Plain language summary
Older people are at high risk of cardiovascular disease, and 90% of the risk factors can be modified, including an unhealthy diet, poor physical activity, obesity, smoking, and obesity-related comorbidities. This randomised controlled trial examined a multifactorial approach combining several lifestyle modifications in 1259 older adults between 60 and 77 years of age to reduce the risk of cardiovascular disease. Participants were randomly assigned to intensive multi-domain lifestyle intervention or regular health advice control groups. The multifactorial lifestyle intervention incorporated dietary counselling, exercise training, cognitive training, and managing CVD and metabolic risk factors. Dietary interventions included tailored strategies that considered increased consumption of fruits, berries, vegetables, whole grains, margarine, oil, and fish. Physical exercise interventions included strength training, balance exercises, and aerobic exercises. Cognitive interventions and intensive strategies to manage metabolic factors were also implemented. In the multifactorial lifestyle intervention group, cerebrovascular events were lower after two years than in the control group. In addition, cardiovascular disease and stroke incidence were lower in the elderly with a history of cardiovascular disease. Healthcare professionals can use the results from this study to understand the benefits of multifactorial lifestyle interventions on cardiovascular disease. However, there is a need for longer-term robust studies since the evidence is sparse.
Abstract
AIMS: Joint prevention of cardiovascular disease (CVD) and dementia could reduce the burden of both conditions. The Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER) demonstrated a beneficial effect on cognition (primary outcome) and we assessed the effect of this lifestyle intervention on incident CVD (pre-specified secondary outcome). METHODS AND RESULTS FINGER enrolled 1259 individuals aged 60-77 years (ClinicalTrials.gov NCT01041989). They were randomized (1:1) to a 2-year multi-domain intervention with diet, physical and cognitive activity, and vascular monitoring (n = 631), or general health advice (n = 628). National registries provided data on CVD including stroke, transient ischaemic attack (TIA), or coronary heart event. During an average of 7.4 years, 229 participants (18%) had at least one CVD diagnosis: 107 in the intervention group and 122 in the control group. The incidence of cerebrovascular events was lower in the intervention than the control group: hazard ratio (HR) for combined stroke/TIA was 0.71 [95% confidence interval (CI): 0.51-0.99] after adjusting for background characteristics. Hazard ratio for coronary events was 0.84 (CI: 0.56-1.26) and total CVD events 0.80 (95% CI: 0.61-1.04). Among those with history of CVD (n = 145), the incidence of both total CVD events (HR: 0.50, 95% CI: 0.28-0.90) and stroke/TIA (HR: 0.40, 95% CI: 0.20-0.81) was lower in the intervention than the control group. CONCLUSION A 2-year multi-domain lifestyle intervention among older adults was effective in preventing cerebrovascular events and also total CVD events among those who had history of CVD.

Plain language summary
Lifestyle interventions are being increasingly recognised to delay or prevent the onset of dementia. Scientific research targeting one lifestyle factor has continually failed to show any benefits and therefore interventions targeting several lifestyle factors, before disease onset may be more beneficial. The Lifestyle for BRAin Health (LIBRA) score is a tool which assesses peoples risk of dementia based on several lifestyle factors and this trial used this tool to determine the dementia risk of individuals who entered The Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER). This study was the first randomised control trial showing benefits to cognition following multi-domain lifestyle interventions. The results showed that higher LIBRA score at the start of the trial was associated with poorer brain function over time and that the multi-domain lifestyle intervention was effective at decreasing LIBRA score, regardless of the risk at the start of the trial. It was concluded that LIBRA may be a useful tool to determine risk of dementia and that the FINGER intervention was of benefit to individuals regardless of their risk of dementia.
Abstract
INTRODUCTION Individuals in early dementia prevention trials may differ in how much they benefit from interventions depending on their initial risk level. Additionally, modifiable dementia risk scores might be used as surrogate/intermediate outcomes. METHODS In the Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER), we investigated in post hoc analyses (N = 1207) whether the cognitive benefits of the 2-year multi-domain lifestyle intervention differed by baseline dementia risk measured with the "LIfestyle for BRAin Health" (LIBRA) score. We also investigated intervention effects on change in LIBRA score over time. RESULTS Overall, higher baseline LIBRA was related to less cognitive improvement over time. This association did not differ between the intervention and control groups. The intervention was effective in decreasing LIBRA scores over time, regardless of baseline demographics or cognition. DISCUSSION The cognitive benefit of the FINGER intervention was similar across individuals with different LIBRA scores at baseline. Furthermore, LIBRA may be useful as a surrogate/intermediate endpoint and surveillance tool to monitor intervention success during trial execution.

Plain language summary
Early identification of individuals at-risk of dementia is essential for effective preventive strategies. The aim of this study was to investigate the effect of a multidomain lifestyle intervention on the risk of dementia. This study is a post-hoc analyses of intervention effects on change in the Cardiovascular Risk Factors, Aging and Dementia (CAIDE) Dementia Risk Score. The CAIDE score was used to select at-risk participants to the FINGER trial. FINGER is a multicentre study conducted in 6 centres in Finland. Results show a significant beneficial intervention effect, especially in women, on reducing estimated dementia risk measured by the CAIDE score. Authors conclude that CAIDE risk score can be used as a tool to communicate dementia risk, and to select persons that may benefit from lifestyle interventions.
Abstract
We investigated the effect of a multidomain lifestyle intervention on the risk of dementia estimated using the validated CAIDE risk score (post-hoc analysis). The Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER) is a 2-year randomized controlled trial among 1,260 at-risk older adults (60-77 years). Difference in the estimated mean change in CAIDE score at 2 years in the intervention compared to the control group was -0.16 (95 %CI -0.31 to 0.00) (p = 0.013), corresponding to a relative dementia risk reduction between 6.04-6.50%. This could be interpreted as a reflection of the prevention potential of the intervention.
