Prevalence and validity of ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD: A population-based survey of Hong Kong adults

The present study aimed to report the prevalence of ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) in the general adult Hong Kong population, and examine the validity of the Chinese International Trauma Questionnaire (ITQ). This descriptive cross-sectional population-based telephone survey included a representative sample of 1070 non-institutionalized permanent Hong Kong residents ages 18–64 years. Participants provided responses to the Chinese version of the ITQ, and measures of adverse childhood experiences (ACEs), depression, anxiety, and stress. Based on the diagnostic algorithm of the ITQ, 5.9% of the sample screened positive for either CPTSD or PTSD, with CPTSD (4.2%) being more common that PTSD (1.7%). Results of the confirmatory factor analysis indicated the first-order correlated 6-factor model to be the best fitting solution. Symptom cluster summed scores were all positively and significantly correlated with all criterion variables. This investigation established the prevalence rates of ICD-11 PTSD and CPTSD using a general adult population sample in Hong Kong. The Chinese ITQ demonstrated sound factorial validity and concurrent validity. Future research can further characterize ICD-11 PTSD and CPTSD in subgroups using the Chinese ITQ.

Testing the Psychometric Properties of 9 Bolt-Ons for the EQ-5D-5L in a General Population Sample

ObjectivesWe aimed to assess the psychometric performance and added value of 9 existing bolt-ons (breathing problems, cognition, hearing, self-confidence, skin irritation, sleep, social relationships, tiredness, and vision) for the EQ-5D-5L in a general population sample. MethodsThe EQ-5D-5L, 9 bolt-ons, SF-6Dv1, Patient-Reported Outcomes Measurement Information System (PROMIS)-29 + 2, PROMIS Global Health, and Satisfaction with Life Scale were completed in an online cross-sectional survey among a general adult population sample in Hungary (n = 1587). The following psychometric properties were tested for the EQ-5D-5L + bolt-on(s): ceiling, divergent and convergent validity, structural validity, known-group validity, and explanatory power. ResultsAdding sleep (30%), tiredness (24%), or vision (21%) substantially reduced the ceiling of the EQ-5D-5L (41%). Cognition, sleep, social relationships, and tiredness correlated with corresponding PROMIS and SF-6D items (rs = ǀ0.32ǀ − ǀ0.73ǀ). All bolt-ons, except cognition and self-confidence, loaded on a different factor from the EQ-5D-5L dimensions. Breathing, hearing, skin irritation, and vision significantly improved known-group validity in relevant health condition groups. The sleep bolt-on improved known-group validity in 9 of 13 chronic health conditions. Tiredness had the largest impact on explaining EQ VAS score variance in 8 of 13 conditions. Hearing and vision improved the ability of the EQ-5D-5L to capture declining health with age, whereas self-confidence and social relationships were valuable for mental health assessment. ConclusionsThis study established the validity of multiple bolt-ons for the EQ-5D-5L and highlights the usefulness of including relevant bolt-ons in population-based and patient surveys. Our findings inform the further development of these bolt-ons and the bolt-on item selection for clinical studies.

Population Norms for the EQ-5D-5L, PROPr and SF-6D in Hungary.

