Associated factors to the intradomiciliary infestation of Aedes aegypti at Tambogrande district, Piura 2004

Abstract

Objectives: To determine the associated factors to the intradomiciliary infestation for Ae. aegypti in Tambogrande district, Piura (Northern Coastal of Peru). Material and methods: We conducted a case control study in the capital of district of Tambogrande, in December of the 2004. We regarded as housing-case (Hc) to the positive housing for Ae. aegypti infestation, and control housing (Ho) to the negative housing for Ae. aegypti infestation in at least a year with the following criteria, housing once was located in the district’s capital, according to the larval control register activities. For each case we considered two controls. We apply to the person in charge of the housing’s care that we included environmental, social and cultural factors in the questionnaire. Associates factors with p<0,10 value in the univariate analysis they were included in logistic regression model to estimate them OR adjusted and 95% confidence intervals (CI). Results: We poll 60 Vc and 124 Vo. The associated factors found in the multiple logistic model they went the presence of bottles in housing (OR: 7,66; CI: 2,95 – 19,84), household located at less than 200 m from a tire deposit (OR: 2,90; CI:1,13 – 7,48), household located at less than 200 m from a wood deposit (OR: 2,76; CI:1,14 – 6,66), and households with an inner garden (OR: 2.31; CI: 0,98 – 7,48) were statistically significant. We also identified that a household that has a maid (OR: 0,07; CI: 0,14 – 0,37) was a protective factor. Conclusions: The factors identified should be taken into account in the development of vector control programs in Tambogrande.
