Aim: This study examined the health-related quality of life (HRQoL) of teenagers with and without asthma, including the impact of their sex, allergic conditions, smoking, living conditions and physical activity.
Methods: The Obstructive Lung Disease in Northern Sweden (OLIN) studies recruited a cohort of schoolchildren in 2006. The parents of all children aged seven to eight years in three municipalities were invited to complete a questionnaire and 2585 (96%) participated. The cohort was followed up at the ages of 11-12 years and 14-15 years with high participation rates. At 14-15 years, the HRQoL questionnaire KIDSCREEN-10 and Asthma Control Test were added.
Results: Girls with current asthma at 14-15 years had a lower mean HRQoL score than girls without asthma (46.4 versus 49.3, p < 0.001), but this was not seen among boys (53.8 versus 52.8, p = 0.373). Poor HRQoL was related to current asthma, uncontrolled asthma and teenage onset of asthma. It was also related to eczema, living in a single-parent household, maternal smoking, daily smoking and inversely related to physical activity.
Conclusion: Teenage girls with asthma had lower HRQoL than girls without asthma. Possible interventions to improve HRQoL among teenagers with asthma were identified as follows: increasing asthma control, preventing smoking and promoting physical activity.
