1.  Out smoking on the big screen: Tobacco use in LGBT movies, 2000–2011 
Tobacco control  2013;23(0):e156-e158.
Objective
Lesbian, gay, bisexual, and transgender (LGBT) people have significantly higher smoking prevalence than heterosexual people in the United States. The reasons for this disparity remain unclear. Tobacco use in movies has a substantial influence on tobacco use behaviours, particularly among youth. Yet, no research has examined tobacco use in movies for LGBT audiences or containing LGBT characters.
Methods
We identified 81 U.S. movies from 2000–2011 with a theatre release and with LGBT themes or characters. We then selected a random sample of these movies (n = 45) for quantitative content analysis to examine the proportion of movies with depictions of tobacco use and the number of occurrences of tobacco use.
Results
Tobacco use was depicted in 87%(95% confidence interval [CI]: 80%–94%) of movies with an average of 4 occurrences of tobacco use per hour (95% CI: 3–5). Only 15% (95% CI: 8%–23%) of movies and 3% of all depictions of tobacco use conveyed any harms of tobacco use.
Conclusions
Viewers of movies with LGBT themes or characters are exposed, on average, to one depiction of tobacco use for every 15 minutes of movie run-time. As a major component of the entertainment media environment, movies may contribute to smoking among LGBT people.

2.  A systematic review of the aetiology of tobacco disparities for sexual minorities 
Tobacco control  2011;22(2):66-73.
Objective
To conduct a systematic review of the literature examining risk factors/correlates of cigarette smoking among lesbian, gay and bisexual (ie, sexual minority) populations.
Methods
Sets of terms relevant to sexual minority populations and cigarette smoking were used in a simultaneous search of 10 databases through EBSCOhost. The search was limited to the peer-reviewed literature up to January 2011, using no geographic or language limits. For inclusion, the paper was required to: (1) have been written in English, (2) have sexual minorities (defined by either attraction, behaviour, or identity) included in the study population and (3) have examined some form of magnitude of association for risk factors/correlates of any definition of cigarette smoking. A total of 386 abstracts were reviewed independently, with 26 papers meeting all inclusion criteria. Abstracts were reviewed and coded independently by authors JB and JGLL using nine codes derived from the inclusion/exclusion criteria.
Results
Studies used various measures of sexual orientation and of smoking. Risk factors that could be considered unique to sexual minorities included internalised homophobia and reactions to disclosure of sexual orientation. Some studies also indicated common smoking risk factors experienced at higher rates among sexual minorities, including stress, depression, alcohol use and victimisation.
Conclusions
This review identified risks that were associated with sexual minority status and common to the general population but experienced at potentially higher rates by sexual minorities. Government and foundation funds should be directed towards research on the origins of this disparity.
