Impacto da infecção chagásica sobre algumas características demográficas: resultados de um estudo ecológico

Abstract

In the endemic areas, similar infection rates were observed in males and females. However, males, mainly those aged 30 or more, had higher mortality rates than females. Analyses were conducted on a set of secondary data from several different sources. They included prevalence of T. cruzi infection, specific mortality related to Chagas' disease, and demographic characteristics. The data were aggregated at two different levels: municipality and homogeneous micro-regions. Significant positive correlations were observed between prevalence of T. cruzi infection and mortality rates. These indicators, in turn, were correlated with the proportion of widows and widowers in the population. Findings were higher for widows. In areas where prevalence of T. cruzi infection was 15% or greater, there were 22% more widows as compared to infection free areas. Places with high prevalence presented some skew in the age structure, and there was a consistent decrease in the proportion of males in the 35-44 age group. A possible confounding effect of migration on these finding was not demonstrated.

Associação entre hanseníase e infecção pelo vírus da hepatite B: estudo de caso-controle

“…Se a diferença observada na "incidência" e forma clínica entre sexo reflete diferenças na exposição, na suscetibilidade, na gravidade da doença não parece bem determinado. Diferenciais entre sexo na prevalência de infecção na população e na morbi-mortalidade são fenômenos encontrados com freqüência na epidemiologia de outras doenças infecciosas (Andrade et ai., 1992;Barreto & Andrade, 1994 (Albuquerque et al, 1989;Quaresma et al, 1989;Cestari et al, 1989;Andrade, 1990 . * * *** *** ********* 10+********************************************* ----+----+----+----+----+----+----+----+----+ …”
