Another strength of our study is the sample size. In addition, more than 5000 participants received a geriatric consultation. Nevertheless, our study could feature an underreporting of some diseases/conditions because of the self-administered questionnaires. Moreover, to assess the multimorbidity measure, we did not use a validated instrument such as the Cumulative Illness Rating Scale  or the Duke Severity Illness Checklist , both of which cannot be used for an existing cohort. Finally, we did not assess the severity of conditions and did not use an exhaustive list of conditions.
