Emotional stability, conscientiousness, and self-reported hypertension in adulthood

Perseverative Cognition as a Mediator Between Personality Traits and Blood Pressure

Purpose

Several authors link hypertension with psychological dispositions such as stress, personality, and anxiety, some propose that stress is not enough to explain arterial hypertension and others propose the perseverative cognition model to explain. The aim of this study was to relate personality traits and blood pressure profile of a group of workers, examining the results of perseverative cognition as a possible mediating variable concerning blood pressure.

Patients and Methods

Cross-sectional design study, with a sample of 76 employees of a Colombian university. The NEO-FFI, RRS, and blood pressure measurement instruments were applied; data were reviewed through correlation and mediation analysis.

Results

We found evidence of association between neuroticism and perseverative cognition (rho=0.42 with brooding; rho =0.32 with reflection), but no evidence about mediation of perseverative cognition between personality and blood pressure.

Conclusion

It is necessary to keep researching the mechanisms related to the occurrence of hypertension.

The Relationship between Conscientiousness and Well-Being among Chinese Undergraduate Students: A Cross-Lagged Study

Chinese culture attaches great importance to the education and cultivation of youth conscientiousness, however in the context of Chinese culture, little is known about the relationship between conscientiousness and mental and physical health. The present study aimed to investigate whether there is a reciprocal relationship between conscientiousness and well-being (subjective and physical well-being) among Chinese undergraduate students. A series of self-reported questionnaires were administered to 365 undergraduate students in 2 waves, separated by 1 year. Cross-lagged regression analyses were applied to examine the reciprocal relationships. Results indicated that conscientiousness positively predicted subsequent levels of positive affect and life satisfaction, while negatively predicted subsequent levels of negative affect and physical symptoms, controlling for the effects of gender, age, body-mass index, socioeconomic status, and the prior level of conscientiousness. Whereas, positive and negative affect, life satisfaction, and physical symptoms did not significantly predict subsequent levels of conscientiousness. This study suggests that conscientiousness is a robust and prospective predictor of subjective and physical well-being. The reciprocal relationship between conscientiousness and well-being was not confirmed in the current sample of Chinese undergraduate students.

Conscientiousness and Cardiometabolic Risk: A Test of the Health Behavior Model of Personality Using Structural Equation Modeling

BACKGROUND

High trait conscientiousness is associated with lower cardiometabolic risk, and health behaviors are a putative but relatively untested pathway that may explain this association.

PURPOSE

To explore the role of key health behaviors (diet, physical activity, substance use, and sleep) as links between conscientiousness and cardiometabolic risk.

METHODS

In a cross-sectional analysis of 494 healthy, middle-aged working adults (mean age = 42.7 years, 52.6% women, 81.0% White), participants provided self-reports of conscientiousness, physical activity, substance use, diet, and sleep, and wore monitors over a 7-day monitoring period to assess sleep (Actiwatch-16) and physical activity (SenseWear Pro3). Cardiometabolic risk was expressed as a second-order latent variable from a confirmatory factor analysis involving insulin resistance, dyslipidemia, obesity, and blood pressure. Direct, indirect, and specific indirect effect pathways linking conscientiousness to health behaviors and cardiometabolic risk were examined. Unstandardized indirect effects for each health behavior class were computed separately using bootstrapped samples.

RESULTS

After controlling for demographics (sex, age, race, and education), conscientiousness showed the predicted, inverse association with cardiometabolic risk. Among the examined health behaviors, objectively-assessed sleep midpoint variability (b = -0.003, p = .04), subjective sleep quality (b = -0.003, p = .025), and objectively-assessed physical activity (b = -0.11, p = .04) linked conscientiousness to cardiometabolic risk.

CONCLUSIONS

Physical activity and sleep partially accounted for the relationship between conscientiousness and cardiometabolic risk.

Conscientiousness and perceived physical symptoms: Mediating effect of life events stress and moderating role of resting respiratory sinus arrhythmia

This study investigated the possible psychophysiological links between conscientiousness and perceived physical symptoms by examining the mediating role of life events stress and the moderating role of resting respiratory sinus arrhythmia (RSA). Participants participated in the collection of questionnaire data and physiological data (N = 396). Results showed life events stress mediated the association between conscientiousness and perceived physical symptoms, and the indirect effect was only significant among individuals with lower resting RSA. Findings indicate that low resting RSA as a risk-amplifying physiological marker may magnify the relationship that low conscientiousness affects physical symptoms by increasing life events stress.

Five Factor Model Personality Traits and Subjective Cognitive Failures

Momentary lapses in memory, perception, or action, known as cognitive failures, are relatively common. These lapses may reflect, in part, aspects of psychological functioning, such as personality traits. The present research addresses how Five Factor Model personality traits and facets are associated with cognitive failures, and whether these associations are accounted for by depressed affect. Participants (N=5,133; 50% female) who ranged in age from 18 to 91 completed an online survey that assessed their personality traits, cognitive failures, and depressed affect. Higher neuroticism was associated with more cognitive failures, whereas Conscientiousness and Agreeableness were associated with fewer failures, controlling for sociodemographic characteristics. Controlling for depressed affect reduced the associations in most cases by about 50%, but most relations were still apparent. Facet-level analyses provided a more detailed picture of how the traits are associated with cognitive failures. Subjective perceptions of lapses in cognition are associated with basic personality traits and may reflect, in part, processes related to those traits beyond depressed affect.

