Evolving Cardiovascular Disease Prevalence, Mortality, Risk Factors, and the Metabolic Syndrome in China

Abstract

The rapid growth transformation of China from a rural agrarian society to an industrial society with increased wealth has impacted the cardiovascular health of the entire population. The increasing prevalence of cardiovascular disease (CVD) and CVD risk factors mirror in some regards the disease prevalence in western industrialized countries and in other areas present unique public health issues. This article reviewed recent population surveys, reports, and clinical trials conducted in China. It was found that the prevalence of CVD and many of the risk factors such as hypertension, obesity, and diabetes contributing to disease mortality are increasing in China. However, compared with the United States, disease mortality is lower. Also, cerebrovascular disease is far more common than ischemic heart disease in China. The low prevalence of disease may suggest a reduced role of diagnostic imaging studies as compared with the US, while the increased percentage of strokes may point to the need for widely available emergent computed tomography (CT) imaging in hospitals in China. This article also discusses the occurrence of metabolic syndrome, obesity, glucose intolerance, diabetes, and their unique features in the Chinese population. Of interest, compared with the Caucasian cohort of the same body mass index (BMI), the Chinese had a higher percentage of body fat. Metabolic syndrome was found to be associated with increased cardiovascular mortality rate. With one fifth of the world's population, China can anticipate a dramatic rise, in absolute numbers, of CVD. It is imperative that national and regional programs are initiated to detect and treat the disease. Copyright © 2009 Wiley Periodicals, Inc.

Physiological Differences Across Populations Reflecting Early Life and Later Life Nutritional Status and Later Life Risk for Chronic Disease

“…But the resulting increases in weight beyond a certain level may also have had negative consequences in many countries (Beltran Sanchez and Crimmins 2013; Crimmins et al 2013; Popkin 2006). Higher adult weight has been linked to multiple negative physiological outcomes including hypertension, insulin resistance, dysregulated lipids and diabetes (Clarke et al1997; Zheng et al 2009). …”

Matsuda–DeFronzo insulin sensitivity index is a better predictor than HOMA-IR of hypertension in Japanese: the Tanno–Sobetsu study

“…Hypertension, diabetes and dyslipidemia are lifethreatening risk factors of cardiovascular events worldwide [1][2][3][4] and these lifestyle-related diseases tend to co-exist in the same individuals. [5][6][7] Insulin resistance (IR) is not only a hallmark of type 2 diabetes mellitus and metabolic syndrome but also frequently present in non-diabetic patients with hypertension.…”

Does falling testosterone with age among men underlie the increase in ischaemic heart disease

“…However, the trend of CVD risk factor clusters with age is similar in the USA and in China,8 where older men have a higher CVD risk factor burden in both countries 9 10. The rapid economic transition in China has brought changes in diet, such as greater consumption of a high-fat diet and higher frequency of food consumption away from home 11.…”

“…The rapid economic transition in China has brought changes in diet, such as greater consumption of a high-fat diet and higher frequency of food consumption away from home 11. However, changes in diet are likely to affect the whole population, and so would contribute to a period effect, as reflected by the increase in CHD mortality in all age groups in Chinese men from 1984 to 1999 8. Of course, older Chinese men could have been the first group to start consuming a Westernised diet, with the attendant risks, although usually young people are the first to follow new trends.…”
