Objectives: Smoking cessation is very important for workers due to the possibility of exposure to additional environmental risks in the workplace environment. This study was performed to determine the changes in the Framingham Risk Score (FRS) and 10-year risk of cardiovascular disease (CVD) of employees before smoking cessation and after 6 months.
Materials and methods: Five hundred and sixty-two employees who want to quit smoking were included in the study. In this prospective study, the baseline and 6-month FRS, and 10-year risk of CVD of workers were calculated. Furthermore, the Hospital Anxiety and Depression Scale was used for assessments of employees' anxiety and depression symptoms.
Results: After 6 months, 37% of the participants quit smoking. It was determined that 11.9% of employees have a high CVD risk and 10.6% moderate CVD risk. After 6 months, there was a statistically significant reduction in FRS who quit smoking (P < 0.001). In addition, within the 6 months after smoking cessation, 10-year coronary heart disease risk reduction was higher in quitters than those who cannot quit smoking (47.6% decrease in quitters and 14.9% in nonquitters, P < 0.001). Significant decreases in fasting blood glucose levels were determined after smoking cessation (P = 0.003).
Conclusions: The FRS and CVD risk of smoker employees were decreased 6 months after smoking cessation. In 6 months, CVD risk is reduced in almost half of those who quit smoking. Even in the short term, it is possible to reduce the CVD risk of a worker who quits smoking.
