OBJECTIVES To study the prevalence, type, social correlates and attitudes towards female genital cutting (FGC) among urban women in Kilimanjaro, Tanzania; and to examine the association between FGC and gynaecological problems, reproductive tract infections (RTIs) and HIV.

HIV among pregnant women in Moshi Tanzania: the role of sexual behavior, male partner characteristics and sexually transmitted infections

BackgroundWomen continue to be disproportionately affected by HIV in Tanzania, and factors contributing to this situation need to be identified. The objective of this study was to determine social, behavioral and biological risk factors of HIV infection among pregnant women in Moshi urban, Tanzania. In 2002 – 2004, consenting women (N = 2654), attending primary health clinics for routine antenatal care were interviewed, examined and biological samples collected for diagnosis of HIV and other sexually transmitted/reproductive tract infections.ResultsThe prevalence of HIV was 6.9%. The risk for HIV was greater among women whose male partner; had other sexual partners (adjusted odds ratio [AOR], 15.11; 95% confidence interval [CI], 8.39–27.20), traveled frequently (AOR, 1.79; 95% CI, 1.22–2.65) or consumed alcohol daily (AOR, 1.68; 95% CI, 1.06–2.67). Other independent predictors of HIV were age, number of sex partners, recent migration, and presence of bacterial vaginosis, genital ulcer, active syphilis and herpes simplex virus type 2.ConclusionDevelopment of programs that actively involve men in HIV prevention is important in reducing transmission of HIV in this population. Further, interventions that focus on STI control, the mobile population, sexual risk behavior and responsible alcohol use are required.

Predictors of Failure to Return for HIV Test Results Among Pregnant Women in Moshi, Tanzania

Summary: Identification of HIV-infected women is a prerequisite in HIV perinatal prevention programs. The aim of this study was to determine the predictors of failure to return for HIV posttest results among pregnant women (N = 2654) receiving antenatal care at primary health clinics in Moshi urban district, Tanzania. Consenting pregnant women, who were in the third trimester of pregnancy, received individual pretest counseling, followed by interview and screening for HIV. Posttest counseling and results were given after 1 week. A total of 182 (7%) failed to return for their HIV test results. Women were less likely to return for test results if their partners did not come for testing (adjusted odds ratio [AOR], 12.6; 95% CI, 3.1-51.4), if their partners consumed alcohol (AOR, 1.8; 95% CI, 1.3-2.7), and if they had never discussed reproductive health matters with their partners (AOR, 1.7; 95% CI, 1.1-2.7). Additionally, the site of recruitment, age, alcohol consumption, and advanced gestation age predicted failure to return for HIV test results. These results indicate that male partner factors were important in determining whether women returned for results. We therefore recommend promotion of antenatal couple counseling and strengthening of community awareness of the availability of perinatal interventions, with special efforts targeting men. Furthermore, the predictors for failure to collect test-results need to be addressed during pretest counseling.

HIV seroprevalence and its associations with the other reproductive tract infections in asymptomatic women in Harare, Zimbabwe

The objective was to determine the magnitude of HIV as well as the associations between HIV seropositivity with reproductive tract infections (RTIs) among healthy women in Harare, Zimbabwe. In a cross-sectional study, 393 informed consenting women aged 15-49 years, attending 2 primary healthcare clinics, were interviewed and screened for HIV and RTIs. HIV seroprevalence was 29.3%. Seropositivity was significantly associated with bacterial vaginosis, syphilis, gonorrhoea and/or Chlamydia trachomatis infection, warts and genital ulcers. Risk factors for HIV were absence of lactobacilli in vaginal fluid, vaginal pH >4.5, age >20 years, being unmarried, having had more than one lifetime sexual partner, having used a condom at least once in their lifetime, having experienced an infant mortality, and a partner who was non-monogamous or a frequent traveller. In view of the very high seroprevalence and concomitant RTIs in this population, we recommend promotion of women-controlled prevention methods along with proactive detection and treatment of RTIs.

Prevalence of sexually transmitted infections among pregnant women with known HIV status in northern Tanzania

ObjectivesTo determine the prevalence of sexually transmitted infections (STIs) and other reproductive tract infections (RTIs) among pregnant women in Moshi, Tanzania and to compare the occurrence of STIs/RTIs among human immunodeficiency virus (HIV)-infected and uninfected women.MethodsPregnant women in their 3rd trimester (N = 2654) were recruited from two primary health care clinics between June 2002 and March 2004. They were interviewed, examined and genital and blood samples were collected for diagnosis of STIs/RTIs and HIV.ResultsThe prevalence of HIV, active syphilis and herpes simplex virus – type 2 (HSV-2) were 6.9%, 0.9% and 33.6%, respectively, while 0.5% were positive for N gonorrhoeae, 5.0% for T vaginalis and 20.9% for bacterial vaginosis. Genital tract infections were more prevalent in HIV-seropositive than seronegative women, statistically significant for syphilis (3.3% vs 0.7%), HSV-2 (43.2% vs 32.0%), genital ulcers (4.4% vs 1.4%) and bacterial vaginosis (37.2% vs 19.6%). In comparison with published data, a declining trend for curable STIs/RTIs (syphilis, trichomoniasis and bacterial vaginosis) was noted.ConclusionRates of STIs and RTIs are still high among pregnant women in Moshi. Where resources allow, routine screening and treatment of STIs/RTIs in the antenatal care setting should be offered. Higher STIs/RTIs in HIV-seropositive women supports the expansion of HIV-counseling and testing services to all centers offering antenatal care. After identification, STIs/RTIs need to be aggressively addressed in HIV-seropositive women, both at antenatal and antiretroviral therapy care clinics.

