A number of studies have demonstrated an association between habitual snoring and ischemic heart disease like angina pectoris, myocardial infarction and ischemic changes on the electrocardiography (ECG). Control for the influence of potential confounders has been inadequate. To further elucidate the issue we examined the association between self-assessed snoring and the relation to atherosclerotic manifestations. 804 70-year-old males and females were classified according to snoring habits. Alcohol and tobacco consumption, blood pressure, body mass index, social group, plasma lipids (triglycerides, cholesterol, high density lipoprotein), fasting blood glucose, glucose tolerance test, plasma epinephrine and norepinephrine were determined. Presence of angina pectoris, claudication intermittens, use of nitroglycerine were questioned, a resting ECG and a distal arterial pressure by use of doppler technique in the lower limbs were determined. Distal atherosclerotic manifestations was defined as complaints of claudication intermittens, pulselessness in one or more foot arteries or a foot/arm systolic pressure ratio < 0.90. ECG changes were classified in accordance to standard criteria (Minnesota codes) into positive ECG signs (Q/OS waves, S-T depressions, T-wave inversion or flattering or left bundle branch block) and definitive myocardial infarction. Snoring showed a weak positive correlation to positive ECG signs and definitive myocardial infarction, but after adjustments for the above confounders, no association was found between snoring and atherosclerotic manifestations. We conclude that, in a 70-year-old population, self-reported snoring is not associated with atherosclerotic manifestations. 相似文献

Evidence suggests that risk of chronic diseases may be programmed during the foetal and early life of the infant. With high rates of low birthweight coupled with a rapid nutritional transition, low-income countries are facing an epidemic of chronic diseases. Follow-up of a cohort of adults born during 1964-1978 in an urban slum in Lahore, Pakistan, is presented in this paper. In 695 of these adults (mean age=29.0 years, males=56%), blood pressure, fasting blood glucose, and body mass index (BMI) were measured to assess early-life predictors of risk of chronic diseases. Sixteen percent of the study population was born with a low birthweight (<2,500 g). A significant positive association (p=0.007) was observed between birthweight and BMI; additionally, adjusting for age and gender, the association with BMI was highly significant (p=0.000). Conversely, a significant negative association (p=0.016) was observed between birthweight and adult levels of fasting plasma glucose; after adjustment for age and gender, the association was more significant (p=0.005) No association was observed between birthweight and adult blood pressure. The results suggest that low birthweight may increase later risk of impaired glucose tolerance in urban Pakistani adults. Further research in this area is warranted. 相似文献

OBJECTIVE: To describe population values in cardiovascular disease (CVD) risk factors such as blood lipids, fasting insulin and glucose and blood pressure in this young age group, and calculate associations to fitness and fatness. METHODS: Participants were 369 boys (6.8 +/- 0.4 years) and 327 girls (6.7 +/- 0.4 years) from preschool classes in Copenhagen. Peak VO2, blood pressure (BP), fat content and anthropometry were determined. A fasting blood sample was analysed for insulin, glucose and blood lipids. Physical activity was measured using accelerometry. RESULTS: Mean BMI, BP and blood lipids were not different between sexes. Fat percentage assessed from skinfolds was higher (21.5% vs. 16.5%) in girls than in boys (P < 0.001). Peak VO2 and physical activity were higher in boys than in girls (8% and 9%, respectively). Peak VO2 associated to fatness independent of body weight (r = 0.41; P < 0.001). Among the CVD risk factors, fitness was associated to high-density lipoprotein (HDL) (r = 0.14; P < 0.01) and physical activity (r = 0.12; P < 0.01). Fatness assessed by skinfold was associated to blood pressure (r = 0.19-0.28; P < 0.001), to fasting glucose (r = 0.11, P < 0.05) and insulin (r = 0.17; P < 0.001). CONCLUSIONS: Mean BP in 6-7-year-old Danish children has decreased since 1979 and BMI has increased modestly since 1986/1987. The lipid profile was similar compared with data from 1973 and 1978 in Danish children. Weak relationships were found between CVD risk factors, fitness and fatness. 相似文献

