"A Baby Was an Added Burden": Predictors and Consequences of Unintended Pregnancies for Female Sex Workers in Mombasa, Kenya: A Mixed-Methods Study

Contraceptive use, prevalence and incidence of pregnancy and associated factors among women participating in a vaccine preparedness cohort study in Masaka, Uganda, a retrospective secondary analysis

BACKGROUND

HIV prevention trials usually require that women of childbearing potential use an effective method of contraception. This is because the effect of most investigational products on unborn babies is unknown. We assessed contraceptive use, prevalence and incidence of pregnancy and associated factors among women in a HIV vaccine preparedness study in Masaka, Uganda.

METHODS

HIV sero-negative women (18-45 years) at high risk of HIV infection identified through HIV counselling and testing (HCT) were recruited between July 2018 and October 2022. Study procedures included collection of baseline socio-demographics and contraceptive use data, quarterly HCT, counselling on and provision of contraceptive methods onsite/through referral, and 6-monthly urine pregnancy tests. Multivariable Logistic and Poisson regression analyses were conducted to determine factors associated with contraceptive use, prevalence, and incidence of pregnancy.

RESULTS

652 (73%) of 891 women reported contraceptive use at baseline. Contraceptive use was higher in women who were in a relationship/married/cohabiting [adjusted odds ratio (aOR) = 1.60; 95% confidence interval (CI) 1.07-2.40] or divorced/separated/widowed [aOR = 1.86; 95% CI 1.24-2.79] versus those that were single, and among women reporting transactional sex [aOR = 2.10; 95% CI 1.16-3.80] versus those who did not. Baseline pregnancy prevalence was 4% (95% CI 3-6%) and lower in women who reported using long-acting contraceptive methods (aOR = 0.17; 95% CI 0.07-0.39) versus women who did not use these methods. A total of 65 pregnancies over 301.3 person-years of observation (PYO), an incidence rate of 21.6/100 (95% CI 16.9-27.5) PYO, higher among younger women (≤ 24 versus 25 + years, adjusted incidence rate ratio = 1.97; 95% CI 1.15-3.40).

CONCLUSION

We observed a high pregnancy incidence in this cohort. Innovative strategies that promote sustained and consistent use of highly effective contraceptive methods especially for young women will be critical to the success of HIV prevention trials in this and similar populations.

Gynecological health care services utilization and violence among female sex workers in Togo in 2021

BACKGROUND

Female Sex Workers (FSW) in Sub Saharan Africa face multiple challenges increasing their vulnerability to poor health, particularly poor sexual and reproductive (SRH) health outcomes and violence. The aim of this study was to assess the use of gynecology health care services and factors associated with its use as well as experiences of violence among FSW in Togo.

METHOD

A cross-sectional study was carried out in 2021 among FSW in two cities of Togo. A snowball sampling method was used and initial seeds were identified in each site in collaboration with FSW non-governmental organizations. A logistic regression was performed to identify factors associated with the use of a SRH service and violence.

RESULTS

A total of 447 FSW with a median age of 30 [IQR: (24-38)] participated in this study and 43.4% of them had reached at least secondary school. Among them, 29.1% reported having been to a gynecological consultation over the previous year. Factors associated with a gynecological consultation included: living in the Lomé capital city (aOR = 0.35, 95%CI 0.22-0.54), and an experience of condom breakage or slippage (aOR = 2.00; 95%CI 1.19-2.64). The majority reported at least one lifetime pregnancy (87.9%), 39.8% reported ever having an unintended pregnancy and 67.6% of them ever had an abortion. Finally, 61.1% indicated being victims of physical, sexual, or emotional violence in the previous six months. Sex workers living in Lomé (aOR = 1.78; 95%CI 1.16-2.73); a history of abortion (aOR = 1.53; 95%CI 1.03-2.31) and having more than 15 clients per week (aOR = 4.87; 95% CI 1.99-11.94), were more likely to experience violence.

CONCLUSION

There is an under-utilization of health care services among FSW in Togo in addition to overall poor sexual and reproductive health outcomes with a high prevalence of gender-based violence. Those results highlight the importance of continued advocacy for the integration of SRH care with HIV prevention services geared toward FSW as well as a holistic approach to SRH care with innovative ways to prevent violence.

The preventable burden of mortality from unsafe abortion among female sex workers: a Community Knowledge Approach survey among peer networks in eight countries

Previous studies have found high levels of unintended pregnancy among female sex workers (FSW), but less attention has been paid to their abortion practices and outcomes. This study is the first to investigate abortion-related mortality among FSW across eight countries: Angola, Brazil, Democratic Republic of Congo (DRC), India, Indonesia, Kenya, Nigeria, and South Africa. The Community Knowledge Approach (CKA) was used to survey a convenience sample of FSW (n = 1280). Participants reported on the deaths of peer FSW in their social networks during group meetings convened by non-governmental organisations (n = 165 groups, conducted across 24 cities in 2019). Details on any peer FSW deaths in the preceding five years were recorded. The circumstances of abortion-related deaths are reported here. Of the 1320 maternal deaths reported, 750 (56.8%) were due to unsafe abortion. The number of abortion-related deaths reported was highest in DRC (304 deaths reported by 270 participants), Kenya (188 deaths reported by 175 participants), and Nigeria (216 deaths reported by 312 participants). Among the abortion-related deaths, mean gestational age was 4.6 months and 75% occurred outside hospital. Unsafe abortion methods varied by country, but consumption of traditional or unknown medicines was most common (37.9% and 29.9%, respectively). The 750 abortion-related deaths led to 1207 children being left motherless. The CKA successfully recorded a stigmatised practice among a marginalised population, identifying very high levels of abortion-related mortality. Urgent action is now needed to deliver comprehensive sexual and reproductive healthcare to this vulnerable population, including contraption, safe abortion, and post-abortion care.

Unintended pregnancy and contraceptive use among women in low- and middle-income countries: systematic review and meta-analysis

INTRODUCTION

Unintended pregnancy is a leading cause of maternal mortality associated with abortion, inadequate contraceptive use, contraceptive failure, and contraceptive discontinuation in low- and middle-income countries. Most unintended pregnancies occur in regions with limited availability of maternal health services, resulting in a significant number of maternal deaths. Therefore, this review aimed to assess the overall prevalence of unintended pregnancy among women using contraceptives in low- and middle-income countries.

METHOD

PubMed, Science Direct, Google Scholar, Scopus, and the Ethiopian University Online Library were searched. Data were extracted using Microsoft Excel and analyzed using STATA statistical software (version 14). Publication bias was checked using forest plot, Begg rank test, and Egger regression test. To check for heterogeneity, I2 was calculated and an overall estimation analysis was performed. Subgroup analysis was conducted by study setting, study design, and publication. The Joanna Briggs Institute quality assessment tool was used to assess the quality of each study. We performed a one-time sensitivity analysis.

RESULTS

Of the 1304 articles retrieved, 23 studies (involving 40,338 subjects) met the eligibility criteria and were included in this study. The pooled prevalence of unintended pregnancy among women using contraceptives in low- and middle-income countries was 44.68% (95% CI: 35.16-54.20; I2 = 99.7%, P < 0.001). Based on subgroup analysis, the pooled prevalence of unintended events was 43.58% (CI: 32.99, 54.173) and 49.93% (CI: 28.298, 71.555) for cross-sectional and cohort studies, respectively. Based on the study design, it was 34.47% (CI: 27.012, 41.933) for community studies and 55.85% (CI: 33.364, 78.339) for institutional studies.

CONCLUSION

The overall prevalence of unintended pregnancy was high among women using contraceptives in low- and middle-income countries. Therefore, it is better to pay attention to prevention strategies for unintended pregnancy, such as information and education accessibility and contraceptive utilization.

