Objective:The SF-36 Scale was utilized to compare the differences in the dimensions of survival quality between subway microwave contact personnel and administrative personnel to provide a scientific basis for improving the quality of life of microwave contact personnel.Methods:In October 2023, 264 occupational personnel exposed to microwaves were selected as the microwave exposure group, and 104 administrative personnel not exposed to microwaves in a railroad enterprise were selected as the administrative control group. The self-administered basic data questionnaire and SF-36 Scale were applied to investigate the basic conditions, daily behaviors and survival quality of the research objects. And the microwave exposure doses of each post were measured. The differences in basic conditions, daily behaviors and survival quality of the microwave exposure group and the administrative control group were analyzed. And logistic regression was used to analyze the influencing factors of survival quality in the microwave exposure group.Results:There were significant differences in gender, age, marital status, smoking status and sleep status between the microwave exposure group and the administrative control group ( P<0.05) . The microwave exposure group had lower scores than the administrative control group in the six dimensions of role physical, body pain, general health, vitality, social function, mental health and SF-36 average total score, and had higher score in reported health transition ( P<0.05) . The logistic regression analysis showed that the probability of low total SF-36 score in microwave exposure group with bachelor's degree or above was 0.46 times that of junior college degree (95% CI: 0.24-0.90, P=0.023) . The probability of low total SF-36 score in microwave exposure group with exercised 4 or more times per week was 4.27 times that of those who never or occasionally exercised (95% CI: 1.41-13.00, P=0.010) . The probabilities of low total SF-36 score in microwave exposure group with sleep light and dream, wake up in the middle night and hard to fall asleep were 11.04 and 7.38 times higher than those without sleep disturbance (95% CI: 3.35-36.32, P<0.001; 95% CI: 1.42-38.50, P=0.018) . The probability of low total SF-36 score in microwave exposure group with daily dose of 1.74 μW·h/cm 2 was 1.75 times that of the daily dose of 1.02 μW·h/cm 2 (95% CI: 1.08-3.82, P=0.008) . Conclusion:The education level, physical exercise, sleep status and microwave exposure dose are important factors affecting the survival quality of microwave exposed personnel. Occupational health education and behavioral life intervention should be strengthened to improve their survival quality.
