Objective: To investigate the levels of blood pressure and serum lipids, and examine the relationship between hypertension and hyperlipidemia in Hei Yi Zhuang Chinese living in Guangxi.
Methods: A total of 1056 people of Hei Yi Zhuang ethnicity were studied. Blood pressure, body height, body weight, and serum levels of lipids and apolipoprotein were measured. The data were compared with those in 925 people of Han ethnicity, who live in the same region.
Results: Systolic blood pressure and pulse pressure were significantly higher in Hei Yi Zhuang than Han Chinese (P < 0.001). The prevalence of isolated systolic hypertension and hypertension was also significantly higher in Hei Yi Zhuang than Han Chinese (P < 0.001). Serum concentrations of total cholesterol, triglycerides, low-density lipoprotein cholesterol, and apolipoprotein (Apo) B, and the prevalence of hypercholesterolemia and hyperlipidemia were significantly lower in Hei Yi Zhuang than Han Chinese (P < 0.05). Serum concentrations of high-density lipoprotein cholesterol and the Apo A1 to Apo B ratio were significantly higher in Hei Yi Zhuang than Han Chinese (P < 0.001). The prevalence of hypertension in Hei Yi Zhuang Chinese was positively associated with triglycerides (r = 0.425, P < 0.05), whereas the prevalence of hypertension in Han Chinese was positively correlated with total cholesterol (r = 0.623, P < 0.001).
Conclusion: The present study revealed a significant difference in blood pressure and serum lipids between Hei Yi Zhuang and Han ethnic groups, and an association between hypertension and hyperlipidemia.
