Association of serum high-sensitivity C reactive protein with risk of mortality in an Asian population: the Health Examinees cohort

초록

Objectives This study aimed to examine the association of high-sensitivity C reactive protein (hsCRP) with mortality risk and the attenuated effect of non-communicable disease history (NCDhistory) on the association. Design Prospective cohort study. Setting Health Examinees cohort. Participants A total of 41 070 men and 81 011 women aged >= 40 years were involved (follow-up: 6.8 years). Outcome measures Data and cause of death occurring until 31 December 2015 were confirmed by death statistics from the National Statistical Office. We conducted advanced analysis after stratification by NCDhistory and sensitivity analysis after excluding death before 1 or 2 years from recruitment. Cox proportional hazard and restricted cubic spline models were used to assess the association. Results The association between serum hsCRP and risk of all-cause mortality was observed with strong linearity in both genders and was not influenced by NCDhistory. The association of serum hsCRP with risk of cancer mortality was not observed in women with NCDhistory, but the association with risk of cardiovascular disease (CVD) mortality was predominantly observed in men with NCDhistory. Conclusions This study suggests a dose-response association of hsCRP with mortality risk, including cancer and CVD mortality, in Koreans with low serum hsCRP, although the association with cancer and CVD mortality risk could be influenced by gender and NCDhistory.
