The Effect of Noise Exposure on the Incidence of Hypertension Among Scrap Metal Workers in Tanjung Jati Village, Bangkalan–Madura

Background: Hypertension is a major global health problem, and occupational noise is a recognized non-auditory risk factor. In Tanjung Jati Village (Bangkalan–Madura), scrap metal workers are routinely exposed to high noise levels during ship dismantling activities. Objective: To determine the effect of occupational noise exposure on the incidence of hypertension among scrap metal workers. Methods: An analytical observational, cross-sectional study was conducted on 34 workers. Demographic and risk factor data were collected via questionnaire. Blood pressure was measured with a sphygmomanometer, and noise intensity was measured with a calibrated sound level meter at the worker’s ear level. Data were analyzed in SPSS; bivariate analysis included Spearman’s correlation.Results: Most workers operated in areas >85 dB (Lokasi B: 29/34; 85.3%) while 5 (14.7%) worked at ≤85 dB (Lokasi A). Hypertension was identified in 21 workers (61.8%). There was a significant positive correlation between noise intensity and hypertension (Spearman’s r=0.357; p=0.038). Conclusion: Higher workplace noise intensity was associated with a greater incidence of hypertension. Engineering and administrative controls, consistent use of hearing protection, and routine cardiovascular screening are recommended.
