Title: May hepa sa basura: A quantitative study on the prevalence of Hepatitis B among garbage collectors in Baguio City, Philippines
Abstract:
Hepatitis B virus (HBV) remains a persistent public health concern, particularly among occupational groups with heightened exposure to biological waste. This study examined the prevalence of Hepatitis B among registered male garbage collectors in Baguio City, Philippines, and explored the relationships between HBV status and three variables: occupational exposure, knowledge about HBV, and workplace conditions. Utilizing a quantitative correlational research design, the study sampled 59 participants from the City General Services Office. Data were collected through a pretested structured questionnaire and rapid HBsAg testing, with analyses performed using descriptive statistics and chi-square tests (α = 0.01). The findings revealed a 3.4% HBV prevalence rate, with 66.1% of respondents unvaccinated and 84.7% employed for over three months. Most participants reported moderate exposure to risk factors (M = 2.23), insufficient knowledge about HBV (M = 2.48), and subpar workplace conditions (M = 2.40). Although exposure (χ² = 1.87, p = .17) and knowledge (χ² = .659, p = .42) were not significantly associated with HBV status, workplace conditions were statistically significant (χ² = 6.65, p = .01), indicating that environmental and systemic factors play a critical role in infection risk. These results highlight the inadequacy of current protective measures and underscore the importance of targeted interventions—including improved safety training, provision of protective equipment, and accessible vaccination programs. Prioritizing occupational health for waste collectors not only supports individual well-being but contributes to broader infectious disease control efforts.