This study aimed to develop population norms for three preference-accompanied measures [EQ-5D-5L, Patient-Reported Outcomes Measurement Information System (PROMIS)-preference scoring system (PROPr) and Short-Form Six-Dimension (SF-6D)] in Hungary. In November 2020, an online cross-sectional survey was conducted among a representative sample of the Hungarian adult general population (n = 1631). Respondents completed the Hungarian versions of the EQ-5D-5L, PROMIS-29+2 version2.1 and 36-item Short Form Survey version 1 (SF-36v1). The association of utilities with sociodemographic and health-related characteristics of respondents was analysed using multivariate regressions. The proportion of respondents reporting problems ranged from 8 to 44% (self-care to pain/discomfort) on the EQ-5D-5L, 39-94% (physical function to sleep) on PROPr and 38-87% (role limitations to vitality) on the SF-6D. Problems related to physical function, self-care, usual activities/role limitations and pain increased with age, while mental health problems decreased in all three measures. In almost all corresponding domains, respondents indicated the fewest problems on the EQ-5D-5L and the most problems on the SF-6D. The mean EQ-5D-5L, PROPr and SF-6D utilities were 0.900, 0.535 and 0.755, respectively. Female gender (PROPr, SF-6D), a lower level of education (EQ-5D-5L, PROPr), being unemployed or a disability pensioner (EQ-5D-5L), being underweight or obese (SF-6D), lack of physical exercise (all) and polypharmacy (all) were associated with significantly lower utilities. PROPr yielded the lowest and EQ-5D-5L the highest mean utilities in 28 of 30 chronic health conditions. This study presents the first set of Hungarian population norms for the EQ-5D-5L, PROPr and SF-6D. Our findings can serve as reference values in clinical trials and observational studies and contribute to the monitoring of population health and the assessment of disease burden in Hungary.

Factors influencing olfactory function in an adult general population sample: the CHRIS study.

The sense of smell allows for the assessment of the chemical composition of volatiles in our environment. Different factors are associated with reduced olfactory function, including age, sex, as well as health and lifestyle conditions. However, most studies that aimed at identifying the variables that drive olfactory function in the population suffered from methodological weaknesses in study designs and participant selection, such as the inclusion of convenience sample or only of certain age groups, or recruitment biases. We aimed to overcome these issues by investigating the Cooperative Health Research in South Tyrol (CHRIS) cohort, a population-based cohort, by using a validated odor identification test. Specifically, we hypothesized that a series of medical, demographic and lifestyle variables is associated with odor identification abilities. In addition, our goal was to provide clinicians and researchers with normative values for the Sniffin' Sticks identification set, after exclusion of individuals with impaired nasal patency. We included 6,944 participants without acute nasal obstruction and assessed several biological, social, and medical parameters. A basic model determined that age, sex, years of education, and smoking status together explained roughly 13% of the total variance in the data. We further observed that variables related to medical (positive screening for cognitive impairment and for Parkinson's disease, history of skull fracture, stage 2 hypertension) and lifestyle (alcohol abstinence) conditions had a negative effect on odor identification scores. Finally, we provide clinicians with normative values for both versions of the Sniffin' Sticks odor identification test, i.e. with 16 items and with 12 items.

Behavior-related risk factors and time to death among persons with alcohol consumption versus persons without: A general population study with mortality follow-up after 20 years

BackgroundEvidence shows that low to moderate alcohol consumers seem to live longer than abstainers. Insufficient consideration of subgroups among abstainers and of further behavior-related risk factors for death might be reasons. The aim of this study was to compare alcohol lifetime abstainers, former drinkers, and current consumers with regard to mortality considering tobacco smoking, body overweight, and physical inactivity. MethodsA general adult population sample of residents aged 18 to 64 had been drawn at random in northern Germany. Among eligible persons, 4093 (70.2%) participated. Assessments included alcohol consumption by the Alcohol Use Disorders Identification Test Consumption in addition to lifetime alcohol abstinence and former drinking. A score of behavior-related risk factors was built from tobacco smoking, body overweight, and physical inactivity. Twenty years later, a mortality follow-up was conducted. Data of 4028 study participants were analyzed. ResultsAt baseline, former alcohol consumers but not current low to moderate alcohol drinkers had more behavior-related risk factors than lifetime abstainers. At follow-up, former alcohol drinkers with two or more behavior-related risk factors had a shorter time to death than lifetime abstainers with 0 or one behavior-related risk factor (hazard ratio 3.43, 95% confidence interval: 1.63–7.20). Low to moderate alcohol drinkers did not survive longer than lifetime alcohol abstainers with 0 or one behavior-related risk factor. ConclusionThe results provide evidence against the assumption that alcohol consumption has a beneficial effect on health and longevity.

