Background: The purpose of this study was determined whether cognitive impairment is associated with time taken to complete the electronic rapid fitness assessment (eRFA). We hypothesized that taking more time to complete the eRFA will indicate worsened cognitive function. Methods: We retrospectively identified patients who presented to the Memorial Sloan Kettering Cancer Center Geriatrics Service for preoperative evaluation and completed the eRFA as a part of their preoperative assessment from February 2015 to December 2020. Cognitive function was assessed using the Mini‐Cog©, which is a screening test for cognitive function status. Patients in this study underwent elective surgery and had a hospital length of stay ≥1 day. Time to complete the eRFA was automatically recorded by a web‐based tool; assistance with eRFA completion was self‐reported by the patient. In total, 2599 patients were included, of which 2387 had available Mini‐Cog© scores. Results: Overall, 50% of surveys were completed without assistance, 37% were completed with assistance, and 13% were completed by somebody else; Mini‐Cog© scores were lower, corresponding to worsened cognitive function status, in patients requiring assistance (median score respectively, 5 vs. 4 vs. 3; p‐value <0.0001; rates of cognitive impairment 7.5%, 22%, and 38%). Among patients who completed the questionnaire independently, greater cognitive impairment was associated with longer time to complete the eRFA (change in score per 5 min = −0.09; 95% CI −0.14, −0.03; p = 0.002). Conclusions: We found evidence that requirement for assistance in completing web‐based questionnaires, and time taken to complete a questionnaire, predict which patients benefit from more comprehensive cognitive function assessments. Future studies should further validate this finding in a more diverse population and establish optimal clinical pathways. [ABSTRACT FROM AUTHOR]

Background: It has yet to be fully elucidated how differing populations of obstetric patients adapted to the disruptions in perinatal care and postpartum support from the COVID‐19 pandemic. We surveyed an enriched sample of socioeconomically advantaged patients to understand the influence of COVID‐19 on their perinatal care experience, well‐being, and coping. Methods: We surveyed pregnant and postpartum patients (n = 6140) at a large academic medical center in the Midwest of the United States using the Coronavirus and Perinatal Experiences instrument in Spring 2021. Results: The survey was sent to 6141 pregnant and postpartum patients; 1180 (17.8%) respondents completed the survey, including 256 who were pregnant and 834 postpartum. Most pregnant patients experienced no changes in their prenatal care with 16.5% indicating somewhat worsened care. In the postpartum cohort, 37.5% stated their care had somewhat worsened. In describing influences on stress and mental health, 58.1% of postpartum respondents stated it was moderately, and 17.4% significantly, worse. The pandemic had a somewhat or moderately negative influence for 72.7% of respondents, with 11.0% stating these effects were extremely negative. Both cohorts characterized a range of coping strategies, most commonly, talking with friends and family (76.3%). Conclusion(s): Even among this sample of socioeconomically advantaged patients, respondents indicated that the pandemic disrupted many facets of their medical care and daily life, especially social activities and postpartum support. Our findings suggest that counseling on coping and adaptation strategies for stressors and increased health systems support be part of perinatal care during public health emergencies for all demographic groups.

BACKGROUND: Adolescents are in a unique developmental stage, ideal for initiating healthy behaviors and benefiting from health promotion interventions. In this study, we used positive youth development and resilience frameworks, to investigate the role of internal assets as a protective factor for bullying and emotional distress among early adolescents, with attention to whether those associations vary by sex. METHODS: This is a secondary analysis of the 2013 Minnesota Student Survey, a cross‐sectional, population‐based survey of Minnesota youth. Participating eighth grade students (N = 42,841) reported on internal assets, physical, relational and cyberbullying involvement, and emotional distress. RESULTS: Logistic regression analyses, stratified by sex and controlling for sociodemographic characteristics, revealed that students with higher internal assets had lower odds of all forms of bullying victimization and perpetration than those with lower internal assets. Higher levels of internal assets were also associated with lower odds of emotional distress. All associations were significant for boys and girls, but appeared stronger for girls. CONCLUSIONS: Findings indicate that internal assets may buffer young teens from bullying and from the emotional distress that may result from bullying involvement. Approaches bolstering internal assets may be beneficial for combating bullying and emotional distress during early adolescence. [ABSTRACT FROM AUTHOR]

