Abstract

Aim

The aim of this study was to estimate the prevalence, awareness, treatment, and control of dyslipidemia in Xinjiang, China.

Method

Stratified sampling method was used to select a representative sample of the general population including Chinese Han, Uygur, and Kazak in this geographic area. Seven cities were chosen. Based on the government records of registered residences, one participant was randomly selected from each household. The eligibility criterion for the study was ≥ 35 years of age.

Results

A total of 14,618 participants (5,757 Han, 4,767 Uygur, and 4,094 Kazak), were randomly selected from 26 villages in 7 cities. The prevalence of dyslipidemia was 52.72% in the all participants. The prevalence of dyslipidemia was higher in Han than that in the other two ethnic (58.58% in Han, 48.27% in Uygur, and 49.60% in Kazak, P < 0.000). The prevalence of dyslipidemia was higher in men than that in women (56.4% vs. 49.3%, P < 0.000). Among the participants with dyslipidemia, the proportion of those who aware, treat, control of dyslipidemia were 53.67%, 22.51%, 17.09% in Han, 42.19%, 27.78%, 16.20% in Uygur, 37.02%, 21.11%, 17.77% in Kazak.

Conclusion

Dyslipidemia is highly prevalent in Xinjiang. The proportion of participants with dyslipidemia who were aware, treated, and controlled is unacceptably low. These results underscore the urgent need to develop national strategies to improve the prevention, detection, and treatment of dyslipidemia in Xinjiang.

[A description on the Chinese national nutrition and health survey in 2002].

HONG-LIN XIANG, , Ke-qin Rao … (2005)

To describe the status of nutrition and health related indices in the Chinese population. A stratified multi-stage cluster sampling was used from 31 provinces, autonomous regions, and municipalities. The survey was done in 2002, including data gathered from questionnaires, interviews, physical examinations, measurement of biochemical indices, and dietary investigation. Cereals accounted for 48.5% of all the sources of energy in urban and 61.4% in rural populations. Daily mean percentages of calories for total fat were 35.0% in urban and 27.5% in rural areas. The prevalence rates of stunting and underweight were 14.3% and 7.8% respectively in young children under 5-year-old. The prevalence of vitamin A deficiency was 9.3% in Chinese children aged 3-12 years old. The total prevalence of anemia was 15.2% in general population of all ages. The prevalence of anemia in young adults was significantly higher in women than in men. The total prevalence rates of overweight and obesity were 17.6% and 5.6%, respectively. The prevalence rates of hypertension, diabetes, hypercholesteremia, hypertriglyceridemia, or low serum high density lipoprotein cholesterol were 18.8%, 2.6%, 2.9%, 11.9%, 7.4% respectively in Chinese adults aged 18 and over. The rates of awareness, treatment, and under control among hypertensives were 30.2%, 24.7%, and 25.0%, respectively. Significant regional and age differences were revealed in the dietary habit and the prevalence of various diseases. The prevalence of diseases associated with malnutrition were higher in rural than in urban areas. In contrast, the prevalence of conditions associated with overconsumption and inappropriate dietary patterns were higher in urban than in rural populations. Chinese people were currently suffering from both problems on nutrition related issues and burdens of diseases which were characterized in nutrient deficiencies and overconsumption, malnutrition and noncommunicable conditions associated with overconsumption and inappropriate diet. The difference of nutrition and health status between rural and urban people was also seen.

Serum total and lipoprotein cholesterol levels and awareness, treatment, and control of hypercholesterolemia in China.

Xigui Wu, Jingping Mo, J. Zhao … (2004)

Cardiovascular disease has become the leading cause of death in China. We examined the levels of serum total and lipoprotein cholesterol and status of awareness, treatment, and control of hypercholesterolemia in China. A cross-sectional survey in a nationally representative sample of 15,540 Chinese adults 35 to 74 years of age was conducted during 2000 to 2001. Serum cholesterol was measured by use of standard methods, and information on treatment of hyperlipidemia was obtained by use of a standard questionnaire. Age-standardized mean levels of total, HDL, and LDL cholesterol and triglycerides were 186.1, 51.7, 109.5, and 128.1 mg/dL, respectively. Of the Chinese population 35 to 74 years of age, 23.8% (112,500000 persons) had borderline high total cholesterol (200 to 239 mg/dL), and 9.0% (42,540000 persons) had high total cholesterol (> or =240 mg/dL). The population estimates for borderline high (130 to 159 mg/dL), high (160 to 189 mg/dL), and very high (> or =190 mg/dL) LDL cholesterol were 17.0% (80,122000 persons), 5.1% (24,329000 persons), and 2.7% (12,822000 persons), respectively. In addition, 19.2%, or 90 803 000 persons, had a low HDL cholesterol ( or =200 mg/dL or who were on cholesterol-lowering medications, the proportion of men and women who were aware, treated, and controlled was only 8.8% and 7.5%, 3.5% and 3.4%, and 1.9% and 1.5%, respectively. The prevalence of hypercholesterolemia was relatively high and the percentage of adults with controlled blood cholesterol was low in China. Prevention and treatment of hypercholesterolemia should be an important component of a national strategy to reduce the substantial and increasing burden of cardiovascular disease in China.

Polymorphisms in the SAA1/2 Gene Are Associated with Carotid Intima Media Thickness in Healthy Han Chinese Subjects: The Cardiovascular Risk Survey

Xiang Xie, Yi-Tong Ma, Yi-ning Yang … (2010)

Background Serum amyloid A protein (SAA) is not only an inflammatory factor, but also an apolipoprotein that can replace apolipoprotein A1 (apoA1) as the major apolipoprotein of high-density lipoprotein (HDL), which has been linked to atherosclerosis. However, the relationship between genetic polymorphisms of SAA and the intima-media thickness (IMT) of the common carotid artery in healthy subjects remains unclear. We investigated the role of SAA1 and SAA2 gene polymorphisms with IMT in a cohort of healthy subjects participating in the Cardiovascular Risk Survey (CRS) study. Methodology/Principal Findings Anthropometric and B-mode ultrasound of the carotid IMT were measured in 1914 subjects (849 men; 1065 women) recruited from seven cities in Xinjiang province, (western China). Four SNPs (rs12218, rs2229338, rs1059559, and rs2468844) were genotyped by use of the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The SNP rs12218 was associated with carotid IMT by analyses of a dominate model (P<0.001) and additive model (P = 0.003), and the difference remained significant after multivariate adjustment (P = 0.008, P<0.001, respectively). This relationship was also observed in rs2468844 after multivariate adjustment by recessive model analysis (P = 0.011) but this was not observed in rs2229338 and rs1059559 before and after multivariate adjustment. These associations were not modified by serum HDL concentration. Furthermore, there were significant interactions between rs2468844 and rs12218 (interaction P<0.001) and rs2229338 (interaction P = 0.001) on carotid IMT. Conclusion/Significance Both rs12218 of the SAA1 gene and rs2468844 of SAA2 gene are associated with carotid IMT in healthy Han Chinese subjects.
