Urban prevalence of epilepsy: a study of the population of São José do Rio Preto- Brazil

Abstract

Introduction. The purpose of this study was to survey the prevalence of epilepsy in the urban population of São José do Rio Preto, a medium-sized city, 360,000 inhabitants, at northwest of São Paulo state, Brazil.Method: This population cross-sectional epidemiological study was carried out into two stages. The first was to access validation of the screening questionnaire on a neighborhood of the city; the second was the study of the prevalence in a randomly, stratified large-scale survey on the population of the city. A gold standard protocol, clinical history and neurological examination, was used to diagnose all the positive cases. The false negative cases were obtained after the validation of results by a mathematical model. For assessing prevalence Chi-square test and Confidence Interval (CI 95%) were used to analyze the results (p-value ≤ 0.05).Results: The Validation of the screening questionnaire showed a sensitivity of 95.83% and a specificity of 97.8%. There were 17,293 individuals in the studied sample; the distribution according to sex, age group and race was similar to the general population. Lifetime crude prevalence of epilepsy was 18.6/1000 inh. (CI 95%;16.6-20.6); 8.2(CI 95%;6.8-9.5) for active and

Oral and maxillofacial trauma in patients with epilepsy: prospective study based on an outpatient population

“…Epilepsy in adults is independent of gender, as also reported by Borges et al 3 Most of the study partic- ipants were in the adult age range, in which the risk of accidents between the two groups is similar.…”

“…In the city of São José do Rio Preto, according to a study by Borges et al 3 , the prevalence of epilepsy is estimated to be 18.6 per 1000 inhabitants and is closely associated with individuals' social class. Using the same methodology in the cities of São José do Rio Preto and Campinas, these authors subsequently confirmed this estimate 4 .…”

Prevalence of seizures and associated factors in children under five living in a deprived municipality of southern Brazil

“…this high estimate is consistent with the findings of other studies conducted in other underdeveloped countries 3,4 . concerning studies conducted in brazil 7 , approaching a group of the same age rate, a prevalence of 4.9/1000 was found in rio Preto, a prosperous city of são Paulo state 10 . this number is close to the values found in developed countries, but it is ten times lower than the number found in this study.…”

“…In rio de Janeiro city, another study found an accumulated prevalence of 16.3/1000 cases 9 . In são José do rio Preto, são Paulo state 10 , a study of prevalence in the urban population was conducted and an accumulated prevalence of 18.6/1000 inhabitants, and 8.2/1000 for active epilepsy was found over the past two years. the purpose of this study was to identify the prevalence of seisure in children under five years old in the town of são José do Norte (rio Grande do sul state, brazil), as well as to establish possible associations among socio-economic and children health variables with this neurological disorder.…”
