Cardiovascular risk factors in children and adolescents with anxiety disorders and their association with disease severity

Introduction: Studies suggest that anxiety is an independent predictor of adverse cardiovascular events. However, few studies have investigated the association between cardiovascular risk factors (RF) and severity of anxiety disorders (AD) in childhood and adolescents. Objectives: To assess the prevalence of cardiovascular RF in children and adolescents with anxiety disorders and their association with disease severity. Method: Cross-sectional study assessing nutritional and anthropometric RF, as well as % body fat (BF), blood pressure (BP), physical activity level, anxiety symptoms and severity of the anxiety disorder of children and adolescents. Results: A total of 65 children and adolescents (8.6 ± 1.7 years) took part in the study. Excess saturated fatty acid intake (52.3%), high body mass index (50.8%), high BP (50.8%) and physical inactivity (50.0%) were the most prevalent cardiovascular RF. There was a significant association between the severity of the anxiety and the presence of ≥ 6 RF per patient (p=0.026), excess abdominal body fat as assessed by waist circumference (p=0.019) and conicity index (p=0,053), and excess % BF (p=0.035). Generalized anxiety disorder was significantly associated with high BP (p=0.044). Conclusion: A high prevalence of cardiovascular RF was found in the present sample, and individuals with more severe anxiety had greater cardiovascular risk. The characterization of the cardiovascular risk in young populations, especially in individuals with AD who are therefore more susceptible to CVD, is crucial for the development of lifestyle interventions in these patients.
