Relationship of Mindfulness to Distress and Cortisol Response in Adolescent Girls At-Risk for Type 2 Diabetes.

ABSTRACT: Altered stress response theoretically contributes to the etiology of cardiometabolic disease. Mindfulness may be a protective buffer against the effects of stress on health outcomes by altering how individuals evaluate and respond to stress. We engaged adolescent girls at risk for developing Type 2 diabetes in a cold-pressor test in order to determine the relationship of dispositional mindfulness to cortisol response and subjective stress, including perceived pain and unpleasantness during the stressor, and negative affect following the stressor. We also evaluated mindfulness as a moderator of psychological distress (depressive/anxiety symptoms) and stress response. Participants were 119 girls age 12-17 years with overweight/obesity, family history of diabetes, and mild-to-moderate depressive symptoms. Greater mindfulness was associated with less perceived pain and negative affect, but was unrelated to cortisol response to the stressor. Regardless of mindfulness, greater depressive/anxiety symptoms related to a more blunted cortisol response. Mindfulness might promote better distress tolerance in adolescents at risk for diabetes by altering how youth perceive and relate to acute stress, rather than through altering the physiological stress response. At all levels of mindfulness, depressive/anxiety symptoms relate to greater blunting of cortisol response. Findings contribute to emerging literature on the role of mindfulness in promoting the mental and physical health and well-being of individuals at risk for Type 2 diabetes.

Project description:OBJECTIVE:(1) Evaluate feasibility and acceptability of a mindfulness-based group in adolescent girls at-risk for type 2 diabetes (T2D) with depressive symptoms, and (2) compare efficacy of a mindfulness-based versus cognitive-behavioral group for decreasing depressive symptoms and improving insulin resistance. DESIGN AND SETTING:Parallel-group, randomized controlled pilot trial conducted at a university. PARTICIPANTS:Thirty-three girls 12-17y with overweight/obesity, family history of diabetes, and elevated depressive symptoms were randomized to a six-week mindfulness-based (n=17) or cognitive-behavioral program (n=16). INTERVENTIONS:Both interventions included six, one-hour weekly group sessions. The mindfulness-based program included guided mindfulness awareness practices. The cognitive-behavioral program involved cognitive restructuring and behavioral activation. MAIN OUTCOME MEASURES:Adolescents were evaluated at baseline, post-intervention, and six-months. Feasibility/acceptability were measured by attendance and program ratings. Depressive symptoms were assessed by validated survey. Insulin resistance was determined from fasting insulin and glucose, and dual energy x-ray absorptiometry was used to assess body composition. RESULTS:Most adolescents attended ?80% sessions (mindfulness: 92% versus cognitive-behavioral: 87%, p=1.00). Acceptability ratings were strong. At post-treatment and six-months, adolescents in the mindfulness condition had greater decreases in depressive symptoms than adolescents in the cognitive-behavioral condition (ps<.05). Compared to the cognitive-behavioral condition, adolescents in the mindfulness-based intervention also had greater decreases in insulin resistance and fasting insulin at post-treatment, adjusting for fat mass and other covariates (ps<.05). CONCLUSIONS:A mindfulness-based intervention shows feasibility and acceptability in girls at-risk for T2D with depressive symptoms. Compared to a cognitive-behavioral program, after the intervention, adolescents who received mindfulness showed greater reductions in depressive symptoms and better insulin resistance.

Project description:Abnormal hypothalamic-pituitary-adrenal (HPA) axis function, as indexed by elevated diurnal cortisol levels and/or a blunted cortisol awakening response (CAR), has been observed among patients with first episode psychosis and associated with neurocognitive deficits in this population. However, the extent to which these features precede illness onset is unclear. The current study aimed to determine whether children who are at putatively elevated risk for psychosis because they present multiple antecedents of schizophrenia (ASz), and high-risk children with a family history of illness (FHx), are characterized by abnormal cortisol levels when compared with their typically developing (TD) peers. A further aim was to investigate the extent to which cortisol levels are associated with psychosocial stress and neurocognitive function. Thirty-three ASz children, 22 FHx children, and 40 TD children were identified at age 9-12 years using a novel community-based screening procedure or as relatives of individuals with schizophrenia. All participants were antipsychotic-naive and not currently seeking treatment for their symptoms. At age 11-14 years, participants provided salivary cortisol samples and completed psychosocial stress measures and tests of memory and executive function. Results indicated that FHx children, but not ASz children, were characterized by a blunted CAR relative to their TD peers (effect size=-0.73, p=0.01) that was not explained by psychosocial stress exposure or by distress relating to these experiences. Neither FHx nor ASz children were characterized by elevated diurnal cortisol. Among both FHx and ASz children, more pronounced HPA axis function abnormalities (i.e., higher diurnal cortisol levels and greater blunting of the CAR) were associated with poorer performance on tests of verbal memory and executive function. These findings support the notion that at least some HPA axis abnormalities described in psychosis precede illness onset, rather than being a subsequent epiphenomenon. We speculate that the blunted CAR may constitute an early (potentially genetically mediated) marker of psychosis vulnerability, whilst elevated diurnal cortisol levels may emerge only proximally to disease onset.
