Correlation of urinary albumin/creatinine ratio and blood pressure in young people / 中国医师杂志

ABSTRACT

Objective To explore the correlation of urinary albumin/creatinine ratio (urinary albumin-to-creatinine ratio,UACR) and blood pressure in young people.Methods Totally 200 cases of hypertensive patients (aged 18 ～50 years old) from January 2012 to March 2014 and 200 healthy volunteers who had medical examination in our hospital were selected with a random sampling method for staff questionnaires,biochemical tests,and physical examinations.Biochemical tests included kidney function,blood glucose,blood lipids,blood uric acid,and UACR.First,400 cases were divided into four groups (1,2,3,and 4 groups) according to UACR quartiles from low to high.Second,400 cases were divided into three groups according to their blood pressure:normal blood pressure,prehypertension,and hypertension.The correlation of UACR and different groups of blood pressure was analyzed.Results For norm blood pressure group,prehypertension,hypertension,the corresponding UACR level (median:25％ ～ 75％ quartile) was 0.8 (0.6 ～ 1.2) mg/mmol,0.9 (0.7 ～ 1.4) mg/mmol,1.0 (0.8 ～ 1.7) mg/mmol;positive UACR rate was 0,2.6％,and 34.7％,three groups UACR levels and positive UACR rate index differences were statistically significant (P ＜0.05).After age factor was adjusted for 400 cases,both systolic and diastolic blood pressures were positively correlated with UACR levels.After body mass index,age,total cholesterol,and low-density lipoprotein cholesterol were adjusted for 400 cases,compared to group 1,the ratio of prehypertension to hypertension (95％ confidence intervals) in groups 2,3,and 4 was 0.98 (0.80 ～ 1.20),1.29 (1.05 ～ 1.58),and 1.86 1.52 ～2.28).Conclusions Urinary albumin/creatinine ratio was positively correlated with prehypertension and hypertension in young people.
