Pregnancy-specific stress and sensitive caregiving during the transition to motherhood in adolescents.

BACKGROUND: Maternal prenatal stress is associated with worse socio-emotional outcomes in offspring throughout childhood. However, the association between prenatal stress and later caregiving sensitivity is not well understood, despite the significant role that caregiving quality plays in child socio-emotional development. The goal of this study was to examine whether dimensions of pregnancy-specific stress are correlated with observer-based postnatal maternal caregiving sensitivity in pregnant adolescents. METHODS: Healthy, nulliparous pregnant adolescents (n = 244; 90 % LatinX) reported on their pregnancy-specific stress using the Revised Prenatal Distress Questionnaire (NuPDQ). Of these 244, 71 participated in a follow-up visit at 14 months postpartum. Videotaped observations of mother-child free play interactions at 14 months postpartum were coded for maternal warmth and contingent responsiveness. Confirmatory factor analysis of the NuPDQ supported a three-factor model of pregnancy-specific stress, with factors including stress about the social and economic context, baby's health, and physical symptoms of pregnancy. RESULTS: Greater pregnancy-specific stress about social and economic context and physical symptoms of pregnancy was associated with reduced maternal warmth but not contingent responsiveness. CONCLUSIONS: Heightened maternal stress about the social and economic context of the perinatal period and physical symptoms of pregnancy may already signal future difficulties in caregiving and provide an optimal opening for early parenting interventions.

Altered frontal interhemispheric and fronto-limbic structural connectivity in unmedicated adults with obsessive-compulsive disorder.

BACKGROUND: Previous diffusion tensor imaging (DTI) studies of obsessive-compulsive disorder (OCD) have primarily used voxel- or tract-based methods to assess white matter microstructure in medicated patients. This is the first probabilistic tractography study to assess the structural connectivity of all major white matter tracts in unmedicated adults with OCD without comorbid psychopathology. We hypothesized that OCD compared to healthy participants would show reduced integrity in frontal interhemispheric and fronto-limbic tracts. METHODS: DTI data from 29 unmedicated adults with OCD were compared to that of 27 matched healthy control (HC) participants. TRACULA was used to assess probabilistic tractography and compare groups in the average fractional anisotropy (FA) of 8 bilateral tracts plus forceps minor and major, and explore group differences in axial (AD), radial (RD), and mean (MD) diffusivities in tracts where FA differed across groups. RESULTS: Significantly less FA was detected in OCD compared to HC participants in forceps minor, interhemispheric fibers of the frontal cortex, and right uncinate fasciculus (UNC), association fibers connecting frontal and limbic regions (p's < .05). FA in forceps minor was inversely associated with symptom severity in the OCD participants. Exploratory analyses revealed less AD in right UNC was inversely associated with OCD symptoms. CONCLUSIONS: Structural connectivity of frontal interhemispheric and fronto-limbic circuits may be altered in unmedicated adults with OCD, especially those with the most severe symptoms. These findings suggest a microstructural basis for the abnormal function and reduced resting-state connectivity of frontal regions and fronto-limbic circuits in OCD.

Perspectives from clinicians and managers: facilitators and barriers to the uptake of rehabilitation guidance for children with arthrogryposis.

PURPOSE: To identify the perceived facilitators and barriers among clinicians and managers about the uptake of expert guidance for rehabilitation of children with arthrogryposis multiplex congenita (AMC) in practice. METHODS: Qualitative study using individual interviews, guided by the Theoretical Domains Framework (TDF), to explore beliefs and to identify facilitators and barriers to guidance uptake. Interviews were conducted with a convenience sample of 15 clinicians working with children with AMC and four pediatric clinical managers using Microsoft Teams©. Interviews were then transcribed verbatim and analyzed by four independent reviewers using deductive and inductive coding. RESULTS: The TDF domains of Environmental Context and Resources, Behavioural Regulation, Reinforcement, Beliefs about Consequences, and Social Influences were shared amongst clinicians and clinical managers across North America and Europe as being relevant and influential on the target behaviour of using rehabilitation expert guidance to manage pediatric patients. Among clinicians only, the domain Memory, Attention, and Decision-Making Processes was also found relevant. Among managers only, the domain Social/Professional Role and Identity was found relevant. CONCLUSIONS: Coupling shared relevant domains amongst clinicians and managers with individual supports and barriers helps to map out what is needed to promote the uptake of rehabilitation guidance at multiple levels.

The uptake of expert guidance is helpful for rehabilitation professionals to align best practice with expert opinion based on clinicians and lived experience for a condition as rare as arthrogryposis multiplex congenita (AMC).In order to facilitate the uptake of guidance, rehabilitation professionals and clinical managers need to collaborate during the development and uptake in practice.Rehabilitation professionals require support for the uptake of guidance, such as training, regular team encounters, and a knowledge broker.Rehabilitation professionals and clinical managers should be aware of identified facilitators and barriers to the uptake of guidance, such as time, clinical resources, and accessibility.

Assessment and Treatment of Anxiety Among Children and Adolescents.

