Alternative definitions of high risk for impaired driving : the overlap of high volume, frequent heavy drinking and alcohol dependence.
This paper examines the distributions of past-year volume of ethanol intake, frequency of drinking 5+drinks and alcohol dependence in a representative sample of 18352 U.S. current drinkers aged 18 years or over.
Within categories defined by these three partially overlapping domains, it presents rates of self-perceived impaired driving, i.e. driving after having had too much to drink, in the year preceding interview.
High volume drinkers, those with an average daily ethanol intake of 1 ounce or more, composed 19.7% of current drinkers and accounted for 66.5% of all reported ethanol consumption, 72.6% of all heavy drinking days, 49.2% of all alcohol dependence and 62.8% of all impaired driving incidents.
Frequent heavy drinkers, those who drank 5+drinks at least once a week, composed 12.3% of current drinkers and accounted for 42.9% of all reported ethanol consumption, 81.9% of all heavy drinking days, 40% of all alcohol dependence and 57% of all impaired driving incidents.
Drinkers with DSM-IV alcohol dependence composed 9.9% of current drinkers and accounted for 28.9% of all reported ethanol consumption, 37% of all heavy drinking days and 56.9% of all impaired driving incidents.
The overlap of these three high risk groups, each of which had a probability of at least one impaired driving incident per year, was far from complete. (...)
