Table 6.

Rate of change in two stress biomarkers per hour due to underlying circadian rhythm (diurnal effect) and activity types; based on model outcomes for cortisol in Table 5 (NE = 110) and for amylase in Table 4, Model 2 (NE = 103).

Effect Model beta % Cortisol change/hour Model beta % Amylase change/hour
Diurnal effect –0.124 –11.7% +0.034 +3.5%
NE duration while sitting or sitting + walking –0.240 –21.3% –0.33 –28.1%
NE duration while walking only –0.239 –21.3% –0.04 –3.9%

For negative slopes, % drop is calculated as (1 – e beta estimate); for positive slopes, % rise is calculated as (e beta estimate – 1).
