Maternal determinants of diarrhea in children under five in Lubumbashi, Democratic Republic of the Congo.

Diarrheal diseases are one of the leading causes of death among children younger than 5 years of age in the world in general and in sub-Saharan Africa in particular. Mothers are predominantly responsible for child care and housekeeping in this region. The objective of this study was to determine the prevalence of diarrhea and identify its maternal determinants in children under five in the city of Lubumbashi. A cross-sectional study conducted throughout March 2018 collected data from 299 mothers through a household survey. A pretested structured questionnaire was used to collect data in face-to-face interviews. The prevalence of diarrhea in children under 5 in Lubumbashi was 35.8%. In the univariate analysis, the variables associated with diarrhea were single motherhood, soap-free handwashing after latrine use, and the presence of feces around the latrines. Multivariate analysis revealed that the presence of feces around latrines (OR adjusted = 2.12 [1.18-3.80]) was associated with diarrhea. Defective cleaning by mothers, specifically their failure to keep latrine areas clean and free of feces, is associated with the risk of diarrhea in children under five in the study area. A hygiene intervention program must be designed to promote healthy behavior to alleviate the burden of diarrhea in children.

Respiratory health of women selling cassava, corn and soybean flour in Lumbumbashi, Democratic Republic of the Congo.

The aim of this study was to determine the prevalence of respiratory complaints in Congolese women selling grain flours in Lubumbashi. The study enrolled 370 women, including 183 cassava, corn and soybean flour selling women (exposed group) and 187 tax collectors in municipal markets (control group) in Lubumbashi, DRC. A standardized respiratory health questionnaire was used, and a lung function test performed with the use of peak flow-meters. The prevalence of respiratory complaints was markedly higher in dust-exposed women than controls. In addition, peak expiratory flow rate (PEFR) was significantly lower in the exposed group than in controls (342.46 ± 65.62 vs. 410.89 ± 70.91, respectively ; P<0.05). After adjustment for age and education level, women involved in cassava, corn and soybean flour selling business were more likely to develop respiratory complaints ad disorders as compared to controls.

Risk factors for low birth weight in Lubumbashi, Democratic Republic of the Congo.

The aim of this study was to identify the risk factors associated with low birth weight (LBW) in the city of Lubumbashi (DR Congo). This case-control study of singleton births took place from July to December 2014 in 3 referral maternity units in Lubumbashi. The mothers' social and demographic characteristics and medical and obstetric history, especially during this pregnancy, as well as the newborns' sex were compared between the case group (< 2500 g) and the control group. The usual statistics and logistic regression were used to analyze the results. The significance level was set at P < 0.05. We observed that a low educational level (OR adjusted = 2.5 [1.5-4.0]), employment (OR adjusted = 2.0 [1.3-3.1]), lack of prenatal care (OR adjusted = 2.5 [1.5-4.2]), maternal anemia (OR adjusted = 7.6 [2.3-24.8]), malaria during the pregnancy (OR adjusted = 1.5 [1.0-2.3]), urogenital infections during pregnancy (OR adjusted = 1.6 [1.1-2.5]), gestational hypertension (OR adjusted = 2.7 [1.5-4.9]), and maternal malnutrition (OR adjusted = 8.3 [2.4-28.5]) were all significantly associated with LBW. This study shows that some maternal demographic, medical, and obstetric factors influence the birth of LBW infants. Because some of these factors can be addressed and treated, the reduction of neonatal morbidity and mortality associated with LBW requires improving the health care system in our city, including its accessibility.

Blood transfusion rate in Congolese patients with sickle cell anemia.

OBJECTIVE: The main objective of this study was to evaluate the rate of blood transfusion in African Sickle Cell Patients and the risks related to the use of total blood. METHODS: 186 sickle cell patients (95 males and 91 females) aged 0-21 years were regularly followed over a 3 years period in Katanga province, DR Congo. Indications for blood transfusion were mainly based on clinical criteria and Hb level (less than 5g% ml or a drop of 2g% under the steady state value). All the subjects, who were transfused, wer screened for hepatitis B surface antigen (HBs Ag) and Human Immune deficit Virus (HIV). RESULTS: Of 186 patients, 150 (80.6%) were transfused and the average blood transfusion requirement was 0.4 units per patient-year. According to the age of first transfusion, 75.3% (113/150) of them were transfused before the 6th year of life; but the frequency of transfusions seemed to decline in children aged more than 13 years. The risk of HIV infection from blood transfusion was estimated at 1 per 37.1 units or 26 per 1000 blood units. The hepatitis B surface antigen was detected in 15 cases (10%) and HIV serology was positive in 17 patients (11.3%). CONCLUSION: Because of the complications related to blood transfusions in Africa, efforts are needed in order to reduce the frequency of transfusions, by preventive measures (early diagnosis, malarial and penicillin-prophylaxis) and to use more rational indications.
