They are related to diseases like cardiovascular diseases, cerebral thromboembolism. ABO blood group system may influence coagulation factor VIII which may increase the future risk of thrombosis. <strong>Aim:</strong> To assess the relation of ABO blood group with coagulation factor VIII in healthy adults.<strong> Material and Methods: </strong>A prospective type of analytical cross-sectional study was conducted in the Department of Physiology, Dhaka Medical College, Dhaka from July 2019 to June 2020. After obtaining ethical clearance, a total of 190 healthy adults were selected from different areas of Dhaka city based on inclusion and exclusion criteria, with ages ranging from 18 - 45 years. The subjects were interviewed and detailed history regarding personal, family, medical and drug were taken. Prior to sample collection, informed written consent was taken from the participants. Individuals of blood group A were selected as group A, blood group B as group B, blood group AB as group AB and blood group O as group O. Coagulation factor VIII was measured in the Department of Hematology and BMT Unit, Dhaka Medical College Hospital, Dhaka. Blood grouping was done in the Department of Physiology, Dhaka Medical College, Dhaka. <strong>Statistical Analysis:</strong> For statistical analysis, ONE way ANOVA followed by Bonferroni test were considered using SPSS 25.0 version. <strong>Results: </strong>In this study, blood group B was most common (33.2%). Coagulation factor VIII was significantly higher (p < 0.001) in blood group A (105.76% ± 11.82%), B (112.00% ± 15.02%), AB (109.80% ± 11.93%) than blood group O (82.00% ± 12.86%). No significant difference was observed among A, B and AB blood groups regarding coagulation factor VIII. <strong>Conclusions:</strong> It can be concluded that blood group A, B, AB individuals may have more chance of thrombosis due to significantly higher coagulation factor VIII than blood group O individuals.展开更多

Methods: Participants were 18 - 21 years old and African American/Hispanic Black. Focus group sessions were conducted with a discussion guide. Thematic analysis was used to analyze results. Results: Five focus groups were conducted. Four major themes emerged: My Culture Matters, The Effects of Slavery are Still Present, Meet Me Where I Want to Be, Not Where Society Wants Me, and If They Have Been Fat, They Get Me. It is clear that weight programs need to be sensitive to cultural preferences. Conclusion: Our results present unique factors related to overweight/obesity in the Black community.展开更多