Women's autonomy in refusing risky sex in sub-Saharan Africa: Evidence from 30 countries

Understanding the factors associated with women's autonomy to refuse risky sex is imperative to inform the development of policies and interventions to reduce the risk of unintended pregnancies, sexually transmitted infections, unsafe abortion, and maternal mortality. This study sought to examine the prevalence and factors associated with women's autonomy to refuse risky sex in sub-Saharan Africa (SSA). Data for the study were extracted from the most recent Demographic and Health Surveys (DHS) of thirty countries in SSA conducted from 2010 to 2020. We included a weighted sample of 260,025 women who were married or cohabiting in the final analysis. Percentages were used to present the results of the prevalence of women's ability to refuse risky sex. We used a multilevel logistic regression analysis to examine the factors associated with women's ability to refuse risky sex. Stata software version 16.0 was used for the analysis. We found that 61.69% (95% confidence interval [CI]: 56.22-67.15) of the women were autonomous to refuse sex if their partners have other women, and this was highest in Namibia (91.44% [95% CI: 90.77-92.18]) and lowest in Mali (22.25% [95% CI: 21.24-23.26]). The odds of autonomy in refusing risky sex was higher among women with higher education (adjusted odds ratio [aOR] = 1.88; 95% CI = 1.78-1.46) compared to those with no formal education. Employment status was also a significant predictor, with working women having higher odds of sex refusal compared to non-working women (aOR = 1.16; 95% CI = 1.13-1.18). Advocacy to improve women's autonomy to refuse risky sex must leverage the mass media as it emerged as a significant factor. Policies and intervention to enhance women's autonomy must also target high-risk sub-populations which constitutes adolescent girls, those with no formal education, and those without employment.

Global epidemiology of abortion among female sex workers: a systematic review, meta-analysis, and meta-regression

PURPOSE

Despite the evidence of a high rate of unintended pregnancy, there remains limited information about the prevalence and experiences of abortion among female sex workers (FSWs). In response, we aimed to summarize the available evidence on abortion among FSWs.

METHODS

We searched Medline, Embase, PsycINFO, CINAHL, Scopus, and Web of Science from inception to January 29, 2023 . We pooled data from the included studies using random-effects meta-analyses. We also grouped countries for the legality of elective abortion stratified by the United Nations database on abortion laws and policies.

RESULTS

We identified 60 eligible studies from 2031 potentially eligible records. The pooled lifetime prevalence of at least one and multiple induced abortions was 37.7% (95% confidence interval, 31.8-43.7) and 21.7% (14.9-29.2), respectively. Among FSWs recruited in countries where elective abortion is illegal, at least one induced abortion prevalence was 35.1% (28.1-42.4), and multiple induced abortion prevalence was 23.1% (12.4-35.9). In countries where elective abortion is legal, at least one induced abortion prevalence was 44.6% (34.8-54.6), and multiple induced abortion prevalence was 19.9% (11.9-29.3). Among FSWs experiencing abortion, self-managed abortion prevalence was estimated at 32.8% (23.6-42.7) overall, 42.8% (37.2-48.5) for countries where elective abortion is illegal, and 15.6% (3.9-32.7) for countries that legally allow elective abortion.

CONCLUSIONS

Induced abortion is prevalent among FSWs, highlighting the need for interventions to increase access to effective contraception and safe abortion care. While induced abortion prevalence did not significantly differ across the legal grounds for abortion, self-managed abortion prevalence was higher in countries where elective abortion was illegal, highlighting the urgent need for accessible abortion services for FSWs in criminalized settings. Moving forward necessitates implementing and evaluating culturally acceptable models of safe abortion and post-abortion care for FSWs to increase access to the full spectrum of sexual and reproductive health services.

Longitudinal study of pregnancy intention and its association with pregnancy occurrence among female sex workers in Benin and Mali

BACKGROUND

The intention of becoming pregnant has an evident impact on the prenatal and postnatal period. For female sex workers (FSWs) in West Africa, among whom pregnancies are frequent as are HIV and sexually transmitted infections, a better understanding of their pregnancy intention and its influence on pregnancy occurrence could help prevent unwanted pregnancies and adverse effects on wanted pregnancies.

METHODS

We recruited 330 FSWs in Benin and 322 in Mali and followed them for 12 months. We evaluated their pregnancy intention at recruitment and 6-month follow-up, using a multidimensional prospective measure that we developed. We assessed pregnancy occurrence with a pregnancy test and a retrospective questionnaire at 6 and 12 months. A Cox proportional hazard model was used to estimate the association between intention and pregnancy. We carried out an analysis to take losses to follow-up into account using the inverse of probability of censoring weights and a cluster analysis to corroborate that the multidimensional measure of pregnancy intention fitted the data.

RESULTS

407 FSWs were included in the first 6-month analysis and 284 at 12 months. Mean age was 30.9 years. The pregnancy intention distribution was similar between the two periods: 15.2% in the first period and 16.3% in the second had a positive intention. One out of four were ambivalent and almost 60% (57.7% and 56.3%) had a negative intention. For 38.2% of the FSWs, the intention changed between the two periods. The global incidence rate (to first event) was 19.1 pregnancies per 100 person-years. There was a borderline significant trend (p = 0.0529) of decreased pregnancy incidence with decreasing intention. Compared to positive intention, the adjusted hazard ratio (aHR) for ambivalent and negative intentions were 0.71 [95% confidence interval (95% CI) 0.32-1.60] and 0.46 (95% CI 0.21-1.01), respectively.

CONCLUSION

The level of pregnancy intention influences its occurrence among FSWs and nearly one out of six wants a baby despite working in the sex trade. Programmatically, early identification of these women could facilitate provision of quality antenatal and postnatal care. Given other health risks associated with sex work this care may decrease potential risks of adverse maternal, fetal and neonatal outcomes.

Barriers and facilitators for access and utilization of reproductive and sexual health services among Female Sex Workers in urban and rural Maharashtra, India

Background

The public health interventions among Female Sex Workers (FSWs) have mainly addressed HIV/ STI prevention. The focus of the HIV prevention program on FSWs' Reproductive and Sexual Health (RSH) has been limited, thus, rendering them at a higher risk of unintended pregnancies, delayed pregnancy detection, and utilizing unsafe abortion methods.

Methods

A multistakeholder analysis was performed to study access and use of RSH services among FSWs in urban and rural India. Between January 2016 and June 2019, a qualitative grounded theory approach was used to explore the FSWs' perspectives and experiences about services pertaining to HIV prevention, Antenatal Care (ANC), child delivery, abortion, and pregnancy prevention. Using purposive and convenience sampling, 29 In-Depth Interviews (IDIs), 2 Focus Group Discussions (FGDs) and 22 Key Informant Interviews (KIIs) were conducted with consenting FSWs and indirect stakeholders, respectively. Verbatim translated data was entered in NVivo12 Software and analyzed inductively.

Results

The following themes emerged: (1) Condomless sex, unintended pregnancy, vertical transmission, (2) Signs/ indication used for pregnancy detection causing delay (3) Pregnancy prevention methods used, (4) Pregnancy prevention or AIDS prevention, (5) Legal formalities as a barrier to access RSH, (6) Differential facility preference.

Conclusion

Pregnancy prevention is a greater motivation for condom use than HIV prevention among FSWs. Therefore, there is an emerging need to reallocate public health resources and redesign policies to meet the RSH needs of FSWs, especially for the prevention of unintended pregnancies. FSW-focused Information Education Communication (IEC) strategies for RSH service utilization are essential to reduce the burden of unintended pregnancies. The National HIV Targeted Intervention (TI) program needs to include pregnancy testing services and information to non-barrier contraceptive methods. An ambient policy environment calls for examining the need for male involvement in pregnancy, family planning and abortion decisions.

Assessment of the lifetime prevalence and incidence of induced abortion and correlates among female sex workers in Mombasa, Kenya: a secondary cohort analysis

INTRODUCTION

Prevalence of lifetime-induced abortion in female sex workers (FSWs) in Kenya was previously estimated between 43% and 86%. Our analysis aimed at assessing lifetime prevalence and correlates, and incidence and predictors of induced abortions among FSWs in Kenya.

METHODS

This is a secondary prospective cohort analysis using data collected as part of the WHISPER or SHOUT cluster-randomised trial in Mombasa, assessing effectiveness of an SMS-intervention to reduce incidence of unintended pregnancy. Eligible participants were current FSWs, 16-34 years and not pregnant or planning pregnancy. Baseline data on self-reported lifetime abortion, correlates and predictors were collected between September 2016 and May 2017. Abortion incidence was measured at 6-month and 12-month follow-up. A multivariable logistic regression model was used to assess correlates of lifetime abortion and discrete-time survival analysis was used to assess predictors of abortions during follow-up.

