ABSTRACT
INTRODUCTION: Human immunodeficiency virus (HIV) and tuberculosis (TB) are the leading causes of death from infectious disease worldwide. The prevalence of HIV among children with TB in moderate to high prevalence countries ranges between 10% and 60%. This study aimed to determine the prevalence of HIV infection among children treated for TB in Directly Observed Treatment Short-Course (DOTS) clinics in Lubumbashi and to identify risk of death during this co-infection. METHODS: This is a cross-sectional study of children under-15, treated for tuberculosis from January 1, 2013 to December 31, 2015. Clinical, paraclinical and outcome data were collected in 22 DOTS of Lubumbashi. A statistical comparison was made between dead and survived HIV-infected TB children. We performed the multivariate analyzes and the significance level set at p-value <0.05. RESULTS: A total of 840 children with TB were included. The prevalence of HIV infection was 20.95% (95% CI: 18.34-23.83%). The mortality rate was higher for HIV-infected children (47.73%) compared to HIV-uninfected children (17.02%) (p<0.00001). Age <5 years (aOR=6.50 [1.96-21.50]), a poor nutritional status (aOR=23.55 [8.20-67.64]), and a negative acid-fast bacilli testing (aOR=4.51 [1.08-18.70]) were associated with death during anti-TB treatment. CONCLUSION: TB and HIV co-infection is a reality in pediatric settings in Lubumbashi. High mortality highlights the importance of early management.

INTRODUCTION: overweight and obesity in adolescents are a major global public health issue due to their potential impact on health and increasing frequency. This study aims to determine the prevalence of overweight and obesity among adolescents attending public and private schools in Lubumbashi (DRC). METHODS: we conducted a cross-sectional study of 5341 adolescents aged 10-19 years, 2858 (53.5%) girls and 2483 (46.5%) boys. Weight and height were measured for each adolescent and then body mass index (BMI) was calculated. RESULTS: the average weight was 43,78 ± 11.62 kg (42,39 ± 12.11 kg for boys and 44.95 ± 11.04 kg for girls), the average height was 151,30 ± 13,09 cm (151.20 ± 14.64 cm for boys and 151,38 ± 11.58 cm for girls) and BMI was 18,82 ± 3.15 kg/m² (19.39 ± 3.39 kg/m² for boys and 18.17 ± 2.71 kg/m² for girls). The prevalence of overweight was 8% while that of obesity was 1%. The girls were significantly more affected by overweight (10.7% girls against 5% boys) and obesity (1.5% girls against 0.4% boys) than the boys. CONCLUSION: overweight and obesity in school environment are a reality in Lubumbashi. The prevalence of overweight and obesity in this age group category should be determined in a national evaluation plan in order to implement preventive and therapeutic strategies.

Introduction: le surpoids et l'obésité au cours de l'adolescence constituent un problème préoccupant de santé publique à l'échelle mondiale en raison de leur retentissement potentiel sur la santé et de leur fréquence croissante. La présente étude avait pour objectif de déterminer la prévalence du surpoids et de l'obésité chez les adolescents scolarisés dans les établissements publics et privés à Lubumbashi, en République Démocratique du Congo. Méthodes: il s'agissait d'une étude transversale menée auprès de 5.341 adolescents âgés de 10 à 19 ans, dont 2.858 (53,5%) filles et 2.483 (46,5%) garçons ont constitué notre échantillon. Pour chacun d'eux, nous avons mesuré le poids et la taille puis calculé l'indice de masse corporelle (IMC). Résultats: la moyenne du poids était de 43,78 ± 11,62 kg (soit 42,39 ± 12,11 kg pour les garçons et 44,95 ± 11,04 kg pour les filles), celle de la taille était de 151,30 ± 13,09 cm (soit 151,20 ± 14,64 cm pour les garçons et 151,38 ± 11,58 cm pour les filles) et celle de l'IMC était de 18,82 ± 3,15 kg/m2 (soit 19,39 ± 3,39 kg/m2 pour les garçons et 18,17 ± 2,71 kg/m2 pour les filles). La prévalence du surpoids était de 8% et celle de l'obésité était de 1%. Les filles étaient significativement plus touchées par le surpoids (10,7% filles contre 5% garçons) et l'obésité (1,5 % filles contre 0,4% garçons) que les garçons. Conclusion: le surpoids et l'obésité chez les adolescents en milieu scolaire s'avèrent une réalité à Lubumbashi. La détermination de la prévalence du surpoids et de l'obésité pour cette catégorie d'âge au plan national est recommandable pour leurs préventions et prises en charges

