Background
The association of hypertension and obesity with blood group “B” was reported by many researchers. Recognition of a positive relation with blood group might reflect increased susceptibility to hypertension wich is still required to be explored by new researches.
Aims
to determine the frequency of different blood groups among blood transfusion post donors and find the association of blood groups and body mass index with blood pressure.
Methods
this cross-sectional study was performed at blood donors transfusion post, from january 2018 to December 2019, participants were divided into groups on the basis of their ABO blood groups, rhesus D and on body mass index criteria. Blood groups were determined by simple conventional slide method. Blood pressure was estimated by manual auscultatory technique with a mercury sphygmomanometer. Data was analysed using SPPS .16
Results
there were 2883 blood donors with an overall mean age of 37± 10,27 years (range : 17-66 years), 288 female and 2595 male, sex-ratio M/F = 9,01. Blood group O was the predominant group (1284→44,5%), besides, 2561 (89%) subject were rhesus positive. The overall mean values for weight, height and BMI were : 80±14.49 kg (50-150), 173.07 ± 7.50 (150-198) and 27,13 ± 4,42 kg/m² (16.01-54.09): according to the blood group and BMI, our donors are distributed as follows: blood group A (+): n= 891, the average BMI = 27,12 ± 4,46 kg/m² (17,28- 50,78), A (-): n= 103, the average BMI is = 18,40 ± 5,02 kg/m² (18,3- 54,69), blood group AB (-): n= 22, the average BMI = 26,78 ± 2,23 kg/m² (20,68- 34,66), blood group AB (+): n=116, the average BMI = 26,69± 4,26 kg/m² (17,99- 39,63), blood group B (-): n= 47, the average BMI = 26,90 ± 5,16 kg/m² (18,29- 39,27), blood group B (+): n= 420, the average BMI = 26,97 ± 4,34 kg/m² (17,36- 44,44), blood group O (-): n= 145, the average BMI = 27,01 ± 4,66 kg/m² (18,59- 44,18), blood group O (+): n= 1139, the average BMI = 27,14 ± 4,72 kg/m² (16,07- 46,30). Moreover 314 subjects (1%) were pre-hypertensive: blood group A: n= 184 (6%), blood group AB: n=26 (0,9%), blood group B: n=79 (2,7%), blood group O: n= 25 (0,9%). Relative risk of hypertension for obese was grater than non obese : AUC=0.459 (p=0.009), body mass index was associated with both systolic pressure (p=0.001), on the other hand, in our study, no significant differences were observed in the mean SBP (systolic blood pressure) and diastolic blood pressure (DBP) among the ABO study groups: AUC : 0,276, p=0.067 and AUC = 0, 429, p=0,156 for the two evaluations respectively
Conclusion
blood group O was the most common blood group, it is strongly correlated with the risk of obesity, but in contrast to some researches, regression analysis of the present data did not find any significant association of blood groups with DBP and SBP
