Objective: Investigation on the prevalence of thyroid nodule in physical examination population of teachers in-service in Putuo District of Shanghai city and the possible influencing factors was analyzed. Methods: Method of cross-sectional study was used, from January 2018 to December 2018, 1 755 person times of teachers in-service in Putuo district who had physical examination in the physical examination station were selected for thyroid ultrasound and blood biochemical examination, and their work position, mental pressure, sleep and other information were collected. Results: The prevalence rate of thyroid nodules of the teachers in-service in Putuo district was 68.60% (1 204/1 755), the size of nodules ranged from 2 mm×1 mm to 43 mm×38 mm, and 854 cases (70.93%) with multiple nodules were significantly more than 350 cases (29.07%) with single nodules, among which double leaf nodules and solid nodules were more common. The prevalence was 79.14% (751/949) in females, which was significantly higher than 56.20% (453/806) in males (?字2=106.415, P<0.001). The prevalence of thyroid nodule increased with the increase of age. The highest prevalence was found in people ≥51 years old, which was 77.78%(?字2=145.620, P<0.001). The prevalence of different genders increased with age (P<0.001), the prevalence of women in all age groups was higher than that of men, the differences were statistically significant (P<0.05). There was no significant difference in the prevalence among different posts (P>0.05). Logistic regression analysis showed that: gender (OR=2.836, 95%CI: 2.149~3.743), age (OR=1.736, 95%CI: 1.500~2.008), post (OR=1.945, 95%CI: 1.722~2.196), blood glucose (OR=3.369, 95%CI: 1.822~6.229), mental pressure (OR=9.884, 95%CI: 6.289~15.532), blood lipid (OR=9.121, 95%CI: 4.897~16.988), sleep quality (OR= 9.513, 95%CI: 6.322~14.313) were the risk factors of thyroid nodule. Conclusion: The prevalence of thyroid nodule of teachers in-service in Putuo district of Shanghai is high, the occurrence in woman is higher than that in men. Gender, age, post, blood sugar, mental pressure, blood lipid, sleep quality and so on are the risk factors of thyroid nodule. Work should be arranged reasonably, the concept of health management should be setted up and the level of health management should be improved in teachers. |
