Tackling of unhealthy diets, physical inactivity, and obesity: health effects and cost-effectiveness.

The obesity epidemic is spreading to low-income and middle-income countries as a result of new dietary habits and sedentary ways of life, fuelling chronic diseases and premature mortality. In this report we present an assessment of public health strategies designed to tackle behavioural risk factors for chronic diseases that are closely linked with obesity, including aspects of diet and physical inactivity, in Brazil, China, India, Mexico, Russia, and South Africa. England was included for comparative purposes. Several population-based prevention policies can be expected to generate substantial health gains while entirely or largely paying for themselves through future reductions of health-care expenditures. These strategies include health information and communication strategies that improve population awareness about the benefits of healthy eating and physical activity; fiscal measures that increase the price of unhealthy food content or reduce the cost of healthy foods rich in fibre; and regulatory measures that improve nutritional information or restrict the marketing of unhealthy foods to children. A package of measures for the prevention of chronic diseases would deliver substantial health gains, with a very favourable cost-effectiveness profile.

The double burden of disease in developing countries: the Mexican experience.

OBJECTIVE: To present the challenges arising from the double burden of disease in developing countries, focusing on the case of Mexico, and to propose a strategy for addressing these challenges. METHODOLOGY/APPROACH: Mortality and morbidity data are presented for selected countries and groups of diseases. Specific examples of the pressures faced by the public health services in Mexico to provide and finance treatment for communicable and non-communicable diseases are used to illustrate the extent of the challenges in the context of a country with limited resources. FINDINGS: Public health systems in developing countries face strong pressure to provide and finance treatment for both communicable and non-communicable diseases, inevitably producing competition among diseases and conditions and requiring trade-offs between equity and efficiency goals. IMPLICATIONS FOR POLICY: In developing countries, addressing the challenges presented by the double burden of disease requires a multidisciplinary approach to develop and strengthen the policymaking process. This involves the use of analytical tools applied to each stage of the planning cycle, in particular the use of an explicit priority setting process together with monitoring and assessment to strengthen decision making under limited resources.
