Psychosocial stress impairs health behavior in patients with mental disorders

Psychological indicators for healthy aging: validation of the German short version of Ryff's scales of psychological well-being (SPWB)

BACKGROUND

The important roles of well-being as realization of one's true potential for healthy aging have been highlighted by literature of the recent decades. The Scales of Psychological Well-being (SPWB) are an internationally recognized measurement tool for psychological well-being. Yet, sound validation of the German SPWB 18-item version has been lacking to date. Therefore, the present study aims to (1) test the psychometric properties of the German SPWB 18-item version in terms of factorial validity and (2) determine construct validity by investigating its correlations with psychosocial variables, mental and physical health. (3) Sociodemographic characteristics of the SPWB in a middle to old age German population was explored.

METHODOLOGY

Data of N = 3,374 participants 45-85 years old of the 10-year follow-up (2017-2022) of the Gutenberg Health Study (GHS) were analyzed. Descriptive analyses and inference statistical analyses were performed to assess construct validity. In order to determine the psychometric properties, item characteristics and reliability coefficients were analyzed. Confirmatory factor analyses tested the proposed theoretical factorial structure.

RESULTS

Construct validity of the SPWB was established with respect to sociodemographic, psychosocial (social support and resilient coping), and health variables (sleeping problems, depression and anxiety symptoms, stress, loneliness, and somatic diseases). Analysis of the psychometric properties of the German SPWB 18-item version rendered support for the theoretically proposed multidimensional structure of psychological well-being in our sample rather than a one factorial structure. Bi-factor models that take the method effects of positively and negatively formulated items into account are highly recommended.

CONCLUSIONS

The German SPWB 18-item version shows comparable psychometric properties to previous large-scale studies from other countries. The SPWB provides psychological indicators for healthy aging.

Prevalence and Association of Suicidal Ideation and High Risk Drinking in Men and Women: Results from a Representative German Household Survey

BACKGROUND

Alcohol abuse and suicide are significant public health problems. Specifically, more than three million people die each year from alcohol abuse and 700,000 from suicide. Research indicates that alcohol abuse is associated with suicidality, and that there are significant gender differences in both. By means of a large representative population sample, this study quantifies the associations between suicidal ideation and alcohol misuse in the German population.

METHODS

Based on a survey of 2,513 individuals from 2015, prevalence estimates and logistic regression models were used to estimate the association between suicidal ideation (i.e., past-year suicidal ideation according to the Suicidal Behavior Questionnaire Revised [SBQ-R] and alcohol consumption (i.e., past year high-risk drinking according to the Alcohol Use Disorders Identification Test [AUDIT-C]).

RESULTS

High-risk drinking (24.78%) and suicidal ideation (5.09%) were highly prevalent in this representative German population sample. These estimates differed significantly between men and women: Men were more likely to report high-risk drinking (30.14%) compared to women (20.56%), while a greater proportion of women (5.95%) reported suicidal ideation when compared to men (4.00%). Moreover, the association of suicidal ideation and high-risk drinking was weaker in women (OR = 1.64 CI 95% [1.03-2.62]) than in men (OR = 5.62 CI 95% [2.72-11.60]).

CONCLUSION

The high prevalence of suicidal ideation and high-risk drinking in women and underscores the necessity for low-level interventions and public health initiatives aimed at prevention and intervention against the escalation of high-risk drinking and suicidal behavior. Prevention efforts should consider gender-specific patterns of risk.

Psychosocial Stressors and Postpartum Depressive Symptoms Are Linked to Postpartum Contraceptive Use

Background: Postpartum contraception plays a critical role in reducing the occurrence of rapid subsequent pregnancy, offering individuals reproductive choice, and promoting overall reproductive planning and well-being. In this study, we investigated the relationship between psychosocial stress during pregnancy, postpartum depressive symptoms (PDS), and postpartum contraceptive use. Materials and Methods: We analyzed data from the Pregnancy Risk Assessment Monitoring System (2012-2019), which included comprehensive information about maternal experiences, views, and needs before, during, and after pregnancy from four states and a large city, with a total sample size of N = 36,356. We conducted descriptive analyses as well as adjusted multivariable logistic regression models. Main Findings: Our findings demonstrate significant negative associations between partner-related (adjusted odds ratio [aOR] = 0.82, 95% confidence interval [95% CI]: 0.76-0.89, p ≤ 0.001) and trauma-related (aOR = 0.83, 95% CI: 0.75-0.92, p ≤ 0.001) stressors and postpartum contraceptive use. Additionally, we observed a negative association between PDS and postpartum contraceptive use (OR = 0.88, 95% CI: 0.80-0.97, p ≤ 0.01), indicating that individuals experiencing PDS are less likely to utilize contraception after giving birth. Furthermore, our study highlights racial/ethnic, socioeconomic, and parity postpartum contraceptive use disparities. Conclusions: Our findings emphasize the importance of incorporating psychosocial stressors and mental health into the promotion of effective postpartum contraception practices. These results have valuable implications for health care providers, policymakers, and researchers as they can guide the development of targeted interventions and support systems to contribute to improved reproductive health outcomes.

