Introduction Dengue has been a burden, especially in tropical country. Indonesian Ministry of Health promote dengue prevention through environmental control with 3 M (covering water storage, cleaning water storage, and recycling unused items) practices. Here we analyzed factors associated with dengue prevention behavior in riverbank area of Yogyakarta Province. Methods The study employed cross-sectional survey covering riverbank area of Sendowo, Yogyakarta Province. This study systematically sampled 1 representative from every household to describe the condition of 1 house. We analyzed the associations between subjects' characteristics and dependent variables using Pearson's chi-square test. Results Overall, 89 subjects were enrolled in this study, of whom 11.2% males and 88.8% females. Age and occupation were associated with covering water storage variable with p-value of <0.001 and 0.007, respectively. Recycling unused items variable was associated with monthly income with p-values of 0.045. Furthermore, there were no significant associations between cleaning water storage variable with sex, age, marital status, education level, monthly income, and occupation. Conclusion Age and occupations were associated with covering water storage variable. Recycling unused items variable shows significant association with income. Further multiarea study is necessary to compare our findings with other areas.
