The links between
smoking and increased risk for cancer and respiratory and cardiovascular
disease are well-known, but the association between smoking and diabetes has
received less attention. A new analysis
of 88 existing studies that included almost six million people has found that
current smokers and people exposed to secondhand smoke have a significantly
increased risk of developing type 2 diabetes.
The good news is that after quitting, over time the risk for diabetes
decreases.
The study found
a dose-response relationship between smoking and diabetes risk. Compared with
those who have never smoked, light smokers have a 21% increased risk of type 2
diabetes, moderate smokers have a 34% increased risk, and heavy smokers have a
57% increased risk. Those who do not
smoke but are regularly exposed to second hand smoke have a 22% increased risk
of type 2 diabetes. Diabetes risk among
quitters does substantially decline over time.
Among those who quit within the past 5 to 9 years their increased risk
falls to 18% and among those who have quit a decade ago or more saw their
smoking related diabetes risk fall to 11%.
What to do: If you smoke, try to quit. Previous
unsuccessful efforts to quit do not mean that you cannot succeed. Keep
trying. Discuss smoking cessation treatment options with your healthcare
provider. Check out www.nyc.gov/nycquits or call x311 to learn