Effects of Ketogenic Diet on Increased Ethanol Consumption Induced by Social Stress in Female Mice

Stress is a critical factor in the development of mental disorders such as addiction, underscoring the importance of stress resilience strategies. While the ketogenic diet (KD) has shown efficacy in reducing alcohol consumption in male mice without cognitive impairment, its impact on the stress response and addiction development, especially in females, remains unclear. This study examined the KD's effect on increasing ethanol intake due to vicarious social defeat (VSD) in female mice. Sixty-four female OF1 mice were divided into two dietary groups: standard diet (n = 32) and KD (n = 32). These were further split based on exposure to four VSD or exploration sessions, creating four groups: EXP-STD (n = 16), VSD-STD (n = 16), EXP-KD (n = 16), and VSD-KD (n = 16). KD-fed mice maintained ketosis from adolescence until the fourth VSD/EXP session, after which they switched to a standard diet. The Social Interaction Test was performed 24 h after the last VSD session. Three weeks post-VSD, the Drinking in the Dark test and Oral Ethanol Self-Administration assessed ethanol consumption. The results showed that the KD blocked the increase in ethanol consumption induced by VSD in females. Moreover, among other changes, the KD increased the expression of the ADORA1 and CNR1 genes, which are associated with mechanisms modulating neurotransmission. Our results point to the KD as a useful tool to increase resilience to social stress in female mice.

Influence of depressive disorders, stress, and personality traits on quality of life after cochlear implantation

PURPOSE

This study aimed to determine whether preoperative depressiveness, stress, and personality influence quality of life (QOL) after cochlear implant (CI) surgery.

METHODS

In this prospective study, 79 patients undergoing CI surgery were evaluated preoperatively and 12 months postoperatively. Disease-specific QOL was assessed with the Nijmegen Cochlear Implant Questionnaire (NCIQ) and general QOL with the WHOQOL-BREF. Depressiveness and stress were assessed with the Patient Health Questionnaire (PHQ-D). The Charlson Comorbidity Index (CCI) was used to classify comorbidities. The Big Five Personality Test (B5T) was used to assess the basic personality dimensions. Speech comprehension was evaluated in quiet with the Freiburg monosyllable test and in noise with the Oldenburg sentence test.

RESULTS

After CI surgery, the total NCIQ score improved significantly (Δ 17.1 ± 14.7, p < 0.001). General QOL (WHOQOL-BREF, Δ 0.4 ± 9.9, p = 0.357), stress (Δ 0.25 ± 3.21, p = 0.486), and depressiveness (Δ 0.52 ± 3.21, p = 0.121) were unaffected by CI surgery. Patients without elevated depressiveness (p < 0.01) or stress (p < 0.001) had significantly better total NCIQ scores. The results of the multiple regression analyses show that, after adjusting for the CCI, personality, age, and mental health stress (ß = - 0.495, p < 0.001) was significantly associated with postoperative NCIQ outcome scores. Depressiveness and neuroticism had the strongest influence on the generic QOL (ß = - 0.286 and ß = - 0.277, p < 0.05).

CONCLUSION

Stress symptoms and personality traits are significant predictive factors for disease-specific QOL, as well as hearing status. This should be considered in the preoperative consultation and in optimizing the rehabilitation process.

Investigating the Role of Race and Stressful Life Events on the Smoking Patterns of Pregnant and Postpartum Women in the United States: A Multistate Pregnancy Risk Assessment Monitoring System Phase 8 (2016-2018) Analysis

OBJECTIVE

To examine the smoking patterns of women who experienced stressful life events and the impact of racial disparities on the relationship between stressful life events, and prenatal/ postpartum smoking.

