Lifetime daily alcohol intake
Self-reported lifetime daily alcohol intake - baseline
Lifetime Daily Alcohol Intake (LDAI) at baseline is a measure of the amount of alcoholic drinks (beer, wine, or liquor) consumed per day during the period the participants drank the most in their lifetime.
Participants are asked the following questions:
- In your entire life, have you had at least 12 drinks of any kind of alcoholic beverage?
- In your entire life, when you drank the most, about how often did you drink any type of alcoholic beverage, including beer, wine and liquor?
If a participant replies "no" to item 1, LDAI is categorized as less than one drink per month (response code = 9).
Response choices for item 2:
| Response | Response code | Value |
|---|---|---|
| 6+ drinks per day | 1 | 6.0 |
| 4-5 drinks per day | 2 | 4.5 |
| 2-3 drinks per day | 3 | 2.5 |
| 1 drink per day | 4 | 1.0 |
| 5-6 drinks per week | 5 | 0.8 |
| 2-4 drinks per week | 6 | 0.4 |
| 1 drink per week | 7 | 0.2 |
| 1-3 drinks per month | 8 | 0.1 |
| Less than one drink per month | 9 | 0.0 |
