With regard to drowsy driving, 20.5% answered positively to the Berlin Questionnaire query about falling asleep while driving. Correlates of sleepy driving are reported in Table 2. Sleepy driving was not associated with BMI, hypertension (p=0.07) or gender, but strongly correlated with severity and frequency of snoring and with witnessed apneas.
