Prevalence and Risk Factors of PrEP Use Stigma Among Adolescent Girls and Young Women in Johannesburg, South Africa and Mwanza, Tanzania Participating in the EMPOWER Trial.

Adolescent girls and young women (AGYW) in sub-Saharan Africa may benefit from pre-exposure prophylaxis (PrEP), yet stigma may limit PrEP acceptance and continuation. We examined factors associated with PrEP use stigma among 307 participants of the EMPOWER trial (2016-2018), an unblinded randomized controlled trial among HIV-negative, AGYW, aged 16-24, in South Africa and Tanzania. The 6-item, brief-PrEP use stigma scale (B-PSS) had high internal reliability. At the end of the trial, 34.2% of study participants reported any PrEP use stigma. Three latent classes were observed, reflecting low (46.9%), medium (31.9%), and high (21.2%) reported PrEP use stigma. Disclosure of PrEP use to sexual partner and belief that PrEP prevents HIV were associated with less reported PrEP use stigma. Conversely, participants who reported fear and shame about people living with HIV were more likely to report PrEP use stigma. Our validated tool and findings will enable practitioners to identify AGYW at high risk of PrEP use stigma who may benefit from additional support.Pan African clinical trials registry PACTR202006754762723, 5 April 2020, retrospectively registered.

Cost and cost-effectiveness of tuberculosis treatment shortening: a model-based analysis.

BACKGROUND: Despite improvements in treatment success rates for tuberculosis (TB), current six-month regimen duration remains a challenge for many National TB Programmes, health systems, and patients. There is increasing investment in the development of shortened regimens with a number of candidates in phase 3 trials. METHODS: We developed an individual-based decision analytic model to assess the cost-effectiveness of a hypothetical four-month regimen for first-line treatment of TB, assuming non-inferiority to current regimens of six-month duration. The model was populated using extensive, empirically-collected data to estimate the economic impact on both health systems and patients of regimen shortening for first-line TB treatment in South Africa, Brazil, Bangladesh, and Tanzania. We explicitly considered 'real world' constraints such as sub-optimal guideline adherence. RESULTS: From a societal perspective, a shortened regimen, priced at USD1 per day, could be a cost-saving option in South Africa, Brazil, and Tanzania, but would not be cost-effective in Bangladesh when compared to one gross domestic product (GDP) per capita. Incorporating 'real world' constraints reduces cost-effectiveness. Patient-incurred costs could be reduced in all settings. From a health service perspective, increased drug costs need to be balanced against decreased delivery costs. The new regimen would remain a cost-effective option, when compared to each countries' GDP per capita, even if new drugs cost up to USD7.5 and USD53.8 per day in South Africa and Brazil; this threshold was above USD1 in Tanzania and under USD1 in Bangladesh. CONCLUSION: Reducing the duration of first-line TB treatment has the potential for substantial economic gains from a patient perspective. The potential economic gains for health services may also be important, but will be context-specific and dependent on the appropriate pricing of any new regimen.

The need for an integrated approach for chronic disease research and care in Africa.

With the changing distribution of infectious diseases, and an increase in the burden of non-communicable diseases, low- and middle-income countries, including those in Africa, will need to expand their health care capacities to effectively respond to these epidemiological transitions. The interrelated risk factors for chronic infectious and non-communicable diseases and the need for long-term disease management, argue for combined strategies to understand their underlying causes and to design strategies for effective prevention and long-term care. Through multidisciplinary research and implementation partnerships, we advocate an integrated approach for research and healthcare for chronic diseases in Africa.

H3Africa multi-centre study of the prevalence and environmental and genetic determinants of type 2 diabetes in sub-Saharan Africa: study protocol.

The burden and aetiology of type 2 diabetes (T2D) and its microvascular complications may be influenced by varying behavioural and lifestyle environments as well as by genetic susceptibility. These aspects of the epidemiology of T2D have not been reliably clarified in sub-Saharan Africa (SSA), highlighting the need for context-specific epidemiological studies with the statistical resolution to inform potential preventative and therapeutic strategies. Therefore, as part of the Human Heredity and Health in Africa (H3Africa) initiative, we designed a multi-site study comprising case collections and population-based surveys at 11 sites in eight countries across SSA. The goal is to recruit up to 6000 T2D participants and 6000 control participants. We will collect questionnaire data, biophysical measurements and biological samples for chronic disease traits, risk factors and genetic data on all study participants. Through integrating epidemiological and genomic techniques, the study provides a framework for assessing the burden, spectrum and environmental and genetic risk factors for T2D and its complications across SSA. With established mechanisms for fieldwork, data and sample collection and management, data-sharing and consent for re-approaching participants, the study will be a resource for future research studies, including longitudinal studies, prospective case ascertainment of incident disease and interventional studies.

