Non-communicable diseases (NCDs), including coronary heart disease, stroke, hypertension, type 2 diabetes, dementia, depression and cancers, are on the rise worldwide and are often associated with a lack of physical activity (PA). Globally, the levels of PA among individuals are below WHO recommendations. A lack of PA can increase morbidity and mortality, worsen the quality of life and increase the economic burden on individuals and society. In response to this trend, numerous organisations came together under one umbrella in Hamburg, Germany, in April 2021 and signed the ‘Hamburg Declaration’. This represented an international commitment to take all necessary actions to increase PA and improve the health of individuals to entire communities. Individuals and organisations are working together as the ‘Global Alliance for the Promotion of Physical Activity’ to drive long-term individual and population-wide behaviour change by collaborating with all stakeholders in the community: active hospitals, physical activity specialists, community services and healthcare providers, all achieving sustainable health goals for their patients/clients. The ‘Hamburg Declaration’ calls on national and international policymakers to take concrete action to promote daily PA and exercise at a population level and in healthcare settings.

Objectives To identify how primary care physicians (PCPs) prescribe physical activity for patients with chronic disease, and to determine characteristics of physical activity interventions with improved clinical outcomes of chronic disease.Design A scoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews 2018 was completed.Data sources Four bibliographic databases (Medline, EMBASE, SPORTDiscus, CINAHL) and four grey literature/unpublished databases (Proquest, National Institute for Health and Care Excellence, Canadian Health Research Collections, Clinical Trials) were searched from inception to 7 March 2022.Eligibility criteria for selecting studies Studies involving PCP-delivered physical activity prescriptions or counselling for participants with a chronic disease or mental health condition, which reported clinical outcomes were included. Opinion papers, news and magazine articles and case reports were excluded, as were studies in which a physical activity intervention was provided for primary prevention of chronic disease, prescribed by healthcare providers or researchers other than PCPs, or for healthy participants without chronic disease.Results An initial search identified 4992 records. Fifteen studies met inclusion criteria. Characteristics of physical activity prescriptions that improved clinical outcomes included: personalised advice; brief intervention; behavioural supports (handouts and/or referrals) and physician follow-up. Reported adverse events were rare. Research gaps include optimal timing and length of follow-up, and the long-term and cost-effectiveness of interventions.Summary/Conclusion Several characteristics of physical activity counselling by PCPs for patients with chronic disease may improve clinical outcomes, although research gaps remain. Studies exploring the effectiveness of physical activity prescription for individuals with chronic conditions are urgently needed.
