Abstract

Introduction: Clean and Healthy Living Behavior (PHBS) includes practices such as handwashing with soap, maintaining personal and environmental hygiene, proper waste disposal, and consuming nutritious food. According to the World Health Organization (WHO, 2021), up to 60% of childhood diarrhea cases can be prevented through proper hand hygiene. The Indonesian Ministry of Health (2020) also reports that the PHBS program in schools significantly reduces the incidence of infectious diseases. This study aims to evaluate the effectiveness of a PHBS education program in promoting disease prevention and improving health behaviors among elementary school students. Methods: A pre-experimental design was used, involving 50 students from SDN Bawakaraeng III Makassar. Data were collected through pre- and post-intervention tests and observational checklists. The program, conducted over four days, with sessions on personal hygiene, environmental cleanliness, and healthy eating habits. Statistical analysis was performed using the Wilcoxon signed-rank test to compare pre- and post-test scores, and McNemar’s test was used to assess changes in students' health practices. Results: Pre-test results showed an average score of 65 (out of 100), while post-test results increased to an average score of 85, indicating a significant improvement of 20 points (p-value = 0.031) based on the Wilcoxon test. The improvement was greater among female students, with an average increase of 23 points, compared to male students, whose average increase was 17 points. Observations revealed that 50% of students did not know the correct handwashing steps before the intervention, which increased to 75% after the program. Additionally, students' adherence to PHBS practices improved significantly, rising from 50% to 70% (p-value = 0.013) as assessed by McNemar’s test. Conclusion: The findings demonstrate that the PHBS education program significantly improved students' awareness and practices regarding disease prevention, as evidenced by the measurable increases in knowledge and behavior change.

Abstract

Digital technology increasingly shapes adolescent health behavior; however, little is known about how adolescents in remote coastal communities adapt to digital health information environments. This study aims to explore how digital technology influences adolescent health behaviors and how environmental and social factors shape adolescents’ adaptation to digital technology in a coastal community. This qualitative study employed a phenomenological approach. Data were collected through in-depth interviews with 27 adolescents aged 15–19 years and two focus group discussions conducted in Mandangin Island, Madura, Indonesia. Participants were selected using purposive sampling based on their access to digital devices and internet connectivity. Data were analyzed using thematic analysis supported by NVivo 12 software. Digital technology, particularly social media platforms such as TikTok, Instagram, and YouTube, emerged as the primary source of health information for adolescents. Participants reported increased awareness of healthy behaviors, including diet, physical activity, and mental well-being. However, significant challenges were identified, including limited internet access, unequal device ownership, and difficulties in distinguishing credible information from misinformation. Peer influence played a central role in shaping how adolescents adopt and interpret online health information. Digital technology has the potential to support positive health behavior among adolescents in coastal communities. Nevertheless, digital inequality and limited digital health literacy restrict its effectiveness. Strengthening digital literacy and improving equitable access to technology are essential to optimize digital health interventions for adolescents in underserved coastal areas Keywords: Adolescent Health, Digital Health Literacy, Health Behavior, Digital Divide, Coastal Community, Qualitative Research
