The predictors for CIN among HIV infected women were the number of life time sexual partners (Adjusted OR 4.06; 95% CI 1.86-8.88, P<0.001), a history of genital warts (Adjusted OR 16.6; 95% CI5.91- 47.0, P<0.001), a history of STI (Adjusted OR 7.39; 95% CI 1.67-33.66, P=0.010) and a baseline CD4 lymphocytes count of less than 200cells/mm3 (Adjusted OR 2.71; 95% CI 01.24-5.90, P=0.012) [ See Table 5]. This evidence concerns the gene CD4 and anogenital human papillomavirus infection.