RESULTS

Among 866 eligible participants, lifetime abortion prevalence was 11.9%, while lifetime unintended pregnancy prevalence was 51.2%. Correlates of lifetime abortions were currently not using a highly effective contraceptive (adjusted OR (AOR)=1.76 (95% CI=1.11 to 2.79), p=0.017) and having ever-experienced intimate partner violence (IPV) (AOR=2.61 (95% CI=1.35 to 5.06), p=0.005). Incidence of unintended pregnancy and induced abortion were 15.5 and 3.9 per 100 women-years, respectively. No statistically significant associations were found between hazard of abortion and age, sex work duration, partner status, contraceptive use and IPV experience.

CONCLUSION

Although experience of unintended pregnancy remains high, lifetime prevalence of abortion may have decreased among FSW in Kenya. Addressing IPV could further decrease induced abortions in this population.

Intentional abortion and its associated factors among female sex workers in Iran: Results from national bio-behavioral surveillance-2020

Purpose

In addition to estimating the prevalence of intentional abortion in Iranian female sex workers (FSWs), this study identified related factors using the data of a national study.

Methods

This cross-sectional study utilizes the third round of integrated bio-behavioral surveillance-III data in Iranian FSWs in December 2019 and August 2020, and 1515 Participants were selected in 8 geographically diverse cities in Iran. Logistic regression was performed using unweighted analysis to identify factors associated with intentional abortion. Stata software (version 14), respondent-driven sampling analyses, and R (version 4.1.2) was used for data analysis.

Results

From 1390 participants with valid responses to the abortion question, 598 (37.3%; 95% CI: 32.43, 42.11%) reported intentional abortion during their life. According to the age groups, the highest prevalence of abortion was in the age group of 31 to 40 years (42.60%). In the multivariate logistic regression model, the marital status (divorced women (AOR = 2.05, 95% CI: 1.29, 3.27), concubines (AOR = 1.78, 95% CI: 1.02, 3.11)), work experience in brothels (AOR = 1.39, 95% CI: 1.04, 1.84), the type of sex (AOR = 2.75, 95% CI: 1.35, 5.58), the history of sexual violence (AOR = 1.54, 95% CI: 1.19, 2.01), and alcohol consumption (AOR = 1.53, 95% CI: 1.18, 2.01) were significantly associated with a history of intentional abortion.

Conclusion

Intentional abortion’s prevalence among Iranian FSWs has been much higher than that of the general female population in Iran, which is an alarming issue in the public health of this group and needs more effective interventions. In addition, alcohol consumption, working in a brothel, and being divorced are essential factors in increasing abortions among sex workers.

At the intersection of sexual and reproductive health and HIV services: use of moderately effective family planning among female sex workers in Kampala, Uganda

Background

Female sex workers are vulnerable to HIV, sexually transmitted diseases, and unintended pregnancies; however, the literature on female sex workers (FSW) focuses primarily on HIV and is limited regarding these other health issues.

Methods

We conducted a respondent-driven sampling (RDS) survey during April-December 2012 to characterize the reproductive health of and access to contraceptives FSW in Kampala, Uganda. Eligibility criteria included age ≥ 15 years, residence in greater Kampala, and having sold sex to men in ≤ 6 months. Data were analyzed using RDS-Analyst. Survey logistic regression was used in SAS.

Results

We enrolled 1,497 FSW with a median age of 27 years. Almost all FSW had been pregnant at least once. An estimated 33.8% of FSW were currently not using any form of family planning (FP) to prevent pregnancy; 52.7% used at least moderately effective FP. Among those using FP methods, injectable contraception was the most common form of FP used (55.4%), followed by condoms (19.7%), oral contraception (18.1%), and implants (3.7%). HIV prevalence was 31.4%, syphilis prevalence was 6.2%, and 89.8% had at least one symptom of a sexually transmitted disease in the last six months. Using at least a moderately effective method of FP was associated with accessing sexually transmitted disease treatment in a stigma-free environment in the last six months (aOR: 1.6, 95% CI: 1.1–2.4), giving birth to 2–3 children (aOR: 2.5, 95% CI: 1.4–4.8) or 4–5 children (aOR: 2.9, 95% CI: 1.4–5.9). It is plausible that those living with HIV are also less likely than those without it to be using a moderately effective method of FP (aOR: 0.7, 95% CI: 0.5–1.0).

Conclusions

The provision of integrated HIV and sexual and reproductive health services in a non-stigmatizing environment has the potential to facilitate increased health service uptake by FSW and decrease missed opportunities for service provision.

Congenital Upper Limb Deficiency with Oligodactyly: A Case Report

Congenital upper limb deficiency care and management have undergone drastic changes over the past 50 years. Given the low incidence of this defect nationwide, this case report adds to the existing database to analyze the etiological investigations, descriptive epidemiology, and trend detection. We present a case of a 2-month-old male child with congenital upper limb deficiency and explore the possible etiologies and difficulties during early diagnosis of such rare disorders in a low and middle-income countrries and present implications at the primary health care level to improve the prognosis. Poor nutrition during pregnancy due to an unplanned pregnancy is a possible cause. The prognosis is unfavourable due to sociocultural barriers. To address these limitations, it is pertinent to address disability-adequate knowledge among communities, promote early diagnosis, and timely rehabilitation using a multidisciplinary approach. Further, we provide a framework to optimize care.

Sexualized Drug Use Among Female Sex Workers from Eight Cities in China: A Cross-Sectional Study

There is a rich literature on sexualized drug use (i.e., drug use before or during sex) for men who have sex with men but less data from female sex workers (FSW), particularly from low- and middle-income countries. We describe the sexual and reproductive health outcomes in FSW reporting sexualized drug use. In 2019, we conducted a cross-sectional study in eight cities from seven provinces in China. We recruited FSW through community organizations working with sex workers and included those aged 18 years or above, exchanged sex at least once for money or goods in the past three months, and had traded sex for longer than a year. Multivariable logistic regression models were used. In total, 650 women participated: average age was 38.8 years (SD 10.2), 57.1% reported a monthly income over 5000 RMB ($USD 707), and 12.8% completed high school or above. Among participants, 65 (10.0%, 95% confidence interval (CI) 7.8-12.6) reported a history of sexualized drug use. Compared to FSW who never reported a history of sexualized drug use, FSW who reported a history of sexualized drug use had greater odds of working for a manager compared to being self-employed (adjusted odds ratio (AOR) 4.04, 95% CI 2.12-7.69), work in a sauna (AOR 2.43, 95% CI 1.09-5.41), charging a higher price for vaginal sex (AOR 2.15, 95% CI 1.14-4.06), and ever diagnosed with STIs (AOR 4.51, 95% CI 2.61-7.80). One in ten FSW reported sexualized drug use. Although they had similar risk profiles in terms of consistency of condom use and reproductive health outcomes, these women were more likely to report past STIs than those who reported no sexualized drug use. Health workers who work with substance users should devote attention to the sexual practices of their clients to make sure that they have safer sex.

Women Who Sell Sex in Eastern and Southern Africa: A Scoping Review of Non-Barrier Contraception, Pregnancy and Abortion

Objectives: There is a need to hone reproductive health (RH) services for women who sell sex (WSS). The aim of this review was to collate findings on non-barrier contraception, pregnancies, and abortion amongst WSS in Eastern and Southern African (ESA). Methods: A scoping review methodology was employed. Inclusion criteria were: 1) empirical papers from 2) ESA, 3) published since 2010, and 4) addressing WSS in relation to 5) the identified RH issues. Results: Reports of rates of non-barrier contraceptive usage varied from 15% to 76%, of unintended pregnancy from 24% to 91%, and of abortion from 11% to 48%. Cross-cutting factors were alcohol use, violence, health systems problems, and socio-economic issues. Pregnancy desire was associated with having a non-paying partner. Barriers to accessing, and delaying, antenatal care were reported as common. Targeted programmes were reported as promoting RH amongst WSS. Conclusion: Programmes should be contextually relevant, based on local patterns, individual, interpersonal and systemic barriers. Targeted approaches should be implemented in conjunction with improvement of public health services. Linked HIV and RH services, and community empowerment approaches are recommended.