The EORTC QLU-C10D: the Hong Kong valuation study.

The EORTC QLU-C10D is a new preference-based measure derived from the EORTC QLQ-C30. Country-specific value sets are required to support the cost-utility analysis of cancer-related interventions. This study aimed to generate an EORTC QLU-C10 value set for Hong Kong (HK). A HK online panel was quota-sampled to achieve an adult general population sample representative by sex and age. Participants were invited to complete an online discrete choice experiment survey. Each participant was asked to complete 16 choice-pairs, randomly assigned from a total of 960 choice-pairs, each comprising two QLU-C10D health states and a duration attribute. Conditional and mixed logistic regression analyses were used to analyse the data. The analysis included data from 1041 respondents who had successfully completed the online survey. The distribution of sex did not differ from that of the general population, but a significant difference was found among age groups. A weighting analysis for non-representative variable (age) was used. Utility decrements were generally monotonic, with the largest decrements for physical functioning (-0.308), role functioning (-0.165), and pain (-0.161). The mean QLU-C10D utility score of the participants was 0.804 (median = 0.838, worst to best = -0.169 to 1). The value of the worst health state was -0.223, which was sufficiently lower than 0 (being dead). This study established HK utility weights for the QLU-C10D, which can facilitate cost-utility analyses across cancer-related health programmes and technologies.

Cynical hostility increases whereas sense of coherence decreases the odds for current suicidal thoughts: A cross-sectional study of the general adult population sample.

Earlier, somatic diseases and mental disorders have been associated with cynical hostility as well as sense of coherence, but there is a gap of knowledge, whether they contribute to suicidality at population level. A random sample of adults, representative of the general population living in Finland, participated in a nationwide health examination study. For 4387 participants aged 18-97 years, we analyzed, after controlling for confounding factors, whether cynical hostility, as assessed with the 8-item Cook-Medley Hostility Scale, or sense of coherence, as assessed with the 13-item Sense of Coherence Scale, contributed to current suicidal thoughts during the past 7 days as scored on the 25-item Hopkins Symptom Checklist. Suicidal thoughts (current thoughts of ending one's life) were associated significantly with cynical hostility (p < 0.001) as well as with sense of coherence (p < 0.001). Of the specific items of cynical hostility, the item "I am sure that most people do not have problems with lying for their own good" was associated most strongly with current suicidal thoughts (p < 0.001). Cynical hostility predicted current suicidal thoughts in a population-based sample of adults aged 18-97 years. Sense of coherence protected from current suicidal thoughts.

Effects of Neighborhood Disconnection on Psychological Distress and Suicide Risk Associated with Interpersonal Violence Within Racial Groups.

Negative mental health outcomes have been associated with adverse childhood experiences (ACEs) and intimate partner violence (IPV); however, few studies have identified risk and protective factors across levels of the social ecology that mitigate the onset of psychological distress and suicide risk associated with trauma. This study examines the relationship between ACEs, IPV, and mental health (i.e., psychological distress, suicidal ideation, and suicide attempts) within racial sub-populations of Black American, Latinx, and White adults.An online, cross-section survey was administered to a general population sample of adults in Baltimore and New York City. ACEs, IPV, and mental health outcomes were assessed within racial sub-populations of Black American (N = 390), Latinx (N = 178), and White (N = 339) adults, while accounting for within-group demographic differences. Moderating effects of social support and neighborhood disconnection on the relationship between ACEs, IPV, and mental health outcomes were also assessed.IPV was associated with psychological distress and suicidal ideation for Black and Latinx adults, but not for White adults. ACEs were associated with increased psychological distress for all three groups, and increased odds for suicidal ideation among Black and Latinx adults.. A significant negative interaction effect for neighborhood disconnection was found in the relationship between ACEs and psychological distress for Black adults.Findings highlight the significant mental health burdens of ACEs and IPV within racial and ethnic groups. Neighborhood disconnection may exacerbate psychological distress associated with ACEs among populations most impacted by interpersonal violence and mental health inequalities.

