A recently published study assessed associations between social support and DSM-5 tobacco use disorder by sex and sexual minority identity. Tobacco related findings included:

• Sexual minority adults had higher odds of tobacco use disorder compared to heterosexual adults.
• Sexual minority women experienced the highest proportion of tobacco use disorder.
• Higher social provision was associated with lower rates of tobacco use disorder.
• Compared to heterosexual adults, sexual minority women with at least one child under the age of 18 had higher odds of tobacco use disorder.

The researchers concluded that there are significant associations between functional support (quality or provision of support) and structural support (type and frequency of social networks) and tobacco use disorder which differ by sex and sexual identity status.
