What's your ACE score, and what does that mean for your health?

What happened to thousands of teens from the 1990s?

Scientists followed thousands of teenagers from 1997 into their 30s, cataloging their adverse experiences along the way via nearly three decades of interviews. Teens who grew up dealing with poverty, uninvolved parents, and other childhood stressors and traumas racked up an ACE score. These adverse childhood experiences have lifelong impacts on one's health, relationships, financial security, and "pretty much everything else," making them more likely to suffer premature death.

How trauma gets ‘under the skin’

A study examining the muscle function of older adults who have at least one adverse childhood experience (ACE) suggests that trauma digs itself into muscle cells. Participants who reported childhood trauma were found to have lower maximum levels of cellular energy than people who reported fewer or no ACEs. Such compromised mitochondrial function "doesn't bode well," as it relates to a variety of health and age-related outcomes.

Polygenic scores aim to predict traits based on the contributions of many genes

These novel tests for multifactorial conditions evaluate the probability of traits like elevated blood pressure, diabetes, or high cholesterol based on what researchers currently know about different gene variants and their links to various traits. The tests are predictive, not definitive, partly because environmental factors influence the expression of genes. What's more, knowledge about cumulative effects from individual genes continues to evolve. The American Society for Reproductive Medicine states that these tests are too unreliable and nascent for clinical use.

Blood Pressure and Diabetes

New meta-analysis shows blood pressure reductions with ACE inhibitors and ARBs are associated with a lower diabetes risk, but other types of antihypertensive agents have the opposite effect.