A head-to-head comparison of the EQ-5D-5L and 15D descriptive systems and index values in a general population sample

BackgroundThe EQ-5D-5L and 15D are generic preference-accompanied health status measures with similar dimensions. In this study, we aim to compare the measurement properties of the EQ-5D-5L and 15D descriptive systems and index values in a general population sample.MethodsIn August 2021, an online cross-sectional survey was conducted in a representative adult general population sample (n = 1887). The EQ-5D-5L and 15D descriptive systems and index values were compared in terms of ceiling and floor, informativity (Shannon’s Evenness index), agreement, convergent and known-groups validity for 41 chronic physical and mental health conditions. Danish value sets were used to compute index values for both instruments. As a sensitivity analysis, index values were also estimated using the Hungarian EQ-5D-5L and Norwegian 15D value sets.ResultsOverall, 270 (8.6%) and 1030 (3.4*10−6%) unique profiles occurred on the EQ-5D-5L and 15D. The EQ-5D-5L dimensions (0.51–0.70) demonstrated better informativity than those of 15D (0.44–0.69). EQ-5D-5L and 15D dimensions capturing similar areas of health showed moderate or strong correlations (0.558–0.690). The vision, hearing, eating, speech, excretion and mental function 15D dimensions demonstrated very weak or weak correlations with all EQ-5D-5L dimensions, which may indicate potential room for EQ-5D-5L bolt-ons. The 15D index values showed lower ceiling than the EQ-5D-5L (21% vs. 36%). The mean index values were 0.86 for the Danish EQ-5D-5L, 0.87 for the Hungarian EQ-5D-5L, 0.91 for the Danish 15D and 0.81 for the Norwegian 15D. Strong correlations were found between the index values (Danish EQ-5D-5L vs. Danish 15D 0.671, Hungarian EQ-5D-5L vs. Norwegian 15D 0.638). Both instruments were able to discriminate between all chronic condition groups with moderate or large effect sizes (Danish EQ-5D-5L 0.688–3.810, Hungarian EQ-5D-5L 1.233–4.360, Danish 15D 0.623–3.018 and Norwegian 15D 1.064–3.816). Compared to the 15D, effect sizes were larger for the EQ-5D-5L in 88–93% of chronic condition groups.ConclusionsThis is the first study to compare the measurement properties of the EQ-5D-5L and 15D in a general population sample. Despite having 10 fewer dimensions, the EQ-5D-5L performed better than the 15D in many aspects. Our findings help to understand the differences between generic preference-accompanied measures and support resource allocation decisions.

Hungarian PROMIS-29+2: psychometric properties and population reference values

ObjectivesThis study aims to assess psychometric properties of the Hungarian PROMIS-29+2 profile measure and provide general population reference values for Hungary.MethodsAn adult general population sample (n = 1700) completed PROMIS-29+2 v2.1 in an online survey. The following psychometric properties were assessed: floor and ceiling effect, convergent validity with SF-36v1 domains, internal consistency (McDonald’s omega), unidimensionality, local independence, monotonicity, graded response model (GRM) fit and differential item functioning (DIF). Age- and gender-specific reference values were established using the US item calibrations.ResultsDepending on scale orientation, high floor or ceiling effects were observed for all domains (25.2–60.7%) except for sleep disturbance. McDonald’s omega for domains ranged from 0.87–0.97. Unidimensionality, local independence and monotonicity were supported and the GRM adequately fitted for all but one domains. The sleep disturbance domain demonstrated item misfit, response level disordering and low discrimination ability, particularly for item Sleep116 (‘refreshing sleep’). Strong correlations were observed between PROMIS-29+2 and corresponding SF-36 domains (rs=│0.60│ to │0.78│). No DIF was detected for most sociodemographic characteristics. Problems with physical function, pain interference and social roles tended to increase, whereas problems with anxiety, depression, fatigue and cognitive function declined with age (p < 0.01). In all domains except for cognitive function, more health problems occurred in females than in males (p < 0.001).ConclusionThe Hungarian PROMIS-29+2 shows satisfactory psychometric properties; however, the sleep disturbance domain substantially underperforms that requires further attention. Population reference values were generated that facilitate the interpretation of health outcomes in various patient populations.

