Background and study aims
Reducing risk factors for dementia is increasingly important in light of its rising prevalence in the coming decades, particularly among lower socioeconomic status (SES) and migrant populations. The aim of this study is to evaluate the effectiveness and implementation of an mHealth lifestyle intervention to optimize brain health and reduce dementia risk factors through self-management with remote coaching.

Who can participate?
People aged 50-75 years who are of low socio-economic status and/or have a migration background (Turkish or South-Asian Surinamese), and have one or more dementia risk factors or cardiovascular (heart) disease

What does the study involve?
Participants are randomly allocated to a coach-supported, interactive app facilitating self-management of dementia risk factors (including hypertension, dyslipidemia, physical inactivity, smoking, and overweight) or to a control app with static health information. Blood pressure, total cholesterol, and BMI are measured, as well as the coverage, acceptability, adoption, appropriateness, feasibility, fidelity, and sustainability of the intervention, and dementia risk score, individual risk factors, and cost-effectiveness.

Where is the study run from?
Amsterdam UMC (Netherlands)

When is the study starting and how long is it expected to run for?
January 2023 to December 2026

Who is funding the study?
ZonMw (Netherlands)

Scientific titlemHealth Intervention for Dementia Prevention through lifestyle Optimisation (MIND-PRO): a hybrid effectiveness-implementation randomized controlled trial in middle-aged persons with low SES and/or migration background

Ethics approval(s)

Approved 30/01/2024, METC Amsterdam UMC (Meibergdreef 9, Amsterdam, 1105AZ, Netherlands; +31 (0)20 444 55 85; metc@vumc.nl), ref: 2023.0770

Health condition(s) or problem(s) studiedLowering dementia risk factors in people with elevated dementia risk
InterventionCurrent interventions as of 19/06/2024:
Randomization will take place in the app using a computer algorithm in a 1:1 manner. Participants will be informed that random allocation will be to one of two different smartphone apps and that the study is on improving lifestyle to reduce dementia risk factors. Partners who also participate in MIND-PRO will automatically be allocated to the same treatment arm, to avoid contamination.

The intervention is aimed at lifestyle behavioural change using a mHealth intervention (app), supported by a coach. Participants randomized to the intervention arm will have access to an interactive mobile app that facilitates self-management of dementia risk factors (hypertension, dyslipidaemia, active smoking, overweight, lack of physical exercise). After secure login, the app shows the participants’ dementia risk profile, based on baseline assessment. Participants can set goals for lifestyle change, monitor these goals, and enter self-measurements of for example weight, blood pressure and physical exercise. Furthermore, the app contains evidence-based education modules (both static and interactive), educational videos which will be developed within the project, and news items that are arranged according to personal risk factors. The participants will be supported by an experienced lifestyle coach trained in motivational interviewing who will be matched to the ethnicity of the participants as much as possible. The coaches will use motivational interviewing to help participants to formulate simple, measurable, achievable, realistic and time-bound (SMART) goals and guide the process to achieve the goals.

Participants randomized to the control condition will have access to an app which is similar in appearance but lacks any interactive features and does not provide coach support. It will contain general information on how to live a healthy lifestyle.

The intervention and follow-up are 12 months for the intervention and control group.

Primary outcome measureCurrent primary outcome measure as of 05/06/2024:

All effectiveness outcomes are measured at baseline and at the study end after 12 months.

1. The primary effectiveness outcome will be a composite score of the objectively measurable dementia risk factors:

Implementation outcomes:
Quantitative:

2.2. Adoption: quantitative analysis of the utilisation, usage and uptake, e.g. logins, goals setting, sending messages measured after 1 month (data features)
2.3. Appropriateness measured using a short questionnaire of perceived fit or relevance after 6 months and at study end
2.4. Acceptability measured using a short questionnaire of agreeability, user-friendliness, credibility, complexity, content* after 6 months and at study end
2.5. Sustainability: adherence, dropout measured after 6 months and at the end of the study, data features throughout the study
2.6. Implementation cost estimated by platform price and coach full-time equivalent at the end of the study

Qualitative:
2.7. Feasibility: the extent to which the mHealth intervention can be carried out, practical and social barriers/facilitators measured after 6 months
2.8. Appropriateness: perceived fit or relevance in the target population measured after 6 months
2.9. Acceptability: agreeability, user-friendliness, credibility, complexity, content measured after 6 months
2.10. Fidelity: the degree to which the mHealth application is implemented compared to the original protocol, measured after 6 months
