JAMA:糖尿病发病年龄越小,患痴呆症的风险越高

2021-05-08 生物探索 生物探索

糖尿病发病年龄与痴呆风险的相关性。

糖尿病是血糖水平慢性升高为特征的代谢性疾病,主要包括1型糖尿病和2型糖尿病,其患病率和发病率一直居高不下。

由于人口老龄化、肥胖增加、缺乏运动和能量密集型饮食,2型糖尿病的流行率上升。超过90%的糖尿病患者患有2型糖尿病。目前研究已经表明糖尿病与更高的心血管疾病发病率和死亡率相关,大规模的多队列meta分析表明,糖尿病和痴呆之间的关联风险比在1.43 - 1.62之间。但其研究的主要局限性是不能检验糖尿病发病年龄对痴呆的重要性。

2021年4月27日,法国巴黎大学Archana Singh-Manoux团队在《美国医学会杂志》发表了研究成果,题为“Association Between Age at Diabetes Onset and Subsequent Risk of Dementia”,研究了糖尿病发病年龄与痴呆风险的相关性。

为了探讨糖尿病发病年龄越小是否与痴呆发病风险有更密切的关系,研究组在英国进行了一项基于人群的研究,这项研究名为Whitehall II研究,是一项持续进行的队列研究,建立于1985年至1988年,对象为伦敦的10308人(6895名男性和3413名女性,年龄在35-55岁)。

从基线开始,随访的临床检查大约每4 - 5年进行一次,每个周期需要2年完成,并在2020-2021年周期持续收集数据,并与电子健康记录挂钩。相关记录的数据每年更新一次,直至2019年3月31日。2型糖尿病,定义为临床检查时空腹血糖水平大于或等于126 mg/dL、医生诊断为2型糖尿病、使用糖尿病药物、或1985年至2019年期间的糖尿病住院记录。

2型糖尿病与痴呆发病率和糖尿病发病年龄之间的关系

10095名参与者中67.3%为男性,平均随访31.7年,研究组共记录了1710例糖尿病患者和639例痴呆患者。在70岁时无糖尿病的参与者中,每1000人-年的痴呆率为8.9;在5年前发病的参与者中,每1000人-年痴呆率为10.0;在6至10年前发病的参与者中,每1000人-年痴呆率为13.0;在10年前发病的参与者中,每1000人-年痴呆率为18.3。

55岁、60岁、65岁和70岁糖尿病风险评分与痴呆发病率的相关性

在多变量校正分析中,与70岁时无糖尿病的参与者相比,10年前患糖尿病患者痴呆的风险比为2.12,6-10年前患糖尿病患者痴呆的风险比为1.49,糖尿病发病时间少于5年的患者痴呆的风险比为1.11;线性趋势检验表明2型糖尿病发病年龄与痴呆之间存在分级关联。在对社会人口因素、健康行为和健康相关措施进行校正后的分析中,70岁时,2型糖尿病发病年龄每年轻5岁,痴呆的风险比为1.24。

心血管共病在糖尿病和痴呆发病率之间的关联中的作用

研究最后提到:目前的研究没有有力的证据表明糖尿病前期和痴呆之间存在联系。在正常范围内空腹血糖有可能对脑功能没有不利影响。无糖尿病者的空腹血糖与血管疾病的风险只有轻微的相关性。高糖水平的某一阈值对于高血糖诱导的脑损伤可能是必要的条件,所以考虑血管共病是否与糖尿病患者的痴呆发作有关是很重要的。

总之,在这项中位随访31.7年的纵向队列研究中,较年轻的糖尿病发病年龄与随后发生痴呆的较高风险显着相关。
