Sexual orientation and related viral sexually transmitted disease rates among US women aged 15 to 44 years.

I used data from the 2002 National Survey of Family Growth to measure sexual orientation and viral sexually transmitted disease (STD) rates among US women aged 15 to 44 years. Sexual behavior and sexual identity data indicated that 1.3% to 1.9% of the women were lesbians and 3.1% to 4.8% were bisexual. Self-reported viral STD rates were significantly higher among bisexual women (15.0% to 17.2%) than among lesbians (2.3% to 6.7%). These findings support the need for STD prevention interventions that consider lesbians and bisexual women separately.
