Abstract:
Objective To investigate the influence of the hygienic conditions of working environment on the health of employees in hotels at various levels in Jiangsu Province, China.
Methods The samples of PM10 and PM2.5 in indoor air were collected and measured and a questionnaire survey on the employees were performmed in 288 hotels selected in Jiangsu Province, 2018-2021.The survey involved the general information of the employees, the hygienic conditions of working environment, and personal health status. A total of 2 260 valid questionnaires were collected. Logistic regression model was used to investigate the influencing factors for the health status of employees in hotels.
Results The employees who were male, had a length of service more than 15 years and an, education level of college degree or above, and worked in three-star hotels or above had significantly higher self-reported positive symptoms of ocular, respiratory, and skin symptoms than those in other groups. Gender, education level, type of hotel, and "damp environment" "poor ventilation" and "smell of mildew" in working environment had a significant influence on the positive rates of ocular symptoms (χ2 ranged from 23.15 to 329.36, P < 0.05), respiratory symptoms (χ2 ranged from 11.58 to 279.81, P < 0.05), and skin symptoms (χ2 ranged from 12.33 to 259.71, P < 0.05). Multivariate logistic regression analysis showed that "damp environment" "poor ventilation" and "smell of mildew" in working environment and college degree or above were risk factors for the incidence of ocular symptoms (odds ratioOR=3.07, 95% confidence intervalCI: 2.29-4.12; OR=1.67, 95% CI: 1.31-2.13; OR=3.34, 95% CI: 2.40-4.66;OR=2.19, 95% CI: 1.68-2.86, respectively), respiratory symptoms (OR=2.57, 95% CI: 1.92-3.46; OR=1.89, 95% CI: 1.48-2.41; OR=2.66, 95% CI: 1.91-3.70;OR=1.51, 95% CI: 1.15-1.98, respectively), and skin symptoms (OR=2.30, 95% CI: 1.67-3.17; OR=1.52, 95% CI: 1.15-1.99; OR=3.06, 95% CI: 2.18-4.29;OR=1.43, 95% CI: 1.07-1.92, respectively) among the hotel employees.
Conclusion "Damp environment" "poor ventilation""smell of mildew" in working environment, etc., are risk factors for positive symptoms of ocular, respiratory system, and skin of hotel employees.