Unmet Need for Contraception Among Female Sex Workers Initiating Oral Pre-Exposure Prophylaxis for HIV Prevention During Kenya's National Scale-Up: Results From a Programmatic Surveillance Study

Background

Female sex workers (FSWs) experience a higher risk for both HIV acquisition and unwanted pregnancies compared to women in the general population. Pre-exposure prophylaxis (PrEP) for HIV prevention offers protection against HIV infection but has no contraceptive effect. We examined the determinants of unmet need for contraception among FSWs who initiated PrEP to inform programs and policies to optimize contraceptive services and avert unwanted pregnancy among this high-risk group.

Materials and Methods

A cross-sectional analysis was conducted on routine, de-identified client data from a large-scale PrEP service delivery project, from February 2017 to December 2019. Data were collected from FSWs during clinic visits using Ministry of Health approved tools. Records for all 17,456 FSWs initiated on PrEP from 79 health facilities in 10 counties across three geographic clusters with high and medium HIV incidence were examined for eligibility for the analysis. Unmet need for non-barrier contraception was defined as not being pregnant, not currently using the non-barrier contraceptive method, and not trying to conceive or intending to have a child in the near future. Univariate and multivariable regression analyses were conducted with selected variables to examine associations.

Results

In the 79 sites, eligible records from 17,063 FSWs who initiated PrEP were included. Two-thirds were under 30 years, and the majority were not married and had received PrEP at drop-in centers. Overall, the unmet need for non-barrier contraception was 52.6%, higher for those under 20 years of age (60.9%) and those served in public and private health facilities (67.4 and 83.2%, respectively) rather than drop-in centers (50.6%). Women from the Nairobi and Coast cluster regions reported a higher unmet need for contraception compared to those from the Lake region. All these associations were significant (p < 0.05) at the multivariate level.

Conclusions

The high unmet need for non-barrier contraception among FSWs initiating PrEP highlights the need for integrated delivery of contraception services within PrEP programs. Identifying groups with a high unmet need could lead to higher success in an integrated program. Two recommended approaches include training healthcare providers to deliver clear contraception messaging during PrEP initiation and making a range of contraceptives accessible within PrEP services for high-risk groups. Furthermore, accelerated research on multipurpose prevention technologies is necessary to reduce the burden on individuals using multiple prevention products concurrently.

Increased condom use among key populations using oral PrEP in Kenya: results from large scale programmatic surveillance

Background

Female sex workers (FSW) and men having sex with men (MSM) in Kenya have high rates of HIV infection. Following a 2015 WHO recommendation, Kenya initiated national scale-up of pre-exposure prophylaxis (PrEP) for all persons at high-risk. Concerns have been raised about PrEP users' potential changes in sexual behaviors such adopting condomless sex and multiple partners as a result of perceived reduction in HIV risk, a phenomenon known as risk compensation. Increased condomless sex may lead to unintended pregnancies and sexually transmitted infections and has been described in research contexts but not in the programmatic setting. This study looks at changes in condom use among FSW and MSM on PrEP through a national a scale-up program.

Methods

Routine program data collected between February 2017 and December 2019 were used to assess changes in condom use during the first three months of PrEP in 80 health facilities supported by a scale-up project, Jilinde. The primary outcome was self-reported condom use. Analyses were conducted separately for FSW and for MSM. Log-Binomial Regression with Generalized Estimating Equations was used to compare the incidence proportion (“risk”) of consistent condom use at the month 1, and month 3 visits relative to the initiation visit.

Results

At initiation, 69% of FSW and 65% of MSM reported consistent condom use. At month 3, this rose to 87% for FSW and 91% for MSM. MSM were 24% more likely to report consistent condom use at month 1 (Relative Risk [RR], 1.24, 95% Confidence Interval [CI], 1.18–1.30) and 40% more likely at month 3 (RR, 1.40, 95% CI, 1.33–1.47) compared to at initiation. FSW were 15% more likely to report consistent condom use at the month one visit (RR, 1.15, 95% CI, 1.13–1.17) and 27% more likely to report condom use on the month 3 visit (RR 1.27, 95% CI, 1.24–1.29).

Conclusion

Condom use increased substantially among both FSW and MSM. This may be because oral PrEP was provided as part of a combination prevention strategy that included counseling and condoms but could also be due to the low retention rates among those who initiated.

Reproductive Health Concerns of Women With High Risk Sexual Behaviors

Introduction

Expansion of reproductive health services and addressing its different aspects in national and international levels is an important step towards ensuring family and public health. Female sex workers are a vulnerable population that are exposed to high risk sexual behaviors and increased incidence of co-morbid health problems. This study aims to identify the concerns of women with high risk sexual behaviors. Clarifying different aspects of reproductive health and its problems in female sex workers can assist relevant authorities to plan and intervene on reproductive health and to provide more effective solutions on this issue.

Methods

A qualitative study was conducted using a conventional content analysis approach. Snowball sampling was performed in 20 volunteer women with high risk sexual behaviors through in-depth semi-structured interviews conducted in drop-in centers, triangle centers, etc. The data were analyzed through conventional content analysis using the MAXQDA software.

Results

Five main categories and 13 subcategories emerged during the interviews. The main categories included violence, fear, and lack of knowledge, stigma, and psychological problems. Women with high risk sexual behaviors have several reproductive health concerns, including unwanted pregnancy, abortion, STIs (Sexually transmitted infections), HIV, etc. In addition, different types of violence and threats against women, intimidation, objectification, stigma, unresponsiveness of counselling centers, patriarchal culture, gender inequality, etc. were observed in these women.

Conclusion

The study revealed that women in this study experienced deep problems of reproductive health and little attention is paid to them by authorities. Proper planning and appropriate solutions should be provided to solve the problems of these women and the society.

Barriers and motivators of contraceptive use among young people in Sub-Saharan Africa: A systematic review of qualitative studies

BACKGROUND

In sub-Saharan Africa, about 80% of young women either use a traditional method or do not use any form of contraception at all. The objectives of this review were to ascertain the barriers and motivators of contraceptive use among young people in Sub-Saharan Africa.

MATERIALS AND METHODS

We conducted electronic literature searches in PubMed, EMBASE, Ebsco/PsycINFO and Scopus. We identified a total of 4,457 publications and initially screened 2626 based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A total of 13 qualitative studies were retained for the final analysis based on the Joanna Briggs criteria for assessing qualitative studies. The systematic review is registered on PROSPERO with identifier CRD42018081877.

RESULTS

Supportive social networks, respect for privacy and confidentiality, ready availability, affordability and accessibility of contraceptives, as well as the desire to prevent unintended pregnancy and sexually transmitted infections were the motivators of contraceptive use among young people in sub-Saharan Africa. Despite these motivators, myriad of personal, societal, and health systems-based barriers including myths and misconceptions, known side effects of contraceptives, prohibitive social norms, and negative attitude of health professionals were the major barriers to contraceptive use among young people.

CONCLUSION

Sub-Saharan African countries with widespread barriers to contraceptive use among young people may not be able to achieve the Sustainable Development Goal 3.8 target of achieving health for all by the year 2030. Interventions intended to improve contraceptive use need to be intersectoral and multi-layered, and designed to carefully integrate the personal, cultural, organizational and political dimensions of contraception.

Brief Report: Incidence and Correlates of Pregnancy in HIV-Positive Kenyan Sex Workers

INTRODUCTION

The incidence of pregnancy in female sex workers (FSWs) living with HIV is not well characterized.

METHODS

Current and former FSWs living with HIV and enrolled in a prospective cohort study in Mombasa, Kenya, were followed monthly to ascertain sexual behavior and underwent quarterly pregnancy testing. Pregnancies were considered planned, mistimed, or unwanted according to fertility desires and pregnancy intentions. Cox proportional hazards models were used to estimate hazard ratios (HRs) of the association between characteristics and incident pregnancy.

