and malnutrition cooccurrence was 8.5% and varied with age ( p < 0.0001 ) and study site ( p = 0.04 ). Conclusion and Recommendation. Malaria was associated with malnutrition among the study participants. Early detection and treatment of these ailments would reduce morbidity and mortality.
