<sec>

<p>As aging is a process that everyone must experience, life expectancy is getting longer and living standards are getting better. But aging can be successful or unsuccessful. Middle-aged adults experience an existential crisis of physical burdens and middle-aged crises, thereby changing the quality of life in old age. The purpose of this study was to identify the factors affecting successful aging in middle-aged adults.</p>
</sec>
<sec>
<title>Methods</title>
<p>This is a cross sectional descriptive study design was used to examine the association among middle-age crisis, perceived health status, self-esteem, social support and successful aging in late middle-aged adults.</p>
</sec>
<sec>
<title>Results</title>
<p>Perceived health status and social support had a statistically significant effect on successful aging, and middle-aged crisis and self-esteem were not significant. The factors' determination value was 63.6%.</p>
</sec>
<sec>
<title>Conclusions</title>
<p>The perceived health status and social support of middle-aged adults may help the successful aging of middle-aged adults. Therefore, it is necessary to develop education for health promoting activities and social support programs with various materials.</p>