Limited data suggest that folate levels are higher in patients with type 2 diabetes than in subjects with normal glucose tolerance (NGT). We compared the fasting plasma folate, glucose (FPG), body mass index (BMI), and supplementary vitamin use among male subjects with NGT, those with impaired glucose tolerance (IGT), those with newly diagnosed type 2 diabetes, and those with previously diagnosed type 2 diabetes. Plasma folate of patients with newly diagnosed diabetes and that of patients with previously diagnosed diabetes was significantly higher than that of NGT subjects (p < 0.001). Prevalence of vitamin use was lower in newly diagnosed or previously diagnosed diabetic patients compared with non-diabetic subjects. Self-rated vegetable intake was similar among the four groups. FPG, BMI, triglycerides, and systolic blood pressure correlated with plasma folate levels independently of lifestyle factors studied. These results suggest that plasma folate levels are elevated in male diabetic patients independently of health-conscious behavior that is recommended for diabetic people. 相似文献

Data for 387 men who had completed seven-day weighed dietary records as part of the Caerphilly Heart Study were examined for relations of alcohol, diet, body mass index (BMI), and other variables to blood pressure. These included age, smoking, exercise, and social class. For men not on antihypertensive treatment (n = 356) regression analysis showed that age (p less than 0.001), BMI (p less than 0.05), and alcohol intake (p less than 0.01) were significantly related to systolic blood pressure, and BMI (p less than 0.001) and alcohol intake (p less than 0.01) to diastolic blood pressure. In addition, protein intake (p less than 0.05) was significantly and inversely related to the risk of being hypertensive, but other dietary variables were not related to blood pressure. For men on antihypertensive treatment (n = 31) significant inverse correlations were observed between diastolic blood pressure and the intakes of potassium (p less than 0.01), fibre (p less than 0.001), polyunsaturated fat (p less than 0.01), and a number of other dietary variables. Reasons for these differences are discussed. 相似文献

BACKGROUND: An elevated plasma total homocysteine (tHcy) concentration seems to increase the risk of cardiovascular disease. OBJECTIVE: We evaluated the determinants of tHcy in healthy French adults. DESIGN: tHcy was measured by HPLC and fluorometric detection in 1139 women and 931 men aged 35-60 y. Subjects were participants of the Supplementation with Antioxidant Vitamins and Minerals Study, which investigates the effects of antioxidant supplementation on chronic diseases. Red blood cell folate (RBCF), plasma vitamins B-6 and B-12, and cardiovascular disease risk factors were also measured. The habitual diet was assessed in 616 subjects. Cross-sectional analyses were adjusted for age, smoking, energy intake, and concentration or intake of folate and vitamin B-6, where appropriate. RESULTS: The mean (+/-SD) tHcy concentration was 8.74 +/- 2.71 micro mol/L in women and 10.82 +/- 3.49 micro mol/L in men. In women, tHcy was positively related to age (P = 0.001), apolipoprotein B (P < 0.01), serum triacylglycerol (P < 0.01), fasting glucose (P = 0.02), and coffee and alcohol consumption (both P < 0.01) and inversely related to RBCF (P = 0.11) and plasma vitamin B-12 (P = 0.08) and vitamin B-6 (P = 0.01) intakes. In men, tHcy was positively associated with body mass index (P = 0.03), blood pressure (P < 0.02), serum triacylglycerol (P < 0.01), fasting glucose (P = 0.01), and energy intake (P < 0.01) and inversely associated with physical activity (P = 0.04), RCBF (P = 0.02), plasma vitamin B-12 (P = 0.09), and dietary fiber (P < 0.01), folate (P = 0.03), and vitamin B-6 (P = 0.09) intakes. CONCLUSION: To control tHcy, decreasing coffee and alcohol consumption may be important in women, whereas increasing physical activity, dietary fiber, and folate intake may be important in men. 相似文献