How long-distance truck drivers and villagers in rural southeastern Tanzania think about heterosexual anal sex: a qualitative study.

OBJECTIVE: To explore ideas of truck drivers and villagers from rural Tanzania about heterosexual anal sex (HAS) and the associated health risks. METHODS: Qualitative study using 8 in-depth interviews (IDIs) and 2 focus group discussions (FGDs) with truck drivers and 16 IDIs and 4 FGDs with villagers from the Morogoro region. Study participants included 24 women and 46 men. Data analysis was performed thematically employing standard qualitative techniques. RESULTS: Reasons why men would practice HAS included sexual pleasure, the belief that anal sex is safer than vaginal sex, alternative sexual practice, exploration and proof of masculinity. Reasons why women would practice HAS included financial need, retaining a partner, alternative for sex during menses, pregnancy prevention and beauty enhancement because HAS is believed to 'fatten the female buttocks'. Most participants believed that condoms are not needed during HAS. This was linked to the ideas that infections only 'reside in wet places' (vagina) and that the anus is not 'conducive' for condom use; condoms reduce 'dryness' and 'friction' (pleasure) and may 'get stuck inside'. CONCLUSIONS: The study participants reported practices and ideas about HAS that put them at risk for HIV and sexually transmitted infections. Greater attention to education about HAS is urgently needed in Tanzania, where this sexual practice is still regarded as a taboo. This study offers useful information that could be included in sex education programmes.

Acyclovir and transmission of HIV-1 from persons infected with HIV-1 and HSV-2.

BACKGROUND: Most persons who are infected with human immunodeficiency virus type 1 (HIV-1) are also infected with herpes simplex virus type 2 (HSV-2), which is frequently reactivated and is associated with increased plasma and genital levels of HIV-1. Therapy to suppress HSV-2 reduces the frequency of reactivation of HSV-2 as well as HIV-1 levels, suggesting that suppression of HSV-2 may reduce the risk of transmission of HIV-1. METHODS: We conducted a randomized, placebo-controlled trial of suppressive therapy for HSV-2 (acyclovir at a dose of 400 mg orally twice daily) in couples in which only one of the partners was seropositive for HIV-1 (CD4 count, > or = 250 cells per cubic millimeter) and that partner was also infected with HSV-2 and was not taking antiretroviral therapy at the time of enrollment. The primary end point was transmission of HIV-1 to the partner who was not initially infected with HIV-1; linkage of transmissions was assessed by means of genetic sequencing of viruses. RESULTS: A total of 3408 couples were enrolled at 14 sites in Africa. Of the partners who were infected with HIV-1, 68% were women, and the baseline median CD4 count was 462 cells per cubic millimeter. Of 132 HIV-1 seroconversions that occurred after randomization (an incidence of 2.7 per 100 person-years), 84 were linked within couples by viral sequencing: 41 in the acyclovir group and 43 in the placebo group (hazard ratio with acyclovir, 0.92, 95% confidence interval [CI], 0.60 to 1.41; P=0.69). Suppression with acyclovir reduced the mean plasma concentration of HIV-1 by 0.25 log(10) copies per milliliter (95% CI, 0.22 to 0.29; P<0.001) and the occurrence of HSV-2-positive genital ulcers by 73% (risk ratio, 0.27; 95% CI, 0.20 to 0.36; P<0.001). A total of 92% of the partners infected with HIV-1 and 84% of the partners not infected with HIV-1 remained in the study for 24 months. The level of adherence to the dispensed study drug was 96%. No serious adverse events related to acyclovir were observed. CONCLUSIONS: Daily acyclovir therapy did not reduce the risk of transmission of HIV-1, despite a reduction in plasma HIV-1 RNA of 0.25 log(10) copies per milliliter and a 73% reduction in the occurrence of genital ulcers due to HSV-2.

Rapid HIV testing and counselling in labour in a northern Nigerian setting.

