Mindfulness and laboratory eating behavior in adolescent girls at risk for type 2 diabetes.

ABSTRACT: Mindfulness-based intervention has become increasingly popular to address disinhibited eating in obesity and type 2 diabetes (T2D). Theoretically, present-moment attention promotes the ability to recognize and respond to internal hunger cues and to differentiate physiological hunger from other stimuli. Yet, there is limited research describing the relationship of mindfulness with disinhibited eating patterns in adolescents. In this study, we evaluated the relationship of dispositional mindfulness to laboratory eating in 107 adolescent (12-17 years) girls at risk for T2D. Adolescents reported dispositional mindfulness, were evaluated for recent loss-of-control-eating (LOC-eating) by interview, and participated in two successive, standardized laboratory test meals to assess eating when hungry as well as eating in the absence of hunger (EAH). Adolescents rated state appetite throughout the test meal paradigms. In analyses adjusting for body composition and other possible confounds, mindfulness was inversely related to caloric intake during the EAH paradigm. Mindfulness did not relate to energy intake when hungry. Instead, there was a significant interaction of reported LOC-eating by state hunger, such that girls with recent, reported LOC-eating and high state hunger consumed more calories when hungry, regardless of mindfulness. Findings suggest that in girls at risk for T2D, mindfulness may play a role in disinhibited eating. A propensity for LOC-eating may be most salient for overeating in a high hunger state.

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:ImportanceInfections are recognized as playing a critical role in the risk of psychiatric disorders and suicidal behavior; however, few studies have evaluated the risk of eating disorders.ObjectiveTo evaluate the association of hospitalization for infections and treatment with anti-infective agents with the risk of an eating disorder diagnosis.Design, setting, and participantsA nationwide, population-based, prospective cohort study of 525 643 girls born from January 1, 1989, to December 31, 2006, and followed up until December 31, 2012, was conducted using individual-level data drawn from Danish longitudinal registers. Data were analyzed from January 15 to June 15, 2018, using survival analysis models and adjusted for age, calendar period, parental educational level, and parental history of psychiatric illness.ExposuresHospital admission for infections and prescribed anti-infective agents for infections.Main outcomes and measuresThe main outcome of interest was diagnosis of an eating disorder (anorexia nervosa, bulimia nervosa, or eating disorder not otherwise specified) in a hospital, outpatient clinic, or emergency department setting. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and accompanying 95% CIs.ResultsThe study population consisted of 525 643 adolescent girls: 2131 received a diagnosis of anorexia nervosa (median [range] age, 15.2 [8.6-21.3] years), 711 received a diagnosis of bulimia nervosa (median [range] age, 17.9 [13.4-22.7] years), and 1398 received a diagnosis of an eating disorder not otherwise specified (median [range] age, 15.6 [8.6-21.6] years). A total of 525 643 adolescent girls were followed up for 4 601 720.4 person-years until a mean age of 16.2 years (range, 10.5-22.7 years). Severe infections that required hospitalization were associated with an increased risk of a subsequent diagnosis of anorexia nervosa by 22% (HR, 1.22; 95% CI, 1.10-1.35), bulimia nervosa by 35% (HR, 1.35; 95% CI, 1.13-1.60), and eating disorder not otherwise specified by 39% (HR, 1.39; 95% CI, 1.23-1.57) compared with adolescent girls without hospitalizations for infections. Infections treated with anti-infective agents were associated with an increased risk of a subsequent diagnosis of anorexia nervosa by 23% (HR, 1.23; 95% CI, 1.10-1.37), bulimia nervosa by 63% (HR, 1.63; 95% CI, 1.32-2.02), and eating disorder not otherwise specified by 45% (HR, 1.45; 95% CI, 1.25-1.67) compared with adolescent girls without infections treated with anti-infective agents.Conclusions and relevanceThe findings suggest that hospital-treated infections and less severe infections treated with anti-infective agents are associated with increased risk of subsequent anorexia nervosa, bulimia nervosa, and eating disorders not otherwise specified and that future studies should investigate whether these associations are causal and identify the exact mechanisms between infections and subsequent inflammatory processes with eating disorders.
