CHOLESTEROL AND TRIGLYCERIDE STATISTIC AND STUDY
The purpose of the topic was to do a statistical analysis of both levels of cholesterol and triglyceride for a sample chosen from people living in Damascus as a screening test. Aiming to identify the average levels of both cholesterol and triglyceride and find out the percentage of any elevation in those levels over the boarder line. Then the study pland to compare the Values between males and females, in our community and with other values from other world communities. The study aimed by a statistical manner to analyze the possibility of having one test, whether cholesterol or triglyceride to be able to replace the other. Additionally, the study aimed to find out an existence of any correlation between the cholesterol and triglyceride concentration in the same individuals in our sample.
The total number of the individuals who had cholesterol-screening test was 290, 139 females and 151 males, and for the triglycride, it was as a total of 270, 124 females and 146 males, chosen from people attending the lab for general checkup between Jan- 2004 and Aug-2005.
· _ Both the average and standard deviation were taken for cholesterol and triglyceride in all the categories males, females and both and included in a table.
_ The percentage of individuals who had elevated level of cholesterol or triglyceride was calculated,
_ And I designed a study on 180 individual from both sex whom I did both cholesterol and triglyceride tests on them from the same sample, to find out, whether one of both tests is capable to replace the other, and I used the (F- test) and then (the student T- test) on both sexes to gather and on each sex separately.
_ Then it was decided to find out the existence of any kind of correlation between cholesterol and triglyceride levels in each individual of the 180 screened.
The results were as follows: The percentage of elevated cholesterol > 200 mg/dl including both males and females sample together, was %56 and the average cholesterol level was 206.5 mg/dl, while the percentage of elevated triglyceride level > 150mg/dl was %47 and the average triglyceride level was 160.1 mg/dl. The t-student test showed in 180 individual from both sex, the value 4.62 and the correlation was 0.276 . While it showed the value of 0.63 on the female alone sample.
The purpose of the study was to evaluate and compare the cholesterol and triglyceride levels in a statistical manner on a sample chosen from Syria, with other samples from different parts of the world in order to identify any elevation in both cholesterol and triglyceride level in our sample (which indeed, was found), aiming to draw attention of the community to the importance of establishing a program in Syria that consider reducing the cholesterol and triglyceride levels for better health. Further more, the study found that the cholesterol or the triglyceride tests are independent of each other which means that one test will not be sufficient in any way to express the other test significance. Additionally, the statistical analysis found that a correlation exists between the cholesterol, triglyceride increase / decrees levels on our female samples but not in our males.
