Methods: We followed the occurrence of new care-needs certification for 3 years in 443 subjects who participated in the health examination and in the 395 non-participants we were able to interview during home visits (838 total subjects). Results: A total of 443 subjects participated in the examination. Home visiting for 449 older adults (of 904 non-participants) living in 8 of 16 districts in the village were conducted. We followed the occurrence of new care-needs certification for 3 years in 443 subjects who participated in the health examination and in the 395 non-participants we were able to interview during home visits (838 total subjects). Among the 838 subjects, there were 94 new certifications (11.2%) during the observation period. Starting in the second year, the occurrence rate of new care-needs certifications for non-participants was significantly higher than that of participants. The rate of care-needs certification over 3 years was significantly higher for non-participants (63/395, 16.0%) than for participants (31/443, 7.0%). Conclusion: Non-participants have a higher risk of care-needs certification. Projects aimed at understanding older adults are often performed during health examinations; however, it is necessary to investigate current data gathering methods for elderly patients who do not undergo these examinations.