METHODS

The study analyzed data from the Pregnancy Risk Assessment Monitoring System Phase 8 (2016-2018) survey across five states (CT, LA, MA, MO, WI). Four stressful life event categories were created using thirteen affiliated questions: financial, trauma, partner, and emotional. We assessed: 1) the association between smoking and stressful life events, 2) the impact of race on the relation between smoking and stressful life events, and 3) the long-term effects of smoking on health by assessing the association between smoking and maternal morbidity. Bivariate statistics and multivariate Poisson regression models were conducted.

RESULTS

A total of 24,209 women from five states were included. 8.9% of respondents reported smoking during pregnancy, and 12.7% reported smoking postpartum. There was a significant association between all stressful life events and smoking. Trauma stressful life event had the strongest association with smoking during pregnancy (adjusted PR=2.01; CI: 1.79-2.27) and postpartum (adjusted PR= 1.80; CI: 1.64-1.98). Race and stressful life event interaction effects on smoking had varied significant findings, but at least one racial/ ethnic minority group (Black, Hispanic, Asian) had a higher smoking prevalence than non-Hispanic White per stressful life event category. Lastly, the prevalence of maternal morbidity was higher for smoking during pregnancy (adjusted PR= 1.28; CI: 1.19-1.38) and postpartum (adjusted PR= 1.30; CI: 1.22-1.38) compared to no smoking.

CONCLUSIONS FOR PRACTICE

Culturally congruent, multi-disciplinary care teams are needed to address both clinical and social needs to reduce stressful life events and smoking. Screenings for stress should be standardized with a referral system in place to provide ongoing support.

Influência de Fatores Psicológicos e Sociais nos Comportamentos Preventivos de Saúde dos Homens

Introdução: Homens tendem a retardar a procura por serviços de saúde e têm baixa adesão a tratamentos, causando piores indicadores de saúde. Objetivou-se analisar a influência de fatores psicológicos e sociais nos comportamentos preventivos de saúde adotados por homens. Métodos: Utilizaram-se um questionário sociodemográfico, o Inventário de Conformidade com Normas Masculinas (CMNI), o Self-Reporting Questionnaire (SRQ) e o Questionário de Atitudes e Comportamentos de Saúde (QACS). Participaram da análise 315 homens adultos de todo o Brasil. Resultados: Uma regressão linear revelou que eram preditores de menor prevenção: pontuar alto em traços que indicavam desejo por admiração e respeito e comportamentos sexuais arriscados, bem como a maior probabilidade de presença de transtorno mental, ter cor de pele preta e menor nível educacional. Discussão: Foram mapeados fatores de risco para a menor conduta preventiva em homens. Conclusão: Conclui-se que variáveis psicológicas e sociais exercem forte influência sobre os comportamentos de saúde dos homens, sendo necessárias ações de promoção da saúde masculina para além das políticas públicas existentes, na busca pela elaboração de novas ações focadas neste grupo e temática específicos.

Inanspruchnehmende einer Spielsuchtambulanz mit „Doppeldiagnosen“

Zusammenfassung: Zielsetzung: Internetnutzungsstörungen werden als wichtiges gesundheitsrelevantes Phänomen akzeptiert und sind bekanntermaßen mit hohen Raten an komorbiden psychischen Erkrankungen assoziiert. Jedoch ist das Wissen über das gleichzeitige Auftreten mit einer weiteren Verhaltenssucht begrenzt. Die vorliegende Arbeit bietet eine erste klinische Charakterisierung bei gleichzeitig auftretender Internetnutzungs- und Glücksspielstörung (Doppeldiagnose). Methodik: Die Analyse beruhte auf einer konsekutiven klinischen Stichprobe von Betroffenen ( N=1813), die sich wegen einer Verhaltenssucht ambulant vorstellten. Daten wurden aus der klinischen Exploration sowie psychometrischen Verfahren zur Erfassung von Depressivität, Stress, Angstsymptomen und Funktionsniveau erhoben und mit Betroffenen, die entweder eine Computerspiel- oder Glücksspielstörung aufwiesen, verglichen. Ergebnisse: Bei n=46 Betroffenen wurde eine Doppeldiagnose gestellt. Diese Gruppe wies zudem eine höhere Anzahl weiterer psychischer Störungen auf. Die Auswertung der klinischen Inventare wies auf eine insgesamt hohe Symptombelastung hin, ohne dass sich die Gruppen signifikant voneinander unterschieden. Schlussfolgerungen: Eine kleine Gruppe Inanspruchnehmender erfüllt die Kriterien einer Internetnutzungs- und einer Glücksspielstörung. Es ergeben sich keine auffälligen Unterschiede in der Symptombelastung zu Betroffenen mit singulärer Abhängigkeit, jedoch ist zu vermuten, dass Doppeldiagnosen eine differenzierte therapeutische Herangehensweise erfordern.

