Abstract

The ABO blood group system was divided into four phenotypes i.e., A, B, AB, and O following its discovery by Karl Landsteiner in 1990. Antigens of the ABO blood group can be found in bodily fluids such as the salivary and digestive fluids. Furthermore, People are classified as ``secretors'' or ``non-secretors'' based on their ability to secrete (ABO blood group) antigens in body fluids. The control-based study was conducted on 342 Iraqi adults who were presented at educational institutions. The study lasted from October 2022 to February 2023 and aimed to determine the relationship between secretor status with (gender, blood groups, and body mass index). The results showed that the females are non-secretors which are lower than in males but this difference is not significant. While, non-secretors are those who have non-O blood groups (A, B, and AB), which is significantly higher than of those in the secretors' group. In contrast, about half of secretors have O blood group, which is significantly higher than only a quarter of non-secretors. Furthermore, there is no significant difference in the distribution of blood groups based on the Rh system. In addition, there are no significant differences in the frequency of normal, overweight, and obese cases between secretors and non-secretors.
