Size of study:
154 middle to older aged adults
Summary
Age was more strongly associated with telomere length for those subjects that scored poor on sleep quality using the Pittsburgh Sleep Quality Index. However, age was less strongly associated with telomere length for those subjects that reported good sleep quality per the PSQI. This study suggests that good sleep quality may attenuate some of the telomere attrition associated with advancing age.
