Alcohol Consumption

The most recent alcohol consumption record in the five years before entry into the study was used to classify participants drinking behaviour. In light of current debates on the U/J-shaped relationship observed between alcohol consumption and aggregated CVD outcomes10 five drinking categories were defined including: (1) non-drinkers (Read66 codes such as "tee-total" and "non-drinkers"), former drinkers (those with codes for "stopped drinking alcohol"
and/or "ex-drinker"), occasional drinkers (those with codes for "drinks rarely" and/or "drinks occasionally"), current moderate drinkers (those who had a code for current alcohol consumer and an indicator of whether they drank within daily [32g or 24g of alcohol for men and women respectively]
and/or weekly [168g of alcohol for men and 112g for women] recommended sensible drinking limits for the UK at the time of observation69) and current heavy drinkers (defined as those who exceeded daily and/or weekly sensible drinking limits). We also utilised data fields with information entered on daily and/or weekly amount of alcohol consumed to define participants as non-drinkers, moderate drinkers (drank within daily and/or weekly guidelines) and heavy drinkers. Weekly alcohol data was available as a continuous variable, so we were able to classify consumption using standard thresholds
Data on daily alcohol intake was entered using categories of: (1) < 1 UK unit (8 grams of ethanol), (2) 1-2 UK units, (3) 3-6 UK units, (4) 7-9 UK units, and (5) > 9 UK units [Read codes 1362.00-1366.00], for which we defined moderate drinking as anything >1 UK
unit but less than 3 (women) or 7 (men) UK units. Unfortunately information on binge drinking was only available for a select minority of the cohort (~100 people) therefore a separate category for this drinking behaviour was not defined (but these patients were coded as heavy drinkers). We reclassified non-drinkers as former drinkers if they had any record of drinking recorded in their entire clinical record entered on CPRD prior to study entry (in cases whereby non-drinkers had no record of drinking before entering the study we assumed that they were not former drinkers). This resulted in 19,853 (out of 184,747; 10.7%) non-drinkers being recoded as former drinkers, a further 6,826 (3.7%)
participants were reclassified through having a positive history of alcohol abuse.
In the Clinical Practice Research Datalink (CPRD, primary care data) we extracted information on alcohol consumption based on:
- Clinician-recorded alcohol consumption information
- Stuctured data elements related to daily/weekly alcohol unit consumption
- Evidence of alcohol abuse
- Evidence of alcohol-related harm
We extracted alcohol unit intake information using the structured data part (entity type 5) of the additional table (units recorded in data2) field. We additionally extract information on intake through clinician-recorded classifications using Read terms (see below).
