title: [Reference values for maximal midexpiratory flow in black females].
abstract: The aim of this publication is to contribute to the establishment of reference values for the forced expiratory flow between 25 and 75% of the vital capacity (FEF25-75) among black females in West Africa. 316 of them, aged between 10 and 70 years, were submitted to this test. They were considered free from cardiopulmonary disease after a questionnaire and clinical examination. FEF25-75 in absolute value was lower than in the white Euro-americans. It increased up to 18-19 years of age, then decreased steadily thereafter. The main equations of regression for the FEF25-75 (l X s-1) were: 10-18 years, 0.177A + 1.058 and 0.157A + 0.826H + 0.005; 19-70 years, -0.028A + 4.211 and -0.025A + 2.206H + 0.512, (where A is the age in years and H the height in metres). The results are compared with the reference values published in Black Africa, Europe and the United States.
