Assessing Endothelial Function in Normotensive Overweight Adolescent Using Dundee Step Test.

Aim Normotensive overweight adolescents may have endothelial dysfunction which is not clinically detected in a routine clinical examination. The purpose of this study was to detect endothelial dysfunction in normotensive overweight using Dundee step test. Methods Sixty two subjects consist of 31 normoweight and 31 overweight group participated in this study. Blood pressure measurement was taken at rest and after 3 minutes Dundee step test. Hyper-responder was defined if systolic blood pressure reach 180 mmHg or more after 3 minutes exercise. Results Mann-Whitney test showed that overweight subjects had significantly higher resting systolic blood pressure, post exercise blood pressure anf magnitude of SBP change (Δ SBP) compared to control subjects (116.5 vs 112.8; 163.8 vs 142.7 vs; and 47.3 vs 29.9; P<0.05). Twenty six percent of overweight was diagnosed as hyper-responder. Conclusion There was significant association between overweight and ExSBP indicating endothelial dysfunction in normotensive overweight adolescents.

Comparison of the anthropometric measurements and health risks in people with normal weight according to the body mass index-for-age charts.

Aim Body mass index (BMI) at 5th-84th percentiles according to the BMI-for-age charts from Center for Diseases Control and Prevention (CDC) is considered as normal BMI for children and adolescents. However, Guo et al found that BMI at 75th-84th percentiles already had a possibility to be adult overweight and obese. This study aimed to determine anthropometric measurements, laboratory findings, and health risk differences to find an ideal BMI group according to the BMI charts. Methods Normal BMI according to adult classification from the World Health Organization (BMI at 18.5-24.9) is used as a reference group. Results & Conclusion Our study showed BMI value at 50th-74th percentiles in boys and at 75th-84th percentiles in girls had higher anthropometric measurements and laboratory findings than the reference group. However, the health risks of those BMI percentiles did not significant different compared with the reference group.
