Prevalence of bacterial vaginosis in women attending one of three general practices for routine cervical cytology.

A prospective observational study of asymptomatic women from three different general practices was set up to establish the incidence of bacterial vaginosis (BV). The study group comprised 287 women recalled to their general practitioner's surgery for routine cervical smears. The prevalence of an abnormal vaginal flora was about the same in women attending the 3 practices. Nearly 14% of women had abnormal vaginal flora and about 9% had BV on gram stain examination of vaginal secretions. This was 2-3 times more common than findings consistent with vaginal candidiasis (3.8%). Significant numbers of women with BV had received antifungal therapy suggesting a misdiagnosis. Because of its potential complications, women should be offered screening for BV in a well-women setting and, if found, should be treated if symptomatic or at risk of adverse obstetric or gynaecological sequelae.
