Cardiovascular disease risk factors in males with normal body weight and high waist-to-hip ratio.

BACKGROUND: Overweight and the distribution of body fat are both associated with the development of cardiovascular diseases (CVD). The relation of abdominal body fat distribution to CVD may depend on the degree of obesity. OBJECTIVE: The purpose of the present study was to evaluate the cardiovascular disease risk factor levels in males with high waist-to-hip ratio (WHR) in the absence of overweight. DESIGN: Cross-sectional study of 231 male subjects (21-69 years old). METHODS: Anthropometric measurements (height, weight, BMI, fat%, skinfolds, waist circumference, WHR), systolic and diastolic blood pressure (BPsyst, BPdiast), serum lipids and lipoproteins (CHOL, HDL-C, LDL-C, TG), glucose (GL), and physical working capacity. A questionnaire was drawn up to evaluate physical activity level and lifestyle patterns. RESULTS: Subjects with WHR > or = 0.9, BMI < 27.0 and with WHR > or = 0.9, BMI > or = 27.0 showed statistically significant differences in all measured anthropometric and blood pressure values in comparison with the control group (WHR < 0.9, BMI < 27.0). Compared with the controls, subjects with WHR > or = 0.9, BMI > or = 27.0 had significantly higher risk (OR) for hypertension and elevated LDL-C. Physical activity was a significant determinant of the high WHR. CONCLUSIONS: WHR has independent associations with some CVD risk factors, but the effect increases with weight.

The relationship between waist circumference and metabolic risk factors: cohorts of European and Chinese descent

Waist circumference (WC) may be the best anthropometric index for identifying individuals at risk for cardiovascular disease (CVD) and diabetes mellitus (DM). The objectives of this study were to determine if the relationship between WC and metabolic risk factors is similar in men and women of Chinese and European descent, and to assess the effect of ethnicity on these relationships. Apparently healthy men and women of Chinese (n = 92) and European (n = 99) descent were recruited from hospital staff and assessed for anthropometric variables and blood pressure (BP), lipids, insulin, and glucose. The study cohort was stratified by sex, and regression analyses were performed with the various metabolic risk factors as the outcome and WC and ethnicity as predictors. Chinese men and women had significantly lower WC than European men and women. Age and metabolic risk factors were similar between the 2 ethnic groups except for BP. Metabolic risk factors significantly correlated with WC within each gender and ethnic cohort. In men, ethnicity was an independent predictor for total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), and the ratio of TC to high-density lipoprotein cholesterol (HDL-C) after controlling for WC. In women, ethnicity significantly interacted with WC as an independent predictor of TG, TC:HDL-C ratio, insulin, and glucose. As ethnic descent modifies the relationship between WC and metabolic risk factors, current WC targets derived from relationships in European populations are not applicable to Chinese men and women. Therefore, ethnic background should be considered when using WC as a marker of cardiovascular risk.     

男性体脂肪含量及其分布与血脂关系的研究

目的探讨男性体脂肪含量及脂肪分布与血脂代谢的关系。方法采用临床横断面研究,对194例青岛港男职工行体脂肪测定仪检查和血脂的测定,将所有入选对象分为血脂异常组和血脂正常组,两组之间比较。结果两组间脂肪量和肥胖度差异没有统计学意义(P>0.05);血脂异常组脂肪率、腹部总脂肪面积、腰围(WC)、腰臀比(WHR)和体重高于对照组(P<0.05);脂肪量和肥胖度与甘油三酯(TG)成正相关;腹部总脂肪面积、WC和WHR均与总胆固醇(TC)、低密度脂蛋白-胆固醇(LDL-C)和TG成正相关,与高密度脂蛋白-胆固醇(HDL-C)成负相关;脂肪率与TC、LDL-C成正相关,与HDL-C成负相关。结论男性脂肪量、尤其是脂肪分布与血脂代谢有关,腹部总脂肪面积是预测心血管危险因素的一个指标。     

Modification of the relationship between simple anthropometric indices and risk factors by ethnic background

