4.13 Secondhand smoke and type 2 diabetes

As noted in Section 4.6, individuals with existing diabetes are at greater risk of developing coronary heart disease if exposed to secondhand smoke.1

Research suggests that the risk of developing glucose intolerance (an indicator of high risk for developing type 2 diabetes) is increased in young adults exposed to secondhand smoke over a 15-year period. This study showed that current smokers had the highest rate of development of glucose intolerance, followed by never smokers exposed to secondhand smoke, and unexposed never smokers.2 In older populations, chronic exposure to secondhand smoke is associated with developing type 2 diabetes, and the risk increases with greater daily exposure and the number of years of exposure.36 Further research is needed to confirm this association, and determine if it is causal.
