      Examinees (HEXA) Study.

AB  - OBJECTIVES: Self-reported disease history is often used in epidemiological 
      studies. In this study, we acquired the hospital records of subjects who 
      self-reported stroke or myocardial infarction (MI) and evaluated the validity of 
      the participants' self-reported disease history. We also determined the level of 
      agreement between specialists and non-specialists. METHODS: Among the 
      participants in the Health Examinees study, 1488 subjects self-reported stroke or 
      MI during 2012-2017, and medical records were acquired for the 429 subjects 
      (28.8%) who agreed to share their medical information. Each record was 
      independently assigned to 2 medical doctors for review. The records were 
      classified as 'definite,' 'possible,' or 'not' stroke or MI. If the doctors did 
      not agree, a third doctor made the final decision. The positive predictive value 
      (PPV) of self-reporting was calculated with the doctors' review as the gold 
      standard. Kappa statistics were used to compare the results between general 
      doctors and neurologists or cardiologists. RESULTS: Medical records from 208 
      patients with self-reported stroke and 221 patients with self-reported MI were 
      reviewed. The PPV of self-reported disease history was 51.4% for stroke and 32.6% 
      for MI. If cases classified as 'possible' were counted as positive diagnoses, the 
      PPV was 59.1% for stroke and 33.5% for MI. Kappa statistics showed moderate 
      levels of agreement between specialists and non-specialists for both stroke and 
      MI. CONCLUSIONS: The validity of self-reported disease was lower than expected, 
      especially in those who reported having been diagnosed with MI. Proper 
      consideration is needed when using these self-reported data in further studies.
