Insights
This study found no link between ABO blood groups and obesity in Saudi Arabia. High rates of obesity were observed, but blood type did not influence weight status.
Area of Science:
- Medical Science
- Genetics
- Public Health
Background:
- ABO blood groups are linked to chronic diseases.
- Previous research suggests a connection between ABO blood type and obesity risk.
Purpose of the Study:
- To investigate the association between ABO blood groups and obesity.
- Study conducted in apparently healthy individuals attending primary healthcare centers in Arar city, Northern Saudi Arabia.
Main Methods:
- Cross-sectional study of 401 participants aged 15+.
- Data collected via interviews and questionnaires.
- Anthropometric measurements (height, weight, BMI) and ABO/Rh blood typing performed.
Main Results:
- Obesity prevalence was high (37.4%), with a mean BMI of 28.56.
- Blood group O was most common (44.1%).
- No statistically significant differences in BMI were found across different ABO blood groups or Rh types.
Conclusions:
- High prevalence of obesity and overweight in the studied population.
- No association found between overweight, obesity, and ABO blood groups or Rh factor.
Introduction:
ABO blood groups are associated with some important chronic diseases. Previous studies have observed an association between ABO blood group and risk for obesity.
Objective:
This study aimed to determine whether there is an association between ABO blood groups and obesity in apparently healthy attendees of primary healthcare (PHC) centers in Arar city, Northern Saudi Arabia.
Participants And Methods:
This cross-sectional study included 401 participants aged 15 years and older attending three randomly selected PHC centers in Arar city. Data were collected by means of personal interview using a predesigned questionnaire. Anthropometric examination included height and weight measurements with calculation of BMI. ABO and Rh blood groups were determined.
Results:
The majority of the participants were female (70.8%). The mean±SD age was 28.6±9.1 years. Only 5.7% were underweight. Both normal and overweight participants were equal in number and constituted 28.4%, whereas obese individuals constituted 37.4% with a mean BMI of 28.56±8.0. Blood group O was the most common (44.1%), followed by A (30.9%), B (18.7%), and AB (6.2%). Rh-positive cases constituted 87.0%. Blood group O was the most common type among the obese individuals (44.7%), followed by A, B, and AB groups (30, 20, and 5.3%, respectively). BMI was highest (28.8±9.2) in blood group O. There were no statistically significant differences between different ABO blood groups as regards BMI, Rh, and sex. Moreover, there was no statistically significant difference between Rh type and BMI.
Conclusion:
The prevalence of obesity and overweight is high in the population attending PHC centers of Arar city, Northern Saudi Arabia. There is no association between overweight, obesity, and ABO blood groups or Rh.