Current targets for body mass index (BMI) and waist circumference (WC) may not be appropriate for those of South Asian origin. The objectives of this study were to determine whether the relationship between BMI and WC with risk factors for cardiovascular disease (CVD) is the same for men and women of South Asian and European descent. Apparently healthy men and women of European (n = 88) and South Asian (n = 93) descent were recruited from 3 hospital communities and assessed for BMI, WC, waist-to-hip ratio (WHR), blood pressure (BP), lipids, insulin, glucose, and CRP. The study cohort was stratified by sex, and regression analyses were performed with individual risk factors as outcomes and ethnicity with either BMI or WC as predictors adjusting for age and height (WC only). BMI and WC were similar between the European and South Asian men and women. South Asian men had significantly higher values for total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), triglycerides (TG), total cholesterol:high-density lipoprotein-cholesterol (HDL-C) and CRP, and significantly lower values of HDL-C. South Asian women had significantly higher values for TG, TC:HDL-C and CRP and significantly lower values of HDL-C, glucose, systolic BP and diastolic BP. In men, ethnicity was an independent predictor for all risk factors except for glucose and insulin, after adjusting for either BMI or WC independent of age and height. For women, ethnicity was an independent predictor for all risk factors except for total cholesterol (WC model only) and insulin (BMI model only), after adjusting for either BMI or WC independent of age and height. The relationship between BMI or WC and risk factors is such that men and women of South Asian descent present with a more adverse risk profile than those of European descent at the same BMI and/or WC.

Associations between serum lipids and causes of mortality in a cohort of 3,499 urban Thais: The Electricity Generating Authority of Thailand (EGAT) study

The association between serum lipids and mortality has not previously been established in Thailand. Baseline data from the Electricity Generating Authority of Thailand (EGAT) cohort study, plus a resurvey of the cohort 15 years later were analyzed. Participants were employees of EGAT: 2,702 men and 797 women. Total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), and triglycerides (TG) were taken as predictive variables; age, sex, hypertension, diabetes, cigarette smoking, alcohol drinking, and body mass index were taken as confounders. Dependent variables were all-causes and specific causes of mortality over 17 years of follow-up. The major cause of death among men was cardiovascular disease (CVD); among women, it was cancer. Relative risks (RR) for specific causes of death, for a mmol/L increase in each lipid, were estimated after adjustment for confounding factors using Cox proportional hazards regression. TC and LDL-C were negatively associated with liver cirrhosis mortality, although it was likely that the low cholesterol concentration was a consequence of the disease. HDL-C was negatively associated with CVD mortality (RR = 0.59; 95% confidence interval [CI], 0.39-0.93), coronary heart disease (CHD) mortality (RR = 0.36; 95% CI, 0.17-0.75) and all cause-mortality (RR = 0.68; 95% CI, 0.54-0.87). TG was not associated with mortality. HDL-C is an important risk factor for CVD in middle-class urban Thais. Health promotion programs to improve lipid profiles, such as effective exercise campaigns and dietary advice, are required to increase HDL-C and to help prevent CVD and premature death in Thailand.     

Suboptimal lipid levels in clinical practice among Portuguese adults with dyslipidemia under lipid-lowering therapy: Data from the DISGEN-LIPID study

IntroductionCardiovascular disease (CVD) is the leading cause of morbidity and mortality in Portugal. Hypercholesterolemia has a causal role in atherosclerotic CVD. Guidelines recommend that cardiovascular (CV) risk reduction should be individualized and treatment goals identified. Low-density lipoprotein cholesterol (LDL-C) is the primary treatment target.MethodsDISGEN-LIPID was a cross-sectional observational study conducted in 24 centers in Portugal in dyslipidemic patients aged ≥40 years, on lipid-lowering therapy (LLT) for at least three months and with an available lipid profile in the previous six months.ResultsA total of 368 patients were analyzed: 48.9% men and 51.1% women (93.9% postmenopausal), of whom 73% had a SCORE of high or very high CV risk. One quarter had a family history of premature CVD; 31% had diabetes; 26% coronary heart disease; 9.5% cerebrovascular disease; and 4.1% peripheral arterial disease. Mean baseline lipid values were total cholesterol (TC) 189 mg/dl, LDL-C 116 mg/dl, high-density lipoprotein cholesterol (HDL-C) 53.5 mg/dl, and triglycerides (TG) 135 mg/dl. Women had higher TC (p<0.001), LDL-C (non-significant) and HDL-C (p<0.001), and lower TG (p=0.002); 57% of men and 63% of women had LDL-C>100 mg/dl (p=0.28), and 58% of men and 47% of women had LDL-C>70 mg/dl (p=0.933).ConclusionThese observational data show that, despite their high-risk profile, more than half of patients under LLT, both men and women, did not achieve the recommended target levels for LDL-C, and a large proportion also had abnormal HDL-C and/or TG. This is a renewed opportunity to improve clinical practice in CV prevention.     

