A new study reveals that certain personality traits may significantly impact the risk of cardiovascular disease (CVD) in individuals with type 2 diabetes mellitus (T2DM). The research, published online on September 10 in BMJ Open Diabetes Research & Care, underscores the role of personal characteristics in predicting cardiovascular health.
Led by Chan Soon Park from Seoul National University Hospital in South Korea, the study utilized data from 8,794 T2DM patients enrolled in the U.K. Biobank. The dataset spanned from 2006 to 2010 with follow-up extending to 2021. The researchers explored how traits such as sociability, warmth, diligence, curiosity, and nervousness correlate with cardiovascular outcomes and lifestyle factors.
Key findings from the study indicate that diligence, in particular, is associated with a lower risk of developing cardiovascular diseases. Over a median follow-up period of 13.6 years, higher diligence was linked to a reduced incidence of myocardial infarction, ischemic stroke, atrial fibrillation, and heart failure. The data showed a trend towards a lower composite outcome for CVDs with an adjusted hazard ratio of 0.93. Additionally, individuals with high or low levels of diligence benefited from healthy lifestyle practices, which further decreased their risk for cardiovascular issues.
The study’s structural equation modeling suggests that diligence affects cardiovascular risk both directly and indirectly by influencing lifestyle choices.
The researchers emphasize that these findings highlight the importance of integrating personality assessments into cardiovascular risk evaluations and adjusting lifestyle interventions for T2DM patients as a preventive measure.
