    Contexte & objectif. La dimension nutritionnelle du confinement instaurĂ© Ă  l’occasion de la pandĂ©mie COVID-19 n’a pas encore Ă©tait Ă©tudiĂ©e en milieu africain. La prĂ©sente Ă©tude a pour objectifs d’identifier et analyser les caractĂ©ristiques nutritionnelles chez l’adulte actif et la personne ĂągĂ©e congolais pour dĂ©pister d’éventuelles carences. MĂ©thodes. Dans une enquĂȘte transversale menĂ©e lors du second confinement entre avril et mai 2020, quelques mĂ©nages de Bacongo (Brazzaville, Congo) recrutĂ©s alĂ©atoirement, ont Ă©tĂ© interviewĂ©s sur base d’un questionnaire de type alimentaire quantitatif. Elle portait sur la nature et la quantitĂ© des aliments consommĂ©s durant toute la journĂ©e, du lever au coucher. Les apports quotidiens ont Ă©tĂ© calculĂ©s, et rendus en termes de % d’énergie fournie respectivement par les glucides, les lipides et les protides ; ainsi que les oligo-Ă©lĂ©ments, et les vitamines (A, B et C). RĂ©sultats. La valeur nutritionnelle moyenne globale Ă©tait de 2123,5 ± 494,5 Kcal, chez les 183 sujets inclus (107 adultes en activitĂ© professionnelle ĂągĂ©s entre 31 et 59 and et 76 personnes ĂągĂ©es de 66 Ă  80 ans). SpĂ©cifiquement, les besoins en glucides Ă©taient couverts Ă  hauteur de 81,5 %, tandis que ceux en protĂ©ines et en lipides Ă©taient insuffisants, respectivement de l’ordre 33,5 g/j et 59,5 g/j en moyenne. Les apports en calcium, phosphore, et magnĂ©sium, Ă©taient conformes aux normes recommandĂ©es, Ă©tant  respectivement : de 613,9 mg, 709,8 mg et 267,5 mg. Les apports en fer se situaient Ă  la limite infĂ©rieure de la normale (7,7 mg) chez les sujets ĂągĂ©s de plus de 66 ans. Les apports en vitamines A et C Ă©taient satisfaisants, tandis qu’un risque de carence Ă©tait observĂ© pour les vitamines B1 et B2, dans le groupe des sujets ĂągĂ©s de 31 Ă  59 ans (0,17 mg et 0,58 mg). Conclusion. Ces observations suggĂšrent un effet nĂ©gatif du confinement dans le domaine nutritionnel, justifiant des stratĂ©gies adaptĂ©es de supplĂ©mentation alimentaire, en vue de renforcer les capacitĂ©s immunitaires dans la population exposĂ©e. Context & objective. Nutritional impact of lockdown due to the COVID-19 pandemic has not yet been studied in African environment. This study aimed to analyze the nutritional characteristics of active adults and the elderly Congolese to screen for possible deficiencies. Methods. The cross-sectional survey was carried out between April and May 2020, during the 2nd Covid-19 lockdown. Few households in Bacongo (Brazzaville) were randomly recruited and interviewed, using a quantitative food-type questionnaire, adressing the nature and quantity of food consumed throughout the day. Daily intakes were measured and reported as percentage of energy supplied respectively by carbohydrates, lipids and proteins; as well as trace elements, and few vitamins. Results. The overall average nutritional value around 2123.5 ± 494.5 kcal reflects an insufficient intake; specifically for proteins (33,5g/d) and fat (59,5g/d) requirements, except for carbohydrates (81,5%). The intakes of calcium (613.9 mg), phosphorus (709,8 mg), and magnesium (267,5 mg) met the recommended standards. Iron intakes were at the lower limit of normal (7.7 mg) in subjects aged more than 66 yrs to. Vitamin intakes were relevant for vitamins A and C, while slightly deficient in subjects aged 31-59 yrs for vitamins B1 and B2. Conclusion. The present observations suggest a negative nutritional impact of lockdown, highlighting the need for targeted nutritional strategies of food supplementation

    Notre Ă©tude avait pour objectif d’évaluer l’énergie apportĂ©e par les aliments consommĂ©s par les adolescents de l’école congolaise de Basket-ball (GAMETIME) pendant la pĂ©riode d’entrainement et comparer ces apports aux normes recommandĂ©es par les nutritionnistes. Une enquĂȘte de consommation alimentaire a Ă©tĂ© menĂ©e auprĂšs de 10 joueurs dont l’ñge moyen Ă©tait de 15,03 ± 3,65 ans. Le poids moyen Ă©tait de 41,57 ± 5,18kg, tandis que la taille moyenne des sujets Ă©tait de 1,69 ± 0,09m.  La mĂ©thode utilisĂ©e Ă©tait celle de rappel de 24 heures. Les rĂ©sultats ont indiquĂ© que 70% des sujets prennent 2 repas par jour et ces repas sont constituĂ©s de dĂ©jeuner (60%) et du diner (30%). Toutefois, l’apport nutritionnel trouvĂ© Ă©tait de 3717,12 kilocalories. Tandis que la dĂ©pense Ă©nergĂ©tique Ă©tait estimĂ©e Ă  2827,29 ±128,87 kilocalories. Par ailleurs, les pourcentages des apports Ă©taient respectivement de 68,95 % en glucides (˃ Ă  60 %), de   19,52 % en lipides (< Ă  30 %) et de 11,53 % en protides (< Ă  15 %). Cependant, les apports Ă©nergĂ©tiques trouvĂ©s Ă©taient supĂ©rieurs aux dĂ©penses Ă©nergĂ©tiques, soit une diffĂ©rence de 889,83 ± 3,38 kilocalories a Ă©tĂ© constatĂ©e. La balance Ă©nergĂ©tique Ă©tait plus dominĂ©e par des apports que des dĂ©penses. Ces apports rĂ©pondaient superficiellement aux normes recommandĂ©es. En conclusion, l’apport en macronutriment a montrĂ© des pourcentages incohĂ©rents par rapport aux normes recommandĂ©s. L’alimentation des basketteurs adolescents congolais Ă©tait non seulement hyper glucidique mais malheureusement hypo lipidique et hypo protĂ©ique. Ces macronutriments dĂ©sĂ©quilibrĂ©s sont considĂ©rĂ©s comme facteurs limitants de performance. Our study aimed to evaluate the energy provided by the foods consumed by adolescents from the Congolese basketball school (GAMETIME) during the training period and to compare these contributions to the standards recommended by nutritionists. A food consumption survey was conducted among 10 players whose average age was 15.03 ± 3.65 years. The average weight was 41.57 ± 5.18 kg, while the average height of the subjects was 1.69 ± 0.09 m. The method used was the 24 hour callback. The results indicated that 70% of the subjects took 2 meals per day and these meals consisted of lunch (60%) and dinner (30%). However, the nutrient intake found was 3717.12 kilocalories. While the energy expenditure was estimated at 2827.29 ± 128.87 kilocalories. In addition, the percentages of intakes were respectively 68.95% in carbohydrates (˃ to 60%), 19.52% in lipids (<30%) and 11.53% in proteins (<15%). However, the energy intake found was greater than the energy expenditure, a difference of 889.83 ± 3.38 kilocalories was observed. The energy balance was more dominated by intakes than expenditures. These contributions superficially met the recommended standards. In conclusion, the macronutrient intake showed inconsisten percentages compared to the recommended standards. The diet of Congolese adolescent basketball players was not only high in carbohydrates but unfortunately low in fat and low in protein. These imbalanced macronutrients are considered as performance limiting factors
