[Effects of lifestyle on hematologic parameters; I. Analysis of hematologic data in association with smoking habit and age].
The effects of smoking and age on the results of hematologic tests were determined in a group of 429 healthy male workers. The results obtained were as follows: 1) The values of total leucocyte count (x10(9)/l), neutrophil count (x10(9)/l), lymphocyte count (x10(9)/l), monocyte count (x10(9)/l), hemoglobin (g/l), hematocrit, mean corpuscular volume (MCV; fl), mean corpuscular hemoglobin (MCH; pg), and mean corpuscular hemoglobin concentration (MCHC; g/dl) in current smokers were significantly higher than those in non-smokers. 2) Total leucocyte counts and neutrophil counts significantly increased with the number of cigarettes smoked per day in current smokers. 3) Total leucocyte counts, neutrophil counts, and lymphocyte counts significantly increased with Brinkman Index (B.I.) in current smokers. 4) The increase of age was significantly associated with the decrease of erythrocyte counts and the increase of MCV in both current smokers and non-smokers.
