Abstract
Chronic health conditions such as obesity, type II diabetes, cardiovascular disease,
depression and anxiety are prevalent among Māori women in New Zealand, as are
adverse experiences in childhood and chronic stress. Recent studies have shown a
link between adverse childhood experiences (ACEs) and chronic health problems
later in life. Many of those studies propose that dysregulation in the stress response
system - specifically the hypothalamic-pituitary-adrenal (HPA) axis - mediates that
link. Cortisol is the primary corticosteroid released by the HPA axis and is commonly
used as a biomarker for assessing HPA axis functioning. Mindfulness-Based Stress
Reduction (MBSR) is a therapy that uses a range of breathing techniques,
stretches, formal meditations and awareness exercises designed to help regulate
the stress response by changing the way the brain manages and relates to stress.
Due to its Eastern roots, MBSR therapy assumes an holistic view of health that
mirrors some of the key concepts promoted in Te Ao Māori. This research tested the
HPA axis functioning of eight adult Māori women who had experienced high ACEs,
and explored associations between cortisol dysregulation, visceral obesity (a risk
factor for many chronic health conditions) and psychological distress. This research
also tested the clinical effectiveness and cultural responsiveness of an MBSR
course that had been enhanced to suit a Māori audience. Participants provided pre,
mid and post-treatment salivary cortisol samples that measured changes to their
acute stress cortisol response, as well as changes to their daily cortisol slope, their
cortisol awakening response and their overall cortisol levels. They also provided pre
and post-treatment waist circumference measurements. Self-report data assessing
depression and anxiety levels, PTSD levels, stress eating habits, perceived stress
levels and mindful awareness levels, was collected, as was qualitative data in the
form of pre and post-treatment interviews. The results indicated that culturally
enhanced MBSR therapy was well received with this sample of Māori women and
that the participants reported a wide range of benefits as a result of practicing
mindfulness meditation.
