Factors affecting ventilatory lung function in young Navy selectees.
Ventilatory lung function was studied in 528 Navy selectees 16 to 23 yr of age. Analysis of the pulmonary function data indicated that height and chest circumference were the best "predictors" of forced vital capacity (FVC) and forced expiratory volume in one second (FEV1). Other factors, such as amount of sports activity, ethnicity, weight, or Quetelet index, were of minimal predictive value. Linear prediction formulas of ventilatory lung function for young male adults of this age range were derived. Analysis of variance showed that the apparently greater FVC found in smokers than that found in nonsmokers was related to the smokers being older and consequently taller than the nonsmokers. After adjusting for age (even in this narrow age range) and height, no difference in pulmonary function between the 2 groups could be demonstrated.
