Approximately 25% of adults achieve <30 minutes of PA a week, and 80% of children under 15 years are not meeting current PA recommendations in the UK.5 The causes are multifactorial, including societal and political drivers. ST is a disease of public health and primary care importance, and primary care clinicians have a key role in educating and guiding individuals at both primary and secondary prevention levels. Unfortunately, recent evidence suggests that there is poor awareness of the availability and use of physical activity guidance in primary care.6Additionally, there is little current understanding as to what constitutes ‘being sedentary’ and of the mechanisms by which physical activity or inactivity impact on health and disease.Increasing our … ER -