Seroprevalence and correlates of herpes simplex virus type 2 among urban Tanzanian women.

Background Data on herpes simplex virus type 2 (HSV-2) among women in the general population of developing countries are limited. Goals The goal of the study was to determine the seroprevalence of HSV-2 and to identify clinical, demographic, and behavioral correlates among women attending primary health care clinics. Study Design This was a cross-sectional survey of 382 randomly chosen women aged 15 to 49 years. Results The seroprevalence of HSV-2 was 39%. Only 2% had a history of genital herpes. HSV-2 was associated with antibody to HIV-1 (OR = 2.3 [CI, 1.1–4.7]), syphilis (OR = 4.7 [CI, 1.4–4.7]), and genital ulcers (OR = 9.7 [CI 2.5–36.9]). Age, sexual debut, number of sex partners, and history of spontaneous abortion were found to be significantly associated with HSV-2. Eighty-two percent of the women with genital ulcers were HSV-2-seropositive, while syphilis accounted for 6% of cases. HSV-2 may thus be the most common cause of genital ulcers in this population. Conclusion In view of the high HSV-2 seroprevalence and its association with HIV-1 and genital ulcers, integration of HSV-2 therapeutic management in STD syndromic algorithms is recommended. Counseling on symptom recognition, asymptomatic shedding, and preventive measures is needed.

Reproductive tract infections and the risk of HIV among women in Moshi, Tanzania

Objectives.  The objectives of the study were to determine the prevalence of HIV and reproductive tract infections (RTIs); to compare the occurrence of RTIs among HIV‐infected and non‐infected women; and to assess the association of HIV with RTIs and behavioral factors among women aged 15–49 years.

Association of herpes simplex virus type 2 with the human immunodeficiency virus among urban women in Zimbabwe.

A cross-sectional study at two urban primary health care clinics in Zimbabwe was conducted among 393 consecutive women. The purpose was to determine the seroprevalence of herpes simplex virus type 2 (HSV-2), to identify coinfections and to determine the association between HSV-2, HIV and other sexually transmitted infections (STIs). Sera were tested for HSV-2, HIV and syphilis. Genital specimens were tested for the other STIs. The seroprevalence of ulcerative STIs tested was 42.2% for HSV-2 and 3.9% for syphilis. HSV-2 seropositive women had twice the risk of being HIV infected compared to HSV-2 seronegative women, adjusted OR=2.05 (95% CI=1.29-3.23). HSV-2 seropositivity was also associated with older age, a lower level of education, increase in the number of lifetime sexual partners and history of genital ulcers in the past six or more months. Our data suggest that in this population HSV-2 may contribute more to HIV infection than syphilis because of its high frequency. There is an urgent need for development of an effective HSV-2 vaccine.

Cervical dyskaryosis among women with and without HIV: prevalence and risk factors.

Women in developing countries often present for medical care with advanced cervical cancer, although this condition is preventable through regular screening and early treatment. This study sought to identify the prevalence and risk factors for cervical dyskaryosis among women in Zimbabwe with and without HIV. In a cross-sectional study, 200 consenting women were screened for cervical dyskaryosis and sexually transmitted infections (STI). The relationship between various risk factors for cervical dyskaryosis was examined. The overall prevalence of cervical dyskaryosis was high (19%), and significantly higher among HIV-infected women at 30% compared with 13% among seronegative women, with a peak at a younger age among seropositive women. Use of intravaginal herbs, practising intravaginal cleansing, being single, a history of three or more lifetime sexual partners and a history of previous STI were associated with cervical dysplasia. The high frequency of cervical abnormality lends weight to the demand for implementation of regular screening programmes and health education.

Decline in HIV prevalence among women of childbearing age in Moshi urban, Tanzania.

The objective of this study was to describe trends over time in HIV prevalence, sexually transmitted infections (STIs) and sexual behaviour among women in Moshi urban, Tanzania. Two cross-sectional studies were conducted in 1999 and in 2002–04 among women attending three primary health-care clinics. They were interviewed and screened for HIV and STIs. There was a significant decrease in HIV prevalence (11.5–6.9%). The decline was greatest among women aged 15–24 years. Syphilis, trichomoniasis, bacterial vaginosis, genital ulcers and reported STI symptoms also decreased significantly over the three-year inter-survey period. The proportion of women reporting casual sex decreased and knowledge of STI symptoms and health-care seeking behaviour improved. Herpes simplex virus type 2, genital warts, age at sexual debut, age at first pregnancy and condom use remained unchanged. In conclusion, decline in curable STIs and casual sex partners may partly explain the observed decline in HIV seroprevalence. Both STIs and sexual behaviour should be monitored in HIV sentinel surveillance. There remains a gap between knowledge of preventive behaviour and actual preventive practices.
