This study presents a case-control nested analysis of cervical squamous intraepithelial lesions (SIL) in a cohort of 423 HIV-infected women with registered Pap smears between 1991 and 2004. Data on Pap smear results, CDC HIV classification, CD4 cell count and antiretroviral therapy were prospectively collected. Pap smears were classified using the Bethesda classification. Women had a median of three Pap smears registered in the database. The first Pap smear was registered 相似文献

OBJECTIVE: To determine the feasibility of cervical cancer screening in an urgent care clinic. DESIGN: Prospective randomized trial. SETTING: Public teaching hospital. PATIENTS: Women presenting to the urgent care clinic whose evaluation necessitated a pelvic examination were eligible for participation. Women who had a hysterectomy, had a documented Pap test at our institution in the past year, did not speak English or Spanish, or had significant vaginal bleeding were excluded. Women presenting to the gynecology clinic for a scheduled Pap test were used as a comparison group for rates of follow-up, Pap smear adequacy, and Pap smear abnormalities. INTERVENTIONS: Women randomized to the intervention group had a Pap test performed as part of their pelvic examination, while women in the usual care group were encouraged to schedule an appointment in the gynecology clinic at a later date. The women in the two groups completed identical questionnaires regarding cervical cancer risk factors and demographic information. MEASUREMENTS AND MAIN RESULTS: Ninety-four (84.7%) of 111 women in the intervention group received a Pap test, as compared with 25 (29%) of 86 in the usual care group (P<.01). However, only 5 (24%) of 21 women with abnormal Pap smears in the intervention group received follow-up compared with 6 (60%) of 10 women seen during the same time period in the gynecology clinic for self-referred, routine annual examinations (P=.11). Pap smears obtained in the urgent care clinic were similar to those in the gynecology clinic with regard to abnormality rate (22.3% vs 20%; P=.75, respectively) and specimen adequacy (67% vs 72%; P=.54, respectively). CONCLUSIONS: Urgent care clinic visits can be used as opportunities to perform Pap test screening in women who are unlikely to adhere to cervical cancer screening recommendations. However, to accure the full potential benefit from this intervention, an improved process to ensure patient follow-up must be developed. Presented at the Society of General Internal Medicine annual meeting, San Francisco, Calif, May 1, 1999 Funding for this research was provided by the Division of General Internal Medicine, University of Colorado Health Sciences Center.  相似文献

This study was undertaken to determine the prevalence of self-disclosure of HIV status among the postparturient HIV-infected women and to describe the correlates of disclosure in this population. Subjects for this study include all known HIV-infected postparturient women in Barbados who delivered during 1997 through 2004. Sociodemographic data are routinely collected from all HIV-infected postparturient women. Data on disclosure were collected through one-to-one interview of the consenting women included in this study. One hundred thirtynine women were studied. Forty women (28.8%) had self-disclosed their HIV status to other people including their current sex partner. Among women who did not disclose their HIV status to anybody, 30 (30%) gave fear of stigmatization as the reason for nondisclosure, while 23 (23%) did not disclose their status as they feared abnormal reaction from their current sex partner and possible violence directed at them. Women who had disclosed their HIV status were more likely to use condoms during all sexual encounters, less likely to have had subsequent pregnancy from a different sex partner, were more likely to have a partner who had been tested for HIV, and were themselves more likely to be attending the centralized HIV clinic for follow-up and care compared to those who did not disclose. A substantial proportion of HIV-infected postparturient women never disclosed their result to a partner or a close relative. Lack of disclosure may have limited their ability to engage in preventive behaviors or to obtain the necessary emotional support for coping with their serostatus or illness.  相似文献

Significantly elevated rates of cervical cancer and low rates of Papanicolaou (Pap) smear screening have been documented among HIV-infected women. However, little is known about women's perceptions of cervical cancer screening utilization. Hence, this study describes barriers and facilitators related to cervical cancer screening in a sample of HIV-infected women seeking care at an integrated HIV clinic in Houston, Texas. Using an inductive qualitative methodological approach, data were obtained from five focus group discussions with a total of 33, HIV-infected women. The majority of the study sample consisted of women who self-identified as Black (69.7%), and reported heterosexual contact as the mode of HIV acquisition (75.8%). Barriers to cervical cancer screening were described as pain and discomfort associated with receiving Pap smears and subsequent procedures; lack of awareness of cervical cancer as a preventable disease; limited transportation access; and systemic issues as it relates to scheduling gynecological appointments. Facilitators were described as awareness of HIV-infected women's increased risk of cervical cancer and strong provider–patient relationships. To address disparities in cervical cancer screening among low-income HIV-infected women, programs should capitalize on the identified facilitators and alleviate modifiable barriers using multilevel strategies.  相似文献

