Grams of alcohol per day at baseline is a measure of how much alcohol (beer, wine, and liquor) a participant consumed in the past 12 months. Participants are first asked whether or not they consumed at least 12 drinks ever and in the last 12 months. Individuals who answer “no” to both questions were given a total alcohol consumption of 0. Those who respond “yes” to consuming at least 12 drinks in the past 12 months are then asked to estimate the quantity consumed of each of the following alcoholic beverages: beer, wine, and liquor. A value is applied to each response choice based on the table below. The number of drinks value is then multiplied by grams of alcohol per drink type and then summed across all drink types to determine total grams of alcohol consumed. Totals range from 0 to 234.6g, with higher values indicating greater alcohol consumption.
Participants are asked the following questions:
Response choices for each item:
|6+ drinks/glasses per day||1||6.0|
|4-5 drinks/glasses per day||2||4.5|
|2-3 drinks/glasses per day||3||2.5|
|1 drinks/glasses per day||4||1.0|
|5-6 drinks/glasses per week||5||0.8|
|2-4 drinks/glasses per week||6||0.4|
|1 drink/glass per week||7||0.2|
|1-3 drink/glass per month||8||0.1|
|Less than one drink/glass per month||9||0.0|
Grams of alcohol per drink/glass:
|Drink type||Grams of alcohol|
Note: This variable is not normally distributed, with the majority of values at 0 and some high values.