RESULTS

Two hundred seventy-nine FSWs were eligible (October 2012-April 2017). Most women had a nonpaying, regular partner (83.2%, 232/279), were not using modern nonbarrier contraception (69.5%, 194/279), and did not desire additional children (70.6%, 197/279). Of 34 first incident pregnancies [5.8/100 person-years (p-y); 95% confidence interval (CI): 4.1 to 8.0], 91.2% (n = 31) were unintended. The incidences of planned (5.7/100 p-y, n = 3), mistimed (10.4/100 p-y, n = 9), and unwanted pregnancies (4.9/100 p-y, n = 22) were similar (P = 0.15). In univariable analysis, oral contraceptive pill use (versus no contraception), having a nonpaying, regular partner, transactional sex, vaginal washing, condomless sex, and higher sex frequency were associated with an increased pregnancy risk. Older age was associated with a lower pregnancy risk. In multivariable analysis, having a nonpaying, regular partner (adjusted HR 4.0, 95% CI: 1.2 to 14.1) and age ≥40 years (aHR 0.2, 95% CI: 0.0 to 0.9) remained significantly associated with a higher and lower pregnancy risk, respectively.

CONCLUSION

In this cohort of HIV-positive FSWs, most pregnancies were unintended. Identifying FSWs' fertility desires and pregnancy intentions could facilitate efforts to increase contraceptive use and implement safer conception strategies.

Economic and social dimensions influencing safety of induced abortions amongst young women who sell sex in Zimbabwe

Globally, women, experience inequities in access to safe abortion services and this is most acutely felt in country contexts where legal abortions are highly restricted. Data around abortion amongst young women who sell sex (YWSS) in sub-Saharan Africa are very limited. We conducted 30 focus group discussions and 42 in-depth interviews (IDIs) amongst YWSS (16–24 years) in urban and peri-urban areas of Zimbabwe, as well as IDIs amongst 16 peer educators, five health care providers and four key informants. Our findings indicate that abortions occur amongst YWSS in Zimbabwe but there remain questions over the extent of safety of abortions. The restrictive legal context around abortion and illegality of sex work in the country are key determinants underlying the clandestine nature of abortions. Socioeconomic concerns are key in decision-making around abortions. Youth, cost and lack of referral networks contribute towards unsafe abortions, even when safe abortion services are available. Many YWSS are not aware of the availability of post abortion care (PAC) services and resort to self-administered PAC. Being young and selling sex combine and interact on the economic and social levels to produce vulnerabilities greater than their sum to experiencing unsafe abortion.

Effect of a mobile phone intervention for female sex workers on unintended pregnancy in Kenya (WHISPER or SHOUT): a cluster-randomised controlled trial

BACKGROUND

Female sex workers in low-income and middle-income countries face high risks of unintended pregnancy. We developed a 12-month, multifaceted short messaging service intervention (WHISPER) for female sex workers in Kenya who had the potential to become pregnant, to improve their contraceptive knowledge and behaviours. The aim of this study was to assess the effectiveness of the intervention to reduce the incidence of unintended pregnancy among sex workers in Kenya compared with an equal-attention control group receiving nutrition-focused messages (SHOUT).

METHODS

Our two-arm, cluster-randomised controlled trial was done in sex-work venues in two subcounties of Mombasa, Kenya (Kisauni and Changamwe). Participants, aged 16-34 years, not pregnant or planning pregnancy, able to read text messages in English, residing in the study area, and who had a personal mobile phone with one of two phone networks, were recruited from 93 randomly selected sex-work venues (clusters). Random cluster allocation (1:1) to the intervention or control group was concealed from participants and researchers until the intervention started. Both groups received text messages in English delivered two to three times per week for 12 months (137 messages in total), as well as additional on-demand messages. Message content in the intervention group focused on promotion of contraception, particularly long-acting reversible contraception and dual method contraceptive use; message content in the control group focused on promotion of nutritional knowledge and practices, including food safety, preparation, and purchasing. The primary endpoint, analysed in all participants who were randomly assigned and attended at least one follow-up visit, compared unintended pregnancy incidence between groups using discrete-time survival analysis at 6 and 12 months. This trial is registered with Australian New Zealand Clinical Trials Registry, ACTRN12616000852459, and is closed to new participants.

FINDINGS

Between Sept 14, 2016, and May 16, 2017, 1728 individuals were approached to take part in the study. Of these, 1155 were eligible for full screening, 1035 were screened, and 882 were eligible, enrolled, and randomly assigned (451 participants from 47 venues in the intervention group; 431 participants from 46 venues in the control group). 401 participants from the intervention group and 385 participants from the control group were included in the primary analysis. Incidence of unintended pregnancy was 15·5 per 100 person-years in the intervention group and 14·7 per 100 person-years in the control group (hazard ratio 0·98, 95% CI 0·69-1·39).

INTERPRETATION

The intervention had no measurable effect on unintended pregnancy incidence. Mobile health interventions, even when acceptable and rigorously designed, are unlikely to have a sufficient effect on behaviour among female sex workers to change pregnancy incidence when used in isolation.

"I did not plan to have a baby. This is the outcome of our work": a qualitative study exploring unintended pregnancy among female sex workers

BACKGROUND

High number of unintended pregnancies-often leading to induced abortions-are reported among female sex workers (FSWs), highlighting a major unmet need for contraception. To better understand barriers to contraceptive use, we explored FSW's pregnancy perceptions and experiences of unintended pregnancy. We hypothesized that sex work exacerbates barriers to contraceptive use and that FSW's pregnancy perceptions and experiences of unintended pregnancy influence future commitment to contraceptive use.

METHODS

We conducted in-depth interviews with 11 FSWs (January-June 2019) in Dar es Salaam, Tanzania. We purposively sampled FSWs with a positive pregnancy test from those participating in a HIV vaccine preparedness cohort. We used open ended questions to explore how FSWs make decisions when facing barriers to contraceptive use, dealing with unintended pregnancy and adhering to contraceptive use after experiencing unintended pregnancy. All interviews were conducted in Kiswahili, audio-recorded, transcribed and translated into English. Grounded theory approach was used to analyse transcripts. Open and selective coding was performed using Nvivo software.

RESULTS

FSWs reported that sex work impedes good contraceptive behaviour because sex workers felt unable to negotiate consistent condom use, avoided health services due to stigma, missed monthly contraceptive supplies because of inconvenient clinic operating hours or skipped contraceptive pills when intoxicated after taking alcohol. FSWs who perceived pregnancy to be a burden terminated the pregnancy because of fear of loss of income during pregnancy or child rearing expenses in case child support was not assured by their partners. FSWs who perceived pregnancy to be a blessing decided to keep the pregnancy because they desired motherhood and hoped that children would bring prosperity. Family planning counselling and availability of contraceptives during postpartum care influenced the initiation of contraception among FSWs. Financial hardships related to childrearing or painful abortion experiences influenced FSWs' commitment to good contraceptive practices.

CONCLUSION

Our results demonstrate that FSWs face barriers to initiating and adhering to contraceptive use because of sex work stigma, inability to negotiate condoms and failure to access medical services at their convenience. Our findings underscore the need to integrate contraceptive services with HIV programs serving FSWs in their areas of work.

Overview and factors associated with pregnancies and abortions occurring in sex workers in Benin

Background

Behavioural and structural factors related to sex work, place female sex workers (FSWs) at high risk of maternal mortality and morbidity (MMM), with a large portion due to unintended pregnancies and abortions. In the African context where MMM is the highest in the world, understanding the frequency and determinants of pregnancy and abortion among FSWs is important in order to meet their sexual and reproductive health needs.

Methods

Data from two Beninese cross-sectional surveys among FSWs aged 18+ (2013, N = 450; 2016, N = 504) were merged. We first performed exploratory univariate analyses to identify factors associated with pregnancy and abortion (p < 0.20) using Generalized Estimating Equations with Poisson regression and robust variance. Multivariate analyses first included all variables identified in the univariate models and backward selection (p ≤ 0.05) was used to generate the final models.

