Few studies examined comorbid anxiety and depression’s independent association with dementia. We assessed internalizing disorders as risk factors for dementia to avoid pitfalls inherent in separating anxiety and depression. Retrospectively designed prospective comparative cohort study using New Zealand’s (NZ) National Minimum Dataset of hospital discharges. Hazards ratios (HRs), estimated from parametric survival models, compared the time to incident dementia after a minimal latency interval of 10 years between those with and without prior diagnosis of an internalizing disorder. A total of 47,932 patients aged 50–54 years were discharged from a publicly funded hospital events in NZ between 1988 and 1992. Of these, 37,631 (79%) met eligibility criteria, and incident dementia was diagnosed in 1594. Rates of incident dementia were higher among patients with an earlier diagnosis of internalizing disorders (572 vs 303 per 100,000 person years at risk (PYAR)). After adjustment for age, sex, ethnicity, and region, those with internalizing disorders were estimated to have a higher risk of developing dementia than those without (adjusted HR = 1.57, 95% CI 1.17–2.10). Females with an earlier diagnosis of internalizing disorders were estimated to have almost twice the risk of developing dementia (adjusted HR 1.80, 95% CI 1.25–2.59). Internalizing disorders affect one in five adults globally. Our findings suggest a significant increase in risk of dementia more than 10 years after the diagnosis of internalizing disorder.

内化自负:内化障碍作为痴呆的危险因素——队列研究

很少有研究检查共病焦虑和抑郁与痴呆症的独立关联。我们将内化障碍评估为痴呆的危险因素,以避免分离焦虑和抑郁所固有的陷阱。使用新西兰 (NZ) 国家最低出院数据集进行回顾性设计的前瞻性比较队列研究。从参数生存模型估计的风险比 (HRs) 比较了先前诊断为内化障碍的患者和未诊断为内化障碍的患者在 10 年的最小潜伏期后发生痴呆的时间。1988 年至 1992 年间,共有 47,932 名 50-54 岁的患者从新西兰的公共资助医院事件中出院。其中,37,631 人(79%)符合资格标准,1594 年被诊断为痴呆症。早期诊断为内化障碍的患者的痴呆发病率较高(572 对 303 每 100,000 人风险年 (PYAR))。在对年龄、性别、种族和地区进行调整后,估计患有内化障碍的人比没有内化障碍的人患痴呆症的风险更高(调整后的 HR = 1.57, 95% CI 1.17-2.10)。据估计,早期诊断为内化障碍的女性患痴呆症的风险几乎是其两倍(调整后的 HR 1.80,95% CI 1.25-2.59)。内化障碍影响全球五分之一的成年人。我们的研究结果表明,在诊断内化障碍 10 年后,患痴呆症的风险显着增加。性别、种族和地区,估计有内化障碍的人比没有内化障碍的人患痴呆症的风险更高(调整后的 HR = 1.57, 95% CI 1.17-2.10)。据估计,早期诊断为内化障碍的女性患痴呆症的风险几乎是其两倍(调整后的 HR 1.80,95% CI 1.25-2.59)。内化障碍影响全球五分之一的成年人。我们的研究结果表明,在诊断内化障碍 10 年后,患痴呆症的风险显着增加。性别、种族和地区,估计有内化障碍的人比没有内化障碍的人患痴呆症的风险更高(调整后的 HR = 1.57, 95% CI 1.17-2.10)。据估计,早期诊断为内化障碍的女性患痴呆症的风险几乎是其两倍(调整后的 HR 1.80,95% CI 1.25-2.59)。内化障碍影响全球五分之一的成年人。我们的研究结果表明,在诊断内化障碍 10 年后,患痴呆症的风险显着增加。据估计,早期诊断为内化障碍的女性患痴呆症的风险几乎是其两倍(调整后的 HR 1.80,95% CI 1.25-2.59)。内化障碍影响全球五分之一的成年人。我们的研究结果表明,在诊断内化障碍 10 年后,患痴呆症的风险显着增加。据估计,早期诊断为内化障碍的女性患痴呆症的风险几乎是其两倍(调整后的 HR 1.80,95% CI 1.25-2.59)。内化障碍影响全球五分之一的成年人。我们的研究结果表明,在诊断内化障碍 10 年后,患痴呆症的风险显着增加。
