PURPOSE: This study examined factors influencing subjective quality of life in baby boom generation men. METHODS: This was a descriptive survey study. Data were collected from 279 baby boom generation men from September to October 2012. The instruments used included a subjective quality of lifescale, a self-esteem scale, a spiritual well-being scale, a communication with spouse scale, a social support scale, and a job satisfaction scale. Data were analyzed using descriptive statistics, t-test, one-way ANOVA and Scheffe test, Pearson's correlation coefficients, and Hierarchical multiple regression. RESULTS: All variables were positively correlated with subjective quality of life. As a result, factors influencing subjective life of quality were self-esteem (beta=.21, p<.000), social support (beta=.20, p<.002), job satisfaction (beta=.19, p<.001), communication with spouse (beta=.15, p<.004), spiritual well-being(beta=.16, p<.004), and family income (beta=.15. p<.023). These factors accounted for 61% of the total variances. CONCLUSION: The findings indicate a need to develop nursing intervention programs for community health nurses in consideration of these variables to improve the subjective quality of life for baby boom generation men.
