Study summary

Quality of life (QoL) is an important factor for successful aging. Telomere length is an indicator of cellular aging and cumulative biological stress and is thus related to health status and survival. However, the relationship between QoL and telomere length has not yet been examined. In this study we investigated the relationship between leukocyte telomere length (LTL) and QoL.

However, the relationship between overall QoL and LTL has not previously been investigated. Therefore, this study was conducted to examine the relationship between LTL and QoL. QoL was measured by the Korean version of the 36-item short-form health survey (SF-36), which is a multidimensional scale consisting of subjective evaluation.
