Abstract [en]

Background: Overweight and mental illness among adolescents are big concerns in the society today. Health among adolescents is therefore an important area to study and this can be done by testing different physical performances or by using methods involving more psychological and social components. The view of health has during the last decades developed and become more complex, which has led to some change in criteria when evaluating health in people. The new viewpoint has more focus on functioning and daily living in individuals. The concept of this multi-criteria assessment is being referred to as health-related quality of life (HRQoL) and is considered an important aspect in research regarding public health and medical as well as psychosocial treatments among adolescents. Aim: The aim of the study was to investigate HRQoL among seventh grade students, to examine how HRQoL affected muscle strength and sprint ability and to investigate the correlation between muscle strength and sprint ability. Methods: HRQoL among the subjects (N = 64; boys = 44; girls = 20) was measured with the EQ-5D-3L questionnaire. A syntax was used to transcribe the responses to index values, which indicated the health state of the individuals. Muscle strength was measured from handgrip strength (HGS) with a hand dynamometer. Relative HGS (kg/kg BW) was calculated by dividing absolute strength (kg) with subjects’ bodyweight (kg). Sprint ability was measured from a 20 m sprint test performed in a gymnasium between four pairs of timing gates. The timing gates had a single infrared beam and were placed at 0 m, 5 m, 10 m and 20 m with a 2 m space between each pair. Results: 33.3% evaluated their own health as complete and the median index value for the entire group was 0.80 and mean ± SD were 0.83 ± 0.16. There was a small non-significant linear correlation between the index values from EQ-5D-3L and HGS (r = 0.13, p = 0.32, r2 = 0.02). No linear correlation between the index values from EQ-5D-3L and sprint times was seen (r = -0.06, p = 0.72, r2 = 0.003). There was a significant and negative medium linear correlation between HGS (kg/kg BW) and sprint times (s) (r = -0.30, p = 0.05, r2 = 0.01). Conclusion: One third of the subjects evaluated their own health as complete. There was a small, non-significant linear correlation between HRQoL and muscle strength and no linear correlation between HRQoL and sprint ability. The results also showed a significant and negative linear correlation between muscle strength and sprint times.
