title: Purchases by heavier drinking young people concentrated in lower priced beverages: Implications for policy.
abstract: Alcohol is an increasingly important risk factor in the global burden of disease. The acute harms experienced and persistence of drinking patterns established in adolescence motivate investigating influences on youth drinking. The aim is to examine association between heavier drinking in young people and their choice of beverage type, purchase outlet and price.
  
  
  
  A nationally representative sample of New Zealand drinkers (N = 1056) aged 16-19 years recruited using random digit dialling was surveyed in 2012 as part of the International Alcohol Control study. Typical quantities consumed and frequency of alcohol consumption categorised respondents into lower, medium and heavier consumption groups. Beverage choice, prices paid and on or off-premise purchase were related to consumption using univariate analysis. Logistic analysis was used to examine multivariate factors predicting membership of consumption groups.
  
  
  
  Twenty percent of the sample consumed six or more drinks at least once a week, increasing to 1 in 4 for those 18 years and older. Heavier drinkers consumed more alcohol in the form of ready to drinks (RTD) especially high-potency RTDs. Lower consumers drank greater proportion of wine. Heavier drinkers paid less than medium consumers who paid less than lower consumers. High-potency RTDs were cheaper per unit of alcohol than other beverages and chosen by heavier drinkers resulting in lower prices.
  
  
  
  Heavy consumption of alcohol remains common in New Zealand young drinkers. Heavier drinkers paid less to purchase alcohol and consumed more alcohol in the form of high-potency RTDs.
