Family characteristics, Basic Sanitation trought Health promotion moderating in prevention Dengue in Dom Alexo, Dili 2024

Timor-Leste is one of the countries with a high incidence of dengue fever (DHF), especially during the rainy season. Until now, there is no specific effective treatment for dengue virus, so prevention is an important step in reducing the spread of this disease. This study aims to determine the relationship between family characteristics and basic sanitation with DHF prevention through the moderating variable of health promotion in Dom-Aleixo Administrative Postu, Dili Municipality, in 2024. The research method used was descriptive quantitative with a cross-sectional approach. The study population included all heads of households in Dom-Aleixo Administrative Postu, with a total of 122,699 households, and the sample taken was 100 households. The data analysis technique used Pearson Product Moment, and took into account research ethics. The results showed that there was a moderate relationship between family characteristics and DHF incidence (r = 0.413). When moderated by health promotion, this relationship became stronger (r = 0.548). In addition, basic sanitation showed a very strong association with DHF incidence (r = 0.686), and this association remained very strong when moderated by health promotion (r = 0.545). Overall, the combination of family characteristics and basic sanitation moderated by health promotion had a very strong association with DHF incidence (r = 0.693). This study implies that health promotion plays an important role in strengthening the relationship between family characteristics and basic sanitation with DHF prevention, and that improving health promotion can be an effective strategy in reducing DHF cases in Timor-Leste.
