Units for adjusted means (Adj Mean) and Beta estimates are Sq Cm

Model 1 adjusts for age, sex, race, education, and height

Model 2: Model 1 + smoking status (yes/no) and pack years smoked

Model 3: Model 2 + physical activity, sedentary behavior, depressive symptoms

Model 4: Model 3 + body mass index (height removed from model)

Categorical chronic stress variable was entered into linear regression model as continuous variable to evaluate p-trend.