The Alcohol Use Disorders Identification Test and Mortality 20 Years later

Abstract The objective was to test whether Alcohol Use Disorders Identification Test (AUDIT) results may predict mortality after 20 years. An observational study was conducted. It included an interview of a general population sample aged 18 to 64 in northern Germany in the years 1996 − 1997 (baseline) and a mortality-follow-up in the years 2017 − 2018. Study participants were 3581 persons who had consumed alcohol during the last 12 months prior to the baseline assessment. It included the AUDIT which was filled in by study participants. At follow-up, death cases were ascertained including the date of death. Official records and death certificates from local health authorities were used. Cox proportional hazards regression revealed that the AUDIT predicted time to death. The hazard ratio was 1.70 (95% confidence interval: 1.43 − 2.02) with the lowest AUDIT zone of values as the reference group. Competing risks regression analysis for diagnosis-specific mortality data revealed that the AUDIT predicted cardiovascular mortality (subhazard ratio, 1.84; 95% confidence interval, 1.49 − 2.27). It is concluded that the alcohol screening predicted total and cardiovascular mortality in this adult general population sample.

Attention-deficit hyperactivity disorder traits are a more important predictor of internalising problems than autistic traits

Autism Spectrum Disorder (ASD) and Attention-Deficit Hyperactivity Disorder (ADHD) are both linked to internalising problems like anxiety and depression. ASD and ADHD also often co-occur, making their individual statistical contributions to internalising disorders difficult to investigate. To address this issue, we explored the unique associations of self-reported ASD traits and ADHD traits with internalising problems using a large general population sample of adults from the United Kingdom (N = 504, 49% male). Classical regression analyses indicated that both ASD traits and ADHD traits were uniquely associated with internalising problems. Dominance and Bayesian analyses confirmed that ADHD traits were a stronger, more important predictor of internalising problems. However, brief depression and anxiety measures may not provide a comprehensive index of internalising problems. Additionally, we focused on recruiting a sample that was representative of the UK population according to age and sex, but not ethnicity, a variable that may be linked to internalising disorders. Nevertheless, our findings indicate that while ASD and ADHD uniquely predict internalising problems, ADHD traits are a more important statistical predictor than ASD traits. We discuss potential mechanisms underlying this pattern of results and the implications for research and clinical practice concerning neurodevelopmental conditions.

Disentangling the impact of childhood abuse and neglect on depressive affect in adulthood: A machine learning approach in a general population sample

BackgroundDifferent types of childhood maltreatment (CM) are key risk factors for psychopathology. Specifically, there is evidence for a unique role of emotional abuse in affective psychopathology in children and youth; however, its predictive power for depressive symptomatology in adulthood is still unknown. Additionally, emotional abuse encompasses several facets, but the strength of their individual contribution to depressive affect has not been examined. MethodHere, we used a machine learning (ML) approach based on Random Forests to assess the performance of domain scores and individual items from the Childhood Trauma Questionnaire (CTQ) in predicting self-reported levels of depressive affect in an adult general population sample. Models were generated in a training sample (N = 769) and validated in an independent test sample (N = 466). Using state-of-the-art methods from interpretable ML, we identified the most predictive domains and facets of CM for adult depressive affect. ResultsModels based on individual CM items explained more variance in the independent test sample than models based on CM domain scores (R2 = 7.6 % vs. 6.4 %). Emotional abuse, particularly its more subjective components such as reactions to and appraisal of the abuse, emerged as the strongest predictors of adult depressive affect. LimitationsAssessment of CM was retrospective and lacked information on timing and duration. Moreover, reported rates of CM and depressive affect were comparatively low. ConclusionsOur findings corroborate the strong role of subjective experience in CM-related psychopathology across the lifespan that necessitates greater attention in research, policy, and clinical practice.

