Blood Diseases in Cyprus and the Effect of Predisposing Factors of Tobacco and Air Pollution

Abstract

Aim: The aim of this work is to study the diseases of the human blood in Cyprus and their relationship to smoking and air pollution. Methods: The statistical methods were used to derive the results of this work are Student t-test in order to check the statistical significance of blood diseases in relation to gender, One-Way ANOVA test in order to check the statistical significance of human blood diseases in relation to age and the Pearson correlation coefficient for the relationship between the diseases of blood and both predisposing factors of smoking and air pollution. Results: The results showed that there is statistically significant difference in the number of blood diseases in relation to gender, and more specifically, Leukaemia occurs more often in men. There is a statistically significant relationship between blood diseases and age, and in particular they occur mainly at ages 65 and over. Exceptions are certain disorders involving the immune mechanism, which occur most often in ages 15-44. Finally, there is a statistically significant relationship between the numbers of incidents of blood diseases with air pollution and there is no statistically significant relationship with smoking. Conclusions: This work has shown that diseases of the blood vary with gender and age, while air pollution is an important predisposing factor. Moreover, from all blood diseases, most deaths in both genders are observed in Leukemia.