ABSTRACT BACKGROUND Peer harassment can have serious implications for students' success and well-being, and prevention programs need to consider the school context. This study aimed to: (1) identify groups of similar schools based on their risk and protective factors and demographic characteristics and (2) examine associations between school profiles and students' bullying involvement. METHODS Data came from 505 schools and 122,106 students who completed the 2013 Minnesota Student Survey. School-level risk and protective factors and demographic characteristics were included in a latent profile analysis ( LPA) to identify profiles of schools. Multilevel logistic regression was used to assess associations between school profiles and peer harassment. RESULTS Six qualitatively different school profiles were identified. Unadjusted models showed that schools with higher levels of risk had greater odds of peer harassment. However, after controlling for student-level risk and protection, regardless of school-level risk, students in metro-area schools with a more diverse student body reported lower odds of bullying involvement. CONCLUSIONS These findings highlight the importance of the social environment into peer harassment. In addition to addressing student-level risk and protection, larger community factors and norms also need to be taken into account for developing, selecting, and implementing the most effective approaches to bullying prevention.

Background: Studies have demonstrated a robust association between interpersonal callousness (IC) and the development of severe and chronic conduct problems (CP) in youth. Although children exhibiting IC are also believed to be at particularly high risk for developing psychopathic personality features in adulthood, there is little longitudinal evidence supporting this assumption, particularly after controlling for co-occuring CP severity. Methods: This study used data collected on a longitudinal cohort of boys (n = 508), with an oversampling of youth exhibiting elevated conduct problems. Analyses examined the unique and interactive association between latent growth curve trajectories of IC and CP assessed bi-annually from late childhood to early adolescence (~ages 10-13) and features of psychopathy in early adulthood (age ~ 24) assessed using the Psychopathy Checklist - Short Version (PCL:SV; Hart, Cox, & Hare, 1995). Results: Growth curve analysis indicated that initial levels of IC and CP in childhood (~age 10 intercept) both uniquely predicted the development of the interpersonal/affective features of adult psychopathy, and boys with a combination of high initial levels of IC and CP were at particularly high risk for developing the impulsive/antisocial features of the disorder. Boys who exhibited systematic increases in CP from late childhood to early adolescence also demonstrated higher adult psychopathy scores, but changes in IC across this developmental period did not significantly add to the prediction of adult psychopathy. Conclusions: Findings highlight the importance of developing targeted interventions for boys exhibiting severe IC and CP in childhood, as they appear to be at high risk for developing adult psychopathic features.

Background Neurobehavioral consequences of heavy prenatal alcohol exposure are well documented; however, the role of age or sex in these effects has not been studied. The current study examined the effects of prenatal alcohol exposure, sex, and age on neurobehavioral functioning in children. Methods Subjects were 407 youth with prenatal alcohol exposure ( n = 192) and controls ( n = 215). Two age groups (child [5 to 7 years] or adolescent [10 to 16 years]) and both sexes were included. All subjects completed standardized neuropsychological testing, and caregivers completed parent-report measures of psychopathology and adaptive behavior. Neuropsychological functioning, psychopathology, and adaptive behavior were analyzed with separate 2 (exposure history) × 2 (sex) × 2 (age) multivariate analyses of variance (MANOVAs). Significant effects were followed by univariate analyses. Results No 3-way or 2-way interactions were significant. The main effect of group was significant in all 3 MANOVAs, with the control group performing better than the alcohol-exposed group on all measures. The main effect of age was significant for neuropsychological performance and adaptive functioning across exposure groups with younger children performing better than older children on 3 measures (language, communication, socialization). Older children performed better than younger children on a different language measure. The main effect of sex was significant for neuropsychological performance and psychopathology; across exposure groups, males had stronger language and visual spatial scores and fewer somatic complaints than females. Conclusions Prenatal alcohol exposure resulted in impaired neuropsychological and behavioral functioning. Although adolescents with prenatal alcohol exposure may perform more poorly than younger exposed children, the same was true for nonexposed children. Thus, these cross-sectional data indicate that the developmental trajectory for neuropsychological and behavioral performance is not altered by prenatal alcohol exposure, but rather, deficits are consistent across the 2 age groups tested. Similarly, observed sex differences on specific measures were consistent across the groups and do not support sexually dimorphic effects in these domains. [ABSTRACT FROM AUTHOR]

