Background. Culturally relevant exercises may help improve health and address disparities faced by older immigrants due to language and cultural barriers. Few studies have focused on such exercise interventions among older Chinese immigrants at US daycare centers. Methods. We conducted a 10-week nonrandomized controlled trial in older Chinese immigrants in Philadelphia, US. The intervention group practiced Chinese Qigong (Baduanjin) 5 days a week guided by trained research assistants and video instructions. The control group maintained their usual daily activities. We collected self-report assessments on overall health, sleep, and fatigue and implemented two computerized cognitive tests measuring psychomotor vigilance task (PVT) and memory twice, preintervention and postintervention. Repeated measures general linear model (GLM) and paired samples t-tests were used for data analyses. Results. Eighty-eight older adults (Qigong, n = 53; control, n = 35) with an average age of 78.13 (SD = 5.05) were included. Groups showed no significant differences at baseline evaluation. After the 10-week exercise, the intervention group showed significant improvements in overall health (), fatigue (), and cognitive functions including memory (), response speed (), and response time () on the PVT, as well as marginally significant benefits in sleep (). Between-group comparisons identified significant group-by-time interactions in health (), sleep (), fatigue (), and memory (). Conclusion. We revealed significant positive effects of Qigong in older Chinese immigrants across multiple health domains. Findings highlight the potential of a …

BackgroundCardiac vagal tone is an indicator of parasympathetic nervous system functioning, and there is increasing interest in its relation to antisocial behavior. It is unclear however whether antisocial individuals are characterized by increased or decreased vagal tone, and whether increased vagal tone is the source of the low heart rate frequently reported in antisocial populations.MethodsParticipants consisted of four groups of community-dwelling adolescent boys aged 15.7 years: (1) controls, (2) childhood-only antisocial, (3) adolescent-only antisocial, and (4) persistently antisocial. Heart rate and vagal tone were assessed in three different conditions: rest, cognitive stressor, and social stressor.ResultsAll three antisocial groups had both lower resting heart rates and increased vagal tone compared to the low antisocial controls across all three conditions. Low heart rate partially mediated the relationship …

Background Schizophrenia is associated with an increased risk of aggressive behaviour, which may partly be explained by illness-related changes in brain structure. However, previous studies have been limited by group-level analyses, small and selective samples of inpatients and long time lags between exposure and outcome. Methods This cross-sectional study pooled data from 20 sites participating in the international ENIGMA-Schizophrenia Working Group. Sites acquired T1-weighted and diffusion-weighted magnetic resonance imaging scans in a total of 2095 patients with schizophrenia and 2861 healthy controls. Measures of grey matter volume and white matter microstructural integrity were extracted from the scans using harmonised protocols. For each measure, normative modelling was used to calculate how much patients deviated (in z-scores) from healthy controls at the individual level. Ordinal regression models were used to estimate the associations of these deviations with concurrent aggressive behaviour (as odds ratios [ORs] with 99% confidence intervals [CIs]). Mediation analyses were performed for positive symptoms (i.e., delusions, hallucinations and disorganised thinking), impulse control and illness insight. Aggression and potential mediators were assessed with the Positive and Negative Syndrome Scale, Scale for the Assessment of Positive Symptoms or Brief Psychiatric Rating Scale. Results Aggressive behaviour was significantly associated with reductions in total cortical volume (OR [99% CI] = 0.88 [0.78, 0.98], p = .003) and global white matter integrity (OR [99% CI] = 0.72 [0.59, 0.88], p = 3.50 x 10-5) and additional …

Monocytes comprise two major subsets, Ly6C hi classical monocytes and Ly6C lo nonclassical monocytes. Notch2 signaling in Ly6C hi monocytes triggers transition to Ly6C lo monocytes, which require Nr4a1, Bcl6, Irf2, and Cebpb. By comparison, less is known...

Biopsychosocial criminological theories suggest that it is important to consider interactions between risk factors from different domains in the prediction of externalizing behavior. Lower resting heart rate is considered the best replicated biological risk factor for externalizing behavior. The psychological construct of empathy has also shown to be predictive of such behavior, but little is known about the potential interaction between these two different risk factors in predicting externalizing behavior. We examined the moderating role of empathy on the association between resting heart rate in childhood and adolescence with externalizing behavior by young adulthood using two subsets of participants from the Longitudinal Risk Factors for Antisocial Behavior project: Subsample 1 (n = 697) at ages 9–10 and 19–20 years and Subsample 2 (n = 394) at ages 14–15 and 19–20 years. Linear and logistic regressions …

Aggression in youth is a transdiagnostic indicator and associated with a variety of serious, maladaptive outcomes. Theoretically, aggression is linked to individual differences in empathy (i.e., the capacity to understand, resonate with, and experience others’ emotions); yet the empirical research is mixed. To clarify this literature, this pre-registered study examined unique associations between subtypes of empathy (cognitive, affective, somatic, positive, and negative) and aggression (reactive, proactive) among a diverse sample of high-risk adolescents (N = 103; Mage=16.1 years, 53% female; 60% racial/ethnic minoritized groups). Empathy was assessed via youth-report at baseline and aggression was assessed at baseline and 9-month follow-up across multiple informants (youth-, parent-, and teacher). Associations were examined simultaneously while controlling for theoretically relevant covariates (age, sex …

Background Lower autonomic arousal is a well-known correlate of criminal offending and other risk-taking behaviors in men, but few studies have investigated this association in women. Aim To test associations between autonomic arousal and criminal offending as well as unintentional injuries among female conscripts. Methods All women born 1958–1994 in Sweden who participated in voluntary military conscription (n = 12,499) were identified by linking Swedish population-based registers. Predictors were resting heart rate (RHR) and systolic blood pressure (SBP). Covariates were height, weight, and physical energy capacity. Main outcomes were criminal convictions (any, violent, and non-violent) from the National Crime Register. Secondary outcome was unintentional injuries requiring medical treatment or causing death. We used survival analyses to test for associations between predictors and outcomes. Results Low RHR, relative to high RHR, was associated with an increased risk of any criminal conviction, non-violent criminal convictions, and unintentional injuries. Low SBP, relative to high SBP, was associated with an increased risk of violent criminal convictions. Conclusions Results support lower autonomic arousal, particularly lower RHR, as a correlate of criminal offending among women that warrants further examination, as the reported findings have potential implications for the prediction of future female crime.

Background and Hypothesis Based on a childhood intervention from ages 3 to 5 years that included additional fish consumption and which resulted in reduced schizotypal personality at age 23, we had previously hypothesized that omega-3 could reduce schizotypy. The current study tests the hypothesis that omega-3 supplementation reduces schizotypy in children. Study Design In this intention-to-treat, randomized, single-blind, stratified, factorial trial, a community sample of 290 children aged 11–12 years were randomized into Omega-3 Only, Cognitive Behavioral Therapy (CBT) Only, Omega-3 + CBT, and Control groups. Schizotypy was assessed using the SPQ-C (Schizotypal Personality Questionnaire for Children) at 0 months (baseline), 3 months (end of treatment), 6 months (3 months post-treatment), and 12 months (9 months post-treatment).
