RÉSUMÉ

Excessive sodium/salt intake is the leading dietary risk factor for the loss of healthy life in the Chinese population. The "Healthy China 2030" Action Plan set the goal of reducing salt intake by 20% by 2030. However, salt intake in China is still at a very high level in the world, with adults reaching 11 g/d, more than twice the recommended limit of 5 g/d. The current policies and action plans of China have targeted catering workers, children, adolescents, and home chefs in salt, oil, and sugar reduction actions. However, there are still obvious deficiencies in the coordinated promotion and implementation. This study, therefore, proposed a set of comprehensive strategies (named CHRPS that is composed of communication and education, salt reduction in home cooking, salt reduction in restaurants, reducing salt content in pre-packaged food, and surveillance and evaluation) and key implementation points for further deepening the salt reduction action in China. These strategies were developed based on the main sources of dietary sodium for Chinese residents, the status of "knowledge, attitude and practice" in salt reduction, evidence of effective intervention measures, existing policies and requirements, and the salt reduction strategies of the World Health Organization and experience from some other countries. As a scientific reference, the CHRPS strategies will help the government and relevant organizations quickly implement salt reduction work and facilitate the earlier realization of China's salt reduction goal.

RÉSUMÉ

Major and profound changes have taken place in China over the past 30 years. Rapid socioeconomic progress has exerted a great impact on lifestyle, ranging from food, clothing, working and living conditions, and means of transportation to leisure activities and entertainment. At the same time, new health problems have emerged, and health services are facing new challenges. Presently, cardiovascular diseases (CVD) are among the top health problems of the Chinese people, and pose a serious challenge to all engaged in the prevention and control of these diseases. An epidemic of CVD in China is emerging as a result of lifestyle changes, urbanization and longevity. Both national policy decision-making and medical practice urgently need an authoritative report which comprehensively reflects the trends in the epidemic of CVD and current preventive measures. Since 2005, guided by the Bureau of Disease Prevention of the Ministry of Health of the People's Republic of China and the National Center for Cardiovascular Diseases of China, nationwide experts in the fields of epidemiology, clinical medicine and health economics in the realms of CVD, cerebrovascular disease, diabetes and chronic kidney disease, completed the Report on Cardiovascular Diseases in China every year. The report aims to provide a timely review of the trend of the epidemic and to assess the progress of prevention and control of CVD. In addition, as the report is authoritative, representative and readable, it will become an information platform in the CVD field and an important reference book for government, academic institutes, medical organizations and clinical physicians. This publication is expected to play a positive role in the prevention and control of CVD in China. We present an abstract from the Report on Cardiovascular Diseases in China (2010), including trends in CVD, morbidity and mortality of major CVDs, up-to-date assessment of risk factors, as well as health resources for CVD, and a profile of medical expenditure, with the aim of providing evidence for decision-making in CVD prevention and control programs in China, and of delivering the most authoritative information on CVD prevention and control for all citizens.

RÉSUMÉ

Objective To explore the association between risk factors of cardiovascular diseases (CVD) and insulin resistance in a cross-sectional study.Methods An investigation on risk factors of CVD was carried out using stratified-random sampling method among 1475 participants in Beijing.Homeostasis model assessment index(HOMA) was calculated to assess the insulin resistance in 1359 non-diabetic subjects aged 25-64 years.Insulin resistance was defined as HOMA index (fasting glucose in mmol/L×fasting insulin in mU/L/22.5) in the top quartile of the studied population.Results The degree of correlation between risk factors and natural logarithm of HOMA index in descending order were glucose,body mass index (BMI),triglyceride ( TG ),waist circumstance,high density lipoprotein- cholesterol (HDL-C),uric acid,diastolic blood pressure,systolic blood pressure and total cholesterol(TC) (all P<0.01 ).After adjusting factors as sex and age,glucose (r=0.49),BMI(r=0.44),TG (r=0.44),waist circumstance (r=0.41),uric acid (r=0.33) and HDL-C (r=-0.32),the systolic blood pressure (r=0.20),diastolic blood pressure (r=0.18) and TC (r=0.16) were independently correlated with HOMA index (P<0.001).Sex(OR=1.75) ,low HDL-C(OR= 1.80),hyperuricemia(OR=2.11 ),high TG(OR=2.14) and central obesity(OR=2.68)appeared to be independently correlated to insulin resistance in multiple logistic regression analysis.Conclusion The risk factors of CVD as low HDL-C,high TG,central obesity and hyperuricemia were independently correlated to insulin resistance.

