Abstract: Objective To analyze the prevalence and influencing factors of metabolic syndrome（MS） and common chronic diseases among the workers of the power grid enterprise,so as to provide a scientific basis for the health management of the workers inpower grid enterprise. Methods Purposive sampling method was used to select 881 research subjects from power grid enterprises in 2023. The chi-square test were applied to analyze the variation in MS and common chronic diseases detection rates of power grid workers in different genders and ages,and the influencing factors were analyzed by binary logistic regression equation. Results The prevalence of chronic diseases among 881 power grid workers was 75.48%（665/881）,and the prevalence of chronic disease co-morbidities was 42.45%（374/881）. Among them,the prevalence of MS was 18.16%,and the prevalence of hyperuricemia was the highest（47.45%）. The detection rates of MS,overweight,obesity,and hyperuricemia in male workers of this enterprise were higher than those in females（all P<0.05）.The differences in the distribution of MS,overweight,hypertension,and hyperuricemia in different age groups were statistically significant（all P<0.05）. Age≥40 years（OR=2.479,95%CI：1.589-3.867）,BMI of overweight（OR=7.126,95%CI：4.229-12.006） and obesity（OR=37.046,95%CI：19.569-70.132） were all risk factors for MS（all P<0.05）. Conclusion The prevalence of chronic diseases among workers in power grid enterprise is high.Attention should be paid to the health status of middle-aged（≥40 years old）,overweight,and obese workers,and further strengthen the health management of workers to improve their health literacy. The combination of daily health monitoring and personal behavioral intervention is adopted to reduce the risk of disease.