Early adverse effects of behavioural preventive strategies during the COVID-19 pandemic in Germany: An online general population survey

Background

Quarantine and physical distancing represent the two most important non-pharmaceutical actions to contain the COVID-19 pandemic. Comparatively little is known about possible adverse consequences of these behavioural measures in Germany. This study aimed at investigating potential early adverse effects associated with quarantine and physical distancing at the beginning of the countrywide lockdown in Germany in March 2020.

Method

Using a cross-sectional online survey (N = 4,268), adverse consequences attributed to physical distancing, symptoms of psychopathology, and sociodemographic variables were explored in the total sample as well as in high-risk groups (i.e., people with a physical or mental condition).

Results

The most frequently reported adverse effects were impairment of spare time activities, job-related impairment, and adverse emotional effects (e.g., worries, sadness). Participants with a mental disorder reported the highest levels of adverse consequences (across all domains) compared to participants with a physical disease or participants without any mental or physical condition. No significant association between the duration of the behavioural protective measures and the severity of adverse mental health effects was observed.

Conclusion

Results showed that non-pharmaceutical actions were associated with adverse effects, particularly in people with mental disorders. The findings are of relevance for tailoring support to special at-risk groups in times of behavioural preventive strategies.

Effect of Sopoongsan on Skin Inflammation and Hyperlocomotion in Socially Isolated Mice with Atopic Dermatitis

Psychological stress is a major exacerbating factor of atopic dermatitis (AD), a chronic inflammatory skin disease. Sopoongsan (SPS), a traditional herbal formula, has been indicated for the treatment of various skin disorders, including AD. This study investigated the effects of SPS on a 2,4-dinitrochlorobenzene- (DNCB-) induced AD mice model exposed to social isolation (SI) stress. The severity of the AD symptoms and behavioral abnormalities was evaluated. SPS reduced the clinical skin score as evaluated with the SCORing Atopic Dermatitis (SCORAD) index and suppressed the cutaneous infiltration of T-lymphocyte cells, mast cells, and eosinophils in SI-AD mice. The SPS treatment decreased the total distance and mean speed and increased resting time in the open field test (OFT) for these mice. In addition, the time spent in the social zone in the social interaction test also improved when SPS treatment was given. The levels of tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) in the prefrontal cortex (PFC) in the SI-AD mice were reduced by the oral administration of SPS. HaCaT and BV2 cells were used for the in vitro experiments. The pretreatment with SPS reduced the protein levels of the thymus and activation-regulated chemokine (TARC) and macrophage-derived chemokine (MDC) in the HaCaT cells stimulated with TNF-α and interferon-gamma (IFN-γ) (TI). SPS also suppressed TNF-α and IL-6 secretion in lipopolysaccharide- (LPS-) stimulated BV2 cells. These results imply that SPS could be a promising candidate for the treatment of AD in patients under stress conditions and at risk of exacerbation.

Psychological and biological resilience modulates the effects of stress on epigenetic aging

Our society is experiencing more stress than ever before, leading to both negative psychiatric and physical outcomes. Chronic stress is linked to negative long-term health consequences, raising the possibility that stress is related to accelerated aging. In this study, we examine whether resilience factors affect stress-associated biological age acceleration. Recently developed "epigenetic clocks" such as GrimAge have shown utility in predicting biological age and mortality. Here, we assessed the impact of cumulative stress, stress physiology, and resilience on accelerated aging in a community sample (N = 444). Cumulative stress was associated with accelerated GrimAge (P = 0.0388) and stress-related physiologic measures of adrenal sensitivity (Cortisol/ACTH ratio) and insulin resistance (HOMA). After controlling for demographic and behavioral factors, HOMA correlated with accelerated GrimAge (P = 0.0186). Remarkably, psychological resilience factors of emotion regulation and self-control moderated these relationships. Emotion regulation moderated the association between stress and aging (P = 8.82e-4) such that with worse emotion regulation, there was greater stress-related age acceleration, while stronger emotion regulation prevented any significant effect of stress on GrimAge. Self-control moderated the relationship between stress and insulin resistance (P = 0.00732), with high self-control blunting this relationship. In the final model, in those with poor emotion regulation, cumulative stress continued to predict additional GrimAge Acceleration even while accounting for demographic, physiologic, and behavioral covariates. These results demonstrate that cumulative stress is associated with epigenetic aging in a healthy population, and these associations are modified by biobehavioral resilience factors.

