- Objective: To investigate the current prevalence of physician-diagnosed obstructive airway diseases by respiratory symptoms and by sex in Sweden and Finland. Method: In 2016, a postal questionnaire was answered by 34,072 randomly selected adults in four study areas: Västra Götaland and Norrbotten in Sweden, and Seinäjoki-Vaasa and Helsinki in Finland. Results: The prevalence of asthma symptoms was higher in Norrbotten (13.2%), Seinäjoki-Vaasa (14.8%) and Helsinki (14.4%) than in Västra Götaland (10.7%), and physician-diagnosed asthma was highest in Norrbotten (13.0%) and least in Västra Götaland (10.1%). Chronic productive cough was most common in the Finnish areas (7.7-8.2 % versus 6.3-6.7 %) while the prevalence of physician-diagnosed chronic bronchitis (CB) or chronic obstructive pulmonary disease (COPD) varied between 1.7-2.7% in the four areas. Among individuals with respiratory symptoms, the prevalence of asthma was most common in Norrbotten, while a diagnosis of COPD or CB was most common in Västra Götaland and Seinäjoki-Vaasa. More women than men with respiratory symptoms reported a diagnosis of asthma in Sweden and Seinäjoki-Vaasa but there were no sex differences in Helsinki. In Sweden, more women than men with symptoms of cough or phlegm reported a diagnosis of CB or COPD, while in Finland the opposite was found. Conclusion: The prevalence of respiratory symptoms and corresponding diagnoses varied between and within the countries. The proportion reporting a diagnosis of obstructive airway disease among individuals with respiratory symptoms varied, indicating differences in diagnostic patterns both between areas and by sex.

- 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.

- Background: Chronic nonrespiratory diseases are seemingly more prevalent in subjects with than without asthma, and asthma seems to differentiate by age of onset. However, studies with comparison of nonrespiratory diseases in subjects with and without asthma, considering asthma age of onset, are scarce.Objective: To compare the quantity and type of chronic nonrespiratory diseases in adults with and without asthma considering age at asthma diagnosis.Methods: In 2016, a FinEsS questionnaire was sent to 16,000 20- to 69-year-old adults randomly selected in Helsinki and Western Finland populations. Physician-diagnosed asthma was categorized to early (0-11), intermediate (12-39), and late-diagnosed (40-69 years).Results: A total of 8199 (51.5%) responded, and 842 (10.3%) reported asthma and age at diagnosis. In age and sex-adjusted binary logistic regression model, the most represented nonrespiratory disease was treated gastroesophageal reflux disease in early-diagnosed (odds ratio, 1.93; 95% CI, 1.17-3.19; P =.011) and osteoporosis in both intermediate-diagnosed (odds ratio, 3.45; 95% CI, 2.01-5.91; P <.001) and late-diagnosed asthma (odds ratio, 2.91; 95% CI, 1.77-4.79; P <.001), compared with subjects without asthma. In addition, gastroesophageal reflux disease, depression, sleep apnea, painful condition, and obesity were significantly more common in intermediate- and late-diagnosed asthma compared with without asthma, and similarly anxiety or panic disorder in intermediate-diagnosed and hypertension, severe cardiovascular disease, arrhythmia, and diabetes in late-diagnosed asthma. In age-adjusted analyses, having 3 or more nonrespiratory diseases was more common in intermediate (12.1%) and late-diagnosed asthma (36.2%) versus without asthma (10.4%) (both P <.001).Conclusions: Nonrespiratory diseases were more common in adults with asthma than in adults without asthma. The type of nonrespiratory diseases differed, and their frequency increased by increasing age at asthma diagnosis.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Bronchial hyperresponsiveness (BHR) elevates the risk for development of respiratory symptoms and accelerates the decline in forced expiratory volume in the first second (FEV(1) ). We thus aimed to assess the prevalence, determinants and quantity of BHR in Helsinki. Objectives: This study involved 292 randomly selected subjects age 26-66years, women comprising 58%. Methods: Following a structured interview, a spirometry, a bronchodilation test, and a skin-prick test, we assessed a bronchial challenge test with inhaled histamine using a dosimetric tidal breathing method. Results included the provocative dose inducing a decrease in FEV(1) by 15% (PD(15) FEV(1) ) and the dose-response slope. For statistical risk factor-analyses, the severity of BHR was considered; PD(15) values ≤1.6mg (BHR) and ≤0.4mg [moderate or severe BHR (BHR(ms) )] served as cut-off levels. Results: BHR presented in 21.2% and BHR(ms) in 6.2% of the subjects. FEV(1) <80% of predicted [odds ratio (OR) 4.09], airway obstruction (FEV(1) /forced vital capacity<88% of predicted) (OR 4.33) and history of respiratory infection at age <5 (OR 2.65) yielded an increased risk for BHR as ORs in multivariate analysis. For BHR(ms) , the determinants were decreased FEV(1) below 80% of predicted (OR 27.18) and airway obstruction (OR 6.16). Respiratory symptoms and asthma medication showed a significant association with BHR. Conclusions: Of the adult population of Helsinki, 21% showed BHR to inhaled histamine. The main determinants were decreased FEV(1) and airway obstruction. Quantitative assessment of BHR by different cut-off levels provides a tool for characterization of phenotypes of airway disorders in epidemiologic and clinical studies.

- OBJECTIVE: To assess the relation of socio-economic status to respiratory symptoms common in asthma and chronic bronchitis, and to compare risk factors for these symptoms between three neighbouring countries. DESIGN: A postal survey was performed in 1996 as a part of comparative studies in Finland, Sweden and Estonia (the FinEsS studies). A random sample of 58,661 subjects aged 20-64 years were invited, of whom 44,483 participated. RESULTS: Respiratory symptoms were most prevalent among manual workers, who were at significantly increased risk for chronic respiratory symptoms. The same pattern of increased risk appeared when the analyses were made among non-smokers only: for recurrent wheeze, manual workers in industry yielded an OR of 1.91 (95%CI 1.62-2.24) and in the service sector an OR of 1.50 (95%CI 1.27-1.78). The corresponding figures for chronic productive cough were 1.45 (95%CI 1.22-1.71) and 1.20 (95%CI 1.02-1.42), respectively. Risk factor profiles for respiratory symptoms were similar in Finland, Sweden and Estonia, except for gender differences in Estonia.CONCLUSIONS: Belonging to the socio-economic group of manual workers correlated with an increased risk for chronic respiratory symptoms, independently of smoking habits, in each country. Women manual workers in industry suffered most from respiratory symptoms
