肥胖及血脂异常研究很少涉及低收入地区。本研究分析了新疆低收入地区维吾尔族农民体质指数(BMI)、超重及肥胖与多种血脂分子异常的关系,探讨贫困地区筛查高危人群的适宜策略。在新疆喀什农村对3 286名年龄≥18岁个体(男1 585人,女1 701人) 进行问卷检查、体格检查及多项血脂分子的检测。数据采用Pearson相关性、ROC、Logistic回归等统计学分析。结果显示,在男女性中,随着BMI的增加,甘油三酯(TG)、总胆固醇(TC)、低密度脂蛋白胆固醇(LDLC)的血浓度呈现递增趋势(P<0.01);男/女性TG、LDLC、TC血浓度均与BMI有显著相关性(P<0.01)。单项或多项血脂异常率均随BMI增加而上升;同一个体2个血脂指标同时异常的高危组合分别是TG+HDLC(高密度脂蛋白胆固醇)和TC+TG。Logistic联合多变量ROC曲线分析表明, 单项指标HDLC(AUC=089)在血脂异常诊断中的权重最高;而组合指标TG+HDLC(AUC=095)的权重高于其它任何组合。单因素Logistic回归分析发现,超重和肥胖是代谢综合征相关血脂指标TG、TC和HDLC异常的危险因素(P<0.05)。上述结果表明,在南疆农村贫困维吾尔族人群中,男女性超重与肥胖者均与血脂指标异常升高相关;HDLC、TG和 TC 任意两个指标同时异常,为血脂异常的高危状态。肥胖伴有“TG+HDLC”异常升高可能是血脂异常相关疾病的“集合危险因素”,在贫困地区具有临床筛查参考价值。 相似文献

A study was carried out on the serum levels of cholesterol [total (TC) and that associated with high-density lipoproteins (HDLC)] and triglyceride (TG) in 127 specimens of Scyliorhinus canicula . The values obtained were correlated with sex, size, liver weight and reproductive stage. Results showed that male dogfish have higher levels of TC and HDLC, and lower TG than female. In adult males, TC increased and HDLC decreased with both size and spermatogenesis. Females carrying capsulated eggs showed a noticeable increase in TG together with a decrease of the HDLC levels, which were apparently not related with size. 相似文献

The proportions of plasma high and low density lipoprotein cholesterol have been linked to inherited tendency for atherosclerosis in humans. Studies were conducted with Japanese quail males from lines genetically selected for high and low TC and a randombred (unselected) control line that were fed 0.0 or 0.5% cholesterol for 12 weeks. Atherosclerotic plaques were more severe in the high than in the low line quail and in those fed cholesterol compared to non-cholesterol-fed quail. Serum TG, TC, VLDLC, LDLC, and HDLC were also higher in the high than in the low line quail and in cholesterol-fed vs. non-cholesterol-fed quail. Significant interactions indicated that TC and LDLC concentrations were more affected by dietary cholesterol in the high line than in the low line. The low line quail maintained higher HDLC and lower LDLC than the high line. Regression and correlation analyses revealed that although VLDLC, LDLC, and TC were significant predictors of atherosclerosis in the high line birds, the TC/HDLC ratio was a better predictor in the low line. The Japanese quail lines used herein represent useful experimental models for studies of genetic differences in atherosclerosis in humans. 相似文献

The Objective of this study was to determine the frequency of care reactive atherosclerosis risk factors in children of parents with premature coronary heart disease observed before their 45 years of age for the promotion of the effectivity of the preventive work started in childhood and adolescent ages. METHODS: Height and weight was measured. Body mass index (BMI) was calculated. Fat analysis was performed in children with overweight. Blood pressure was measured and both 24 hour monitoring and fundoscopy were performed in cases with a blood pressure higher than 90 centile values. Fasting blood sugar (BS) level was measured. Oral glucose tolerance test was made in cases with a fasting BS level higher than 5 mmol/l. Serum total cholesterol (TC), HDL-cholesterol (HDLC) and total triglyceride (TT) levels were measured and LDL-cholesterol (LDLC) level was calculated. The plasma thiobarbituric acid reactive system (TBARS) was investigated. Statistical analyses were performed by chi2 and Student t-probes. Data of 1140 offsprings and 457 referents without any high atherosclerotic risk family history were analyzed. RESULTS: BMI of 87 offsprings was higher than the 90 centile value. The fat percent of the body of these children was higher than 40. The blood pressure of 311 children and adolescents was higher than the 90 centile value. Fasting BS level was higher than 5 mmol/l in 47 cases 17 of them showed a pathologic oral glucose tolerance test. High serum TC level was observed in 67 cases, high serum TT level was found in 8 cases. 245 offsprings had a low serum HDLC level. The plasma TBARS level was high in 241 cases. Data of referents differed significantly from those of offsprings. Their serum TC, LDLC levels and plasma TBARS level were lower, serum HDLC level was higher than that of children and adolescents with high risk atherosclerotic family history. CONCLUSION: Risk factors of atherosclerosis are detectable in children and adolescents of high risk families. The measurement of these factors may help the efficacy of the preventive work. 相似文献

