Abstract:
Objective To explore the relationship between high sensitive C-reactive protein (hsCRP) and renal function among people aged 90 years and over in longevity regions in China.Methods Totally 506 subjects aged 90 years and over in 5 longevity areas from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) 2008-2009 were included in the study.Demographic,behavioral and lifestyle parameters and self-reported chronic diseases were collected by general health-related questionnaire.We conducted the physical examination and also measured serum hsCRP and other indicators of renal function.Logistic regression was used to analyze the relationship between hsCRP and renal function.Results The prevalence of elevated hsCRP was 36.6% in people aged 90 years and over,43.0% in male and 34.8% in female.No significant gender difference was observed among them (x2 =2.4184,P=0.1199).The prevalence of elevated hsCRP were 34.4% in 90-99 years group and 39.2% in the centenarian group,and there was no significant difference between the two groups (x2 =1.2425,P =0.2650).We found significant statistical difference in prevalence of elevated hsCRP between declined renal function group (42.0%) and normal group (33.3%) (t=3.8450,P=0.0499).The level of serum creatinine were (89.5±37.4) μmol/L in elevated hsCRP group and (81.5±31.4) μmol/L in the normal hsCRP group among the people aged 90 years and over.Significant difference was found between the elevated and normal hsCRP group (x23.8450,P=0.0161).In the multivariate logistic regression analysis,the risk factors of renal function decline were female,smoking,hypertension,hyperuricemia and elevated hsCRPCOR=1.676 (95%CI:1.091-2.573)].Conclusions Elevated hsCRP increases the risk of renal function decline among people aged 90 years and over in China.
