摘要

This article on determinants of pre-hypertension and hypertension in rural southwest China is an interesting study with more than 11,000 subjects. The finding that pre-hypertension is more prevalent than hypertension provides evidence of the need for early intervention in the population and intervention strategies that are appropriate for the diverse ethnic groups that exist within the population. As the authors note, the prevalence of hypertension has risen in the last decade in China. This increase follows a worldwide trend regarding the growing burden of noncommunicable diseases as a serious public health concern; moreover, half of all noncommunicable disease deaths worldwide are cardiovascular in nature. Le and colleagues were able to recruit a very large population for this study and maintain a high level of participation more than 94%. This study does not show the strong relationship to individual income that is reported in many studies; however, it does demonstrate the importance of ethnicity as it relates to pre-hypertension and hypertension. The authors suggest that genetic factors, various diet-related factors, and lifestyles may be more important determinants for blood pressure levels than individual income. What is significant in this study is that the size provides an opportunity to look at differences within what might appear to be a fairly homogenous population. In fact, the population is quite diverse, and the diversity provides evidence of the need for more tailored interventions for reducing pre-hypertension and hypertension.