Between April and August 2004, all pregnant women in labour at JUTH, were offered rapid HIV testing and counselling with opportunity to decline testing. HIV positive women were offered the standard nevirapine mono-therapy prophylaxis regimen (HIVNET 012). Four hundred and thirty (99.8%) of the 431 pregnant women who were offered rapid HIV testing and counselling, agreed to test. A sero-conversion rate of 2.1% (5 of 235) was found among women who had previously tested negative for HIV during the index pregnancy. A seroprevalence rate of 9.6% (16 of 166) was found among women with unknown HIV status. One patient who had an indeterminate HIV status prior to labour tested positive in labour. Rapid HIV testing and counselling in labour is a useful practice in high prevalence settings since it detects a substantial number of HIV-infected women and HIV-exposed babies that would otherwise have missed interventions to prevent MTCT.

Socio-economic and demographic factors associated with prevalence of HIV infection among pregnant women in Dar es Salaam, Tanzania.

BACKGROUND: HIV/AIDS epidemic has become generalised in low resource settings in sub-Saharan Africa where 90% of all maternal-foetal transmission of HIV infection occurs. Global effort to scale-up pMTCT is underway, however, mechanisms to maximise screening of HIV- 1 positive women for Nevirapine treatment and other interventions, are not clear. OBJECTIVE: To identify socioeconomic and demographic characteristics associated with the prevalence of HIV- 1 infection among Tanzanian women. DESIGN: Cross-sectional study. SETTING: Four antenatal clinics in Dar es Salaam. RESULTS: HIV prevalence rate was 13.1 (95% confidence interval (CI): 12.7% - 13.5%) and it increased with increasing maternal age. Older age than 25, mid-arm circumference less than 25cm, geographic location, working in a public house, and partner's occupation were independently associated with higher prevalence of infection. Women in monogamous marriages were 77% less likely to be HIV infected compared to women with no regular partner. Similarly, women with more than five persons per household, and those who spent less on food had a significantly lower HIV prevalence. CONCLUSION: HIV infection is sufficiently widespread among women in Dar es Salaam suggesting that screening based on socioeconomic and demographic characteristics would miss a large proportion of the positives. There is need to increase facilities for counselling and testing using an opt-out approach for testing in all antenatal clinics in the city.

The epidemiology of HIV-1 infection in northern Tanzania: results from a community-based study.

We conducted a community-based study to determine the predictors of HIV-1 among women aged 20-44 years (N = 1,418) and their regular male partners (N = 566) from randomly selected households in Moshi, Tanzania. The weighted prevalence of HIV-1 was 10.3% in women and 7% in men. The highest risk of HIV-1 was in subjects whose partners were HIV-1 seropositive in both women (adjusted odds ratio (AOR) = 26.63; 95% confidence interval (CI): 10.74-66.02) and men (AOR = 22.25; 95%CI: 7.06-70.15). Herpes simplex virus type 2 (HSV-2) and Mycoplasma genitalium were also significantly associated with HIV-1. Women with male partners >or=12 years older than themselves had increased risk of HIV-1 (AOR = 1.99; 95%CI: 1.01-7.85). Other predictors of HIV-1 were history of infertility and the number of sex partners in the last three years in women and the age at time of circumcision and history of past sexually transmitted diseases (STDs) in male partners. These findings show that HIV-1/STDs were major public health problems among women and their long-term partners in this population. HIV-1 prevention efforts should include promotion of couple's HIV-1 counseling and testing services, control of HSV-2, promotion of safer sexual practices and strategies to reduce the age difference between women and their partners.

Risk factors for bacterial vaginosis among bar and hotel workers in Northern Tanzania.

OBJECTIVE: To determine risk factors for bacterial vaginosis (BV) among women working in the bars and hotels in Moshi, Northern Tanzania. RESULTS: Severe disturbances of vaginal flora or BV were detected in 70/268 (26.1%) women (95% confidence interval (CI): 20.8%-31.4%). In multivariate analyses, religion was the only socio-demographic characteristic that remained significantly associated with BV. Other independent predictors of BV were Trichomonas vaginalis (adjusted odds ratio (OR)=2.7, 95% CI: 1.4-5.3), Chlamydia trachomatis (adjusted OR=3.5, 95% CI: 1.2-10.6), syphilis (adjusted OR=7.1, 95% CI: 41.1-4.7) and herpes simplex virus type 2 (HSV-2) infection (adjusted OR=1.8, 95% CI: 1.0-3.3). CONCLUSION: Bacterial vaginosis (BV) was the common cause of genital symptoms in the study population. Since sexually transmitted diseases (STDs) were strongly associated with BV, control of STDs and BV should be given the highest priority in this population.

