Deconvolving blood-alcohol concentration and alcohol beverage consumption from sensor measurements of transdermal alcohol

Deconvolving an estimate of breath measured blood alcohol concentration from biosensor collected transdermal ethanol data

Biosensor measurement of transdermal alcohol oncentration in perspiration exhibits significant variance from subject to subject and device to device. Short duration data collected in a controlled clinical setting is used to calibrate a forward model for ethanol transport from the blood to the sensor. The calibrated model is then used to invert transdermal signals collected in the field (short o...

Alcohol consumption, beverage prices and measurement error.

OBJECTIVE Alcohol price data collected by the American Chamber of Commerce Researchers Association (ACCRA) have been widely used in studies of alcohol consumption and related behaviors. A number of problems with these data suggest that they contain substantial measurement error, which biases conventional statistical estimators toward a finding of little or no effect of prices on behavior. We te...

Alcohol Consumption and Blood Pressure

The relationship between alcohol consumption and systolic and diastolic blood pressure (BP) was examined in 2482 men and 2301 women 20 years of age or older in nine North American populations. Men at the highest level of alcohol consumption (^ 30 ml alcohol per day) had the highest BP, while women either at the highest lerel of alcohol consumption or consuming no alcohol had the highest BP. Men...

Young people's blood alcohol concentration and the alcohol consumption city law, Brazil.

The paper assesses blood alcohol concentration and risk behaviors for traffic accidents before and after the implementation of a law which prohibits the use of alcoholic beverages on city gas stations. In Porto Alegre, Southern Brazil, young people go out at night and drive to gas station convenience stores to buy alcoholic beverages which are consumed on the premises of parking lots in gas sta...
