Seroprevalence and risk factors of hepatitis B and C virus infections in female workers of Lao garment factories.

ABSTRACT: The prevalence of hepatitis B and C virus infections may be higher in vulnerable populations or in individuals likely to be exposed through risk behaviors such as female garment factory workers in Lao People's Democratic Republic. A cross-sectional study was performed on 400 female garment workers in Vientiane Capital. Women were tested for hepatitis B virus surface antigen and antibodies against hepatitis B core, surface antigen and hepatitis C virus using commercial Enzyme-linked immuno-absorbent assays. Participants completed a standardized questionnaire about potential risk factors for both infections. Sixteen women (4±1.9%) were HBsAg carriers, 187 (47%) had anti-HBc, 116 (29%) anti-HBs and 7 (1.8±1.3%) anti-HCV antibodies. Three factors were significantly associated with the presence of anti-HBc (indicating previous exposure to HBV): (i) residence in dormitories, (ii) more than one sexual partner, (iii) history of abortion. Despite a high risk of exposure, the prevalence of anti HBV and anti HCV infection markers in this sample of female workers was not higher than in the Lao general population. Our data suggest that exposure to HBV happens later during life and was significantly associated with sexual risk behavior. Thus, this study highlights the vulnerability of these women who were mostly young, uneducated, unvaccinated, of rural origin and were not aware of the risk of infections. An occupational health program targeting the female factory workers should be implemented in Lao PDR.

Project description:BackgroundHepatitis B and C virus infections are endemic diseases in sub-Saharan Africa, the region with the highest prevalence of these infections in the world. Female sex workers are exposed to sexually transmitted infections, including hepatitis B and C, because of their high-risk sexual behavior and limited access to health services. There are no large-scale data on the prevalence of hepatitis B and C virus infections among female sex workers in Ethiopia, a critical gap in information this study aimed to fill.MethodsThis was a cross-sectional, biobehavioral survey conducted from December 2019-April 2020 among 6085 female sex workers aged ≥15 years and residing in sixteen (16) regional capital cities and selected major towns of Ethiopia. Blood samples were collected from the participants for hepatitis B and C virus serological testing. The data were collected using an open data kits (ODK) software and imported into STATA version16 for analysis. Descriptive statistics (frequencies and proportions) were used to summarize data on the study variables. Bivariable and multivariable logistic regression analyses were conducted to determine the strength of association between independent variables (risk factors) and the outcome (hepatitis B and C virus infection). Adjusted Odd ratio (AOR) was used to determine independent associations, 95% confidence interval to assess precision of the estimates, and a P value ≤ 0.05 to determine statistically significant.ResultsThe prevalence of hepatitis B and C infections among the 6085 female sex workers was 2.6% [(95% CI (2.2,2.8)] and 0.5% [(95% CI (0.4,0.7)], respectively. Female sex workers who had 61-90 and ≥91 paying clients in the past six months [(AOR = 1.66; 95% CI, (0.99, 2.79); P = 0.054] and [(AOR = 1.66 95% CI, (1.11, 2.49); P = 0.013], respectively, age at first sex selling of 20-24 and >25 years [(AOR = 1.67; 95% CI, (1.14, 2.44); P = 0.009)] and [(AOR = 1.56; 95% CI (1.004, 2.43); P = 0.048)], respectively, known HIV positive status [(AOR = 1.64; 95% CI (1.03, 2.62); P = 0.036] were significantly associated with the prevalence of hepatitis B virus infection. Similarly, hepatitis C was significantly associated with, age at first sex ≤15 years and age 16-20 years [(AOR = 0.21; 95%CI (0.07,0.61); P = 0.005)] and [(AOR = 0.18; 95% CI (0.061, 0.53); P = 0.002)], respectively, known HIV positive status [(AOR = 2.85; 95%CI (1.10,7.37); P = 0.031)] and testing positive for syphilis [(AOR = 4.38; 95% CI (1.73,11.11); P = 0.002)], respectively.ConclusionThis analysis reveals an intermediate prevalence of hepatitis B and a low prevalence of hepatitis C infection among female sex workers in Ethiopia. It also suggests that population groups like female sex workers are highly vulnerable to hepatitis B, hepatitis C, and other sexually transmitted infections. There is a need for strengthening treatment and prevention interventions, including immunization services for hepatitis B vaccination, increasing HCV testing, and provision of treatment services.

Project description:BackgroundThe prevalence of intimate partner violence (IPV) is high (54%) in Bangladesh. Moreover, female garment workers report higher rates of IPV and are also vulnerable to workplace violence (WPV). Experience of violence puts women at increased risk of developing depressive symptoms, which are related with low self-esteem, lower life satisfaction and lower productivity. To our knowledge, there has been no previous research on depression among female garment workers and its connections to IPV and WPV in Bangladesh. This paper aims to address this gap by studying the relationship of IPV, WPV and depression among female garment workers.MethodsThe data for this paper comes from a cross-sectional survey of female garment workers (n = 800) conducted as baseline survey of a quasi-experimental study known as HERrespect. Survey data were collected during September-December, 2016 among randomly selected female garment workers from eight garment factories in and around Dhaka city. Structural equation modelling was conducted to explore the relationship among IPV, WPV and depression.ResultsThe findings show high rates of any IPV (69%); WPV (73%, experienced or witnessed) and depressive symptomatology (40%) among female garment workers. The analysis of pathways shows that IPV impacts a woman's experience of WPV and work related stress leading to the development of depression; while WPV had direct and mediated pathways to depression. Experience of controlling by their husband leads to WPV and increased work related stress, and thus leads to depression. It also reveals that a worker's ability to mobilize resources in emergency, however, increased self-esteem and reduced work related stress.ConclusionThis study shows the pathways through which experience of IPV and WPV lead to development of depressive symptoms among female garment workers. The link between women's ability to mobilize resources with self-esteem and work related stress indicates the need for socio-economic empowerment of women and may suggest that combined intervention to address IPV and women's empowerment could be successful in dealing with WPV and mental health.
