To investigate the prevalence of GAD antibody (GADA) in the general adult population and to evaluate its predictive value for diabetes in China.
We searched the PUMCH-HM database and identified 36,731 adult subjects with GADA test results from 2012 to 2015. We then established a retrospective cohort of 4835 nondiabetic subjects at baseline with complete annual health evaluation records through 2019. The median follow-up time was 4.8 (3.0-7.3) years.
The overall prevalence of GADA was 0.53% and was higher in diabetic subjects (1.25%) than in nondiabetic subjects (0.47%). We found a decrease in baseline body mass index (BMI) from the GADA- to GADA subgroups among baseline diabetic and prediabetic patients and also those who developed diabetes later in the cohort study. A total of 136 subjects (2.8%) developed diabetes after a median follow-up of 3.5 years. For GADA participants, BMI was not associated with the risk for diabetes. In the Cox regression model, the GADA and GADA exhibited 2.63-fold and 4.16-fold increased risk for diabetes, respectively. This increased risk for diabetes by GADA-positivity is only found in male adults (HR 4.55, 95% CI 2.25-9.23).
GADA has a low prevalence in China but is associated with a 2.63-4.16-fold increased risk for diabetes.
调查中国普通成年人群中谷氨酸脱羧酶抗体(GADA)的患病率,并评估其对糖尿病的预测价值。
我们检索了北京协和医院健康管理数据库,确定了2012年至2015年有GADA检测结果的36731名成年受试者。然后,我们建立了一个回顾性队列,其中包括4835名基线时非糖尿病受试者,他们拥有截至2019年的完整年度健康评估记录。中位随访时间为4.8(3.0 - 7.3)年。
GADA的总体患病率为0.53%,糖尿病患者中的患病率(1.25%)高于非糖尿病患者(0.47%)。我们发现,在基线糖尿病患者、糖尿病前期患者以及队列研究中后来患糖尿病的患者中,从GADA - 到GADA亚组,基线体重指数(BMI)有所下降。共有136名受试者(2.8%)在中位随访3.5年后患糖尿病。对于GADA参与者,BMI与糖尿病风险无关。在Cox回归模型中,GADA和GADA患糖尿病的风险分别增加了2.63倍和4.16倍。这种因GADA阳性导致的糖尿病风险增加仅在成年男性中发现(HR 4.55,95% CI 2.25 - 9.23)。
GADA在中国患病率较低,但与糖尿病风险增加2.63 - 4.16倍相关。
