| Abstract | |
This ecological study aimed to identify the risk areas for HIV/TB (Human Immunodeficiency Virus, HIV/tuberculosis) co-infection in the city of Ribeirão Preto, state of São Paulo, through the spatial distribution of the cases registered in 2006. The unit of observation was a set of individuals from Ribeirão Preto. The study population consisted of 48 new cases of HIV/TB co-infection, registered and of patients living in Ribeirão Preto in 2006. The information about co-infected TB patients was collected in the TB-WEB register system. Another source of information used was the database of the census sectors of the city, published by the Brazilian Institute for Geography and Statistics (IBGE) regarding the demographic census of the year 2000. Sociodemographic variables (gender, birth date, educational level and address) and clinical-epidemiological variables (type of case, clinical form, type of treatment, case closing and venue of care) were selected for patients\' characterization. To characterize the census sectors, variables related to the following topics were selected: average income of the individuals responsible for the households, average years of education of the individuals responsible for the households, average income of the women head of families, average years of education of the women head of families, proportion of illiterate people, proportion of illiterate women, percentage of households with 5 or more residents. The selected new coinfection cases were then georeferentiated using the ArcGIS 9.1 software, by Esri. The census sector was considered the spatial analysis unit and the statistical analysis was carried out with the main components. After the calculation of the socioeconomic factors, the responsible for the main variation (83%) was chosen, and it was entitled socioeconomic factor. The sectors remaining for analysis (633) were ordered decreasingly and divided into tertiles. Thus, the tertiles were classified in socioeconomic bands: upper (more favorable socioeconomic conditions), intermediate and lower (unfavorable socioeconomic conditions). In 2006, during the data collection period, 190 TB cases were registered in the TB-WEB, of which 58 (30.5%) were cases of co-infection. In this study, 48 new cases of co-infection were considered. The results showed that: 68.7% of the cases were of male subjects, aged between 20 and 39 years of age (47.9%), having studied between 4 to 7 years (58.3%), pulmonary clinical form (75%), under supervised treatment (48%), 48% had been cured and 31% were under treatment at HCFMRP-USP (Hospital das Clinicas of the University of São Paulo at Ribeirao Preto Medical School). The spatial distribution showed the concentration of the cases of coinfection in the West and North regions of the city (58.3%) and 52.1% of the cases were located in the lower socioeconomic band, followed by the intermediate band. The study evidenced a strong relation between the outcome of TB and social aspects among the cases of AIDS. The knowledge of certain social determinants and even the inequality that permeates a geographic space can favor a more appropriate planning of actions for the control of these diseases. (AU) | |
