The objective of this study was to determine the sociodemographic factors associated with certain KAP levels regarding dengue in two hyperendemic cities in Colombia using the MCA technique.Materials and Methods Study sitesKAP surveys were collected between December 2012 and April of 2013 in the cities of Colombia, Arauca and Armenia. Arauca, the capital city of the Arauca Department, has 85,994 inhabitants and is located on the border with Venezuela at 125 meters above mean sea level (MAMSL). It has a mean temperature of 30 . Armenia, with 293,614 inhabitants, is the capital city of the Quind Department and is located in the center of the country at 1,483 MAMSL, with temperatures ranging from 18 to 29 .SampleWe surveyed 3,998 households in the context of a cluster-randomized trial, following the same methods of Quintero et al [39] where a grid was overlapped in a satellite image of the two cities. Areas with empty land and non-residential zones were excluded. Of the remainder, 20 squares were randomly selected in each city, and 100 households were surveyed in each Ciclosporin web square beginning by the south-west corner of each square; the group of houses was called cluster. Personnel from the health authorities of both cities visited each household and invited the responsible adult available to Mequitazine chemical information participate in the study. In the case of absence two additional visits in different schedules were done. If contact was not possible after three visits the household was replaced by the contiguous household (Response rate: 99.95 ).InstrumentsThe KAP questionnaire was based on a review of published studies using KAP surveys between 2001 and 2012 and on a review of the questionnaires provided by the authors of such studies. We developed our KAP survey using a combination of questions from various KAP questionnaires. The new questionnaire was then piloted in a village near one of the study sites. After adaptation to the language in the local community, the 84-question survey was applied to each household using the mobile application e-mocha1, created by the Center for Clinical Global Health Education at the Johns Hopkins School of Medicine. The KAP survey had five sections: sociodemographic and gender decision-making information and knowledge, attitudes, and practices data (S1 File). The sociodemographic section collected information about age, sex, education, income, number of persons per household, dwelling materials (floors and walls), migration, and accessPLOS Neglected Tropical Diseases | DOI:10.1371/journal.pntd.0005016 September 28,3 /KAP Surveys and Dengue Control in Colombiato public services. Given the already documented difficulties to capture household wealth with self-reported income [18], we used an additional measurement of socioeconomic strata that is used in Colombia to classify areas in the cities on a scale from 1 (lowest) to 6 (highest) and it is usually utilized to grant subsidies to the lowest-income population (strata 1) and to charge differential fees for public sanitation services [40,41]. The gender decision-making segment inquired about who decides about the health care of their own and others, daily expenses, large expenses, and household maintenance. The gender decision-making questions were extracted from the women’s module of the Demographic Health Survey [42].
