Surveys of lesbians that did not have heterosexual control groups have raised the possibility that morbidity is greater among lesbians than among heterosexual women: lesbians have a higher rate of nulliparity and late parity

Added to these risk factors is the possibility that lesbians and bisexual women use the healthcare system less often than heterosexual women and then only after they have had more severe symptoms.

Additionally, lesbians and bisexual women may avoid the healthcare system because they fear or have experienced discrimination because of their sexual orientation.

These factors may adversely affect the health of lesbians and bisexual women. Previous surveys have used convenience samples from outside the healthcare setting without comparison groups of heterosexuals. The Institute of Medicine at the National Academy of Science found that more data are needed to determine if lesbians are at higher risk of developing some health problems.
21 To explore the use of preventive health measures among lesbians already using the healthcare system, data were collected on lesbian, bisexual, and heterosexual adult women who used outpatient services and analyzed according to the sexual orientation of the patient.
