Resting heart rate in children and adolescents: association with blood pressure, exercise and obesity

Abstract

Elevated RHR is independently associated with elevated BP in children, whereas increased structured exercise is related to lower RHR.

Association between resting heart rate and cardiovascular risk factors in adolescents

“…RHR is emerging as an easily measurable clinical parameter that is a predictive marker of cardiovascular disease (CVD) and mortality [19][20][21]42]. Elevated RHR is associated with higher levels of blood pressure, abdominal obesity, triglycerides, and glucose in children and adolescents [12,17,18,22,28], indicating its potential as a screening tool of cardiovascular risk in children.…”

“…Previous studies [12,17,18,22,28] have analyzed the association between cardiovascular risk factors and elevated RHR in adolescents, but several aspects remain less clear. For example, previous studies rarely considered the role of clustering of cardiovascular risk factors and its relationship with RHR in children and adolescents.…”

“…Risk factor clustering has also been associated with abnormal vascular structure and function in youth [36]. It has also been reported that both the RHR [26,28] and clustering of cardiovascular risk factors behave in a gender-dependent way [1]. It remains less clear if the association between the clustering of cardiovascular risk factors and RHR is also different between genders.…”

Comparação da frequência cardíaca em repouso medida usando um monitor cardíaco e um aparelho oscilométrico em adolescentes: análise de sensibilidade e especificidade

“…Recent studies with the objective of verifying resting heart rate in adolescents and associated factors have used oscillometric devices to measure the heart rate. 9,10 The expectation is that these devices may be used to assist in preventive measures related to risk factors for cardiovascular disease carried out in schools. There are currently no actions for effective promotion being carried out in such environments with regard to resting heart rate, however, recent studies indicate that this is a risk factor which must be evaluated from the earliest ages.…”

“…Epidemiological studies also indicate that elevated heart rate at rest is related to high blood pressure in children and adolescents. 10,11 Thus, evaluating resting heart rate at early ages seems to be an essential preventive action to prevent possible cardiovascular risk factors being initiated in childhood or adolescence. Oscillometric devices which measure systolic and diastolic blood pressure together with the resting heart rate may Zanuto EF, Saraiva BC, Vanderlei LCM, Costa Júnior P, Agostinete RR, Zanuto EAC, Fernandes RA, Christofaro DGD.…”