Among children and adolescents, anxiety disorders are common psychiatric disorders that confer risk of comorbid psychiatric disorders and social and academic impairment. This review focuses on the assessment and treatment of anxiety disorders among children and adolescents, with attention to separation anxiety disorder, social phobia disorder (social anxiety disorder), panic disorder, and generalized anxiety disorder. Comprehensive assessment of child and adolescent anxiety disorders benefits from a multimethod approach to evaluation and diagnosis, including semistructured interviews; child and informant questionnaires; collateral information from parents, teachers, pediatricians, and school psychologists; and behavioral observations. Because anxiety symptoms can include avoidance behaviors, somatic complaints, social difficulties, and sleep disturbances, consideration of a differential diagnosis is important. Among the available psychosocial interventions, cognitive-behavioral therapy (CBT) and exposure-based therapies have emerged as the most well-established treatment approaches for addressing anxiety disorders among children and adolescents. Pharmacologically, selective serotonin reuptake inhibitors (SSRIs) have been established to be safe and efficacious for the treatment of pediatric anxiety and are considered the medications of choice for this population. Research indicates that CBT plus SSRI medication is the most effective treatment of anxiety for youths ages seven to 17, compared with either CBT or medication alone. Medication monotherapy and CBT monotherapy have also been demonstrated to be effective treatments.

Prediction equations for resting energy expenditure in overweight and normal-weight black and white children.

BACKGROUND: Accurate estimation of children's resting energy expenditure (REE) is important for planning dietary therapy. OBJECTIVE: Our objective was to compare the utility of 5 REE prediction equations in a diverse sample of young children. DESIGN: REE was obtained in 502 black and white girls and boys aged 6-11 y by using indirect calorimetry at 4 US sites. Measured REE and REE predicted from the equations were compared. RESULTS: None of the equations provided both accurate and unbiased estimates of REE. Two new sets of sex-specific equations including race as a factor were generated and evaluated. One set used easily measured variables-females: REE = 0.046 x weight - 4.492 x 1/height(2) - 0.151 x race + 5.841; males: REE = 0.037 x weight - 4.67 x 1/height(2) - 0.159 x race + 6.792-and accounted for 72% and 69%, respectively, of REE variance. The other set used body-composition variables-females: REE = 0.101 x fat-free mass + 0.025 x fat mass + 0.293 x height(3) - 0.185 x race + 1.643; males: REE = 0.078 x fat-free mass + 0.026 x fat mass - 2.646 x 1/height(2) - 0.244 x race + 4.8-and accounted for 75% and 71%, respectively, of REE variance. When split by race and adiposity, the small bias generated could be corrected to within 0.25 MJ (60 kcal) of the mean measured value. CONCLUSION: Sex-specific equations must take race into account to predict REE adequately in children.

Which metric of relative weight best captures body fatness in children?

OBJECTIVE: To evaluate the relative merits of BMI (kilograms per meter squared) and age- and gender-adjusted BMI, age- and gender-specific z score of BMI, and age- and gender-specific percentiles of BMI as surrogate measures of body fatness among a sample of youth. RESEARCH METHODS AND PROCEDURES: The sample comprised 596 children and adolescents 5 to 18.7 years old and was 40% male and 55% white. Height and weight were measured by trained research staff. DXA was used to determine body fat mass. BMI, age- and gender-specific percentile of BMI, and age- and gender-specific z scores of BMI were computed, and these metrics were compared with measured body fatness. RESULTS: The BMI values in the sample ranged from 12.9 to 55.0 kg/m(2), with a mean of 24.9 kg/m(2). The Spearman correlations with percentage body fat were similar for all of the BMI metrics (r = 0.82 to 0.88). Linear regression models with age- and gender-specific percentiles of BMI explained significantly less of the variance (65%) than models with log-transformed BMI (81%) or age- and gender-specific z scores of BMI (75% to 79%). z scores were the most accurate at classifying children who were overfat (sensitivity = 0.84, specificity = 0.96 for z score > or = 1). However, using a BMI > or = 85th percentile or a BMI > or = 20 kg/m(2) was also accurate at classifying youth. DISCUSSION: The BMI metrics had similar correlations with body fatness, but age- and gender-specific percentiles of BMI were the least accurate proxy measure of body fatness. However, a BMI z score > or = 1, BMI percentile > or = 85, and BMI> or = 20 kg/m(2) are all useful for identifying children who may be overfat.

Comparison of the child and parent forms of the Questionnaire on Eating and Weight Patterns in the assessment of children's eating-disordered behaviors.

OBJECTIVE: The assessment of eating-disordered behaviors in middle childhood is challenging. Frequently, both child and parents are queried about the child's eating behavior. However, no direct comparisons between parent and child reports of child eating disturbance have been published. We compared results from the adolescent and parent versions of the Questionnaire on Eating and Weight Patterns (QEWP-A and QEWP-P, respectively) in a nontreatment sample of overweight and normal weight children. METHOD: The QEWP-A and QEWP-P were administered to 142 overweight (body mass index [BMI] > or = 85th percentile) and 121 normal weight (BMI 15th-84th percentile) children, age 9.7 +/- 1.9 years, recruited from the community. RESULTS: The QEWP-A and QEWP-P showed good agreement for the absence of eating-disordered behavior but were not concordant in terms of the number or type of binge eating, overeating episodes, or compensatory weight control behaviors in the past 6 months. Children categorized by their own reports (QEWP-A) as engaging in no overeating, simple overeating, or binge eating behaviors did not differ significantly in body composition or in eating and general psychopathology. Children categorized according to their parents' reports (QEWP-P) as engaging in binge eating had significantly greater body adiposity, eating-disordered cognitions, body dissatisfaction, and parent-reported problems (all ps <.001) than children engaging in no overeating or simple overeating according to the QEWP-P. DISCUSSION: Child and parent reports of eating behaviors are not concordant regarding the presence of binge eating or compensatory behaviors. Further investigation of the utility of these questionnaires is needed before either can serve as a surrogate for a clinical interview.
