NCT Number: NCT06277583
The goal of the randomized controlled trials is to learn about the effects of urban farming interventions on older adults' physical, mental, and social well-being of older adults aged 50 to 85 years. The main questions the study aims to answer are Q1. Would participants who have undergone the urban care farming intervention have lower stress levels compared to those who did not undergo the intervention? Q2. Would the quality of life and biopsychosocial factors of older adults who participate in the urban farming interventions be better before the intervention and compared to those who did not participate? Q3. Would running intervention programs as such demonstrate cost-effectiveness? Participants will be enrolled in 24 weekly lessons providing hands-on urban farming techniques, including physical activity, planting, and social interactions. Researchers will compare older participants with similar demographic profile to determine if the biological, psychological, and social factors are better for the intervention group.

The data collection consists of three sessions, before and after the 24-week intervention program, and 6 months post-intervention. Prior to the data collection, participants will be assessed for eligibility criteria and explained the detailed study procedures by trained research staff for informed consent. After completing the written informed consent, participants will be interviewed using detailed questionnaires relating to their health, nutrition, and dietary status, psychosocial measures, and undergo a series of physical examinations. These examinations include physical performance tests of mobility and gait, balance and strength, body measurements of weight, height, body mass index (BMI), waist-hip circumference, mid-upper-arm and calf circumference, blood pressure, and blood tests that will examine participants' clinical profile, biomarkers, and immunoassays. Participants will also be given Fitbit trackers to determine if they have improved their physical activity. Last, data collected will also include Functional near-infrared spectroscopy (fNIRS), a non-invasive procedure to determine the oxygenation levels of participants at rest and while doing some thinking activities. This data collection procedure will be conducted at baseline before the intervention and after the completion of the intervention.
The intervention will include a weekly, 24-week urban farming program. Each weekly session is where participants will engage in outdoor and indoor horticultural activities ranging from fertilization, sowing, and watering, to transplanting, maintaining, and harvesting vegetables and herbs.

Inclusion criteria
Exclusion criteria
An intervention curriculum has been designed using horticulture therapy combined with urban farming techniques. The sessions will use plants and interaction with nature to engage and rehabilitate participants. Both the intervention and control group participants will undergo the intervention. But the intervention group will start with the urban care farming intervention first, and the control group will follow once the intervention group completes the program.
Time frame: Baseline, 6 months, 12 months
Brief version consisting of 26 QOL related questions developed by World Health Organisation. There are four domains, Physical, Psychological, Social relationships, and Environment. The minimum and maximum for each domain is 0 and 100 respectively, with higher scores being better outcome for each domain.
Time frame: Baseline, 6 months
changes in concentration of cytokines, chemokines and selected ageing and inflammatory markers in measured in pg/mL
Time frame: Baseline, 6 months, 12 months
8-items measuring the dimensions of needs fulfillment, group membership, influence, and emotional connection. Composite scores with the average of the 8 items is computed, min 1 and max. 8, with higher scores showing greater sense of community.
Time frame: Baseline, 6 months, 12 months
Fried frailty phenotype (FP) assesses physical frailty through five criteria: unintentional weight loss; weakness or poor handgrip strength; self-reported exhaustion; slow walking speed; and low physical activity. Total scores are classified into 3 categories: non-frail, pre-frail, and frail.
Time frame: Baseline, 6 months, 12 months
This scale measure of social engagement including family and friends, min score of 6 and max. score of 30. A higher score indicating more social engagement and a cutoff of 12 points indicate risk of social isolation.
Time frame: Baseline, 6 months
Brain oxygenation levels measured in cerebral metabolic rate of oxygen (CMRO^2).
Time frame: Baseline, 6 months, 12 months
EQ5D-5L, a measure that consists five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. An utility score can be attached to the total score to determine the cost utility of the participants' quality of life. An utility score between 0 to 1 on the Singapore population will be derived.
Time frame: Baseline, 6 months, 12 months
Participants are scored following MOCA scoring criteria. Max. 30 points. Scores lower than 26 showed signs of cognitive impairment.
Time frame: Baseline, 6 months, 12 months
Resilience scale on a 5 points scale, strongly disagree to strongly agree, the higher the score, the greater resilience.
Time frame: Baseline, 6 months, 12 months
Measures emotional and/or social loneliness situation of respondents and adds up to a total loneliness score. the total loneliness score can be categorized into four levels: not lonely (score 0, 1 or 2), moderate lonely (score 3 through 8), severe lonely (score 9 or 10), and very severe lonely (score 11).
Time frame: Continuous for 30 weeks

Attitude of healthy eating (11-items) adapted from Saba et al 2019 (DOI: 10.1016/j.foodqual.2018.11.017). Composite score computed from the averaged measures will have a min of 1 and max of 5.

Measured in systolic and diastolic
Time frame: Baseline, 6 months
A lipid panel measures levels of various types of lipids (fats) in the blood. Measures HDL cholesterol (High-Density Lipoprotein) and LDL cholesterol (Low-Density Lipoprotein) and Triglycerides
Time frame: Baseline, 6 months, 12 months
Behavior (8-items) towards eating fruits and vegetables developed for this study. Max. score of 10 and minimum score of 2 will be derived from this measurement.
