Emerging cardiovascular risk factors in childhood and adolescence: a narrative review

Abstract

It is widely recognized that four key health behaviors—regular physical activity, maintaining a normal BMI, eating a healthy diet, and avoiding smoking—offer significant protection against cardiovascular disease in children and adolescents. However, changes in the lifestyle of families have contributed to the emergence of new behaviors that may impact the health of children and adolescents. This narrative review aims to identify existing evidence on the effect of these arising habits on the cardiovascular health of children and adolescents, mainly on blood pressure and endothelial function. A thorough search was conducted across various databases, including PubMed/MEDLINE, the Cochrane Library, Science Direct and EBSCO. Conclusion: Some of the behaviors most frequently identified in the pediatrician’s office are childhood stress and behavioral disorders, new forms of nicotine consumption, the impact of the use of screens and digital devices, changes in sleep patterns, and, finally, the generalization of energy drinks and supplements to promote muscle development, mainly in adolescents. The effect on cardiovascular health, mainly on blood pressure, does not seem negligible. Early identification of these unhealthy behaviors might allow the pediatrician to intervene and prevent the progression of cardiovascular disease. (Table presented.)
