↵3-150 Any past or current environmental tobacco smoke (ETS).
↵3-160 Models are adjusted for community, grade, spirometer, technician, log (height), age, sex, race, weight and weight2, two way interactions of sex and grade with age, race, log (height), weight and weight2 and selected medical and household characteristics.
PFT = pulmonary function test; FEV1 = forced expiratory volume in one second; FVC = forced vital capacity; PEFR = peak expiratory flow rate; MMEF = mean mid expiratory flow; FEF = forced expiratory flow.
