OBJECTIVE:To evaluate the association between attention-deficit/hyperactivity disorder (ADHD) and atypical sensory processing patterns. METHOD/METHODS:For this systematic review and meta-analysis, PubMed, Embase, and Web of Science were searched from their inception until June 30, 2024. Studies examining sensory processing patterns using questionnaires in participants with a diagnosis of ADHD compared with healthy controls were included. The study risk of bias was assessed using a modified Newcastle-Ottawa Scale. A random-effects meta-analysis was conducted using R Version 4.3.1 software, considering sensory modulation severity atypicities as the primary outcome. The risk of publication bias was explored, and sensitivity analyses were conducted to test the robustness of findings. RESULTS:= 97%). Heterogeneity was high in all analyses. Only 9 studies were deemed at overall low risk of bias. CONCLUSION/CONCLUSIONS:Even though available ADHD clinical guidelines do not specifically mention the need to assess sensory processing in ADHD, this meta-analysis suggests that this should be systematically explored in the evaluation of children and adults referred for ADHD. PLAIN LANGUAGE SUMMARY/CONCLUSIONS:This systematic review and meta-analysis examined 30 studies including over 5,000 participants to assess the link between attention-deficit/hyperactivity disorder (ADHD) and atypical sensory processing. Findings show that individuals with ADHD experience significantly higher sensory sensitivity, sensory avoidance, sensory seeking, and low sensory registration compared to controls. Given their impact on daily functioning, assessing sensory processing could improve clinical evaluations for both children and adults with ADHD.

The objective of this study was to explore the buffering effect of support on the association between stress and postpartum depression (PPD) among immigrant women. We surveyed 223 Chinese pregnant or postpartum (within one year post-delivery) immigrant women in New York City. Surveys were conducted in English, Simplified Chinese or Mandarin, March-June 2021. PPD was measured with the Edinburgh PPD scale (EPDS); scores of 13 or higher indicate probable depression. Perceived stress was measured with one question, "How often did you feel stressed in the past week?"; responses were collapsed into a binary measure: Never/Rarely and Sometimes/Often/Always. Support was assessed with a general question about perception of receiving needed support and the Patient-Reported Outcomes Measurement Information System (PROMIS) V2.0 Short Form Informational, Instrumental, and Emotional Support measures. Bivariate and multivariable general linear regression models assessed the relationship among stress, support, and PPD. The EPDS mean score was 11.9 (95%CI:11.1-12.7) and 50% (95%CI: 42-57%) had EPDS scores ≥ 13, indicative of serious symptoms; 56% felt stressed in the past week and 37% reported getting needed support. Among women without perceived needed support, mean EPDS scores were higher among women who were stressed compared with women who were not (adjusted mean difference (aMD) 5.4; 95%CI:3.3-7.5); the association between stress and EPDS score was attenuated among women with needed support (aMD 1.1; 95%CI:-1.0, 3.1). Similar patterns held for emotional and instrumental support. Perceived and social support attenuated the association between perceived stress and depression symptoms among Chinese immigrant women. Enhancing support may be effective in countering the impact of stressors on PPD.

Maternal mental health during the perinatal period has been linked to the development of infant emotion regulation capacity, largely through its impact on caregiver-infant interactions during the first year of life. The majority of studies have focused on the effects of maternal depression, even though maternal anxiety is more prevalent and its effects on infant outcomes are less well understood. The current study aims to 1) explore differences in infant affect and regulatory behaviors across two commonly implemented infant stress-induction paradigms and 2) evaluate the differential effects of depression and anxiety on infant regulatory behaviors. Six-month-old infants and their mothers (N = 126) completed two tasks remotely in the home: the Arm Restraint task and the Still-Face Paradigm. Maternal depression and anxiety symptoms were measured using the Edinburgh Postnatal Depression Scale (EPDS) subscales. Within-person results indicated no significant associations among infant regulatory behaviors nor infant reactivity across the two paradigms. Additionally, no significant associations were found between maternal mental health and infant regulatory behaviors during the Still-Face Paradigm. However, higher EPDS composite scores were associated with fewer infant avoidance behaviors during the Arm Restraint task, and this result was driven by items on the anxiety subscale. These findings suggest that infant regulatory behaviors may differ depending on task used and may also be influenced by subclinical levels of maternal anxiety, but not maternal depression.

