  • Breathlessness across generations : results from the RHINESSA generation study
  • 2022
  • Ingår i: Thorax. - : BMJ. - 0040-6376 .- 1468-3296. ; 77:2, s. 172-177
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Breathlessness is a major cause of suffering and disability globally. The symptom relates to multiple factors including asthma and lung function, which are influenced by hereditary factors. No study has evaluated potential inheritance of breathlessness itself across generations.Methods: We analysed the association between breathlessness in parents and their offspring in the Respiratory Health in Northern Europe, Spain and Australia generation study. Data on parents and offspring aged ≥18 years across 10 study centres in seven countries included demographics, self-reported breathlessness, asthma, depression, smoking, physical activity level, measured Body Mass Index and spirometry. Data were analysed using multivariable logistic regression accounting for clustering within centres and between siblings.Results: A total of 1720 parents (mean age at assessment 36 years, 55% mothers) and 2476 offspring (mean 30 years, 55% daughters) were included. Breathlessness was reported by 809 (32.7%) parents and 363 (14.7%) offspring. Factors independently associated with breathlessness in parents and offspring included obesity, current smoking, asthma, depression, lower lung function and female sex. After adjusting for potential confounders, parents with breathlessness were more likely to have offspring with breathlessness, adjusted OR 1.8 (95% CI 1.1 to 2.9). The association was not modified by sex of the parent or offspring.Conclusion: Parents with breathlessness were more likely to have children who developed breathlessness, after adjusting for asthma, lung function, obesity, smoking, depression and female sex in both generations. The hereditary components of breathlessness need to be further explored.

  • Heritability of cough across two generations : the RHINESSA study.
  • 2024
  • Ingår i: ERJ open research. - : European Respiratory Society. - 2312-0541. ; 10:4
  • Tidskriftsartikel (refereegranskat)abstract
    • AIM: Heritability of cough has not yet been studied. We aimed to evaluate if individuals with cough are more likely to have offspring who develop cough, and if these associations differ by type of cough (productive/nonproductive).METHODS: The RHINESSA Generation Study (Respiratory Health In Northern Europe, Spain and Australia) includes 7155 parents (initially aged 30-54) answering detailed questionnaires in 2000 and 2010, and 8176 offspring ≥20 years answering similar questionnaires in 2012-2019. Chronic cough was categorised as productive or nonproductive (dry) cough. Associations between parental and offspring cough were analysed using mixed-effects logistic regression, adjusting for offspring age, sex, body mass index, smoking history, education level, current asthma, rhinitis, nocturnal gastroesophageal reflux; parent sex and smoking history; centre and family.RESULTS: Among parents with nonproductive cough, 11% of their offspring reported nonproductive cough, compared with 7% of offspring to parents without nonproductive cough, adjusted odds ratio (aOR) 1.59 (95% confidence interval 1.20-2.10). Among parents with productive cough, 14% of their offspring reported productive cough, compared with 11% of offspring to parents without productive cough, aOR 1.34 (1.07-1.67). No associations were found between parent productive cough-offspring nonproductive cough, nor between parent nonproductive cough-offspring productive cough.CONCLUSIONS: Parents with chronic cough are more likely to have offspring with chronic cough independent of parental asthma, suggesting cough to be a separate heritable trait. The type of cough is important, as the nonproductive cough in parent associates only with nonproductive cough in offspring, and the same applied for productive cough.

  • Snoring and nocturnal reflux : association with lung function decline and respiratory symptoms
  • 2019
  • Ingår i: ERJ Open Research. - : European Respitory Society (ERS). - 2312-0541. ; 5:2
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: The study aim was to examine the association of snoring and nocturnal gastro-oesophageal reflux (nGOR) with respiratory symptoms and lung function, and if snoring and/or nGOR associated with a steeper decline in lung function. Methods: Data from the third visit of the European Community Respiratory Health Survey (ECRHS) was used for cross-sectional analysis. Pre- and post-bronchodilator spirometry was performed, and information on sleep, nGOR and respiratory symptoms was collected (n=5715). Habitual snoring and nGOR were assessed by questionnaire reports. Pre-bronchodilator spirometry from ECRHS I, II and III (20 years follow-up) were used to analyse lung function changes by multivariate regression analysis. Results: Snoring and nGOR were independently associated with a higher prevalence of wheeze, chest tightness, breathlessness, cough and phlegm. The prevalence of any respiratory symptom was 79% in subjects with both snoring and nGOR versus 56% in those with neither (p<0.001). Subjects with both snoring and nGOR had more frequent exacerbations (adjusted prevalence 32% versus 19% among "no snoring, no nGOR", p=0.003). Snoring but not nGOR was associated with a steeper decline in forced expiratory volume in 1 s over 10 years after adjusting for confounding factors (change in % predicted -5.53, versus -4.58 among "no snoring", p=0.04) and forced vital capacity (change in % predicted -1.94, versus -0.99 among "no snoring", p=0.03). Conclusions: Adults reporting both habitual snoring and nGOR had more respiratory symptoms and more frequent exacerbations of these symptoms. Habitual snoring was associated with a steeper decline in lung function over time.

