Legal strategies to improve physical activity in populations.

Abstract

The World Health Assembly has adopted the World Health Organization’s (WHO) recommended target of achieving a 15% reduction in physical inactivity by 2030. The WHO Global Action Plan on Physical Activity provides a framework for countries to achieve this, using a systems-based approach to address the social and environmental determinants of physical inactivity. Lack of progress in many countries indicates a need to identify new ways of addressing this public health priority. WHO continues to highlight the importance of legislative and regulatory measures within the multicomponent and multisectoral action needed to reduce physical inactivity. Yet research into the role of law for addressing physical inactivity has been limited, in contrast to the legal approaches to other major noncommunicable disease risk factors such as smoking and alcohol use. Conceptual frameworks for public health law offer a method for mapping and understanding the determinants, mechanisms and outcomes of law-making for the promotion of physical activity within populations. We describe the development and application of a framework that aligns legal strategies with the WHO Global Plan policy objectives. This new framework – the Regulatory Approaches to Movement, Physical Activity, Recreation, Transport and Sport – can help policy-makers to use the untapped potential of legal interventions to support or strengthen a whole-system response for promoting physical activity. The framework illustrates the role of legal interventions to improve physical activity and identifies opportunities for research to advance understanding, implementation and evaluation of legal responses to this issue.
