Significant associations (p<0.05) are shown in bold. Basic model was adjusted for sex, age, and body mass index (BMI). Besides sex, age, and BMI, considered variables in the stepwise selection model (combined forward and backward selection) were: season, education, hypertension, diabetes, asthma, chronic obstructive pulmonary disease (COPD), difficulties with walking, pain or physical complaints, and anxiety/depression. Models with the lowest Akaike information criterion (AIC) are shown.
1Model additionally adjusted for average recorded wear time/day.
xCovariate did not remain in main model.
