Achieving the Framework Convention on Tobacco Control's potential by investing in national capacity.

May 2003 marked a critical achievement in efforts to stem the global tobacco epidemic, as the member states of the World Health Organization unanimously endorsed the Framework Convention on Tobacco Control (FCTC). However, the adoption of the FCTC signifies only the end of the beginning of effective global action to control tobacco. Over the next several years the utility of the FCTC process and the treaty itself will be tested as individual countries seek to ratify and implement the treaty's obligations.

Secondhand tobacco smoke in public places in Latin America, 2002-2003.

Context: The success of measures to restrict smoking in indoor environments and the intensity of enforcement vary among countries around the world. In 2001, the Pan American Health Organization (PAHO) launched the Smoke-Free Americas Initiative to build capacity to achieve smoke-free environments in Latin America and the Caribbean.

Objective: To assess secondhand smoke concentrations in public places in the capital cities of Argentina, Brazil, Chile, Costa Rica, Paraguay, Peru, and Uruguay in conjunction with the Smoke-Free Americas Initiative.

Evaluation of the American Stop Smoking Intervention Study (ASSIST): a report of outcomes.

Background: The National Cancer Institute funded an 8-year, nonrandomized demonstration project for tobacco prevention and control, the American Stop Smoking Intervention Study (ASSIST). To evaluate ASSIST, we compared changes in adult smoking prevalence, per capita cigarette consumption, and tobacco control policies between the 17 ASSIST states and the 33 non-ASSIST states and the District of Columbia.

Methods: The strength of tobacco control index was used to measure state-level program elements directed at tobacco control, and the initial outcomes index (IOI) was used to measure states' tobacco control policy outcomes.

Descriptive methods for evaluation of state-based intervention programs.

In this article, the authors discuss program evaluation of intervention studies when the outcome of interest is collected routinely at equally spaced intervals of time. They illustrate concepts using data from the American Stop Smoking Intervention Study, where the outcome is state per capita tobacco consumption. States differ widely in mean tobacco consumption, and these differences should be accounted for in the analysis.