Very little is currently known about factors impacting the prevalence of cervical cancer screening among women living with HIV-AIDS (WLHA). To better understand this issue, we surveyed low-income, medically underserved women receiving subsidized gynecologic care through an integrated HIV clinic. A self-administered questionnaire was completed by 209 women who self-identified as HIV positive. A total of 179 subjects (85.7%) reported having had a Pap test in the last three years. The majority of WLHA (95%) knew that the Pap test screens for cervical cancer. However, overall knowledge of cervical cancer risk factors, such as multiple sexual partners or sex with a man with multiple partners, was low (43% and 35%, respectively). Unscreened women were younger and more likely to be single with multiple current sexual partners. In multivariable analyses, the only factors associated with Pap testing were a woman's perception that her partner wants her to receive regular screening (aOR 4.64; 95% CI: 1.15–23.76; p?=?.04), number of clinic visits during the past year (aOR 1.36, 95% CI: 1.05–1.94; p?=?.04) and knowledge that the need for a Pap test does not depend on whether or not a woman is experiencing vaginal bleeding (aOR 6.52, 95% CI: 1.04–49.71; p?=?.05). We conclude that support from male partners in addition to effective contact with the health system and knowledge of cervical cancer risk factors influence Pap utilization among low-income WLHA. Future measures to improve the care for this population should increase knowledge of cervical cancer risk factors and encourage social support for cervical cancer screening among WLHA.  相似文献

Female STD clinic clients were categorized by report of sex partners' gender in the preceding 2 months and characterized with respect to HIV risk and STD diagnosis. Among 18,585 visits, 290 women (1.5%) reported sex exclusively with women, and 841 (4.5%) reported sex with both men and women. Relative to women reporting sex only with men, those reporting sex with both men and women reported more recent partners, sex with partners at high risk for HIV, injection drug and crack cocaine use, and exchange of sex for drugs or money. Women reporting sex exclusively with women more frequently reported prior sex with a bisexual man or an HIV-infected partner. Female STD clinic clients who report sex with both men and women may be at increased HIV risk relative to women reporting sex exclusively with men, and women who report sex only with women may be more likely to have had sex with men at high risk for HIV infection.  相似文献

The objective of this study was to estimate HIV disclosure rates and identify factors that predict non-disclosure in Thai women who tested HIV positive during pregnancy or at delivery. This was a cohort study evaluating the implementation of prevention of mother-to-child HIV transmission programs at two Bangkok hospitals in 1999-2003. All HIV-infected women who delivered during the study period were enrollment eligible. Thai-language questionnaires were used to collect baseline data before discharge from the hospital. At the 1 and 4 month follow-up visits, women were asked if they had disclosed their HIV status. Of the 799 women who enrolled, 647 (81.0%) completed follow-up at 1 and 4 months. Four hundred fifty-three (70.0%) women disclosed their status by 1 month. Of the 194 women who had not disclosed by 1 month, 48 (24.7%) had disclosed their status by 4 months. An independent increased odds of non-disclosure by 1 month was associated with not having a partner tested for HIV (OR=5.83, 95% CI=3.19-9.08) or not knowing if the partner was ever tested for HIV (OR=1 3.02, 95% Cl=5.26-32.28), first learning of HIV positive status during delivery (OR=6.84, 95% CI=2.36-19.81) or after delivery (OR=3.14, 95% CI=1.57-6.26) and having >2 lifetime sexual partners (OR=1.71, 95% CI=1.04-2.82). Not living with a partner every day was associated with non-disclosure by 4 months in those women who had not disclosed by 1 month (OR=2.28, 95% CI=1.43-3.64). Despite high rates of disclosure by 1 month, 22.6% of women still had not disclosed their HIV status to their partners by 4 months. The benefits of disclosure warrant effective interventions targeted at women at risk for non-disclosure.  相似文献

