Abstract:
Objective To explore the spatial distribution of hypertension in recruited Chinese male youth.Methods Maps of spatial distribution on hypertension detection rates in recruited Chinese male youth were produced,using a spatial local interpolation technique with the ArcGIS8.1 software.Cross-validation techniques were used to evaluate the fitness of the distribution maps.Results The spatial distribution of hypertension detection rates in recruited Chinese male youth in 2001 showed that the detectable rate of the hypertension of the recruited male youth was distributed in sections.The sections with a higher rate included Hebei,Shandong and Beijing,as the center of the northern area,and Guangxi,as the center of the southern area.The detectable rate of diastolic pressure was found higher in the areas of northeast and north China than in other places.The prediction error of the cross-validation indicated that the spatial distribution maps of hypertension detecting rates had good fitness to hypertension detecting rates of recruited Chinese male youth.Conclusion There existed in significant spatial difference in hypertension detecting rates of recruited Chinese male youth.Influence of geographical environment,climate,and economy on adolescents' blood pressure should be further studied.
