To quantify inconsistent self-reporting of chronic conditions between the baseline (2011-2015) and first follow-up surveys (2015-2018) in the Canadian Longitudinal Study on Aging (CLSA), and to explore methods to resolve inconsistent responses and impact on multimorbidity.
Community-dwelling adults aged 45-85 years in the baseline and first follow-up surveys were included ( = 45,184). At each survey, participants self-reported whether they ever had a physician diagnosis of 35 chronic conditions. Identifiable inconsistent responses were enumerated.
32-40% of participants had at least one inconsistent response across all conditions. Illness-related information (e.g., taking medication) resolved most inconsistent responses (>93%) while computer-assisted software asking participants to confirm their inconsistent disease status resolved ≤53%. Using these adjudication methods, multimorbidity prevalence at follow-up increased by ≤1.6% compared to the prevalence without resolving inconsistent responses.
Inconsistent self-reporting of chronic conditions is common but may not substantially affect multimorbidity prevalence. Future research should validate methods to resolve inconsistencies.
在加拿大老龄化纵向研究（CLSA）中，量化基线（2011-2015 年）和第一次随访调查（2015-2018 年）之间慢性疾病自我报告的不一致，并探讨解决不一致反应的方法及其对多种慢性疾病的影响。
本研究纳入了基线和第一次随访调查中年龄在 45-85 岁的社区居住成年人（n=45184）。在每一次调查中，参与者自我报告是否曾被医生诊断出患有 35 种慢性疾病。对可识别的不一致反应进行了计数。
所有疾病中，有 32-40%的参与者至少有一次不一致的反应。与疾病相关的信息（例如，正在服用药物）解决了大多数不一致的反应（>93%），而计算机辅助软件要求参与者确认其不一致的疾病状态仅解决了≤53%的反应。与不解决不一致反应相比，使用这些裁决方法，随访时多种慢性疾病的患病率增加了≤1.6%。
慢性疾病自我报告的不一致很常见，但可能不会对多种慢性疾病的患病率产生实质性影响。未来的研究应验证解决不一致反应的方法。
