Impacts of New Zealand's lowered minimum purchase age on context-specific drinking and related risks.

ABSTRACT:

Aims

The minimum purchase age (MPA) for alcohol in New Zealand (NZ) was reduced from 20 to 18 years in 1999. We assessed the degree to which this change was associated with alterations in uses of drinking contexts, drinking and related problems.

Methods

NZ National Alcohol Surveys among people 14+ years of age provided demographics, frequencies and amounts consumed in drinking places, and problem measures for 1995, 2000 and 2004. Censored regression estimates of parameters of a context-specific dose-response model identified MPA-associated changes in drinking and problems.

Results

The lowered MPA was associated with more frequent drinking at pubs/nightclubs among the newly of-age 18-19-year-olds (b = 15.26, P = 0.009), moderated drinking quantities at these places (b
