Who cannot join
- All subjects meeting any of the following exclusion criteria will be excluded from participation:
- pregnant women;

- people who have a blood pressure of >139 mmHG (systolic) over >89 mmHG (diastolic);
- people who have fasting glucose levels of >6.0 mmol/l);
- those with physical disabilities or lower limb disorders.
- The Physical Activity Readiness Questionnaire (PAR-Q) is a self-guided, nine question screening tool that can quickly identify conditions or risk factors that require further assessment before engaging in physical activity. See: British Columbia Ministry of Health Department of National Health and Welfare: Physical Activity Readiness Questionnaire. Canada: 1992.For the current study, we are using an amended version of the PAR-Q.
- The PAR-Q+ also includes an additional section to formally assess subjects' age, whether they have physical disabilities or lower limb disorders, and their physical activity status.

About this study
The purpose of this study is to test the effectiveness of prescribing park use (i.e., ''Park Prescription'') to insufficiently active individuals. It is hypothesized that Park Prescription will motivate the target population to increase physical activity and thereby improve their physical and mental health.
Read the detailed description
BACKGROUND: There are substantial international research findings supporting the role that natural environments play in enhancing human health and the prevention of chronic diseases. Also, there is evidence highlighting the (cost-) effectiveness of prescribing physical activity to promote one's physical activity and health. However, there is a lack of methodologically rigorous studies that have looked into the effectiveness of combining these two promising approaches; i.e., physical activity prescription with a focus on the use of parks and green spaces: Park Prescription.
AIMS: This Randomized Controlled Trial (RCT) will investigate the concept of Park Prescription as a health promoting intervention for individuals. The primary objective is to investigate the effectiveness of a park prescription interventions to increase participant's time spent in moderate to vigorous physical activity (MVPA). Main secondary objectives are to assess; A) improvement in physical health (e.g., blood sugar and blood pressure) and health behaviour (e.g., sitting time); B) improvement in mental health (e.g., quality of life); 3) intervention implementation fidelity and the association with park use and perceived study participant satisfaction.
METHODOLOGY: Participants aged between 40 and 65 years will be recruited from the Singapore Population Health Community Screening Programme conducted by Alexandra Health Pte Ltd. They will be randomly assigned to one of the following two arms; 1) park prescription + participation in a weekly structured physical activity program conducted in the park, and 2) control group. Participants will be enrolled in the study for a period of 6 months. They will have to complete a baseline assessment, 3-month and 6-month follow-up. The investigators aim to recruit 80 participants in each arm, making a total of 160 study participants.

Park PrescriptionBehavioural
Please refer to the information included in the arm description.
| Study group | Role | What they receive |
|---|---|---|
| Park prescription | Experimental | The participants in this group will receive a brief counseling on physical activity together with a park prescription that highlights the importance of engaging in at least 150 minutes of physical activity per week and the possibility of engaging in physical activity in the park. In addition, they are invited to join in a structured and supervised physical activity program in the park. The structured physical activity program will take place in public parks located in the participants' neighbourhood. Participants will receive text messages for reminder and registration purposes approximately once a week. Also, participants will receive a sheet to monitor their weekly physical activity, information about parks in their neighborhood, and a counseling phone call half-way through the study. Receives: Behavioral: Park Prescription |
| Control | No intervention | The participants in this group will not be given any park prescription or be invited to participate in the weekly program in the park. However, they will receive all the information materials provided to the experimental group after the study has ended. |

Questions about this trial
What is this clinical trial studying?
A study testing Park Prescription in people with Healthy, run by National University of Singapore at 1 site in Singapore.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Hours/week spent in Moderate to Vigorous Physical Activity (MVPA) assessed objectively with accelerometry (time frame: At 6 months follow-up). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02615392, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jun 2017.
