“…We do not have information on comorbidity for this dataset. Among the few previous work, [2] did not find an association between ABO blood type and obesity in a Saudi Arabian dataset; [14] found blood type B (followed by O) to be a risk for both hypertension and obesity in an India dataset; [22] depicted a more complicated picture that a potential association of blood type with obesity may depend on both gender and age; etc. As hypertension and obesity are known risk for hospitalization, even if there were information on these comobidities in our data, it would not help to explain our conclusion through the “guilty by association” artifact.…”

“…Antigens of the ABO blood group are found on a variety of human cells, including vascular endothelial cells and brain cells, in addition to red blood cells. 1 Links between blood group and a wide range of diseases, including obesity, 42 preeclampsia, 43 gestational diabetes, 44 gastric cancer, and cardiovascular disorders have been identified. 1 In addition, ABO blood group-related susceptibility to various viral infections, including with hepatitis B, influenza viruses, and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), have been shown in several studies.…”

Relationships of ABO and Rhesus blood groups with type 2 diabetes mellitus: a systematic review and meta-analysis

et al. 2022

Objectives The susceptibility to type 2 diabetes mellitus (T2DM) has been linked to blood type. We aimed to characterize the relationships of the ABO and Rhesus blood groups with T2DM. Methods Literature searches were performed using the Medline, PubMed, Scopus, Cochrane, EMBASE, and Google Scholar databases to identify studies published up to 31 March 2022. The PRISMA guidelines were used for reporting. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were obtained using fixed-effects models. Results Twenty-six studies of 6870 patients with T2DM and 11,879 controls were identified. Compared with the other ABO groups, people with blood type B were at higher risk of T2DM (OR: 1.30, 95% CI: 1.20–1.41), while group O was associated with a lower risk (OR: 0.92, 95% CI: 0.86–0.98). There were no significant associations of T2DM with blood types A or AB, or Rh factor. Conclusion Individuals with blood type B are at higher risk of developing T2DM. Therefore, they should be screened for T2DM on a frequent basis and be made aware of the importance of maintaining a balanced diet and regular exercise for the prevention of obesity and T2DM. PROSPERO registration number CRD42022353945.

“…Recent research investigated the link between blood grouping and obesity [11,24]. In a previous study conducted in Brazil with 549,690 individuals, Flor et al found a gender-specific link between particular ABO antigens and BMI [25]. The O and B blood types were connected with a higher frequency of obesity in females compared to males.…”

“…Blood types B and O were associated with a higher frequency of obesity in females. The O and B blood types were associated with a lower incidence of obesity in males [25]. Another study by Chandra et al reported that patients with blood group type B followed by blood type O patients were more likely to be obese compared to others [11].…”

Blood Group and Response to Bariatric Surgery in Morbidly Obese Patients: A Retrospective Study in Saudi Arabia

et al. 2022

Objectives: To explore the relationship between the blood group of patients and their response to bariatric surgery and to identify predictors of better outcomes. Methods: This was a retrospective cross-sectional analysis of patients who underwent laparoscopic sleeve gastrectomy for morbid obesity between 2014 and 2020 at King Saud University Medical City in Riyadh, Saudi Arabia. Results: This study included 1434 individuals. The mean change in BMI (pre- versus post-BMI) differed statistically significantly between blood groups (p ≤ 0.01). The greatest drop in body weight was seen in individuals with the AB-negative blood type (56.0 (21.4) kg), which corresponds to the greatest percentage of reduction from baseline (47.7% (14.8)). The mean BMI of the patients decreased by 34.7% (9.2) from a mean pre-operation BMI of 45.5 (8.4) kg/m2 to 29.7 (6.1) kg/m2 (p ≤ 0.001). After laparoscopic sleeve gastrectomy, male patients and those with the B-negative blood type are more likely to see a greater BMI reduction (pre-operation compared to post-operation) (p ≤ 0.05). Conclusions: For morbidly obese patients, laparoscopic sleeve gastrectomy demonstrated promising weight loss outcomes. Blood groups may be able to predict the success rate of bariatric surgery in morbidly obese patients.
