Abstract

Objective: The aim of this study was to investigate the association of both peripheral and central systolic blood pressure (pSBP and cSBP) with urinary albumin-to-creatinine ratio (UACR) in a community-based population in Beijing. Methods: A total of 3 479 Chinese subjects with questionnaire, UACR, pSBP, and cSBP data available were included from an atherosclerosis cohort of Peking University First Hospital in Shijingshan District, Beijing followed up from April to July in 2014. Multivariate linear regression analyses were used to examine the effect of pSBP and cSBP on lnUACR, and further tests for interactions were performed according to associated covariates. Results: Subjects were (59.0±8.6) years old, 36.2% (n=1 260) were male, 46.0% (n=1 595) had hypertension, and 20.2% (n=700) had diabetes. The pSBP and cSBP was (126.9 ± 16.4) mmHg (1 mmHg=0.133 kPa), and (136.3 ± 16.7) mmHg, respectively. P(50) (P(25)-P(75)) of UACR was 6.2 (4.2-11.1) mg/g. Both pSBP and cSBP were linearly associated with lnUACR adjusted for age, sex, body mass index, smoking status, drinking status, triglyceride, HDL-C, LDL-C, fasting glucose, creatinine, history of cardiovascular disease, antihypertensive and hypoglycemic agents (every 10 mmHg increase for pSBP: β=0.12, 95%CI: 0.10-0.15, P<0.001; for cSBP: β=0.11, 95%CI: 0.09-0.14, P< 0.001). The relationships were remained in subgroups such as non-hypertension group, non-diabetes group, normal UACR group, and 3-combination group (every 10 mmHg increase for pSBP: β=0.09, 95%CI: 0.05-0.13; β=0.12, 95%CI: 0.10-0.15; β=0.07, 95%CI: 0.06-0.09; β=0.08, 95%CI: 0.05-0.12. for cSBP: β=0.07, 95%CI: 0.04-0.11; β=0.11, 95%CI: 0.08-0.13; β=0.07, 95%CI: 0.05-0.08; β=0.06, 95%CI: 0.03-0.09, all P<0.001). Furthermore, analyses for interaction found that both pSBP and cSBP were more strongly associated with lnUACR in males, current smokers and subjects with high serum creatinine level (≥87 µmol/L) when compared with females, non-current smokers and subjects with low serum creatinine level (<87 µmol/L), respectively (all P for interaction<0.05). Conclusion: The results showed that both pSBP and cSBP were independently associated with UACR in this Chinese community-based population even in low risk population suggesting well-controlled both peripheral and central blood pressure may reduce urinary albumin. Males, current smokers and subjects with higher serum creatinine should pay more attention to the impacts of pSBP and cSBP on UACR.