INTRODUCTION: This study aimed to highlight blood pressure (BP) profile in adolescents aged 15-19 years at school in Lubumbashi, Democratic Republic of the Congo. METHODS: We conducted a cross-sectional study of adolescents aged 15-19 years through random sampling of the secondary schools in Lubumbashi during the school years 2013-14, 2014-15 and 2015-16. Blood pressure was measured three times in the same day. RESULTS: Our study included 1766 adolescents aged 15-19 years, of whom 995 were females and 771 boys. Boys' systolic blood pressure was significantly higher than that of girls aged 17, 18 and 19 years. Diastolic blood pressure was not statistically different in all different age groups in both sexes. On the other hand, in both sexes, systolic blood pressure was significantly correlated with body weight, size, body mass index, waist size and heart rate. With regard to diastolic blood pressure, significant correlations were found with body weight and body mass index in girls while heart rate was significantly correlated in both sexes. CONCLUSION: Despite the potential weaknesses of the present study with special regard to its cross-sectional design and to BP measures in the same day, collected data could help health authorities to adopt a national hypertension prevention strategy.

BACKGROUND: The diagnosis of hypertension in children is complex because based on normative values by sex, age and height, and these values vary depending on the environment. Available BP references used, because of the absence of local data, do not correspond to our pediatric population. Accordingly, our study aimed to provide the BP threshold for children and adolescents in Lubumbashi (DRC) and to compare them with German (KIGGS study), Polish (OLAF study) and Chinese (CHNS study) references. METHODS: We conducted a cross-sectional study among 7523 school-children aged 3 to 17 years. The standardized BP measurements were obtained using a validated oscillometric device (Datascope Accutor Plus). After excluding overweight and obese subjects according to the IOTF definition (n = 640), gender-specific SBP and DBP percentiles, which simultaneously accounted for age and height by using an extension of the LMS method, namely GAMLSS, were tabulated. RESULTS: The 50th, 90th and 95th percentiles of SBP and DBP for 3373 boys and 3510 girls were tabulated simultaneously by age and height (5th, 25th, 50th, 75th and 95th height percentile). Before 13 years the 50th and 90th percentiles of SBP for boys were higher compared with those of KIGGS and OLAF, and after they became lower: the difference for adolescents aged 17 years was respectively 8 mmHg (KIGGS) and 4 mmHg (OLAF). Concerning girls, the SBP 50th percentile was close to that of OLAF and KIGGS studies with differences that did not exceed 3 mmHg; whereas the 90th percentile of girls at different ages was high. Our oscillometric 50th and 90th percentiles of SBP and DBP were very high compared to referential ausculatory percentiles of the CHNS study respectively for boys from 8 to 14 mmHg and 7 to 13 mmHg; and for girls from 10 to 16 mmHg and 11 to 16 mmHg. CONCLUSIONS: The proposed BP thresholds percentiles enable early detection and treatment of children and adolescents with high BP and develop a local program of health promotion in schools and family.

INTRODUCTION: Chronic kidney disease is fast becoming a worldwide public health problem due to the increase of hypertension and diabetes mellitus, its main risk factors. In countries like DRC where majority of population are in the low income bracket, very few studies about this disease, usually diagnosed at a very advanced stage have been conducted. As a result of such, cases are not always properly taken care of and managed. METHODS: We opted for a descriptive cross-sectional study and it was conducted during the period from July 2014 to July 2015 at CMDC dialysis service. Were included all patients with glomerular filtration rate lower than 60ml / min / 1,73 m2 or high level of creatinine longer than three months during the study period Goal. This study aims at describing the sociodemographic characteristics, risk factors and biological parameters of patients admitted for kidney failure. RESULTS: We selected 60 patients. The average age was 51, 38 + / _ 13, 47 with the most affected included age group between 50-59 years. 51, 67% had completed secondary education and 40% higher. Risk factors of renal damage were the HTA 66, 64%, 25% diabetes mellitus, use of nephrotoxic products 35%, HIV infection 11, 67%, 10% obesity, sickle cell disease 3, 3%. The birth weight birth of our patients as well as existing renal disease in family were unknown factors. 85% of our patients had hemoglobin levels below 12 g%. CONCLUSION: From this observation, it appears that the age of our patients did not differ from that observed in other low-income communities. The level of education of our patients is higher compared to other studies. It would be better to develop strategies for early detection of kidney disease to avoid ending hemodialysis remains a very expensive treatment.
