No full textBackground
Little is known about arterial stiffness in rural subsistence populations that experience few cardiovascular risk factors. We conducted a cross‐sectional study comparing 3 arterial stiffness metrics among Tsimane forager‐horticulturalists with 2 representative US cohorts.
Methods
Arterial elasticity (the inverse of stiffness) markers C1 (large artery elasticity) and C2 (small artery elasticity) were measured using a tonometry device among 490 Tsimane adults (mean age, 51.2±10.1 years; 55% women), and compared with 6294 multiethnic US adults (mean age, 62.0±10.2 years; 52% women) from MESA (Multi‐Ethnic Study of Atherosclerosis). Carotid‐femoral pulse wave velocity was assessed using the foot‐to‐foot method in a smaller Tsimane sample (n=94) and compared with 3086 predominantly White US adults (mean age, 46.1±8.7 years; 54% women) from the FHS Gen3 (Framingham Heart Study Third Generation).
Results
Tsimane participants exhibited superior arterial health compared with US cohorts, with higher elasticity (C1/C2) and lower stiffness (carotid‐femoral pulse wave velocity). Their C1 (mean 22.8±12.2 mL/mm Hg×10) and C2 (mean 7.5±4.0 mL/mm Hg×100) were 47.3% and 35.7% higher than MESA participants by age 40 years, respectively, and differences remained sustained throughout adulthood. Compared with participants in FHS Gen3, the carotid‐femoral pulse wave velocity in Tsimane participants (mean 6.2±1.2 m/s) was 33.9% lower and showed a minimal age‐related increase, with carotid‐femoral pulse wave velocity only higher by age 70+ (β=1.74±0.38; reference <40 years). Tsimane participants with ≥2 comorbidities (hypertension, obesity, and diabetes) had ≈25% higher arterial elasticity than healthy Americans with no comorbidities.
Conclusions
Tsimane forager‐farmers of the Bolivian Amazon demonstrate substantially lower arterial stiffness throughout adulthood than more urbanized and sedentary populations, and the differences are only partially explained by conventional cardiometabolic risk factors

No full textThe role of change in the relationships among decent work, political cynicism and voter turnout
No full textThreats to decent working conditions and cynical views of politicians are increasingly prevalent in contemporary societies. The present study examines the potential relationship between these two trends and the mediating role that anger-related emotions may play in this relationship. Using latent growth modeling analyses and data from a panel survey of French employees collected during the 2021–2022 French electoral cycle, I found that within-person decreases in employees' perceptions of decent work were associated with within-person increases in anger and hostility toward the employing organization; increases in anger and hostility, in turn, were associated with within-person increases in political cynicism. Moreover, both initial levels and increases in political cynicism were associated with a lower likelihood of electoral participation. Overall, this research highlights how longitudinal change in workplace experiences may drive the dynamics of political cynicism and indirectly affect the vitality of democracy
The Ethical Downside of Giving Employees the Trust They Want: When Trust Congruence Leads to Unethical Pro-supervisor Behavior
No full textRecent research and conventional wisdom suggest that behavioral demonstrations of trust by supervisors toward their subordinates are most effective when those demonstrations match subordinates’ desires. In the present research, we offer a more nuanced view by identifying one downside of a match between supervisors’ expressions and subordinates’ desired trusting behaviors (i.e., trust congruence). Namely, this situation may inadvertently encourage subordinates to engage in unethical acts with the intention of benefiting their supervisor (i.e., unethical pro-supervisor behavior; UPSB). Drawing on social exchange theory and moral disengagement theory, we argue that trust congruence helps promote positive social exchange relationships between supervisors and subordinates. The desire to maintain or reinforce these relationships, in turn, leads subordinates to engage in UPSB indirectly via moral disengagement. We further argue that ethical leadership represents an important boundary condition regarding this process, as it guides subordinates’ social exchange responses and thus prevents them from engaging in behaviors that are not aligned with the ethical expectations of their supervisors. Our model is progressively supported by four main studies (an experiment and three time-lagged field studies) and two supplemental studies. This research improves our understanding of the ethical consequences of trust congruence and has practical implications for organizations seeking to support trust-building initiatives.

Ectopic Adipose Tissue in Subsistence Populations with Minimal Coronary Disease, Large Left Atria, and Very Low Rates of Atrial Fibrillation
No full textBackground
Greater deposits of epicardial adipose tissue are associated with atrial fibrillation and coronary disease, but have not been studied in subsistence populations.
Methods
We performed CT imaging to measure coronary artery and thoracic aortic calcium (CAC, TAC), epicardial fat thickness (EFT), liver density, and left atrial (LA) anteroposterior diameter and, using a deep learning-enabled software program, epicardial and thoracic fat volume (EFV, TFV), in two remote Amerindian subsistence populations with minimal coronary artery calcification and virtually no atrial fibrillation. We compared 893 adult Tsimane (mean age 58.3±10.5 y, 51.6% male), 440 Moseten (55.9±10.4 y, 53.6% male) to 955 U.S. (56.8±10.8 y, 51.6% male) subjects.
Results
Tsimane and Moseten had 43%-52% lower EFT, EFV, TFV, and 48-92% less CAC and TAC, respectively than the U.S. cohort. Mean liver measurements were 14-22% denser and LA diameters 10-14% larger (≈ 40% larger by volume). For EFV, Tsimane, Moseten, and U.S. cohorts averaged 54.2±25.6, 60.3±35.1, and 106±53.5 cc, respectively (p< 0.05 for all comparisons). EFV remained significantly smaller after adjustment for age, BMI, and other characteristics. For all CT metrics, the more acculturated Moseten measures were intermediate between Tsimane and the U.S. cohort.
Conclusions
Tsimane mean EFV was the lowest of any population ever reported in the literature, achieving a new population standard. The low levels of EFV in the Tsimane and Moseten add to the body of evidence linking ectopic fat and atherosclerosis and further confirm (in the negative) the association, and likely causative role, of epicardial fat and atrial fibrillation
