MATERIAL AND METHODS: 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. RESULTS: 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 only 34% reached recommended levels of daily PA. According to %Fat, a higher proportion of boys (33%) than girls (22%) were classified as obese (p=0.042) but a higher proportion of boys (57%) were very fit (57 vs. 24%, p<<0.001). Vocational students had lower levels of fitness (Cohen´s d (Cd)=0.7) and PA (Cd=0.7), and higher %Fat (Cd=0.5), WC (Cd=0.6), and BP (Cd=0.3, p<0.05). CONCLUSION: Although fitness among 18 year old Icelandic high-school students seems generally good, their PA is low and %Fat elevated. Serum lipids and systolic BP are also increased in about 10% of the teenagers. Vocational students measure worse on most metabolic risk factors than traditional students.