心血管高危患者踝臂指数与血尿酸水平的相关性分析

目的探讨心血管高危患者踝臂指数与血尿酸水平的相关性。方法选取高血压和(或)糖尿病患者363例,将单纯原发性高血压189例作为高血压组、原发性高血压合并2型糖尿病123例作为合并组和单纯2型糖尿病51例作为糖尿病组,均常规治疗,检测患者踝臂指数(ABI)、血尿酸和其他心血管疾病危险因素,并应用偏相关分析血尿酸、ABI与其他临床指标相关性。结果 3组收缩压、舒张压、TG、HDL-C、糖化血红蛋白(HbA1c)比较,差异有统计学意义(P<0.05)。高血压组和糖尿病组ABI高于合并组(1.12±0.09和1.11±0.07 vs 0.93±0.11,P=0.012)。校正高血压、糖尿病病史、年龄、性别、体质量指数、TG、TC、HDL-C、LDL-C、HbA1c、收缩压、舒张压等的影响因素后,ABI与血尿酸呈负相关(r=-0.235,P=0.012)。结论心血管高危患者的ABI与血尿酸可能存在相关性。     

Prevalence and significance of cardiovascular risk factors in a large cohort of patients with familial hypercholesterolaemia

OBJECTIVE: Patients with familial hypercholesterolaemia (FH) vary widely in terms of onset of cardiovascular disease (CVD). DESIGN: The association between cardiovascular risk factors and prevalent CVD was examined in a cross-sectional study in order to elucidate their contribution to atherogenesis. SETTING AND SUBJECTS: Patients were recruited from 37 Dutch Lipid Clinics. The diagnosis of FH was based on a uniform diagnostic protocol, confirmed by DNA analysis in 62% of the cases. All patients were investigated free from any lipid-lowering drug for at least 6 weeks. MAIN OUTCOME MEASURES: Differences in lipids, lipoproteins and other risk factors for CVD were analysed in FH patients with and without CVD. RESULTS: A total of 526 patients were assessed and more than 37% had a history of CVD with a mean age of onset of 46.8 years. Mean LDL cholesterol (LDL-C) levels were severely elevated (8.38 +/- 2.13 mmol L-1). In univariate analysis, age, presence of hypertension or diabetes, body mass index, triglycerides (TG) and low HDL cholesterol (HDL-C) were all significantly associated with CVD. Also in multivariate analysis, all these risk factors, except TG and diabetes, were significantly linked to CVD. CONCLUSION: A high CVD risk in this large well-documented characterized sample of FH patients is not only conferred by elevated LDL-C but also by low HDL-C.     

Adiponectin is independently associated with apolipoprotein B to A-1 ratio in Koreans

Apolipoprotein B to A-1 (apo B/A-1) ratio is reportedly a better predictor of atherosclerotic vascular disease than low-density lipoprotein cholesterol (LDL-C). The aim of this study was to assess the association of serum apo B/A-1 ratio with insulin resistance and adiponectin in patients with different grades of glucose intolerance. Patients were divided according to glucose tolerance into 3 groups: normal glucose tolerance without metabolic syndrome (n = 229), impaired fasting glucose (subjects with fasting plasma glucose level between 100 and 125 mg/dL, n = 658), and type 2 diabetes mellitus (n = 381). Serum concentrations of apo B, apo A-1, glucose, total cholesterol (TC), triglycerides, and high-density lipoprotein cholesterol (HDL-C) and adiponectin were measured. Insulin resistance was estimated by the homeostasis model assessment of insulin resistance index (HOMA-IR). There were significant differences in metabolic parameters among the groups, including waist circumference, insulin, HOMA-IR, and apo B/A-1 ratio, which increased sequentially with glucose intolerance, whereas adiponectin level decreased with increasing severity of glucose intolerance. The apo B/A-1 ratio was significantly correlated with TC, triglycerides, LDL-C, HDL-C, adiponectin, and HOMA-IR in normal glucose tolerance, impaired fasting glucose, and type 2 diabetes mellitus. Multiple regression analysis showed that apo B/A-1 ratio was significantly associated with TC, LDL-C, HDL-C, and adiponectin. In conclusion, apo B/A-1 ratio was significantly associated with insulin resistance according to glucose intolerance; and serum adiponectin was an important independent factor associated with apo B/A-1 ratio in Koreans.     

