Abstract: Background: Hypertension is a major global health concern, often influenced by lifestyle and occupational stress. Working hours, a modifiable occupational factor, may contribute to elevated blood pressure, yet remains underexplored in community health settings. Objectives: To evaluate the relationship between daily working hours and blood pressure levels among adults attending a community-based blood pressure screening camp. Methods: A cross-sectional study was conducted during a free blood pressure screening camp on World Hypertension Day. Adults aged 18 years and above were enrolled. Data on age, gender, BMI, working hours per day, smoking, alcohol consumption, and history of asthma or COPD were collected. Blood pressure was measured using a standardized protocol. Participants were categorized based on working hours (<8, 8-10, >10 hours/day). Statistical analysis included ANOVA, chi-square test, and correlation analysis to evaluate associations between working hours and blood pressure. Results: A total of [257] participants were included. A positive association was observed between longer working hours and both systolic and diastolic blood pressure (p < 0.05). Participants working 8-10 hours/day had a significantly higher mean systolic BP compared to those working <8 hours. Confounding factors such as BMI, smoking, and comorbidities were controlled in multivariate analysis, confirming working hours as an independent predictor of elevated BP. Conclusion: Prolonged working hours are significantly associated with increased blood pressure among adults. Public health interventions targeting occupational stress management could contribute to hypertension prevention.