Current guidelines call for Papanicolaou (Pap) smear screening of HIV-infected women at least annually. After the initiation of a weekly computer based Pap smear reminder list in an HIV care clinic, the prevalence of scheduled women with up-to-date Pap smears was calculated for the one-year project period and was compared to the prevalence preceding the project. The prevalence of scheduled women with up-to-date Pap smears increased from 61.4% to 73.2% (P <0.001) during the project period. Including Pap smears that were performed elsewhere, the final up-to-date Pap smear rate was 82.7%. The improved rate of up-to-date Pap smears showed no sign of attenuation over time. A computerized report generated from data in the hospital information system increased rates of compliance with Pap smear screening recommendations. Creative utilization of hospital data environments may be an inexpensive route to improved compliance with practice guidelines.  相似文献

The prevalence of cervical intraepithelial neoplasia (CIN) is high among HIV-infected women. Decreased CD4 lymphocytes, high human immunodeficiency viral load (HIVL) and human papillomavirus (HPV) infection are risk factors for CIN. We characterized the prevalence, risk factors and prognosis of histologically-verified CIN among systematically followed HIV-infected women enrolled from a low HIV-prevalence population. The study population comprised 153 HIV-infected women followed between 1989 and 2006. The mean +/- SD duration of follow-up was 5.6 +/- 3.8 years. Demographic as well as treatment-related data were derived from medical reports. During the follow-up, 51 subjects (33%) displayed CIN (16% CIN 1 and 18% CIN 2 +), whereas 102 subjects had Pap smear results of normal cells, atypical squamous cells of uncertain significance, or signs of low-grade squamous intraepithelial lesion (LSIL) but no CIN in histological specimens from the cervix. Only one case of cancer of the uterine cervix was detected. Pap smears were reliable in screening for CIN; 75% of patients with CIN had high-grade squamous intraepithelial lesion (HSIL) or LSIL in Pap smears taken at the time of dysplasia. The incidence of CIN decreased from 12.7 to 3.5 (per 100 subjects) between 2000 and 2005 (P = 0.07). The risk of CIN was not associated with decreased levels of CD4 lymphocytes, duration of HIV infection, use of antiretroviral medication or plasma HIVL. In univariate analysis, bacterial vaginosis (BV) was associated with a significantly increased risk of CIN, whereas parity was associated with lower risk of CIN. Each delivery lowered the risk of CIN by 30% (P = 0.02). The significantly lower risk of CIN among parous women (P = 0.04) persisted in multivariate analysis. CIN was treated by means of loop electrosurgical excision procedure (LEEP), (n = 34). The recurrence rate was low; seven subjects (14%) had a recurrence of CIN during follow-up. The nadir of CD4 lymphocytes was lower (P = 0.04) and the HIVL higher (P = 0.03) among subjects with recurrence of CIN. Duration of HIV infection, use of antiretroviral medication and positive margins in LEEP specimens were indistinguishable among subjects with vs. without recurrence of CIN. The prevalence of CIN is high among systematically managed HIV-infected women. However, the incidence of CIN decreased during the 21st century. BV was associated with an increased risk of CIN whereas parous women had lower risk of CIN. However, the patients with and without CIN could not be distinguished on the basis of previously described risk factors. Regular follow-up by means of Pap smears is warranted in all HIV-infected women.  相似文献

We report a study of women 15-49 years aimed at assessing correlates of HIV testing and having received test results in a nationally representative survey of women in Malawi. A total of 26 259 women were recruited into the study, of whom 3712 (14.1%) had ever been tested for HIV infection and received their results. We found that age and education were not significantly associated with HIV testing but marital status, wealth, region were. Contrary to our expectations that women who had delivered a child were more likely to have been ever tested when accessing prenatal and intra-partum care, we found that women who had delivered a child in the 2 years before the survey were less likely to have ever been tested. We suggest that by 2006 when the survey was conducted, prenatal and intra-partum care were not important avenues for HIV testing in Malawi.  相似文献