Background Limited research suggests that alcohol consumed with an artificially sweetened mixer (e.g., diet soft drink) results in higher breath alcohol concentrations ( Br ACs) compared with the same amount of alcohol consumed with a similar beverage containing sugar. The purpose of this study was to determine the reliability of this effect in both male and female social drinkers and to determine if there are measureable objective and subjective differences when alcohol is consumed with an artificially sweetened versus sugar-sweetened mixer. Methods Participants ( n = 16) of equal gender attended 3 sessions where they received 1 of 3 doses (1.97 ml/kg vodka mixed with 3.94 ml/kg Squirt, 1.97 ml/kg vodka mixed with 3.94 ml/kg diet Squirt, and a placebo beverage) in random order. Br ACs were recorded, as were self-reported ratings of subjective intoxication, fatigue, impairment, and willingness to drive. Objective performance was assessed using a cued go/no-go reaction time task. Results Br ACs were significantly higher in the alcohol + diet beverage condition compared with the alcohol + regular beverage condition. The mean peak Br AC was 0.091 g/210 l in the alcohol + diet condition compared with 0.077 g/210 l in the alcohol + regular condition. Cued go/no-go task performance indicated the greatest impairment for the alcohol + diet beverage condition. Subjective measures indicated that participants appeared unaware of any differences in the 2 alcohol conditions, given that no significant differences in subjective ratings were observed for the 2 alcohol conditions. No gender differences were observed for Br ACs, and objective and subjective measures. Conclusions Mixing alcohol with a diet soft drink resulted in elevated Br ACs, as compared with the same amount of alcohol mixed with a sugar-sweetened beverage. Individuals were unaware of these differences, a factor that may increase the safety risks associated with drinking alcohol. [ABSTRACT FROM AUTHOR]

Aim To determine the effects of in utero exposure to methadone or buprenorphine on infant neurobehavior. Design Three sites from the Maternal Opioid Treatment: Human Experimental Research ( MOTHER) study, a double-blind, double-dummy, randomized clinical trial participated in this substudy. Setting Medical Centers that provided comprehensive maternal care to opioid-dependent pregnant women in Baltimore, MD, Providence, RI and Vienna, Austria. Participants Thirty-nine full-term infants. Measurements The Neonatal Intensive Care Unit ( NICU) Network Neurobehavioral Scale ( NNNS) was administered to a subgroup of infants on postpartum days 3, 5, 7, 10, 14-15 and 28-30. Findings While neurobehavior improved for both medication conditions over time, infants exposed in utero to buprenorphine exhibited fewer stress-abstinence signs ( P < 0.001), were less excitable ( P < 0.001) and less over-aroused ( P < 0.01), exhibited less hypertonia ( P < 0.007), had better self-regulation ( P < 0.04) and required less handling ( P < 0.001) to maintain a quiet alert state relative to in utero methadone-exposed infants. Infants who were older when they began morphine treatment for withdrawal had higher self-regulation scores ( P < 0.01), and demonstrated the least amount of excitability ( P < 0.02) and hypertonia ( P < 0.02) on average. Quality of movement was correlated negatively with peak NAS score ( P < 0.01), number of days treated with morphine for NAS ( P < 0.01) and total amount of morphine received ( P < 0.03). Excitability scores were related positively to total morphine dose ( P < 0.03). Conclusion While neurobehavior improves during the first month of postnatal life for in utero agonist medication-exposed neonates, buprenorphine exposure results in superior neurobehavioral scores and less severe withdrawal than does methadone exposure.

Aim To determine pre- and post-dosing effects of prenatal methadone compared to buprenorphine on fetal wellbeing. Design A secondary analysis of data derived from the Maternal Opioid Treatment: Human Experimental Research ( MOTHER) study, a double-blind, double-dummy, randomized clinical trial. Setting Six United States sites and one European site that provided comprehensive opioid-dependence treatment to pregnant women. Participants Eighty-one of the 131 opioid-dependent pregnant women completing the MOTHER clinical trial, assessed between 31 and 33 weeks of gestation. Measurements Two fetal assessments were conducted, once before and once after study medication dosing. Measures included mean fetal heart rate ( FHR), number of FHR accelerations, FHR reactivity in the fetal non-stress test ( NST) and biophysical profile ( BPP) score. Findings Significant group differences were found for number of FHR accelerations, non-reactive NST and BPP scores (all Ps < 0.05). There were no significant group differences before time of dosing. Significant decreases (all Ps < 0.05) occurred from pre- to post-dose assessment for mean FHR, FHR accelerations, reactive NST and fetal movement. The decrease in accelerations and reactive NST were significant only for fetuses in the methadone group, and this resulted in a significantly lower likelihood of a reactive NST compared to fetuses in the buprenorphine group. Conclusion Buprenorphine compared with methadone appears to result in less suppression of mean fetal heart rate, fetal heart rate reactivity and the biophysical profile score after medication dosing and these findings provide support for the relative safety of buprenorphine when fetal indices are considered as part of the complete risk-benefit ratio.

