The World Health Organization's Framework Convention on Tobacco Control: implications for global epidemics of food-related deaths and disease.

This paper reviews the major elements of the WHO Framework Convention on Tobacco Control and considers those that can be applied to diet and nutrition. Tobacco and food policy have important differences: the two commodities have distinctly different health impacts, and food companies may be more responsive to public concerns than the tobacco industry. Nevertheless, both food and tobacco policy address public health issues surrounding legal products. Both require comprehensive and multi-sector approaches at global and national levels. The degree of flexibility possible in interacting and partnering with the private sector and food and related industries and the related implications for regulations and laws are reasons for a more nuanced approach to diet and physical activity policy.

Estimates of global and regional smoking prevalence in 1995, by age and sex.

OBJECTIVES: We calculated regional and sex- and age-specific smoking prevalence estimates worldwide in 1995. METHODS: Sex-specific smoking prevalence data from studies in 139 countries and age distribution data from 7 studies were analyzed. RESULTS: Globally, 29% of persons aged 15 years or older were regular smokers in 1995. Four fifths of the world's 1.1 billion smokers lived in low- or middle-income countries. East Asian countries accounted for a disproportionately high percentage (38%) of the world's smokers. Males accounted for four fifths of all smokers, and prevalence among males and females was highest among those aged 30 to 49 years (34%). CONCLUSIONS: Future decades will see dramatic increases in tobacco-attributable deaths in low- and middle-income regions. Although much of this excess mortality can be prevented if smokers stop smoking, quitting remains rare in low- and middle-income countries.

Air travel and venous thromboembolism.

There has recently been increased publicity on the risk of venous thrombosis after long-haul flights. This paper reviews the evidence base related to the association between air travel and venous thromboembolism. The evidence consists only of case reports, clinical case-control studies and observational studies involving the use of intermediate end-points, or expert opinion. Some studies have suggested that there is no clear association, whereas others have indicated a strong relationship. On the whole it appears that there is probably a link between air travel and venous thrombosis. However, the link is likely to be weak, mainly affecting passengers with additional risk factors for venous thromboembolism. The available evidence is not adequate to allow quantification of the risk. There are insufficient scientific data on which to base specific recommendations for prevention, other than that leg exercise should be taken during travel. Further studies are urgently needed in order to identify prospectively the incidence of the condition and those at risk.