Results

Median age was 39 years (N = 866). The proportion of FSWs reporting at least one pregnancy during sex work practice was 16.4%, of whom 42.3% had more than one. Most pregnancies ended with an abortion (67.6%). In multivariate analyses, younger age, longer duration in sex work, previous HIV testing, having a boyfriend and not using condoms with him were significantly (p < 0.05) associated with more pregnancies.

Conclusion

One FSW out of five had at least one pregnancy during her sex work practice. Most of those pregnancies, regardless of their origin, ended with an abortion. Improving access to various forms of contraception and safe abortion is the key to reducing unintended pregnancies and consequently, MMM among FSWs in Benin.

High HIV and syphilis prevalence among female sex workers in Juba, South Sudan

HIV prevalence is estimated to be 2.7% in South Sudan; however, little is known about the young country’s epidemic. We conducted a respondent-driven sampling biobehavioral survey in Juba of female sex workers (FSW) aged ≥15 years who sold or exchanged sex in the last 6 months to learn more about this population. We enrolled 838 FSW from November 2015 to March 2016 and estimated HIV prevalence to be 37.8%. Prevalence of active syphilis was 7.3%. FSW were from South Sudan and most neighboring countries. Comprehensive knowledge of HIV was 11.1% and 64.2% of FSW had never spoken with an outreach worker. In multivariable analysis, HIV was associated with being from Uganda (aOR: 3.3, 95% CI: 1.7–6.1) or Kenya (aOR: 4.3, 95% CI: 1.5–13.0) versus from South Sudan. Our survey suggests that FSW may play a critical role in South Sudan’s HIV epidemic and highlights the importance of tailoring services to the unique needs of FSW of all nationalities in Juba.

Correlates of pregnancy among Female Sex Workers (FSWs) in semi urban Blantyre, Malawi

Background

Little is known about female sex workers’ (FSWs) reproductive health apart from their being at higher than usual risk of sexually transmitted infections (STIs), including HIV. The aim of this study was therefore to investigate the correlates of pregnancy among FSWs in semi – urban Blantyre in Malawi.

Methods

We used systematic sampling to recruit a total of 200 FSWs in four different study sites in Blantyre. Data were collected through questionnaire interviews. We calculated the mean and standard deviation for continuous covariates and proportions for categorical variables to describe the data. Logistic regression analysis was used to examine the correlates between the outcome variable (pregnancy) and independent variables.

Results

Ninety one (45, 5%) FSWs were between 18 and 24 years. The prevalence of pregnancy was 61% for FSWs born in rural place as compared to 37% for those who were born in town. In multivariate analysis FSWs who reported to value being respected as mothers had 12 times the risk of pregnancy comparing to the ones who did not (AOR: 11.8, 95% CI: [4.56, 30.72] p-value < 0.001). FSWs who reported using condoms inconsistently had five times the risk of pregnancy compared to the ones who did not, (AOR: 5.26, 95% CI: [2.29, 12.08], p-value < 0.001). FSWs who had a request to bear children from steady partners had 5 times the risk of pregnancy comparing to the ones who did not (AOR: 5.07, 95% CI: [2.14, 11.99]). FSWs who reported forgetfulness of contraceptives’ use had 3 times more risk of pregnancy comparing to the ones who did not (AOR: 3.49 CI: [1.29, 9.37], p-value < 0.013).

Conclusion

The study documents a wide range of correlates of pregnancies among FSWs in the study sites. It is important to recognize the child bearing desires and circumstances of FSWs in order to inform health programs responsive to their needs.

A Mobile Phone-Based Sexual and Reproductive Health Intervention for Female Sex Workers in Kenya: Development and Qualitative Study

BACKGROUND

Female sex workers (FSWs) have high rates of both unintended pregnancy and HIV, but few health promotion interventions address their contraceptive needs or other sexual and reproductive health and rights (SRHR) concerns. A broader approach integrates contraceptive promotion with HIV and sexually transmitted infection (STI) prevention and management, alcohol awareness, gender-based violence and rights, and health care utilization. The Women's Health Intervention using SMS for Preventing Pregnancy (WHISPER) mobile phone intervention uses a participatory development approach and behavior change theory to address these high-priority concerns of FSWs in Mombasa, Kenya.

OBJECTIVE

This paper aimed to (1) describe the process of development of the WHISPER intervention, its theoretical framework, key content domains and strategies and (2) explore workshop participants' responses to the proposed intervention, particularly with regard to message content, behavior change constructs, and feasibility and acceptability.

METHODS

The research team worked closely with FSWs in two phases of intervention development. First, we drafted content for three different types of messages based on a review of the literature and behavior change theories. Second, we piloted the intervention by conducting six workshops with 42 FSWs to test and refine message content and 12 interviews to assess the technical performance of the intervention. Workshop data were thematically analyzed using a mixed deductive and inductive approach.

RESULTS

The intervention framework specified six SRHR domains that were viewed as highly relevant by FSWs. Reactions to intervention content revealed that social cognitive strategies to improve knowledge, outcome expectations, skills, and self-efficacy resonated well with workshop participants. Participants found the content empowering, and most said they would share the messages with others. The refined intervention was a 12-month SMS program consisting of informational and motivational messages, role model stories portraying behavior change among FSWs, and on-demand contraceptive information.

CONCLUSIONS

Our results highlight the need for health promotion interventions that incorporate broader components of SRHR, not only HIV prevention. Using a theory-based, participatory approach, we developed a digital health intervention that reflects the complex reality of FSWs' lives and provides a feasible, acceptable approach for addressing SRHR concerns and needs. FSWs may benefit from health promotion interventions that provide relevant, actionable, and engaging content to support behavior change.

Unmet Need for Family Planning and Experience of Unintended Pregnancy Among Female Sex Workers in Urban Cameroon: Results From a National Cross-Sectional Study

Female sex workers (FSWs) in Cameroon have unmet need for effective contraception, and experience of unintended pregnancy and pregnancy termination is common. Reducing barriers to accessing high-quality, voluntary family planning services in FSW-focused community services is a key strategy to promote client-centered care, promote informed choice, reduce unintended pregnancies, and improve quality of life for FSWs.

Background:

Female sex workers (FSWs) in Cameroon commonly have unmet need for contraception posing a high risk of unintended pregnancy. Unintended pregnancy leads to a range of outcomes, and due to legal restrictions, FSWs often seek unsafe abortions. Aside from the high burden of HIV, little is known about the broader sexual and reproductive health of FSWs in Cameroon.

Methods:

From December 2015 to October 2016, we recruited FSWs aged ≥18 years through respondent-driven sampling across 5 Cameroonian cities. Cross-sectional data were collected through a behavioral questionnaire. Modified-robust Poisson regression was used to approximate adjusted prevalence ratios (aPR) for TOP and current use of effective nonbarrier contraception.

Results:

Among 2,255 FSWs (median age 28 years), 57.6% reported history of unintended pregnancy and 40.0% reported prior TOP. In multivariable analysis, TOP history was associated with current nonbarrier contraceptive use (aPR=1.23, 95% confidence interval [CI]=1.07, 1.42); ever using emergency contraception (aPR=1.34, 95% CI=1.17, 1.55); >60 clients in the past month (aPR=1.29, 95% CI= 1.07, 1.54) compared to ≤30; inconsistent condom use with clients (aPR=1.17, 95% CI=1.00, 1.37); ever experiencing physical violence (aPR=1.24, 95% CI=1.09, 1.42); and older age. Most (76.5%) women used male condoms for contraception, but only 33.2% reported consistent condom use with all partners. Overall, 26.4% of women reported currently using a nonbarrier contraceptive method, and 6.2% reported using a long-acting method. Previous TOP (aPR=1.41, 95%CI=1.16, 1.72) and ever using emergency contraception (aPR=2.70, 95% CI=2.23, 3.26) were associated with higher nonbarrier contraceptive use. Recent receipt of HIV information (aPR=0.72, 95% CI=0.59, 0.89) and membership in an FSW community-based organization (aPR=0.73, 95% CI=0.57, 0.92) were associated with lower use nonbarrier contraceptive use.

Conclusions:

Experience of unintended pregnancies and TOP is common among FSWs in Cameroon. Given the low use of nonbarrier contraceptive methods and inconsistent condom use, FSWs are at risk of repeat unintended pregnancies. Improved integration of client-centered, voluntary family planning within community-led HIV services may better support the sexual and reproductive health and human rights of FSWs consistent with the United Nations Declaration of Human Rights.

