Comparison of Low Density Lipoprotein Cholesterol Level in Second and Third Trimester of Pregnancy in Mymensingh Region of Bangladesh.

: Altered metabolic and hormonal status of the body in pregnancy leads to changes in lipid profile. High Lipid profile, a major factor behind atherosclerosis may leads to unconsciousness. To avoid such problems during pregnancy this longitudinal study was carried out in the Department of Biochemistry, Mymensingh Medical College in co-operation with the Department of Obstetrics and Gynaecology, Mymensingh Medical College Hospital and Community Based Medical College Hospital, Bangladesh during the period from July 2011 to December 2012 to compare the changes in low density lipoprotein cholesterol level during 2nd and 3rd trimester of pregnancy. A total of one hundred subjects were participated in this study comprising of second and third trimester of pregnancy. All subjects were made to fast overnight at least for a minimum of 8 hrs. Blood samples were taken and analyzed by enzymatic colorimetric kit method. Pregnancy has being found to be associated with changes in lipid profile and this differs with each trimester. The average results were analyzed with respect to each pregnancy for the whole group. The study proves that serum Low Density Lipoprotein (LDL) cholesterol increases in third trimester (174.83±13.78 mg/dl) than second trimester (156.77±7.96 mg/dl) of pregnancy. Therefore, lipid profile estimation and monitoring should be made as a part of routine investigation during antenatal period.
