Large-scale problems require large-scale solutions. Tackling the ‘Big 4’ behaviours (physical inactivity, tobacco use, excessive consumption of food and alcohol) requires scalable interventions that can reach large numbers of people to achieve a significant public health impact. One promising approach is to use brief interventions delivered by practitioners in healthcare settings. For example, in the UK, the National Institute for Health and Care Excellence recommends that primary care practitioners deliver tailored, ‘brief’ physical activity advice to inactive adults, and follow this up at subsequent appointments.
