Much remains to be understood about how low socioeconomic status (SES) increases cardiovascular disease and mortality risk. Data from the Kuopio Ischemic Heart Disease Risk Factor Study (1984-1993) were used to estimate the associations between acute myocardial infarction and income, all-cause mortality, and cardiovascular mortality in a population-based sample of 2,272 Finnish men, with adjustment for 23 biologic, behavioral, psychologic, and social risk factors. ⋯ In the lowest income quintile, adjustment for risk factors reduced the excess relative risk of all-cause mortality by 85%, that of cardiovascular mortality by 118%, and that of acute myocardial infarction by 45%. These data show how the association between SES and cardiovascular mortality and all-cause mortality is mediated by known risk factor pathways, but full "explanations" for these associations will need to encompass why these biologic, behavioral, psychologic, and social risk factors are differentially distributed by SES.

The incidence of new HIV infections in Asia and the Pacific will soon pass that in Africa and is projected to increase into the next century. The AIDS epidemic arising from these infections will have enormous consequences for the health and socioeconomic development of a region encompassing more than half the world's population.

Inexorably, the epicentre of the global HIV pandemic is moving from Africa to Asia. Despite many years of much-publicised analysis of the African epidemic, most countries in Asia and many in the Pacific have not introduced the public health strategies known to minimise the spread of HIV. What must be done now, and how can the developed countries in the region, such as Australia, assist their neighbours?

The objectives of this study were to evaluate the frequency and determinants of rectal bleeding and the association between rectal bleeding and risk of human immunodeficiency virus (HIV) infection among homosexual/ bisexual men in Mexico City. Men who requested anonymous HIV testing at a public clinic in Mexico City and who reported engaging in any homosexual behavior were eligible to participate in this study. Trained staff collected information on demographic factors, sexual behavior, psychological states, and HIV serostatus from all consenting, eligible clients. ⋯ Among men reporting sex with men in Mexico City, rectal bleeding is common. It is an independent risk factor for HIV infection, and warrants attention in acquired immunodeficiency syndrome prevention efforts. Rectal bleeding that results from rupture of anal warts may be an especially effective portal of HIV transmission.

Results of a 1995 survey reveal that 1,437 local health departments-half of those in the country-provide sexually transmitted disease (STD) services and receive about two million client visits each year. Their clients are predominantly individuals with incomes of less than 250% of the poverty level (83%), women (60%) and non-Hispanic whites or blacks (55% and 35%, respectively); 36% of clients are younger than 20, and 30% are aged 20-24. On average, 23% of clients tested for STDs have chlamydia, 13% have gonorrhea, 3% have early-stage syphilis, 18% have some other STD and 43% have no STD. ⋯ Some 14% offer services only in sessions dedicated to STD care, 37% always integrate STD and other services, such as family planning, in the same clinic sessions, and 49% offer both separate and integrated sessions. STD programs that integrate services with other health care typically cover nonmetropolitan areas, have small caseloads, serve mainly women and provide a variety of contraceptives. In contrast, those that offer services only in dedicated sessions generally are in metropolitan areas and have large caseloads; most of their clients are men, and few provide contraceptive methods other than the male condom.