Objective To better understand the contribution of age to the development of osteoarthritis (OA). Methods Surgical destabilization of the medial meniscus (DMM) was used to model OA in 12-week-old and 12-month-old male C57BL/6 mice. OA severity was evaluated histologically. RNA used for microarray and real-time polymerase chain reaction analysis was isolated from joint tissue collected from the medial side of the joint, including cartilage, meniscus, subchondral bone, and the joint capsule with synovium. Computational analysis was used to identify patterns of gene expression, and immunohistochemistry was used to evaluate tissue distribution of selected proteins. Results OA was more severe in older mice than in young mice. Only 55 genes showed a similar expression with DMM-induced OA in the 2 age groups, while 493 genes showed differential expression, the majority having increased expression in older mice. Functional categories for similarly expressed genes included extracellular matrix- and cell adhesion-related genes; differentially expressed genes included those related to muscle structure and development and immune response genes. Comparison of expression in sham-operated control joints revealed an age-related decrease in matrix gene expression and an increase in immune and defense response gene expression. Interleukin-33 was present in multiple joint tissue cells, while CCL21 was more localized to chondrocytes and meniscal cells. Periostin was found in the extracellular matrix of cartilage and meniscus. Conclusion Age affects both the basal pattern of gene expression in joint tissues and the response to surgically induced OA. Examining tissue from the joint beyond only cartilage revealed novel genes and proteins that would be important to consider in OA. [ABSTRACT FROM AUTHOR]

Background Consumption of alcohol mixed with energy drinks (Am ED) has been associated with a variety of risks beyond that observed with alcohol alone. Consumers of Am ED beverages are more likely to engage in heavy episodic (binge) drinking. This study was to investigate whether the consumption of high caffeine energy drink mixers with alcohol would increase the desire to drink alcohol compared to the same amount of alcohol alone using a double-blind, within-subjects, placebo-controlled study design. Methods Participants ( n = 26) of equal gender who were social drinkers attended 6 double-blind dose administration sessions that involved consumption of alcohol and energy drinks, alone and in combination. On each test day, participants received 1 of 6 possible doses: (i) 1.21 ml/kg vodka + 3.63 ml/kg decaffeinated soft drink, (ii) 1.21 ml/kg vodka + 3.63 ml/kg energy drink, (iii) 1.21 ml/kg vodka + 6.05 ml/kg energy drink, (iv) 3.63 ml/kg decaffeinated soft drink, (v) 3.63 ml/kg energy drink, and (vi) 6.05 ml/kg energy drink. Following dose administration, participants repeatedly completed self-reported ratings on the Desire-for-Drug questionnaire and provided breath alcohol readings. Results Alcohol alone increased the subjective ratings of 'desire for more alcohol' compared to placebo doses. Energy drink mixers with the alcohol increased desire for more alcohol ratings beyond that observed with alcohol alone. Conclusions This study provides laboratory evidence that Am ED beverages lead to greater desire to drink alcohol versus the same amount of alcohol consumed alone. The findings are consistent with results from animal studies indicating that caffeine increases the rewarding and reinforcing properties of alcohol. [ABSTRACT FROM AUTHOR]

Background There has been a dramatic rise in the consumption of alcohol mixed with energy drinks ( Am EDs) in social drinkers. It has been suggested that Am ED beverages might lead individuals to drink greater quantities of alcohol. This experiment was designed to investigate whether the consumption of Am EDs would alter alcohol priming (i.e., increasing ratings of wanting another drink) compared with alcohol alone. Methods Participants ( n = 80) of equal gender attended 1 session where they were randomly assigned to receive 1 of 4 doses (0.91 ml/kg vodka, 1.82 ml/kg energy drink, 0.91 ml/kg vodka mixed with 1.82 ml/kg energy drink [ Am ED], or a placebo beverage). Alcohol-induced priming of the motivation to drink was assessed by self-reported ratings on the Desire for Drug questionnaire. Results The priming dose of alcohol increased the subjective ratings of 'desire' for more alcohol, consistent with previous research that small doses of alcohol can increase the motivation to drink. Furthermore, higher desire ratings over time were observed with Am EDs compared with alcohol alone. Finally, ratings of liking the drink were similar for the alcohol and Am ED conditions. Conclusions An energy drink may elicit increased alcohol priming. This study provides laboratory evidence that Am ED beverages may lead to greater motivation to drink versus the same amount of alcohol consumed alone. [ABSTRACT FROM AUTHOR]

