ABSTRACT
Objectives: Although there is substantial evidence that psychological factors play an important role in the onset
and course of cardiovascular disease (CVD), less is known about their combined effect and the pathways by
which they affect cardiovascular health. The present work aimed to prospectively explore the effects of de-
pression and anxiety on the 10-year CVD incidence, in relation to other lifestyle determinants, as linking factors
in the context of the ATTICA study. Study design/Main outcome measures: The ATTICA study is a population-
based, health and nutrition prospective cohort study (2002–2012), during which 853 middle-aged participants
without a history of CVD [453 men (aged 45 ± 13 years) and 400 women (aged 44 ± 18 years)], underwent
psychological evaluations at enrollment. The latent trait of depression and anxiety combined measure was es-
timated and referred as “Psychological distress”; path analysis was applied to describe the relationships among the
different factors.
Results: “Psychological distress” was positively associated with the 10-year CVD incidence (adjusted OR per 10
units: 1.4, 95% CI: 1.1, 1.7). Three linking pathways were revealed: sedentariness, inflammation and metabolic
syndrome. Moreover, “Psychological distress” mediated the association between socioeconomic status (SES) and
CVD, with participants of low SES scoring higher on the psychological measure (adjusted linear regression
coefficient b: -7.1, 95% CI: -9.7, -4.5).
Conclusions: Lifestyle and clinical factors seem to link psychological distress with CVD development. Joint
psychological assessments should be considered for inclusion in CVD preventive strategies, which should in-
corporate interventions for interrupting the linking pathways.
1. Introduction
Although there is evidence of declining rates of Cardiovascular
Disease (CVD) mortality in several European countries, according to the
recent European CVD Statistics (2017), CVD remains the leading cause
of death in Europe with an age-adjusted death rate up to 500 per
100,000 individuals (45% of all deaths; responsible for over 4 million
deaths per year) [1]. Moreover, mental disorders, such as depression
and anxiety, are now considered on the top-5 of main causes of
disability and morbidity in both genders in the developed world [2].
Several narrative and quantitative reviews of dozens of descriptive
epidemiological studies have concluded that psychological factors
predict CVD morbidity and mortality at primary and secondary level
(i.e., in individuals with or without previous cardiovascular history)
and relate to chronic diseases of adulthood [3]. In addition, depression
and anxiety have been both linked to two of the identified CVD risk
factors; socioeconomic inequalities [4] and the adaptation of unhealthy
lifestyle including unhealthy dietary habits [5]. Although, many
