To prospectively examine the association of high sensitivity C-reactive protein (hs-CRP) with incident type 2 diabetes mellitus (T2DM) among middle-aged and elderly Chinese, and validate the association in an updated meta-analysis of prospective studies.
We used data from the China Health and Retirement Longitudinal Study, started in 2011-2012 with follow ups in 2013-2014 and 2015-2016. Multivariable Cox proportional hazard regressions were applied to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between hs-CRP level and incident T2DM. An updated meta-analysis was conducted to combine our estimates with those in previous prospective studies.
Included in the analyses were 7985 participants (mean age: 59.38 years; men: 46.73%). Higher hs-CRP was associated with increased risk of T2DM (multivariable-adjusted HR, 1.30; 95% CI: 1.03, 1.64 for comparing extreme quartiles). The association was stronger in participants with body mass index (BMI) of 24.0 kg/m or higher than those with a BMI lower than 24.0 kg/m (p for interaction = 0.038). In a meta-analysis of 28 cohorts, 2 case-cohort, and 6 nested case-control studies among 125,356 participants with 10,759 cases, the pooled relative risk for T2DM was 1.77 (95% CI: 1.60, 1.96) for the highest versus lowest level of hs-CRP.
Hs-CRP was associated with higher risk of T2DM in middle-aged and elderly Chinese, and this association was confirmed by an updated meta-analysis of prospective studies. Our findings highlight the role of elevated hs-CRP in the development of T2DM.
前瞻性研究高敏C反应蛋白（hs-CRP）与中国中老年人群2型糖尿病（T2DM）发病之间的关联，并在前瞻性研究的更新荟萃分析中验证该关联。
我们使用了中国健康与养老追踪调查（China Health and Retirement Longitudinal Study）的数据，该调查于2011 - 2012年启动，并在2013 - 2014年和2015 - 2016年进行了随访。采用多变量Cox比例风险回归来估计hs-CRP水平与T2DM发病之间关联的风险比（HRs）和95%置信区间（CIs）。进行了一项更新的荟萃分析，将我们的估计值与先前前瞻性研究中的估计值相结合。
纳入分析的有7985名参与者（平均年龄：59.38岁；男性：46.73%）。较高的hs-CRP与T2DM风险增加相关（多变量调整后的HR为1.30；比较极端四分位数时的95% CI：1.03，1.64）。在体重指数（BMI）≥24.0 kg/m²的参与者中，这种关联比BMI<24.0 kg/m²的参与者更强（交互作用p = 0.038）。在一项针对125356名参与者（其中10759例病例）的28个队列、2个病例队列和6个巢式病例对照研究的荟萃分析中，hs-CRP最高水平与最低水平相比，T2DM的合并相对风险为1.77（95% CI：1.60，1.96）。
hs-CRP与中国中老年人群患T2DM的较高风险相关，并且前瞻性研究的更新荟萃分析证实了这种关联。我们的研究结果突出了hs-CRP升高在T2DM发生发展中的作用。
