Filter by:PROJECT JUSTIFICATION: Cervical cancer is a serious public health problem in Brazil, and is the cause of significant morbidity and mortality among Brazilian women. In spite of government efforts to improve the coverage rates of Pap tests, the disease-related incidence and mortality rates remain high and the diagnosis is still too late.Considering that the chronic human papillomavirus (HPV) related genital infection leads to cervical cancer development, cervical cancer should be the target of primary prevention through vaccination. PROJECT OBJECTIVES: This project aims to evaluate de following vaccination indicators: 1) Program acceptance rate; 2) Vaccine coverage rate; 3) Three-dose completion rate; 4) Rescue vaccination demand; 5) Adverse event rate; TARGET POPULATION: Schoolgirls attending the 6th and 7th grades of elementary school (mean age = 11.9 yo). VACCINATION PROGRAM: The program adopted the quadrivalent vaccine because it is considered superior to the bivalent vaccine in preventing HPV-induced lesions. In addition to preventing the development of pre-cancer lesions and cervical cancer, the quadrivalent vaccine has also proved to be effective in preventing condyloma, and vaginal and vulvar cancer. The girls received the vaccines doses at their schools (school-based program) and also at the Barretos Cancer Hospital. RESULTS: Program acceptance rate = 91.8% (95%CI: 87.0%-96.8%); Vaccine coverage for 1st, 2nd and 3rd doses = 87.5% (95%CI: 82.9%-92.2%), 86.3% (95%CI: 81.8%-91.1%) and 85.0% (95%CI: 80.5%-89.7%). Three dose completion rate = 97.2% (95%CI: 92.0%-100.0%). Reasons for dropping out of the vaccination program included: moving out of town (17), lost during follow up (16), guardians' decision but without a reasonable justification (3), girl refused to continue in the program (1) and pregnancy (2). Two girls interrupted the vaccination because of adverse events reported by the parents. Rescue vaccination demand = 279 girls on the first dose (20.3%; 95%CI: 17.9%-22.8%), 357 on the second dose (26.3%; 95%CI=23.6%-29.1%) and 291 on the third dose (21.7%; 95%CI=19.3%-24.4%). Thirty adverse events were recorded or observed in 4,074 doses, providing an adverse event rate of 0.7% (95%CI: 0.5%-1.1%). There was no severe adverse event.
The goal of this study is to determine whether a two-page print brochure that delivers individually tailored educational messages about the Human papillomavirus (HPV) vaccine increases HPV vaccine-hesitant mothers' intentions to have their adolescent daughters vaccinated against HPV.
This study will focus on the primary objectives: - To estimate the prevalence of HPV vaccination among a large cohort of childhood cancer survivors and an acquaintance control group. - To describe the difference in HPV vaccination rate and HPV vaccination intent among preadolescent/adolescent females surviving childhood cancer and an acquaintance control group. This study will also focus on the secondary objectives: - To examine sociodemographic, medical, and psychological differences between those who have/have not initiated HPV vaccination and between those who do/do not intend to get vaccinated in the future. - To assess the general predictive influence of sociodemographic, medical, and psychological variables on HPV vaccination and intent among mothers with preadolescent/adolescent daughters.
Background: - The Mississippi Delta (which includes the counties along the Mississippi River) is one of the poorest areas in the United States. Women living in the Mississippi Delta have disproportionately high rates of cervical cancer, but they are unlikely to come to clinics except perhaps for giving birth, years before they are diagnosed with cancer. - To improve rates of screening, researchers are attempting an outreach study to see whether under-screened women, if approached by door-to-door recruitment, would get screened by one of two methods (home-based self-collection and testing, or a clinic exam) and which method they would prefer. Objectives: - To assess/measure increased participation of under-screened women living in the Mississippi Delta in cervical cancer screening by offering women the opportunity to get screened by one of two possible community outreach-based cervical cancer screening modalities, self-collection and HPV testing or clinic-based cytology screening, the current standard of care. Eligibility: - Women between 26 and 65 years of age, who are not pregnant currently or in the past 8 weeks, have an intact cervix, have no history of cancer, and have not been screened for cervical cancer in the past 3 years. Design: - Researchers will recruit participants on a door-to-door basis. Researchers will recruit all eligible women within a household. Recruitment will be done only during daylight hours but at the end of the working day to maximize the chances of finding women at home. - Eligible women willing to participate will complete a questionnaire with demographic and medical information. - Participants will be asked to choose the screening method of their preference. If they choose self-collection with HPV testing, they will be given a self-collection kit and asked to perform the self-collection and return the kit within 1 month. Participants who choose to have cytology screening will be provided with the phone number and location of the local health department clinic and will be encouraged to schedule their screening within the following month. - Women who do not complete their participation within 1 month will be considered noncompliant with their chosen intervention. Researchers will re-contact noncompliant women to offer them participation in the study, including permitting them to refuse to participate or to choose the alternative intervention....
African American women living in the rural South are twice as likely as Caucasian women to develop cervical cancer and die of invasive cervical cancer at a higher rate than any other racial/ethnic group in the US (1). Reasons for low HPV vaccination rates among rural African Americans are not well understood. HPV vaccination compliance is likely influenced by barriers to health care access, misinformation regarding vaccinations, religious beliefs related to sexual health and behaviors, and mistrust of the medical community (2, 3). Because the vaccination of minors requires primary caregiver consent, vaccination commitment and compliance is strongly influenced by family beliefs and communication regarding health and sexuality. To date, little research has examined the cultural, familial, and intrapersonal influences on HPV vaccination compliance among rural African American women. This study will address these gaps in the literature and provide data needed to develop effective interventions and health promotion materials to encourage HPV vaccination among rural African American women. From a pool of approximately 800 families who are participating in ongoing longitudinal research through the Center for Family Research at the University of Georgia, the investigators will recruit 200 rural female African American youth aged 13-17 who have not received the HPV vaccine and their primary caregivers (n=200) into an observational, prospective study on vaccination commitment and compliance. The investigators hypotheses are as follows: 1. Sociocultural factors that rural African Americans experience, including discrimination, previous health care experience, religious beliefs, and community norms regarding HPV vaccination and adolescent sexual behavior, will forecast primary caregivers' HPV vaccination commitment and compliance for their daughters. The investigators also predict that primary caregivers' HPV-related knowledge and attitudes will mediate this association. 2. Sociocultural factors will influence sexual health-related family communication and interaction, primary caregivers' and youths' HPV-related attitudes, and HPV vaccination commitment and compliance. 3. Primary caregivers' attitudes, youths' attitudes, and family health communication will contribute to youths' and caregivers' vaccination commitment and compliance. 4. Youths' sexual behavior will influence their attitudes, family health communication, and vaccination commitment and compliance.
The purpose of this study is to learn about the natural history of Human Papillomavirus (HPV) infection in men. The study will also find out what factors are linked to HPV in men including other sexually transmitted diseases (STDs). If participants test positive for syphilis, gonorrhea or chlamydia, we are required by law to report the results to the Florida Department of Health. Participants will be able to get free medical treatment from the Florida Department of Health for these STDs. Participants will be given a written report of the results of the STD testing.
The aims of this study are: 1. Surveillance of the prevalence of HPV infection in ASCUS, AGCUS and SIL cases pooled from medical centers in Taiwan and analysis of the related epidemiological factors. 2. Providing a better understanding of the natural history of HPV infection with its correlation with pathologic changes through a longitudinal follow-up of LSIL cases.
