Diabetes and other CVD risk factors rocket in Chinese population
MedWire News: Morbidity caused by risk factors for cardiovascular disease (CVD) including diabetes has rapidly increased in the Chinese population, with multiple risk factors often being present in the same individual, report researchers.
With rapid changes in urbanization, industrialization, and lifestyle, the morbidities related to being overweight, obese, hypertensive, dyslipidemic, or diabetic all present an accelerated trend in the Chinese population, say Zhao-Jun Yang (China-Japan Friendship Hospital, Beijing) and team.
As reported in the European Heart Journal, the researchers analyzed data from the 2007-2008 China National Diabetes and Metabolic Disorders Study, which included data for a nationally representative sample of 46,239 adults, of 20 years of age or older, across 152 cities and 112 counties.
The team analyzed the prevalence of CV risk factors and nonfatal CVD in the Chinese population and compared the family background and traditional risk factors for coronary heart disease (CHD) and stroke.
The researchers found that the presence of CVD increased with age in both males and females. The prevalence of being overweight or obese, hypertension, dyslipidemia, or hyperglycemia was 36.7, 30.1, 67.4, and 26.7% in men; and 29.8, 24.8, 64.0, and 23.6% in females, respectively.
In the total sample, the prevalence of having one, two, three, or four or more of the five defined risk factors (smoking, overweight or obese, hypertension, dyslipidemia, or hyperglycemia) was 31.2, 27.4, 17.8, and 10.2%, respectively.
Further analysis also revealed that, after adjusting for gender and age, the odds ratio for CVD for those who had one, two, three, or four or more risk factors was 2.4, 4.2, 4.9, and 7.2, respectively, when compared with patients with no risk factors.
Furthermore, "the prevalence of prediabetes and diabetes increased 300% according to our data compared with that seen in a 1994 national survey," say the authors.
They say that with the effects of rapid changes in lifestyle on morbidity and with multiple risk factors being clustered in the same individual, the progression of CVD "remains grim".
"Based on the results of our present study, departments of public health management and clinicians should provide adequate risk assessment strategies and further preventative strategies to attenuate the rapid rise in cardiovascular morbidity," conclude Yang and team.
