Acute Myocardial Infarction and Stress Cardiomyopathy following the Christchurch Earthquakes

Background

Christchurch, New Zealand, was struck by 2 major earthquakes at 4:36am on 4 September 2010, magnitude 7.1 and at 12:51pm on 22 February 2011, magnitude 6.3. Both events caused widespread destruction. Christchurch Hospital was the region''s only acute care hospital. It remained functional following both earthquakes. We were able to examine the effects of the 2 earthquakes on acute cardiac presentations.

Methods

Patients admitted under Cardiology in Christchurch Hospital 3 week prior to and 5 weeks following both earthquakes were analysed, with corresponding control periods in September 2009 and February 2010. Patients were categorised based on diagnosis: ST elevation myocardial infarction, Non ST elevation myocardial infarction, stress cardiomyopathy, unstable angina, stable angina, non cardiac chest pain, arrhythmia and others.

Results

There was a significant increase in overall admissions (p<0.003), ST elevation myocardial infarction (p<0.016), and non cardiac chest pain (p<0.022) in the first 2 weeks following the early morning September earthquake. This pattern was not seen after the early afternoon February earthquake. Instead, there was a very large number of stress cardiomyopathy admissions with 21 cases (95% CI 2.6–6.4) in 4 days. There had been 6 stress cardiomyopathy cases after the first earthquake (95% CI 0.44–2.62). Statistical analysis showed this to be a significant difference between the earthquakes (p<0.05).

Conclusion

The early morning September earthquake triggered a large increase in ST elevation myocardial infarction and a few stress cardiomyopathy cases. The early afternoon February earthquake caused significantly more stress cardiomyopathy. Two major earthquakes occurring at different times of day differed in their effect on acute cardiac events.     

Fat in android, trunk, and peripheral regions varies by ethnicity and race in college aged women

The aim of this study was to determine whether quantity of fat is different across the central (i.e., android, trunk) and peripheral (i.e., arm, leg, and gynoid) regions among young African-American (AA), Asian (AS), Hispanic (HI), and non-Hispanic white (NHW) women. A cohort of 1,161 women (18-30 years) from university physical activity classes were assessed for body composition via dual-emission X-ray absorptiometry (DXA). The mean total body fat percent (TBF%, x = 31.0 ± 7.36%, range = 11.4-54.4%) indicates sufficient variability for the aims. A linear mixed model (LMM) revealed an ethnicity by region fat% interaction (P < 0.0001). Differences existed between ethnicities for each region fat% (all P's < 0.0001) except between HI and AA for the arm region (P = 0.0086) and between AS and NHW for all peripheral regions (P > 0.05). AAs had the highest fat% and HI had the second highest fat% for each region. AS had the third highest fat% for the trunk and android regions. For each ethnicity, the gynoid region had the greatest fat%, followed by the android region, whereas the arm region had the lowest fat%. Future research needs to determine if ethnic differences in central body fat in young women are associated with health outcomes such as cardiovascular disease and insulin resistance.     

Characteristics of chronic nightmares in a trauma-exposed treatment-seeking sample.

Chronic nightmares pose a significant problem for many individuals affected by trauma. The present study attempts to extend current knowledge on the nature, characteristics, and associated sequelae of chronic nightmares. Data were collected from 94 trauma-exposed, treatment-seeking participants (74 women and 20 men). These data suggest that most participants reported their nightmares to be similar or dissimilar to their traumatic experience rather than exact replications (replicative). Not surprisingly, though, nightmare-related distress was positively related to the degree of similarity between their nightmare and their trauma, with replicative nightmares eliciting the greatest distress. Persons with a current diagnosis of posttraumatic stress disorder (PTSD) were more likely to report problems related to nightmares and sleep disturbance than persons without current PTSD. Nonetheless, even after controlling for PTSD-related symptomatology, frequency and severity of nightmares significantly predicted some distress outcomes (e.g., poor sleep quality), suggesting that nightmares contribute to psychological distress above and beyond PTSD symptoms. Implications for future research, and for the treatment of nightmares and PTSD, are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Central nervous system involvement in the autonomic responses to psychological distress

