目的探讨不同民族人群血胰岛素与血压的关系，探讨是否胰岛素升高血压的作用存在民族差异。方法１９９６年１０～１２月，在凉山彝族自治州西昌市、布拖县和昭觉县的城镇和农村，整群抽样选择男性彝族农民、彝族移民和汉族居民作为研究对象，测量收缩压、舒张压、身高、体重和血胰岛素等指标。结果彝族农民的收缩压和舒张压水平显著低于彝族移民和汉族居民，彝族移民和汉族居民的收缩压和舒张压水平差异无显著性。彝族农民和彝族移民的血胰岛素水平差异无显著性，分别为９．０７８μＩＵ／ｍｌ和８．８９２μＩＵ／ｍｌ，但均显著高于汉族居民（６．５７７μＩＵ／ｍｌ）。多元回归分析结果表明，除彝族移民血胰岛素与收缩压呈弱相关外，各组人群血胰岛素与收缩压和舒张压均无显著性相关。结论进一步表明胰岛素与血压之间的联系尚不确定，提示血胰岛素影响血压的独立效应可能很小。
Objective To explore the relationship between blood insulin and blood pressure in different ethnic groups and to explore whether ethnic differences exist in the role of insulin in raising blood pressure. Methods From October to December 1996, male Yi peasants, Yi immigrants and Han residents were sampled by cluster sampling in urban and rural areas in Xichang, Buyou and Zhaojue counties of Liangshan Yi Autonomous Prefecture. The systolic and diastolic blood pressure , Height, weight and blood insulin and other indicators. Results The systolic and diastolic blood pressure of Yi peasants was significantly lower than that of Yi immigrants and Han residents. There was no significant difference in systolic and diastolic blood pressure between Yi immigrants and Han residents. There was no significant difference in blood insulin levels between Yi peasant and Yi immigrants, which were 9.078μIU / ml and 8.892μIU / ml respectively, but both were significantly higher than that of Han residents (6.577μIU / ml). Multiple regression analysis showed that there was no significant correlation between blood insulin and systolic blood pressure and diastolic blood pressure in all groups, except for the weak correlation between blood insulin and systolic blood pressure in Yi immigrants. Conclusion further suggests that the link between insulin and blood pressure is uncertain, suggesting that the independent effect of blood insulin on blood pressure may be small.
