Abstract text Introduction New Zealand Green Prescription (GRx), a physical activity (PA) counselling programme, has been shown to increase short and long-term PA levels, and to improve perceived health benefits in sedentary individuals (Elley, et al., 2003; Lawton et al., 2009; Sinclair & Hamlin, 2007; Swinburn et al, 1998). The purpose of this study was to compare the short and long-term effects of the Be Active (BA) and Telephone Support (TS) versions of the GRx programme on physical activity and wellbeing. Methods Forty eight previously sedentary adults (mean 54.4 yrs, 68.8% females) referred to the GRx programme volunteered for the two group repeated measures intervention study. Following a face-to-face consultation, participants opted to take part in either a 10 week BA programme (1.5h weekly session of combined PA and education) (n = 28) or TS (15-20 min phone consultation every 4-6 wks for 4 months) (n = 20). Testing of the outcome measures – physical activity, % body fat, BMI, waist and hip circumferences, blood pressure, submaximal exercise efficiency, self-reported wellbeing – was carried out at baseline, 10 weeks, 6 months and 12 months. Outcome measures across these four time points were analysed using repeated measures ANCOVA modelling. Results Physical activity increases were significantly greater following the BA programme compared with the TS (p = 0.011), a behavioural change which was maintained at 12 months. Subsequently, body composition was improved over time with a decrease in body mass, BMI and waist circumference, adaptations which were sustained long-term. This improved body composition was greater in those exceeding the participation threshold (body mass p = 0.018, BMI p = 0.029) or those of a lower SES (BMI p = 0.046, waist circumference p = 0.006). More deprived individuals also had greater improvements in self-perceived general health (p = 0.012). Discussion These findings support the increase in short (Swinburn et al., 1998) and long-term (Elley et al., 2003) activity levels previously found following traditional GRx support and extends these findings, showing the Canterbury Be Active programme to increase physical activity levels to a greater extent. A lack of change in clinical outcomes has previously been reported (Elley et al., 2003; Swinburn et al., 1998), however, the current findings suggest improvements may be dependent on being provided with a minimal level of support and socio-economic status.
