Physical activity plays an integral role in management of Type 2 diabetes. Despite strong evidence, a limited number of physical activity interventions have been implemented within routine diabetes care. The aim of this research is to explore the practical issues related to translation, implementation and evaluation of physical activity interventions delivered in everyday settings. Chapters 1-2 introduce the topic and presents the current literature. Chapter 3 presents a systematic review of physical activity interventions delivered within everyday practice. Findings from 12 articles demonstrate that although 66.7% of interventions (n=8) reported an increase in physical activity levels, few publications reported information on intervention translation and implementation. Chapter 4 uses qualitative interviews and an online survey to explore the insight of health professionals on physical activity promotion within routine care. Findings conclude that physical activity promotion could be improved by: (1) having a key member of staff responsible for physical activity promotion, (2) a referral route for physical activity support, (3) behaviour change training for staff, (4) linking delivery of physical activity with clinical outcomes, and (5) using 'champions' to raise the profile of physical activity within the health service. Chapter 5 presents findings from a process evaluation of a physical activity consultation intervention delivered within routine diabetes care. Results show that an evidence-based protocol can effectively promote physical activity and improve health outcomes in adults with diabetes. Several practical issues were identified including the need for flexibility in the intervention protocol and the role of 'champions' to promote adoption of the intervention. Chapter 6 collates findings from each study to provide recommendations on translation, implementation and evaluation of physical activity interventions within routine diabetes care. This thesis demonstrates that delivery of physical activity interventions within routine diabetes care is challenging and complex. The recommendations should guide and support this process.
