Abstract:
Several studies have reported an association between dietary fat quality and
risk of coronary heart disease, therefore the purpose of this study was to determine and
examine the profile of serum total fatty acids concentration of n-3, n-6 and trans fatty
acids between healthy control and subjects with various diseases. A cross-sectional
study was performed to investigate 222 subjects from CEGAT study. They were
divided into 38 apparently healthy groups, 11 subjects with hypertension, 25 subjects
with hypercholesterol, 38 subjects with diabetes mellitus and hypertension and
dyslipidemia, 78 subjects with hypertension and dyslipidemia and 37 subjects with
coronary heart disease. Blood collection, lifestyle assessment, nutrition assessment and
dietary assessment were investigated. Blood samples were assessed to serum lipid and
serum fatty acids concentration and compare the serum lipid and serum fatty acids
concentration between healthy control and subjects with various diseases.
Between healthy control and subjects with coronary heart disease, the
clupadonic acuid (22:5, n-3) and DHA (22:6, n-3) in healthy control were significantly
higher than subjects with coronary heart disease. The ALA (18:3, n-3) in subjects with
hypertension was significantly higher than healthy control. The LA (18:2, n-6) in
subjects with hypercholestserol was significantly higher than healthy control but the
AA (20:5. n-3) was significantly lower than healthy control. Triglyceride in healthy
control was significantly lower than subjects with diabetes mellitus and hypertension
and dyslipidemia and subjects with hypertension and dyslipidemia. Cholesterol, HDLC
and LDL-C in subjects with hypercholerterol were significantly higher than healthy
control. Lifestyle and dietary assessment were investigated from questionnaires and
the results show that frequency of exercise influenced the level of serum HDL-C in
subjects with CHD. Smoking status affected BMI in healthy controls and subjects with
CHD. Alcohol intake affected BMI and WHR in subjects with HC.
