Sample size
Sample size was estimated using the Power Analysis and Sample Size (PASS) software (version 15.0.5) based on data from published research. Previous studies showed that the Cohens' d value was between 0.18~1.78. With these data, we estimated effect size of Cohen' d = 0.45, considering probabilities of 5% for type I error, 20% for type II error, and 0.05 for intraclass correlation coefficient (ICC). We randomized all 14 clusters (villages) into two arms with 1:1 ratio, and the total sample size was calculated to be 700 (50 participates per cluster). A conservative estimate of 25% loss to follow-up or drop-out indicates a total of 934 participates is needed.
Statistical analysis
Categorical variables are presented as frequencies (n) and percentages (%). Continuous data is reported as means and standard deviation (SD) or medians (interquartile range) for non-normality of distribution.
The primary analysis will compare the change in handgrip strength at 12 months from baseline between the intervention and control groups using the cluster-adjusted generalized linear mixed model (GLMM). The primary analyses will be intention-to-treat.
Secondary analyses:
- Compare the change in handgrip strength at 6 months from baseline between the intervention and control groups using the cluster-adjusted GLMM.
- Compare the change in frailty scale at 6 months and 12 months from baseline between the control and intervention groups using the cluster-adjusted GLMM.
- Compare the change in physical activity volume and intensity and fruit intake and frequency at 12 months from baseline. This will be achieved by comparing the least square mean between groups.
- Compared the incidence of a composite of all-cause death, cardiovascular and cerebrovascular diseases using Poisson regression model.
- Compare the incidence of all-cause death using Poisson regression model.
- Compare the incidence of cardiovascular and cerebrovascular using Poisson regression model.
- Compared the change in lipid indicators at 12 months and 24 months from baseline between the intervention and control groups using the cluster-adjusted GLMM.
- Compared the change in glucose indicators at 12 months and 24 months from baseline between the intervention and control groups using the cluster-adjusted GLMM.
- Incremental cost-effectiveness ratio (ICER). The outcome defined as the excess cost of a strategy over the cost of the baseline strategy divided by the incremental difference in effectiveness between the strategy in question and the baseline strategy.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Intervention group
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).
|
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. |
No Intervention: Control group
Participants in the control arm will not receive any intervention.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The change in handgrip strength at 12 months from baseline.
Time Frame: Baseline and 12 months
|
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.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The change in handgrip strength at 6 months from baseline.
Time Frame: Baseline and 6 months
|
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 6 months
|
The change in frailty index at 6 months and 12 months from baseline.
Time Frame: Baseline, 6 months, and 12 months
|
Outcome is defined as the change in the score of modifiable variables in the frailty index from baseline.
The frailty index consisted 28 variables covering age, physical measurement, sleep quality, history of surgery, fall, and fracture, history of the disease, oral hygiene, respiratory function, and physical function self-assessment aspects.
24 of the 28 variables can be changed.
The frailty index is a continuous variable that ranged from 0 to 33, with a higher value indicating a worse, frailer status.
|
Baseline, 6 months, and 12 months
|
The change in the quantity and frequency of fruit intake at 12 months from baseline.
Time Frame: Baseline and 12 months
|
Fruit intake will be collected by questionnaire for the frequency of consumption and weights per intake.
The frequency will be determined by filling in the number of times the participants eat fruit per week/day/monthly/year.
Fruit quantity is determined by the product of frequency and weights of a single fruit intake.
|
Baseline and 12 months
|
The change in physical activity volume and intensity at 12 months from baseline.
Time Frame: Baseline and 12 months
|
Information on physical activity levels during the past week will be collected through the International Physical Activity Questionnaire Scale-Short Form (IPAQ-SF).
The IPAQ-SF captures four levels of physical activity intensity: vigorous-intensity physical activity, moderate-intensity physical activity, walking time, and average sitting time on weekdays, including sedentary work.
Physical activity volume will be determined by summing the metabolic equivalent task (MET)-min/week values for walking, moderate physical activity, and vigorous physical activity.
Higher values represent higher levels of physical activity, with a minimum value of 0.