Psychological distress can trigger acute coronary syndromes and sudden cardiac death in vulnerable patients. The primary pathophysiological mechanism that plays a role in stress-induced cardiac events involves the autonomic nervous system, particularly disproportional sympathetic activation and parasympathetic withdrawal. This article describes the relation between psychological distress and autonomic nervous system function, with a focus on subsequent adverse cardiovascular outcomes. The role of the central nervous system in these associations is addressed, and a systematic review is presented of studies examining the association between stress-induced central nervous system responses measured by neuroimaging techniques and autonomic nervous system activation. Results of the systematic review indicate that the primary brain areas involved in the autonomic component of the brain-heart association are the insula, medial prefrontal cortex, and cerebellum (based on 121 participants across three studies that fitted the inclusion criteria). Other areas involved in stress-induced autonomic modulation are the (anterior) cingulate cortex, parietal cortex, somatomotor cortex/precentral gyrus, and temporal cortex. The interaction between central and autonomic nervous system responses may have implications for further investigations of the brain-heart associations and mechanisms by which acute and chronic psychological distress increase the risk of myocardial infarction, cardiac arrhythmias, and sudden cardiac death.     

Faith after an Earthquake: A Longitudinal Study of Religion and Perceived Health before and after the 2011 Christchurch New Zealand Earthquake

On 22 February 2011, Christchurch New Zealand (population 367,700) experienced a devastating earthquake, causing extensive damage and killing one hundred and eighty-five people. The earthquake and aftershocks occurred between the 2009 and 2011 waves of a longitudinal probability sample conducted in New Zealand, enabling us to examine how a natural disaster of this magnitude affected deeply held commitments and global ratings of personal health, depending on earthquake exposure. We first investigated whether the earthquake-affected were more likely to believe in God. Consistent with the Religious Comfort Hypothesis, religious faith increased among the earthquake-affected, despite an overall decline in religious faith elsewhere. This result offers the first population-level demonstration that secular people turn to religion at times of natural crisis. We then examined whether religious affiliation was associated with differences in subjective ratings of personal health. We found no evidence for superior buffering from having religious faith. Among those affected by the earthquake, however, a loss of faith was associated with significant subjective health declines. Those who lost faith elsewhere in the country did not experience similar health declines. Our findings suggest that religious conversion after a natural disaster is unlikely to improve subjective well-being, yet upholding faith might be an important step on the road to recovery.     

Preempting Performance Challenges: The Effects of Inoculation Messaging on Attacks to Task Self-Efficacy

Although inoculation messages have been shown to be effective for inducing resistance to counter-attitudinal attacks, researchers have devoted relatively little attention toward studying the way in which inoculation theory principles might support challenges to psychological phenomena other than attitudes (e.g., self-efficacy). Prior to completing a physical (i.e., balance) task, undergraduates (N = 127, M_age = 19.20, SD = 2.16) were randomly assigned to receive either a control or inoculation message, and reported their confidence in their ability regarding the upcoming task. During the task, a confederate provided standardized negative feedback to all participants regarding their performance, and following the completion of the task, participants again reported their self-efficacy along with measures assessing in-task processes. Findings supported the viability of efficacy inoculation; controlling for pre-task self-efficacy, task performance, and relevant psycho-social variables (e.g., resilience, self-confidence robustness), participants in the inoculation condition reported greater confidence in their ability (i.e., task self-efficacy) than those in the control condition at post-task. Relative to those in the inoculation condition, participants in the control condition also experienced greater concentration disruption and self-presentation concerns during the task.     

Timing of Expression of r and Its Encoding mRNAs in the Developing Cerebral Neocortex and Cerebellum of the Mouse

The expression of tau mRNA and of the corresponding encoded protein variants was studied during postnatal development in two brain regions differing in their timing of differentiation: the cerebral neocortex and the cerebellum. (a) The expression of tau mRNA was different in the two regions. Maximal contents were found at early stages in the cerebral neocortex, with a 10-fold decrease at later stages. In the cerebellum, two peaks of tau mRNA were observed soon after birth and in adulthood, with minimal values at postnatal day 6. (b) The expression of total tau proteins was similar to that of their encoding mRNAs in the cerebral neocortex, i.e., high concentrations after birth and low contents at later stages. In contrast, two peaks of tau proteins were observed in the cerebellum: the first perinatally and the second with a maximum at postnatal day 15. (c) Both in the cerebral neocortex and especially in the cerebellum, increasing concentrations of mature tau variants were expressed at late developmental stages, i.e., when total tau protein contents were decreased. In conclusion, the fluctuations in expression of tau and of its encoding mRNA seen in the cerebellum seem to reflect differences in the timing of differentiation of the various cell types, i.e., the macroneurons and the interneurons, present in this brain region. The adult tau variants appear in both the neocortex and the cerebellum only at late developmental stages, i.e., when most of the circuitry has been established, although these two regions markedly differ in their timing of differentiation.     

