Insight into hepatitis B prevalence and risk factors among Vietnamese Americans: a cross-sectional analysis of data from a community-based screening program.

ABSTRACT:

Objectives

The aims of our study were to describe current hepatitis B prevalence among Vietnamese Americans and to examine predictors of hepatitis B risk in this specific ethnic community.

Design

Cross-sectional analysis of data from a community-based screening program.

Setting

This analysis was based on hepatitis screening community events in Southern California.

Participants

2508 Vietnamese Americans in Southern California.

Outcome measures

Serological tests for hepatitis B surface antigen, hepatitis B surface antibody, and total hepatitis B core antibody were used to classify participants as one of four hepatitis B infection statuses: currently infected, previously infected, susceptible, or immune due to a previous hepatitis B vaccination.

Results

Across 2508 participants, 9.0% were currently infected with hepatitis B and 17.7% were at risk for hepatitis B. Females and those reporting a previous hepatitis B vaccination were at significant decreased risk of hepatitis B (OR=0.48, 95%?CI 0.33 to 0.69 and OR=0.53, 95%?CI 0.31 to 0.93, respectively) whereas those born outside of the USA and with a family history of the disease showed substantial increased risk (OR=13.36, 95%?CI 1.62 to 110.05 and OR=4.68, 95%?CI 2.66 to 8.22, respectively). Among those who reported a previous hepatitis B vaccination, less than half (42.9%) possessed the protective antibodies that result from a hepatitis B vaccination.

Conclusions

Vietnamese Americans remain disproportionately burdened by hepatitis B. Public health efforts that focus on improving hepatitis B awareness and vaccination knowledge and that are tailored to specific high-risk subgroups, such as immigrants and those with infected family members, could help in addressing the disease's burden in this high-prevalence population.

Project description:ObjectivesCancer is the leading cause of death among Asian Americans. Chinese Americans comprise the largest Asian American ethnic group. Low health literacy (LHL) is associated with lower cancer screening rates, but this association has not been studied in Chinese Americans. We examined the relationship between LHL and meeting US Preventive Service Task Force (USPSTF) guidelines for cervical, colorectal and breast cancer screening among Chinese Americans.DesignObservational study of Chinese respondents in the 2007 California Health Interview Survey, a population-based survey. Interview languages included English, Cantonese and Mandarin.SettingCalifornia, USA PARTICIPANTS: Chinese respondents in age/gender groupings appropriate for USPSTF cancer screening guidelines (cervical: women ages 21-65, n=632; colorectal: men or women ages 50-75, n=488; and breast: women ages 50-74, n=326).OutcomesRelationships were tested using multivariable logistic regression models controlling for healthcare access and demographic factors, including limited English proficiency (LEP). The combined effects of having both LHL and LEP were specifically examined. LHL was measured by 2-items on perceived ease-of-use of written medical materials. All study variables were self-reported.ResultsCancer screening percentages among Chinese Americans were 77.8% for cervical, 50.9% for colorectal (47.9% for women and 54.2% for men), and 85.5% for breast. LHL was associated with lower odds of meeting breast cancer screening guidelines (OR 0.41; 95% CI 0.20 to 0.82). Respondents with both LHL and LEP were significantly less likely to have up-to-date colorectal (OR 0.49; 95% CI 0.25 to 0.97) and breast cancer screening (OR 0.21; 95% CI 0.08 to 0.54) than those with neither health communication barrier. In all multivariable models, having seen a physician in the past year was a significant predictor of an up-to-date screening.ConclusionsIn Chinese Americans, LHL and LEP were negatively associated with up-to-date breast and colorectal cancer screening, independent of a recent physician visit. Efforts to promote cancer screening among Chinese Americans should consider and address LHL, LEP and physician access barriers.

