Survey on Korean People’s Health Behavior and Eating Habits according to Food Security Level

This study, conducted from 2019 to 2021 as part of the National Health and Nutrition Examination Survey, targeted a cohort of 17,817 participants. The primary objective was to discern factors influencing food security levels. According to the research findings, an escalation in food insecurity was associated with an increase in average age and a decrease in educational attainment, impacting both occupational choices and educational opportunities. Additionally, individuals experiencing food insecurity reported various health issues, such as physical discomfort and inadequate access to medical services, with these problems showing correlations with economic factors and an increased incidence of conditions like hypertriglyceridemia. Moreover, the study revealed significant associations between food insecurity and mental health, evidenced by heightened stress levels, consecutive depressive symptoms, and contemplation of suicide. In the exploration of physical activity and body composition characteristics, heightened food insecurity correlated with an expanded waist circumference and reduced physical activity, highlighting a prioritization of nutritional intake over exercise among this demographic. Regarding dietary habits, the study noted a diminishing trend in the frequency of dining out as food insecurity intensified. In conclusion, this research underscores the necessity for comprehensive public health programs tailored to individuals with lower food security levels, considering economic conditions and dietary habits.
