Fatores associados à ocorrência de parasitoses intestinais em uma população de crianças e adolescentes

Abstract

Objectives: To analyze the prevalence and the factors associated with intestinal parasites infections in children and adolescents enrolled in elementary schools from São João del-Rei, Southeast Brazil.Methods: In this sectional study, coproscopic examinations were performed by spontaneous sedimentation and Kato-Katz techniques in 1,172 schoolchildren. Multivariate logistic regression models were adjusted for the study of factors associated with infections in general and separately for helminthes and protozoon.Results: The prevalence of infection was 29%, ranging from 7 to 83% between schools of lower and higher occurrence respectively. The presence of toilets in the home was associated with a lower prevalence of helminths; the increasing age of the students was associated with a higher rates of protozoon and parasites in general, while the presence of water filter and living in urban area were associated with a lower prevalence of the three outcomes. In all regions, the consumption of preventive medication against helminths was recorded. Conclusions:Inequalities in living conditions have changed the prevalence of parasitosis differently among the study regions. The study underscores the need to promote the use of water filters in endemic areas houses and to evaluate the preventive use of anti-helminthic drugs in the dynamic of individual health. Control measures that take into account the factors described should be a priority.Key-words: protozoan infections; helminths; /epidemiology; risk factors; health inequalities. RESUMOObjetivos: Analisar a prevalência de infecções por parasitos intestinais em crianças e adolescentes matriculados em escolas de ensino fundamental no município de São João del-Rei, Minas Gerais, e os fatores associados à infecção.Métodos Factors associated with intestinal parasites in a population of children and adolescents múltipla para o estudo dos fatores associados às infecções em geral e, separadamente, por helmintos e por protozoários.Resultados: A prevalência de infecções foi de 29%, havendo uma variação de 7 a 83%, respectivamente, entre as escolas de menor e maior ocorrência. A presença de instalação sanitária no domicílio foi associada a uma ocorrência menor de helmintos; o aumento na idade dos escolares associou-se a uma maior ocorrência de protozoários e de parasitos em geral; enquanto a presença de filtro de água e a localização do domicílio em área urbana mostraram-se associadas a uma ocorrência menor dos três desfechos analisados. Em todas as regiões, foi registrado o consumo de medicação preventiva contra helmintos.Conclusões: Desigualdades nas condições de vida tornaram as prevalências diferenciadas entre as regiões do estudo. O estudo ressalta a necessidade de promover o uso de filtros de água nas residências de áreas endêmicas e de avaliar o consumo preventivo de medicamentos anti-helmínticos na dinâmica e na saúde dos indivíduos. Medidas de controle que levem em conta os fatores descritos devem ser prioritárias em nível de Saúde Pública.Palavras-chave: infecções p...

Prevalence of Entamoeba histolytica and other enteral parasitic diseases in the metropolitan region of Belo Horizonte, Brazil. A cross-sectional study

“…This practice is rooted in popular culture in Brazil, regardless of the social or intellectual level of the population, and it has been reported in other studies. 12,25 Among the 13.5% of the infections caused by protozoa, Escherichia coli, Endolimax nana and Giardia lamblia were the most common species, in accordance with previous studies. 21,25 However, the rates of infection in our study were smaller, probably due to differences in the population included.…”

“…12,25 Among the 13.5% of the infections caused by protozoa, Escherichia coli, Endolimax nana and Giardia lamblia were the most common species, in accordance with previous studies. 21,25 However, the rates of infection in our study were smaller, probably due to differences in the population included. Only 4.2% of the protozoal infections were morphologically identified as Entamoeba histolytica or Entamoeba dispar.…”

Children's Environment in Brazil: From Domestic (Indoor) to Regional Threats

“…On the other hand, studies suggested that a reduction of the prevalence of the parasites infections was possible by the increase of sewage systems [73,88,89,91,92], the use of a water filter [70] and the household being in an urban area [96].…”

The Conjunction of Extension, Teaching and Research: the Experience of the Scientific Journey of Pharmacy and Biochemistry Students

“…Como consequências, podemos citar o comprometimento da qualidade de vida, e queda do rendimento laboral e escolar [4]. O saneamento básico também contribui de forma relevante para o controle da disseminação de doenças infecciosas [5].…”
