Change of complete blood count parameters according to blood type and smoking

In this study, it was aimed to investigate the change in the parameters of complete blood count depending on blood type and smoking status. The individuals were grouped according to their blood group type and status of cigarette use, and the statistical differences in their levels of Neutrophil/Lymphocyte ratio (NLR), Platelet/Lymphocyte ratio (PLR), and Mean Platelet Volume/Lymphocyte ratio (MPVLR) were evaluated.3119 individuals participated in the study. 26.67% of them were smokers. According to the ABO blood group system, 44.47% of the participants had type A, 32.48% had type O, 16.09% had type B, and 6.96% had type AB. 88.81% of the participants were Rh(+) and 11.19% of them were Rh(-). The NLR, PLR, and MPVLR of the smokers were higher than those of the non-smokers. The participants’ NLR, PLR, and MPVLR levels showed statistically significant differences depending on ABO and Rh blood groups. This difference was seen to arise from ARh (+) individuals. The NLR, PLR, and MPVLR levels were the highest in ARh (+) individuals and the lowest in the ABRh (-) individuals. The NLR, PLR, and MPVLR values were the highest in the ARh (+) smokers and the lowest in ABRh (-) non-smokers. It was found that there were significant differences in the participants’ blood count parameters depending on blood type and smoking status. This may imply that ARh (+) individuals who smoke have higher parameters than those who have other blood groups and do not smoke, which may be beneficial in predicting the risk of chronic inflammation-related diseases.
