Backgroud And Objectives:
As patients with diabetes are at a significantly higher risk of cardiovascular diseases than those without diabetes, it is important to gain a clinical understanding of the differential effects of smoking cessation on several risk factors between patients with and without diabetes.
Materials And Methods:
Patients who participated in a smoking cessation program received an assessment of the outcomes of interest. The outcomes were changes in metabolic parameters and renal function from baseline to 6-month follow-up after the smoking cessation program.
Result:
A total of 1954 patients joined the smoking cessation program, and 1381 patients were in the smoking cessation failure (SCF) group and 573 were in the smoking cessation success (SCS) group. The decrease in HbA1c after smoking cessation was only observed in patients with diabetes. Smoking cessation was also associated with a significant decrease in LDL cholesterol in patients with diabetes. In terms of renal function, smoking cessation was associated with an improvement in eGFR, and the trend was similar in patients with and without diabetes.
Conclusion:
Successful smoking cessation was associated with improvement in renal function. Moreover, it was associated with improvements in HbA1c and LDL cholesterol in patients with diabetes, despite significant weight gain.