Factors affecting the eligibility and acceptability of voluntary counselling and rapid HIV testing (VCT) were examined among pregnant women presenting in labour in Pune, India. Of the 6702 total women appearing at the delivery room from April 2001 to March 2002, 4638 (69%) were admitted for normal delivery. The remaining women presented with obstetrical complications, delivered immediately or were detected to be in false labour. Overall, 2818 (61%) of the admitted women had been previously tested for HIV during their pregnancy. If previously seen in the hospital's affiliated antenatal clinic, the likelihood of being previously tested was 89%, in contrast to 27% of women having prenatal care elsewhere. Of the admitted women, 3436 (74.3%) were assessed for their eligibility for rapid HIV VCT in the delivery room. Only 1322 (38%) of these women were found to be in early labour and without severe pain or complications, and therefore eligible for rapid HIV screening in the delivery room (DR). Of those 1322 eligible women, only 582 (44%) consented and were tested for HIV, of whom nine (1.6%) were found to be HIV-infected. Of the 1674 women arriving in the DR with no evidence of previous HIV testing, through this DR screening programme, we identified four women with HIV who could now benefit from treatment with ART. Given the high rates of HIV testing in the antenatal clinic at this site and the challenges inherent to conducting DR screening, alternatives such as post-partum testing should be considered to help reduce maternal to infant transmission in this population.  相似文献

We examined factors associated with perceived risk of AIDS, behavior change, and HIV infection in a representative sample of 1458 child-bearing urban women in Rwanda, central Africa. Although 68% of women reported only one lifetime partner, and the majority (87%) lived with a husband or steady partner, the prevalence of HIV antibodies was still high (32%). Before receiving their HIV test results, the women completed a questionnaire about AIDS knowledge, attitudes, and practices. Knowledge about HIV transmission was high, with 96-98% of women correctly identifying the three primary routes of infection. However, only 16% of women reported taking any action to avoid AIDS in the previous year, and most (11%) had done so merely by asking their male partners to change their behavior. Only 7% of women had ever tried condoms, and many (68%) thought they could be dangerous to use. Women who perceived themselves at risk of AIDS (57%) were more likely to report changing behavior; they were also more likely to be infected with HIV. Other factors associated with behavior change included having known someone with AIDS, having discussed AIDS with a male partner, and believing that condoms are not dangerous. Future interventions should enhance perception of risk, encourage male sexual partners to reduce risky behavior, and increase familiarity with condoms.  相似文献

Intimate partner violence (IPV) has been shown to be associated with higher rates of HIV infection among women, underscoring the importance of encouraging IPV victims to receive HIV testing. However, we do not know how much HIV testing behavior is influenced by IPV victimization. The current study characterized the association between individual types of IPV and HIV testing in a large sample of non-pregnant women in 15 US states/territories. The 2005 Behavioral Risk Factor Surveillance System data were analyzed after restricting the sample to non-pregnant women. The dependent variable, whether a woman ever had an HIV test, was examined in relation to individual types of IPV victimization (threatened physical violence; attempted physical violence; completed physical violence; and unwanted sex). Associations between HIV testing and types of IPV were assessed using adjusted risk ratios (aRR) that controlled for demographics and HIV-related risk factors (intravenous drug use, sexually transmitted diseases, exchange sex, unprotected anal sex). Approximately 28.6 % of women reported ever having experienced IPV, and 52.8 % of these women reported being tested for HIV. Among women who had not experienced IPV, 32.9 % reported ever having been tested for HIV. HIV testing was associated with lifetime experience of threatened violence (aRR = 1.43; 95 % CI = 1.24?1.65), attempted violence (aRR = 1.43; 95 % CI = 1.20?1.69), completed physical violence (aRR = 1.30; 95 % CI = 1.13?1.48), and unwanted sex (aRR = 1.66; 95 % CI = 1.48?1.86). Women who experienced each type of IPV were more likely to have been ever tested for HIV compared to women with no IPV history. However, nearly half of those reporting IPV, even though at greater risk for HIV infection, had never been tested. Additional efforts are needed to address barriers to testing in this group.  相似文献

