OBJECTIVETo investigate the plasma lipid levels in a national representative sample of subjects and to determine the prevalence of dyslipidemia in the Chinese population.

METHODSPlasma lipid profile was analyzed using the data obtained during the Chinese national nutrition and health survey (CNHS) in 2002 which involved 14 252 participants at the age of 18 years or older.

RESULTSThe mean levels of total cholesterol (TC), triglyceride (TG) and high density lipoprotein cholesterol (HDL-C) in the participants were 3.81 mmol/L, 1.10 mmol/L, and 1.30 mmol/L, respectively. In the groups of participants at the age of 18-44 years, 45-59 years, and over 60 years the mean TC level was 3.70 mmol/L, 4.09 mmol/L and 4.21 mmol/L, respectively, and the mean TG level was 07 mmol/L, 1.21 mmol/L, 1.20 mmol/L, 1.29 mmol/L, 1.33 mmol/L, and 1.33 mmol/L, respectively. The prevalence of dyslipidemia in Chinese adults was 18.6% and 22.2% in males and 15.9% in females. Dyslipidemia prevalence was higher in urban districts than in rural areas (21.0% vs. 17.7%). The prevalence of hypercholesterolemia, hypertriglyceridemia, and low HDL cholesterol was 2.9%, 11.9%, and 7.4% respectively among the participants.

CONCLUSIONDyslipidemia has become one of the important health risk factors in the Chinese population. There is no significantly difference in the prevalence of dyslipidemia between the groups of participants at the age of 45-59 years and over 60 years. This study provides important lipid profile data for policy making and guideline development for the prevention of dyslipidemia in the Chinese population.

OBJECTIVETo investigate the relationship between SNPs reported in previous studies and the blood lipid level in the Tibetan population.

METHODSRandom cluster sampling was employed in 5 areas (Lhasa, Shigatse, Shannan, Nagqu, and Nyingchi). The levels of cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) from blood samples were determined and DNA was extracted for genotyping and statistical analyses.

RESULTSAmong 1 318 subjects aged >18 years enrolled in this study, 367 had dyslipidemia with a prevalence of 27.8%, of whom dyslipidemia males accounted for 33.1% and dyslipidemia females -24.5%. Results of the correlation analysis between all SNPs and TG showed that the SNPs of rs714052 and rs964184 were related to the serum TG level. Subjects with rs714052 CC genotype had the lowest TG level, and the highest TG level was found in those with rs714052 TT genotype. The serum TG level in individuals with TC genotype lied in between the above two population groups. Subjects with rs964184 CC genotype had the lowest TG level, and the highest serum TG level was noted in those with rs964184 GG genotype.

CONCLUSIONSeveral SNPs were found to be related to the serum TG level in the Tibetan population. The APOA5 gene and MLXIPL gene may be closely associated with the serum TG level in this ethnic population group.

OBJECTIVETo explore the association between dyslipidemia and different subtypes of hypertension among Zhejiang population.

METHODSFrom June to October in 2010, 19 113 local residents aged ≥ 18 years old were selected among 7571 families from fifteen counties in Zhejiang by four stage stratified-random sampling method. A self-designed questionnaire was adopted to collect information on demographic characteristics, physical activity and life style. At the same time, physical examinations including height, weight, blood pressure and blood lipids were carried out.

RESULTSA total of 19 113 participants completed the interviews, physical examinations and collected the blood samples.Excluding those who did not meet the criteria, 14 731 were finally enrolled in the study. The prevalence rates of isolated systolic hypertension (ISH), isolated diastolic hypertension (IDH), systolic and diastolic hypertension (SDH) were 7.16% (1055/14 731, standardized rate:5.46%), 4.60% (677/14 731, standardized rate:4.41%), 7.09% (1045/14 731, standardized rate:5.75%), respectively. Among normal blood pressure group, subjects with normal TC, high TC and abnormal TC were separately 10 571 (88.43%), 1173 (9.81%) and 210 (1.76%); subjects with normal HDL-C and low HDL-C were separately 6885 (57.60%) and 5069 (42.40%); subjects with normal TG, high TG, abnormal TG were separately 9952 (79.91%), 1213 (10.15%) and 1189(9.95%).In ISH group, subjects with normal TC, high TC and abnormal TC were separately 826 (78.29%), 188 (17.82%) and 41 (3.89%); subjects with normal HDL-C and low HDL-C were separately 666(63.13%) and 389 (36.87%); subjects with normal TG, high TG and abnormal TG were separately 737 (69.86%), 150 (14.22%) and 168 (15.92%). Multi factor analysis showed that high TG and abnormal TG were associated with ISH (OR (95%CI):1.43 (1.16-1.76), 1.65 (1.34-2.03) respectively). Among IDH group, subjects with normal TC, high TC, abnormal TC were separately 556(82.13%), 99(14.62%) and 22 (3.25%); subjects with normal HDL-C, low HDL-C were separately 335 (49.48%) and 342 (50.52%); subjects with normal TG, high TG, and abnormal TG separately were 402 (59.38%), 107 (15.81%) and 168 (24.82%). The multi factor analysis showed that high TG and abnormal TG could increase the risk of IDH (OR(95%CI):1.57 (1.24-1.98), 2.18 (1.76-2.70) respectively). Among SDH group, subjects with normal TC, high TC and abnormal TC were 817 (78.18%), 193 (18.47%) and 35 (3.35%); subjects with normal HDL-C and abnormal HDL-C were separately 599 (57.32%) and 446 (42.68%); subjects with normal TG, high TG, abnormal TG were separately 675 (64.59%), 164 (15.69%) and 206 (19.71%). The multi factor analysis showed that high TC, high TG and abnormal TG were also associated with the increased risk of SDH (OR (95%CI):1.38 (1.14-1.67), 1.43(1.18-1.75), 1.73 (1.43-2.10) respectively).

