AIDS. 2008 Jul; 22 Suppl 1:S51-7.Because full funding for HIV/AIDS prevention interventions is unlikely to occur in the near future, it is essential that the resources available are spent in the most effective way possible. This paper presents a matrix of effectiveness coefficients for HIV/AIDS-related prevention interventions that can be used as an integral part of the coordinated strategic planning process currently underway by the World Bank and UNAIDS, as the interventions in the matrix are harmonized with the interventions in that process. Coefficients for four types of sexual behavior change (condom use, partner reduction, sexually transmitted infection treatment-seeking behavior, age at first sex) across three different risk groups (high, medium, low) are presented, along with their interquartile ranges. Results indicate that: (1) impacts seem greater when an intervention includes interpersonal contact, rather than targeting a more general audience; (2) although significant impacts are observed in the columns measuring changing condom use, other impacts are lower, and sometimes are actually (measured) zero; and (3) additional studies have evaluations of the number of sexual partners and have found a greater impact than previous studies. Although progress has been made in increasing the number of evaluation studies that can be utilized in this impact matrix, particularly in the area of youth interventions, there are still empty cells in which no studies report impacts. Finally, it is important to note that issues such as quality differences and synergies between programmes could have an effect on the impacts calculated for a particular strategic plan.
MMWR. Morbidity and Mortality Weekly Report. 2008 May 23; 57(20):545-549.Tobacco use is one of the major preventable causes of premature death and disease in the world. The World Health Organization (WHO) attributes approximately 5 million deaths per year to tobacco use, a number expected to exceed 8 million per year by 2030. In 1999, the Global Youth Tobacco Survey (GYTS) was initiated by WHO, CDC, and the Canadian Public Health Association to monitor tobacco use, attitudes about tobacco use, and exposure to secondhand smoke (SHS) among students aged 13-15 years. Since 1999, the survey has been completed by approximately 2 million students in 151 countries. A key goal of GYTS is for countries to repeat the survey every 4 years. This report summarizes results from GYTS conducted in Sri Lanka in 1999, 2003, and 2007. The findings indicated that during 1999-2007, the percentage of students aged 13-15 years who reported current cigarette smoking decreased, from 4.0% in 1999 to 1.2% in 2007. During this period, the percentage of never smokers in this age group likely to initiate smoking also decreased, from 5.1% in 1999 to 3.7% in 2007. Future declines in tobacco use in Sri Lanka will be enhanced through development and implementation of new tobacco-control measures and strengthening of existing measures that encourage smokers to quit, eliminate exposure to SHS, and encourage persons not to initiate tobacco use.

Anti-tuberculosis drug resistance in the world. Fourth global report. The WHO / IUATLD Global Project on Anti-Tuberculosis Drug Resistance Surveillance, 2002-2007.
Geneva, Switzerland, World Health Organization [WHO], 2008.  p. (WHO/HTM/TB/2008.394)This is the fourth report of the WHO/IUATLD Global Project on Anti-Tuberculosis Drug Resistance Surveillance. The three previous reports were published in 1997, 2000 and 2004 and included data from 35, 58 and 77 countries, respectively. This report includes drug susceptibility test (DST) results from 91,577 patients from 93 settings in 81 countries and 2 Special Administrative Regions (SARs) of China collected between 2002 and 2006, and representing over 35% of the global total of notified new smear-positive TB cases. It includes data from 33 countries that have never previously reported. New data are available from the following high TB burden countries: India, China, Russian Federation, Indonesia, Ethiopia, Philippines, Viet Nam, Tanzania, Thailand, and Myanmar. Between 1994 and 2007 a total of 138 settings in 114 countries and 2 SARs of China had reported data to the Global Project. Trend data (three or more data points) are available from 48 countries. The majority of trend data are reported from low TB prevalence settings; however this report includes data from three Baltic countries and 2 Russian Oblasts. Trend data were also available from 6 countries conducting periodic or sentinel surveys (Cuba, Republic of Korea, Nepal, Peru, Thailand, and Uruguay). (excerpt)
