Occupational exposure’s effects on the risk of arterial hypertension among Algerian workers

Background : The working environment plays a critical role in employee health, with occupational factors significantly contributing to the risk of arterial hypertension, a major public health concern. The objective of this study was to investigate the influence of occupational exposure on the risk of hypertension among workers undergoing medical surveillance in Algiers. Methods : Participants were randomly selected from those attending mandatory medical examinations in 2019. Data collection involved self-administered questionnaires, medical record reviews, and workplace task analyses. Statistical analyses were conducted using R software, employing descriptive statistics and regression models, with significance set at p < 0.05. Results: The study included 350 participants (mean age, 41 ± 8 years; 78.29% male). The prevalence of post-recruitment hypertension was 13.14%. Multivariable analysis revealed that regular public interaction significantly increased the risk of hypertension (Adjusted OR = 2.97 [1.20 ; 7.36]). Obesity at recruitment was strongly associated with hypertension development (Adjusted OR = 9.05 [2.52 ; 32.53]). Prolonged screen time was correlated with both systolic blood pressure difference (Adjusted Coef. β : 6.41 [1.00 ; 11.83]) and diastolic blood pressure difference (Adjusted Coef. β : 5.28 [1.36 ; 9.19]) since the recruitment visit. Conclusion : Regular public interaction likely elevates hypertension risk due to stress, consistent with existing literature. Obesity's pronounced impact highlights the need for close monitoring of this modifiable risk factor by occupational health professionals. Workplace health strategies are essential to mitigate cardiovascular risks among workers.
