Self-rated health has been used extensively in epidemiologic studies, not only due to its importance per se but also due to the validity established by its association with clinical conditions and with greater risk of subsequent morbidity and mortality. In this study, the socio-demographic determinants of good self-rated health are analyzed using data from the World Health Survey, adapted and carried out in Brazil in 2003. Logistic regression models were used, with age and sex as covariables, and educational level, a household assets index, and work-related indicators as measures of socioeconomic status. Besides the effects of sex and age, with consistently worst health perception among females and among the eldest, the results showed pronounced socioeconomic inequalities. After adjusting for age, among females the factors that contributed most to deterioration of health perception were incomplete education and material hardship; among males, besides material hardship, work related indicators (manual work, unemployment, work retirement or incapable to work) were also important determining factors. Among individuals with long-term illness or disability, the socioeconomic gradient persisted, although of smaller magnitude.

As taxas médias de incidência da AIDS em adultos no Brasil foram estimadas para os períodos 1987-89, 1990-92 e 1993-96, segundo o município de residência dos casos. Nas análises foram utilizadas as variáveis "tamanho da população do município de residência"; "proporção de população que vive em área urbana" e "concentração de pobreza", estratificando-se por sexo e categoria de exposição. A Região Sudeste apresenta menor ritmo de crescimento em contraste com os aclives acentuados das regiões Norte e Sul, do 2º ao 3º intervalo. Cotejando-se as variações das taxas de incidência de 1990-92 a 1993-96 por região ou tamanho de população, obtém-se maiores aumentos relativos entre as mulheres. Nas cidades grandes, a categoria "homo/bissexuais" prevalece, decrescendo proporcionalmente à medida que cresce o número de casos por transmissão heterossexual. Nos municípios médios predominam os usuários de drogas injetáveis e nos menores há aumento dos casos por transmissão heterossexual. A epidemia - ainda fenômeno urbano - dá sinais de expansão nos municípios rurais, intensificando-se naqueles situados abaixo do limite crítico regional do índice de pobreza. Há disseminação crescente da epidemia nos municípios mais pobres.

This ecological analysis addresses the association between income inequality and health status in the municipality of Rio de

Study objectives-To establish the geographical relation of health conditions to socioeconomic status in the city of Rio de Janeiro, Brazil. Design-All reported deaths in the municipality of Rio de Janeiro, from 1987 to 1995, obtained from the Mortality Information System, were considered in the study. The 24 "administrative regions" that compose the city were used as the geographical units. A geographical information system (GIS) was used to link mortality data and population census data, and allowed the authors to establish the geographical pattern of the health indicators considered in this study: "infant mortality rate"; "standardised mortality rate"; "life expectancy" and "homicide rate". Information on location of low income communities (slums) was also provided by the GIS. A varimax rotation principal component analysis combined information on socioeconomic conditions and provided a two dimension basis to assess contextual variation. Main results-The 24 administrative regions were aggregated into three diVerent clusters, identified as relevant to reflect the socioeconomic variation. Almost all health indicator thematic maps showed the same socioeconomic stratification pattern. The worst health situation was found in the cluster composed of the harbour area and northern vicinity, precisely in the sector where the highest concentration of slum residents are present. This sector of the city exhibited an extremely high homicide rate and a seven year lower life expectancy than the remainder of the city. The sector that concentrates aZuence, composed of the geographical units located along the coast, showed the best health situation. Intermediate health conditions were found in the west area, which also has poor living standards but low concentration of slums. Conclusions-The findings suggest that social and organisation characteristics of low income communities may have a relevant role in understanding health variations. Local health and other social programmes specifically targeting these communities are recommended. (J Epidemiol Community Health 2000;54:530-536) Throughout the history of epidemiology, different attributes of people and their environments have been considered as potential causes of disease. Socioeconomic status is one of the most consistently correlated factors of health conditions.

This study focuses on conditions in the public health centers providing comprehensive care to the adolescent population in the city of Rio de Janeiro. A structured questionnaire was administered to the coordinators of 70 public health centers (70/78). Based on the data, the public health centers were stratified according to basic conditions for providing full care to adolescents. The authors developed a spatial study of the demographic concentration and main problems, producing thematic maps. Of the 49 public health centers that participate in the Adolescent Health Program, 12% were classified in "good" condition and 45% were considered "fair". Among the administrative regions with the highest concentration of adolescents, only six (6/17) were in good or fair condition. The authors conclude that to increase the effectiveness of the city's Adolescent Health Program it is necessary to improve the working conditions of their health staff, taking local health problems, the concentration of adolescents, and their demands for services into account.