CONCLUSIONDyslipidemia is an important factor of different subtypes of hypertension among Zhejiang population, especially triglycerides. Dyslipidemia screening should be strengthened to reduce the risk of cardiovascular diseases.

OBJECTIVETo explore the adult lipid profile of Huayang community from 1998 to 2000 and Caoyang communities in 2001.

METHODSRepresentative serum samples of 5628 adults (aged 20 - 95 years) were obtained in Huayang and Caoyang communities during 1998.9 and 2001.11. Standard epidemiology questionnaire, physical check-ups and serum lipids data were analyzed.

RESULTSAfter standardization to Chinese census statistics of 2000, the age-and sex-standardized means of total cholesterol, HDL-C, LDL-C and triglycerides of the two communities (Huayang vs. Caoyang) were 5.01 mmol/L vs. 4.43 mmol/L, 1.28 mmol/L vs. 1.32 mmol/L, 3.37 mmol/L vs. 2.99 mmol/L, 1.97 mmol/L vs. 1.60 mmol/L respectively, and the age- and sex- standardized prevalence of dyslipidemia was 52.9% vs. 25.1%, and the prevalence for borderline dyslipidemia was 76.0% vs. 56.2%, respectively. The decreasing order of dyslipidemia prevalence of the two communities was: elevated TG, decreased HDL-C, elevated LDL-C and TC. The standardized proportions of optimal HDL-C level were only 15.7% and 16.1% in Huayang and Caoyang respectively which was much lower than these of TG, LDL and TC.

CONCLUSIONSThe standardized prevalence of adult dyslipidemia and borderline dyslipidemia in the two communities were high. Dyslipidemia of the two communities was TG and decreased.

OBJECTIVETo study the relationship between dyslipidemia and outcome in patients with acute ischemic stroke.

METHODSData about 1 568 patients with acute ischemic stroke were collected from 4 hospitals in Shandong Province from January 2006 to December 2008. National Institute of Health Stroke Scale (NIHSS) >10 at discharge or death was defined as the outcome. Effect of dyslipidemia on outcome in patients with acute ischemic stroke was analyzed by multivariate logistic regression analysis and propensity score-adjusted analysis, respectively.

RESULTSThe serum levels of TC, LDL-C, and HDL-C were significantly associated with the outcome in patients with acute ischemic stroke. Multivariate logistic regression analysis and propensity score-adjusted analysis showed that the ORs and 95% CIs were 3.013 (1.259, 7.214)/2.655 (1.298, 5.43), 3.157 (1.306, 7.631)/3.405 (1.621, 7.154), and 0.482 (0.245, 0.946)/0.51 (0.282, 0.921), respectively, for patients with acute ischemic stroke. Hosmer-Lemeshow goodness-of-fit test showed no significant difference in observed and predicted risk in patients with acute ischemic stroke (chi-square=8.235, P=0.411).

CONCLUSIONSerum levels of TC, LDL-C, and HDL-C are positively related with the outcome in patients with acute ischemic stroke.

OBJECTIVE: To study the prevalence and influencing factors of dyslipidemia in the elderly in Changsha. METHODS: Multi-stage randomized cluster sampling method was used to select 3 500 persons aged 65 and over in Changsha. Levels of serum lipids were detected and questionnaire was used to investigate the related factors (such as smoking, drinking, history of chronic diseases). RESULTS: The prevalence rate of dyslipidemia was 43.72%. The abnormal rate of serum triglyceride, cholesterol and low-density lipoprotein was 26.54%, 25.31% and 16.65%, respectively. Multiple logistic regression analysis showed that smoking, drinking, overweight or obesity were risk factors of dyslipidemia. CONCLUSION The incidence of dyslipidemia is high and the influencing factors are common among the elderly. Community health education will help improve the effect of prevention and control.

OBJECTIVETo investigate the serum levels of cholesterol, triglyceride and high density lipoprotein cholesterol in children aged 3-14 years and its influencing factors.

