Influencing Factors of Inter-arm Systolic Blood Pressure Differences in Hypertensive Population Aged 40 Years and Younger
Objectives:To explore the influencing factors of inter-arm systolic blood pressure difference(sIAD)in young hypertensive population.Methods:A total of 12 895 young Kailuan employees aged≤40 years,who participated in the physical examination from 2010 to 2020,were enrolled in this study.All of them underwent blood pressure measurements of four limbs in supine position.Young hypertensive group(n=3 584)and young non-hypertensive group(n=3 584)were 1∶1 matched by sex and age(±1 year),and participants were further divided into sIAD＜10 mmHg(1 mmHg=0.133 kPa)and sIAD≥10 mmHg subgroups.A stepwise multivariate logistic regression model was established to analyze the determinants of sIAD≥10 mmHg.Results:The detection rate of sIAD≥10 mmHg was significantly higher in the young hypertensive group than in the young non-hypertensive group(31.72%vs.27.76%,P＜0.001).Stepwise multivariate logistic regression analysis showed that in young hypertensive population,ankle-brachial index(ABI)＜0.9,male,obesity,overweight,elevated low density lipoprotein cholesterol(LDL-C)level,and systolic blood pressure were positively associated with sIAD≥10 mmHg,while college education or above,physical exercise were negatively correlated with sIAD≥10 mmHg(all P＜0.05).In the young non-hypertensive population,ABI＜0.9,systolic blood pressure were positively correlated with sIAD≥10 mmHg,while age was negatively associated with sIAD≥10 mmHg(all P＜0.05).Conclusions:The detection rate of sIAD≥10 mmHg is higher in young hypertensive population than in young non-hypertensive population.Decreased ABI,male sex,obesity,overweight,increased LDL-C level,systolic blood pressure,college education and above,and physical exercise are the influencing factors of sIAD≥10 mmHg in young hypertensive population.
