[Analysis of the influencing factors of abnormal blood pressure and electrocardiogram in occupational motor vehicle drivers].

Objective: To explore the influencing factors of abnormal blood pressure and electrocardiogram (ECG) in occupational motor vehicle drivers. Methods: In January 2024, a cluster sampling method was used to study 606 occupational motor vehicle drivers from a transportation service enterprise in Beijing who completed occupational health examination in 2023 in Peking University Third Hospital as observation group and 596 non-occupational motor vehicle drivers as control group. The data of personal history, occupational history, blood pressure and ECG were collected, and the effects of occupational motor vehicle driving on hypertension and ECG were analyzed by multivariate logistic regression. Results: The age of workers in the observation group was (34.1±7.8) years old, and the length of service was (7.0±7.1) years. The age of the control group was (33.8±7.6) years old, and the working age was (7.7±6.5) years. There was no significant difference in age and length of service between the two groups (t=0.62, -1.90, P=0.538, 0.057). Systolic blood pressure (133.0±14.7) mmHg, diastolic blood pressure (83.7±11.6) mmHg, hypertension detection rate of 33.0% (200/606), ECG abnormality detection rate of 39.9% (242/606). They were significantly higher than those in the control group [ (127.8±14.4) mmHg, (77.5±11.0) mmHg, 24.7% (147/596), 31.0% (185/596) ], and the differences were statistically significant (P<0.05). Multivariate logistic regression analysis showed that occupational motor vehicle driving were risk factors for hypertension and abnormal ECG (OR= 1.210, 1.578; 95% CI: 1.145-1.231, 1.237-2.012; P<0.001) . Conclusion: Occupational motor vehicle driving may increase the risk of hypertension and abnormal ECG in workers.
