Knowledge, attitudes and practices regarding dengue fever among adults of high and low socioeconomic groups

Objective: To ascertain the knowledge, attitudes and practices of selected adult population in Pakistan regarding Dengue Fever. Methods: A cross sectional survey was conducted among selected communities with different socio-economic backgrounds in Karachi, Pakistan. A sample size of 440 adults (aged 18 years and above) were interviewed using a pre-tested questionnaire regarding their knowledge, attitude and practices about dengue fever. A composite scoring system, based on the answers given in the questionnaire, was used to establish the level of awareness in the population. The division of the higher and lower socio-economic groups was based on their income and locality; both these variables were determined as a part of our survey. Results: Data from 400 respondents (244 males, 156 females) was used for primary analysis. About thirty five percent of the sample had adequate knowledge about dengue fever and its vector. Knowledge had significant associations with education (p= 0.004) and socioeconomic status (p=0.02). The high socioeconomic group showed better preventive practices. Conclusion: Knowledge of dengue is inadequate in the low socioeconomic class. Better preventive practices against the vector are prevalent in the high socioeconomic group. Hence, a greater focus should be accorded to the low socioeconomic areas in future health campaigns.