METHODSThe cross-sectional survey study population was a representative sample from Guangdong province obtained by multi-stage randomized cluster sampling. Serum lipids in 6188 children aged > or = 3 years were assayed using automatic biochemical instrument. The data of social and demographic status were collected by face-to-face interview, and height and weight were obtained by physical examination.

RESULTSThe age-standardized and region-weighted means of serum total cholesterol (TC), triglyceride (TG), and high density lipoprotein cholesterol (HDL-C) were 0.80 mmol/L, 3.50 mmol/L and 1.28 mmol/L, respectively. For the mean of TG, there was no difference between metropolitan and middle city, nor between rich county and poor county. For TC, it was the highest in metropolitan, and there was no difference between rich and poor county. For HDL-C, the difference existed between every two regions. The age-standardized and region-weighted prevalence of high TG, high TC and low HDL-C were 2.2%, 2.1% and 8.0%, respectively. Metropolitan, rich county, low weight and age between 7.0-9.9 years are protecting factors for high TG, and the number of family between 3-4, age between 7.0-9.9, metropolitan, middle city and poor county are risk factors for high TC. Male, family income per year between 800-9999 RMB, middle city, rich county are protecting factors for low HDL-C.

CONCLUSIONThe prevalence of abnormal serum lipid was still low compared with other regions in China. The region, number of family member, age and sex may be the important factors influencing on serum lipid levels.

OBJECTIVETo achieve the correlation between abnormal serum lipid and male erectile dysfunction (ED).

METHODSRandomly selected were 200 male patients abnormal at least in one of the four laboratory items: total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL). Their erectile function was evaluated by IIEF-5, and the correlation was studied between abnormal serum lipid and ED.

RESULTSThe incidence of ED was 47% in these patients. Age, coronary heart disease (CHD), high serum glucose, benign prostatic hyperplasia (BPH), drug, hypertension were negatively, while HDL was positively correlated with erectile function. Age, CHD, BPH and TC/HDL ratio were risk factors of ED, while HDL was a preventive one.

CONCLUSIONHyperlipidemia is an important factor of ED. HDL and TC/HDL ratio are good predictors of ED.

OBJECTIVETo study the lipids level in Kazakan individuals over 30-year-old in Fukang area of Xinjiang.

METHODSRandom cluster multistage sampling method were performed to select the subjects, and 991 individuals aged older than 30 from Fukang of Xinjiang were included. The plasma total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), plasma glucose and insulin were measured. Related adverse cardiovascular risk factors were discussed.

RESULTSThe mean plasma TC, TG, HDL-C and LDL-C of Kazakan residents over 30-year-old in Fukang of Xinjiang were (5.05 ± 1.07), (1.10 ± 0.66), (1.46 ± 0.38) and (3.06 ± 0.84) mmol/L, respectively. TC, TG and LDL-C levels in male subjects were higher than those in females (male vs female: TC: (5.19 ± 1.05) mmol/L vs (4.94 ± 1.07) mmol/L, t = 3.57, P < 0.01; TG: (1.32 ± 0.80) mmol/L vs (0.94 ± 0.46) mmol/L, t = 8.63, P < 0.01; LDL-C: (3.30 ± 0.85) mmol/L vs (2.88 ± 0.79) mmol/L, t = 8.06, P < 0.01). While the HDL-C level in male subjects was lower than that of female (male vs female: (1.32 ± 0.33) mmol/L vs (1.57 ± 0.38) mmol/L, t = 11.48, P < 0.01). The prevalence of dyslipidemia was 28.3% (280/991) in the overall populations. In the overall populations, the prevalence of hypercholesteremia, hypertriglyceridemia, high low-density lipoprotein cholesterolemia and low serum high density lipoprotein cholesterolemia were 12.6% (125/991), 6.6% (65/991), 11.0% (109/991) and 10.1% (100/991), respectively. The prevalence of individuals with borderline-high TC, TG and LDL-C were 27.0% (268/991), 7.6% (75/991) and 20.5% (203/991), respectively. The prevalence of dyslipidemia was 40.0% (172/430) in male populations. The prevalence of dyslipidemia in group aged 30 - 39, 40 - 49, 50 - 59, 60 and above were 26.2% (78/298), 26.0% (91/350), 31.2% (73/234) and 34.9% (38/109), respectively, the trend of prevalence was significant by trend test for groups comparison (χ(2) = 3.94, P < 0.05). Adjusting for age and gender, TG was positively correlated with waist circumference, abdominal circumference and BMI, the partial relation coefficients were 0.368 (P < 0.01), 0.336 (P < 0.01) and 0.331 (P < 0.01), respectively, and HDL-C was negatively correlated with waist circumference, abdominal circumference and BMI, the partial relation coefficients were -0.340 (P < 0.01), -0.339 (P < 0.01) and -0.321 (P < 0.01), respectively.

CONCLUSIONThe lipid levels of Kazakan residents from Fukang area are high and are characterized by hypercholesteremia and high low-density lipoprotein cholesterolemia, and more attention of the prevention of dyslipidemia in this populations should be paid to males, border-line abnormal and those aged over 60-year old.
