目的　以人群为观察对象 ,从流行病学的角度来研究食用甜荞麦与人群血脂的关系。方法　于 1997年 6～ 9月 ,采用标准化方法 ,对内蒙古通辽市甜荞麦产区和非甜荞麦产区的居民进行了人群血脂的检测 ,统计分析采用协方差分析及标化率方法。结果　调整了年龄构成不同之后 ,主食甜荞麦地区人群TC和LDL -C平均水平明显低于非主食甜荞麦地区人群 ;HDL -C平均水平则主食甜荞麦地区人群明显高于非主食甜荞麦地区人群 ;主食甜荞麦地区人群的TC、TG和LDL -C的标化率及高血脂标化率明显低于非主食甜荞麦地区的人群。结论　食用甜荞麦可降低人群血脂水平和高血脂率 Objective To observe the population, from the epidemiological point of view to eat sweet buckwheat and the relationship between blood lipids. Methods From June to September 1997, a standardized method was used to detect the blood lipids in residents of sweet buckwheat production areas and non-sweet buckwheat production areas in Tongliao City, Inner Mongolia. Statistical analysis was conducted using the covariance analysis and standardization rate method. Results After adjusting for different age groups, the average level of TC and LDL-C in staple food sweet buckwheat area was significantly lower than that in non-staple food sweet buckwheat area; HDL-C average level was significantly higher in staple food sweet buckwheat area than in non-staple food sweet buckwheat area population ; The standardization rate and hyperlipidemization rate of TC, TG and LDL-C in staple food sweet buckwheat area were significantly lower than those in non-staple food sweet buckwheat area. Conclusion Edible buckwheat can reduce the level of blood lipid and high cholesterol in the crowd
