Mindfulness-Based Program Embedded Within the Existing Curriculum Improves Executive Functioning and Behavior in Young Children: A Waitlist Controlled Trial.

There is a growing evidence base for mindfulness-based interventions in educational settings. Notably, there has been little investigation of the potential benefits of classroom-based mindfulness programs in children in the early school years (Preparatory/Kindergarten, Grades 1 and 2) despite early childhood being a period characterized by the development of self-regulation and executive functions. The present study investigated the effects of a mindfulness program that was embedded within a school curriculum. This waitlist controlled trial investigated the effects of a mindfulness program, CalmSpace, delivered by classroom teachers across two school terms. A total of 55 students, M age = 76.4 months, SD = 8.62, were allocated to participate in CalmSpace in Terms 3 and 4. Thirty-six students in the waitlist control condition, M age = 80.53 months, SD = 13.04, participated in the intervention in Term 4. The start of Term 3 served as baseline (Time 1), and measures were obtained at the end of Term 3 (Time 2) and the end of Term 4 (Time 3). Direct measures of executive functioning using the Flanker Inhibitory Control and Attention Test (Flanker Task) and Dimensional Change Card Sort Task (DCCS) from the National Institute of Health Toolkit were obtained. Teachers' report of children's behavior was also obtained using the Strengths and Difficulties Questionnaire (Teacher version) at the beginning and at the end of Term 3, and at the end of Term 4. Children who received the CalmSpace program showed improvements on the DCCS relative to waitlist control at Time 2 (Cohen's d = 0.48) and Time 3 (Cohen's d = 1.10). Similar results were found on the Flanker Task with greater improvements found at Time 2 (Cohen's d = 0.77) and Time 3 (Cohen's d = 1.33). Teachers reported improvements for those receiving CalmSpace at Time 2 on total SDQ scores, Emotional Symptoms, Conduct Problems, Hyperactivity/Attention (Cohen's d = 0.32, 0.14, 0.46, 0.30, 0.33, and 0.53, respectively) compared to waitlist control and at Time 3 (Cohen's d = 0.85, 0.37, 0.48, and 0.90, respectively). The findings demonstrate that implementing the CalmSpace program can lead to improvements in EF and attention for young children. Despite limitations, this study provides promising evidence that the inclusion of focused, targeted mindfulness activities throughout the day may represent a value-added component to the regular school curriculum that can result in benefits for the students.

Adverse Health Outcomes in Offspring Associated With Fetal Alcohol Exposure: A Systematic Review of Clinical and Preclinical Studies With a Focus on Metabolic and Body Composition Outcomes.

Prenatal alcohol exposure (PAE) results in well-characterized neurological, behavioral, and cognitive deficits in offspring. However, the effects on other health outcomes have not been comprehensively described. We used a systematic review methodology to survey published clinical and preclinical studies investigating a broad range of health outcomes in offspring with PAE. This study specifically reports on outcomes related to metabolism and body composition. The literature was systematically searched across 4 electronic databases (PubMed, CINAHL, Embase, and Web of Science), resulting in 3,230 articles following duplicate removal. Titles and abstracts were reviewed against specific inclusion/exclusion criteria, with 242 articles meeting the criteria for full-text assessment of eligibility. Articles with ineligible study type were removed (127) and articles added from reference lists (15) and an updated search closer to submission (9) for a total of 139 studies. Although 5 health domains were identified, here we focus on metabolism and body composition. Details of alcohol exposure, offspring demographics, and sample sizes were tabulated and quality of reporting assessed. Findings were summarized for body composition (percentage fat mass), physiological and molecular outcomes related to glucose metabolism, and outcomes related to lipid metabolism. There were 32 included studies (2 case-control, 1 prospective longitudinal cohort, and 29 preclinical). Studies had a range of alcohol exposures, both dosage and timing, although all clinical studies had heavy PAE and/or evidence of fetal alcohol syndrome in offspring. The preclinical studies provided evidence of glucose intolerance and/or insulin resistance; dyslipidemia and/or hypercholesterolemia; and increased adiposity in offspring with PAE. Due to the paucity of clinical studies, we recommend further studies be conducted to obtain a complete assessment of long-term metabolic health outcomes in children and adults with PAE, particularly in those diagnosed with fetal alcohol spectrum disorder.

Physiological self-regulation and mindfulness in children with a diagnosis of fetal alcohol spectrum disorder.

OBJECTIVE: To explore the differences in baseline respiratory sinus arrhythmia (RSA) between children with fetal alcohol spectrum disorder (FASD) and typically developing children (TDC) and to investigate whether children with FASD have the capacity to engage in a brief mindfulness exercise. METHODS: Participants were 14 children with FASD and 20 TDC. RSA was measured at baseline, during, and following a mindfulness exercise. A mindfulness compliance checklist was completed to ascertain if children could follow the task instructions. RESULTS: Both groups obtained high scores on the mindfulness compliance checklist. There was a trend for children with FASD to have lower baseline RSA compared to TDC. Children in both groups demonstrated an increase in RSA during the mindfulness task. CONCLUSIONS: Children with FASD could engage in a mindfulness task, and both groups showed an increase in RSA. Further research is needed to establish whether prolonged mindfulness practice could be beneficial.
