Electronic cigarette use in young people in Great Britain 2013-2014.

OBJECTIVES: The recent growth in the market for electronic cigarettes (e-cigarettes) has led to concerns over their use by young people. It is therefore important to examine trends in the perception and use of e-cigarettes and conventional cigarettes in this group. STUDY DESIGN: Two-wave cross-sectional survey design. METHODS: Young people aged 11-18 in Great Britain were surveyed online by YouGov in 2013 and 2014. Use of e-cigarettes, together with perceived health harms and intention to use were assessed and compared in relation to cigarette smoking history, age and gender. RESULTS: Ever-use of e-cigarettes increased significantly from 4.6% (95% CI 3.8-5.7) in 2013 to 8.2% (95% CI 7.0-9.6) in 2014. Monthly or more use of e-cigarettes increased from 0.9% (95% CI 0.5-1.5) to 1.7 (1.2-2.4), but remained rare in never-smokers at under 0.2%. The proportion of young people who perceived e-cigarettes to be less harmful to users than cigarettes fell from 73.4% (95% CI 71.0-75.8) to 66.9% (95% CI 64.5-69.2), while the proportion who considered e-cigarettes to cause similar levels of harm increased from 11.8% (95% CI 10.0-13.5) to 18.2% (95% CI 16.3-20.1). Of the 8.2% of e-cigarette ever-users in 2014, 69.8% (95% CI 62.2%-77.3%) had smoked a cigarette prior to using an e-cigarette, while 8.2% (95% CI 4.1%-12.2%) first smoked a cigarette after e-cigarette use. CONCLUSIONS: A growing proportion of young people in Great Britain believe e-cigarettes are as harmful as smoking tobacco. Use of e-cigarettes by young people is increasing, but is largely confined to those who smoke.

Motivational interviewing for HIV risk reduction among gay men in commercial and public sex settings.

The present paper addresses the feasibility of combining motivational interviewing and cognitive interventions to HIV risk reduction in commercial venues and public sex environments (PSEs). The logic for these two approaches is considered and an intervention combining key elements of the two is presented. The intervention uses a questionnaire format to encourage individuals to compare their desired versus actual behaviour (i.e. chosen personal risk reduction strategy versus 'slip-ups'/unwanted risk taking), and to recognize their risk-related cognitions. High-risk individuals are identified, and health-focused conversations developed from the brief schedule. The structure and key design issues in the development of a feasible, acceptable and evidence-based tool are reviewed. The limitations of more complex, focused interventions in the context of commercial and PSE settings are discussed.
