Problems of being identified as type D persons

Read this abstract about how even healthy people with negative affect and strong social inhibition can be at risk of cardiovascular disease. The article is worth a closer look, but if this is indeed as it is (note that this is only on the basis of a cross sectional survey so there is no notion of any causal factor yet). If this is true, then people with specific behavioral traits are not only more likely to die from cardiovascular disease, they are more likely to get them. It’s time to link cultural issues and world views with diseases.

Background: People with Type D -Distressed- personality have a general tendency towards increased negative affectivity (NA), while at the same time inhibiting these emotions in social situations (SI). Type D personality is associated with an increased risk of adverse outcomes in patients with cardiovascular disease. Whether Type D personality is a cardiovascular risk factor in healthy populations remains to be investigated. In the present study, the relations between Type D personality and classical cardiovascular risk factors, i.e. metabolic syndrome and lifestyle were investigated in a Dutch community sample. Methods: In a cross-sectional study 1592 participants were included, aged 20-80 years. Metabolic syndrome was defined by self-report, following the International Diabetes Federation -IDF- guidelines including an increased waist circumference, dyslipidemia, hypertension, and diabetes. In addition lifestyle factors smoking, alcohol use, exercise and dietary habits were examined. Metabolic syndrome prevalence was stratified by Type D personality (a high score on both NA and SI), lifestyle and confounders age, gender, having a partner, higher education level, cardiac history, family history of cardiovascular disease. Results: Metabolic syndrome was more prevalent in persons with a Type D personality (13% vs. 6%). Persons with Type D personality made poorer lifestyle choices, adhered less to the physical activity norm (OR=1.5, 95%CI=1.1-2.0, p=.02), had a less varied diet (OR=0.50, 95%CI=0.40-0.70, p<.0005), and were less likely to restrict their fat intake (OR=0.70, 95%CI=0.50-0.90, p=.01). Type D personality was related to a twofold increased risk of metabolic syndrome (OR=2.2, 95%CI=1.2-4.0, p=.011), independent of lifestyle factors and confounders. Conclusions: Type D personality is related to an increased prevalence of metabolic syndrome and unhealthy lifestyle, which suggests both behavioral and biological vulnerability for development of cardiovascular disorders and diabetes.
