aHR: hazard ratio.

bThe first instance of nonuse attrition during months 1 to 2. The following baseline variables were included in the initial multivariate model but did not remain significantly associated with early nonuse attrition following a backward stepwise selection procedure: education, history of cardiovascular disease, history of diabetes, history of hypertension, Geriatric Depression Scale score, and verbal fluency score.

cref: reference.

dN/A: not applicable.

eHigher scores indicate better chronic disease self-management.

fThe first instance of nonuse attrition from month 3 onward. The analysis included individuals who had not already undergone an episode of nonuse attrition during the first 2 months. The following variables were included in the initial multivariate model but did not remain significantly associated with late nonuse attrition following a backward stepwise selection procedure: education, current smoking, obesity, age, Mini Mental Status Examination score, verbal fluency score, Stroop score, Rey Auditory Verbal Learning Test recall score, Short Physical Performance Battery score, Partners in Health score, and Mediterranean Diet Adherence Screener nutrition score.
