Greater environmental unsafety (B = 0.02) and daily social vigilance (B = 0.09) were significantly associated with greater 2-year progression of carotid intima media thickness in adults.
Observational (n=300)
This study found that social vigilance did not mediate the association between safety indicators and preclinical cardiovascular disease progression.
Mean Difference: 0.02 (95% CI 0.005–0.032)

OBJECTIVE: Despite robust evidence linking psychological stress to cardiovascular disease (CVD), explanations for how risk is transmitted are limited by a lack of ecologically valid models. Recent conceptual advances including generalized unsafety theory of stress and social safety theory articulate persistent physiological activation driven by contextual exposure and compensatory situational vigilance as a pathway. This study provides an integrated first test of generalized unsafety theory of stress and social safety theory models on preclinical CVD. METHOD: = 42.44 years; 50% women; 60% non-Hispanic (NH) Whites, 19% Hispanic/Latinos, 15% NH Blacks, 6% NH Others) completed a 2-year longitudinal study with surveys, ecological momentary assessment (EMA), and carotid artery scans measuring disease progression. Residential data were geo-coded to assess risk for crime exposure. Data collection occurred in 2012 and 2014. RESULTS: < .001) was associated with lower social vigilance, social vigilance did not mediate associations between either safety indicator and disease progression. CONCLUSIONS: Results align with a persistent activation conceptualization of stress and modestly support the specific theoretical assertions. These findings suggest future stress-CVD investigations should account for multilevel safety influences and continuous monitoring behavior to more accurately capture daily stress experiences.

O’Neill et al. (Mon,) conducted a observational in Preclinical cardiovascular disease (n=300). Environmental unsafety and social vigilance vs. Lower environmental unsafety and social vigilance was evaluated on 2-year change in carotid intima media thickness (cIMT) (B = 0.02, 95% CI 0.005-0.032, p=<0.05). Greater environmental unsafety (B = 0.02) and daily social vigilance (B = 0.09) were significantly associated with greater 2-year progression of carotid intima media thickness in adults.
