Association of fatty acid composition in serum and / or adipose tissue lipids with lipid and carbohydrate metabolism in obese subjects of different age categories
Metelcová, Tereza ; Kunešová, Marie (advisor) ; Müllerová, Dana (referee) ; Štich, Vladimír (referee)
Obesity is a chronic disease that is caused by many factors. Excessive adipose tissue is involved in the development of metabolic and cardiovascular diseases. Prevention of cardiometabolic risks includes lifestyle arrangement, including an increased intake of omega 3 polyunsaturated fatty acids (PUFA). In additional to lifestyle factors, genetics factors also significantly contribute to influencing carbohydrate and lipid metabolism. In study A, we monitored 670 subjects (336 girls and 334 boys). Single-nucleotide polymorphisms (SNPs) in the FADS1 gene (rs174546, rs174537) was assessed using real-time PCR and then we determined the spectrum of fatty acids (FAs). The results show that SNPs in the FADS1 affect the efficiency of synthesis by affecting the activity of delta 5 desaturase. Abnormal FAs composition can affect cardiometabolic health. Study B examined a cohort of 215 individuals (131 women and 84 men) who participated in both rounds of the Childhood Obesity Prevalence And Treatment (COPAT) project. The individuals were divided into two groups: BMI≤25 kg/mš and BMI≥25 kg/mš. This model was evaluated regardless of sex because the variable sex did not correlate significantly with the variable weight status. The percentage of adipose tissue was used as the second parameter. The second parameter...
