Tailored Education for Aging and Cognitive Health: A Health Behavior Change Intervention for Midlife Adults at Risk for Alzheimer's Disease and Related Dementias (TEACH)
Testing the Efficacy of a Personalized Multi-Domain Behavioral Intervention for Alzheimer's Disease and Related Dementias Risk Reduction in Midlife
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.

Gedetailleerde beschrijving
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).

Experimenteel: Experimental
TEACH Intervention |
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. |

Actieve vergelijker: Control
Basic Health Education |
The basic health education is an 8-week, remotely delivered group intervention that educates participants about 16 modifiable risk factors for ADRD. |

Tijdsspanne |
|---|---|---|
|
Multidomain behavioral composite
Tijdsspanne: baseline, 2 months (end of treatment), 4 months, 12 months
|
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). |
baseline, 2 months (end of treatment), 4 months, 12 months

Metabolic Syndrome Severity Score (MetS severity)
Tijdsspanne: baseline, 2 months (end of treatment), 4 months, 12 months
|
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 |
