“…The direction and strength of the association between infection with G. duodenalis and standard of living was consistent with an earlier study in Salvador 21 ; however, in contrast to helminths, no significant positive association was observed between infection with G. duodenalis and standard of living. Almost 13% of preschoolers were infected with these waterborne protozoan parasites which often cause infectious diarrhea and gastroenteritis, in contrast to other studies Cad.…”

“…Furthermore, given the observational nature of our study, it is not possible to establish a causal association between growth indicators and intestinal parasitic infections. Finally, future studies should collect information on the presence of domestic animals in and around the home as this is also a risk factor for transmission of G. duodenalis 21 .…”

The objective of the present study was to characterize Giardia duodenalis infection among children living in sub-standard settlement areas in the municipality of Juiz de Fora, Minas Gerais State, Brazil. The cross-sectional epidemiological study included 590 children from 1 to 5 years of age. Data were collected from one child per selected family through home interviews with the parent or guardian and parasitological examination of stool samples. Thirty-one putative risk factors concerning family structure, socioeconomic status, and environmental factors were analyzed by multivariate logistic regression. Prevalence of G. duodenalis infection was 18% (106 children). Four potential risk factors were heavily associated with G. duodenalis infection: number of under-five children in the same household, index child's birth order, existence of a bathroom in the home, and drinking water source.

“…The existence of a toilet in the house was associated with fewer helminthic infections, as in the study conducted by Prado et al (31) . The helminth transmission mode, closely associated with ground contamination, may explain this finding.…”

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...