HIV pre-exposure prophylaxis for female sex workers: ensuring women's family planning needs are not left behind

INTRODUCTION

Female sex workers (FSWs) experience overlapping burdens of HIV, sexually transmitted infections and unintended pregnancy. Pre-exposure prophylaxis (PrEP) is highly efficacious for HIV prevention. It represents a promising strategy to reduce HIV acquisition risks among FSWs specifically given complex social and structural factors that challenge consistent condom use. However, the potential impact on unintended pregnancy has garnered little attention. We discuss the potential concerns and opportunities for PrEP to positively or negatively impact the sexual and reproductive health and rights (SRHR) of FSWs.

DISCUSSION

FSWs have high unmet need for effective contraception and unintended pregnancy is common in low- and middle-income countries. Unintended pregnancy can have enduring health and social effects for FSWs, including consequences of unsafe abortion and financial impacts affecting subsequent risk-taking. It is possible that PrEP could negatively impact condom and other contraceptive use among FSWs due to condom substitution, normalization, external pressures or PrEP provision by single-focus services. There are limited empirical data available to assess the impact of PrEP on pregnancy rates in real-life settings. However, pregnancy rates are relatively high in PrEP trials and modelling suggests a potential two-fold increase in condomless sex among FSWs on PrEP, which, given low use of non-barrier contraceptive methods, would increase rates of unintended pregnancy. Opportunities for integrating family planning with PrEP and HIV services may circumvent these concerns and support improved SRHR. Synergies between PrEP and family planning could promote uptake and maintenance for both interventions. Integrating family planning into FSW-focused community-based HIV services is likely to be the most effective model for improving access to non-barrier contraception among FSWs. However, barriers to integration, such as provider skills and training and funding mechanisms, need to be addressed.

CONCLUSIONS

As PrEP is scaled up among FSWs, there is growing impetus to consider integrating family planning services with PrEP delivery in order to better meet the diverse SRHR needs of FSWs and to prevent unintended consequences. Programme monitoring combined with research can close data gaps and mobilize adequate resources to deliver comprehensive SRHR services respectful of all women's rights.

Use of long-acting reversible contraception in a cluster-random sample of female sex workers in Kenya

OBJECTIVE

To assess correlates of long-acting reversible contraceptive (LARC) use, and explore patterns of LARC use among female sex workers (FSWs) in Kenya.

METHODS

Baseline cross-sectional data were collected between September 2016 and May 2017 in a cluster-randomized controlled trial in Mombasa. Eligibility criteria included current sex work, age 16-34 years, not pregnant, and not planning pregnancy. Peer educators recruited FSWs from randomly selected sex-work venues. Multiple logistic regression identified correlates of LARC use. Prevalence estimates were weighted to adjust for variation in FSW numbers recruited across venues.

RESULTS

Among 879 participants, the prevalence of contraceptive use was 22.6% for implants and 1.6% for intra-uterine devices (IUDs). LARC use was independently associated with previous pregnancy (adjusted odds ratio for one pregnancy, 11.4; 95% confidence interval, 4.25-30.8), positive attitude to and better knowledge of family planning, younger age, and lower education. High rates of adverse effects were reported for all methods.

CONCLUSION

The findings suggest that implant use has increased among FSWs in Kenya. Unintended pregnancy risks remain high and IUD use is negligible. Although LARC rates are encouraging, further intervention is required to improve both uptake (particularly of IUDs) and greater access to family planning services.

Antenatal care presentation and engagement in the context of sex work: exploring barriers to care for sex worker mothers in South Africa

BACKGROUND

Late presentation combined with limited engagement in antenatal care (ANC) increases risk of vertical transmission among mothers living with HIV. Female sex workers (FSW) have more than four times greater burden of HIV than other women of reproductive age in South Africa and the majority of FSW are mothers. For mothers who sell sex and are at increased HIV acquisition risk, timely and routine ANC seeking is especially vital for prevention of vertical transmission. This study represents a mixed-methods study with FSW in Port Elizabeth, South Africa, to characterize factors influencing ANC seeking behaviors in a high HIV prevalence context.

METHODS

FSW (n = 410) were recruited into a cross-sectional study through respondent-driven sampling between October 2014 and April 2015 and tested for HIV and pregnancy. A sub-sample of pregnant and postpartum women (n = 30) were invited to participate in in-depth interviews (IDIs) to explore their current or most recent pregnancy experiences. IDIs were coded using a modified grounded theory approach and descriptive analyses assessed the frequency of themes explored in the qualitative analysis among the quantitative sample.

RESULTS

In the quantitative survey, 77% of FSW were mothers (313/410); of these, two-thirds were living with HIV (212/313) and 40% reported being on antiretroviral therapy (ART) (84/212). FSW in the qualitative sub-sample reported unintended pregnancies with clients due to inconsistent contraceptive use; many reported discovering their unintended pregnancies between 4 and 7 months of gestation. FSW attributed delayed ANC seeking and ART initiation in the second or third trimesters to late pregnancy detection. Other factors limiting engagement in ANC included substance and alcohol use and discontent with previous healthcare-related experiences.

CONCLUSIONS

Late pregnancy discovery, primarily because pregnancies were unplanned, contributed to late ANC presentation and delayed ART initiation, increasing risks of vertical HIV transmission. Given limited ART coverage among participants, addressing the broader sexual and reproductive health and rights needs of mothers who sell sex has important implications for preventing vertical transmission of HIV. Integrating comprehensive family planning services into FSW programming, as well as providing active linkage to ANC services may reduce barriers to accessing timely ANC, decreasing risks of vertical transmission.

Evaluating the vertical HIV transmission risks among South African female sex workers; have we forgotten PMTCT in their HIV programming?

Background

Female sex workers (FSW) have a greater HIV burden compared to other reproductive-aged women and experience high incidence of pregnancies. However, there are limited data on mother-to-child transmission of HIV in the context of sex work. This study assessed the uptake of prevention of mother-to-child transmission (PMTCT) services to understand the vertical HIV transmission risks among FSW in South Africa.

Methods

FSW ≥18 years were recruited into a cross-sectional study using respondent-driven sampling (RDS) between October 2014–April 2015 in Port Elizabeth, South Africa. An interviewer-administered questionnaire captured information on demographics, reproductive health histories, and HIV care, including engagement in PMTCT care and ART. HIV and pregnancy testing were biologically assessed. This analysis characterizes FSW engagement in HIV prevention and treatment cascades of the four prongs of PMTCT.

Results

Overall, 410 FSW were enrolled. The RDS-weighted HIV prevalence was 61.5% (95% bootstrapped confidence interval 54.1–68.0). A comprehensive assessment of the four PMTCT prongs showed gaps in cascades for each of the prongs. In Prongs 1 and 2, gaps of 42% in consistent condom use with clients among HIV-negative FSW and 43% in long-term high efficacy contraceptive method use among HIV-positive FSW were observed. The analyses for prongs three and four pertained to 192 women with children < 5 years; 101/192 knew their HIV diagnosis prior to the study, of whom 85% (86/101) had their children tested for HIV after birth, but only 36% (31/86) of those who breastfed retested their children post-breastfeeding. A substantial proportion (35%, 42/120) of all HIV-positive women with children < 5 years of age were HIV-negative at their last delivery and seroconverted after delivery. Less than half (45%) of mothers with children < 5 years (45/101) were on ART and 12% (12/101) reported at least one child under five living with HIV.

Conclusion

These findings show significant gaps in engagement in the PMTCT cascades for FSW, evidenced by sub-optimal uptake of HIV prevention and treatment in the peri/post-natal periods and insufficient prevention of unintended pregnancies among FSW living with HIV. These gaps result in elevated risks for vertical transmission among FSW and the need for PMTCT services within FSW programs.

