A Health Belief Model Examination of Factors Related to Hepatitis B Screening Among African Immigrants in Philadelphia.

Chronic hepatitis B infection is a leading cause of liver cancer worldwide. In the USA, African immigrants (AI) have high hepatitis B virus (HBV) infection rates but low HBV knowledge and screening rates. Research about HBV among AI living in Philadelphia is particularly limited. This study aims to assess barriers to and factors influencing HBV screening in the Philadelphia AI population. African and Caribbean-born adults in Greater Philadelphia were recruited for phone interviews at community health fairs hosted by the African Cultural Alliance of North America (ACANA) and the African Family Health Organization (AFAHO) in partnership with the Hepatitis B Foundation. Seventeen interviews were recorded, transcribed, and coded independently by two members of the research team using NVivo software. Themes and subthemes were created by analysis of the codes and arranged under Health Belief Model (HBM) concepts. Major perceived barriers included lack of HBV knowledge and awareness and cultural challenges related to health care access, preventive care, fear, and stigma. Participants recommended using community organizations and programs to spread awareness about HBV and serve as cues to action. In-person education was emphasized due to lack of access to and knowledge of technology such as Zoom. While HBV educational sessions have been implemented in this population, they have not been consistent or far-reaching. The results of this study can contribute to the implementation of a comprehensive AI-specific HBV education and screening program through partnerships with community organizations to ensure that all high-risk individuals in the Philadelphia area are screened.

The PNPLA3 rs738409 Variant but not MBOAT7 rs641738 is a Risk Factor for Nonalcoholic Fatty Liver Disease in Obese U.S. Children of Hispanic Ethnicity.

PURPOSE: The rs641738 C>T in membrane-bound O-acyltransferase domain-containing protein 7 (MBOAT7) is implicated, along with the rs738409 C>G polymorphism in patatin-like phospholipase domain-containing protein 3 (PNPLA3), in nonalcoholic fatty liver disease (NAFLD). The association of these polymorphisms and NAFLD are investigated in Hispanic children with obesity. METHODS: Obese children with and without NAFLD were enrolled at a pediatric tertiary care health system and genotyped for MBOAT7 rs641738 C>T and PNPLA3 rs738409 C>G. NAFLD was characterized by the ultrasonographic presence of hepatic steatosis along with persistently elevated liver enzymes. Genetic variants and demographic and biochemical data were analyzed for the effects on NAFLD. RESULTS: Among 126 enrolled subjects, 84 in the case group had NAFLD and 42 in the control group did not. The two groups had similar demographic distribution. NAFLD was associated with abnormal liver enzymes and elevated triglycerides and cholesterol (p<0.05). Children with NAFLD had higher percentage of PNPLA3 GG genotype at 70.2% versus 31.0% in non-NAFLD, and lower MBOAT7 TT genotype at 4.8% versus 16.7% in non-NAFLD (p<0.05). PNPLA3 rs738409 C>G had an additive effect in NAFLD; however, MBOAT7 rs641738 C>T had no effects alone or synergistically with PNPLA3 polymorphism. NAFLD risk increased 3.7-fold in subjects carrying PNPLA3 GG genotype and decreased in MBOAT7 TT genotype. CONCLUSION: In Hispanic children with obesity, PNPLA3 rs738409 C>G polymorphism increased the risk for NAFLD. The role of MBOAT7 rs641738 variant in NAFLD is less evident.