OBJECTIVE:This study aimed at identifying moderators of efficacy of stimulants against placebo to inform personalized recommendations for treatment in preschool children (< 6 years) with attention-deficit/hyperactivity disorder (ADHD). METHOD/METHODS:We acquired individual-level participant data from two randomized placebo-controlled trials (RCTs) of preschool ADHD: MAPPA (8-week methylphenidate, 102 participants, Brazil) and SPD489-347 (6-week lisdexamfetamine, 148 participants, US). We evaluated the moderator and predictor effects of baseline demographic (age, sex, race, ethnicity, maternal educational level) and baseline clinical (ADHD symptom severity, intelligence quotient, number of psychiatric comorbidities) characteristics, as available, on endpoint ADHD symptom severity scores. Data from each study were analyzed separately with linear mixed-effects model for repeated measures. For categorical variables, we also computed treatment effects (i.e., stimulants versus placebo) within subgroups and, when possible, pooled them alongside subgroup data from PATS (5-week methylphenidate, 165 participants, US) in random-effects meta-analyses. RESULTS:Stimulants had greater efficacy against placebo in White children compared to Black children considering data from US studies. Older age was not a moderator of greater efficacy of stimulants against placebo, nor was it associated with worse ADHD symptom severity at endpoint. Greater baseline ADHD symptom severity was associated with higher ADHD symptom severity at endpoint independently of the assigned treatment group. CONCLUSION/CONCLUSIONS:Race, but not older age or baseline ADHD symptom severity, may moderate the efficacy of stimulants for preschool ADHD. Given the post hoc nature of subgroup analyses, the findings should be interpreted as exploratory and viewed as hypothesis for confirmation in future studies.

BACKGROUND:Recent epidemiological evidence links early-life obesity and metabolic dysregulation to adult psychosis vulnerability, though a causal relationship remains unclear. Establishing causality in highly heritable psychotic disorders requires 1) demonstrating that early-life metabolic factors mediate between genetic vulnerability and psychosis trajectory, 2) dissecting mechanisms leading to early-life obesity in genetically vulnerable individuals, and 3) clarifying downstream neurodevelopmental pathways linking early-life obesity to psychosis symptoms. METHODS:Here we investigated bidirectional pathways linking behavioral, body mass index (BMI), and neurodevelopmental trajectories in a unique longitudinal cohort of 184 individuals at high genetic risk for psychosis, due to 22q11.2 deletion syndrome (22q11DS), and 182 neurotypical control individuals, followed-up since childhood. We combined repeated BMI measurements with clinical/neurocognitive phenotyping and neuroimaging. We investigated the relationship between BMI trajectories with risk of psychosis and tested whether altered cortical or cerebellar development could underlie this association. RESULTS:Childhood behavioral impulsivity predicted early and progressive deviations in BMI trajectories, mediating the effects of 22q11DS vulnerability to early-life obesity. Chronic BMI increases manifesting during childhood predicted the subsequent emergence of psychosis during late adolescence/early adulthood, mediating the effects of behavioral impulsivity. A dose-effect relationship linked duration of increased BMI status to worsening of motor and cognitive disorganization, a key schizophrenia symptom domain, which was mediated by progressive gray matter volume reductions in posterior-inferior cerebellum. CONCLUSIONS:These findings suggest that metabolic dysregulation associated with obesity may link childhood behavioral impulsivity to psychosis vulnerability in 22q11DS by influencing cerebellar maturation. These findings might support preventive interventions targeting early-life metabolic trajectories in individuals at risk of psychosis.

