Study summary

This Stage II behavioral intervention development project will examine the efficacy of a multi-domain health behavior intervention for primary prevention of Alzheimer's disease and related dementias (ADRD) in middle age.

Read the detailed description

The 8-week, remotely-delivered TEACH intervention was designed to promote maintenance, not just initiation, of health behaviors that reduce risk for ADRD. This randomized controlled trial (N=140 per arm; 1:1 allocation) will examine the efficacy of TEACH versus basic health education alone at end of treatment (8 weeks) and 4- and 12-month follow-up. We will examine the efficacy of the intervention on a multidomain behavioral composite score and individual health behaviors related to dementia risk (Aim 1) and biological outcomes including metabolic syndrome severity and a proteomic dementia risk score (Aim 2). We will also examine behavioral mediators of treatment effects on biological outcomes (how the intervention works) and its possible moderators (who benefits the most; Aim 3).

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

Interventions

  • BehavioralTEACH

    The TEACH intervention provides a personalized assessment of and education about ADRD risk factors and health belief traits that are evidence-based moderators of behavior change. The 8-week, remotely delivered group intervention educates participants about 16 modifiable risk factors for ADRD. TEACH includes a personalized goal-setting process and education about health beliefs that are barriers or facilitators of behavior change.

  • BehavioralBasic health education

    The basic health education is an 8-week, remotely delivered group intervention that educates participants about 16 modifiable risk factors for ADRD.

What researchers measure

Primary outcomes

  1. Multidomain behavioral composite

    This multidomain behavioral composite score is an unweighted average of five individual health behaviors: physical activity, Mediterranean diet adherence, cognitive activity, sleep quality, and alcohol use. Z-scores (or robust z-scores based on median/median absolute deviation for non-normal variables) for each continuous component score at baseline are calculated. Individual measures include 7-day average of moderate/vigorous physical activity measured via wearable (physical activity, total sleep time), Mediterranean Diet Adherence Tool total score (diet), Florida Cognitive Activities Scale (cognitive activity), and average units of alcohol consumed in the past two weeks (alcohol).

    Time frame: baseline, 2 months (end of treatment), 4 months, 12 months

  2. Metabolic Syndrome Severity Score (MetS severity)

    Race- and sex-specific weighted z-score based on confirmatory factor analysis from NHANES data (Gurka et al., 2012, 2014). MetS severity score is based on waist circumference, blood pressure, triglycerides, HDL cholesterol, and fasting plasma glucose

    Time frame: baseline, 2 months (end of treatment), 4 months, 12 months

Timeline

1 registry update since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Feb 2027; primary completion for Feb 2031, 47 months later.

Of 882 non-industry interventional studies with no phase under Alzheimer Disease, half reached primary completion within 30 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 51. This study's planned 47 months is above that.

Counting every sponsor, half of 959 studies reached it within 29 months; a quarter within 15 and three quarters within 51.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
