Purpose: This study aims to investigate the association of lifestyle values with lifestyle and quality of life among community-dwelling late middle-aged and older adults. Methods: This retrospective cross-sectional study analyzed secondary data of 200 late middle-aged and older adults. Lifestyle and lifestyle values were measured by Yonsei Lifestyle Profile (YLP) and YLP-Value, respectively. The mediator was quality of life, and a mediation analysis was conducted to examine the relationship between lifestyle values, lifestyle, and quality of life. Our study then repeated the analysis by dividing lifestyle into three components: physical activity, nutrition/eating habit, and activity participation. Results: Mediation analysis revealed significant associations across all pathways (all p<.001). The lifestyle values were associated with lifestyle (β=.40). Both lifestyle value (β=.40) and lifestyle (β=.18) were positively associated with quality of life. The indirect effect of lifestyle values on quality of life, mediated by lifestyle, accounted for 14.58% of the total effect, with the direct effect constituting 85.42%. Conclusion: Among the three components of lifestyle, a mediation effect was observed between lifestyle values, nutrition/eating habit, and quality of life. Our results indicate the need for education to increase lifestyle values within lifestyle programs, emphasizing the significance of lifestyle values in enhancing both lifestyle and quality of life among late middle-aged and older adults. Health professionals may integrate the results into interventions by recognizing the importance of lifestyle values.
