No studies on the spirometric profile of obese adolescents in sub-Saharan Africa exist. The objectives of the study are: 1) to determine and compare the ventilatory values, the forced expiratory flow rates and the pulmonary reports with the reference values; 2) determine the percentages of subjects with abnormal ventilatory volumes, or an obstructive ventilatory deficit, or a static pulmonary distension; 3) examine the impact of anthropometric parameters and body composition on FEV1 and FVC in school children aged 11 - 18 years. A total of 1,138 obese adolescents (412 boys and 726 girls), belonging to 132 colleges and high schools in Brazzaville, participated in the study. They were selected by a 2-degree cluster survey on the obesity criterion. Spirometric values were measured according to the recommendations of scientific societies, as well as the definitions of respiratory anomalies. The results showed that all forced respiratory rates were reduced, the lung volumes (FVC, VC, IC, TPC) were increased compared to normal values, as well as the FEV1 / CVF and CI / CPT ratios. In addition,83.7% of cases (n = 952) of obstructive ventilatory deficit were found. Among the cases of moderate ventilatory deficit (n = 186), 29.5% of cases (n = 54) of mixed ventilatory deficit were found. In conclusion, obesity affect respiratory function. This study provides the health authorities with valid authorities to fight this scourge which increasingly affect school adolescents.