Project description:ObjectivesWe analysed data collected during programmatic screening activities conducted in 2017 to describe hepatitis C virus (HCV) seroprevalence in the general population and identify associated factors.DesignWe analysed data collected between June and September 2017. For both seroprevalence and viraemia, variations across demographic and geographic factors were assessed and multivariate regression models were fit to identify factors independently associated with each marker. Geospatial data were examined for visualisation.SettingHCV screening was organised within each of the 30 districts in Rwanda. One designated location in each district was selected as the screening site and screening took place for 1 week at each site.ParticipantsThis study included 124 223 male and female volunteers. Anti-HCV-positive individuals were followed up with HCV RNA viral load (VL) testing for infection confirmation.Main outcome measuresTwo markers were examined: the presence of HCV antibodies and HCV RNA VL.ResultsAmong 124 223 individuals screened, 11 003 (8.86%, 95% CIs: 8.70% to 9.02%) were positive for anti-HCV. Anti-HCV prevalence varied by age with the oldest age group (>55 year olds) having a prevalence of 16.46% (95% CIs: 16.14% to 16.80%) and the youngest age group (<25 year olds) having a prevalence of 2.20% (95% CIs: 1.93% to 2.50%) (crude OR=8.78). After adjustment for covariates, an association remained between anti-HCV prevalence and age (p<0.001), province (p<0.001) and socioeconomic status (p<0.001). Of the 3771 anti-HCV-positive individuals who had an available HCV RNA VL result, 2099 (55.66%, 95% CI: 54.06% to 57.25%) had a detectable HCV RNA VL. Age was also associated with HCV viraemia (p<0.001).ConclusionResults suggest that over 55% of individuals who screened positive for HCV-antibodies were chronically infected. Targeted screening for HCV among older individuals is recommended, given the association between age and infection. Further geographical hotspots of HCV infection can also inform targeted screening as Rwanda moves towards HCV elimination.

Project description:The epidemiology of hepatitis C in Cambodia is not well-known. We evaluated the prevalence of hepatitis C virus (HCV) and risk factors in the HIV cohort of Sihanouk Hospital Center of Hope in Phnom Penh to strengthen the evidence for suitable HCV testing strategies among people living with HIV (PLWH) in Cambodia. All consenting adult PLWH without a history of HCV treatment were tested for HCV between November 2014 and May 2016 according to the CDC algorithm (HCV antibody II electro-chemiluminescence immunoassay, followed by COBAS® AmpliPrep/COBAS® TaqMan® HCV PCR and INNO-LIA® HCV Score immunoblot end-testing). Genotyping was performed using the line probe assay Versant HCV genotype 2.0®. The study enrolled a total of 3045 patients (43% males, median age: 42.5 years, <1% high-risk). HCV antibodies were detected in 230 (7.6%; 95% confidence interval [CI] 6.6-8.5). Upon further testing, HCV antibodies were confirmed in 157 (5.2%; 95% CI 4.4-6.0) and active HCV in 106 (3.5%; 95% CI 2.8-4.2). Viremic prevalence peaked among men aged 50-55 years (7.3%) and women aged >55 years (11.2%). Genotype 1b (45%) and 6 (41%) were predominant. Coinfected patients had a higher aspartate-to-platelet ratio index, lower platelets, a lower HBsAg positivity rate and more frequent diabetes. Based on logistic regression, blood transfusion antecedents (adjusted odds ratio 2.9; 95% CI 1.7-4.9), unsafe medical injections (2.0; 1.3-3.2), and partner (3.4; 1.5-7.6) or household member (2.4; 1.3-3.2) with liver disease were independently associated with HCV in women. However, having a tattoo/scarification (1.9; 1.1-3.4) and household member (3.1; 1.3-7.3) with liver disease were associated with HCV in men. Thus, our study found intermediate endemicity of active hepatitis C in a large Cambodian HIV cohort and provides initial arguments for targeted HCV screening (>50 years, partner/household member with liver disease, diabetes, increased aspartate-to-platelet ratio index) as efficient way forward.
