Outcome. Alcohol consumption: Alcohol consumption was assessed from wave 5 (April 2020) until wave 24 (July 2021), with 13 measurements in total. Questions referred to the amount of alcohol consumed: “How many glasses of alcohol did you drink in the past 7 days?” (“in the past 14 days” from wave 7 onwards). In the Netherlands, a standard glass is defined as containing roughly 10 g of alcohol (Gezondheidsraad, Health Council of the Netherlands, 2015). In order to harmonize the data, the average weekly alcohol consumption score (in glasses per week) was calculated (the same variable was created for previous waves of the Lifelines cohort). The scores range from 0 to 70 (all values higher than 70 were recoded to 70).
