Abstract
OBJECTIVE
Depression is a widespread mental health issue, often coexisting with physical conditions. Understanding its interplay with physical illnesses is crucial for holistic care.
METHODS
We analyzed the pooled data from three cross-sectional surveys of the Korea National Health and Nutrition Examination Survey (KNHANES) conducted in 2016, 2018, and 2020. Data on depression and physical illness for participants aged 19 and above were collected based on information provided by the participants.
RESULTS
In cases where depression and physical illnesses occur independently, the diagnosed age for depression is typically earlier than that of physical health conditions. Furthermore, when exploring scenarios where depression coexists with physical illnesses, it is observed that depression often precedes the development of these conditions in most cases. However, exceptions to this trend are found in diabetes mellitus, thyroid disorders, and asthma, where the presence of these diseases is linked to an elevated risk of depression onset. Interestingly, the study also implies that the mood state associated with depression, rather than the diagnosis itself, may influence health-related behaviors, potentially playing a role in the development of physical illnesses.
CONCLUSION
Depression and physical illnesses share complex associations. Early detection, interventions, and addressing lifestyle factors are vital. This study's insights underscore the need for comprehensive mental and physical health care, though further research is needed for deeper understanding. The findings emphasize the importance of considering depression as a potential risk factor for physical illnesses and highlight the interplay between depression and physical health.
