Introduction: Recently, we established that a group of obese children and adolescents had a higher blood pressure(BP) than a healthy control group. In the present study, weinvestigate whether the higher BP in the obese group wasinfluenced by BP cuff sizes.Methods: A total of 104 obese patients aged 10-18 yearswere compared with 50 controls. BP was measured with avalidated oscillometric device using an appropriate cuff sizedepending on each person’s arm circumferences (AC) accordingto the manufacturer’s recommendation; small(AC < 23 cm), medium (23 ≤ AC < 32 cm) and large (AC ≥32 cm).Results: Cuff sizes had a significant impact on BP measurements.Despite the influence of cuff size, multiple regressionanalyses revealed that systolic BP was 68 mmHg higherand diastolic BP 32 mmHg higher in the obese groupthan in the control group. A step function, i.e. a sudden fallin BP, was seen at the point of switching from small to mediumcuff size in the control group, which suggests that systolicBP was overestimated when using small cuff size andunderestimated when using medium cuff size in subjectswith an AC near 23 cm.Conclusions: BP was higher in the obese group than inthe control group although BP was influenced by BP cuffsizes.Funding: The present project received funding from TheHealth Sciences Research Foundation of Region Zealand,The Danish Heart Foundation, Kathrine og Vigo SkovgaardsFond, Det Medicinske Selskab i København, Edith og HenrikHenriksens Mindelegat and LEO Pharma’s Travel Grant.
