Assessment of dementia risk‐related factors

Risk factor	Assessment
Continuous variables a
Alcohol	Number of standard drinks per drinking occasion x drinking frequency per week
BMI	Weight in kilograms divided by height in meters squared
MIND diet	Adherence to the Mediterranean‐DASH Intervention for Neurodegenerative Delay (MIND) diet excluding wine consumption 52 ; 0, 0.5, or 1 point was given to each category; total MIND score (range 0‐14) calculated by adding all sub‐scores
LSNS Totalb	The 18‐item Lubben Social Networks Scale (LSNS‐18; 53 ). Equally weighted responses from three subscales summed to produce an overall score (range 0‐90)
‐LSNS Friendsb	LSNS‐18 subscale assessing size and supportiveness of friends network (range 0‐30)
‐LSNS Relativesb	LSNS‐18 subscale assessing size and supportiveness of relatives network (range 0‐30)
‐LSNS Neighborsb	LSNS‐18 subscale assessing size and supportiveness of neighbors network (range 0‐30)
Cognitive activity	Frequency of 11 different cognitive activities (range 0‐55): reading, participating in craft or similar activities, playing games, writing, socializing, using online social networks, participating in “brain training” activities, visiting a library/museum/gallery/exhibition/talk, learning new music or dance, attending a concert/play/musical, and undertaking study or courses 54
Depressionb	The Hospital Anxiety and Depression Scale (HADS). 55 Provides normative cut‐points for normal (0‐7), borderline (8‐10), and high (11‐21) risk of clinical anxiety and depression
Anxietyb,c	HADS (as above)
Physical activity	Minutes per week of walking, moderate, and vigorous activity were assessed (at least 10 minutes at a time). A score of 3.3, 4, and 8 metabolic equivalent of tasks (METs) was given to each minute of walking, moderate, and vigorous activity respectively per week to calculate sub‐scores. 56 Total physical activity score was calculated by summing the sub‐scores.
Categorical variables a
Inattention to Cholesterol	Diagnosis of high cholesterol, having check‐ups, and management were assessed. Low risk was assigned for participants reporting no diagnosis and regular check‐ups, or those with diagnosis but managing the condition; high risk was assigned to participants with diagnosis but no regular check‐ups and/or insufficient management, or participants without diagnosis but no regular check‐ups.
Inattention to Diabetes	Diagnosis of diabetes, having check‐ups, and management were assessed. Low and high risk were assigned as above (cholesterol)
Smoking	Frequency of smoking was assessed. Low risk was assigned to participants who do not smoke; high risk was assigned for participants who smoke (any frequency).
Inattention to Blood pressure	Diagnosis of hypertension, having check‐ups, and management were assessed. Low and high risk were assigned as above (cholesterol)
