Background White matter hyperintensity (WMH) is a risk factor for dementia and ischemic stroke. The atherogenic index of plasma (AIP) is a simple and cost-effective marker for the prediction of various vascular diseases. In this study, we evaluated the relationship between AIP and WMH in adults without cerebrovascular accidents.
Methods We analyzed the data of 281 adults, aged ≥26 years, who underwent brain magnetic resonance imaging (MRI) at the health promotion center of an education hospital between January 2014 and December 2018. Participants were divided into three categories according to tertiles of the AIP scores (T1: <0.20; T2: 0.20–0.48; and T3: >0.48). WMH was defined as a modified Fazekas scale score of 1–3 on brain MRI. A cubic spline curve was used to determine the linearity of the relationship between AIP and WMH. Multiple logistic regression analysis was used to evaluate the relationship between the AIP and WMH.
Results The prevalence of WMH was 45.7% in T1, 57.0% in T2, and 66.0% in T3 (T3 vs. T1, P for post-hoc analysis=0.005). The increased odds of WMH were associated with increased AIP. The odds ratio (OR) with a 95% confidence interval (CI) for WMH of T2 and T3 compared with T1 were 1.57 (0.88–2.80) and 2.30 (1.28–4.14), respectively. After adjusting for confounding variables, the OR with a 95% CI for WMH in the T2 and T3 groups vs. the referent T1 were 1.55 (0.76–3.13) and 2.27 (1.06–4.84), respectively.
Conclusion AIP is independently and positively associated with WMH in a healthy population.

Background : Hypertension, diabetes, hyperlipidemia and coronary heart disease are closely related to obesity. Recently incidence of such diseases are remarkably increased. Many researches have been done to find out to implement prevention and treatment of such diseases. Abdominal obesity is one of the most important contributing factors of metabolic complication. This study was done to compare indicators of obesity with abdominal fat amount which was measured by anthropometric parameter and computed tomogram, and to find correlation between the risk factors of atherosclerosis and the indicators of obesity.
Methods : Fifty nine healthy premenopausal women without diabetes, coronary heart diseases or history of other chronic disease were enrolled. Blood pressure and simple anthropometric parameter were measured. Computed tomograms in umbilical and femoral regions were performed. From serial blood samples, plasma fasting glucose and insulin, cholesterol and triglyceride were measured and atherogenic index was calculated.
Results : The ratio of visceral fat area and skeletal muscle area at the mid-thigh level was found to be highly correlated(R=0.965, p<0.001) and atherogenic index showed similar patterns to the waist circumference, the waist/height ratio and the waist/hip ratio. Especially, the waist/height ratio was found to be the most reliable indicator of obesity to predict atherogenic index.
Conclusion : Although the ratio of visceral fat and skeletal muscle area at the mid-thigh level which is measured by computed tomogram was the best indicator of visceral fat, these results proved that waist circumference and the waist/height ratio were also good indicators of the risk factors of atherosclerosis. By simple anthropometric measurements, it can help to find the remedy and prevention of obesity in practices.
Background : Cigarette smoking is a major risk factor for cardiovascular disease and a correctable risk factor. In middle and old-aged men, cardiovascular disease is in prevalence than at any other age. Most smokes, start smoking in their twenties and continued to do of that in middle and old aged men, especially in young-and middle-aged men. We examined the association between smoking and their level of plasma lipids.
Methods : Subjects were 238 healthy male non-smokers and 238 male smoker of 21-45 years of age, age matched, and were comparatively observed from May 1 to November 30, 1997 in a university hospital, Taegu, Korea. Subjects were interviewed by a research doctor who recorded subject's sociodemographic data, drinking amount, exercise, smoking status and smoking amount. We checked the level of serum total cholesterol, HDL-cholesterol, triglyceride on a fasting state and BMI.
Results : The results showed that smoking had a remarkable influence on HDL cholecterol, triglyceride, atherogenic index(ratio of total cholesterol to HDL cholesterol) between HDL cholesterol of smoking group in 31-35 year age group were obviously lower than nonsmoking that age group. The level of triglyceride in 31-35, 41-45 year age group were obviously higher than same nonsmoking groups. Atherogenic index in 31-35 year age group was obviously higher than nonsmoking that age group. But, no association between cigarette smoking and level of plasma total cholesterol was observed. HDL cholesterol, triglyceride, atherogenic index were significantly different beyond 11 pack-years or 20 cigarettes/day smoking groups than nonsmoking groups.
Conclusion : Based on the these findings, it is recommend that smoking cessation strategies for perceived healthy third decade and fourth decade men build up. I suggest smoking cessation education should start in the early age as soon as possible.
