摘要
To determine the prevalence and predictors of cervical squamous intraepithelial lesions (SIL) among HIV-infected women in Tanzania, a cross-sectional study was conducted among HIV-infected women at HIV care and treatment clinics. A Papanicolaou (Pap) smear was used as a screening tool for detection of cervical SIL. From December 2006 to August 2009, 1365 HIV-infected women received cervical screening. The median age was 35 (interquartile range [IQR]: 30-42) years, and the median CD4+cell count was 164 (IQR: 80-257) cells/mm(3). The prevalence of cervical SIL was 8.7% (119/1365). In multivariate analysis, older age (50 versus 30-<40 years: prevalence ratio [PR], 2.36; 95% confidence interval [CI], 1.45-3.84, p for trend=0.001), lower CD4+cell counts (<100 versus 200cells/mm(3): PR, 1.55; 95% CI, 1.01-2.36, p for trend=0.03) and cervical inflammation (PR, 1.73; 95% CI, 1.16-2.60, p=0.008) were associated with an increased risk of cervical SIL. Women with advanced WHO HIV disease stage (IV versus I/II: PR, 3.45; 95% CI, 1.35-8.85, p for trend=0.01) had an increased risk for high-grade SIL. In resource-limited settings where it is not feasible to provide cervical cancer prevention services to all HIV-infected women, greater efforts should focus on scaling-up services among those who are older than 50 years, with lower CD4 cell counts and advanced HIV disease stage.
