Abstract: By using the data of 1991 National Surveillence on Chinese Student 's Physical Fitness and Health, the relatively high status o f blood pressure between the Chinese Mongolia n and Han youth w as analysed. It was found that among the youth aged 7 through 18, the incidences of relatively high blood pressure are significantly higher in the Mongolian ( 10. 6% in males and 14. 1% in females) than in the Ha n ( 5. 8% in males and 6. 4% in females) , whereas the incidences of evidently high systolic and /or diastolic blood pressure a re relatively high in the Mongolian groups too. Close relationships w ere found between the youth 's stature, body weight, Body M ass Index and the blood pressures, both in the Mongolia n and Han Groups. Among the youth with tall and broad body shape, the detecting rate o f relatively high blood pressure w as significantly high. One of the most important factors for causing the high incidence of high blood pressure in the Mongolian girls is their relative high basic diastolic blood pressure. The other affecting factors on the high incidence o f high blood pressure in the Mongolian youth w ere discussed, and the methods for the early prevention o f high blood pressure w ere also suggested by the author.
