Effects of smoking on healthy young men’s hematologic parameters

Abstract

OBJECTIVE:Cigarette smoking carries higher risks for most of the chronic diseases. It also has chronic and acute effects on the hematologic system. This study explores the effects of cigarette smoking on some blood values of the healthy young male smokers.METHODS:In this study, cigarette smoking and usage of substance, additional diseases, birth places, and education levels of 171 healthy male subjects between the ages of 20 and 30 years were investigated. Anthropometric measurements of the cases were obtained. Thyroid function tests, vitamin B12, folic acid, ferritin, ferrous/ıron, total ıron binding capacity, leucocytes, platelets, hemoglobin, hematocrit, mean corpuscular volume (MCV), mean platelet volume (MPV), HBs AG, Anti-HBs and Anti-HIV were evaluated. Groups of smokers and nonsmokers were compared. The group of smokers was also sorted into subgroups of “2 year-smokers”, “5 year-smokers” and “10 year-smokers” according to their pack-years of smoking. The effects of pack-years of smoking on the blood values were also investigated.RESULTS:The MCV values of the group of smokers were higher than the values of nonsmokers, which were statistically significant (p<0.05). As a result of the subgroup analyses of smokers, the white blood cell (WBC) counts of the individuals smoking for 5 or more years were significantly higher than those with a history of smoking less than 5 years, (p<0.05).CONCLUSION:This study supports the idea that cigarette smoking and especially longer durations of smoking have adverse effects on the hematologic parameters.

Hematological Changes Associated with Illicit Drug Abuse in A City of Northern Nigeria

“…This may be due to increased MCV (macrocytosis). This concurs with the findings of Basime and colleagues who reported higher PCV values among abusers as against non-non-abusers [16] . However, this is in contrast with findings by…”

“…Many of the reports on the effects of substance abuse on hematological changes are done severally on substances including marijuana, alcohol, cigarette and volatile substances [14][15][16][17] . This is particularly true on the effects of excessive cigarette smoking on increased packed cell volume/ poor red cell indices.…”

“…This is particularly true on the effects of excessive cigarette smoking on increased packed cell volume/ poor red cell indices. Heavy alcohol consumption leads to bone marrow malfunctioning while volatile substances such as () leads to basophilia and eosinophilia [14][15][16][17] .…”

Recent Advancements in Robot Assisted Lower Limb Rehabilitation Techniques

“…Following spinal cord injury (SCI), stroke, muscle disorder, and post operation such as total knee arthroplasty, patients need rehabilitation to regain their movement capability (mobilization) [2][3][4][5][6][7][8]. The number of individuals in need of rehabilitation is steadily increasing day by day.…”
