Research indicates that elevated plasma adropin levels are associated with increased systolic blood pressure variability in older adults, particularly those on antihypertensive medications. This suggests that adropin may serve as a potential biomarker for poor blood pressure control in this population.
What the research shows
The study investigated the relationship between circulating adropin concentrations and blood pressure (BP) variability in older adults participating in the Multidomain Alzheimer Prevention Trial (MAPT). The cohort included 443 community-dwelling participants with an average age of 75.9 years, and BP measurements were taken every six months over five years. The research employed multivariate regression modeling to identify associations between adropin levels and variability in systolic BP, independent of mean BP levels.
Why it matters for longevity
Hypertension and its variability are significant risk factors for cardiovascular, kidney, and neurodegenerative diseases, particularly in older adults. As individuals age, maintaining stable blood pressure is crucial for overall health and longevity. The findings suggest that monitoring adropin levels could provide insights into blood pressure control, potentially guiding interventions to improve health outcomes in aging populations. The link between adropin and BP variability may also indicate a broader role for this hepatokine in cardiovascular health and metabolic regulation.
Key findings at a glance
- Higher circulating adropin levels are positively associated with systolic blood pressure variability.
- The study involved 443 older adults, with an average age of 75.9 years.
- The association between adropin and BP variability was particularly strong in participants on antihypertensive therapy.
- Adropin may serve as a biomarker for assessing risk of poor blood pressure control.
- Age, sex, and antihypertensive medication use were significant predictors of BP variability alongside adropin levels.
How Adropin works (background)
Adropin is a hepatokine, a type of signaling protein produced by the liver, that plays a role in metabolic and cardiovascular health. It is involved in regulating energy homeostasis and has been linked to endothelial function and vascular elasticity. Adropin's actions may help mediate cellular stress responses in various tissues, suggesting its potential importance in maintaining cardiovascular health and metabolic balance, particularly in older adults. Research indicates that understanding its role could lead to new strategies for managing hypertension and related cardiovascular risks.
Safety, caveats, and what we don't yet know
While the study identifies adropin as a potential biomarker for blood pressure variability, further research is needed to establish causality and the mechanisms by which adropin influences blood pressure control. The study's population was limited to older adults, so findings may not be generalizable to younger populations. Additionally, the effects of adropin in individuals without hypertension or those not on antihypertensive medications require further exploration. Future studies should also investigate the potential therapeutic implications of modulating adropin levels.
Bottom line
Research indicates that elevated plasma adropin levels are associated with increased systolic blood pressure variability in older adults, particularly those on antihypertensive medications. This suggests that adropin may serve as a potential biomarker for poor blood pressure control in this population.

Can Adropin improve endothelial function in aging individuals?
Research suggests that adropin is linked to endothelial function, which is crucial for vascular health. However, specific studies examining its direct effects on endothelial function in aging individuals are still needed.
Does Adropin influence metabolic health in older adults?
Adropin has been associated with metabolic regulation, but more research is required to determine its specific effects on metabolic health and its potential role in age-related metabolic disorders.
What role does Adropin play in cardiovascular disease prevention?
While adropin is linked to cardiovascular health, particularly in relation to blood pressure variability, further studies are necessary to clarify its role in cardiovascular disease prevention and management.