HIV infection among pregnant women in Nigeria.

OBJECTIVES: To determine risk factors for HIV among pregnant women (N = 2657) receiving antenatal services in Jos, Plateau state, Nigeria. METHODS: Information about potential risk factors was obtained at interview. Biological samples were collected for detection of HIV and other sexually transmitted infections (STIs). RESULTS: The prevalence of HIV was 8.2%. Women aged 20-29 years had more than 4-fold increased risk of HIV. Women of Catholic (adjusted odds ratio (AOR) = 1.72, 95% CI = 1.01-2.95) and Pentecostal (AOR = 2.57, 95% CI = 1.46-4.52) denominations were more likely to be HIV-infected when compared to Moslem women. The risk of HIV was also increased among women with multiple marriages and in women married to a banker/accountant. Other predictors of HIV were having a husband with other partners, perceived risk of HIV, STIs, candidiasis and bacterial vaginosis. CONCLUSIONS: Development of effective interventions, including behavioral change, expansion of perinatal HIV prevention services and STI control, should be given the highest priority.

Social and behavioural determinants of consistent condom use among hotel and bar workers in Northern Tanzania.

Bar and hotel workers (n=519) in Moshi, Tanzania were interviewed to obtain information about potential predictors of condom use. Samples were collected for the diagnosis of sexually transmitted diseases (STDs), including HIV. Consistent condom use was defined as always using condoms with sexual partners in the past five years. Overall consistent condom use in this population was 14.1%. In multivariate analyses, consistent condom use was inversely associated with low condom self-efficacy (adjusted odds ratio [AOR], 0.20; 95% confidence interval (CI), 0.06-0.71), low condom knowledge (AOR, 0.11; CI, 0.01-0.80), and having more than three children (AOR, 0.23; 95% CI, 0.09-0.54). Other significant predictors included perceived condom acceptability and using condoms when last exchanged sex for money or gift. These results indicate that increased specific condom knowledge, improved self-efficacy, and reduced social stigma could be effective strategies in the promotion of condom use in this population.

Male condom use in Tanzania: results from a national survey.

OBJECTIVE: To determine factors associated with male condom use in Tanzania. METHODS: Data from the 1996 Tanzania Demographic and Health Survey (TDHS) was used. In this survey, a national representative sample of sexually active men (N=1898) and women (N=7027) were interviewed to obtain information about potential predictors of sexual practices and condom use. RESULTS: Two hundred and ninety (4.1%) women and 288 (15.2%) men had used condoms during their last sexual encounter. Men aged 20-24 years and women aged 15-19 years reported the highest rate of condom use. In both men and women, condom use increased with increasing level of education. Residents of large urban centers were more likely to have used condoms among both women [adjusted OR=1.8, 95% CI=1.2-2.8] and men (adjusted O=2.0, 95% CI=1.3-3.1). Condom use was significantly increased among women (adjusted OR=6.2, 95% CI=4.4-8.8) and men [adjusted OR-5.9, 95% CI=3.2-8.8) practising high-risk sexual behaviour. Similarly, condom use was significantly increased among men who were never married and in those who had ever tested for AIDS. CONCLUSIONS: Condom promotion activities have been less successful in Tanzania. Additional efforts to increase condom acceptability and use are urgently needed.

Sexual behaviour patterns and condom use in Tanzania: results from the 1996 Demographic and Health Survey.

We conducted this study to determine the factors associated with high-risk sexual behaviour and condom use among men and women who participated in the 1996 Tanzania Demographic and Health Survey (TDHS); and to assess changes in sexual behaviour between 1991/92 and 1996 TDHS. Respondents were regarded to have practised high-risk sexual behaviour if they were married or cohabiting and had other regular or non-regular sexual partners; or if they were unmarried and had non-regular partners or multiple regular partners. About 8% of women and 29% of men practised high-risk sexual behaviour. High-risk sexual behaviour was common among younger men and women, and decreased with increasing level of education in women. Respondents who were unmarried, Muslims and those who perceived themselves at increased risk of HIV/AIDS were more likely to practise high-risk sexual behaviour. About 4% of women and 15% of men reported to have used condoms during their last sexual encounter. Condom users were significantly more likely to practise high-risk sexual behaviour. Overall, no major changes in sexual behaviour and condom use were observed during the period between the two surveys. Predictors of high-risk sexual behaviour and condom use identified in this report provide valuable information that can be used to design targeted HIV/AIDS interventions in Tanzania.

