Según un estudio publicado en la revista médica británica The Lancet, la inactividad física tiene un coste anual global de 67,5 mil millones de dolares, es decir 61 mil millones de euros. Este importe se reparte en 49 mil millones de euros de gastos en sanidad y 12 mil millones de euros debido a pérdidas de productividad.
La inactividad física, comparada a una pandemia global, es una gran carga económica para todos los países del mundo. Para este estudio se han tenido en cuenta los gastos derivados de las cinco grandes enfermedades asociadas a la falta de actividad física: enfermedades coronarias, cardiovasculares, diabetes tipo 2, cáncer de pecho y cáncer de colon.
En España, el coste sanitario derivado de la inactividad física fue de 2,3 millones y medio de euros en 2013, siendo el país de la Unión Europea que más dinero pierde con esta carga social.
Summary
Background
The pandemic of physical inactivity is associated with a range of chronic diseases and early deaths. Despite the well documented disease burden, the economic burden of physical inactivity remains unquantified at the global level. A better understanding of the economic burden could help to inform resource prioritisation and motivate efforts to increase levels of physical activity worldwide.
Methods
Direct health-care costs, productivity losses, and disability-adjusted life-years (DALYs) attributable to physical inactivity were estimated with standardised methods and the best data available for 142 countries, representing 93·2% of the world’s population. Direct health-care costs and DALYs were estimated for coronary heart disease, stroke, type 2 diabetes, breast cancer, and colon cancer attributable to physical inactivity. Productivity losses were estimated with a friction cost approach for physical inactivity related mortality. Analyses were based on national physical inactivity prevalence from available countries, and adjusted population attributable fractions (PAFs) associated with physical inactivity for each disease outcome and all-cause mortality.
Findings
Conservatively estimated, physical inactivity cost health-care systems international $ (INT$) 53·8 billion worldwide in 2013, of which $31·2 billion was paid by the public sector, $12·9 billion by the private sector, and $9·7 billion by households. In addition, physical inactivity related deaths contribute to $13·7 billion in productivity losses, and physical inactivity was responsible for 13·4 million DALYs worldwide. High-income countries bear a larger proportion of economic burden (80·8% of health-care costs and 60·4% of indirect costs), whereas low-income and middle-income countries have a larger proportion of the disease burden (75·0% of DALYs). Sensitivity analyses based on less conservative assumptions led to much higher estimates.
Interpretation
In addition to morbidity and premature mortality, physical inactivity is responsible for a substantial economic burden. This paper provides further justification to prioritise promotion of regular physical activity worldwide as part of a comprehensive strategy to reduce non-communicable diseases
