Abstract

The purpose of the study was to examine metabolic risk factors among 18 year old high-school students and compare students attending vocational and traditional schools. Participants (147 boys and 130 girls) were randomly selected. Physical activity (PA) was measured with pedometers and aerobic fitness (fitness) with maximal oxygen uptake test on a treadmill. Height, weight, waist circumference (WC), and body mass index (BMI) were measured and percentage body fat (%Fat) assessed with dual energy X-ray absorptiometry. Resting blood pressure (BP) and serum lipids and glucose were measured. According to BMI, 23% of the students were overweight/obese, 20% had elevated WC, and 51% increased %Fat. In addition, 11% of the students had high-density lipoprotein below recommended levels, and 8% had low-density lipoprotein and 9% triglycerides above advised values. Finally, 10% had borderline or high systolic BP. In contrast, 84% of the students had fair or higher levels of fitness, although on...
