The Pathways from Type A Personality to Physical and Mental Health Amid COVID-19: A Multiple-Group Path Model of Frontline Anti-Epidemic Medical Staff and Ordinary People

Type A personality, sleep quality, and cerebral small vessel disease: investigating the mediating role of sleep in a community-based study

Purpose

Type A behavior pattern (TABP) is a personality type characterized by rapid speech, impatience, competition, and hostility. Asymptomatic cerebral small vessel disease (CSVD) is often endemic in older adults. Individuals with TABP commonly experience suboptimal sleep quality, and a correlation exists between sleep disturbances and CSVD. We investigated the relationship between TABP and CSVD markers and further explored the mediating role of sleep quality in the relationship between TABP and CSVD.

Methods

A cross-sectional survey included 764 community-dwelling adults aged 55-85 years. The TABP Scale and the Pittsburgh Sleep Quality Index (PSQI) were used to assess personality and sleep quality, respectively. Linear and logistic regression analyses were used to examine relationships between variables of interest. In addition, mediation analyses with bootstrapping were used to test whether sleep quality mediated the relationship between TABP and CSVD.

Results

Of the 764 participants [median age 65 (61-69) years, 59.9% female], the population with type A personality accounted for 44.8%. After adjusting for covariates, TABP scores (p = 0.03) and PSQI scores (p < 0.001) were significantly correlated with CSVD. In addition, sleep quality partially mediated the association between type A behavior and CSVD, and the mediating effect was 10.67%.

Conclusion

This study showed that type A behavior was a risk factor for CSVD among older community-dwelling adults and that sleep quality mediated the relationship between type A behavior and CSVD. Changing type A behavior may help improve sleep quality, which may in turn reduce the prevalence of CSVD.

Neural correlates of Type A personality: Type A personality mediates the association of resting-state brain activity and connectivity with eating disorder symptoms

BACKGROUND

Type A personality (TAP) was characterized by impatience, competitiveness, aggressiveness, and hostility. Higher TAP was proved to be associated with more eating disorder symptoms (EDS). While little is known about the underlying neural substrates of TAP and how TAP is linked to EDS at the neural level.

METHODS

To investigate the neural basis of TAP, we adopted fractional amplitude of low-frequency fluctuations (fALFF) and resting-state functional connectivity (RSFC) via resting-state functional magnetic resonance imaging (rs-fMRI) (N = 1620). Mediation models were examined to explore the relationship between TAP, EDS, and brain activity.

RESULTS

TAP was associated with decreased fALFF in the left middle frontal gyrus (MFG) and increased fALFF in the left precentral gyrus (PreCG). Furthermore, TAP was positively correlated to RSFC between the left MFG and left inferior temporal gyrus (ITG) and between the left PreCG and right middle temporal gyrus (MTG). Mediation analysis showed TAP fully mediated the association of the left MFG activity, MFG-ITG connectivity, and PreCG-MTG connectivity with EDS.

LIMITATIONS

The cross-sectional design of this study precludes us from specifying the causal relationship in the associations we observed.

CONCLUSIONS

Our results suggested spontaneous activity in the left MFG and PreCG is associated with TAP, and even in general sample, people with higher TAP showed more EDS. The present study is the first to investigate the neurobiological underpinnings of TAP in a large sample and further offered new insights into the relation between TAP and EDS from a neural basis perspective.

Type A Behaviour Pattern and Health Behaviour of Polish Nurses

“Coronary prone behaviour pattern” refers to a way of coping with environmental stressors, otherwise known as type A behaviour patterns. Stress, unlimited working hours, and the shift system are conducive to an “unhealthy life style”, conducted by nurses. The aim of the study was to assess the “coronary prone behaviour pattern”, taking into account health behaviour and work performed by Polish nurses. Method: This was a descriptive study conducted from June 2017 to May 2018 among nurses (N = 1080) working primary care or in training facilities in Silesia, Poland. Data were acquired through a series of questionnaires and are presented as descriptive statistics. Results: The “coronary prone behaviour pattern” (type A behaviour) was manifested by 333 (30.8%) nurses, type B by 272 (25.2%). The “coronary prone behaviour pattern” respondents showed a risk of developing a problem with alcohol (p = 0.003) less frequently compared with other respondents. In addition, nurses with the abovementioned behaviour pattern ate better (M = 16.66; SD = 6.11) compared with those with the type B behaviour pattern (M = 15.49; SD = 6.52). In terms of mental and physical wellbeing, people with type A behavioural patterns had significantly (p < 0.001) better mental and physical wellbeing and, on average, better results in coping with stress compared with other behavioural patterns of nurses. Conclusion: The occurrence of the “coronary prone behaviour pattern” was associated with the health-promoting behaviours of nurses being the subject of the analysis, i.e., better mental and physical wellbeing, better ability to cope with stress, and a lower risk of problems with alcohol and proper nutrition.
