Abstract (Summary)
The growing incidence of dengue in Brazil requires innovations to foster prevention of the proliferation of the disease?s vectors, particularly in household and their surroundings. Suchinnovations may involve the use of technologies associated with health information and education programs. Given the importance of dengue as a public health problem, variousactivities related to community information and education have been carried out in order to control the disease. However, the specific data on domiciliary dengue prevention do not showa direct relation between increase of knowledge and promotion of preventive behavior. The present study describes a method and the results of an educational intervention focusing ondengue prevention in student?s households. The intervention was applied to 8th and 9th grade students of a public school in an endemic area of Belo Horizonte, MG. The participants werestudents of four classrooms: two studying in the morning, one in the afternoon and the other in the evening. The study involved the manipulation of four experimental conditions of aneducational intervention which included three components: a lecture about dengue, the distribution of a net cover (saucernet), called evidengue (a preventive resource aimed atprotecting the water-collecting saucers of flowerpots), and a folder with information about the disease and the saucernet. Each condition was manipulated separately for each of the fourclasses. The experimental condition specified to each class was chosen by lot, in the absence of the researcher who gave the lecture about dengue. A sub-sample of 40 students (10 of eachclass) was selected for answering a questionnaire about dengue before and after the educational intervention, in order to evaluate the students? knowledge about the disease. Thequestionnaire included eight written questions of basic interest and related to three aspects of the knowledge about the disease: 1) the concept of dengue; 2) its way of transmission; and 3) its forms of prevention. Concluded the intervention in the school, field observers visited the households of 98 students (85.2% of the sample) and registered the adoption of evidengue saucernets. Adoption was defined as the verification by the observers of the proficient use of evidengue on one or more flowerpots in each of the visited households. The results related to the questionnaire replicate data from the literature, which shows good knowledge levels about dengue, especially about its prevention. Manipulation of the lecture component produced relative gains in knowledge about preventive actions and included a new concept in the students? verbal repertoire: the concept of sealing, in lieu of covering, a change that mayconfer greater precision regarding care taking actions with water collections containers in households. In all, considering the number of households in which flowerpots withsaucernetswere present, the intervention resulted in indexes of evidengueadoption of 34.8% in the first probe and 49,2% in the second. When thecontrol condition is excluded, the indexes were42.1% and 63% respectively. Manipulation of the folder component showed better adoption results than the other conditions of the study.
