Factors Associated with Having Family/Whānau or Close Friends Who Used Alcohol or Other Drugs in Harmful Ways among University Students in New Zealand

Abstract

The consequences of alcohol and other drug (AoD) use are well documented. This study investigated factors associated with having family/whānau or close friend who used AoD in harmful ways in New Zealand. Data came from a July–August 2020 cross-sectional survey of students from eight universities (n = 946). Participants were asked if they had family/whānau or close friends in New Zealand who consumed alcohol or used other drugs (cannabis, ecstasy/MDMA, methamphetamine, cocaine, heroin, prescription drugs, inhalants, or other) in a way that negatively impacted them, their family, or close friends in the last 12 months. Logistic regression assessed associations of having family/whānau or close friend who used AoD harmfully with student characteristics. Of respondents, 36.2% (33.1–39.4) had family/whānau or close friend who had consumed alcohol harmfully, and 42.9% (39.5–46.3) had family/whānau or close friend who had used at least one drug harmfully. Respondents’ age and ethnicity were significantly associated with having family/whānau or close friend who used AoD harmfully. The results suggest widespread harmful AoD use and potentially significant second-hand effects of AoD use in New Zealand. These data can be used to supplement information from traditional in-person surveys of individuals using alcohol and other drug (e.g., the New Zealand Health Survey).