Despite 15 years of prevention efforts, recent increases in HIV infection have been documented for Black women in the US. Little is known about the role played by HIV status disclosure in high HIV prevalence communities. 180 Black women who used drugs in the past 30 days were recruited between May 2002 and May 2004 in New York City. Women were administered a structured network questionnaire and HIV serotested. Risk practices, HIV status disclosure within networks and mixing patterns by known HIV status are examined. Most (85%) women had used crack in the past 30 days; 48 (27%) had injected drugs, 65 (36%) reported anal sex, and 99 (55%) reported sex work at some time. Forty (22%) women were HIV-seropositive; 29 (16%) knew their seropositive status. Of high risk individual behaviours, only a history of sex work was associated with an HIV-seropositive status [(aOR=3.0; 95%CI: 1.3-7.3), p=.01]. Few (7%) of 600 network members disclosed an HIV positive status, although 73% were sex or drug use partners. Women who knew themselves to be HIV-infected were more likely than other women to report HIV-infected network members [(OR=1.5; 95%CI: 1.1-6.4), p=.03]. However, only 51% of network members disclosed an HIV status and women disclosed to 50% of their network members. In a context of high background HIV prevalence and low levels of HIV status disclosure, serodiscordant mixing patterns likely facilitate transmission.  相似文献

OBJECTIVES: We evaluated the relationship between U.S. citizenship status and the receipt of Pap smears and mammograms among immigrant women in California. DESIGN: Cross-sectional study using data from the 2001 California Health Interview Survey. PATIENTS/PARTICIPANTS: Noninstitutionalized, civilian women, aged 18 years and older living in California. MEASUREMENTS AND MAIN RESULTS: We analyzed data from the 2001 California Health Interview Survey and used logistic regression models to adjust for sociodemographic factors and for access and utilization of health services. After adjusting we found that U.S. citizen immigrants were significantly more likely to report receiving a Pap smear ever (adjusted prevalence ratio [aPR], 1.05; 95% confidence interval [CI], 1.01 to 1.08), a recent Pap smear (aPR, 1.07; 95% CI, 1.03 to 1.11), a mammogram ever (aPR, 1.17; 95% CI, 1.12 to 1.21), and a recent mammogram (aPR, 1.38; 95% CI, 1.26 to 1.49) as compared to immigrants who are not U.S. citizens. Also associated with receiving cancer screening were income, having a usual source of care, and having health insurance. Hispanic women were more likely to receive Pap smears as compared to whites and Asians. CONCLUSIONS: Not being a U.S. citizen is a barrier to receiving cervical and breast cancer screening. Additional research is needed to explore causal factors for differences in cancer screening rates between citizens and noncitizens.  相似文献

Our objective was to examine associations between self-reported sexually transmitted infections (STIs) and sociodemographic, lifestyle, health status, health service use and quality of life factors among young Australian women; and their use of family planning and sexual health clinics and associations with health, demographic and psychosocial factors. The study sample comprised 14,762 women aged 18-23 years who participated in the mailed baseline survey for the Australian Longitudinal Study on Women's Health, conducted in 1996. The main outcome measures are self report of ever being diagnosed by a doctor with an STI, including chlamydia, genital herpes, genital warts or other STIs, and use of family planning and sexual health clinics. The self-reported incidence of STI was 1.7% for chlamydia, 1.1% genital herpes, 3.1% genital warts, and 2.1% other STIs. There was a large number of demographic, health behaviour, psychosocial and health service use factors significantly and independently associated with reports of having had each STI. Factors independently associated with use of family planning clinic included unemployment, current smoking, having had a Pap smear less than 2 years ago, not having ancillary health insurance, having consulted a hospital doctor and having higher stress and life events score. Factors independently associated with use of a sexual health clinic included younger age, lower occupation status, being a current or ex-smoker, being a binge drinker, having had a Pap smear, having consulted a hospital doctor, having poorer mental health and having higher life events score. This study reports interesting correlates of having an STI among young Australian women aged 18-23. The longitudinal nature of this study provides the opportunity to explore the long-term health and gynaecological outcomes of having STIs during young adulthood.  相似文献

