Objectives: To estimate the healthcare costs of sarcopenia in the United States and to examine the effect that a reduced sarcopenia prevalence would have on healthcare expenditures.

Design: Cross-sectional surveys.

Setting: Nationally representative surveys using data from the U.S. Census, Third National Health and Nutrition Examination Survey, and National Medical Care and Utilization Expenditure Survey.

Participants: Representative samples of U.S. adults aged 60 and older.

Measurements: The healthcare costs of sarcopenia were estimated based on the effect of sarcopenia on increasing physical disability risk in older persons. In the first step, the healthcare cost of disability in older Americans was estimated from national surveys. In the second step, the proportion of the disability cost due to sarcopenia (population-attributable risk) was calculated to determine the healthcare costs of sarcopenia. These calculations relied upon previously published relative risk values for disability in sarcopenic individuals and sarcopenia prevalence rates in the older population.

Results: The estimated direct healthcare cost attributable to sarcopenia in the United States in 2000 was $18.5 billion ($10.8 billion in men, $7.7 billion in women), which represented about 1.5% of total healthcare expenditures for that year. A sensitivity analysis indicated that the costs could be as low as $11.8 billion and as high as $26.2 billion. The excess healthcare expenditures were $860 for every sarcopenic man and $933 for every sarcopenic woman. A 10% reduction in sarcopenia prevalence would result in savings of $1.1 billion (dollars adjusted to 2000 rate) per year in U.S. healthcare costs.

Conclusion: Sarcopenia imposes a significant but modifiable economic burden on government-reimbursed healthcare services in the United States. Because the number of older Americans is increasing, the economic costs of sarcopenia will escalate unless effective public health campaigns aimed at reducing the occurrence of sarcopenia are implemented.

Evidence-based intervention in physical activity: lessons from around the world

Promotion of physical activity is a priority for health agencies. We searched for reviews of physical activity interventions, published between 2000 and 2011, and identifi ed eff ective, promising, or emerging interventions from around the world. The informational approaches of community-wide and mass media campaigns, and short physical activity messages targeting key community sites are recommended. Behavioural and social approaches are eff ective, introducing social support for physical activity within communities and worksites, and school-based strategies that encompass physical education, classroom activities, after-school sports, and active transport. Recommended environmental and policy approaches include creation and improvement of access to places for physical activity with informational outreach activities, community-scale and street-scale urban design and land use, active transport policy and practices, and community-wide policies and planning. Thus, many approaches lead to acceptable increases in physical activity among people of various ages, and from diff erent social groups, countries, and communities.

Physical Activity 3 Evidence-based intervention in physical activity: lessons from around the world

Epidemiological, pathological, clinical, and experimental studies over the past 40 years convincingly show that physical inactivity and low physical fitness contribute substantially to the major chronic diseases prevalent in industrialised societies. Several industrialised countries around the world report increases in physical activity participation among adults in recent years, but the prevalence of inactivity remains high. These increases in voluntary exercise are at least partially offset by decreasing daily energy demands due to increased mechanisation at home, at work and during leisure-time. In developing countries, physical inactivity is becoming a prevalent lifestyle due to rapid social and economic changes. Clinical interventions and mass appeals to be more physically active are limited in effectiveness against the background of increasingly sedentary lifestyles. Exercise scientists and public health officials need to turn attention to public policy and legislative initiatives to restructure physical and social environments to encourage more physical activity and discourage sedentary habits.
