説明

Background We examined the association between WBC count and lifestyle factors, and the effects of habitual exercise on WBC count.<br>Methods We conducted a questionnaire survey on 112 subjects undergoing a complete medical check-up at our hospital using computer-graded answer sheets to determine whether or not they (1) are currently suffering from mental stress; (2) smoke 20 or more cigarettes each day and; (3) exercise at least once a week. We also measured BMI to investigate the association between these factors and the WBC count. Furthermore, we analyzed abnormal WBC counts using logistic regression.<br>Results WBC count significantly increased in the subjects who were current smokers and those with a BMI≧25 kg/m2. Among the subjects who exercised regularly, we observed a significant decrease in WBC count of those with mental stress, and a predisposition towards decreased WBC count in those who were currently smokers; however, there was no significant difference in BMI. Moreover, current smoker status was an independent risk factor for abnormal WBC count.<br>Conclusion WBC count increased in the current smokers and overweight subjects with a BMI of 25 kg/m2 or above. The results, however, suggest that although habitual exercise at least once a week can prevent an increase in WBC count caused by smoking, it does not have any effect on the increase in WBC count caused by being overweight.