OBJECTIVES: Although human immunodeficiency virus (HIV)-infected patients are now living longer, there are no published data on colorectal cancer (CRC) screening in this population. We hypothesized that HIV-infected patients were less likely to be screened for CRC compared to patients without HIV. METHODS: Consecutive HIV-infected patients > or =50 yr old seen in our outpatient clinic from 1/1/01 to 6/30/02 were identified. For each HIV-infected patient, we selected one age- and gender-matched control subject without HIV infection who was seen during the same time period. The electronic medical records were reviewed to determine the proportion of patients that had a fecal occult blood test (FOBT), flexible sigmoidoscopy, air-contrast barium enema (ACBE), or colonoscopy. RESULTS: During the 18-month study period, 538 HIV-infected outpatients were seen and 302 (56.1%) were > or =50 yr old. Despite significantly more visits with their primary care provider, HIV-infected patients were less likely to have ever had at least one CRC screening test (55.6%vs 77.8%, p < 0.001). The proportion of HIV-infected patients who ever had a FOBT (43.0%vs 66.6%, p < 0.001), flexible sigmoidoscopy (5.3%vs 17.5%, p < 0.001), ACBE (2.6%vs 7.9%, p= 0.004), or colonoscopy (17.2%vs 27.5%, p= 0.002) was significantly lower than in control subjects. In addition, HIV-infected patients were significantly less likely to be up-to-date with at least one CRC screening test according to current guidelines (49.3%vs 65.6%, p < 0.001). CONCLUSIONS: A substantial number of HIV-infected patients are > or =50 yr of age and CRC screening is underutilized in this population. Public health strategies to improve CRC screening in HIV-infected patients are needed.  相似文献

BACKGROUND: Breast problems, including mastitis, can interfere with the duration and exclusivity of breast-feeding. However, there are no large prospective studies documenting the prevalence, duration, and timing of such problems in breast-feeding women, particularly those who are infected with human immunodeficiency virus (HIV). METHODS: Women enrolled prenatally underwent a breast-feeding counseling intervention until 6 months after delivery. Breast health problems were documented per breast for 180 days after delivery, with 14-day recall histories. RESULTS: Breast health problems were rare, and there were no significant differences between HIV-infected and HIV-uninfected women for any of the following conditions: engorgement, 39 HIV-infected women (3.5%) versus 33 HIV-uninfected women (2.7%; P=.30); breast thrush, 17 (1.5%) versus 12 (1.0%; P=.25); bleeding nipple, 6 (0.5%) versus 4 (0.3%; P=.45); and mastitis/abscess, 11 (1.0%) versus 6 (0.5%; P=.17). Most problems occurred during the first month after birth, with few additional mothers experiencing problems after this point: at 1 and 6 months, 13% and 17% of all mothers, respectively, had experienced a minor or major breast health problem, including sore nipples. Women who had not exclusively breast-fed their infants were more likely to experience any of the breast health problems than were women who had exclusively breast-fed their infants (time-dependent variable; adjusted odds ratio, 1.46; 95% confidence interval, 1.13-1.87; P=.003). HIV-infected women who experienced any serious breast health problem (i.e., bleeding nipple, pus oozing from a nipple or breast, or mastitis/abscess) were 3.55 times (95% confidence interval, 0.86-14.78 times; P=.08) more likely to transmit HIV postnatally to their infant. CONCLUSIONS: With encouragement to exclusively breast-feed, women experienced few breast health problems. When those problems did occur, HIV-infected women with bleeding nipple, pus oozing from a nipple or breast, or mastitis/abscess were more likely to transmit HIV to their infants.  相似文献

This project evaluated perceived risks and benefits and determined predictors of acceptance of voluntary HIV counselling and testing (VCT) among pregnant women in Zimbabwe. One hundred and seventy pregnant women attending an urban antenatal clinic were surveyed. Implications of a negative or positive HIV test result and of telling a partner or community members that one is HIV positive were queried. Forty women (23.5%) consented to VCT, and 16 (40%) were HIV positive. Women who saw VCT as lower risk (odds ratio [OR] = 2.3, 95% confidence interval [CI] [1.1-5.0]) and women who had had a stillbirth or child die (OR = 0.4, 95% CI [0.16-0.97]) were more likely to consent. Prenatal HIV VCT offers the best opportunity for prevention of mother-to-child transmission of HIV; however, less than 25% of women consented. If such interventions are to be successful, attention must be directed towards developing culturally appropriate strategies to address women's concerns and improve future acceptance of VCT in Zimbabwe.  相似文献
