Design outcomes

Primary

Measure	Time frame
The following primary outcome measures were assessed at baseline and 6 months (23 - 25 weeks) follow-up: 1. Cognitive healthy behaviors were measured with a previously validated composite measure comprised of an average of six z-scores of lifestyle factors related to dementia risk: physical activity, social activity, diet, cardiovascular care, smoking, and alcohol intake 2. Healthcare providers’ practices toward dementia prevention was measured using interviews in which older adult participants were asked if a healthcare provider has talked with them about ways to prevent AD or dementia (Yes, No/I don’t know) and if a healthcare provider have referred them to at least one of six different dementia risk factor management recommendations in the last six months (hypertension, weight or diet, cholesterol, hearing loss, depression, sleeping problems, or memory complaints management) 3. Memory was measured using the Memory Impairment Screen (MIS) scale that measures delayed free- and cued-recall 4. Executive functioning was measured using an alternative trail-making test, visuoconstruction skills (cube and clock drawing tests), verbal fluency (number of words in a minute), and abstraction (word-pairing) 5. The number of cases with mild-to-moderate cognitive impairment measured using the Montreal Cognitive Assessment (MoCA <22 pts)	—

Secondary

Measure	Time frame
Dementia prevention beliefs measured using 10 items, five-point Liker scale (higher score reflecting more positive beliefs), if they knew ways to prevent AD or dementia (Yes, No/I don’t know), and if they had asked a healthcare provider about ways to prevent AD or dementia (Yes, No) at baseline and 6 months (23 - 25 weeks) follow-up	—
