RESUMO
AIM: To analyze, in a population of adolescents in school, the relationship between psychosomatic symptoms and the perception of health-related quality of life (HRQoL), differentiating by gender and age group. DESIGN: Transversal study. LOCATION: Five Secondary Schools. PARTICIPANTS: Eight hundred and forty four adolescents between the ages of 15 and 18 in secondary school. MAIN MEASUREMENTS: HRQoL using KIDSCREEN-52 and psychosomatic symptoms with the psychosomatic problems scale (PSP). RESULTS: Girls and adolescents aged 17-18 years presented significantly higher psychosomatic symptoms, both groups also scored worse in all dimensions of HRQoL, although only the dimensions related to physical and mental wellness, mood and stress reached significance. All psychosomatic symptoms were inversely associated with the ten dimensions of KIDSCREEN-52. The regression models showed that sadness, concentrating difficulties and sleeping difficulties were the predictors of worse HRQoL in both sexes and age groups and these variables explained between 30 and 41% of the HRQoL variance of the adolescents. CONCLUSIONS: Psychosomatic symptoms are frequent especially in girls and in older adolescents and predictors of worse HRQoL. It is important to distinguish them from medical conditions to avoid unnecessary interventions. As expressions of emotional discomfort they must be evaluated and treated in an integral way because they interfere with daily life and increase the vulnerability proper of adolescence.

PURPOSE: Our objective was to analyze the association between different intensities of physical activity (PA), physical fitness, and metabolic syndrome (MS) in young adults. METHODS: Cross-sectional study including 275 university students, 18-30 years old, from Cuenca, Spain. We evaluated (a) physical activity using accelerometry, (b) aerobic capacity (VO2max), and (c) muscle strength, by a muscle strength index calculated as the sum of the standardized z score of handgrip dynamometry/weight and standing broad jump. An MS index was estimated by summing standardized z scores of waist circumference, ratio of triglycerides to high-density lipoprotein, mean arterial blood pressure, and HOMA-IR. RESULTS: The mean scores of MS index and HOMAIR were significantly higher and the VO2max significantly lower for individuals who did not perform 20 min or more per week of vigorous physical activity. However, those who performed 250 min/week of moderate physical activity showed no significant differences in either VO2max or the MS index when compared with individuals who did not perform this level of activity. The MS index was lower in those with medium-high levels of aerobic capacity. In addition, individuals with medium-high levels of muscular fitness showed lower waist circumference and a lower MS index. CONCLUSIONS: VO2max and muscle strength are negatively associated with metabolic risk. 20-min/week of vigorous physical activity was associated with lower cardiometabolic risk in young adults; moderate physical activity did not show association with lower cardiometabolic risk.
