| Abstract/Results: | ABSTRACT:
Many studies have explored the relationship between cortisol secretion and state well-being or ill-being; however, results are inconsistent. This may be explained to some extent by participant non-adherence to the saliva sampling protocol particularly for studies investigating the cortisol awakening response (CAR) as delays (> 5 min) in collecting the first saliva sample lead to misleading measurements of the CAR. Another factor may be the age group of the participants. Consistent associations are found in middle-aged and older populations, whereas relatively weak relationships tend to be found in younger individuals. This study aimed to objectively monitor adherence to the saliva sampling protocol and investigate the relationship between well-being and the CAR and cortisol over the day in a young healthy female sample.
50 healthy female students collected saliva samples on four days at 0, 15, 30, and 45 minutes, 3 and 12 hours post-awakening. State wellbeing and ill-being was assessed by mood ratings throughout each sampling day. Participants rated the extent to which they felt pleased, happy, goal-directed, stressed, out of control, frustrated, and down using electronic devices. Participants were made aware that awakening and sampling times were objectively monitored.
Participants were relatively adherent to the saliva sampling protocol, delays of < 5 min (mean: 1±1 min) was achieved on the majority of sampling days (N=80). Days with delays of over 5 minutes (mean: 13±12 min) were excluded (N=73) from analyses involving the CAR. Mixed modelling showed there was no relationship between well-being or ill-being and the CAR, the diurnal decline and cortisol over the day.
The lack of an association between well-being or ill-being and cortisol on days where saliva samples were collected accurately supports the neurotoxicity hypothesis of HPA axis dysregulation. In young healthy individuals the HPA-axis is resilient and thus associations between well-being or ill-being and cortisol will be absent or weak. We would hypothesise that these associations would be stronger in participants with vulnerability as a result of early life stress (not measured in this study) and in older adults.