Severity of alcohol dependence and mortality after 20years in an adult general population sample.

ObjectivesTo estimate mortality on grounds of the severity of alcohol dependence which has been assessed by two approaches: the frequency of alcohol dependence symptoms (FADS) and the number of alcohol dependence criteria (NADC).MethodsA random sample of adult community residents in northern Germany at age 18 to 64 had been interviewed in 1996. Among 4075 study participants at baseline, for 4028 vital status was ascertained 20 years later. The FADS was assessed by the Severity of Alcohol Dependence Scale among the 780 study participants who had one or more symptoms of alcohol dependence or abuse and vital status information. The NADC was estimated by the Munich Composite International Diagnostic Interview among 4028 study participants with vital status information. Cox proportional hazard models were used.ResultsThe age‐adjusted hazard ratio for the FADS (value range: 0–79) was 1.02 (95% confidence interval, CI: 1.016–1.028), for the NADC (value range: 0–7) it was 1.25 (CI: 1.19–1.32).ConclusionsThe FADS and NADC predicted time to death in a dose‐dependent manner in this adult general population sample.

The physical activity health paradox and risk factors for cardiovascular disease: A cross-sectional compositional data analysis in the Copenhagen City Heart Study.

Studies indicate that physical activity during leisure and work have opposite associations with cardiovascular disease (CVD) risk factors, referred to as the physical activity health paradox. We investigated how sedentary behaviour and physical activity types during leisure and work are associated with systolic blood pressure (SBP), waist circumference (WC), and low-density lipoprotein cholesterol (LDL-C) in an adult general population sample using compositional data analysis. Participants wore accelerometers for 7 days (right thigh and iliac crest; 24 h/day) and had their SBP, WC, and LDL-C measured. Accelerometer data was analysed using the software Acti4 to derive daily time spent in sedentary behaviour and physical activity types. The measure of association was quantified by reallocating time between sedentary behaviour and 1) walking, and 2) high-intensity physical activity (HIPA; sum of climbing stairs, running, cycling, and rowing), during both domains. In total, 652 participants were included in the analyses (median wear time: 6 days, 23.8 h/day). During leisure, the results indicated that less sedentary behaviour and more walking or more HIPA was associated with lower SBP, while during work, the findings indicated an association with higher SBP. During both domains, the findings indicated that less sedentary behaviour and more HIPA was associated with a smaller WC and lower LDL-C. However, the findings indicated less sedentary behaviour and more walking to be associated with a larger WC and higher LDL-C, regardless of domain. During leisure, less sedentary behaviour and more walking or HIPA seems to be associated with a lower SBP, but, during work, it seems to be associated with a higher SBP. No consistent differences between domains were observed for WC and LDL-C. These findings highlight the importance of considering the physical activity health paradox, at least for some risk factors for CVD.

Symptom Patterns of the Occurrence of Depression and Anxiety in a Japanese General Adult Population Sample: A Latent Class Analysis.

