[The association between alcohol consumption and health services utilization].

The association between alcohol consumption patterns and the use of health services was examined in a cross-sectional survey of the general population of the Region of Madrid. Logistic regression analysis was used to determine the odds of moderate drinkers, excessive drinkers and non-drinkers to utilize health care services. Our findings indicate that moderate drinkers have a lower probability of utilizing health care services as compared to non-drinkers. Specifically, moderate drinkers showed a lower probability of utilizing both hospital (OR = 0.65 CI = 0.48-0.89) and ambulatory care (OR = 0.79 CI = 0.66-0.95) services. Furthermore, the frequency of use of ambulatory (OR = 0.79 CI = 0.64-0.95) and emergency care services (OR = 0.38 CI = 0.21-0.69) was also lower for moderate drinkers. Excessive drinkers also showed a tendency to use emergency care services less frequently (OR = 0.43 CI = 0.19-0.93). Both moderate and excessive drinking were also significantly associated with a shorter length of stay as compared to non-drinkers. The odds ratios are 0.41 (CI = 0.21-0.79) and 0.29 (CI = 0.19-0.39) respectively. Possible explanations of this "protective" effect of alcohol consumption, especially of moderate drinking, are discussed in relation to the diagnostic entities motivating the use of health care services.

Who won't tell: predictors of refusal to report number of sex partners.

Data from 1475 respondents to a telephone survey are used to examine whether those who refused to report the number of their sex partners in the 12-month period prior to the interview are more likely to engage in HIV risk behaviours than those who did report this number. Logistic regression shows that refusal is associated with being single of low education (OR(adj) = 8.0, 95% CI 2.7-23.7), using condoms in the last year (OR(adj) = 4.2, 95% CI 1.6-11.1), self-reporting of HIV-risk behaviours (OR(adj) = 3.6, 95% CI 1.3-9.6), and being male (OR(adj) = 2.7, 95% CI 1.1-6.6). These associations apply only to a subsample of individuals who provided complete information for HIV risk and other related behaviours. Results from the total sample indicate that individuals in our study who did not report their number of partners are more likely to have characteristics that are compatible with a higher probability of HIV risk practices. This pattern of associations suggests that refusers are indeed at higher risk for HIV infection than those sexually active individuals who did report the number of partners.

Role of drug injection in the spread of HIV in Argentina and Brazil.

Drug injectors' have become the second largest HIV transmission category in Argentina and Brazil, as is the case in many pattern I countries, making up more than one-quarter of all AIDS cases reported by 1991. HIV seroprevalence data suggest that the expanding proportion of AIDS cases attributable to drug injection stems from an absolute increase in the number of AIDS cases among drug injectors, and is not merely reflective of a decline in the proportion of cases reported in other transmission categories. Results of a review of studies in Argentina and Brazil indicate that HIV seroprevalence is increasing rapidly, contrary to the situation in some pattern I countries in which HIV seroprevalence among drug injectors is either stably high or increasing only slightly. Also contrary to most pattern I countries, cocaine rather than heroin is the injected drug of choice in Argentina and Brazil. Given that injectors of cocaine are more likely to be HIV infected than are heroin injectors, differences in the type of drug injected between countries may have distinct epidemiological consequences on the spread of HIV.

[Characteristics of sex behavior of men in Mexico City].

OBJECTIVE: To determine the major features of sexual behavior in men from Mexico City, such as the number of sexual partners, history of sexually transmitted disease (STD) and beliefs on AIDS. MATERIAL AND METHODS: A transversal epidemiologic study was conducted in 1995 based on multistage sampling with conglomerates. A total of 1,377 males from 15 to 49 years of age was interviewed by means of a structured questionnaire. Statistics such as Student's test and chi 2 were applied to determine significance. RESULTS: Subject mean age was 17.7 years (SD = 2.8 years) Overall proportion of condom use in the last intercourse was 24.6% depending on the type of partner: 18.8% used it with regular partners and 62.5% with multiple partners. Symptoms suggesting gonococcal uretritis were found in 2%. Finally, 97.5% understood the meaning of AIDS and knew some protective measures against infection. CONCLUSIONS: Some risky characteristics of sexual behavior were identified concerning the transmission of STD such as multiple sexual partners, not using condom and STD antecedents.

[Myths about the prevention and control of non-communicable diseases in Latin America].

Given the increase of the burden of non-communicable diseases (NCD) and the possibility to avoid it, it is urgent to implement or strengthen NCD preventive programs in Latin America. However, many myths hinder the implementation of NCD programs. Myths on NCD include: a) NCD are degenerative and incurable; b) they are diseases of the elderly; c) they are diseases of the rich. Like wise there are myths about NCD preventive programs are: a) difficult to implement, b) expensive, and c) ineffective. We present data that demonstrate how these myths are untrue and discuss the challenges to find a balanced health policy that emphasizes the importance of NCD without overlooking other diseases.

Opportunistic infections in pediatric HIV infection: a study of 74 autopsy cases from Latin America. The Latin American AIDS Pathology Study Group.

The present report describes opportunistic infections found at 74 autopsies of pediatric HIV/AIDS patients performed at several hospitals in Latin American countries. Fungal infections were the most common (53 cases), Candida sp. (39.18%) and Pneumocystis carinii (20.27%) being the most frequently recognized. Other fungal diseases included histoplasmosis, aspergillosis, and cryptococcosis. Viral infections were present in 31 cases, 38.7% being due to cytomegalovirus. Other viruses recognized included herpes simplex and adenovirus. Additional opportunistic infections were due to Mycobacterium avium-intracellulare, toxoplasmosis, and tuberculosis. Nonspecific bacterial bronchopneumonia was present in 11 cases. Cytomegalovirus and P. carinii coinfection was the most common association found. In this series patients died at a younger age (72% at or younger than 1 year old) and there was a slightly higher number of cases of histoplasmosis and brain toxoplasmosis than in other previously published series of infants and children.