The association between maternal HIV-1 infection and pregnancy outcomes in Dar es Salaam, Tanzania.

OBJECTIVE: To examine the association between maternal HIV infection and pregnancy outcomes controlling for potential confounding factors among a cohort of HIV-uninfected and HIV-infected pregnant women in Dar es Salaam, Tanzania. DESIGN: Prospective cohort study. METHODS: A cohort of 1,078 HIV-infected and 502 HIV-uninfected pregnant women between 12 and 27 weeks of gestation were enrolled and followed up until delivery. Multiple regression models were used to compare the risk of adverse pregnancy outcomes among HIV-uninfected women with those among HIV-infected women overall, and separately among asymptomatic or symptomatic HIV-infected women. RESULTS: No significant differences between HIV-uninfected women and HIV-infected women were observed in risks of fetal loss or low birthweight or in the weight, head circumference and gestational age of infants at birth. HIV-infected women were more likely to have severe immature infants (<34 weeks) than HIV-uninfected women (multivariate RR 1.54 [95% CI 0.90-2.48]; P= 0.05). There was a significantly higher risk of low birthweight (RR 2.29, 95% CI 1.34-3.92; P = 0.03) and prematurity (<37 weeks) (RR 1.93, 95% CI 1.35-2.77; P = 0.0003) among symptomatic HIV-infected women when compared with HIV-uninfected women. CONCLUSION: HIV-infected women, particularly those whoare symptomatic, are at a higher risk of adverse pregnancy outcomes.

Risk factors for syphilis among HIV-1 infected pregnant women in Dar es Salaam, Tanzania.

This study was conducted to determine the risk factors for recent (active) syphilis among HIV-1 seropositive pregnant women (N = 1058) in Dar es Salaam, Tanzania, Recruitment of study participants (N = 1058) was done between April 1995 and June 1997 at four main prenatal clinics in Dar es Salaam city. Study subjects were interviewed to obtain information about potential risk factors, and blood and genital specimens were collected for detection of syphilis and other genital infections. The prevalence of active syphilis was 5.9%. After adjusting for other risk factors, women without their own source of income had a 50% lower risk of syphilis (OR = 0.5, 95% CI: 0.3-0.9). The risk of active syphilis was significantly increased among women with genital ulceration on examination (OR = 8.4, 95% CI: 1.5-47.7), and in those with trichomoniasis (OR = 2.2, 95% CI: 1.2-3.8). HIV-related immunodeficiency was not associated with increased risk of syphilis. These results show that syphilis and other genital infections are a major problem among HIV infected women. Prevention of syphilis and other genital infections is urgently needed in this population.

Risk factors for HIV-1 seroprevalence among family planning clients in Dar es Salaam, Tanzania.

Between March and September of 1995, women receiving family planning (FP) services in three large clinics in Dar es Salaam, Tanzania were invited to participate in a cross-sectional study. Consenting women were interviewed to obtain information about HIV risk factors, and blood for HIV testing was collected. The prevalence of HIV was 16.9% (95% CI: 14.4%-19.3%). The risk of HIV increased significantly with age. Compared with married women, the risk of HIV was significantly higher among cohabiting women (age-adjusted OR = 2.3; 95% CI = 1.5-3.5) and among women who were single, divorced or widowed (age-adjusted OR = 2.3; 95% CI = 1.2-4.4). The risk of HIV was also significantly higher among hotel workers (age-adjusted OR = 4.3; 95% CI = 1.4-12.9). Women with laboratory evidence of sexually transmitted diseases were at increased risk of HIV. This study shows that HIV is a major public health problem among FP clients in Tanzania. Innovative HIV interventions are needed to reduce further spread of HIV infection.

Randomized trial of vitamin supplements in relation to vertical transmission of HIV-1 in Tanzania.

