Smoking Increases Diabetes Risks


By: Daniel Trecroci

Swedish researchers say that smoking is associated with both poor blood glucose control and microalbuminuria (protein in the urine) that indicates early kidney disease and increased heart disease risk.

Smoking is also widespread in young people with type 1 and middle-aged people with types 1 and 2.

Smoking habits were reported to the Swedish National Diabetes Register, with data from hospitals and primary healthcare centers.

Patient characteristics included were age, gender, type of treatment, diabetes duration, A1C, body mass index, blood pressure, use of anti-hypertensive and lipid-lowering drugs and microalbuminuria.

  • Twelve to 15 percent of people with type 1 were smokers between 1996 to 2001
  • Twelve to 16 percent of type 1 females under the age of 30 smoked
  • Thirteen to 17 percent of type 1 and 2 females between 30 and 59 smoked
  • Six to 9 percent of older type 1s and 2s smoked

Smoking type 1 and type 2 patients in 2001 had higher average A1C levels but lower mean body mass index than nonsmokers.

Smokers also had higher frequencies of microalbuminuria in both type 1 and type 2.