BackgroundGiven the high comorbidity and shared risk factors between depression and anxiety, whether they represent theoretically distinct disease entities or are just characteristics of a common negative affect dimension remains debated. Employing a data-driven and person-centered approach, the present study aims to identify meaningful and discrete symptom patterns of the occurrence of depression and anxiety.MethodsUsing data from an adult sample from the Japanese general population (n = 403, including 184 females, age = 42.28 ± 11.87 years), we applied latent class analysis to identify distinct symptom patterns of depression (PHQ-9) and anxiety (STAI Y1). To empirically validate the derived class memberships, we tested the association between the derived classes and personal profiles including childhood experiences, life events, and personality traits.ResultsThe best-fitting solution had four distinct symptom patterns or classes. Whereas both Class 1 and 2 had high depression, Class 1 showed high anxiety due to high anxiety-present symptoms (e.g., “I feel nervous”) while Class 2 showed moderate anxiety due to few anxiety-absent symptoms (e.g., “I feel calm”). Class 3 manifested mild anxiety symptoms due to lacking responses on anxiety-absent items. Class 4 manifested the least depressive and anxiety-present symptoms as well as the most anxiety-absent symptoms. Importantly, whereas both Class 1 and 2 had higher childhood neglect and reduced reward responsiveness, etc. compared to Class 4 (i.e., the most healthy class), only Class 1 had greater negative affect and reported more negative life events.ConclusionsTo our knowledge, this is the first latent class analysis that examined the symptom patterns of depression and anxiety in Asian subjects. The classes we identified have distinct features that confirm their unique patterns of symptom endorsement. Our findings may provide insights into the etiology of depression, anxiety, and their comorbidity.

Impulsivity and compulsivity as parallel mediators of emotion dysregulation in eating‐related addictive‐like behaviors, alcohol use, and compulsive exercise

IntroductionTransdiagnostically relevant psychological traits associated with psychiatric disorders are increasingly being researched, notably in substance use and addictive behaviors. We investigated whether emotion dysregulation mediated by impulsivity and/or compulsivity could explain variance in binge eating, food addiction, self‐starvation, and compulsive exercise, as well as alcohol use (addictive‐like behaviors relevant to the obesity and eating disorder fields).MethodA general population sample of adults (N = 500, mean age = 32.5 years), females (n = 376) and males (n = 124), completed the Difficulties in Emotion Regulation Scale‐16, the Trait Rash Impulsivity Scale, the Obsessive‐Compulsive Inventory—Revised, the Eating Disorders Examination Questionnaire, the Self‐Starvation Scale, the Exercise Dependence Scale, the Yale Food Addiction Scale, and the Alcohol Use Disorders Identification Test online. Besides gender comparisons and intercorrelations between measures, we used predefined multiple mediation models with emotion dysregulation as independent variable, impulsivity and compulsivity as parallel mediators, to investigate whether these factors contributed explanatory power to each addictive‐like behavior as outcome, also using age and body mass index as covariates.ResultsFemales scored higher than males on emotion dysregulation and the eating‐related addictive‐like behaviors food addiction, self‐starvation, and binge eating. Intercorrelations between measures showed that emotion dysregulation and compulsivity were associated with all outcome variables, impulsivity with all except compulsive exercise, and the eating‐related behaviors intercorrelated strongly. Mediation models showed full or partial mediation of emotion dysregulation for all behaviors, especially via compulsivity, suggesting a behavior‐specific pattern. Mediation models were not affected by age or gender.DiscussionAddictive‐like behaviors seemed to be maintained by trait levels of emotion dysregulation, albeit channeled via trait levels of compulsivity and/or impulsivity. The role of emotion dysregulation may help us to understand why addictive‐like behaviors can be difficult to change in both clinical and nonclinical groups, and may be informative for treatment‐planning in patients where these behaviors are present. Our findings support adopting a more dimensional approach to psychiatric classification by focusing psychological facets such as those studied.

Urban grey spaces are associated with increased allergy in the general population

