Associations between Recreational and Commuter Cycling, Changes in Cycling, and Type 2 Diabetes Risk

The aim of this study [attached] was to examine prospective associations between recreational and commuter cycling, changes in cycling habits, and risk of type-2 diabetes (T2D) in Danish adults from the Diet, Cancer and Health cohort study. At baseline (from 1993 to 1997) 24,623 men and 27,890 women from Denmark, 50–65 years of age and free of T2D and other chronic diseases, underwent a number of assessments––including completing a lifestyle questionnaire also addressing cycling habits. Approximately 5 year later, at a second examination, participants completed a new, updated lifestyle questionnaire. Cox regression was used to estimate hazard ratios (HRs) of incident T2D registered in the Danish National Diabetes Registry, according to recreational and commuter cycling and changes in cycling habits, with adjustment for a priori known T2D risk factors.

Quite amazing (and shocking?), … authors found that “commuter and recreational cycling was consistently associated with lower risk of T2D in Danish adults.” Authors claim that their results provide evidence that late-in-life initiation of, or continued, engagement in cycling lowers risk of T2D. Near where we live, there are A LOT of “cyclists”––and during the past 3 years I cannot say that I have ever seen a single one of the hundreds of them … that is clinically overweight. And, certainly none that is MORBIDLY OBESE. Professor Puga is going to have a Field Day with this epidemiological study and its conclusions. So, ….. which comes first? The chicken? or the egg?

Dr. Nebert –This will solve not only Dr. Puga’s worries, … but also the global warming worries of Drs. Eaton, Vasiliou, and Feyereisen.
