In addition recent studies have observed that gender differences in the health related quality of life HRQoL impact of LEs might be lower than believed. We assessed the relationship between LEs and HRQoL in a representative sample of Spanish adolescents youths focusing on gender differences. Methods Participants n 840 completed the KIDSCREEN-27 to measure HRQoL at baseline and again after 3 years n 454 . Follow-up assessment included the Coddington Life Events Scales CLES to measure LEs experiences in the previous 12 months. Respondents were categorized according to the amount of stress suffered. We calculated both the number of LEs and the Life Change Unit LCU score a summary of the amount of stress inherent to the event and the time elapsed since occurrence. LEs were classified as desirable or undesirable and family-related or extra-family. Effect sizes were calculated to evaluate changes in HRQoL. To assess the impact of LEs typologies multiple linear regression models were constructed to evaluate their effect on HRQoL. Results Girls reported a mean 5.7 LEs corresponding to 141 LCUs and boys 5.3 and 129 respectively. The largest impact of LEs on HRQoL was observed in the group of boys that reported to have lived more stress third tertil of LCUs distribution . The linear .