We compared the cross-sectional association of alcohol consumption with blood pressure in 810 Japanese men (JM) living in Tokyo and 946 white men (WM) living in New York. Mean systolic (JM and WM, p < 0.001) and diastolic blood pressure (JM, p < 0.002; WM, p < 0.001) were associated with alcohol consumption in both groups. Compared to abstainers, the heaviest drinkers had the highest systolic (JM, p = 0.001; WM, p < 0.01) and diastolic (JM, p < 0.002; WM, p < 0.05) blood pressures. The relation of blood pressure to alcohol intake was J-shaped in the Americans, but linear in the Japanese. Exploratory analyses revealed that the J-shape may have been due to under-reporting of heavy alcohol ingestion by American abstainers. When abstainers were excluded, the relationships were similar in both the American and Japanese. The positive association between blood pressure and alcohol consumption persisted after adjustment for age, cigarette smoking, use of antihypertensive medications, body mass index, heart rate, abdominal skinfold thickness, hematocrit, fasting blood glucose, serum uric acid levels and urinary sodium/potassium ratio. Alcohol use was also related to prevalence of hypertension. These findings confirm the presence of an independent association between alcohol intake and blood pressure in both JM and WM and suggest that, despite differences in the metabolism of alcohol, the relation of alcohol consumption to blood pressure is similar in both nationalities. 相似文献

We compared the effects of twice-daily insulin injections (n = 22) with combined insulin-glibenclamide therapy (n = 25) on glucose and lipid metabolism in 47 type II diabetic patients (age 69 (SD 9) years, BMI 25.5 (4.8) kg/m2, diabetes duration 9 (range 1-34) years) with secondary failure to sulphonylurea. After 6 months, weight gain averaged 4.2 kg (p less than 0.05), fasting blood glucose had decreased from 14.6 to 8.5 mmol/l (p less than 0.001), HbA1c from 10.9% to 8.1% (p less than 0.001). Twenty-one patients reached HbA1c levels less than 8.0%. Patients on insulin alone injected more insulin (42 vs 26 U daily, p less than 0.01). The decrease of fasting blood glucose and HbA1c was comparable in both groups (p less than 0.001). HDL-cholesterol increased (insulin: 1.10 to 1.24 mmol/l, combined therapy: 1.03 to 1.14 mmol/l, both p less than 0.01), while plasma triglycerides and NEFA decreased (p less than 0.01). Only in patients on insulin alone did total cholesterol decrease from 7.1 to 6.3 mmol/l (p less than 0.001), and LDL-cholesterol from 4.7 to 4.1 mmol/l (p less than 0.05). Apolipoproteins AI, AII and B did not show significant changes. Almost all patients reported improved wellbeing; no severe hypoglycaemias were observed. 相似文献

OBJECTIVE: Obesity is associated with hyperinsulinemia and increased level of C-reactive protein in older children and adults, but little is known about these relationships in very young children. We examined these relationships in healthy 2- to 3-year-old children. RESEARCH METHODS AND PROCEDURES: Analyses were performed on data from 491 healthy 2- to 3-year-old Hispanic children enrolled in a dietary study conducted in New York City, 1992 to 1995. RESULTS: Body mass index (BMI), ponderal index, and sum of four skinfolds were highly correlated (r > 0.75) in both boys and girls. Fasting insulin and glucose levels were only modestly correlated (r = 0.37 for boys and r = 0.28 for girls; p < 0.001 for both), but essentially all of the variability in a calculated index of insulin resistance was attributable to variability in fasting insulin level. The correlations of BMI with fasting insulin level were r = 0.16 (p < 0.05) in boys and r = 0.14 (p < 0.05) in girls. In separate multivariate regression analyses adjusting for age and sex, BMI and ponderal index were associated with fasting plasma insulin level (p < 0.001 for both obesity measures). In multivariate regression analyses adjusting simultaneously for age, sex, and either BMI or ponderal index, fasting insulin level, but not these obesity measures, was associated with C-reactive protein level. DISCUSSION: Obesity is associated with higher fasting insulin level, and fasting insulin is associated with C-reactive protein level, in healthy 2- to 3-year-old children. 相似文献

