A comparative study on the relationship between cerebral vascular hemodynamics and risk factors of stroke in Han and Hani nationality groups in south Yunnan / 中国基层医药

ABSTRACT

Objective To investigate the difference between Han nationality residents and the Hani nationality residents in southern Yunnan about the effects of stroke risk factors on cerebral vascular hemodynamic indicators.Methods In the cohort crowds,Hani nationality outpatient patients were selected as the Hani nationality group,the Han nationality outpatient patients with the same gender and similar age were randomly selected as the Han nationality group with the ratio of nearly 1 ∶ 3.The risk factors of stroke and the differences of the hemodynamic indicators were compared between the two groups.Results The dyslipidemia proportion of the Hani nationality group was lower than that of the Han nationality group [48 cases (11.5 ％) vs.257 cases (17.5 ％),x2 =8.867,P =0.003],and the drinking proportion of the Hani nationality group was higher than that of the Han nationality group [79 cases (18.9％) vs.214 cases(14.6％),x2 =4.498,P =0.034],the other risk factors exposure rates had no statistically significant differences between the two groups (all P ＞ 0.05).The ratio of numbers of cerebral vascular hemodynamic indicators below 75 points(optimum truncation points) in the Hani nationality group and the Han nationality group were 30.3％ and 31.9％,respectively,the proportion of the two groups of integral value distribution had statistically significant difference (x2 =12.614,P ＜ 0.01);Vmean (leftt =0.632,P =0.527;rightt =0.642,P =0.532),Vmin (leftt =-0.349,P =0.727;rightt =-0.540,P =0.589),Wv(leftt =0.297,P =0.767;rightt =1.119,P =0.263),Zcv(leftt =0.297,P =0.767;rightt =1.247,P =0.213),Rv(leftt =0.837,P =0.403;rightt =1.222,P =0.222),DR(leftt =0.720,P =0.482;rightt =0.396,P =0.692),Cp(leftt =0.614,P =0.539;rightt =1.486,P =0.138) and other indicators of the two groups had no statistically significant differences.Conclusion The Hani nationality residents'stroke risk factors and CVHI integral distribution in different age groups are different from Han people in southern Yunnan.