Female Sex Workers' Experiences Selling Sex during Pregnancy and Post-Delivery in South Africa

Nearly 75 percent of female sex workers (FSWs) in Port Elizabeth, South Africa are mothers, many of whom engage in sex work during pregnancy or after delivery. We conducted in-depth interviews with 22 postpartum and 8 pregnant FSWs in Port Elizabeth. Interview guides were used to probe women's experiences, challenges, and concerns about selling sex during pregnancy and post-delivery in a high-HIV-prevalence context. Interviews were transcribed, translated, and coded using thematic analysis. FSWs experienced and feared violence by clients during pregnancy, highlighting the need for safe work environments. Further, FSWs expressed concerns about HIV acquisition and vertical transmission during the perinatal period. Physical challenges related to pregnancy affected women's ability to work. Returning to work post-delivery presented barriers to initiating and practicing exclusive breastfeeding. As a result, many FSWs practiced mixed feeding. Interventions, tailored to respond to FSW's challenges and experiences, may offer improved health outcomes in this context.

Incidence of unintended pregnancy among female sex workers in low-income and middle-income countries: a systematic review and meta-analysis

OBJECTIVES

To determine the incidence of unintended pregnancy among female sex workers (FSWs) in low-income and middle-income countries (LMICs).

DESIGN

We searched MEDLINE, PsychInfo, Embase and Popline for papers published in English between January 2000 and January 2016, and Web of Science and Proquest for conference abstracts. Meta-analysis was performed on the primary outcomes using random effects models, with subgroup analysis used to explore heterogeneity.

PARTICIPANTS

Eligible studies targeted FSWs aged 15-49 years living or working in an LMIC.

OUTCOME MEASURES

Studies were eligible if they provided data on one of two primary outcomes: incidence of unintended pregnancy and incidence of pregnancy where intention is undefined. Secondary outcomes were also extracted when they were reported in included studies: incidence of induced abortion; incidence of birth; and correlates/predictors of pregnancy or unintended pregnancy.

RESULTS

Twenty-five eligible studies were identified from 3866 articles. Methodological quality was low overall. Unintended pregnancy incidence showed high heterogeneity (I²>95%), ranging from 7.2 to 59.6 per 100 person-years across 10 studies. Study design and duration were found to account for heterogeneity. On subgroup analysis, the three cohort studies in which no intervention was introduced had a pooled incidence of 27.1 per 100 person-years (95% CI 24.4 to 29.8; I²=0%). Incidence of pregnancy (intention undefined) was also highly heterogeneous, ranging from 2.0 to 23.4 per 100 person-years (15 studies).

CONCLUSIONS

Of the many studies examining FSWs' sexual and reproductive health in LMICs, very few measured pregnancy and fewer assessed pregnancy intention. Incidence varied widely, likely due to differences in study design, duration and baseline population risk, but was high in most studies, representing a considerable concern for this key population. Evidence-based approaches that place greater importance on unintended pregnancy prevention need to be incorporated into existing sexual and reproductive health programmes for FSWs.

WHISPER or SHOUT study: protocol of a cluster-randomised controlled trial assessing mHealth sexual reproductive health and nutrition interventions among female sex workers in Mombasa, Kenya

INTRODUCTION

New interventions are required to reduce unintended pregnancies among female sex workers (FSWs) in low- and middle-income countries and to improve their nutritional health. Given sex workers' high mobile phone usage, repeated exposure to short messaging service (SMS) messages could address individual and interpersonal barriers to contraceptive uptake and better nutrition.

METHODS

In this two-arm cluster randomised trial, each arm constitutes an equal-attention control group for the other. SMS messages were developed systematically, participatory and theory-driven and cover either sexual and reproductive health (WHISPER) or nutrition (SHOUT). Messages are sent to participants 2-3 times/week for 12 months and include fact-based and motivational content as well as role model stories. Participants can send reply texts to obtain additional information. Sex work venues (clusters) in Mombasa, Kenya, were randomly sampled with a probability proportionate to venue size. Up to 10 women were recruited from each venue to enrol 860 women. FSWs aged 16-35 years, who owned a mobile phone and were not pregnant at enrolment were eligible. Structured questionnaires, pregnancy tests, HIV and syphilis rapid tests and full blood counts were performed at enrolment, with subsequent visits at 6 and 12 months.

ANALYSIS

The primary outcomes of WHISPER and SHOUT are unintended pregnancy incidence and prevalence of anaemia at 12 months, respectively. Each will be compared between study groups using discrete-time survival analysis.

POTENTIAL LIMITATIONS

Contamination may occur if participants discuss their intervention with those in the other trial arm. This is mitigated by cluster recruitment and only sampling a small proportion of sex work venues from the sampling frame.

CONCLUSIONS

The design allows for the simultaneous testing of two independent mHealth interventions for which messaging frequency and study procedures are identical. This trial may guide future mHealth initiatives and provide methodological insights into use of reciprocal control groups.

Contraceptive use and unplanned pregnancy among female sex workers in Zambia

Objectives

Access to reproductive healthcare, including contraceptive services, is an essential component of comprehensive healthcare for female sex workers (FSW). Here, we evaluated the prevalence of and factors associated with contraceptive use, unplanned pregnancy, and pregnancy termination among FSW in three transit towns in Zambia.

Study design

Data arose from the baseline quantitative survey from a randomized controlled trial of HIV self-testing among FSW. Eligible participants were 18 years of age or older, exchanged sex for money or goods at least once in the past month, and were HIV-uninfected or status unknown without recent HIV testing (<3 months). Logistic regression models were used to assess factors associated with contraceptive use and unplanned pregnancy.

Results

Of 946 women eligible for this analysis, 84.1% had been pregnant at least once, and among those 61.6% had an unplanned pregnancy, and 47.7% had a terminated pregnancy. Incarceration was associated with decreased odds of dual contraception use (aOR=0.46, 95% CI 0.32–0.67) and increased odds of unplanned pregnancy (aOR=1.75, 95% CI 1.56–1.97). Condom availability at work was associated with increased odds of using condoms only for contraception (aOR=1.74, 95% CI 1.21–2.51) and decreased odds of unplanned pregnancy (aOR=0.63, 95% CI 0.61–0.64).

Conclusions

FSW in this setting have large unmet reproductive health needs. Structural interventions, such as increasing condom availability in workplaces, may be useful for reducing the burden of unplanned pregnancy.

Sexual and reproductive health outcomes among female sex workers in Johannesburg and Pretoria, South Africa: Recommendations for public health programmes

BACKGROUND

The sexual and reproductive health (SRH) status of female sex workers is influenced by a wide range of demographic, behavioural and structural factors. These factors vary considerably across and even within settings. Adopting an overly standardised approach to sex worker programmes may compromise its impact on some sub-groups in local areas.

METHODS

Records of female sex workers attending clinic-, community-, or hotel-based health services in Johannesburg (n = 1422 women) and Pretoria (n = 408 women), South Africa were analysed. We describe the population's characteristics and identified factors associated with sexual and reproductive health outcomes, namely HIV status; previous symptomatic sexually transmitted infection (STI); modern contraceptive use and number of child dependents.

RESULTS

The women in Johannesburg were less likely than those in Pretoria to have HIV (42.2% vs 52.9%), or previous symptomatic STIs (44.3% vs. 8.3%), and were 1.4 fold less likely to have child dependents (20.1% vs. 15.3%). About 43% of women in Johannesburg were Zimbabwean and 40% in Pretoria. Of concern, only about 15% of women in both sites were using modern contraceptives. Johannesburg women were also more likely to access health services at a hotel (85.0% vs. 80.6%) or clinic (5.7% vs. 0.5%), to have completed secondary education (57.1% vs. 36.0%), and moved house more than twice during the past year (19.6 vs. 2.0%). In both cities, risk of HIV rose rapidly with age (23.8%-58.2% vs. 22.0%-64.8%). Of interest, HIV prevalence was considerably higher in those with consistent condom use with one's main partner than inconsistent users.

CONCLUSIONS

Sex worker populations are heterogeneous. Local health programmes must prioritise services that reflect the variety and complexity of sex worker needs and behaviours, and should be designed in consultation with sex workers. Segmenting sex worker populations according to age, country of origin and place of service delivery, and training healthcare providers accordingly, could help prevent new HIV infections, improve adherence to antiretroviral treatment and increase uptake of SRH services.