Evolution of the terminal regions of the Streptomyces linear chromosome

Comparative analysis of the Streptomyces chromosome sequences, between Streptomyces coelicolor, Streptomyces avermitilis, and Streptomyces ambofaciens ATCC23877 (whose partial sequence is released in this study), revealed a highly compartmentalized genetic organization of their genome. Indeed, despite the presence of specific genomic islands, the central part of the chromosome appears highly syntenic. In contrast, the chromosome of each species exhibits large species-specific terminal regions (from 753 to 1,393 kb), even when considering closely related species (S. ambofaciens and S. coelicolor). Interestingly, the size of the central conserved region between species decreases as the phylogenetic distance between them increases, whereas the specific terminal fraction reciprocally increases in size. Between highly syntenic central regions and species-specific chromosomal parts, there is a notable degeneration of synteny due to frequent insertions/deletions. This reveals a massive and constant genomic flux (from lateral gene transfer and DNA rearrangements) affecting the terminal contingency regions. We speculate that a gradient of recombination rate (i.e., insertion/deletion events) toward the extremities is the force driving the exclusion of essential genes from the terminal regions (i.e., chromosome compartmentalization) and generating a fast gene turnover for strong adaptation capabilities.     

Effectiveness of Group Problem Management Plus,a brief psychological intervention for adults affected by humanitarian disasters in Nepal: A cluster randomized controlled trial

BackgroundGlobally, 235 million people are impacted by humanitarian emergencies worldwide, presenting increased risk of experiencing a mental disorder. Our objective was to test the effectiveness of a brief group psychological treatment delivered by trained facilitators without prior professional mental health training in a disaster-prone setting.Methods and findingsWe conducted a cluster randomized controlled trial (cRCT) from November 25, 2018 through September 30, 2019. Participants in both arms were assessed at baseline, midline (7 weeks post-baseline, which was approximately 1 week after treatment in the experimental arm), and endline (20 weeks post-baseline, which was approximately 3 months posttreatment). The intervention was Group Problem Management Plus (PM+), a psychological treatment of 5 weekly sessions, which was compared with enhanced usual care (EUC) consisting of a family psychoeducation meeting with a referral option to primary care providers trained in mental healthcare. The setting was 72 wards (geographic unit of clustering) in eastern Nepal, with 1 PM+ group per ward in the treatment arm. Wards were eligible if they were in disaster-prone regions and residents spoke Nepali. Wards were assigned to study arms based on covariate constrained randomization. Eligible participants were adult women and men 18 years of age and older who met screening criteria for psychological distress and functional impairment. Outcomes were measured at the participant level, with assessors blinded to group assignment. The primary outcome was psychological distress assessed with the General Health Questionnaire (GHQ-12). Secondary outcomes included depression symptoms, posttraumatic stress disorder (PTSD) symptoms, “heart–mind” problems, social support, somatic symptoms, and functional impairment. The hypothesized mediator was skill use aligned with the treatment’s mechanisms of action. A total of 324 participants were enrolled in the control arm (36 wards) and 319 in the Group PM+ arm (36 wards). The overall sample (N = 611) had a median age of 45 years (range 18–91 years), 82% of participants were female, 50% had recently experienced a natural disaster, and 31% had a chronic physical illness. Endline assessments were completed by 302 participants in the control arm (36 wards) and 303 participants in the Group PM+ arm (36 wards). At the midline assessment (immediately after Group PM+ in the experimental arm), mean GHQ-12 total score was 2.7 units lower in Group PM+ compared to control (95% CI: 1.7, 3.7, p < 0.001), with standardized mean difference (SMD) of −0.4 (95% CI: −0.5, −0.2). At 3 months posttreatment (primary endpoint), mean GHQ-12 total score was 1.4 units lower in Group PM+ compared to control (95% CI: 0.3, 2.5, p = 0.014), with SMD of −0.2 (95% CI: −0.4, 0.0). Among the secondary outcomes, Group PM+ was associated with endline with a larger proportion attaining more than 50% reduction in depression symptoms (29.9% of Group PM+ arm versus 17.3% of control arm, risk ratio = 1.7, 95% CI: 1.2, 2.4, p = 0.002). Fewer participants in the Group PM+ arm continued to have “heart–mind” problems at endline (58.8%) compared to the control arm (69.4%), risk ratio = 0.8 (95% CI, 0.7, 1.0, p = 0.042). Group PM+ was not associated with lower PTSD symptoms or functional impairment. Use of psychosocial skills at midline was estimated to explain 31% of the PM+ effect on endline GHQ-12 scores. Adverse events in the control arm included 1 suicide death and 1 reportable incidence of domestic violence; in the Group PM+ arm, there was 1 death due to physical illness. Study limitations include lack of power to evaluate gender-specific effects, lack of long-term outcomes (e.g., 12 months posttreatment), and lack of cost-effectiveness information.ConclusionsIn this study, we found that a 5-session group psychological treatment delivered by nonspecialists modestly reduced psychological distress and depression symptoms in a setting prone to humanitarian emergencies. Benefits were partly explained by the degree of psychosocial skill use in daily life. To improve the treatment benefit, future implementation should focus on approaches to enhance skill use by PM+ participants.Trial registrationClinicalTrials.gov {"type":"clinical-trial","attrs":{"text":"NCT03747055","term_id":"NCT03747055"}}NCT03747055.

