Well-being spectrum traits are associated with polygenic scores for autism.

Individuals with autism spectrum disorder (ASD) tend to experience lower well-being as demonstrated mostly for children and adolescents in epidemiological studies. A further investigation of inclusive well-being, in terms of five well-being spectrum (5-WBS) traits including neuroticism, depression, loneliness, life satisfaction, and positive affect, among adults with ASD may deepen our understanding of their well-being, and lead to the possibility to further modify societal supportive mechanisms for individuals with ASD. This study aims to investigate if a genetic predisposition for ASD is associated with 5-WBS traits using polygenic risk score (PRS) analysis. PRS for ASD were calculated based on the latest genome-wide association study of ASD by the Psychiatric Genetics Consortium (18,381 cases, 27,969 controls) and were created in the independent cohort UK Biobank. Regression analyses were performed to investigate the association between ASD PRS and 5-WBS traits in the UK Biobank population including 337,423 individuals. ASD PRS were significantly associated with all 5-WBS traits, showing a positive association with the negative WBS traits, neuroticism (max R2 = 0.04%, p < 1 × 10-4 ), depression (max R2 = 0.06%, p < 1 × 10-4 ), loneliness (max R2 = 0.04%, p < 1 × 10-4 ), and a negative association with the positive WBS traits, life satisfaction (max R2 = 0.08%, p < 1 × 10-4 ), positive affect (max R2 = 0.10%, p < 1 × 10-4 ). The findings suggest that adults carrying a high load of risk single nucleotide peptides (SNPs) for ASD are more likely to report decreased well-being. The study demonstrates a considerable connection between susceptibility to ASD, its underlying genetic etiology and well-being.

Job satisfaction has differential associations with delay discounting and risk-taking.

Low job satisfaction has been associated with both negative health and negative organizational outcomes. Knowledge on which factors influence job satisfaction remains limited. This study assesses the associations between job satisfaction and three personality traits related to cognitive- and inhibitory control: delay discounting, risk-taking and sensation seeking (DRS-traits). Delay discounting and sensation seeking were inferred using self-reported behavioral data and health measurements for 80,676 participants in the UK Biobank. Multiple linear regression analysis produced beta coefficients and confidence intervals for each DRS-trait and job satisfaction. Analyses were adjusted for age, socioeconomic status and sleep quality. A combination of the three DRS-traits (CDRS) was assessed as well. Delay discounting and risk-taking were associated with, respectively, lower and higher job satisfaction in both sexes. Sensation seeking had no significant association with job satisfaction for either sex. The combined score, CDRS, was only negatively associated with job satisfaction in females but not in males. We discuss that the negative association between delay discounting and job satisfaction may be due to career related delay discounting effects, but also highlight that low job satisfaction itself may also lead to increased delay discounting. Additionally, we discuss why increased risk-taking behavior may have a positive effect on job satisfaction.

Effect of worry, depression, and sensitivity to environmental stress owing to neurotic personality on risk of cardiovascular disease: A Mendelian randomization study.

OBJECTIVE: This study investigated the putative causal link between neuroticism (using three genetically distinct subclusters namely depressed affect, worry, and sensitivity to environmental stress and adversity [SESA]) and cardiovascular disease (CVD). METHOD: A two-sample bi-directional Mendelian randomization (MR) approach was used. Genetic instruments were extracted from publically available GWAS summary statistics. RESULTS: In forward MR analyses with neuroticism subclusters as exposures, no causal associations between worry or SESA cluster and any of the CVD traits were observed (p > .05 for all). However, a higher risk of having heart failure (odds ratio (95% confidence interval):1.32(1.12 to 1.56); p = .0011) and myocardial infarction (1.47[1.18 to 1.83]; p = 6.3 × 10-4) associated with depressed affect cluster was observed. In reverse MR analyses with CVD traits as exposures, no significant associations were observed (p > .05 for all). CONCLUSIONS: Individuals with high neuroticism who are more susceptible to depressive symptoms are at higher risk for developing heart failure and myocardial infarction and should be more carefully evaluated for CVD risk in clinical settings. These individuals can potentially benefit from interventions aimed at reducing depressive symptoms to decrease CVD risk. There is no evidence to suggest that being sensitive to environmental stressors or being more worried can increase the risk for CVD.
