Since 2004 ESS is used for sleepiness screening in patient olders than 40 at Bordeaux and Cenon primary healthcare centers. Many others informations are recorded like : patient status – smoker or no, -drinkers or no. 33962 healthcare checkups were performed from 2004 to December 31, 2008. We segmented the 33962 checkups on the basis these datas : smokers (n = 16419), occasional smokers (n = 10599), non smokers (n = 6944) ; alcool drinkers (n = 3434), occasional drinkers (n = 21488), non drinkers (n = 9040). The comparison of the distribution of ESS between populations was conducted using a test khi2. There is a significant difference in distribution between smokers and non smokers (P < 0.0001). For the smokers, distribution of scores was shifted toward lower scores than that among nonsmokers. He also found a significant difference between drinkers and nondrinkers (P < 0.0001). For alcool drinkers, distribution of scores is shifted towards higher scores than that observed among non-drinkers. The increase in ESS score with alcohol is consistent with findings of Koutsourelakis et al [1] The decrease in ESS score with smoking is consistent with what is observed among drivers of trucks [2] who use tobacco against drowsiness.
