Abstract

Aim: The aim of the study was to evaluate the correlation between salivary and serum cortisol levels in the healthy population.

Methods: 30 healthy women and men, aged from 22 to 53 years old, were included in our study. All the participants were healthy, without any known disease. Two samples of salivary and serum cortisol were collected from all the participants in the study, in the morning and in the afternoon, before and after work. The mean age was 33 ± 14 SD years old. 60% (18) were females and 40% (12) were males. All the participants were within normal weight range, the mean BMI was 23.5 kg/m². All the subjects followed the rules of salivary sample collection.

Results: The mean age of the healthy subjects was 33 ± 14 years old. The mean baseline morning cortisol level of the study population was 159.6 ng/ml (SD: 41.7; normal range 55-230 ng/ml, 8:00 AM) and the mean salivary cortisol level in the morning was 3.2 µg/dL (SD: 2.4µg/dL; normal range 1-11.3 µg/dL). After work, at 4:00 PM, the mean baseline serum cortisol was 100.1 ng/ml (SD: 30.7; normal range 28-140 ng/ml) and the mean salivary cortisol level after work was 1.21 µg/dl (SD: 0.59; normal range 0.2-2.7 µg/dl). Baseline salivary cortisol correlated significantly with serum salivary cortisol before and after work; at 8:00 AM and 4:00
PM; p <0.05 in the morning and p< 0.0001 after work. The Pearson’s coefficients were 0.44 in the morning and 0.7 in the afternoon.

Conclusions: In our study we found a correlation between salivary and serum cortisol levels in both samples, in the morning and in the afternoon. The salivary cortisol levels correlated significantly with the serum cortisol levels (r = 0.44, p< 0.05 in the morning and r = 0.7, p<0.00.1 in the afternoon).