IMPORTANCE/UNASSIGNED:Studies suggest developmental concerns for infants born during the COVID-19 pandemic, but evidence on its impact on toddler behavioral and emotional well-being remains limited. OBJECTIVE/UNASSIGNED:To assess whether birth timing relative to the COVID-19 pandemic is associated with toddler internalizing and externalizing problems. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This retrospective cohort study utilized Environmental Influences on Child Health Outcomes (ECHO) cohort data collected between September 27, 2009, and July 21, 2023. Children were divided into 3 groups: the prepandemic group, who were born and assessed before March 13, 2020; the pandemic-assessed group, who were born before March 13, 2020, but assessed after that date; and the pandemic-born group, who were born and assessed on or after March 13, 2020. Data were collected from 9 ECHO cohort sites across the United States and Puerto Rico. EXPOSURE/UNASSIGNED:The COVID-19 pandemic, designated as starting on March 13, 2020. MAIN OUTCOME AND MEASURE/UNASSIGNED:Parent-reported internalizing and externalizing symptoms on the Preschool Child Behavior Checklist (CBCL 1½-5) at age 18 to 39 months. RESULTS/UNASSIGNED:The 3438 children (mean [SD] age, 2.33 years [5.38 months]; 1770 [51.5%] male; 537 [16.2%] Black, 1722 [50.1%] Hispanic; and 1538 [44.7%] White) were divided into 3 groups: 1323 in the prepandemic group (mean [SD] age, 2.41 years [5.66 months]); 1690 in the pandemic-assessed group (mean [SD] age, 2.32 years [5.16 months]); and 425 in the pandemic-born group (mean [SD] age, 2.14 years [4.47 months]). Both the pandemic-assessed group (unadjusted β = -1.51; 95% CI, -2.27 to -0.75; adjusted β = -1.73; 95% CI, -2.48 to -0.99) and the pandemic-born group (unadjusted β = -2.03; 95% CI, -3.13 to -0.93; adjusted β = -1.90; 95% CI, -2.99 to -0.80) had lower levels of internalizing problems compared with the prepandemic (ie, historical) group. Similarly, both the pandemic-assessed (unadjusted β = -1.74; 95% CI, -2.46 to -1.02; adjusted β = -1.81; 95% CI, -2.53 to -1.09) and the pandemic-born group (unadjusted β = -3.16; 95% CI, -4.20 to -2.12; adjusted β = -3.17; 95% CI, -4.22 to -2.12) each had lower levels of externalizing problems compared with the prepandemic group. CONCLUSIONS AND RELEVANCE/UNASSIGNED:In this study, toddlers with prenatal and postnatal as well as those with only postnatal COVID-19 pandemic exposure showed fewer internalizing and externalizing problems than those born and assessed prior to the onset of the pandemic. These findings underscore the need for further research to identify protective factors that may buffer the impact of the pandemic on child behavior.

OBJECTIVE:Rates of suicide, anxiety, and depression have soared in US youth, and professional organizations strongly urge earlier identification, particularly in pediatric emergency departments (PEDs). However, there are few commonly used suicide screeners that also identify other mental health (MH) problems. A new, electronically administered instrument, the K-CAT, screens for suicide and multiple MH problems. We hypothesized that the K-CAT would enhance suicide identification compared with routine screening and identify significant anxiety and depression in youth presenting with non-MH chief complaints. METHODS:This observational study was conducted in 2 PEDs. Eligible youth were 7 to 17 accompanied by a caregiver without: severe medical concerns, difficult behaviors, limited verbal language, or only a psychiatric complaint. Of the 341 eligible, 241 (70.7%) were screened, and 228 both presented with a non-MH problem and had complete K-CAT data. A Fisher exact test determined whether suicidal behaviors/ideation rates differed between the K-CAT and retrospective chart review data. RESULTS:Seventy-four or 32.46% of youth scored positive for suicide, anxiety, and/or depression on the K-CAT. Females were more likely to screen positive (P<0.001). Compared with the retrospective data, more youth were identified with suicide risk by the K-CAT (3.95% vs. 0%; P=0.004). Youth identified by the K-CAT were 62.5% female and 33.3% 7 to 11 years. CONCLUSIONS:The K-CAT increases the identification of suicidal ideation and behaviors overall and in younger children. It identifies significant rates of depression and anxiety in youth and could be an important first step in identifying MH problems in youth.