Lipids, lipoproteins, lifestyle, adiposity and fat-free mass during middle age: the Fels Longitudinal Study

INTRODUCTION: Although lipid profiles tend to worsen with age, it is not fully known if such age-related changes are influenced primarily by body composition and lifestyle or by other aspects of aging. OBJECTIVE: We investigated the extent to which the fat and fat-free components of body mass index (BMI) and lifestyle factors influence patterns of change in lipids independent of age. DESIGN: Serial data were analyzed using sex-specific longitudinal models. These models use serial data from individuals to assume a general pattern of change over time, while allowing baseline age and the rate of change to vary among individuals. SUBJECTS: Serial data were obtained from 940 examinations of 269 healthy white participants (126 men, 143 women), aged 40-60 years, in the Fels Longitudinal Study. MEASUREMENTS: Measurements included age, the fat (FMI) and fat-free mass (FFMI) components of BMI, high-density lipoprotein (HDL-C), low-density lipoprotein (LDL-C), triglycerides (TG), total cholesterol (TC), fasting glucose and insulin, physical activity, alcohol use and smoking, and women's menopausal status and estrogen use. RESULTS: In both sexes, increased FMI was significantly associated with increased LDL-C, TG and TC, and decreased HDL-C. Increased FFMI was significantly related to decreased HDL-C and increased TG. Independent age effects remained significant only for LDL-C and TC in men and TC in women. Increased insulin was significantly related to increased TG in women. Moderate alcohol consumption was associated with higher HDL-C in men. Physical activity lowered male LDL-C and TC levels, and increased female HDL-C levels. Menopause was associated with increases in LDL-C. Premenopausal women not using estrogen had significantly lower HDL-C, TG, and TC than postmenopausal women taking estrogen. CONCLUSIONS: (1) Age is an important independent predictor for LDL-C and TC in men, and TC in women, but it is not as influential as body composition and lifestyle on HDL-C and TG in men and women, and LDL-C in women. (2) Increasing FMI is the major contributor to elevated TC, LDL-C and TG levels, and decreased HDL-C levels in men and women. (3) FFMI significantly influences HDL and TG levels in both sexes. (4) Maintaining a lower BMI via a reduced fat component may be more beneficial in lowering CVD risks than other factors.

Triglyceride/HDL-cholesterol ratio is an independent predictor for coronary heart disease in a population of Iranian men

Background and aimsTo determine whether triglyceride/high-density lipoprotein cholesterol ratio (TG/HDL-C), which has been shown to be an indicator of the metabolic syndrome (MetS) and insulin resistance, can predict coronary heart disease (CHD) independently of total cholesterol (TC) and other risk factors in an Iranian population with a high prevalence of MetS and low HDL-C.Methods and resultsBetween February 1999 and August 2001, 1824 men ≥40 years old, free of clinical cardiovascular diseases at baseline, were followed. Baseline measurements included serum level of TC, HDL-C, TG and risk factors for CHD including age, systolic and diastolic blood pressure, body mass index, waist circumference, diabetes, smoking and a family history of premature cardiovascular diseases. During a median follow up of 6.5 years until March 2007 (11,316 person-years at risk), a total of 163 new CHD events (27 fatal and 136 nonfatal) occurred. The prevalence of MetS in subjects with TG/HDL-C ≥6.9 (top quartile) reached 63.6% versus 3.0% in those with TG/HDL-C <2.8 (low quartile). According to a stepwise Cox proportional hazard model, including TG and TG/HDL-C quartiles, with TC and other risk factors, men in the top quartile of TG/HDL-C relative to the first quartile had a significant hazard ratio (HR) of 1.75 (95% CI, 1.02–3.00), while TG did not remain in the model.ConclusionThe evaluation of TG/HDL-C ratio should be considered for CHD risk prediction in our male population with a high prevalence of MetS.     

