Targets to tackle the obesity epidemic: a review of twelve developed countries

Abstract

Objective: Health targets describe government intentions for improving population health. The present paper determines whether the targets which twelve developed countries have set for obesity match the seriousness of the public health problem. Design: Policy documents on general public health, obesity, nutrition and physical activity were obtained by repeated searches of government websites. Details of all relevant targets on overweight, obesity, nutrition and physical activity were extracted. Results: Only four of the countries studied have set targets for specific reductions in the prevalence of obesity. Two have targets that only mention reducing the prevalence of obesity and two other countries wish to halt the rise in prevalence. Two countries currently have targets which are much less ambitious than those in previous policies. No obesity targets are stated in the policies of four countries. Many of the countries studied have set detailed nutrition targets, but these seldom identify desired changes in dietary behaviour. No country has set targets for a reduction in energy intake. The physical activity targets reflect recommendations from the 1990s. Few targets are set for health knowledge or behavioural intentions which are prerequisites for desired lifestyle changes. Conclusions: Most of the countries studied have either set no targets or set very modest targets for reducing the prevalence of obesity. Many countries have physical activity targets that are likely to be insufficient to prevent obesity. Governments need to reconsider targets on obesity and to develop shorter-term targets which monitor desired lifestyle changes.

The longitudinal effect of body adiposity on joint mobility in young males with Haemophilia A

“…The finding that body adiposity exerts its effect on rate of mobility loss in lower limb joints but not in upper limb joints is compatible with the physiological role of lower limb joints as weight‐bearers. Our findings point to a very significant public health consequence as the prevalence of obesity in adults and youths has been rising in developed and in some developing countries [27–33]. Prior studies of the association between mobility and adiposity usually investigated the negative association of body adiposity with walking limitations, because of ease of measurement [8,16,30,34].…”

Prevalence of chronic diseases by immigrant status and disparities in chronic disease management in immigrants: a population-based cohort study, Valore Project

“…Access to health care (in the sense of the timely use of personal health care services to achieve the best health outcomes) is an essential prerequisite for ensuring good-quality health care and improving quality of life, and life expectancy [1]. From the perspectives of European integration and human rights, the health of migrants and their access to health care are important health policy issues [2,3].…”
