On the other hand, physical inactivity and bad nutritional habits had multiple bad health impacts. The aim of this study was to examine the effect of physical activity, physical inactivity and nutritional habits on the lipid profile and Atherogenic Index of Plasma (AIP). In this cross sectional study, a sample of 207 healthy medical students (100 males and 107 females) were recruited. Lipid profile measured by spectrophotometer. Arab Teens Lifestyle (ATLS) questionnaire was used for assessment of physical activity status and dietary habits. The results revealed that Low Density Lipoprotein (LDL) was significantly higher in males than females. Triglyceride (TG) was significantly negatively correlated with the frequency of stair climbing. TG was significant positively correlated with sleeping hours. High TG was associated with increase fruits intake. Total Cholesterol (TC) was significantly negatively correlated with the time spending in dancing in female. atherogenic index of plasma was significantly higher in males and significantly higher in inactive participants. Based on the results, it is concluded that moderate intensity physical activity decrease the total cholesterol and triglyceride while increase sleeping hours increase triglyceride. Therefore, increasing the physical activity intensity and decreasing physical inactivity time should be used as preventive measure for cardiovascular diseases.