RÉSUMÉ

<p><b>OBJECTIVE</b>To establish cut offs and risk stratification of dyslipidemia in Chinese adults.</p><p><b>METHODS</b>Data from 2 widely cited studies: the PRC-US Collaborative Study of Cardiovascular and Cardiopulmonary Epidemiology and the China Multi-Provincial Cardiovascular Cohort Study, with a total of 40 719 Chinese adults, age 35 to 64 at baseline, about half men and half women, followed up for a total of 345 140.5 person years, were used to analyze the relationship between dyslipidemia and ischemic cardiovascular diseases (ICVD, including coronary heart events and ischemic stroke events) using a common data analysis protocol co-developed by the scientists from the 2 studies. The relative risk was estimated with the Cox proportional hazard model adjusting for other conventional cardiovascular risk factors. The 10-year absolute risk of ICVD for a 50 years-old person at different risk factor combinations was used to develop the risk stratification.</p><p><b>RESULTS</b>(1) There was a continuous linear relationship between baseline TC (or LDL-C) and ICVD risk without a threshold; (2) The incidence (absolute risk) of ICVD was similar for LDL-C < 3.37 mmol/L (130 mg/dl) and for TC < 5.18 mmol/L (200 mg/dl); and similar for LDL-C < 4.14 mmol/L (160 mg/dl) and for TC < 6.22 mmol/L (240 mg/dl); (3) The absolute ICVD risk for TC > or = 6.22 mmol/L (240 mg/dl) was slightly less but close to that for grade 1 hypertension; (4) ICVD risk increased as HDL-C decreased; (5) No significant association was found between baseline TG and subsequent ICVD; (6) At any TC level, the absolute ICVD risk for those having only hypertension was higher than that for those having 3 other risk factors.</p><p><b>CONCLUSION</b>The cut offs for diagnosis of dyslipidemia in Chinese adults can refer to those used in relevant international guidelines: TC < 5.18 mmol/L (200 mg/dl) [or LDL-C < 3.37 mmol/L (130 mg/dl)] as normal, TC 5.18 - 6.19 mmol/L (200 - 239 mg/dl) [or LDL-C 3.37 - 4.12 mmol/L (130 - 159 mg/dl)] as borderline high, and TC > or = 6.22 mmol/L (240 mg/dl) [or LDL-C > or = 4.14 mmol/L (160 mg/dl)] as high; HDL-C < 1.04 mmol/L (40 mg/dl) as low, 1.04 - 1.53 mmol/L (40 - 59 mg/dl) as normal and > or = 1.55 mmol/L (60 mg/dl) as optimal.

RÉSUMÉ

<p><b>OBJECTIVES</b>To compare changes in body mass index (BMI), prevalence of over weight and obesity of the population in a community cohort of Peking University during 1992 to 2002, and to study their characteristics of individual BMI.</p><p><b>METHODS</b>Totally, 1 985 individuals aged 35-64 years were selected from Peking University community with stratified random sampling method for baseline survey by physical examinations and questionnaire interviews to collect relevant data in 1992. And, a follow-up survey was conducted for each individual of the cohort in 2002. Data were analyzed for 1 437 individuals with complete records of the two surveys.</p><p><b>RESULTS</b>(1) In the period from 1992 to 2002, weight increased averagely 4.89 kg in men and 3.08 kg in women, respectively, and BMI increased to 25.22 kg/m2 in 2002 from 23.49 kg/m2 ten years ago in men and to 25.02 kg/m2 from 23.30 kg/m2 in women. (2) Prevalence of overweight increased by 47.8% in men and 29.5% in women, and prevalence of obesity increased by 124.2% in men and 131.3% in women, respectively. (3) 74.9% of men with overweight ten years ago remained overweight and 22.9% of them became obese in 2002. 85.7% of men with obesity ten years ago remained obese in 2002. 58.2% of women with overweight ten years ago remained overweight and 34.5% of them became obese in 2002. 93.7% of women with obesity ten years ago remained obese in 2002.</p><p><b>CONCLUSIONS</b>Mean BMI and prevalence of overweight and obesity of population in Peking University community increased during 1992 to 2002. Most of those with overweight or obesity ten years ago remained overweight or obese and few of them became normally weighed ten years later. Those with overweight BMI were more liable to become obese than those with normal BMI. All these results indicated once overweight or obesity established, it was difficult to be reversed. Therefore, the key to control overweight and obesity rests on its earlier prevention.</p>

