Improving Dietary Quality and Social Engagement Through a Virtual Nutrition and Teaching Kitchen Intervention Among Older Veterans With Impaired Mobility
What this study is about
Compared to non-Veterans, Veterans demonstrate an increased risk for obesity and multimorbidity. Thus, interventions to improve overall health are warranted in this population.
View original scientific description
Compared to non-Veterans, Veterans demonstrate an increased risk for obesity and multimorbidity. Thus, interventions to improve overall health are warranted in this population. Healthy diets that include fruits and vegetables are linked to a reduced risk of chronic disease including mobility disability, and are associated with higher muscle mass, strength and physical performance potentially slowing further disability progression later in life. The investigators will determine if a three-month virtual group nutrition intervention paired with produce delivery and virtual teaching kitchen cooking demonstrations tailored for older Veterans with impaired mobility will improve diet, health-related quality of life and muscle strength.
Interventions
BEHAVIORAL
Nutrition Intervention
Weekly virtual live group sessions led by a trained study team member will be held twice weekly for 1 hour/week over 12 weeks using a HIPAA compliant online platform. The first class of each week will include the teaching kitchen cooking demonstration (\~30 min) and the remainder of the class will focus on dietary education. The second class each week will provide an opportunity for group discussion to have Veterans share to their peers about how they used the weekly produce
BEHAVIORAL
Contact Control
Weekly virtual live group health education sessions led by staff will be held for two hours/week over 12 weeks. We will enroll up to 15 participants into each virtual class cohort and run multiple different group sessions for a total sample size of 90 participants. The content follows the LIFE study structured successful aging health education curriculum80,81 which was designed to increase self-efficacy and empower older Veterans to take control of their own healthcare. Topics focus on a broad range of healthy aging, such as importance of sleep, safe travel, goal setting, self-care, and common comorbidities
Primary outcome measures
Diet quality
Time frame: 3 month and 6 month compared to baseline
Habitual dietary intake will be assessed using three 24-h recalls via the online Automated Self-Administered 24-hour (ASA24) Dietary Assessment Tool, version (2022), developed by the National Cancer Institute, Bethesda, MD. The dietary recalls will be used to calculate diet quality using the HEI; scores range from 0 to 100; higher scores indicate better adherence to the Dietary Guidelines for Americans.
Social Isolation
Time frame: 3 month and 6 month compared to baseline
The Lubben Social Network Scale, is a 12-item scale to assess self-reported social engagement including family and friends (Cronbach's =0.70). The total score is calculated by finding the sum of the all items. The score ranges between 0 and 60, with a higher score indicating more social engagement. The UCLA Loneliness Scale is a 20-item scale to measure subjective feelings of loneliness \& social isolation (Cronbach's 0.89\<0.94). Using a 4-point rating scale (1= never; 4 = always), participants answer 20 questions, such as "How often do you feel left out?" and "How often do you feel part of a group of friends?" Researchers later reverse-code the positively worded items so that high values mean more loneliness, and then calculate a score for each respondent by averaging their ratings. Both measures are included because they assess complementary but separate constructs

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
