Lung function in young Nigerian adults.
Static and dynamic long volumes have been measured in 181 (123 males and 58 females) apparently healthy Nigerian adults. The age range in both sexes was between 17 and 34 years (22.0 +/- 3.2 years in males and 21.3 +/- 3.2 years in females). In the male subjects mean height, weight and body surface area were 170.0 +/- 6.0 cm, 62.0 +/- 8.5 kg and 1.72 +/- 0.19 m2 respectively. In the female subjects mean height, was 162.3 +/- 15.3 cm, mean weight was 57.2 +/- 8.4 kg and mean body surface area was 1.60 +/- 0.12 m2. In both sexes, caucasian prediction formulae overestimated the TLC, FVC and RV/TLC% of the subjects. Observed FEV % in our subjects was higher than in the caucasians. The elevated FEV1 % and reduced FVC, RV/TLC % and TLC in Nigerian subjects may suggest and increased elastic recoil of the lungs and chestwall in them. Regression coefficients and constants for predicting TLC, FVC, FEV1, IC, ERV and RV in Nigerian subjects are presented.
