- Background: Asthma may begin at any age. However, knowledge about the relationship between age at asthma diagnosis and asthma symptoms is still scarce.Objectives: To test the hypothesis that among adults, asthma diagnosed in adulthood is associated with more symptoms than asthma diagnosed in childhood.Methods: A FinEsS postal survey was conducted in a random sample of 16000 20-69-year-old adults in Finland in 2016. Age 18 years was chosen to delineate child and adult-diagnosed asthma. Current asthma was defined as physician-diagnosed asthma and asthma medication use, attacks of breathlessness or wheezing in the past year.Results: Of responders (8199, 51,5%), 692 reported current asthma and age at diagnosis. Adult-diagnosed asthma was reported by 445 (64.3%) and child-diagnosed by 247 (35.7%) responders. Those with adult-diagnosed asthma had more attacks of breathlessness in the past year (82.9% vs. 74.1%, p=0.006), dyspnea (mMRC grade ≥2) (34.4% vs. 18.8%, p<0.001) and sputum production in the past three consecutive months (40.0% vs. 27.5%, p=0.001). Of responders with adult and child-diagnosed asthma, 22.5% and 28.3% were current smokers, and 91.7% and 84.2% used asthma medication, respectively. In a logistic regression model, risk factors for attacks of breathlessness were adult-diagnosis (OR=1.8, 95% CI 1.1-3.0) and exercising <2 times a week (OR=2.0, 1.2-3.2).Conclusion: Asthmatics with adult-diagnosed asthma had significantly more symptoms even though they smoked less and used asthma medication more often compared to those with child-diagnosed asthma. Recognizing adult onset asthma in clinical practise is important to direct precise clinical care and achieve better asthma control.

- Background: Child-onset asthma is known to remit with high probability but remission in adult-onset asthma seems to be less common. Reports of association between remission and asthma onset age in adulthood are scarce.Objectives: To study if age at asthma diagnosis and gender are associated to remission rate in adult asthma population.Methods: In 2016, a random sample of 16 000 subjects aged 20-69 years from Helsinki and Western Finland were sent a FinEsS-questionnaire. Asthma was categorized by reported age when diagnosed with asthma by a physician: child (0-11 years) adolescent-young-adult (12-39 years) and late-adult-diagnosed (40-69 years). Remission was defined as a physician diagnosed asthma but not having had asthma symptoms, wheezing or use of asthma medication in the past 12 months.Results: 8199 subjects (51.5%) responded to the postal questionnaire. Remission was most common in child-diagnosed (30.2%), followed by adolescent-young-adult-diagnosed (17.9%) and least common in late-adult-diagnosed asthma (5.0%) (p<0.001). In males, the corresponding proportions were 36.7%, 20.0% and 3.4%, and in females 20.4%, 16.6% and 5.9%, respectively (p<0.001 for gender difference). In binary logistic regression, significant risk factors of non-remission were diagnosis at adolescent-young-adulthood- (OR=2.2, 95% CI 1.4-3.4) or late-adulthood- (OR=11.1, 4.8-25.4), asthma-COPD overlap (ACO) (OR=5.6, 1.3-24.5), allergic rhinitis (OR=2.3, 1.5-3.5) and family history of asthma (OR=1.9, 1.2-2.8). Results remained similar after exclusion of ACO.Conclusion: Remission was rare (5%) in adults diagnosed with asthma after age 40 years in both sexes. Causes of poor prognosis in adult-onset asthma need to be further elucidated.
