Tobacco control efforts targeting the LGB population are needed to reduce this group's high rate of cigarette smoking.

This study aims to investigate the association between prenatal exposure to terbutaline and other β2 adrenergic receptor (B2AR) agonists and autism spectrum disorders (ASDs). The methodology used is a case–control study among children born from 1995 to 1999 at Kaiser Permanente Northern California hospitals. Cases (n = 291) were children with an ASD diagnosis; controls (n = 284) were children without ASDs, randomly sampled and frequency-matched to cases on sex, birth year, and delivery hospital. Exposure to B2AR agonists during 30 days prior to conception and each trimester of pregnancy was ascertained from prenatal medical records and health plan databases. The frequency of exposure to any B2AR agonist during pregnancy was similar for mothers of children with ASD and mothers of controls (18.9% vs. 14.8%, P = 0.19). Exposure to B2AR agonists other than terbutaline was not associated with an increased risk for ASDs. However, terbutaline exposure for >2 days during the third trimester was associated with more than a fourfold increased risk for ASDs independent of indication although the limited sample size resulted in an imprecise and nonsignificant effect estimate (ORadj = 4.4; 95% confidence interval, 0.8–24.6). This analysis does not offer evidence linking B2AR exposure in pregnancy with autism risk. However, exposure to terbutaline during the third trimester for >2 days may be associated with an increased risk of autism. Should this result be confirmed in larger samples, it would point to late pregnancy as an etiologic window of interest in autism risk factor research.

Large population-based studies of alternative tobacco use in the lesbian, gay, and bisexual (LGB) population are needed to more fully measure tobacco use outcomes. This descriptive study used standard measures of alternative tobacco use from two separate, statewide household-based studies to compare basic prevalence rates in the LGB population and the general population in California. A total of 1,950 adult lesbians, bisexual women, heterosexual women who have sex with women, gay men, bisexual men, and heterosexual men who have sex with men, all living in California, completed surveys between 2003 and 2004. From a general population-based sample (California Tobacco Survey, 2002), a total of 11,037 adult women and 9,488 men were used as comparisons. The prevalence rates for lifetime and current cigar smoking and smokeless tobacco use were lower for all LGB subpopulations compared with the general population.
