Aims Like many indigenous peoples, New Zealand Māori bear a heavy burden of alcohol-related harm relative to their non-indigenous compatriots, and disparities are greatest among young adults. We tested the effectiveness of web-based alcohol screening and brief intervention (e- SBI) for reducing hazardous drinking among Māori university students. Design Parallel, double-blind, multi-site, randomized controlled trial. Setting Seven of New Zealand's eight universities. Participants In April 2010, we sent e-mail invitations to all 6697 17-24-year-old Māori students to complete a brief web questionnaire including the Alcohol Use Disorders Identification Test ( AUDIT)- C, a screening tool for hazardous and harmful drinking. Those screening positive were computer randomized to: <10 minutes of web-based alcohol assessment and personalized feedback (intervention) or screening alone (control). Measurements We conducted a fully automated 5-month follow-up assessment with observers and participants blinded to study hypotheses, design and intervention delivery. Pre-determined primary outcomes were: (i) frequency of drinking, (ii) amount consumed per typical drinking occasion, (iii) overall volume of alcohol consumed and (iv) academic problems. Findings Of the participants, 1789 were hazardous or harmful drinkers ( AUDIT- C ≥ 4) and were randomized: 850 to control, 939 to intervention. Follow-up assessments were completed by 682 controls (80%) and 733 intervention group members (78%). Relative to controls, participants receiving intervention drank less often [ RR = 0.89; 95% confidence interval (CI): 0.82-0.97], less per drinking occasion ( RR = 0.92; 95% CI: 0.84-1.00), less overall ( RR = 0.78; 95% CI: 0.69-0.89) and had fewer academic problems ( RR = 0.81; 95% CI: 0.69-0.95). Conclusions Web-based screening and brief intervention reduced hazardous and harmful drinking among non-help-seeking Māori students in a large-scale pragmatic trial. The study has wider implications for behavioural intervention in the important but neglected area of indigenous health. [ABSTRACT FROM AUTHOR]

To determine the effect of offering smokers who want to quit easy access to nicotine replacement therapy (NRT), a period of familiarization and choice of product on smoking abstinence at 6 months. Single-blind, randomized controlled trial. New Zealand. A total of 1410 adult smokers who called the national Quitline for quitting support were randomized to usual Quitline care or a box containing different NRT products (patch, gum, inhaler, sublingual tablet, oral pouch) to try for a week prior to quitting, and then to choose one or two of these products for 8 weeks' use. The primary outcome was 7-day point prevalence smoking abstinence 6 months after quit day. Secondary outcomes included continuous abstinence, cigarette consumption, withdrawal, NRT choice and serious adverse events at 1 and 3 weeks and 3 and 6 months. No differences in 6-month quit rates (7-day point prevalence or continuous abstinence) were observed between the groups. However, smokers allocated to the intervention group were more likely to have quit smoking at 3 months [self-reported point prevalence, relative risk (RR) = 1.17, 95% confidence interval (CI): 1.02, 1.35, P = 0.03], had a longer time to relapse (median 70 days versus 28 days, P < 0.01) and used significantly more NRT. The selection box concept was highly acceptable to users, with the patch and inhaler combination the most popular choice (34%). In terms of smoking abstinence at 6 months, offering smokers who want to quit free access to a wide range of nicotine replacement therapy, including a 1-week period of familiarization and choice of up to two products, appears no different to offering reduced cost and choice of nicotine replacement therapy, with no familiarization period.