Backgroundthe built environment in urban areas may have side effects on children's respiratory health, whilst less is known for adulthood. Aimto assess the association between increasing exposure to grey spaces and allergic status in an adult general population sample. Methods2070 subjects (age range 15–84 yrs), living in Pisa/Cascina, Italy, were investigated in 1991–93 through a questionnaire on health status and risk factors, skin prick test (SPT), serum Immunoglobulins E (IgE), and serum antibodies to benzo(a)pyrene diol epoxide (BPDE)-DNA adducts.Land-cover exposure within a 1000 m buffer from each subject's home address was assessed through the CORINE Land Cover program (CLC 1990) within the FP7/HEALS project (2013–2018). Participants' residential addresses were geocoded and the proportion of surrounding grey spaces was calculated.Through logistic regression models, adjusting for potential confounding factors, the effect of a 10% increase in grey spaces exposure on allergic biomarkers/conditions was assessed; the relationship with serum antibodies to BPDE-DNA adducts positivity was also analyzed. ResultsA 10% increase in grey spaces coverage was associated with a higher probability of having SPT positivity (OR 1.07, 95% CI 1.02-1.13), seasonal SPT positivity (OR 1.12, 1.05-1.19), polysensitization (OR 1.11, 1.04-1.19), allergic rhinitis (OR 1.10, 1.04-1.17), co-presence of SPT positivity and asthma/allergic rhinitis (OR 1.16, 1.08-1.25), asthma/allergic rhinitis (OR 1.06, 1.00-1.12), presence of serum antibodies to BPDE-DNA adducts positivity (OR 1.07, 1.01-1.14). Conclusionsgrey spaces have adverse effects on allergic status and are related to a biomarker of polycyclic aromatic hydrocarbons exposure in adulthood. Thus, they may be used as a proxy of urban environmental exposure.

Alcohol abstinence and mortality in a general population sample of adults in Germany: A cohort study.

BackgroundEvidence suggests that people who abstain from alcohol have a higher mortality rate than those who drink low to moderate amounts. However, little is known about factors that might be causal for this finding. The objective was to analyze former alcohol or drug use disorders, risky drinking, tobacco smoking, and fair to poor health among persons who reported abstinence from alcohol drinking in the last 12 months before baseline in relation to total, cardiovascular, and cancer mortality 20 years later.Methods and findingsA sample of residents aged 18 to 64 years had been drawn at random among the general population in northern Germany and a standardized interview conducted in the years 1996 to 1997. The baseline assessment included 4,093 persons (70.2% of those who had been eligible). Vital status and death certificate data were retrieved in the years 2017 and 2018.We found that among the alcohol-abstinent study participants at baseline (447), there were 405 (90.60%) former alcohol consumers. Of the abstainers, 322 (72.04%) had met one or more criteria for former alcohol or drug dependence or abuse, alcohol risky drinking, or had tried to cut down or to stop drinking, were daily smokers, or self-rated their health as fair to poor. Among the abstainers with one or more of these risk factors, 114 (35.40%) had an alcohol use disorder or risky alcohol consumption in their history. Another 161 (50.00%) did not have such an alcohol-related risk but were daily smokers. The 322 alcohol-abstinent study participants with one or more of the risk factors had a shorter time to death than those with low to moderate alcohol consumption. The Cox proportional hazard ratio (HR) was 2.44 (95% confidence interval (CI), 1.68 to 3.56) for persons who had one or more criteria for an alcohol or drug use disorder fulfilled in their history and after adjustment for age and sex. The 125 alcohol-abstinent persons without these risk factors (27.96% of the abstainers) did not show a statistically significant difference from low to moderate alcohol consumers in total, cardiovascular, and cancer mortality. Those who had stayed alcohol abstinent throughout their life before (42; 9.40% of the alcohol-abstinent study participants at baseline) had an HR 1.64 (CI 0.72 to 3.77) compared to low to moderate alcohol consumers after adjustment for age, sex, and tobacco smoking. Main limitations of this study include its reliance on self-reported data at baseline and the fact that only tobacco smoking was analyzed as a risky behavior alongside alcohol consumption.ConclusionsThe majority of the alcohol abstainers at baseline were former alcohol consumers and had risk factors that increased the likelihood of early death. Former alcohol use disorders, risky alcohol drinking, ever having smoked tobacco daily, and fair to poor health were associated with early death among alcohol abstainers. Those without an obvious history of these risk factors had a life expectancy similar to that of low to moderate alcohol consumers. The findings speak against recommendations to drink alcohol for health reasons.
