  Aim: To develop the novel regression equations that predict spirometric parameters (SPs) in concert with aging-specific corrections for four explanatory variables, including age, height, body weight, and fat fraction of body mass. Subjects: A large cohort of nonsmoking, non-obese, healthy adults in the general population in Japan (males: 3,056, females: 6,783). Methods: Supposing that SP is described by an aging-dependent, logarithmic, additive function of age, height, body weight, and fat fraction of body mass, gender- and aging-specific regression equations predicting the forced vital capacity (FVC), forced expiratory volume after one second (FEV1), FEV1/FVC, peak expiratory flow rate (PEF), forced expiratory flow rate at 50% expiration of the FVC (FEF50), and forced expiratory flow rate at 75% expiration of the FVC (FEF75) were established. The partial regression coefficients of ex.. View More»