Guar gum improves insulin sensitivity, blood lipids, blood pressure, and fibrinolysis in healthy men. 总被引:1,自引:0,他引:1
A double-blind, placebo-controlled, cross-over study was carried out in 25 healthy, nonobese middle-aged men to test the effect of guar gum on glucose and lipid metabolism, blood pressure, and fibrinolysis. Ten grams guar or placebo granulate was given three times a day for 6 wk with a 2-wk run-in before and a wash-out period after. Decreases in fasting blood glucose (P < 0.001), cholesterol (P < 0.001), triglycerides (P < 0.05), plasminogen activator inhibitor-1 activity (P < 0.01), systolic blood pressure (P < 0.01), and diastolic blood pressure (P < 0.001) were seen during guar treatment when compared with placebo. Insulin sensitivity, measured with the euglycemic-clamp technique, increased (P < 0.01), adipose tissue-glucose uptake measured in vitro increased (P < 0.001), and 24-h urinary excretion of sodium and potassium increased (P < 0.001) during guar treatment. Fasting plasma insulin, renin, aldosterone, and fibrinogen concentrations as well as skeletal-muscle electrolytes, urinary catecholamines, and body weight remained unaltered. These findings support a role for guar in the treatment of the metabolic syndrome in which insulin resistance seems to play a pivotal role. 相似文献

INTRODUCTION: Cardiovascular disease (CVD) is one of the major health and social problems in Iran. The aim of this study is to determine the predictors of CVD risk factors in adolescents residing in district 13 of Tehran. METHODS: Dietary intake assessment was undertaken with two separate 24-hour recall interviews with adolescents aged 11-18 years, selected from among 15005 subjects who were participants of the Tehran Lipid and Glucose Study. After excluding the under- and over-reporters, 290 adolescents remained in the study. Data related to cigarette smoking was collected. Height and weight were assessed and body mass index (BMI) was calculated. Blood pressure was measured twice at intervals in a seated position. Serum cholesterol, triglycerides, and high-density lipoprotein (HDL) concentrations were measured in a blood sample after 12 hours of fasting, and low-density lipoprotein (LDL) was calculated. To determine the predictors of CVD risk factors stepwise linear regression was used. RESULTS: There were strong positive correlations between BMI and both systolic and diastolic blood pressure in girls: (beta = 1.8, p < 0.001; beta = 0.8, p < 0.001) and boys (beta =0.04, p < 0.001; beta = 0.05, p < 0.01). There was an inverse association between calcium intake and systolic (beta = -0.16, p < 0.05) and diastolic blood pressure in boys (beta = -0.36, p < 0.01), as well as inverse association between calcium intake and systolic (beta = -1.2, p < 0.05) and diastolic blood pressure (beta = -0.05, p < 0.05) and serum triglycerides (beta = -0.1, p < 0.01) in girls. Positive correlations were found between BMI and cholesterol in girls (beta = 0.2, p < 0.01) and boys (beta = 0.31, p < 0.01). CONCLUSION: Certain dietary and life style factors predict CVD risk factors in Tehranian adolescents. 相似文献

Larger thigh and hip circumferences are associated with better glucose tolerance: the Hoorn study 总被引:2,自引:0,他引:2