Sex Workers Perspectives on Strategies to Reduce Sexual Exploitation and HIV Risk: A Qualitative Study in Tijuana,Mexico

Globally, female sex workers are a population at greatly elevated risk of HIV infection, and the reasons for and context of sex industry involvement have key implications for HIV risk and prevention. Evidence suggests that experiences of sexual exploitation (i.e., forced/coerced sex exchange) contribute to health-related harms. However, public health interventions that address HIV vulnerability and sexual exploitation are lacking. Therefore, the objective of this study was to elicit recommendations for interventions to prevent sexual exploitation and reduce HIV risk from current female sex workers with a history of sexual exploitation or youth sex work. From 2010–2011, we conducted in-depth interviews with sex workers (n = 31) in Tijuana, Mexico who reported having previously experienced sexual exploitation or youth sex work. Participants recommended that interventions aim to (1) reduce susceptibility to sexual exploitation by providing social support and peer-based education; (2) mitigate harms by improving access to HIV prevention resources and psychological support, and reducing gender-based violence; and (3) provide opportunities to exit the sex industry via vocational supports and improved access to effective drug treatment. Structural interventions incorporating these strategies are recommended to reduce susceptibility to sexual exploitation and enhance capacities to prevent HIV infection among marginalized women and girls in Mexico and across international settings.     

Seed Reduction in Prairie Cordgrass, Spartina pectinata Link., by the Floret-Feeding Caterpillar Aethes spartinana (Barnes and McDunnough)

Insect damage to prairie cordgrass, Spartina pectinata Link., is conspicuously high in Illinois, where attempts to collect native seed show the majority of spikelets damaged with small holes. Dissection of spikes during summer reveals minute caterpillars boring though glumes and feeding on florets inside. In 2009?C2010, panicles of prairie cordgrass from across its native range were used to estimate the percentage of insect-related damage and losses to seed production. Collections of caterpillars from panicles and stems were used to identify one floret-feeding species, estimate its distribution in the central USA, and assess its feeding patterns within spikes. Insect feeding damaged 38% of spikelets across eight states, though injury differed significantly between states. Regression of developed prairie cordgrass seeds onto insect damage suggests a 1:1 loss ratio (i.e., 50% damaged spikelets reduces seed production by 50%). Collections of caterpillars from six midwestern states suggest that larvae of a tortricid moth, Aethes spartinana (Barnes and McDunnough), are responsible for most insect damage to cordgrass spikelets. Larvae of A. spartinana generally feed on a series of consecutive spikelets, with high infestations (>50% insect damage) showing damage concentrated in the middle of spikes. Because larvae are concealed by moving into adjacent spikelets and later tunneling into cordgrass stems, they may be difficult to control using insecticides. While direct effects of the caterpillar on biomass yields for prairie cordgrass are not known, for states like Illinois (where damage to spikelets often exceeds 70%), breeding and seed production efforts may be severely limited without efforts to manage A. spartinana.     

Can positive income anticipations reverse the mental health impacts of negative income anxieties?

