Abstract:
Objective To investigate the association between cumulative exposure blood to pressure (cum BP) and new-onset chronic kidney disease (CKD).Methods In this prospective cohort study,101 510 employees of Kailuan Group receiving annual health examination during 2006 to 2007 were observed.The participants received the second,third,and fourth annual health examinations during 2008 to 2009,2010 to 2011,and 2012 to 2013 year respectively.Their urinary and serum creatinine were tested,and participants with incomplete SBP,DBP data and CKD were excluded.Further excluding those who somehow failed to take annual health examination,with incomplete data,or new-onset CKD 27 809 participants were selected in the analysis.According to cum BP exposure quintile grouping:Q1 ＜ 3.70 scores;Q2:3.70-6.16 scores;Q3:6.17-8.45 scores;Q4:8.46-10.95scores;Q5 ≥ 10.96 scores.Multivariate Logistic regression was used to analyze the association between cum BP level and new-onset CKD by cum BP exposure quintile grouping.Results The rise of cum BP exposure level caused the increased incidence of CKD.The incidences of CKD in the five quintile groups were 2.59％,3.11％,4.19％,5.81％,and 7.73％ respectively (P＜ 0.01).Compared with Q1 group,multivariate logistic regression analysis showed that after the adjustment of age,gender,education,income,smoking,drinking,BMI,FBG,TC,TG,LDL,HDL,UA and CRP,the incidences of CKD gradually increased in the Q2,Q3,Q4,and Q5 cum BP quintile groups,and OR(95％CI) values were 1.08(0.86-1.35),1.26(1.01-1.58),1.57(1.27-1.95),1.78(1.43-2.21) respectively (P for trend ＜0.01).Similar results were obtained in different genders.For each single point increase of cum BP exposure level,the incidence of CKD increased 6％ in the general population (P for trend ＜ 0.01),increased 8％ in male (P for trend ＜ 0.01),and 3％ in female (P for trend=0.12).Conclusion As the cumulative exposure to blood pressure increases,the risk of CKD incidence rises,especially in men.
