Tobacco smoking and blood parameters in the kurdish population of Iran

Abstract

Objective This study investigates the relationship between smoking and blood parameters in the Iranian Kurdish population. Method The current study was conducted based on the recruitment phase of the Ravansar Non-Communicable Disease (RaNCD) cohort study. Results Current smokers had higher levels of RBC count, HCT, HGB, MCV, MCH, MCHC, WBC count, and GR%, than in other groups significantly. Passive smokers had higher levels of PLT count and PCT statistically. The increasing exposure time of smoking positively affected WBC count, GR%, PLT count, PCT, and RDW in female passive smokers. In addition, heavy smokers, as well as participants with a higher duration time of smoking, had the same results for significantly lower levels of lymphocyte and monocyte and a higher level of RBC indices. Conclusion According to the present study, along with the current smokers, the intensity of smoking, as well as the duration time of the smoke, could have a positive correlation with blood parameters. Furthermore, passive smokers and specifically secondhand female smokers were more vulnerable to smoke.

Smoking is associated with increased eryptosis, suicidal erythrocyte death, in a large population-based cohort

“…However, our results are not indicative of anemia in smokers since erythrocyte count and other hematological parameters of smokers were not significantly different from those of non-smokers. However, we could not fully confirm the results from observational studies demonstrating higher red blood cell count, hematocrit, hemoglobin, and MCV in smokers than in non-smokers 9 , 10 . In line with those studies, we found moderately higher MCH and MCHC in smokers, in particular in those smoking a high number of cigarettes per day.…”

“…Although smoking has cytotoxic and hypoxic effects, there is comparatively limited data on the relationship between smoking and the red blood cell system. Interestingly, a few observational studies found tobacco smoking associated with higher red blood cell indices such as red blood cell count, hematocrit, hemoglobin, and mean corpuscular volume (MCV) 9 , 10 . On the other hand, in vitro data indicate that smoking causes erythrocyte death.…”
