Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Green Prescription (GrX) programme is designed to increase the uptake of physical activity among individuals with physically-limiting medical conditions. A script (GrX) prepared by general practitioners or practice nurses is faxed to Regional Sports Trust GrX teams to typically provide advice and support around increasing physical activity and improving nutrition. In this research the GrX is delivered by a GrX kaiwhakahaere/support person based at Sport Waikato. This person helps and supports the participant to set and achieve small achieveable goals with the GrX kaiwhakahaere through contact once a month for six months. The contact time is typically less than a hour.

Behaviour
Comparator / control treatment
Participants will be randomised within ethnicity and sex (Maori or European; male or female) to receive either the kanohi-ki-te-kanohi (face-to-face) or telephone intervention. At baseline, six month and one year measurements will be made. Effectiveness of each intervention will be measured by reported uptake of physical activity, fitness, reduction in waist circumference and weight loss as well as glucose homeostasis. The outcomes will be examined in terms of treatment, ethnicity and sex. Qualitative information will undergo thematic analysis and explore attitudes, behaviours and motivational factors to physical activity uptake by ethnicity and gender in the context of quantitative outcomes. Case studies and testimonials will be used to enrich the information and triangulate the findings.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation was concealed through central randomisation by computer of scripts through the GrX team administrator. This person is not responsibile for the delivery modes of GrX or any interaction with participants in this study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants are stratified to either kanohi-ki-te-kanohi or telephone intervention by gender and ethnicity (50% Maori and 50% New Zealand Europeans).
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?
