Stress may have a bigger effect on the hurried journey from infancy to adulthood than we may think. Recent study is revealing a concerning association between childhood stress and the future risk of cardiovascular disease.
Young adults who report higher levels of stress from adolescence to adulthood are more likely to have high blood pressure, obesity, and other cardiometabolic risk factors, according to the Journal of the American Heart Association, 2024.

Childhood stress is a complicated web of experiences that can have a lasting impact on an individual’s cardiometabolic well-being and cloud their health journey. Numerous studies have shown the intricate pathways by which stress throughout childhood influences the development of cardiovascular disease risk factors.

How Childhood Stress Takes Its Toll?

  1. Hormonal chaos: The hypothalamic-pituitary-adrenal (HPA) axis balance, which governs the levels of stress hormones, is the main focus. Cortisol and adrenaline from stress can affect lipid metabolism, blood pressure, blood sugar, inflammation, and inflammation, which increases the risk of cardiovascular disease.
  2. Nervous system navigation: Prolonged stress causes disturbance to the autonomic nervous system, which regulates blood flow, heart rate, and blood vessel tone. Elevations in heart rate, blood pressure, and vascular resistance can happen due to an imbalance between the sympathetic and parasympathetic branches.
  3. Impact on the immune system: Stress triggers the immune system and causes the release of cytokines that promote inflammation. This can cause damage to the blood vessel endothelial cells, which can lead to atherosclerosis.

  1. Epigenetic edits: Changes are made to the epigenome, the finely crafted script that modifies gene expression without changing the DNA sequence. Stress alters genes linked to the control of the cardiometabolic system, which may increase the risk of long-term health issues.
  2. Lifestyle lens: An individual’s behaviours and lifestyle choices are puppeteered by stress experienced during childhood. Numerous factors, including food preferences, physical activity levels, alcohol and tobacco use, and sleep patterns, contribute to the overall risk of cardiometabolic disease.

What Does the Research Reveal?

Journal of the American Heart Association, 2020: The chance of cardiovascular disease in later life was 50% higher in children who experienced significant adversity.
Circulation, 2019: In adulthood, women who experienced childhood hardship were more likely to have dyslipidemia, insulin resistance, and inflammation.

Implications And Intervention: Breaking the Chain

Childhood Stress Affects Mental Health

Early stress reduction and coping skill development therapies appear to be protective factors against the onset of cardiovascular illnesses. Uncovering the complexities of early childhood stress and laying the groundwork for a resilient, healthy future are urgent priorities.
