Fat toddlers are hurt more by second-hand smoke

The damage from being around tobacco smoke starts early. We have long known that second-hand smoke is not good for toddlers. This small study (52 toddlers and 107 adolescents), reported in Science Daily, shows that one marker of damage is twice as high for fat toddlers and adolescents than for normal-size kids, and "Toddlers had a four times greater risk of secondhand smoke exposure when compared to adolescents, despite having similar reported home exposures." They got exposure levels from blood tests.
