不同糖代谢状态人群的肥胖指标与动脉硬化的相关性

目的研究北京市社区不同糖代谢状态人群的肥胖指标与动脉硬化的相关性。方法用臂-踝脉搏波传导速度(baPWV)反映动脉硬化程度。对北京市石景山区两个社区大于或等于40岁居民进行体格检查,测量体重(weight)、腰围(WC)、体重指数(BMI)、腰臀比(WHR)、腰围升高比(WHtR)及标准化问卷调查、生化和糖化血红蛋白检测、75 g葡萄糖耐量实验及baPWV测量。对数据资料完整及BMI大于或等于18.5 kg/m2的9 080名人员根据75OGTT试验及糖尿病史分为NGT、IGR和DM组,分析BMI、WC、WHR、WHtR与baPWV之间的关系。结果在NGT、IGR、DM组,根据WC、WHR、WHtR分成亚组,中心型肥胖组的baPWV明显高于正常组(P0.01),在DM组内,以BMI作为肥胖标准,baPWV仅在NGT和IGR组内有统计学意义,在DM组无显著差异(P0.05)。在NGT、IGR和DM组内,中心型肥胖指标(WC、WHR、WHtR)与baPWV呈显著正相关(P0.05),BMI仅在NGT组内与baPWV呈正相关,在IGR和DM组内无明显相关(P0.05)。校正年龄、性别、心血管危险因素,通过多元回归分析发现,WHR和WHtR每增加0.1,baPWV则随之升高40.6 cm/s和55.3 cm/s。结论在糖代谢异常人群中,中心性肥胖指标(WC、WHR、WHtR)与动脉硬化呈正相关,较BMI更能反映动脉硬化程度。

2型糖尿病患者中NT-proBNP与动脉粥样硬化的相关性研究

了解入选门诊2型糖尿病患者160例,log(NT-proBNP)与脉搏波呈正相关,与臂踝指数呈负相关。多因素回归分析,可见年龄、收缩压、总胆固醇、尿酸、吸烟情况、log(NT-proBNP)与脉搏波独立相关,收缩压、log(甘油三酯)、log(NT-proBNP)与臂踝指数独立相关。因此,NT-proBNP可以作为2型糖尿病患者动脉粥样硬化的标志。

Triglyceride and lipoprotein (a) are markers of coronary artery disease severity among postmenopausal women

Objective: After menopause, some women manifest coronary artery disease (CAD) with highly variable angiographic severity. For these women, postmenopausal appearing of some CAD risk factors may have differently influenced the CAD risk and severity. In this study, we attempt to unravel differences in the frequency or intensity of CAD risk factors among postmenopausal women with different angiographic severity. Methods: We studied 182 postmenopausal women (64±6 years) who underwent coronary angiography to investigate thoracic pain. Subjects with no detectable coronary lesions at angiography were recruited to the non-obstructive group and patients with CAD were grouped in one-vessel or multi-vessel groups. We compared clinical variables as the body mass index (BMI), age at menopause, age, hypertension, diabetes and cigarette smoking, and lipid measurements as plasma levels of total cholesterol, triglyceride, low-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, apolipoprotein (apo) A1, apo B and lipoprotein(a) (Lp(a)). Results: Comparing to the non-obstructive group, Lp(a) was twofold higher in the one-vessel group and threefold higher in the multi-vessel group and triglycerides were 34% higher in the one-vessel group and 50% higher in the multi-vessel group. No further difference was found among the three groups. After multivariate logistic regression analysis, triglyceride (odds ratio: 1.01; P=0.0013) and Lp(a) (odds ratio: 1.006; P<0.0001) were independently indicative of the presence of obstructive CAD. Conclusion: We found that both Lp(a) and triglycerides constitute useful markers of CAD severity among postmenopausal women.     