RÉSUMÉ

<p><b>OBJECTIVE</b>To evaluate the trends of cardiovascular disease (CVD) risk factors between 1992 and 2002 (10 years) in a cohort of Beijing.</p><p><b>METHODS</b>Two separate surveys were carried out for a cohort (2740 subjects) in 1992 and 2002 according to methods of the WHO MONICA project. Systolic blood pressure (SBP) and diastolic blood pressure (DBP), body mass index (BMI), waist circumference (WC) and hip circumference (HC), serum total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), triglyceride (TG), glucose, prevalence of hypertension, rate of hypertension treatment and control were compared between 1992 and 2002.</p><p><b>RESULTS</b>(1) Comparisons of the same age groups showed that CVD risk factors increased significantly during the 10 year period from 1992 to 2002. (2) Nineteen percent of the subjects with optimal BP in 1992 became hypertensive in 2002, and 45.3% of normal BP subjects in 1992 became hypertensive in 2002. (3) 43.8% of the subjects with normal blood lipid in 1992 became hyperlipidemia in 2002. (4) 37.0% of the subjects with normal BMI in 1992 became overweight in 2002, and 43.7% of subjects with normal WC in 1992 became high WC in 2002. (5) 14.6% of the subjects without metabolic syndrome in 1992 became with metabolic syndrome in 2002.</p><p><b>CONCLUSIONS</b>The levels of CVD risk factors in this cohort increased significantly in a 10 year period from 1992 to 2002. Most of the risk factors were related to unhealthy life styles. To modify unhealthy life style and control the increasing rate of major risk factors are the key to reduce CVD incidence.</p>

RÉSUMÉ

<p><b>OBJECTIVE</b>To explore the association of free fatty acid (FFA) with the metabolic syndrome (MS) and its components.</p><p><b>METHODS</b>A cross-sectional study on cardiovascular risk factors was carried out in a natural population of Beijing in 1999, recruited by a stratified-random sampling method. The association of FFA with MS and its components was analyzed in a sample of 997 subjects aged 35-64 years.</p><p><b>RESULTS</b>(1) The prevalence of MS increased with FFA level. (2) After adjustment for age, sex, smoking, alcohol consumption, body mass index (BMI) and insulin resistance index using a multi-variable logistic regression, FFA was significantly associated with MS. The odds ratio (OR) for the second, third, and fourth quartiles of FFA was 3.1, 3.1 and 4.1, respectively (all P < 0.001). (3) FFA correlated significantly with triglycerides (TG), glucose, systolic blood pressure, diastolic blood pressure, and waist circumference in the correlation analysis (all P < 0.001). The strongest correlation was found between FFA and TG, but no significant correlation was found between FFA and high-density lipoprotein cholesterol (HDL-C). (4) After adjustment for other factors in the logistic regression, FFA was significantly associated with central obesity, hypertriglyceridemia, hypertension, and hyperglycemia, but not with low HDL-C. (5) After adjustment for FFA, BMI and other factors, insulin resistance was also associated with central obesity, hypertriglyceridemia, low HDL-C, and hyperglycemia, but not hypertension.</p><p><b>CONCLUSION</b>FFA was associated with MS and four of the five components of MS, i.e. central obesity, hypertriglyceridemia, hypertension, and hyperglycemia. It is suggested that FFA be one of the underlying pathogenic factors or risk factors for MS. FFA and insulin resistance may lead to MS through different but synergistic mechanisms.</p>

RÉSUMÉ

<p><b>OBJECTIVE</b>To explore the association of metabolic syndrome with CVD in a cohort study involving 11 provinces.</p><p><b>METHODS</b>A cohort study was carried out in a population of 27 739 subjects (age 35 - 64 years). A baseline survey on the risk factor of cardiovascular disease was done in 1992. Incidence rate and relative risk were calculated for metabolic syndromes.</p><p><b>RESULTS</b>(1) The age-standardized incidence rate of cardiovascular disease for metabolic syndromes (MS) was higher than those without (MS) in this cohort (MS 652.3/100,000, not MS 206.7/100,000, RR = 3.12, P < 0.001). (2) The incidence rate of cardiovascular disease for patients with hypertension but low HDL cholesterol and high waist was the highest (910.2/100,000 in man, 930.7/100,000 in woman) among all metabolic syndromes patients. (3) The predictive risk factors for cardiovascular disease were age, cigarette smoking, BMI, total cholesterol and metabolic syndrome in men, with age, BMI and metabolic syndrome in women.</p><p><b>CONCLUSION</b>The incidence rate of cardiovascular disease on the metabolic syndrome was high in 11 provinces in China. Age, BMI and metabolic syndrome were the predictive risk factors of cardiovascular disease (especially of cerebrovascular disease). It is essential to prevent risk factors of cardiovascular disease in primary and secondary prevention programs in general population.</p>
