Role of insulin resistance in non-obese adolescents.

Insulin resistance in the obese is closely related with cardiovascular diseases and their risk factors not only in adults but also in children and adolescents. We aimed to elucidate whether insulin resistance in non-obese adolescents is related with these conditions. A total of 74 non-obese high-school students (38 boys and 36 girls) were recruited.

Role of exercise in the prevention of obesity and hemodynamic abnormalities in adolescents.

Background: Poor physical activity plays a key role in the development of obesity. Little is known, however, about how much or the level of intensity of exercise that is needed to prevent obesity and hemodynamic abnormalities in adolescents.

Methods And Results: Height, bodyweight, resting heart rate (HR), and systolic and diastolic blood pressure was measured in 17,523 male and 16,906 female high school students.

Adolescent obesity adversely affects blood pressure and resting heart rate.

Background: Obesity is associated with hypertension (HT) and high resting heart rate (HR), as well as metabolic disturbances. However, little is known about how strongly these hemodynamic abnormalities are associated with the degree of obesity in adolescents.

Methods And Results: Height, body weight, resting HR, and systolic and diastolic blood pressures were measured in 20,165 male and 19,683 female high-school students.

Risk of obesity enhanced by poor physical activity in high school students.

Background: The aim of this study was to elucidate the interactions between a family history of obesity and poor physical activity.

Methods: A case-control study was performed based on medical check data for all first year high school students admitted to Aichi Prefectural public high schools in the 2004 academic year. Prior to the post-admission medical check up, all students received an interview sheet containing questions on family history of obesity and extent of physical activity.