Prospect theory suggests losses are more influential than equivalent sized gains in individual level decision-making. Extending this literature, we use longitudinal National Population Health Survey data (2000–01 to 2010–11) to investigate whether experienced psychological distress impacts of greater economic insecurity for working age Canadians can be fully reversed by equal sized increases in security. Economic insecurity (security) is defined as the probability of an annual income decrease (increase) of 25 percent or more. Our identification strategy employs fixed effects estimation and a set of instruments to control for unobserved heterogeneity and reverse causality. Results suggest that an initial one standard deviation increase in economic insecurity predicts a rise in psychological distress of about 0.57 standard deviations for males and 0.54 standard deviations for females. Good economic news of a similar magnitude has considerably less impact, reducing psychological distress by 0.16 and 0.35 standard deviations for males and females respectively.     

Quantifying spatiotemporal patterns concerning land change in Changsha,China

Changsha has undergone speedy socio-economic development, rapid modification of industrial structure, and acceleration of urbanization, which has influenced land cover change during the most recent three decades. Policies have aimed to conserve total agricultural area, but it is not clear how successful these policies have been. Our purpose is to characterize and interpret spatiotemporal patterns of land change with respect to the policy to maintain agricultural area in Changsha, China. Maps at 1990, 2000, and 2010 show four land categories: Built, Forest, Crop and Other. We compute change components and apply Intensity Analysis to compare the land changes during two time intervals: 1990–2000 and 2000–2010. We also compare the central region to the peripheral region during 1990–2010. The maps show that Changsha’s land change accelerated from 1990–2000 to 2000–2010. Change was more intensive in the central region than in the peripheral region. Crop and Forest experienced net decreases while Built experienced net increase during both time intervals and in both regions. Built’s gain targeted Crop and avoided Forest during both time intervals and in both regions. The central region’s largest change component is quantity change, due to Built’s net gain. The peripheral region’s largest change component is exchange, due to simultaneous transitions from Forest to Crop and from Crop to Forest. According to these data, policies have not maintained the quantity of Crop, as the peripheral region has not gained Crop sufficiently to compensate for Crop’s loss from the central region.     

<Emphasis Type="Italic">Susto</Emphasis> and<Emphasis Type="Italic"> Nervios</Emphasis>: Expressions for Stress and Depression

Folk illnesses that are cultural constructions of psychological distress offer a vehicle for the cross-cultural study of stress and stress-related morbidity. This study explores the relationship between the Latin American folk illnesses susto and nervios and mental health. We hypothesize that these folk illnesses are distinct and that there is a stronger association between current levels of stress and depressive symptoms with past experience of nervios than with susto, because the cultural constructions of these folk illnesses reflect chronic and acute concepts of distress, respectively. Interviews were conducted in Guadalajara, Mexico, where participants responded to questions about their socio-demographic characteristics, stress, depressive symptoms, and whether they had experienced susto or nervios. Susto and nervios are very prevalent and occur across sociodemographic subgroups, with the exception that nervios occurred more often in women (p < 0.05). Susto was significantly associated with stress and depressive symptoms (p < 0.05), but nervios had a much stronger association (p < 0.0001), even after controlling for gender. Susto and nervios were expressions of psychological distress; most of those with depression reported susto and/or nervios. This study validates the link between these folk illnesses and stress and depression and may, ultimately, facilitate cross-cultural research on stress.

World Health Organization's low-intensity psychosocial interventions: a systematic review and meta-analysis of the effects of Problem Management Plus and Step-by-Step

Many societies have been recently exposed to humanitarian and health emergencies, which have resulted in a large number of people experiencing significant distress and being at risk to develop mental disorders such as depression, anxiety and post-traumatic stress disorder. The World Health Organization has released a series of scalable psychosocial interventions for people impaired by distress in communities exposed to adversities. Prominent among these is a low-intensity transdiagnostic psychosocial intervention, Problem Management Plus (PM+), and its digital adaptation Step-by-Step (SbS). This systematic review is the first to summarize the available evidence on the effects of PM+ and SbS. Up to March 8, 2023, five databases were searched for randomized controlled trials examining the effects of PM+ or SbS on distress indicators (i.e., general distress; anxiety, depressive or post-traumatic stress disorder symptoms; functional impairment, self-identified problems) and positive mental health outcomes (i.e., well-being, quality of life, social support/relationships). We performed random-effects multilevel meta-analyses on standardized mean differences (SMDs) at post-intervention and short-term follow-up assessments. Our search yielded 23 eligible studies, including 5,298 participants. We found a small to medium favorable effect on distress indicators (SMD=–0.45, 95% CI: –0.56 to –0.34) and a small beneficial effect on positive mental health outcomes (SMD=0.31, 95% CI: 0.14-0.47), which both remained significant at follow-up assessment and were robust in sensitivity analyses. However, our analyses pointed to substantial between-study heterogeneity, which was only partially explained by moderators, and the certainty of evidence was very low across all outcomes. These results provide evidence for the effectiveness of PM+ and SbS in reducing distress indicators and promoting positive mental health in populations exposed to adversities, but a larger high-quality evidence base is needed, as well as research on participant-level moderators of the effects of these interventions, their suitability for stepped-care programs, and their cost-effectiveness.

