Non-barrier contraceptive use and relation to condom use behaviour by partner type among female sex workers in Andhra Pradesh, India

Social and structural determinants associated with the prevalence of sexually transmitted infections among female commercial sex workers in Dhaka City, Bangladesh

Female commercial sex workers (FCSWs) bear higher rates of sexually transmitted infections (STIs) among key populations. The association of structural determinants and STIs among FCSWs was not at the forefront of research earlier in Bangladesh. This study examined how structural factors correlate with the prevalence of STIs at physical/social/economic/policy levels among FCSWs in Dhaka city. 495 FCSWs were screened for HIV, hepatitis B, and syphilis. Structural variables (Individual risks, high-risk sexual behaviors, work environments) were extracted from the previous multi-level study on FCSWs and analyzed in 2020 to determine whether macro/micro-structural factors were associated with STIs. The prevalence of STIs was 43.6% (95% CI: 39.1%-48). Most (n = 207/495) FCSWs were infected with Syphilis or Hepatitis B, only 1.8% had co-infection, and none was positive for HIV. Multiple logistic regression revealed that 'Individual risk' factors like age (≤18 years, adjusted odds ratio = AOR = .28; 18.1-29.9 years, AOR = .57), years in the sex industry (<1 year AOR = .15; 1-5 years, AOR = .39), and condoms as contraceptives (AOR = 2.7) were significantly associated with STIs. Considering 'High-risk behaviors' like monthly coitus with regular clients (AOR = .33), performing no anal sex ever (AOR = .03), and consistent condom use (AOR = .13) were less likely to be associated with STIs (P<0.05), while the association of ever group sex with STIs reported to double (AOR = 2.1). 'Work environment' like sex on roads/parks/shrines/markets (AOR = 2.6) and ever HIV-testing (AOR = 2.5) were significantly linked with STIs. However, micro-level factors like experiencing forced sex in the past year (AOR = 1.79) and condoms collected from hotel boys (AOR = .34) were significantly associated with STIs in the 'Hierarchical- model' with increasing model-power. 'Micro-structural' determinants predominated over 'Macro/policy-level factors' and profoundly influenced STIs. FCSWs need comprehensive and integrated interventions to promote accurate condom use perception, eliminate risky sexual behaviors, and provide quality reproductive health care. Necessary steps at the policy level are urgently needed to decriminalize commercial sex work.

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.

Factors associated with the uptake of long-acting reversible contraception among female sex workers in post-conflict Northern Uganda: a cross-sectional study

BACKGROUND

Long-acting reversible contraception (LARC) is the most effective and reliable contraception option for female sex workers (FSWs) who desire future fertility. Unlike the other reversible contraceptive methods, LARC use requires only periodic users' involvement at the time of application and re-application. However, only a few studies on LARC uptake among FSWs are available in Uganda. To fill this knowledge gap, we examined factors associated with the uptake of LARC among FSWs in post-conflict Northern Uganda.

METHODS

We conducted a cross-sectional study among adult FSWs operating in the post-conflict Gulu district in Northern Uganda. We collected quantitative data among 280 FSWs of reproductive ages (18-49 years) who were neither pregnant nor using permanent contraception. We utilized a pretested semi-structured questionnaire to gather information from each participant through face-to-face interviews. We collected data on socio-demographic characteristics, sex work-related characteristics, obstetric history, HIV status, and LARC uptake. Data were then entered into EPI INFO 7, cleaned, and analyzed using multivariable Poisson regression in STATA 14.0 to obtained adjusted prevalence ratios (PR).

RESULTS

Among the study participants: the mean age (SD, range) was 26.5 (5.9, 18-45) years, 48.6% reported at least one unintended pregnancy during sex work, and 37.4% had at least one induced abortion. Meanwhile, only less than two in three (58.6%) participants were using LARC. At multivariable level, factors that remained independently associated with LARC uptake included: longer duration of sex work (adjusted PR = 1.44, 95% CI: 1.03-2.02), higher parity (adjusted PR = 1.13, 95% CI: 1.02-1.26), history of unintended pregnancies during sex work (adjusted PR = 1.24 CI: 1.01-1.51), and being a brothel/lodge-based FSWs (adjusted PR = 1.28, 95% CI: 1.01-1.63).

CONCLUSIONS

The above findings revealed a gap in the uptake of LARC among FSWs in post-conflict Northern Uganda influenced by duration of sex work, parity, unintended pregnancies during sex work, and place of sex work. Interventions to improve LARC uptake should target the newly recruited FSWs with low parity and the non-brothel/lodge-based FSWs.

Unweighted regression models perform better than weighted regression techniques for respondent-driven sampling data: results from a simulation study

Background

It is unclear whether weighted or unweighted regression is preferred in the analysis of data derived from respondent driven sampling. Our objective was to evaluate the validity of various regression models, with and without weights and with various controls for clustering in the estimation of the risk of group membership from data collected using respondent-driven sampling (RDS).