Background: Chronic pelvic pain (CPP) is a common condition which significantly impacts the quality of life and wellbeing of many women. Laparoscopy with histopathology is recommended for investigation of pelvic pain and identification of endometriosis with concurrent removal. Never‐the‐less, the association between endometriosis and pelvic pain is challenging, with endometriosis identified in only 30–50% of women with pain. Aims: To explore the predictors for undergoing surgery, for identifying endometriosis and endometriosis severity in a cohort of women with CPP. Materials and Methods: This study forms part of the Persistent Pelvic Pain project, a prospective observational cohort study (ANZCTR:ACTRN12616000150448). Women referred to a public gynaecology clinic with pain were randomised to one of two gynaecology units for routine care and followed for 36 months with 6‐monthly surveys assessing demographics, medical history, quality of life, and pain symptoms measured on a Likert scale. Operative notes were reviewed and endometriosis staged. Results: Of 471 women recruited, 102 women underwent laparoscopy or laparotomy, of whom 52 had endometriosis (n = 37 stage I–II; n = 15 Stage III–IV). Gynaecology unit, pelvic pain intensity and lower parity were all predictors of surgery (odds ratio (OR) 0.342; 95% CI 0.209–0.561; OR 1.303; 95% CI: 1.079–1.573; OR 0.767; 95% CI: 0.620–0.949, respectively). There were no predictors identified for endometriosis diagnosis and the only predictor of severity was increasing age (OR 1.155; 95% CI: 1.047–1.310). Conclusions: Gynaecology unit and pain intensity were key predictors of undergoing laparoscopy; however, pain severity did not predict endometriosis diagnosis or staging. These findings indicate the need to review current frameworks guiding practice toward surgery for pelvic pain. [ABSTRACT FROM AUTHOR]

Policy Points:The policy context of direct‐to‐consumer personal genomic testing (DTC‐PGT) has been evolving over the last decade, with little empirical data available about consumers’ perspectives.A majority of consumers of DTC‐PGT supported expanded access to services and their integration into the medical context and opposed more governmental regulation.Consumers’ attitudes about access to services and regulation did not vary based on the specific genetic risk information they received from companies, but may vary based on whether consumers perceived their DTC experience negatively. Context: While policymakers have been considering the appropriateness of direct‐to‐consumer personal genomic testing (DTC‐PGT) for more than a decade, there is little empirical data on consumers’ views regarding the regulation of these products. No research has assessed whether consumers’ personal experience with testing is related to their views about access to and regulation of DTC tests. Methods: Data were analyzed from the PGen Study, a longitudinal prospective cohort of DTC‐PGT customers of 23andMe (n = 564) and Pathway Genomics (n = 377; total N = 941). Consumers were sent an electronic survey before receiving genetic test results and again 6 months after receipt of results. Findings: At the 6‐month follow‐up, more than 80% of participants believed that people have a right to access genetic information directly, that parents should be able to get DTC‐PGT testing for their children, and that genetic information should be kept private. Participants supported health insurance coverage of PGT (60%), wider availability of PGT (68%), and inclusion of genetic information in medical records (63%). Participants were less supportive of government regulation (28%) and restricting testing to clinical settings (14%). Conservative political ideology was associated with less support for government regulation (P < 0.001), as was feeling more confident in one's genetic knowledge (P < 0.05). Participants’ level of computed genetic risk for common diseases, as indicated by their actual test results received from companies, showed no relationship with attitudes. However, those who perceived that they had received elevated risk results expressed lower support for expanded availability and incorporation of PGT into health care (P < 0.01). Those who reported being upset by their genetic test results were less likely to endorse access to DTC products without a medical professional (P < 0.01). Conclusions: PGT consumers supported expanded access to these services and opposed additional regulation. Users who had a negative personal experience with PGT testing were less supportive of expanded availability without a medical professional. [ABSTRACT FROM AUTHOR]