Ethanol intake in male mice exposed to social defeat: Environmental enrichment potentiates resilience

Large preclinical evidence shows that exposure to social defeat (SD) increases vulnerability to drug abuse, increasing the consumption of ethanol. However, not all subjects are equally affected by the changes induced by stress. Previous reports have evidenced that the resilient phenotype to depressive-like behaviors after SD is associated with the resistant phenotype to cocaine-increased rewarding effects and the smaller neuroinflammatory response. The aim of the present study was to further clarify whether the resilient profile to depressive-like behavior also predicts a protection against the increase in ethanol intake induced by SD. The neuroinflammatory profile was studied after the end of the oral ethanol self-administration (SA) procedure, measuring levels of the pro-inflammatory cytokine IL-6 and the chemokine CX3CL1 or fractalkine in the striatum and prefrontal cortex. Previous studies have shown that environmental enrichment (EE) is an effective mechanism to dimish the detrimental effects of social stress. In a second study, we aimed to evaluate if EE housing before exposure to SD could potentiate resilience. Our results showed that mice with a phenotype susceptible to SD-induced depressive-like behaviors showed increased ethanol consumption and increased neuroinflammatory signaling. In contrast, despite the lack of effect on depressive-like behaviors, defeated mice previously housed under EE conditions did not show an increase in ethanol SA or an increase in immune response. To sum up, the resilient phenotype to SD develops at different levels, such as depressive-like behaviors, ethanol consumption and the neuroinflammatory response. Our results also point to the protective role of EE in potentiating resilience to SD effects.

Implementing Home Office Work at a Large Psychiatric University Hospital in Switzerland During the COVID-19 Pandemic: Field Report

BACKGROUND

During the COVID-19 pandemic in 2020, psychiatric hospitals all over the world had to adapt their services to the prevailing governmental regulations. As a consequence, home office use and telepsychiatry boomed.

OBJECTIVE

The purpose of this study was to evaluate the potential of home office use, its adoption, and the association of home office use with employees' mental health in a large psychiatric university hospital in Switzerland.

METHODS

We obtained and analyzed home office implementation and use data from the psychiatric university hospital's information technology services. We also conducted a cross-sectional web-based survey to assess the employees' attitudes toward the clinic's crisis management during the COVID-19 pandemic in early 2020. Part of this web-based survey consisted of questions about home office use between March and June 2020, attitudes toward home office implementation, and mental health. Three mental health measures assessed depressive symptoms (Patient Health Questionnaire [PHQ]-2), anxiety (General Anxiety Disorder [GAD]-2), and stress factors (stress module of the PHQ-D); a cut-off score ≥3 was used for the PHQ-2 and GAD-2.

RESULTS

Of the 200 participating employees, 69 reported that they had worked from home at least partially (34.5%). Home office use differed significantly across professional groups (χ₁₆²=72.72, P≤.001, n=200). Employees experienced neither depressive symptoms (mean 0.76, SD 1.14) nor anxiety (mean 0.70, SD 1.03). The employees reported minor psychosocial stressors (mean 2.83, SD 2.92). The number of reported stress factors varied significantly across groups with different levels of home office use (χ₄²=9.72, P=.04).

CONCLUSIONS

In general, home office implementation appears to be feasible for large psychiatric hospitals, however, it is not equally feasible for all professional groups. Professional groups that require personal contact with patients and technical or manual tasks must work onsite. Further evaluation of home office use in psychiatric hospitals up to the development of clinics that function merely online will follow in future research. The situation created by the COVID-19 pandemic served as a stepping stone to promote home office use and should be used to improve employees' work-life balance, to save employers costs and foster other benefits.

