(Abstract)
Objectives: The metabolic syndrome(MetS) is a major risk factor for coronary heart disease, type2 diabetes. This study was conducted to evaluate the related factors of metabolic syndrome(MetS) and its components of Korean for an specific age group(30-40 years old) by gender.
Methods: The findings of this study were based on the data from the Korea National Health and Nutrition Examination Survey (KNHANES) of 2014. Number of study population was 1,215 (male 508, female 707). The author adopted the MetS (metabolic syndrome) criteria from ‘2005 NCEP-ATP Ⅲ’, but the abdominal obesity was based on the criteria of ‘Korean Society for the Study of Obesity(KSSO). The study subjects were classified according to the number of MetS component as NG(normal group with0 Mets component), RG(risk group with1-2 Mets component) and MG(MetS group with3-5 Mets components). The multiple logistic regression analysis was performed to investigate related factors of mets and its component.
Results: The ratio of the three groups(NG,RG,MG) were respectively 24%, 50%, 26% in men and 50%, 41%, 9% in women. High triglycerides(TG) was major component regardless of gender, also low HDL-cholesterol accounted for equally high frequency in women. The related factors of high TG were ≥25㎏/㎡ body mass index[BMI: OR(odds ratio) 3.5, 95% CI(confidence interval) 2.3-5.5], white collar(OR 2.9, 95% CI 1.4-5.9), current smoker(OR 2.2, 95% CI 1.2-3.7) who smoked more than five packs of cigarettes life time in men, and for women ≥25㎏/㎡ BMI(OR 4.8, 95% CI 2.8-8.3), ≥9 sleeping hour(OR 2.6, 95% CI 1.1-6.3), family history(FH) with hyperlipemia(OR 2.9, 95% CI 1.3-6.5) and ≤3% saturated-fat intake(SatFI)(OR 2.8, 95% CI 1.4-5.5). Risk factors for the MetS were FH with diabetes mellitus(DM)(OR 2.8, 95% CI 1.2-6.3), ≤3% SatFI(OR 3.9, 95% CI 1.4- 11.0) or >6%(OR 2.6, 95% CI 1.1-6.1) in men, and for women ≤low-moderate income(OR 2.8, 95% CI 1.0-7.5), <college education level(OR 3.5, 95% CI 1.6-7.9), ≥9 sleeping hours(OR 4.4, 95% CI 1.4-13.5), ≥70% carbohydrate intake(CarbI)(OR 4.2, 95% CI 1.5-12.1), ≤3% SatFI(OR 3.1, 95% CI 1.3?7.6). Obesity(≥25㎏/㎡ BMI) was a major influential risk factor on all of the MetS components(p<0.001), also ≤3 or 6%<SatFI appeared as a multiple related factor on it(p<0.05).
Conclusions: The high BMI(≥25㎏/㎡) and SatFI(≤3 or 6%<) emerged as a major related factors on the MetS constituents between aged 30 and 49. Also, high TG was prevalent element, and the risk factors of high TG and MetS varied by gender. Obesity, sedentary lifestyle, smoking, FH with DM, and SatFI were associated with high TG in men, whereas low income and educational level, obesity, sleeping hour, FH with hyperlipemia, CarbI, and SatFI were related with high TG and low HDL cholesterol in women. So that, it is not only necessary to aware that the age and gender factors are important elements of MetS, but also necessary to conduct health education for prevention and management of MetS.
