Park Prescription Trial

Details and patient eligibility


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.

Full 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.

Inclusion criteria

Subjects must meet all of the inclusion criteria as listed below to participate in the study.

Study participants must:

  • be not currently sufficiently active (less than 150 minutes per week of exercise);
  • complete and pass the PAR-Q+*;
  • have a blood pressure of less or equal to (<=) 139 mmHG (systolic) over less or equal to (<=) 89 mmHG (diastolic);
  • have fasting glucose levels of less or equal to (<=) 6.0 mmol/l);
  • be Singaporean or Permanent Residents;
  • be able to write and read;
  • provide informed consent.

Exclusion criteria

All subjects meeting any of the following exclusion criteria will be excluded from participation:

  • pregnant women;
  • people who have severe medical conditions prohibiting participation in physical activity as assessed by the PAR-Q (including, heart disease, lung disease, diabetes);
  • 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.

Parallel Assignment


None (Open label)

160 participants in 2 patient groups

Park prescription
Experimental group
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.
Behavioral: Park Prescription
No Intervention group
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.
