Cancer-related risk indicators and preventive screening behaviors among lesbians and bisexual women

Objectives. This study examined whether lesbians are at increased risk for certain cancers as a result of an accumulation of behavioral risk factors a nd difficulties in accessing health care. Methods. Prevalence estimates of behavioral risk factors (nulliparity, obes ity, smoking, and alcohol use), cancer screening behaviors, and self-report ed breast cancer histories derived from 7 independently conducted surveys o f lesbians/bisexual women (n = 11876) were compared with national estimates for women. Results. In comparison with adjusted estimates for the US female population , lesbians/bisexual women exhibited greater prevalence rates of obesity, al cohol use, and tobacco use and lower rates of parity and birth control pill use. These women were also less likely to have health insurance coverage o r to have had a recent pelvic examination or mammogram. Self-reported histo ries of breast cancer, however, did not differ from adjusted US female popu lation estimates. Conclusions. Lesbians and bisexual women differ from heterosexual women in patterns of health risk. These women would be expected to be at especially greater risk for chronic diseases linked to smoking and obesity.
