“…Here, Type D personality was primarily associated with lower reactivity among females and in response to nonsocial stressors, and greater reactivity among males and in response to social stressors. Finally, one study reported an interaction effect of Type D and childhood trauma on cardiovascular reactivity (Bahari et al, 2021). While two studies reported no significant effects of Type D on cardiovascular reactivity for parameters analyzed in the current study (Allen et al, 2019a; Habra et al, 2003), four studies did not assess the association between the global Type D construct and cardiovascular reactivity (Brugnera et al, 2018, 2019; Howard & Hughes, 2013; Pattini et al, 2019).…”

“…However, it is also important to note all of these samples were either solely or predominantly composed of undergraduate students, of a relatively young age ( M = 21.36) and similar sample characteristics. Additionally, while Lü and Yao (2021) examined a Chinese sample, and Bahari et al (2021) examined an Iranian sample, all other studies included in the review examined western samples from Europe and North America. Sex differences in similar personality traits have been shown to vary cross-culturally (Costa et al, 2001; Schmitt et al, 2008).…”

Objectives: Type D personality has been associated with adverse cardiovascular health, with atypical cardiovascular reactions to psychological stress considered a possible mechanism of effect. However, studies examining Type D personality and cardiovascular reactions to acute stress have yielded mixed findings.Here, we conducted a systematic review and meta-analyses to examine if, and under what conditions, Type D personality is associated with cardiovascular reactivity to stress; a particular focus was placed on sex and the social salience of the stressor as potential moderators of effects. Method: Electronic databases (Medline, PsycArticles, PsycInfo, CINAHL, PubMed, Web of Science) were searched for relevant publications. A total of 401 articles were retrieved and screened for eligibility. Inclusion criteria included studies with nonclinical samples employing a resting baseline period followed by a psychological stress task period and measurement of cardiovascular reactivity. Following screening and removal of irrelevant articles, 17 peer-reviewed studies were included in the review. Result: Type D personality was associated with lower blood pressure reactivity to acute psychological stress. Subgroup analyses revealed an association between Type D personality and lower cardiovascular reactivity among females, but not males. Additionally, Type D personality was primarily associated with lower cardiovascular reactivity in response to nonsocial stressors. Conclusions: Type D personality is associated with lower blood pressure reactivity to acute psychological stress, particularly among females and in response to nonsocial stressors. This lower response may be indicative of blunted cardiovascular reactivity and therefore signals an increased risk of adverse health outcomes. Public Significance StatementThe current review indicates that Type D personality is associated with lower cardiovascular reactivity to acute stress, particularly among females and in response to nonsocial stressors. These lower cardiovascular responses may constitute a physiological mechanism leading to adverse cardiovascular health for Type D individuals.

“…Violence and trauma experienced during childhood may accelerate the aging process (Jovanovic et al, 2017 ; Rampersaud et al, 2022 ) and increase the risk for cardiovascular disease, premature mortality, depression, anxiety, and posttraumatic stress disorder (Bahari et al, 2021 ; Murali & Chen, 2005 ). Epigenetic clocks are estimators based on DNA methylation (DNAm) to measure biological age, reflecting the impact of lifetime exposures (Horvath, 2013 ).…”

Background: Cumulative exposure to violence can change the regulation of epigenetic and physiological markers. Although violence has been associated with accelerated cellular aging, little is known about associations with cardiac autonomic activity. Objective: The current study aimed to investigate the relationship of exposure to community and domestic violence (CDV) with vagal activity and epigenetic aging acceleration. Methods: A total of 86 adolescents (57% female) were evaluated and interviewed at two time-points in São Gonçalo (2014–2019), a Brazilian city with high levels of violence. Exposure to CDV was assessed in both time-points. GrimAge acceleration was calculated from saliva DNA methylation using Infinium HumanMethylation450K (Illumina) collected in the first assessment. Heart rate variability (HRV) was collected during two stress tasks at the second assessment. Results: The exposure to violence witnessed or directly experienced at home and in the community increased significantly ( t = 4.87, p < .01) across two-time points, and males had reported higher violence exposure ( t = 2.06, p = .043). Violence at 1st assessment was significantly associated with GrimAge acceleration ( B = .039, p value = .043). Violence at both assessments were associated with HRV measured during the narration of the worst trauma (traumaHRV) ( B = .009, p value = .039, and B = .007, p value = .024, 1st and 2nd assessment respectively). GrimAge acceleration was significantly associated with traumaHRV ( B = .043, p value = .049), and HRV measured during a 3D roller coaster video ( B = .061, p value = .024). Conclusions: We found relevant evidence that experiencing violence during adolescence is associated with epigenetic aging and stress-related vagal activity. Understanding these factors during this period could contribute to the development of early interventions for health promotion. HIGHLIGHTS Higher exposure to Community and domestic violence is associated with increased GrimAge acceleration. Higher GrimAge acceleration is associated with increased stress-related vagal activity. Exposure to community and domestic violence increased significantly over time.
