RESUMO
A group of 572 young cadets from the General Military Academy in Zaragoza (AGEMZA) with a mean age of 19.9 years was studied in two different situations: on admission to the AGEMZA, when physical activity was very intensive (A) and after 8 months, by which time they had all received identical diets and physical activity was considerably reduced (B). On both occasions they were asked about their smoking habits and their personal and family histories. Their height and weight were recorded and a sample of venous blood was taken to determine the lipid, biochemical and haematological profiles. We found that more smokers had a family history of sudden death or acute myocardial infarction than the non-smokers. The smokers also showed a lower HDL cholesterol level (54.3 +/- 9.8 mg.dl-1 +/- SD) than the non-smokers (59.4 +/- 10.9) (P less than 0.0001) and a higher level of triglycerides (75.4 +/- 24.7 mg.dl-1) than the non-smokers (65.4 +/- 21.1 mg.dl-1). The smokers had a higher white cell count (8194 +/- 1981 vs 7332 +/- 1672 cells. 10mm-3) (P less than 0.001), a higher haemoglobin value (14.9 +/- 0.9 vs 14.6 +/- 0.9 g.dl-1) (P less than 0.004) and a higher haematocrit value (44.2 +/- 2.3 vs 43.6 +/- 2.7%) (P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

This paper evaluates the hematological indices in young smokers compared to non-smokers of similar age, diet, physical exercise, profession and alcohol consumption.
