  1. Note. PEF = peak expiratory flow. HRS = Health and Retirement Study. MIDUS = Midlife in the United States study. WLS = Wisconsin Longitudinal Study. NHATS = National Health and Aging Trends Study. ELSA = English Longitudinal Study of Ageing. SHARE = Survey of Health, Ageing and Retirement in Europe. Coefficients are either standardized βs linear regression (Maximum PEF, Proportion of Predicted PEF) or odd ratios (OR) and 95% confidence intervals (CI) from logistic regression (Proportion of Predicted PEF < 80%). Model 1 controlled for age, sex, race, ethnicity, height and education and Model 2 was Model 1 with the addition of behavioral (smoking, physical activity) and clinical (body mass index, depression) factors. Proportion of predicted PEF controlled for race, ethnicity, and education. All analyses of WLS also included a control variable for sample type (respondent/sibling). Sample size is smaller for Model 2 because of missing data on the behavioral and clinical covariates