Background: Childhood obesity is underdiagnosed in primary care practices. Our study aimed to compare rates of documentation of diagnosis of obesity and counselling for nutrition and physical activity at an academic primary care practice prior to and following implementation of a body mass index (BMI)‐based electronic point of care clinical reminder tool. Methods: We performed a retrospective record review of children aged 2–18 years undergoing well child visits during any of three calendar years (2009, 2011 and 2013). The electronic clinical reminder tool was implemented in September 2010. Records of children with BMI > 95th percentile were electronically searched for terms of documentation of diagnosis of obesity and nutrition and physical activity counselling. Multivariable logistic regression models were used to adjust for potential patient and provider confounders. Results: Among those with BMI ≥ 95th percentile, there was a statistically significant increase in documentation of diagnosis of obesity (45.5% in 2009 vs. 52.4% in 2011; P < 0.001; adjusted odds ratio 1.36; 95% CI 1.13–1.65) and in counselling for physical activity and nutrition (66.8% in 2009 vs. 75.2% in 2011; P < 0.001; adjusted odds ratio 1.33; 95% CI 1.06–1.66) following implementation of the tool. Compared with 2011, there was no statistically significant increase in documentation of obesity (50.4%) or nutrition and physical activity counselling (77.9%) in 2013. Conclusions: The implementation of a point of care clinical reminder tool was associated with improvement in documentation of diagnosis of obesity and counselling for nutrition and physical activity. Further studies are needed to determine the impact of these automated tools on weight outcomes in children. [ABSTRACT FROM AUTHOR]

BACKGROUND: The purpose of this evaluation was to examine the effects of the LiveWell@School Food Initiative (LW@SFI), a Colorado-based childhood obesity prevention program that partners with school districts to enable them to serve more scratch cooked foods through culinary training, action planning, and equipment grants. METHODS: This evaluation used a quasi-experimental design that examined menu cycles prior to entering the LW@SFI and approximately 1 year later. A review of school menus with food service directors from 9 Colorado school districts was conducted. RESULTS: Data show that districts changed an average of 17.4 entr´ees and 19.7 side dishes over the course of the year. Changes to serving scratch cooked foods were highest for sauces (an increase of 40.5%). No districts were cooking beans/legumes from scratch during baseline or at follow-up. Across the 9 districts, 7 observed statistically significant pre-post reductions in sodium, 4 in fat, 5 in saturated fat, and 3 in calories. CONCLUSIONS: Within a year of implementing the LW@SFI, school districts increased the proportion of fresh, scratch cooked foods they offered and this was associated with some decreases in calories, fat, saturated fat, and sodium, contributing to healthier school food environments.

Background: To evaluate associations between attention-deficit/hyperactivity disorder (ADHD) and comorbid psychiatric disorders using research-identified incident cases of ADHD and population-based controls. Methods: Subjects included a birth cohort of all children born 1976-1982 remaining in Rochester, MN after age five ( n = 5,718). Among them we identified 379 ADHD incident cases and 758 age-gender matched non-ADHD controls, passively followed to age 19 years. All psychiatric diagnoses were identified and abstracted, but only those confirmed by qualified medical professionals were included in the analysis. For each psychiatric disorder, cumulative incidence rates for subjects with and without ADHD were estimated using the Kaplan-Meier method. Corresponding hazard ratios (HR) were estimated using Cox models adjusted for gender and mother's age and education at the subject's birth. The association between ADHD and the likelihood of having an internalizing or externalizing disorder was summarized by estimating odds ratios (OR). Results: Attention-deficit/hyperactivity disorder was associated with a significantly increased risk of adjustment disorders (HR = 3.88), conduct/oppositional defiant disorder (HR = 9.54), mood disorders (HR = 3.67), anxiety disorders (HR = 2.94), tic disorders (HR = 6.53), eating disorders (HR = 5.68), personality disorders (HR = 5.80), and substance-related disorders (HR = 4.03). When psychiatric comorbidities were classified on the internalization-externalization dimension, ADHD was strongly associated with coexisting internalizing/externalizing (OR = 10.6), or externalizing-only (OR = 10.0) disorders. Conclusion: This population-based study confirms that children with ADHD are at significantly increased risk for a wide range of psychiatric disorders. Besides treating the ADHD, clinicians should identify and provide appropriate treatment for psychiatric comorbidities. [ABSTRACT FROM AUTHOR]
