“…The prevalence of HBsAg in our study is alike in the studies reported in Libya 1.5%, in Algeria 1.6% [17], in Mexico 1.65% [18], in Amritsar (India) 1.19% [19], in Isfahan (Iran) (1.56%) [20] and in Bulgaria 2.26% [21]. However, the prevalence of HBsAg in the present study is higher than the studies reported in Lorestan West of Iran (0.7%) [22], in India (0.9%) [23], in Punjab (Northern India) (1.1%) [24], and in Peshawar, Pakistan (1.16%) [25].…”

Introduction: Hepatitis B infection is a serious global public health problem. The aim of the study was to assess the seroprevalance of hepatitis B surface antigen (HBsAg), as well as the risk factors associated with hepatitis B virus (HBV) infection among pregnant women attending antenatal care clinics of the University Hospital in Antioch, Turkey. Methodology: This descriptive cross-sectional study was carried out between May 2016 and December 2016. The Chi-squared was utilized to estimate the statistical significance of the association between socio-demographic variables and HBsAg status. The results were generated as proportions odds ratio (OR) with their 95% confidence intervals (Cl) and calculated by using both univariate and multivariate logistic regression analysis. Results: The seroprevalence of HBsAg was found to be 2.1%. A significant association was observed between age and HBsAg seropositivity (p = 0.027). History of blood transfusion (AOR = 9.51, 95% CI = 1.92-46.80, p = 0.006), history of hepatitis (AOR = 11.13, 95% CI = 2.02-61.28, p = 0.006), tattooing (AOR = 13.64, 95% CI = 2.52-73.76, p = 0.002) and a history of household/close contact (AOR = 11.10, 95% CI = 1.56-78.65, p = 0.016) were significantly associated with the risk of HBV infection. Conclusions: Data regarding the seroprevalence of HBsAg and risk factors associated with HBV infection in pregnant women plays a crucial role in evaluating the effectiveness of the public health protection policies and the strategies to control the disease.

“…39 In contrast, higher seroprevalence of HBV was observed in similar study populations in different parts of the world. For instance; the current study finding is considerably higher than other previous study reports such as: 2.26% from Bulgaria, 40 2.78% from Pakistan, 41 2.04% from India, 42 4.6% from Nigeria 43 and 3.5% from Dawuro, Southern Ethiopia. 26 These differences in the seroprevalence might be due to differences in cultural and behavioral characteristics of the pregnant women.…”

“…The prevalence of serological markers of HBV among participants aged 30–39 years was two times higher than the prevalence in those aged 18–29 years. The same trend was observed for anti-HBc in the Moscow region [ 11 ] and for HBsAg among pregnant women in Bulgaria [ 30 ], but it was not observed in surveys from Nigeria, China, India, and the Lao People’s Democratic Republic [ 16 , 31 , 32 , 33 ].…”

Russia had a high incidence of hepatitis B virus (HBV) infection before the vaccination campaigns of 1997, 2001, 2007, which targeted newborns, adolescents, and adults, respectively. The aim of our study was to assess the prevalence of serological markers of HBV infection, associated factors, and vaccination status among young adults in Arkhangelsk, Northwest Russia. In this cross-sectional, population-based study, we used a quota sampling method to recruit 1243 adults aged 18–39 years. Participants completed a self-administrated questionnaire and were tested for hepatitis B markers. Associations between positivity for markers and selected sociodemographic and behavioral factors were studied by logistic regression. 10.9% of our participants were positive for at least one marker of hepatitis B, 1.2% were positive for HBsAg, and 42.1% were negative for all markers. In multivariable logistic regression analyses, age 30–34 years; lack of self-reported vaccination; and having ≥2 sexual partners in the last 6 months were associated with positivity for markers of hepatitis B. Hepatitis B vaccination was confirmed in 46.9% of participants. Although half of our study sample was vaccinated, four in 10 were still susceptible to infection and more than one participant in 100 showed evidence of an active infection.
