Associations between Depression, Stress, Anxiety, and Physical Activity Factors among Young Adults: A Secondary Analysis of the 2022 Korea National Health and Nutrition Examination Survey

Key Points

• This research aims to explore the associations between depression, stress, anxiety, and physical activity factors in young adults using a secondary analysis of survey data.
• Secondary analysis of data from the 2022 Korea National Health and Nutrition Examination Survey involving 1,193 adults aged 19-39.
• Correlational analysis to assess relationships between depression, perceived stress, anxiety, and physical activity.
• Hierarchical regression analysis to determine the explanatory power of sociodemographic, stress, and anxiety factors on depression.
• Depression significantly correlated positively with perceived stress (r=.456, p<.001) and anxiety (r=.630, p<.001).
• Moderate physical activity (r=−.104, p< .001) and walking days (r=−.080, p=.006) showed a negative correlation with depression.
• Hierarchical regression showed that sociodemographic variables explained 2.2% of the variance in depression, while adding stress and anxiety increased the explanation to 41.7% (ΔR²=.395, p<.001).
