Mathematical procedures

For the following analyses, “people HPV” refers to seropositivity otherwise DNA positivity for around one of the second Hour-HPV systems: 16, 18, 30, 33, 35, forty-five, 52, and you may 58.

Any, type-specific and age-specific ( < 20,>=61 years) HR-HPV seroprevalence (at baseline and follow-up), seropersistence, seroclearance and seroconversion (at follow-up) were assessed. Seropersistence was defined as the number of women who were seropositive at baseline and follow-up among all women who were seropositive at baseline. Seroclearance was the number of women who were seropositive at baseline and seronegative at follow-up among all those seropositive at baseline.

Standard seropositivity is weighed against concurrent cervical DNA positivity to assess concordance, which can only be checked out at kind of-certain height, because the women are often contaminated with several type of HPV and you will the fresh new Cultura dominicana namoro masculino menina regras concordance position is going to be additional for every type of. To conquer instance restriction, analyses were did on genotype top using general estimating equation (GEE) designs that be the cause of the possible lack of independence anywhere between numerous observations from the same lady [twenty-two, 23].

Univariable and multivariable GEE models were performed to identify predictors of HR-HPV seroprevalence at baseline. Risk estimates were adjusted by potential risk factors for HPV seropositivity: age at baseline, marital status, education level, number of children, age at first sexual intercourse, lifetime number of sexual partners, high-risk sexual partner (who engaged in extra-relationship sexual activity), history of sexually transmitted disease, hormonal contraception, smoking, condom use and cervical HR-HPV DNA infection.
