    Abstract
    Obesity and low level of cardiorespiratory fitness are associated with high blood pressure in both adolescents and adults. The objective of this study was to assess the relationship of adiposity and cardiorespiratory fitness with resting blood pressure in 14-year-old male and female adolescents. Cross-sectional data on 310 adolescents (31.8% boys) from six high schools, who were participating in the on-going Physical Activity and Health Longitudinal Study, were collected. Height, weight, body mass index (BMI), percentage of body fat, waist circumference, waist-to-height ratio, predicted Unfortunately we are unable to provide accessible alternative text for this.

The prevalence of elevated SBP and DBP were 4.9% and 6.5%, respectively. The highest prevalence of elevated blood pressure (SBP=10% and DBP=15%) were measured in overweight adolescents, who also performed poorly for predicted Unfortunately we are unable to provide accessible alternative text for this.

Multiple regression showed that BMI was positively associated with SBP (β=0.77, P=0.005) and Unfortunately we are unable to provide accessible alternative text for this.

Overweight adolescents presented with a relatively high prevalence of elevated blood pressure and poor health-related fitness. Fatness and poor cardiorespiratory fitness were positively associated with elevated SBP and DBP, respectively. In view of the health implications of these findings, strategic interventions are needed to promote obesity-reduction programmes and physical activities in adolescents