Decreased kynurenine pathway potentiate resilience to social defeat effect on cocaine reward

The kynurenine (KYN) pathway of tryptophan (TRP) degradation is activated by stress and inflammatory factors. It is now well established that social stress induces the activation of the immune system, with central inflammation and KYN metabolism being two of the main factors linking stress with depression. The aim of the present study was to evaluate the long-lasting changes in the KYN pathway induced by social defeat (SD) associated with the resilience or susceptibility to an increase in the conditioned rewarding effects of cocaine. Mice were exposed to repeated SD and 3 weeks later, a conditioned place preference (CPP) induced by a subthreshold dose of cocaine (1.5 mg/kg) was developed. KYN levels in plasma, cerebellum, hippocampus, striatum and limbic forebrain were studied at the end of the CPP procedure. Changes in the KYN pathway after exposure to pharmacological (oxytocin and indomethacin) and environmental interventions (environmental enrichment) were also evaluated. Our results showed that defeated susceptible (SD-S) mice had higher conditioning scores than resilient mice (SD-R). In addition, although KYN concentration was elevated in all defeated mice, SD-R mice showed smaller increases in KYN concentration in the cerebellum than SD-S mice. Oxytocin or Indomethacin treatment before SD normalized cocaine-induced CPP, although the increase in the KYN pathway was maintained. However, environmental enrichment before SD normalized cocaine-induced CPP and prevented the increase in the KYN pathway. The present study highlights the role of the KYN pathway and anti-inflammatory drugs acting on TRP metabolism as pharmacological targets to potentiate resilience to social stress effects.

Social Needs, Chronic Conditions, and Health Care Utilization among Medicaid Beneficiaries

Health care organizations are increasingly assessing patients' social needs (eg, food, utilities, transportation) using various measures and methods. Prior studies have assessed social needs at the point of care and many studies have focused on correlates of 1 specific need (eg, food). This comprehensive study examined multiple social needs and medical and pharmacy claims data. Medicaid beneficiaries in Louisiana (n = 10,275) completed a self-report assessment of 10 social needs during July 2018 to June 2019. Chronic health conditions, unique medications, and health care utilization were coded from claims data. The sample was predominantly female (72%), Black (45%) or White (32%), had a mean age of 42 years, and at least 1 social need (55%). In bivariate analyses, having greater social needs was associated with greater comorbidity across conditions, and each social need was consistently associated with mental health and substance use disorders. In multivariable logistic analyses, having ≥2 social needs was positively associated with emergency department (ED) visits (OR = 1.39, CI = 1.23 - 1.57) and negatively associated with wellness visits (OR = 0.87, CI = 0.77 - 0.98), inpatient visits (OR = 0.87, CI = 0.76 - 0.99), and 30-day rehospitalization (OR = 0.66, CI = 0.50 - 0.87). Findings highlight the greater concomitant risk of social needs, mental health, and substance use. Admission policies may reduce the impact of social needs on hospitalization. Chronic disease management programs offered by health plans may benefit from systematically assessing and addressing social needs outside point-of-care interactions to impact health outcomes and ED utilization. Behavioral health care management programs would benefit from integrating interventions for multiple social needs.

Do Japan's Health Care Personnel Meet the Personal Health Goals of the "National Health Promotion Program"?

To improve health among the population and reduce the societal burden of care and health-related costs in a rapidly aging environment, the Japanese government launched the "National Health Promotion Program in the 21st Century" (HJ21), which contains goals concerning areas such as lifestyle behavior and the use of preventive medicine. While health care personnel are responsible for guiding others' health choices, they may not maintain healthy lifestyles themselves. Whether these individuals are meeting the HJ21 goals has not yet been examined. This study aims to determine whether certified specialists in health management are meeting such goals, and to compare their performance with the national average. This is a cross-sectional survey study. Study participants, sourced from all prefectures in Japan, were specialists certified in health management. We measured data concerning demographic information, lifestyle (physical activity, nutrition, diet, sleep, rest, smoking, and alcohol use), and the use of preventive medicine. The study participants exhibited many characteristics of high health literacy. They had an overall healthy lifestyle and met most of the HJ21 goals of healthy lifestyle, and a high proportion underwent health maintenance examinations and cancer screenings. These practices and behaviors maybe associated with high health literacy and social engagement activities.

Distinct latent profiles based on neurobehavioural, physical and psychosocial functioning of former National Football League (NFL) players: an NFL-LONG Study

OBJECTIVE

To identify subgroups of former National Football League (NFL) players using latent profile analysis (LPA) and examine their associations with total years of participation (TYP) and self-reported lifetime sport-related concussion history (SR-CHx).