BACKGROUND: Observational studies suggest that poor nutritional status among HIV-infected pregnant women is associated with a higher risk of vertical transmission of HIV. METHODS: We randomized 1083 pregnant women infected with HIV-1 in a double-blind, placebo-controlled trial to examine the effects of supplements of vitamin A and/or multivitamins (excluding vitamin A) using a 2-x-2 factorial design. We report the effects of the supplements on HIV infection defined using polymerase chain reaction (PCR), or death up to 6 weeks postpartum. RESULTS: Of babies in the multivitamin arm 38, (10.1%) were HIV-positive at birth compared with 24 (6.6%) in the no-multivitamin arm (relative risk [RR] = 1.54; 95% CI, 0.94-2.51; p = .08). Of babies born to mothers in the vitamin A arm, 38 (10.0%) were HIV-positive at birth compared with 24 (6.7%) in the no-vitamin A arm (RR, 1.49; 95% CI, 0.91-2.43; p = 0.11). Neither multivitamins nor vitamin A had an effect on HIV status at 6 weeks among those who were HIV-negative at birth (RR = 1.04; 95% CI, 0.65-1.66; p = 0.88) and (RR = 1.30; 95% CI, 0.80-2.09; p = .29, respectively). Similarly, neither supplement was associated with being either HIV-infected or dead at birth (RR, 0.98; 95% CI, 0.76-1.27; p = .89 and RR, 1.01; 95% CI, 0.78-1.31; p = .95, respectively. A beneficial effect of multivitamins on birth weight was limited to babies who were HIV-negative at birth; babies in the multivitamin arm weighed +94 g more compared with those in the no-multivitamin arm (p = .02). Among babies who were HIV-positive at birth, the corresponding difference was -31 g (p = .82). CONCLUSIONS: Vitamin A and multivitamins did not affect the risk of vertical transmission of HIV in utero nor during the intrapartum and early breastfeeding periods. Multivitamins resulted in a significant improvement in birth weight of babies who were HIV-negative at birth but had no effect among those who were HIV-positive. The effect of vitamin supplements on HIV transmission through breastfeeding and on clinical progression of HIV disease is yet to be ascertained.

Predictors of CD4+ lymphocyte count among HIV-seropositive and HIV-seronegative pregnant women in Dar es Salaam, Tanzania.

OBJECTIVE: To determine the predictors of CD4+ lymphocyte count among pregnant women in Dar es Salaam, Tanzania. METHODS: Between 04/1995 and 03/1997, HIV-seropositive (n=1,027) and HIV-seronegative (n=280) pregnant women were interviewed to obtain socio-demographic characteristics. Later, blood samples was collected for determination of T-lymphocyte subsets and other haematological indices. RESULTS: CD4+ lymphocyte count was significantly higher among HIV-seronegative women (mean=770 cells/mm3, standard deviation (SD)=232 cells/mm3) than HIV-seropositive women (mean=422 cells/mm3, SD=205 cells/mm3). Most HIV-seropositive women were asymptomatic, in WHO clinical stage 1 (84.3%). Among HIV-seropositive women, total white blood count (WBC) and erythrocyte sedimentation rate (ESR) remained significantly correlated with CD4+ after adjusting for other predictors in multivariate analyses. For women of average age 25 years, the CD4+ lymphocyte count increased by about 16 cells/mm3 for each increment of 1000 WBC cells/mm3, while each 10 mm/hr increase in ESR was associated with a reduction of CD4+ lymphocyte count of about 8 cells/mm3. CONCLUSION: These results show that simple and inexpensive haematological indices cannot be recommended for use as alternative measures of HIV-related immunosuppression in this population of mainly asymptomatic women.

Risk factors for cervical squamous intraepithelial lesions among HIV-1 seropositive women in Dar es Salaam, Tanzania.

OBJECTIVES: To determine the prevalence and risk factors for cervical squamous intraepithelial lesions (SIL) among HIV-infected women in Dar es Salaam, Tanzania. METHODS: Between July 1996 and December 1997 we interviewed 691 HIV-infected women to obtain information about risk factors for SIL. Cervical smears and samples for lymphocyte subsets and sexually transmitted diseases (STD) diagnosis were collected. RESULTS: The prevalence of SIL was 2.9% (20/686) (95% CI = 1.7-4.2%). Eleven women had low-grade SIL while nine women had high-grade SIL. The number of lifetime sexual partners and live births was associated with a marginally non-significant increased risk of SIL. The risk of SIL was significantly increased among women with CD4+ cell count < 200/mm3 (multivariate odds ratio (OR) = 6.15, 95% CI = 1.19-41.37) and decreased by 68% for each 5-cm increase in mid-upper arm circumference (multivariate OR = 0.32, 95% CI = 0.10-0.93). CONCLUSIONS: HIV-related immunosuppression and wasting and long-term sexual behavior were the major determinants of SIL in this population. Federation of Gynecology and Obstetrics.
