Smoking duration and intensity on cholesterol levels in cigarette smokers and non smokers
Hypothesis one predicts that the level of cholesterol in the blood will be influenced by the intensity and duration of smoking. Table 1 shows that there is a significant increase in cholesterol levels depending on the intensity and duration of smoking. Compared to the non smokers, the levels of total cholesterol are significantly high in cigarette smokers. The mean value of total cholesterol in cigarette smokers is higher (P <0.001) compared to nonsmokers. Cholesterol levels are high in all groups of smokers (Mild, moderate, and heavy) but the risk of higher cholesterol is observed in heavy smokers.
