LTPA: leisure-time physical activity. MET: metabolic equivalent of task. Presented betas are based on square-root-transformed MET hours/week from moderate- and vigorous-intensity physical activity. Estimates are modeled separately for education and occupational class and adjusted for age.
The overall test for interaction is a likelihood ratio test comparing the models with and without interaction terms.