代谢综合征患者C-反应蛋白与心血管病危险因素关系

目的 了解代谢综合征病人C反应蛋白与心血管病危险因素之间的关系.方法 回顾分析代谢综合征175例,根据C反应蛋白水平分为高C反应蛋白组和正常C反应蛋白组.检测两组体质量指数、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇、总胆固醇、甘油三酯、空腹血糖、餐后2小时血糖、糖化血红蛋白、收缩压和舒张压.结果 高C反应蛋白组的体质量指数、低密度脂蛋白胆固醇、总胆固醇、甘油三酯、空腹血糖、餐后2小时血糖、糖化血红蛋白、收缩压、舒张压均显著高于正常C反应蛋白组,而高密度脂蛋白胆固醇水平显著低于后者（P＜0.01）;C反应蛋白水平与体质量指数、甘油三酯、低密度脂蛋白胆固醇、糖化血红蛋白、舒张压、空腹血糖及餐后2小时血糖水平呈正相关（P＜0.05）,与高密度脂蛋白胆固醇呈负相关（P＜0.05）.结论 代谢综合征病人中C反应蛋白升高者往往伴随多种代谢紊乱加重,心血管病的危险因素亦随之加重,故对此类病人更要加强防治措施.     

Sintomas Depressivos estão Associados a Níveis Séricos Elevados de Colesterol de Lipoproteína de Baixa Densidade em Idosos com Diabetes Mellitus Tipo 2

Background Type 2 Diabetes Mellitus (T2DM) is common in older adults, who also present a high level of risk factors for cardiovascular disease (CVD), such as dyslipidemia. However, the role of depression in T2DM patients and its relationship with CVD risk factors are understudied.Objective The present study aimed to investigate the relationship between depressive symptoms (DS) and known cardiovascular risk factors in community dwelling older adults with T2DM.Methods This is a cross sectional study, in which 85 community-dwelling older adults with T2DM were assessed. DS was assessed using the Yesavage Geriatric Depression Scale - short version (GDS-15). The following cardiovascular risk factors were evaluated: systolic (SBP) and diastolic blood pressure (DBP), fasting plasma glucose (FPG), lipid profile (serum triglycerides - TG, serum total cholesterol - TC, serum low-density lipoprotein cholesterol - LDL-C, and serum high-density lipoprotein cholesterol - HDL-C) and body mass index (BMI). Poisson multiple regression was performed to test the association between DS and each cardiovascular risk factor adjusted by sex, age, time spent in moderate physical activity, and functional status. The significance level adopted for the analysis was 5%.Results Among all the analyzed risk factors, only high levels of LDL-C were related to high DS (PR=1.005, CI 95% 1.002-1.008). A significant association was observed between HDL-C levels (PR=0.99, CI 95% 0.98-0.99) and SBP (PR=1.009, CI 95% 1.004-1.014).Conclusion In older adults with T2DM, the presence of DS was associated with LDL-C, HDL-C levels and SBP, even after adjusting for sex, age, physical activity level and functional capacity.

Apolipoprotein concentrations during treatment and recurrent coronary artery disease events

The effect of untreated total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) as cardiovascular risk factors in both primary and secondary prevention has been extensively investigated. The predictive value of on-treatment lipid and apolipoprotein levels on subsequent cardiovascular events is as yet uncertain. Eight hundred forty-eight patients (675 men and 173 women) with angiographically proven coronary artery disease (CAD) who received effective statin therapy (>/=30% decrease of baseline TC) were studied. We analyzed the predictive value of on-treatment levels of TC, LDL-C, triglycerides (TG), apolipoprotein A-I (apoA-I) and apolipoprotein B (apoB) on subsequent myocardial infarction (MI) and all cause mortality. On-treatment LDL-C levels were 2.55+/-0.55 mmol/L and 2.58+/-0.62 mmol/L for men and women respectively. Age-adjusted Cox regression analysis showed that only on-treatment apoA-I was predictive for future CAD events in both men and women, whereas on-treatment HDL-C was exclusively predictive in women. On-treatment apoB levels were predictive for recurrent CAD events in the total population but not after separate analysis for men and women. On-treatment levels of TC, LDL-C, and TG did not predict subsequent events. Multivariate analysis showed that on-treatment apoA-I and apoB were the only significant predictors for future cardiovascular events. On-treatment levels of TC, LDL-C, and TG were no longer associated with increased risk of recurrent cardiovascular events in CAD patients treated to target levels, which justifies the current guidelines. However, on-treatment levels of apoB and in particular apoA-I (and HDL-C in women) were significantly predictive for MI and all-cause mortality and may therefore be more suitable for cardiovascular risk assessment in this population.