Methods

Twelve networked populations, with varying levels of homophily and prevalence, based on a known distribution of a continuous predictor were simulated using 1000 RDS samples from each population. Weighted and unweighted binomial and Poisson general linear models, with and without various clustering controls and standard error adjustments were modelled for each sample and evaluated with respect to validity, bias and coverage rate. Population prevalence was also estimated.

Results

In the regression analysis, the unweighted log-link (Poisson) models maintained the nominal type-I error rate across all populations. Bias was substantial and type-I error rates unacceptably high for weighted binomial regression. Coverage rates for the estimation of prevalence were highest using RDS-weighted logistic regression, except at low prevalence (10%) where unweighted models are recommended.

Conclusions

Caution is warranted when undertaking regression analysis of RDS data. Even when reported degree is accurate, low reported degree can unduly influence regression estimates. Unweighted Poisson regression is therefore recommended.

More comprehensive reporting of methods in studies using respondent driven sampling is required: a systematic review of the uptake of the STROBE-RDS guidelines

BACKGROUND

Respondent-driven sampling (RDS) is an increasingly popular method of recruiting participants from hard-to-reach populations and has traditionally been used to estimate the prevalence of HIV among marginalized people. The STROBE-RDS guidelines were published in 2015 to improve the reporting of these studies. We aim to determine the current applications of RDS and the quality of reporting of these studies.

METHODS

The SCOPUS, PubMed, and CINAHL databases were used to find papers published in 2017, relating to RDS. Papers meeting the inclusion criteria of cross-sectional studies using RDS were classified according to the study outcome and target population. A random sample of 25 papers was selected to evaluate the quality of reporting using the STROBE-RDS guidelines.

RESULTS

Men who have sex with men, people who inject drugs, and female sex workers were the most common populations for RDS studies; over half of the studies examined the HIV epidemic. Quality of reporting is good with respect to the original STROBE guidelines but is generally weaker with respect to RDS-specific aspects of the study, including recruitment and statistical analysis.

CONCLUSION

Most authors are using RDS appropriately and aware of the need for statistical adjustments to RDS data. Nonetheless, the STROBE-RDS guidelines should be more widely disseminated to promote better reporting of key aspects of RDS studies.

Single Mothers and Female Sex Workers in Zambia Have Similar Risk Profiles

The aim of the study was to compare reproductive health and high-risk behaviors in female sex workers (FSWs) and single mothers (SMs) in Zambia's two largest cities, Lusaka and Ndola. FSWs were invited from known community hot spots, and sexually active HIV- SMs were referred from infant vaccination services for free and anonymous screening and treatment for HIV and other sexually transmitted infections (STIs) and long acting reversible contraception. A subset completed an interviewer-administered survey. From 2012 to 2016, 1,893 women (1,377 FSWs and 516 HIV- SMs) responded to referrals. HIV prevalence was 50% in Lusaka and 33% in Ndola FSWs. Positive syphilis serology (rapid plasmin reagin) was found in 29%-31% of HIV+ FSWs and 9%-12% of HIV- FSWs and SMs. Trichomonas was more common in Ndola (11%-12%), compared with Lusaka (3%-7%). Antiretroviral therapy (ART) use among HIV+ FSWs was 9%-15%. In all groups, consistent condom use (8%-11%) and modern contraceptive use (35%-65%) were low. Low literacy and reported coercion at first sexual intercourse were common in both FSWs and SMs, as was alcohol use during sex among FSWs. Zambian FSWs and SMs have low condom use and high HIV/STI and unplanned pregnancy risk. Many FSWs and half of SMs are ≥25 years of age, and thus too old for HIV prevention services targeting "adolescent girls and young women" (aged 15-24). Tailored and targeted reproductive health services are needed to reduce HIV, STI, and unplanned pregnancy in these vulnerable women.

Meeting the Reproductive Health Needs of Female Key Populations Affected by HIV in Low- and Middle-Income Countries: A Review of the Evidence

Female sex workers and other women at high risk of acquiring HIV have the right to sexual and reproductive health, including the right to determine the number and timing of pregnancies. We conducted a literature review to examine the data that exist regarding the family planning and reproductive health needs of female key populations, the underlying determinants of these populations' vulnerability to poor reproductive health outcomes, and the obstacles they face in accessing high-quality reproductive health services. Findings indicate that female key populations experience high rates of unmet need for family planning and safer conception services, unintended pregnancies, sexual violence, and abortion, and that they practice inconsistent condom use. Restrictive policy environments, stigma and discrimination in health care settings, gender inequality, and economic marginalization restrict access to services and undermine the ability to safely achieve reproductive intentions. We offer recommendations for structural, health system, community, and individual-level interventions that can mitigate the effects of these barriers and improve reproductive health outcomes.
