Correlation of Various Types of Cholestrol To Age and Gender in the Workforce of South Tangerang

Abstract

The internship within the Biomedilab Bumi Serpong Damai (BSD) organization assigned the student to laboratory quality control-focused tasks. Quality control regarding the analytical process is required to ensure accuracy regarding the patient’s data. Mismeasurement of the analytes could result in severe consequences due to misdiagnosing the condition of the patient. Analytical tools included chemical analysis, hematology and urinalysis. Chemical analysis aims to measure specific substances in the body, such as: proteins, fats and glucose, which allows evaluation of organ functions. Hematology measures the composition of blood cells which helps monitor blood conditions, such as: leukemia, bleeding and anemia. Urinalysis assesses urine contents to identify health issues relating to the function of the liver and kidney function. The project revolves around the lipid profile, which consists of Total Cholesterol, High Density Lipoprotein (HDL), Low Density Lipoprotein (LDL), and Triglycerides (TG), of workers in South Tangerang obtained through chemical analysis. Due to the high fat and sugar content in Indonesian cuisine, especially in street food and snacks, cholesterol has been a constant concern in Indonesia. The project aims to investigate the correlation between gender and age towards the lipid profile of adult workers and correlation between each variable of the lipid profile. ANOVA (analysis of variance) was used in the first analysis and shows age affecting all 4 variables while gender affects HDL and TG levels. Correlation matrix was used to investigate interactions between each variable and found total cholesterol positively correlates to the other variables whilst HDL has a negative correlation with TG and LDL seemingly unaffected by TG and HDL levels.