METHODS

Former NFL players (N=686) aged 50-70 years, with an average 18.0 TYP (±4.5) completed a questionnaire. SR-CHx distributions included: low (0-3; n=221); intermediate (4-8; n=209) and high (9+; n=256). LPA measures included: Quality of Life in Neurological Disorders Emotional-Behavioral Dyscontrol, Patient Reported Outcomes Measurement Information System Cognitive Function, Emotional Support, Self-Efficacy, Meaning and Purpose, Physical Function, Pain Interference, Participation in Social Roles and Activities, Anxiety, Depression, Fatigue, and Sleep Disturbance. Demographic, medical/psychiatric history, current psychosocial stressors, TYP and SR-CHx were compared across latent profiles (LPs).

RESULTS

A five profile solution emerged: (LP1) global higher functioning (GHF; 26.5%); (LP2) average functioning (10.2%); (LP3) mild somatic (pain and physical functioning) concerns (22.0%); (LP4) somatic and cognitive difficulties with mild anxiety (SCA; 27.5%); LP5) global impaired functioning (GIF; 13.8%). The GIF and SCA groups reported the largest number ofe- medical/psychiatric conditions and higher psychosocial stressor levels. SR-CHx was associated with profile group (χ²(8)=100.38, p<0.001); with a higher proportion of GIF (72.6%) and SCA (43.1%) groups reporting being in the high SR-CHx category, compared with GHF (23.1%), average (31.4%) and somatic (27.8%) groups. TYP was not significantly associated with group (p=0.06), with greater TYP reported by the GHF group.

CONCLUSIONS

Five distinct profiles of self-reported functioning were identified among former NFL players. Several comorbid factors (ie, medical/psychiatric diagnoses and psychosocial stressors) and SR-CHx were associated with greater neurobehavioural and psychosocial dysfunction.

Psychosocial Functioning, BMI, and Nutritional Behaviors in Women at Cardiovascular Risk

Psychosocial factors such as depression, anxiety, and stress are associated with increased cardiovascular risk. Health behaviors may play a role in this relationship, as individuals experiencing elevated levels of anxiety, stress, and/or depression may be less likely to engage in risk-reducing behaviors such as diet and exercise. Some evidence suggests that this relationship is particularly relevant for women. This study explored the relationship between levels of anxiety, depression, stress, and specific nutritional behaviors in a sample of 187 women at cardiovascular risk. BMI was explored as a possible moderator of these relationships. Higher levels of depression in patients with high BMI was associated with increased fruit consumption, whereas this was not seen in highly depressed patients with normal BMI. The reverse pattern was seen for consumption of sweet drinks. Anxiety was found to have a complex relationship with consumption of sweetened drinks and white bread, with higher consumption at moderately elevated levels of anxiety and reduced consumption at the highest levels. Possible interpretations of these findings, as well as their implications for lifestyle interventions with this population are discussed. These findings suggest a number of questions for further research.

Voluntary wheel running protects against the increase in ethanol consumption induced by social stress in mice

Previous studies have shown that exposure to social defeat (SD), a model of social stress, produces a long-term increase in the consumption of ethanol, most likely through an increase in the neuroinflammation response. The aim of the present study was to evaluate whether exposure to physical activity in the form of voluntary wheel running (VWR) could block the increase in ethanol consumption and the neuroinflammatory response induced by social stress. Mice were exposed to either 4 sessions of repeated social defeat (RSD) or a non-stressful experience. During the whole procedure, half of the mice were exposed to controlled physical activity, being allowed 1 h access to a low-profile running wheel three times a week. Three weeks after the last RSD, animals started the oral self-administration (SA) of ethanol (6% EtOH) procedure. Biological samples were taken 4 h after the first and the fourth RSD, 3 weeks after the last RSD, and after the SA procedure. Brain tissue (striatum) was used to determine protein levels of the chemokines fractalkine (CX3CL1) and SDF-1 (CXCL12). RSD induced an increase in ethanol consumption and caused greater motivation to obtain ethanol. The striatal levels of CX3CL1 and CXCL12 were also increased after the last RSD. VWR was able to reverse the increase in ethanol intake induced by social stress and the neuroinflammatory response. In conclusion, our results suggest that VWR could be a promising tool to prevent and reduce the detrimental effects induced by social stress.