为揭示农业用地减少热点的驱动因子时空变异特征,本文以无锡市为研究对象,在多时相LandsatTM遥感影像的支持下,应用邻域分析法和Logistic回归模型对1995—2010年农业用地动态变化及驱动机制进行了研究。结果表明:研究区农业用地面积不断减小,减少热点主要分布于主要城市及乡镇周围,其空间格局经历了较分散、相对集中、更加分散3个阶段;可达性因子对农业用地的影响在不同时期基本一致,农业用地减少的相对速度随可达性的上升而增加;经济因子和社会人口因子对农业用地减少影响强烈,但具有较强的阶段性和区位差异性;地形要素等自然环境因子对农业用地减少的作用强度相对较小,但在不同时期各区位表现出较显著的影响。总体上,对农业用地减少影响最大的景观因子逐渐由交通可达性、地形等自然地理要素演变为工业生产总值及人均收入等经济、社会要素;经济、社会要素对农业用地变化的影响随景观发育而逐渐增强。     

Mapping Architectural, Phenological, and Fruit Quality QTLs in Apricot

The F1 population “Harostar”?×?“Rouge de Mauves” was used to perform a quantitative trait loci (QTL) mapping for tree architecture traits (i.e., tree diameter, total branch number, tree shape); time to initial reproductive bud break; and fruit quality traits (i.e., ground color, fruit form, soluble solid content) using data collected from 2010 to 2012. For architectural traits, interval mapping detected QTLs only in “Rouge de Mauves” on linkage group 1 for trunk diameter in 2010, on LG6 for total branch number in 2010, and on LG1 and LG5 for tree shape for both years 2010 and 2011 combined. QTLs were detected only in “Harostar” for time to initial reproductive bud break on LG1 and LG4 in 2011. For fruit quality traits, data were collected in 2011 and 2012. QTLs were identified on LG1 in 2011 and on LG4 in 2012 for soluble solid content, on LG3 for ground color in both years, on LG7 only in 2011, and on LG3 for fruit form in both years. The QTLs that we identified were compared to those previously identified in other Prunus spp.     

Psychological Adjustment of Obese Youth Presenting for Weight Management Treatment

Objective: To determine the prevalence of psychological maladjustment in clinic‐based treatment‐seeking obese children and adolescents (BMI ≥ 95th percentile) and the degree to which maternal, demographic, and youth factors correlate to the youths’ psychological adjustment. Research Methods and Procedures: Anthropometrics, demographics (race, sex, insurance status), measures of youth psychological adjustment (self‐ and mother‐report; Behavior Assessment System for Children), and maternal self‐report of psychological distress (Symptom Checklist 90‐Revised) were collected from 121 obese children and adolescents (55% white, 45% black) and their mothers. Results: Approximately one‐third of youths self‐reported some psychological maladjustment, but two‐thirds of youth were described by their mothers as experiencing some degree of psychological maladjustment. Adjustment difficulties were specific to social functioning, low self‐esteem, and internalizing symptoms. Forty‐one percent of mothers of child participants and 56% of mothers of adolescent participants reported clinically significant psychological distress. Youth self‐report and mother‐report of youths’ psychological difficulties were often most strongly associated with mothers’ level of psychological distress and/or family socioeconomic status rather than to youth characteristics (e.g., percent overweight, race). Discussion: Psychological maladjustment levels among obese youth and their mothers were higher in this clinic‐based sample than in treatment research‐based samples. Present correlate findings extended to obese adolescents and reaffirm a potent association between youth self‐report of their own psychological adjustment and their mother's level of psychological distress. Demographic characteristics and youth weight status were not consistent correlates of youths’ psychological functioning. Findings have implications for the translation of empirically supported pediatric obesity interventions to clinic‐based treatment samples.
