Prevention practices and the factors that influence them are essential for controlling the spread of dengue hemorrhagic fever (DHF) and effective strategic planning. This study aimed to determine the factors associated with the practice of preventing dengue fever in communities in endemic areas of Kubu Raya Regency, West Kalimantan Province, Indonesia. This study was an observational study with a cross-sectional design. The research sample was 379 households in endemic areas using a questionnaire. Collecting data was using a questionnaire with interviews. Bivariate analysis employed Chi-square test, multivariate analysis using logistic regression. Most of the respondents practiced fewer prevention; variables related to dengue fever prevention practices were income, education, knowledge about dengue prevention and health education (mass media). Regression analysis showed that the variables of education, knowledge about dengue prevention, and mass media education were related to the practice of preventing dengue fever. This study indicated that in preventing dengue fever, strategies must be developed to cultivate prevention practices and increase prevention campaigns using mass media and focus on areas with low education and knowledge in dengue prevention.

Previous studies showed the information, motivation, and behavioral skills (IMB) model could be used to predict and prevent reducing sexual risk behaviors. This paper examines the effectiveness of IMB interventions in reducing adolescent’s premarital sexual intentions. A quasy experimental nonequivalent pretest-posttest control group design was conducted among 250 students in 20 secondary schools in Pontianak with intervention IMB models and 100 students in the control group. There was a significant differences of information (delta mean = 3.008; 95% CI = 2.329 to 3.687; p value = 0.0001), motivation (delta mean = 1.532; 95% CI = 0.846 to 2.218; p value = 0, 0001), and skills to refuse or delay premarital sexual behavior (delta mean = 1.604; 95% CI = 0.629 to 2.579; p value = 0.001) on adolescents between before and after the application of the IMB model in secondary students in pontianak, Indonesia. In addition, there were significant differences intention adolescents in the control group and the experimental between before and after the IMB intervention (p value < 0.05). IMB model could be applied as primary prevention on adolescent’s premarital sexual intention through integration in school subjects. It is needed a support and debriefing skills in teachers.