Association of the methylenetetrahydrofolate reductase gene (MTHFR) C677T missense mutation (substitution of cytosine by thymine at position 677) with coronary artery disease (CAD), as well as with blood levels of various lipoprotein fractions, systolic pressure (SP), diastolic arterial blood pressures (DP), and body mass index (BMI) in patients with angiographically verified CAD and in a control group. The affected and control subjects did not differ substantially with respect to genotypic and allelic frequencies. The MTHFR gene polymorphism was not associated with variation in either total cholesterol (TC), very-low-density-lipoprotein cholesterol (VLDLC), low-density-lipoprotein cholesterol (LDLC), high-density-lipoprotein cholesterol (HDLC), or triglyceride (TG) levels. SP and DP in subjects with different MTHFR genotypes did not differ significantly. BMI tended to correlate with the C677T polymorphism of the MTHFR gene (0.05 < P < 0.1). C677T mutation frequencies in western Siberia were determined for the first time; they are about the same as in most European populations. 相似文献

Many captive chimpanzees (Pan troglodytes) are subjectively considered to be overweight or obese. However, discussions of obesity in chimpanzees are rare in the literature, despite the acknowledged problem. No study to date has systematically examined obesity in captive chimpanzees. This project develops guidelines for defining obesity in captive chimpanzees through the examination of morphometric and physiologic characteristics in 37 adult female and 22 adult male chimpanzees. During each animal's biannual physical exam, morphometric data was collected including seven skinfolds (mm), body mass index (BMI), waist‐to‐hip ratio (WHR), and total body weight (kg). The morphometric characteristics were correlated with triglycerides and serum glucose concentration, to test the utility of morphometrics in predicting relative obesity in captive chimpanzees. Abdominal skinfold (triglyceride: F=3.83, P=0.05; glucose: F=3.83, P=0.05) and BMI (triglyceride: F=10.42, p=0.003; glucose: F=6.20, P=0.02) were predictive of increased triglycerides and serum glucose in females; however no morphometric characteristics were predictive of relative obesity in males. Results suggest that no males in this population are overweight or obese. For females, there were additional significant differences in morphometric (skinfolds, BMI, WHR, total body weight) and physiologic measurements (systolic and diastolic blood pressure, red blood cells) between individuals classified overweight and those classified non‐overweight. Skinfold measurements, particularly abdominal, seem to be an accurate measure of obesity and thus potential cardiovascular risk in female chimpanzees, but not males. By establishing a baseline for estimated body fat composition in female captive chimpanzees, institutions can track individuals empirically determined to be obese, as well as obesity‐related health problems.

Overweight and obesity are usually related with high fat and calorie intake, and seriously causative of lifestyle-related diseases such as cardiovascular disorders, arteriosclerosis, and colon cancer. In this study, we propose a novel dietary therapy against overweight and obesity using mixtures of protamine and chitooligosaccharide (COS), which are known to interrupt the lipid metabolism in the body. Protamine is a dietary protein originated from salmon reproductive organ, and COS is an oligosaccharide made from chitin or chitosan by chemical or enzymatic hydrolysis. In the enzyme activity analysis in vitro, protamine and COS strongly suppressed the activity of pancreatic lipase, which is the primary enzyme for the digestion and absorption of lipids in the intestine. In in vivo animal test, the mixtures of protamine and COS significantly reduced the serum levels of triglyceride (TG), total cholesterol (T-CHO), and low density lipoprotein-cholesterol (LDLC) and inhibited the accumulation of lipids in liver tissue of Sprague Dawley (SD) rats fed high fat diets. On the other hand, they increased fecal TG and T-CHO contents. From these alterations in lipid metabolism, we verified that protamine and COS mixtures could effectively interrupt the digestion and absorption of dietary lipids in the body by inhibiting pancreatic lipase activity. In addition, protamine and COS mixtures increased the serum level of high density lipoprotein-cholesterol (HDLC), responsible for removing cholesterol from cells and protecting atherosclerosis, and therefore decreased the potential risks of cardiovascular diseases by lowering values of the atherogenic index (AI) and cardiac risk factor (CRF). Taken together, we suggest protamine and COS mixtures as a prominent dietary therapy for the prevention of overweight, obesity, and further cardiovascular diseases related with hyperlipidemia. 相似文献