  • Clinical remission of asthma and allergic rhinitis : in a longitudinal population study
  • 2022
  • Ingår i: Journal of Asthma and Allergy. - : Dove press. - 1178-6965. ; 15, s. 1569-1578
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Although asthma and allergic rhinitis are chronic diseases, some patients experience periods of remission. Information on prognostic factors associated with the remission of asthma and allergic rhinitis is valuable in resource prioritization. This study investigated factors associated with the clinical remission of asthma and allergic rhinitis.Methods: In the Respiratory Health In Northern Europe (RHINE) study, data was collected with questionnaires in stage one (RHINE I, 1989–1992) and two follow-ups (RHINE II, 1999–2001 and RHINE III, 2010–2012) from Sweden, Norway, Denmark, Iceland and Estonia. Clinical remission was defined as having reported asthma or allergic rhinitis in RHINE I or RHINE II but not in RHINE III.Results: Of 13,052 participants, 975 (7.5%) reported asthma in RHINE I or RHINE II, and 3379 (25.9%) allergic rhinitis. Clinical remission of asthma and allergic rhinitis was found in 46.4% and 31.8%, respectively. Living in Estonia (OR (95% CI) 2.44 (1.22– 4.85)) and living in an apartment (1.45 (1.06–1.98)) were related to remission of asthma, while subjects reporting allergic rhinitis (0.68 (0.51–0.90)), asthma onset ≤ 12 years of age (0.49 (0.35–0.68)), receiving treatment with antibiotics for respiratory illness (0.64 (0.47– 0.87)) were less likely to have asthma remission. Factors related to a higher likelihood of remission of allergic rhinitis were no asthma at baseline, age ≥ 58 years in RHINE III, allergic rhinitis onset after 12 years of age, living in rural areas as a child, having only a primary school education and not being pregnant.Conclusion: Clinical remission was found in almost one-half of those with asthma and one-third of persons with allergic rhinitis. Coexisting allergic symptoms were associated with less clinical asthma remission. Age, asthma symptoms and environmental factors in childhood, such as living in a rural area, were found to influence the clinical remission of allergic rhinitis.

  • Change in the prevalence asthma, rhinitis and respiratory symptom over a 20 year period : associations to year of birth, life style and sleep related symptoms
  • 2018
  • Ingår i: BMC Pulmonary Medicine. - : BioMed Central. - 1471-2466. ; 18
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The aim of this investigation was to study change in adults over a 20 year period in the prevalence of respiratory symptoms and disorders and its association to year of birth, life style and sleep related variables.Method: Adults 20-44 years of age, 6085 women and 5184 men, were randomly selected from seven centres in Northern Europe and followed for 20 years. The number of participants in the first survey was 21,595 and 11,269 participated in all three surveys. The participants were divided into three birth cohorts: 1944-1955, 1956-1965 and 1966-1975.Results: During the 20 year period the prevalence of wheeze decreased (-2%) and the prevalence of asthma (+ 4%) and allergic rhinitis (+ 5%) increased, whereas the prevalence of nocturnal respiratory symptoms was relatively unchanged. The increase in allergic rhinitis was largest in those born 1966 to 1975 except in Estonia. There was large decrease in smoking (-20%), increase in obesity (+ 7%) and snoring (+ 6%) during the study period. Smoking, obesity, snoring and nocturnal gastroesophageal reflux (nGER) were related to a higher risk of all symptoms. Obesity, snoring and nGER were also independently related to asthma.Conclusion: We conclude that as our participants got older there was a decrease in wheeze, no change in nocturnal symptoms and an increase in reported asthma and allergic rhinitis. These changes in prevalence are probably related to a decrease in smoking being counteracted by an increase in allergy, obesity and sleep related disorders.

