Notes. BMI = body mass index; COPD = chronic obstructive pulmonary disease; OR = odds ratio; PEF = peak expiratory flow.

Model 1 adjusted for age, sex, education, race, ethnicity, and height. For PEF < 80%, age, sex, race, ethnicity, and height were not included as covariates given that the prediction equations for PEF < 80% is based on these variables. Model 2 includes Model 1 covariates and ever and current smoking, moderate physical activity, BMI, COPD, stroke, heart disease, hypertension, diabetes, cancer, arthritis, and psychiatric disorders. Model 3 includes Model 2 covariates and all five factors in the same model. βs are from linear regressions predicting continuous PEF; OR from logistic regressions predicting PEF < 80% of the predicted value.