Lipoprotein (a), low-density,intermediate-density lipoprotein,and blood pressure in a young male population

Summary Both hypercholesterolemia and hypertension are risk factors for atherosclerotic vascular disease, and elevated cholesterol levels occur more frequently than expected in patients with hypertension. Elevated levels of intermediate-density lipoproteins (IDL) and low-density lipoproteins (LDL) were shown to be atherogenic, and LDL, comprising the major cholesterol-carrying fraction in human plasma, are structurally related to lipoprotein (a) [Lp(a)], a further risk factor for atherosclerosis. In the present study we investigated 200 male employees (mean age 26±7 years) to determine whether the relationship of IDL and Lp(a) to systemic blood pressure is similar to the reported correlations between total and LDL cholesterol and systemic blood pressure. To this end blood pressure was measured several times in each individual, and lipids, lipoprotein-cholesterol, apolipoprotein B (apo B), and Lp(a) were determined in fasting serum. IDL cholesterol and apo B, the main protein component of IDL and LDL correlated with blood pressure. However, levels of Lp(a) correlated neither with systolic or diastolic blood pressure nor with lipoprotein cholesterol, body weight, or age. Although IDL and Lp(a) are considered lipoprotein risk factors for atherosclerosis, levels of Lp(a), unlike IDL, are not related to blood pressure, body weight, or age. Our data suggest different metabolic and pathophysiological mechanisms of the risk factors, IDL, LDL, and Lp(a).Abbreviations VLDL very low density lipoprotein - IDL intermediate-density lipoprotein - LDL low-density lipoprotein - ApoB Apolipoprotein B - Lp(a) lipoprotein (a) - BMI body mass index Dedicated to Prof. Dr. N.

The association between sleep duration, body mass index and metabolic measures in the Hordaland Health Study

Several studies show that short self-reported sleep duration is associated with elevated body mass index (BMI). Short sleep duration may change appetite hormones, but whether this also influences metabolic measures like cholesterol and triglycerides is less clear. Furthermore, obesity is linked to increases in blood pressure, and recently, short sleep duration has been shown to be an independent risk factor for hypertension. This is a population-based cross-sectional study (The Hordaland Health Study). A subgroup of 8860 subjects, aged 40-45 years, answered a sleep questionnaire. Body weight, height and blood pressure were measured, and non-fasting blood samples were collected and analyzed for total cholesterol, HDL-cholesterol and triglycerides. Sleep duration was divided into the following subgroups: < 5, 5-5.99, 6-6.99, 7-7.99, 8-8.99 and > or = 9 h. The results show that short sleep duration was associated with elevated BMI and increased prevalence of obesity. Similar to BMI, levels of cholesterol, triglycerides, systolic and diastolic blood pressure were higher in subjects with short sleep duration. This co-variation seemed to be attributed to variables like gender, smoking and BMI. In conclusion, our study confirms a clear association between short sleep duration and elevated BMI and obesity. Furthermore, levels of total cholesterol, HDL-cholesterol, triglycerides and blood pressure were associated with sleep duration.     

Lipid and lipoprotein measurements in a normal, adult Cuban population

An attempt was made to determine the normal reference values of lipid- and lipoprotein levels (cholesterol), triglycerides, cholesterol in high- and low-density lipoproteins) in a selected, apparently healthy, Cuban population. Results were expressed as mean, and various percentiles of measured values; two ratios: Risk 1 (LDL-C/HDL-C) and Risk 2 (TC/HDL-C) were also calculated. Approximately 40% of the subjects aged 20 to 30 years had cholesterol values above 200 mg/dl. Females had significantly higher cholesterol HDL-C values than males, whereas the concentrations of LDL-C and LDL were higher in males. Risk 2 ratios were elevated in males. A correlation was shown between lipid levels and age. There was a strong negative correlation between HDL-C and relative body weight. It is suggested that obesity might be an individual risk factor in the population studied.

U-curved relation between total fasting serum cholesterol and hostility: A population-based study

Some researchers have found higher cholesterol levels linearly related to hostility, whereas others have found no relation. Even so, it remains unclear whether research should seek to find a linear relation between hostility and cholesterol levels. We hypothesized that a U-curved association was the proper test of the relation between hostility and cholesterol. Total fasting and low-density lipoprotein (LDL) cholesterol levels were collected from a population-based sample of 2,306 Canadians. Barefoot’s (1989) scoring of the Cook-Medley Hostility Scale was used to assess hostility levels. Both a linear and a U-curved relation among hostility scores, fasting total, and LDL cholesterol levels were significant. Participants with low and high cholesterol levels had significantly higher hostility scores than the normal cholesterol group. A U-curved relation between hostility and serum cholesterol levels may be a more appropriate function to consider given the all-cause mortality findings we seek to explain.
