“…In selection bias, seven articles [18,20,32,[37][38][39][40] were rated "strong" because those study participants were factory workers, and more than 80% of the selected individuals agreed to participate. Six articles [19,31,[33][34][35][36] were rated "medium" because only 60-79% of the selected individuals agreed to participate. In study design, two studies [31,37] were randomized controlled trials (RCTs), so they were rated "strong", and eleven studies [18-20, 32-36, 38-40] were cohort studies, so they were rated "medium".…”

“…Four studies conducted educational intervention combined with community intervention [34][35][36]40]. Three studies demonstrated that educational intervention combined with community intervention reduced the proportion of workers with casual sex (from 12.0% to 6.1%, P = 0.03 [34]; from 17.5% to 3.5%, P < 0.001 [35]; from 8.8% to 4.6%, P < 0.01 [36]). Two studies showed a decrease in the proportion of workers having sex with sex workers [34,35], but only one report [35] had statistically signi cant result (from 11.2% to 0.75%, P < 0.001 [35]).…”

Background: Factory workers in low- and middle-income countries (LMICs) are vulnerable to HIV transmission. Interventions are needed to prevent HIV in this population. We systematically reviewed published literature on the efficacy of various HIV interventions in reducing stigma, risk behaviors and HIV transmission among factory workers.Methods: A systematic review was performed using predefined inclusion and exclusion criteria. Four databases (PubMed, PsycINFO, Scopus and EMBASE) were searched for relevant publications between January 1, 1990 and December 31, 2018. Two independent reviewers assessed the methodological quality of studies.Results: Thirteen articles were included, with 2 randomized controlled trials and 11 cohort studies. Five interventions and their combinations were summarized. Educational intervention increased condom use and reduced the use of recreational drugs and alcohol before sex. Community intervention that proactively provide HIV counselling and testing (HCT) services could increase the detection rate of HIV and other sexually transmitted diseases (STDs). Lottery intervention increased HCT uptake and decreased HIV public stigma. Education combined with community intervention reduced the proportion of workers with casual sex and enhanced HIV knowledge. Peer education combined with community intervention increased the proportion of workers who were willing to take their partners to HCT. Policy intervention combined with peer education enhanced HIV knowledge, perceived condom accessibility and condom use with regular partners.Conclusions: Various interventions improved HIV knowledge, decreased HIV stigma and reduced HIV-related risk behaviors among factory workers in LMICs. The combination of multiple interventions tended to achieve better efficacy than a single intervention. Persistent combination interventions are essential to address HIV in this population.

“…avoiding the progression of the disease in infected people by providing early health care and psychosocial support), as it encompasses counselling before and after HIV testing. Several studies conducted in resource-limited settings have demonstrated that VCT may be effective at preventing HIV infection and other STIs in some populations, including FSWs, serodiscordant couples and pregnant women [7][8][9][10][11][12][13]. Moreover, in a predominantly heterosexual transmission context, a VCT programme targeting high-prevalence groups with high numbers of partners such as FSWs can be very efficient in reducing the spread of HIV to the general population displaying a lower prevalence [14].…”

“…1 Figures on prevalence and incidence of syphilis in several studies from sub-Saharan Africa are based on commonly used serological screening assays. [2][3][4][5][6] However, the interpretation of non-treponemal and treponemal specific serological tests in a population where syphilis and HIV are endemic, is encountered with difficulty. [7][8][9] The rapid plasma reagin (RPR) test is a non-treponemal serological test for syphilis widely used as a screening test in antenatal clinics and other health facilities in the developing world.…”

Objectives: To assess the performance of routine syphilis screening during 5 year follow up of Ethiopian factory workers, participating in a cohort study on HIV/AIDS. Methods: Syphilis serology test results of factory workers, who each donated at least six blood samples were evaluated. Screening in 1997-8 had been performed by the Treponema pallidum particle agglutination (TPPA) assay and in 1999-2001 by the rapid plasma reagin (RPR) test. TPPA had been followed by RPR or RPR by TPPA, in case of a positive screening result. Samples of study subjects showing inconsistent sequential TPPA and/or RPR results were retested independently by three laboratory technicians. Results: A total of 540 cohort participants (8.3% HIV positive at enrolment) donated 4376 blood samples (mean 8.3 per subject). From 93 of the 176 participants with at least one positive TPPA result during follow up, 152 samples were retested by RPR and/or TPPA. Based on the revised syphilis test results, the 540 cohort participants were classified as having no (70.5%), past (20.6%), prevalent (6.9%), or incident (2.0%) syphilis. The RPR screening test was difficult to interpret and yielded 8.2% biological false positive (BFP) RPR results, or 3.2% if weak positive results were excluded. There was no correlation between HIV infection and BFP RPR reactions. Sample mix-ups were detected in 1.2%. Conclusion: Evaluation of routine syphilis screening as performed in a long term cohort study on HIV/AIDS in Ethiopia showed difficulties encountered in syphilis screening programmes such as a high percentage of BFP RPR, inconsistencies in interpretation of the RPR test, and sample mix ups. The findings stress the need to develop a syphilis screening assay that is easy to perform and interpret and to implement quality assurance programmes.
