In this study, we investigated the proportions of specific health guidance interventions and metabolic syndrome assessments during health check-ups from 2009 to 2020. The number of specific health guidance interventions has been increasing since 2017, while there is a declining trend in metabolic syndrome assessments. However, the proportion of follow-up observations and related activities remains at a high level. Moving forward, there is a clear need for widespread improvement in health awareness and lifestyle modification strategies.