The use of Attention-Deficit/Hyperactivity Disorder (ADHD) medications during pregnancy is increasing, raising concerns about potential long-term effects on offspring. This study investigates in utero exposure to methylphenidate, amphetamines and atomoxetine and risk of offspring neurodevelopmental disorders (NDDs). The population-based cohort study identified from Swedish registers included 861,650 children born by 572,731 mothers from 2008-2017. We categorized exposure based on redeemed medication during pregnancy and compared exposed children to those whose mothers discontinued medication before conception. Main outcomes were any NDD, including ADHD and autism spectrum disorder (ASD). Cox proportional hazards regression estimated hazard ratios (HRs), adjusting for maternal psychiatric and sociodemographic factors. Sensitivity analyses included stratifications by medication type, timing, and duration of exposure, and sibling comparisons. We also performed a meta-analysis combining data from the present study with those from a previous Danish study. Results showed no increased risk for any NDD (HR_adjusted 0.95, 95% CI 0.82-1.11), ADHD (HR_adjusted 0.92, 95% CI 0.78-1.08), or ASD (HR_adjusted 0.86, 95% CI 0.63-1.18). Sensitivity analyses showed consistent patterns of no increased risks across different exposure durations, medication types and between siblings. Meta-analyses further supported the findings (pooled HR for any NDD 1.00, 95% CI 0.83;1.20). Our study provides evidence that in utero exposure to ADHD medications does not increase the risk of long-term NDDs in offspring. This study replicates safety data for methylphenidate and extends it with new safety data on amphetamines and atomoxetine. These findings are crucial for informing clinical guidelines and helping healthcare providers and expectant mothers make informed decisions.

PURPOSE/OBJECTIVE:To estimate the prevalence and geographic variation of serious mental illness (SMI) among young adults enrolled in Medicaid and to identify individual and community-level factors associated with SMI. METHODS:We used New York Medicaid data for over 1.6 million young adults aged 18-34 years with continuous Medicaid enrollment from April 2021 through March 2022. We merged 3 additional county and zip code-level datasets, including the Distressed Communities Index, Area Health Resource File, and New York homelessness data. We used descriptive analyses, data visualization methods, and multivariable logistic regression to estimate the prevalence of SMI and identify individual- (sex, race and ethnicity, age, disability aid, and homelessness) and community-level (geography, community distress, number of hospital beds, and community mental health centers per capita) factors associated with SMI. RESULTS:The 12-month prevalence of SMI was 8.3% in New York State, with wide geographic variation by zip codes, ranging from 0% to 39%. Young adults identifying as Asian, Black, and Latinx (compared to White), and those living in zip codes with the most community distress were associated with lower odds of SMI, odds ratios (OR) ranged from 0.47 (Asian) (95% confidence interval [CI] [0.46-0.49]) to 0.95 (Latinx) (CI [0.93-0.97]). Young adults identifying as female (compared to male), receiving disability, experiencing homelessness, and rural residence were associated with higher odds of SMI, ORs ranged from 1.64 (female) (95% CI [1.62-1.66]) to 5.49 (homelessness) (95% CI [5.33-5.66]). DISCUSSION/CONCLUSIONS:SMI prevalence varies by individual- and community-level factors, including homelessness and rural residence, signaling the need for specific interventions and policies.

Children presenting comorbid attention-deficit/hyperactivity disorder (ADHD) and depression symptoms have higher risks of later suicidal ideation and attempt. However, it is unclear to what extent this risk stems from individual differences in the genetic predisposition for ADHD and/or depression. We investigated the unique and combined contribution of genetic predisposition to ADHD and depression to suicidal ideation and attempt by early adulthood. Data were from two longitudinal population-based birth cohorts, the Quebec Longitudinal Study of Child Development and the Quebec Newborn Twin Study (total N = 1207). Genetic predisposition for ADHD and depression were measured using polygenic scores. Suicidal ideation and attempt by age 20 years were self-reported via questionnaires. Across the two cohorts, suicidal ideation and attempt were reported by 99 (8.2%) and 75 (6.1%) individuals, respectively. A higher polygenic score for depression was associated with significantly higher risk of suicidal ideation and attempt, while no significant associations were found for ADHD polygenic score. However, we found an interaction between polygenic scores for depression and ADHD in the association with suicide attempt (P = 0.012), but not suicidal ideation (P = 0.897). The association between polygenic score for depression and suicide attempt was significantly stronger for individuals with a higher polygenic score for ADHD. Individuals scoring ≥ 1-SD above the mean for both polygenic scores were at increased risk for suicide attempt compared to individuals with lower scores (OR 4.03, CI 1.64-9.90), as well as compared to individuals scoring ≥ 1-SD above the mean in only depression (OR 2.92, CI 1.01-8.50) or only ADHD (OR 4.88, CI 1.56-15.26) polygenic scores. Our findings suggest that genetic predisposition for ADHD and depression contributes to increase the risk of suicide attempt in a multiplicative, rather that additive, way. Our results contribute to our understanding of the etiology of suicide risk and may inform screening and risk stratification.