OBJECTIVE: A higher waist-to-hip ratio, which can be due to a higher waist circumference, a lower hip circumference, or both, is associated with higher glucose levels and incident diabetes. A lower hip circumference could reflect either lower fat mass or lower muscle mass. Muscle mass might be better reflected by thigh circumference. The aim of this study was to investigate the contributions of thigh and hip circumferences, independent of waist circumference, to measures of glucose metabolism. RESEARCH METHODS AND PROCEDURES: For this cross-sectional study we used baseline data from the Hoorn Study, a population-based cohort study of glucose tolerance among 2484 men and women aged 50 to 75. Glucose tolerance was assessed by a 75-g oral glucose tolerance test; hemoglobin A(1c) and fasting insulin were also measured. Anthropometric measurements included body mass index (BMI) and waist, hip, and thigh circumferences. RESULTS: Stratified analyses and multiple linear regression showed that after adjustment for age, BMI, and waist circumference, thigh circumference was negatively associated with markers of glucose metabolism in women, but not in men. Standardized beta values in women were -0.164 for fasting, -0.206 for post-load glucose, -0.190 for hemoglobin A(1c) (all p < 0.001), and -0.065 for natural log insulin levels (p = 0.061). Hip circumference was negatively associated with markers of glucose metabolism in both sexes (standardized betas ranging from -0.093 to -0.296, p < 0.05) except for insulin in men. Waist circumference was positively associated with glucose metabolism. DISCUSSION: Thigh circumference in women and hip circumference in both sexes are negatively associated with markers of glucose metabolism independently of the waist circumference, BMI, and age. Both fat and muscle tissues may contribute to these associations. 相似文献

OBJECTIVE: The role of leptin in the association between body mass, central adiposity, and blood pressure (BP) is controversial. This study evaluated the relationship between leptin and BP in relation to body mass index (BMI) and fat distribution in a large sample of untreated male adults. RESEARCH METHODS AND PROCEDURES: The study population was made up of 457 untreated male employees of the Olivetti factory in Naples. Plasma leptin, complete anthropometry, BP, and relevant biochemical variables were measured. RESULTS: Log-transformed plasma leptin levels were directly associated with BMI (r = 0.661, p < 0.001) and waist circumference (r = 0.630; p < 0.001). Leptin also correlated with systolic (r = 0.258) and diastolic (r = 0.277) BP (p < 0.001). The association between leptin and BP was maintained after accounting for age, BMI (or waist circumference), log-insulin, and serum creatinine (p < 0.01); this association was stronger than that with BMI. Logistic regression analysis showed that an increased prevalence of hypertension (BP >or= 140 and/or 90 mm Hg) was associated with high plasma leptin levels when controlling for age and waist circumference (odds ratio, 1.99; 95%CI, 1.06 to 3.72) or for age and BMI (odds ratio, 1.92; 95%CI, 1.02 to 3.61). DISCUSSION: A graded positive relationship between plasma leptin levels and BP was observed in this sample of untreated male adults. This association was independent of age, BMI, abdominal adiposity, and fasting plasma insulin.

目的 了解江苏省太仓市2型糖尿病(T2DM)及糖尿病前期(IGR)的流行现状,并分析相关危险因素.方法 采用多阶段随机整群抽样方法,选取太仓市1,319名18~65周岁的常住居民为调查对象进行横断面调查,并对研究对象进行问卷调查和体格检查,留取空腹和餐后2h静脉血进行生化指标测定.结果 不计已确诊的糖尿患者,太仓市居民T2DM的患病率为6.1%、IGR患病率为16.0%.在IGR人群中,空腹血糖受损(IFG)患病率为4.09%、糖耐量受损(IGT)患病率为11.9%.IGR组和T2DM组分别同正常糖耐量组(NGT)组比较,腰围、臀围、体质指数、腰臀比、收缩压、舒张压、空腹血糖和餐后2小时血糖均高于NGT组,差异有统计学意义(P<0.05).多因素logistic回归分析显示,年龄、性别、高血压、腹型肥胖、体质指数、糖尿病家族史是太仓市城乡居民糖尿病前期及糖尿病患者的重要危险因素.结论 太仓地区的IGR患病率较高,社区全科团队应将年龄较大、男性、糖尿病家族史、BMI指数超标、腹部肥胖、患有高血压等危险因素的居民作为重点对象进行健康教育干预. 相似文献
