Objective: To evaluate the prevalence and determinants of overall cardiovascular risk among the pygmies of Congo Brazzaville. Methods: Cross-analysis of anthropometric data, clinical and laboratory 273 indigenous subjects including 54 patients with cardiovascular disease (CVD) and 183 without CVD, aged 29 to 69 years. The cardiovascular risk stratification table WHO/ISH 2003 was used to assess overall cardiovascular risk level. Multiple logistic regression was used to assess the independent determinants of cardiovascular risk using the global left ventricular hypertrophy as a marker. Results: Fifty-four subjects had cardiovascular disease (CVD), including 31 women (36.7%). They were aged 51.9 ± 12.4 years (p < 0.05) and showed a high blood pressure in shortlong (100 ± 77 vs 32 ± 48 months; p < 0.001). It was also found a pulse pressure, PPO (58 ± 8 vs 51 ± 4 mmHg). In multivariate analysis, HDL-C levels, fasting glucose, age greater than 50 years and the higher parity or equalizes to 5 among women have emerged as key determinants of CVD risk. Conclusion: Whatever the stage, arterial hypertension in this study is associated at the risk of cardiovascular diseases (CVD) high at the Pygmies of Congo, emphasizing the need for a more aggressive follow-up strategy.
L’objectif de cette étude était d’évaluer les apports nutritionnels et la dépense énergétique des athlètes congolais internés et engagés au Semi-Marathon International de Brazzaville (SMIB). 40 athlètes (femmes et hommes) âgés respectivement de 22,60 ± 3,45 ans et 28,48 ± 8,18 ans, ont participé à cette étude exploratoire. La méthode du « semainier de trois jours consécutifs » pour collecter les données alimentaires et la « formule de Harris et Benedict » pour calculer la dépense énergétique des athlètes étaient utilisées. Les tables de composition alimentaires ont servi pour convertir les macronutriments. Résultats: les pourcentages des glucides (68,27% et 61,4%) étaient normaux, tandis que ceux des lipides (14,39% et 16,49%) et protéines (17,34% et 22,11%) étaient loin des recommandations. L’apport énergétique des femmes était supérieur à la dépense (3423,4 Kcal vs 2256,01 Kcal). La quantité d’énergie apportée chez les hommes était inférieure à la dépense (2980,93 Kcal vs 3181,90 Kcal). Les performances (1h 11’33’’, 1h 13’58’’ et 1h 22’27’ et 1h 15’43’’) étaient faibles. Conclusion : la balance énergétique des athlètes était déséquilibrée, avec une alimentation hyperprotéique et hypo lipidique. Cette alimentation est source de fatigue nerveuse, de mauvaise récupération et constitue un facteur limitant de la performance sportive. The objective of this study was to evaluate the nutritional intake and energy expenditure of Congolese athletes interned and engaged in the Brazzaville International Half-Marathon (BIHM). 40 athletes (women and men) aged 22.60 ± 3.45 years and 28.48 ± 8.18 years respectively participated in this exploratory study. The “three consecutive day week planner” method of three consecutive days” to collect dietary data and the “Harris and Benedict formula” to calculate the athletes' energy expenditure were used. Food composition tables were used to determine the weight of foods and the conversion of their macronutrients. Results: the percentages of carbohydrates (68.27% and 61.4%) were normal, while those of lipids (14.39% and 16.49%) and proteins (17.34% and 22.11%) were away from recommendations. The energy intake of women was higher than the expenditure (3423.4 Kcal vs 2256.01 Kcal). The amount of energy provided in men was lower than the expenditure (2980.93 Kcal vs 3181.90 Kcal). The performances (1 h 11'33'', 1 h 13'58'' and 1 h 22'27' and 1 h 15'43'') were low. Conclusion: the energy balance of the athletes was unbalanced, with a high protein and low lipid diet. This diet is a source of nervous fatigue, poor recovery and is a limiting factor in sports performance.
Biochemical parameters are useful in the diagnosis of many health abnormalities in athletes. Some studies suggest training well and eating a balanced diet to improve performance. The modification of biochemical parameters during endurance races has not yet been studied in many African countries. Our objective was to evaluate the dietary profile and the effects of competition on the biochemical parameters of Congolese endurance athletes. The method used was the questionnaire for the food profile and blood samples were taken to measure the biochemical parameters of the athletes. A total of 64 athletes, i.e. 20 girls and 44 boys divided into two groups (group 1 or experimental group (EG), 32 endurance athletes and group 2 or control group (CG), 32 walkers who participated in a cross-sectional study in Brazzaville. The subjects were respectively 26.16 ± 2.79 years old for the EG and 27.44 ± 3.34 years old for the CG. The results indicated that quality foods were difficult to access. The main course was more consumed compared to the starter and dessert (60% of girls and 63.63 of boys). However, biochemical parameters showed a significantly lower serum creatinine concentration in EG subjects compared to CG subjects (0.86 ± 0.06 mg/dl vs 1.04 ± 0.16 mg/dl; t = −5.95; p < 0.000), the triglyceride level of EG subjects was slightly lower (0.
Context: Automobile pollution is becoming a potential threat to the cardiorespiratory health of the urban population of sub-Saharan Africa. The present study aims to evaluate the level of concentrations of fine particles (PM2.5 and PM10) near road traffic and the effects of exposure to automobile pollutants on pulmonary function and arteriolar blood oxygen saturation among sellers around road traffic. Materials and Methods: The study recruited 48 healthy people carrying out a sales activity near road traffic. PM2.5 and PM10 measurements were taken from 6 a.m. to 6 p.m. using a Temtop Airing-1000 portable particle detector. Spirometric measurements were taken in the morning and in the evening from a portable Spirobank G spirometer. Oxygen saturation measurements were also taken in the morning and evening using a Pulse oxymeter CMS50D pulse oxymeter. Results: Mean values of forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), and forced expiratory flow between 25% and 75% of forced vital capacity (FEF25 -75) recorded in the evening were significantly lower than those obtained in the morning in the subjects of the total group and in the men. Only the mean values of PEF and FEF25 -75 obtained in the evening were significantly lower than those recorded in the morning in women. Minimum PM2.5 values recorded near road traffic were negatively correlated with evening PEF in men, while maximum PM10 values were negatively correlated with evening PEF in women. The blood oxygen saturation recorded in the evening How to cite this paper:
RESUMEObjectif : appréhender la consommation du Dioscorea librechtsiana De Wild et ses facteurs limitatifs. Méthodologie et Résultats : L'étude a concerné 199 ménages dont un répondant par ménage. En leur absence les chefs de ménage étaient remplacés systématiquement par leurs conjoints (es) et/ou par leur enfant dont l'âge était supérieur à 17 ans. Le choix de l'échantillon a été fait par un tirage aléatoire simple dans les quartiers de Brazzaville choisis au hasard. Les parcelles à enquêter ont été sélectionnées aléatoirement. : 83,08% des sujets consomment le Ntinia par contre 16,92% ne le consomment pas. Sur 33 enquêtés qui ne consomment pas cet aliment, 21 ont donné leurs raisons. : 80,95% ont évoqué le dégout, 9,52% des tabous sur le plan gastronomique, les habitudes alimentaires et 4, 76% autres. Conclusion et application des résultats : Le Dioscoréa liebrechtsiana De Wild « Ntinia » est un aliment qui est consommé dans la plupart des ménages de Brazzaville. Certaines pathologies sont guéries par cet aliment qui présente des vertus médicinales et contient des substances nutritives pour l'Homme.
