  1. aAsthma was defined as fulfilling at least 2 of 3 criteria: symptoms of wheeze and/or breathing difficulties in the preceding 12 months, ever doctor’s diagnosis of asthma and/or use of asthma medication occasionally or regularly in the preceding 12 months
  2. bUncontrolled asthma defined as at least 3 of 4 symptoms: at least 4 episodes of wheeze, any night-time awakening, activity limitation and use of a symptom reliever at least 2 times/week in the preceding 12 months
  3. cSelf-reported amount of physical activity in the preceding 12 months. Categorised as fulfilling the WHO recommendations where adults from 18 years should do ≥ 150 min/week of moderate to vigorous activity, or ≥ 75 min/week of vigorous activity
  4. dNever asthma: no occasion of asthma at earlier follow-ups. Adolescent-onset asthma: asthma at the 16- or 24-year follow-up, but not at earlier follow-ups. Persistent asthma: asthma at the 16- or 24-year follow-up and at least one earlier follow-up (1-, 2-, 4-, 8- or 12-year follow-ups)
  5. ep values indicate differences between crude median EuroQol visual analogue scale scores and asthma at the 24-year follow-up, obtained using quantile regression
  6. fp values indicate differences between adjusted median EuroQol visual analogue scale scores and asthma at the 24-year follow-up, obtained using quantile regression. Adjusted for sex, family history of allergic disease and socio-economic status
  7. gMissing values due to missing data of EuroQol visual analogue scale scores at 24-year follow-up or one or more of the confounding variables: sex, family history of allergic disease and socio-economic status
