[Local conditions of vulnerability associated with dengue in two communities of Morelos]. / Condiciones locales de vulnerabilidad asociadas con dengue en dos comunidades de Morelos.

OBJECTIVE: To evaluate the vulnerability associated with the occurrence of dengue in two villages of Morelos, Mexico from 2006 to 2009. MATERIALS AND METHODS. A survey on knowledge, risk perception, prevention practices and water use was applied in two villages of Morelos. Using a principal component analysis, an index of local vulnerability to dengue (IVL) was constructed. The association of IVL with the disease at home was assessed using a Chi-square test. RESULTS: The IVL included five components explaining 63% of the variance and was classified in three categories: low, medium and high. There was a significant association between increased vulnerability and prevalence of reported cases of dengue in Temixco and Tlaquiltenango. CONCLUSION: The study of vulnerability to dengue allows us to identify local needs in the field of health promotion.

OBJETIVO: Evaluar las condiciones de vulnerabilidad asociadas con la ocurrencia de dengue en dos localidades de Morelos en los años 2006 a 2009. MATERIAL Y MÉTODOS: se aplicó una encuesta sobre conocimientos, percepción de riesgo, prácticas de prevención y uso del agua en dos localidades de Morelos. Mediante un análisis de componentes principales, se construyó un índice de vulnerabilidad local al dengue (IVL). La asociación del IVL con la enfermedad en la vivienda se evaluó mediante una prueba de ji cuadrada. RESULTADOS: El IVL incluyó cinco componentes explicando el 63% de la varianza y fue clasificado en tres categorías: baja, media y alta. Se observó una asociación significativa entre el aumento de la vulnerabilidad y la prevalencia del reporte de casos de dengue en las localidades. CONCLUSIÓN: El estudio de la vulnerabilidad al dengue permite identificar necesidades locales específicas en materia de promoción de la salud.
