Assignment of risk level for the assessed modifiable risk factors

Risk domain	Risk level	Cut points
Alcohol consumption
	Low	Not drinking alcohol, or no more than 2 standard drinks per occasion
	Medium	14 or less standard drinks per week and either more than 2 standard drinks per occasion
	High	More than 14 standard drinks per week
Blood pressure, cholesterol and diabetes management
	Low	No diagnosis and regular check-ups; or diagnosis and medically managed
	Medium	Unsure of diagnosis but have regular check-ups; or diagnosis with regular check-ups and working toward managing it
	High	Diagnosis but no regular check-ups and/or medical management; or no diagnosis and no regular check-ups
Body mass index (weight in kgs/height in metres)
	Low	18 to 24.9
	Medium	25 to 29.9; or less than 18
	High	30 or over
Adherence to the MIND diet (score range 0:14)
	Low	12 or higher
	Medium	7.5 to 11.9
	High	Less than 7.5
Smoking
	Low	Not smoking
	Medium	Occasional smoking
	High	Smoking once or more a week
Physical activity (METs)
	Low	600 or more
	High	Less than 600
Cognitive activity (frequency of 11 cultural and cognitive activities)
	Low	33 or higher
	High	Less than 33

MIND: Mediterranean-DASH Intervention for Neurodegenerative Delay diet (excluding wine consumption) [37] was scored by summing the 15 component scores. Physical activity assessed based on METS: metabolic equivalent of tasks, where light, moderate and vigorous activity minutes were assigned scores of 3.3, 4 and 8 respectively; 600 MET = sufficient (low risk) if ≥ 150 min of moderate activity per week. Cognitive activity items were adapted from the ANU-ADRI (32); with sufficient (low risk) indicated when ‘several times a month’ (3) was selected for 11 cognitively stimulating activities.
