- Influence of the social determinants on the incidence of aids in Piauí: an ecological studyPublication . Maranhão, Thatiana Araujo; Sousa, George Jó Bezerra; Alencar, Carlos Henrique; Magalhães, Mônica de Avelar Figueiredo Mafra; Abreu, Wilson; Pereira, Maria Lúcia DuarteObjective: to identify the social factors that determine the incidence of aids in the Piauí territory. Method: an ecological study that uses geoprocessing techniques in which 2,908 aids cases of individuals residing in Piauí were considered, notified to the Notifiable Disease Information System (Sistema de Informações de Agravos de Notificação, SINAN), from 2007 to 2015. Gross and Bayesian incidence rates were calculated using the population of the central year (2011), multiplied by 100,000 inhabitants, with Bayesian statistics used to identify spatial clusters. The non-spatial Ordinary Least Squares Estimation (OLS) and spatial Geographically Weighted Regression (GWR) regression models were used to identify the social determinants of the incidence of aids in the state, with 5% of significance. Results: the highest rates of the disease are concentrated in cities near the capital Teresina, with a Bayesian incidence of over 11.27 cases/100,000 inhabitants. The predictor variables of the incidence of ADIS in Piauí cities were the following: the percentage of individuals in houses with inadequate walls (p=0.0139), the mean number of residents per household (p=0.0309), and the percentage of individuals in households vulnerable to poverty and in which no one has completed elementary school (p=0.0051). Conclusion: according to GWR, the social factors that influence the incidence of aids in the cities of Piauí are the percentage of individuals in houses with inadequate walls, the mean number of residents per household, and the percentage of individuals in houses vulnerable to poverty and in which no one has completed elementary school. Given the above, interventions on the health social determinants of a structural nature should be established as effective methods for the prevention of HIV/ aids.
- Mortality due to acquired immunodeficiency syndrome and associated social factors: a spatial analysisPublication . Maranhão, Thatiana Araújo; Alencar, Carlos Henrique; Magalhães, Mônica de Avelar Figueiredo Mafra; Sousa, George Jó Bezerra; Ribeiro, Leonardo Miranda; Abreu, Wilson; Pereira, Maria Lúcia DuarteObjective: To analyze the spatial pattern of AIDS mortality and social factors associated with its occurrence. Methods: An ecological study that considered 955 AIDS deaths of residents in Piauí, reported in the Mortality Information System (MIS) from 2007 to 2015. Non-spatial and spatial regression models were used to identify social determinants of AIDS mortality, with a significance of 5%. Results: The predictors of AIDS mortality were illiteracy rate in males (p = 0.020), proportion of households with water supply (p = 0.015), percentage of people in households with inadequate walls (p = 0.022), percentage of people in households vulnerable to poverty and in whom no one has completed primary education (p = 0.000) and percentage of people in households vulnerable to poverty and dependent on the elderly (p = 0.009). Conclusion: Social indicators related to education, job and income generation and housing were associated with AIDS mortality.
- Space-Time pattern of aids mortalityPublication . Maranhão, Thatiana Araújo; Alencar, Carlos Henrique; Ribeiro, Leonardo Miranda; Sousa, George Jó Bezerra; Abreu, Wilson; Pereira, Maria Lúcia DuarteObjective: to analyze the spatial-temporal distribution of AIDS mortality. Method: this is a quantitative, descriptive study, which evaluated 959 aids deaths reported through the Mortality Information System. The temporal trend was analyzed using the Joinpoint Regression Program, version 4.6.0.0, and the Scan scanning was used to evaluate the formation of purely spatial clusters of deaths, considering a significance level of 5%. Results: most deaths occurred among males (71.1%), with seven years of schooling or less (79.6%), of pardo race (72.2%) and age group from 30 to 39 years (69.2%). There was a statistically significant increase in AIDS mortality of 5.2% per year (p<0.001; 95% CI: 1.0-9.5). The spatial scanning pointed to a statistically significant cluster of deaths (p<0.0001), which covered 18 municipalities, including Oeiras, Parnaíba and those in the metropolitan region of Teresina. Conclusion: the analysis of temporal and spatial trends showed a significant increased mortality over the period studied, as well as the presence of a cluster of deaths that covered 18 municipalities, including Teresina, Oeiras and Parnaíba.
