Understanding Alcohol and Tobacco Consumption in Asexual Samples: A Mixed-Methods Approach.

Existing research suggests significant differences in alcohol and tobacco consumption trends according to one's sexual orientation. However, asexual people have not yet been included in these comparisons. In this mixed-methods, two-part study, we sought to compare group differences in alcohol and tobacco consumption among sexual orientations, focusing on asexual people, sexual people, and those in the "gray" area between asexual and sexual (i.e., "gray-asexual"). Data for Study 1 came from four British studies: National Surveys of Sexual Attitude and Lifestyles I, II, and III in 1990, 2000, and 2010 (NATSAL I, II, III) and Towards Better Sexual Health (TBSH) in 2000. Sample sizes for each study by gender are: NATSAL I-M: 1923 F: 3511; NATSAL II-M: 4604 F: 6031; NATSAL III-M: 6122 F: 7966; TBSH-M: 347 F: 552. Notably, asexual and gray-asexual respondents were found to consume significantly less alcohol and were more likely to abstain from drinking alcohol altogether, compared to allosexual respondents. Differences in tobacco consumption were only statistically significant for asexual respondents in two of three studies that included tobacco consumption. Each of the four studies also found that asexual and gray-asexual respondents were more likely to be non-drinkers (40.0-77.8%, asexual and 28.1-50.1% gray-asexual, non-drinkers, respectively) than allosexual respondents (10.2-27.2%, non-drinkers). Interviews conducted in Study 2 identified somatic, social, and psychological experiences and motivations that may shed light on the reasons for lower drinking frequencies among asexual individuals. Variability in alcohol consumption levels among asexual, lesbian, gay, and bisexual respondents, and the general population raises new questions about the motivations for why people consume alcohol.
