Adverse childhood experiences and incident coronary heart disease: a counterfactual analysis in the Whitehall II prospective cohort study

Cross-sectional study on the impact of adverse childhood experiences on coronary flow reserve in male physicians with and without occupational burnout

OBJECTIVE

Physicians face documented challenges to their mental and physical well-being, particularly in the forms of occupational burnout and cardiovascular disease. This study examined the previously under-researched intersection of early life stressors, prolonged occupational stress, and cardiovascular health in physicians.

METHODS

Participants were 60 practicing male physicians, 30 with clinical burnout, defined by the Maslach Burnout Inventory, and 30 non-burnout controls. They completed the Adverse Childhood Experiences (ACE) Questionnaire asking about abuse, neglect and household dysfunctions before the age of 18, and the Perceived Stress Scale to rate thoughts and feelings about stress in the past month. Endothelium-independent (adenosine challenge) coronary flow reserve (CFR) and endothelium-dependent CFR (cold pressor test) were assessed by positron emission tomography-computed tomography. The segment stenosis score was determined by coronary computed tomography angiography.

RESULTS

Twenty-six (43%) participants reported at least one ACE and five (8%) reported ≥4 ACEs. A higher ACEs sum score was associated with lower endothelium-independent CFR (r partial (rp) = -0.347, p = .01) and endothelium-dependent CFR (rp = -0.278, p = .04), adjusting for age, body mass index, perceived stress and segment stenosis score. In exploratory analyses, participants with ≥4 ACEs had lower endothelium-independent CFR (rp = -0.419, p = .001) and endothelium-dependent CFR (rp = -0.278, p = .04), than those with <4 ACEs. Endothelium-dependent CFR was higher in physicians with burnout than in controls (rp = 0.277, p = .04). No significant interaction emerged between burnout and ACEs for CFR.

CONCLUSION

The findings suggest an independent association between ACEs and CFR in male physicians and emphasize the nuanced relationship between early life stressors, professional stress, and cardiovascular health.

Adverse childhood experiences and subsequent physical and mental health among young adults: Results from six universities in China

Research has shown that individuals with adverse childhood experiences (ACEs) are more likely to encounter heightened risks of physical and psychological challenges later in life. However, limited research has explored the comprehensive impact on the physical and mental health of young adults. Thus, we conducted a study to investigate the associations of ACEs with the physical and mental health of 18,723 college students in China. Their physical and mental health status was assessed using self-perceived health assessments, self-reported disease diagnoses, and the Generalized Anxiety Disorder-7-item scale. Results showed that 82.6 % of participants had experienced at least one ACE, with 10.7 % reporting exposure to four or more ACEs. Compared to participants with low ACEs exposure (≤ 1), participants with high ACEs exposure (≥ 4) had a nearly twofold increase in the odds of cardiometabolic diseases (OR [95 % CI] = 2.06 [1.55-2.74]) and fractures (2.32 [1.88-2.87]). Additionally, individuals with high ACE exposure exhibited a threefold increased odds of severe anxiety symptoms (3.78 [2.59-5.51]) and bipolar disorder/schizophrenia (3.38 [2.18-5.23]). These findings highlight ACEs as a significant risk factor for poor physical and mental health among young adults. Targeted support and interventions for individuals with multiple ACEs may help mitigate their long-term disease burden.

Psychological stress, body shape and cardiovascular events: Results from the Whitehall II study

Background and aim

It is known that persistent psychological stress predicts changes in body shape in two different ways: some stressed people lose weight, others gain weight. It is also known that persistent psychological stress predicts adverse health events. But it is unknown what role the body shape plays in this particular network of relationships. We therefore analyzed the Whitehall II dataset to relate body shape to stress and health risk.

Methods

Data of 4969 men and 2138 women from the Whitehall II cohort were analyzed. Psychological stress (General Health Questionnaire) was measured three times in the years 1991 till 2001. Body shape (BMI, waist and hip circumferences) was measured in the years 1991 till 1994. Childhood adversities were retrospectively assessed by questionnaire. Outcomes included the incidence of non-fatal or fatal CHD events (coronary heart disease) collected up to the years 2012 and 2013 and all-cause mortality collected up to July 2015. Cox proportional hazard models were conducted to estimate the relation between psychological stress and CHD events or all-cause mortality.

Results

There was an increase in the expected hazard to develop CHD with high psychological stress (men: Exp (B) = 1.25 (1.06–1.47); P = 0.008; women: Exp (B) = 1.34 (1.05–1.70); P = 0.017). We found a clear dose-response relationship for the association between psychological stress and CHD events in both genders. That is, subjects with consistently high psychological stress in all assessments had a 2.4-fold (men) or 2.3-fold (women) higher risk for later CHD events compared to never-stressed subjects. Moreover, subjects with a high sum score of all 13 childhood experiences had a 10% increased hazard to develop fatal or non-fatal CHD events in adulthood. Although we could not find stress or BMI linked to all-cause mortality, the waist-to-hip ratio contributed to the risk of all-cause mortality in both genders (Exp (B) = 34.66 (6.43–186.92); P < 0.001 for men; Exp (B) = 60.65 (9.33–394.22); P < 0.001 for women).

Conclusion

This analysis supports the notion that psychological stress and childhood adversities are associated with the risk of fatal or non-fatal CHD events. When this relationship is analyzed in more detail, the Whitehall II dataset provides further insights into the role of body shape. That is, stress is also related to changes in body shape, with waist size in particular predicting higher all-cause mortality.

•

We used Whitehall II data and constructed an overall picture of the relations between psychological stress, body shape and adverse health outcomes.

•

We demonstrated a dose-dependent relationship between psychological stress and the risk of fatal or non-fatal CHD events.

•

Stress increases the risk of both CHD events and body shape changes, with waist circumference but not BMI increasing the mortality risk.

•

Body shape –more specifically waist size– is symptomatic of stress and predictive of all-cause mortality.
