The purpose of this study was to examine the effect of social capital on the mental stress, and to
examine the effect of social factors on stress. Ultimately, the empirical demonstration of the importance of
social factors is used to examine the effects of physical health on mental stress and to find out that stress
can be differentiated by social factors through the moderating effects of social capital. A total of 6,665
people were analyzed using the National Health and Nutrition Survey data. As a result, the physical health
was relatively good and the stress level was normal. Also, it was found that the lower the age, the lower
the recipient, the lower the health condition, the higher the stress level. Physical health and social capital
have a significant effect on stress, and social capital has a moderating effect on the effect of physical
health on stress. Based on these results, it was suggested that the amount and quality of social capital such
as informal resource network should be expanded as a strategy to mitigate stress.
