Value

drinks_now: Drank at all in the last 12 months (drinker, non_drinker).
drink_freq_7d: Frequency of drinking, expressed in terms of the expected number of drinking ocassions per week (numerical variable calculated from categorical responses to how frequently someone drinks).

adrinkmonth: Youth drinks at least once a month (yes, no).
adrinklastweek: Youth drank in the last week (yes, no).

Details

Combines information from adults and children. In general, someone is classed as a drinker even if they only reported drinking once or twice a year - which is a less strict definition than used by some other surveys. Any missing data is supplemented by responses to if currently drinks or if always non-drinker.

For youth drinking, variables are also created for: drinks at least once a week, drinks at least once a month, and drank in the last week.

Note: The Scottish Health Survey dataset does not have drinking data on children younger than 16 years old.