Impact of major depression on cardiovascular outcomes for individuals with hypertension: prospective survival analysis in UK Biobank

OBJECTIVES

To assess whether a history of major depressive disorder (MDD) in middle-aged individuals with hypertension influences first-onset cardiovascular disease outcomes.

DESIGN

Prospective cohort survival analysis using Cox proportional hazards regression with a median follow-up of 63 months (702 902 person-years). Four mutually exclusive groups were compared: hypertension only (n=56 035), MDD only (n=15 098), comorbid hypertension plus MDD (n=12 929) and an unaffected (no hypertension, no MDD) comparison group (n=50 798).

SETTING

UK Biobank.

PARTICIPANTS

UK Biobank participants without cardiovascular disease aged 39-70 who completed psychiatric questions relating International Classification of Diseases-10 Revision (ICD-10) diagnostic criteria on a touchscreen questionnaire at baseline interview in 2006-2010 (n=134 860).

PRIMARY AND SECONDARY OUTCOME MEASURES

First-onset adverse cardiovascular outcomes leading to hospital admission or death (ICD-10 codes I20-I259, I60-69 and G45-G46), adjusted in a stepwise manner for sociodemographic, health and lifestyle features. Secondary analyses were performed looking specifically at stroke outcomes (ICD-10 codes I60-69 and G45-G46) and in gender-separated models.

RESULTS

Relative to controls, adjusted HRs for adverse cardiovascular outcomes were increased for the hypertension only group (HR 1.36, 95% CI 1.22 to 1.52) and were higher still for the comorbid hypertension plus MDD group (HR 1.66, 95% CI 1.45 to 1.9). HRs for the comorbid hypertension plus MDD group were significantly raised compared with hypertension alone (HR 1.22, 95% CI 1.1 to 1.35). Interaction measured using relative excess risk due to interaction (RERI) and likelihood ratios (LRs) were identified at baseline (RERI 0.563, 95% CI 0.189 to 0.938; LR p=0.0116) but not maintained during the follow-up.

LIMITATIONS

Possible selection bias in UK Biobank and inability to assess for levels of medication adherence.

CONCLUSIONS

Comorbid hypertension and MDD conferred greater hazard than hypertension alone for adverse cardiovascular outcomes, although evidence of interaction between hypertension and MDD was inconsistent over time. Future cardiovascular risk prediction tools may benefit from the inclusion of questions about prior history of depressive disorders.

Associations between childhood biomedical factors, maternal smoking, personality traits, Body and Mass Index and the prevalence of asthma in adulthood

OBJECTIVE

The study set out to investigate socio-economic, biomedical, health and behavioural and psychological factors in childhood and adulthood associated with the prevalence of asthma in adulthood, drawing data from The National Child Development Studies (NCDS), a birth cohort in the UK.

DESIGN

The National Child Development Study, a nationally representative sample of 17,415 babies born in Great Britain in 1958 and followed up at 7, 11, 33 and 50 years was used.

MAIN OUTCOME MEASURE

The prevalence of asthma at age 50 was the outcome measure. The analytic sample consists of 5118 participants with complete data on a set of measures at birth, at ages 7, 11, 33 and 50 years.

RESULTS

Using logistic regression analyses, results showed that childhood asthma (OR = 6.77: 4.38-10.48, p < .001) and respiratory symptoms (OR = 1.83: 1.18-2.86, p < .01), maternal smoking during pregnancy (OR = 1.26: 1.00-1.59, p < .05), Body and Mass Index (BMI) (OR = 1.03: 1.02-1.05, p < .001), traits Neuroticism (OR = 1.13: 1.01-1.21, p < .05) and Conscientiousness (OR = 0.76: 0.76-0.96, p < .01), as well as sex (OR = 1.49: 1.15-1.94, p < .001) were all significantly associated with the prevalence of asthma in adulthood.

CONCLUSION

The study shows that both childhood and adulthood psychological and sociological factors are significantly associated with the prevalence of asthma in adulthood, though more work need to be done in this area.

Personality and metabolic dysfunction in young adulthood: A cross-sectional study

This research used the National Longitudinal Study of Adolescent to Adult Health ( N = 15,359; age range 25–34) to examine the cross-sectional relation between personality and four components of metabolic syndrome (elevated glucose, blood pressure, cholesterol, and waist circumference) and a metabolic risk index in young adulthood. Consistent with research on older adults, higher Neuroticism and lower Conscientiousness were associated with greater risk of metabolic dysfunction; Agreeableness, however, was unrelated to it. The relation between personality and metabolic health may unfold across the lifespan, with the association between Neuroticism/Conscientiousness and metabolic dysfunction starting early and the association with Agreeableness emerging at older ages.
