Is Borderline Personality Disorder Linked to a Fast-Paced Life Strategy?
Open access · cc by · source: Europe PMC
Women with Borderline Personality Disorder show psychological and physical signs of a fast-paced life strategy, which is statistically explained by childhood trauma.
Key findings
The BPD group exhibited scores consistent with a fast pace-of-life syndrome, displaying higher levels of chronic stress, aggression, and childhood trauma compared to controls. They also showed a significantly higher allostatic load, pointing to worse physical body maintenance. Mediation analyses suggested that early childhood trauma predicted a faster pace-of-life strategy, which in turn predicted this higher physical wear-and-tear.
Methodology
Researchers compared 44 women diagnosed with Borderline Personality Disorder (BPD) against 51 healthy female controls of similar ages. Participants completed questionnaires assessing childhood trauma, life history strategies, personality traits, aggression levels, and chronic stress. Additionally, researchers measured the participants' blood pressure, waist-to-hip ratio, and body mass index to calculate an allostatic load score, representing physical wear-and-tear on the body.
Limitations
The study was cross-sectional, meaning it cannot definitively prove that childhood trauma or life history strategies cause physical health decline over time. The sample was entirely female and relatively young, so the findings may not apply to men or older populations whose physical wear-and-tear is more pronounced. The measurement of allostatic load relied only on four basic physical metrics like blood pressure and body mass index, omitting blood markers like insulin or cholesterol. Lastly, the researchers did not control for the participants' socioeconomic status, which can independently influence stress and health outcomes.
