Participants are randomized in a 1:1 ratio to Group A (tailored lifestyle intervention) or Group B (general health advice) for a duration of 12 months. The lifestyle intervention comprises three parts 1) Lifestyle coaching, 2) a voucher program, and 3) online self-management. Group B will receive general health advice.

Trial outcomes
Primary outcomes
Lifestyle for BRAin Health (LIBRA) score 2
1-year change in the Lifestyle for BRAin Health (LIBRA) score 2. This is a weighted score of fifteen lifestyle-related risk factors that are proven to be associated with increased dementia risk. Higher score means a greater risk for dementia. Scored from -6.1 to 25.8 (absolute weight).
Secondary outcomes
15-Word Verbal Learning Test
Measure of immediate and delayed memory. Wordlist is presented five times in a row and asked to be recalled immediately and after 15 minutes. Discrete number; score: 0-15 (higher score means a better outcome)
Digit Symbol Substitution Test (DSST)
Measure of attention/processing speed, number of correctly matched symbols to digits within 90 seconds. Discrete number; 0-90 (higher score means a better outcome).
Wechsler Adult Intelligent Scale (WAIS) digit span
Measure of working memory. Scored as the maximum number of digits repeated correctly. Discrete number; 0-14 (higher score means a better outcome).
Trail Making Test
Measure of attention and executive function. Task A and B. Time taken to complete the test; minimum 0, no maximum, lower score means a better outcome.
Other outcomes
