ObjectivesTo present population-based resting heart rate (RHR) percentiles and associated factors in children and adolescents.Study designStandardized RHR measurements with an oscillometric device were obtained from 3- to 17-year-olds who participated in the German Health Interview and Examination Survey for Children and Adolescents (nâ=â11 986). Age- and sex-specific RHR percentiles were derived using flexible age-dependent modeling. Linear regression was used to test associations of RHR and associated factors.ResultsRHR decreased with age and mean RHR was on average 3.0âbeats per minute (bpm) higher in girls than in boys (Pâ<â.01). The 95th RHR-KiGGS-percentile (P95) in boys and girls are up to 10âbpm lower than P95 based on pooled heterogeneous international studies and more similar to percentiles based on population data from NHANES (higher or lower by â¤5 bpm, depending on age). Factors independently associated with RHR in both sexes were age, SBP and height in children aged 3-10 years; and age, systolic blood pressure, and high aerobic fitness in adolescents aged 11-17 years. In girls, we further found an association between RHR and underweight (OR 3.3 and 4.7 for underweight girls aged 3-10 and 11-17, respectively, compared with normal weight girls). Associations between RHR and aerobic fitness, physical activity, and media use were stronger in boys than in girls.ConclusionThis study provides population-based RHR percentiles and evidence for sex-dependent associations of cardiovascular risk factors with RHR in children and adolescents, many of which are lifestyle related.
