NCT06225271

Brief Summary

The goal of this cohort-based cluster-randomized controlled trial is to investigate the effect of the combined intervention of exercise, fruit, and vitamin supplementation on frailty among older adults. Older individuals aged 65\~80 years old with low physical activity levels and low fruit intake will be recruited. 14 clusters will be randomized into 2 arms with 1:1 ratio. Participants in the intervention arm will receive the combined intervention of physical activity, fruit, and vitamin supplementation 3 times a week for 2 months (the 1st and 6th months). They will also be given group interventions, such as self-management group activity or health education, at least once a week. Participants in the control arm will not receive any intervention.

Outcome Measures

Primary Outcomes (1)

  • The change in handgrip strength at 12 months from baseline.

    Handgrip strength will be measured using a hand-held grip dynamometer. Participants will be asked to grip the dynamometer with left hand and right hand respectively while standing, maintaining their arm close to the body and straight down, exerting maximum force. This test will be conducted 3 times, and the values will be recorded in kilograms.

    Baseline and 12 months

Secondary Outcomes (13)

  • The change in handgrip strength at 6 months from baseline.

    Baseline and 6 months

  • The change in frailty index at 6 months and 12 months from baseline.

    Baseline, 6 months, and 12 months

  • The change in the quantity and frequency of fruit intake at 12 months from baseline.

    Baseline and 12 months

  • The change in physical activity volume and intensity at 12 months from baseline.

    Baseline and 12 months

  • The incidence of a composite of all-cause death, cardiovascular and cerebrovascular diseases over 12 and 24 months.

    12 months, and 24 months

  • +8 more secondary outcomes

Study Arms (2)

Intervention group

EXPERIMENTAL

Participants in the intervention group will receive group intervention and individual intervention. Group interventions will include participants' communication meeting and other approach, such as self-management group. They will also receive the combined intervention of physical activity, fruit, and vitamin supplementation 3 times a week for 2 months (the 1st and 6th months).

Behavioral: the combined intervention of exercise, fruit, and vitamin supplementation

Control group

NO INTERVENTION

Participants in the control arm will not receive any intervention.

Interventions

Group intervention After each intervention, investigators will hold a 15-minute communication and discussion session for the participants. Besides, community health workers will organize at least one health education activity per week during the intervention for no less than 45 minutes. Individual intervention Physical activity The participants will be gathered at the community activity center or day care center. The participants will be allowed to exercise in a way that interests them. The duration of exercise should be longer than 30 minutes. Fruit supplementation Consideration of seasonal supply situation and the participants' diabetic status, various types of fruit will be prepared. The fruit will be divided into 50g/100g servings. Participants will be required to eat on site. Vitamin supplementation During the intervention, the participants will be required to take 1 tablet of vitamin B complex plus 1 tablet of vitamin C every day.

Eligibility Criteria

Age65 Years - 80 Years
Sexall
Healthy VolunteersYes
Age GroupsOlder Adult (65+)

You may qualify if:

  • Permanent resident population aged 65\~80 years;
  • Able to walk independently indoors and outdoors;
  • Physical activity less than 1400 metabolic equivalent task (MET)-min/week and fruit intake less than 50 g/day;
  • Have not taken vitamin B and vitamin C supplementation in the past 3 months.

You may not qualify if:

  • Presence of a history of fracture;
  • Patients with severe impairment of renal or hepatic fuction. Severe hepatic impairment is defined as serum alanine aminotransferase and aspartate aminotransferase levels above 100 U/L, while severe renal impairment is defined as estimated glomerular filtration rate (eGFR) \< 45 mL/min, calculated according to the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations.
