Cigarette smoking and diabetes: an update
1Department of Metabolic Diseases and Nutrition, Heinrich-Heine University Düsseldorf, Germany.
Summary
Smoking significantly worsens diabetes complications and increases mortality risk. Quitting smoking offers the most effective intervention for diabetic patients, yet current cessation programs remain largely unsuccessful.
Area of Science:
- Endocrinology
- Public Health
- Nephrology
Background:
- Cigarette smoking is a prevalent risk factor with known adverse health effects.
- The impact of smoking on diabetes prognosis requires comprehensive understanding.
- Diabetic complications like nephropathy and retinopathy are significant concerns.
Purpose of the Study:
- To review current scientific literature on the association between cigarette smoking and the prognosis of diabetes.
- To evaluate the influence of smoking on the development and progression of diabetic complications.
- To assess the impact of smoking cessation on mortality and complication risks in diabetic individuals.
Main Methods:
- Systematic literature review of English-language articles from MEDLINE (1989-1993) and bibliographies.
- Inclusion of human studies only.
- Analysis of data on smoking status, diabetic complications, and mortality.
Main Results:
- Cigarette smoking is linked to the development and progression of diabetic nephropathy.
- The association between smoking and diabetic retinopathy is less consistent.
- Diabetic patients who smoke have double the all-cause mortality risk compared to non-smokers.
- Smoking cessation is identified as the most cost-effective risk factor intervention for diabetes.
Conclusions:
- Smoking status is a critical factor to consider in clinical studies of diabetic nephropathy.
- While smoking cessation offers substantial theoretical benefits for diabetic patients, existing programs show limited success.
- Further research and improved interventions are needed to support smoking cessation in diabetes management.
