This study compared the awakening response and diurnal rhythm of cortisol in young versus older adults in relation to health behaviours. Older adults displayed significantly reduced cortisol upon awakening, a lower cortisol awakening response and a flatter diurnal profile represented by a reduced area under the curve and cortisol slope. There was also a significant interaction of age, cortisol and diet; younger adults with a higher fat and lower fruit and vegetable intake exhibited the flattened diurnal cortisol phenotype of the older adults.
