Abstract:
Objective To identify the association of oxygen saturation of arterial hemoglobin (SaO2) with late-onset hypertension in the Chinese Han population located in the Daxinganling area.Methods A total participants were selected by convenience sampling methods from the Daxinganling area.All data were collected from each person by the questionnaire record of physical examinations as well as biochemical index measuring.SaO2 was noninvasively measured with finger pulse oxymetry,the reported SaO2 was the average of three readings taken 10 seconds apart.Results There were significant differences for SaO2 within the population of individuals,the mean SaO2 values was 97.71%±6.14%,with range from 88% to 100%.There was association of SaO2 with sex,BMI and age.SaO2 level declined with BMI and age increasing.Particularly,it was found that the risk increasing to hypertension was marked association with SaO2 rapid drop.During the period from 40-50 years of age,SaO2 declined from 97.85% to 97.64%,The risk to hypertension increased more than 10 times(P<0.001).That implicated hypoxia mightinvolve in the etiology of hypertension.Conclusions The preliminary results demonstrated the rapid decline of SaO2 with lapse of age may be one of the major risk factors to hypertension,it may be helpful to explain late-onset hypertension to some extent at least.
