A Multifaceted Nutrition Intervention for Frailty in the Community Elderly

"In this group, a 3-month multifaceted nutrition intervention will be conducted. The specific content is as follows:~1. Anti-inflammatory dietary management: the elderly will receive an anti-inflammatory dietary menu designed based on the Chinese Dietary Guidelines for the Elderly (2022 Edition) provided by researchers.~2. Personalized nutritional intervention management: WeChat groups will be established to record the dietary status of the research subjects. The research subjects will be asked to keep a dietary diary and take photos of their diet daily. Trained researchers will record their daily diet and provide timely feedback to the research subjects.~3. Health education: Nutrition and health knowledge lecture will be held for elderly family caregivers and the elderly themselves every two weeks. The content will include basic knowledge of frailty, prevention and treatment guidance, health outcomes, medication management, and healthy behaviors."

To investigate the combined effects of nutrition and exercise, this group added exercise intervention in addition to the corresponding intervention measures of the nutrition intervention group. The subjects were required to exercise 3 times a week, 1 hour each time. The project included 10 minutes of warm-up exercises (stretching), 10-20 minutes of aerobic exercise (balance ability, leg and core muscle strength, etc.), 10-20 minutes of muscle resistance strength training (legs, buttocks, feet, upper limbs, etc.) and 10 minutes of relaxation training. All exercise programs were uniformly trained by professional coaches, and compliance was ensured by uploading photos to punch the clock. The intervention period is 3 months, with a follow-up of 9 months.

The control group will undergo routine community health management, including regular chronic disease health education lectures, provision of health education materials, health counseling services, and comprehensive health examinations by qualified medical professionals.
