Effects of the Zinde Zihin Multidomain Lifestyle Program on Alzheimer's Disease Risk: A Two-Center Controlled Intervention Study
Effects of the Zinde Zihin Multidomain Lifestyle Program on Alzheimer's Disease Risk: A Two-Center Controlled Intervention Study
This study aims to evaluate the feasibility and implementation of the Zinde Zihin ("Fit Mind") multidomain lifestyle program for older adults aged 65 years and older living in public nursing homes. The program includes cognitive activities, physical exercises, nutrition education, psychosocial engagement, sleep education, and stress-management components delivered in eight structured sessions over four weeks. The primary objective is to examine changes in Alzheimer's Disease Risk Index-Short Form (ANU-ADRI-SF) scores from baseline to post-intervention. Secondary objectives include assessing changes in cognitive activity engagement and affect-related lifestyle factors.
The Zinde Zihin ("Fit Mind") Program is a multidomain lifestyle intervention designed to promote healthy cognitive aging among older adults. The intervention integrates cognitive training, physical activity, nutritional education, psychosocial engagement, and sleep/stress management techniques within a group-based framework. The program is delivered in eight structured sessions over four weeks, with each session lasting approximately 60-75 minutes.
Study Rationale Lifestyle factors such as cognitive stimulation, physical activity, sleep, and social engagement play an important role in cognitive health. Multidomain interventions involving these components may support healthy aging. This study was developed to examine the feasibility of such an intervention in Turkish nursing home settings.
Study Design This is an individually randomized, controlled pretest-posttest study conducted in two public nursing homes. Randomization is performed at the individual level after eligibility screening. The protocol follows CONSORT guidelines for individually randomized trials.
Participants Eligible participants are adults aged 65 years or older with a Mini-Mental State Examination (MMSE) score ≥23 who are able to communicate verbally and volunteer to participate. Exclusion criteria include diagnosed dementia, major psychiatric illness, severe sensory impairment preventing participation, or unwillingness to attend intervention sessions.
Intervention
Eight structured sessions are delivered to the intervention group:
The control group receives routine nursing home activities only.
Outcome Measures
Primary Outcome:
The Alzheimer's Disease Risk Index-Short Form (ANU-ADRI-SF), a self-report instrument assessing demographic, lifestyle, and medical factors associated with Alzheimer's disease risk. Scores are collected at baseline and at 4 weeks.
Secondary Outcomes:
Measures assessing cognitive activity participation and affect-related lifestyle factors, collected at baseline and 4 weeks.
Randomization and Allocation Concealment Participants are randomized using a computer-generated list stratified by institution. Allocation is concealed through sequentially numbered, opaque, sealed envelopes prepared by an independent researcher.
Blinding Due to the nature of the intervention, participants and facilitators cannot be blinded. Outcome assessors and data analysts remain blinded.
Ethics The study was approved by the Burdur Mehmet Akif Ersoy University Ethics Committee (GO 2025/1069). Written informed consent is obtained from all participants.
Data Collection and Timing Baseline and post-intervention assessments are administered individually by the researcher in a private room within the nursing homes.
Statistical Analysis Plan Descriptive statistics and statistical procedures appropriate to the data structure will be applied. Analyses will be conducted according to the predefined analysis plan.