  • Long-term air pollution exposure is associated with sick leave 20 years later
  • 2018
  • Ingår i: European Respiratory Journal. - : European Respiratory Society. - 0903-1936 .- 1399-3003. ; 52
  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • Background: Little is known on outdoor air pollution in a long-term perspective and societal costs such as sick leave. In the Nordic countries, recent pollution health impact assessments have had to rely on outdated studies.Aims: To investigate if air pollution exposure is associated with sick leave 20 years later.Methods: We analysed self-reported sick leave (all-cause and respiratory) in 7 466 subjects from Bergen, Gothenburg, Umea, Uppsala in the RHINE3 study in 2010-12. Home addresses were geocoded and linked to annual average concentrations of PM2.5, PM10 and NO2 at RHINE3, 10 years earlier and 20 years earlier, using existing land-use regression (LUR) models. We performed multilevel logistic regression clustered by centre, and adjusted for sex, smoking, education and previous health-related workplace change.Results: Age range in RHINE3 was 40-66 yrs, 34% and 4% reported all-cause and respiratory sick leave during the last year. In the adjusted analyses all-cause sick leave was associated with PM2.520 years earlier (OR per interquartile range (IQR) difference (2.6 µg/m³) 1.12 (95%CI 1.01, 1.24)), and borderline with NO2 (OR per IQR diff (8.1 µg/m³) 1.09 (95%CI 0.99, 1.19)). Respiratory sick leave was associated with PM10 20 years earlier (OR per IQR diff (3.92 µg/m³) 1.54 (95%CI 1.06, 2.25)), and borderline with PM2.5 (OR per IQR diff 1.31 (95%CI 0.97, 1.76)). Pollution exposures at present as well as 10 years earlier were not significantly associated with sick leave.Conclusions: Air pollution exposure in a general population is associated with sick leave in a 20-year perspective. Our findings suggest that even low air pollution levels such as in Northern Europe have societal costs over time.

  • Association between abdominal and general obesity and respiratory symptoms, asthma and COPD : Results from the RHINE study
  • 2023
  • Ingår i: Respiratory Medicine. - : Elsevier. - 0954-6111 .- 1532-3064. ; 211
  • Tidskriftsartikel (refereegranskat)abstract
    • IntroductionPrevious studies on the association between abdominal and general obesity and respiratory disease have provided conflicting results.Aims and objectivesWe aimed to explore the associations of abdominal obesity with respiratory symptoms, asthma, and chronic obstructive pulmonary disease independently from general obesity in women and men.MethodsThis cross-sectional study was based on the Respiratory Health in Northern Europe (RHINE) III questionnaire (n = 12 290) conducted in 2010–2012. Abdominal obesity was self-measured waist circumference using a sex-specific standard cut-off point: ≥102 cm in males and ≥88 cm in females. General obesity was defined as self-reported BMI ≥30.0 kg/m2.ResultsThere were 4261 subjects (63% women) with abdominal obesity and 1837 subjects (50% women) with general obesity. Both abdominal and general obesity was independent of each other and associated with respiratory symptoms (odds ratio (OR) from 1.25 to 2.00)). Asthma was significantly associated with abdominal and general obesity in women, OR (95% CI) 1.56 (1.30–1.87) and 1.95 (1.56–2.43), respectively, but not in men, OR 1.22 (0.97–3.17) and 1.28 (0.97–1.68) respectively. A similar sex difference was found for self-reported chronic obstructive pulmonary disease.ConclusionsGeneral and abdominal obesity were independent factors associated with respiratory symptoms in adults. Asthma and chronic obstructive pulmonary disease were independently linked to abdominal and general obesity in women but not men.

  • Isolated small airways obstruction predicts future chronic airflow obstruction : a multinational longitudinal study
  • 2023
  • Ingår i: BMJ Open Respiratory Research. - : BMJ Publishing Group Ltd. - 2052-4439. ; 10:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Chronic airflow obstruction is a key characteristic of chronic obstructive pulmonary disease. We investigated whether isolated small airways obstruction is associated with chronic airflow obstruction later in life.METHODS: We used longitudinal data from 3957 participants of the multinational Burden of Obstructive Lung Disease study. We defined isolated small airways obstruction using the prebronchodilator mean forced expiratory flow rate between 25% and 75% of the forced vital capacity (FVC) (FEF25-75) if a result was less than the lower limit of normal (1/FVC). We also used the forced expiratory volume in 3 s to FVC ratio (FEV3/FVC) to define small airways obstruction. We defined chronic airflow obstruction as post-bronchodilator FEV1/FVCRESULTS: Median follow-up time was 8.3 years. Chronic airflow obstruction was more likely to develop in participants with isolated small airways obstruction at baseline (FEF25-75 less than the LLN, OR: 2.95, 95% CI 1.02 to 8.54; FEV3/FVC less than the LLN, OR: 1.94, 95% CI 1.05 to 3.62). FEF25-75 was better than the FEV3/FVC ratio to discriminate future chronic airflow obstruction (AUC: 0.764 vs 0.692). Results were similar among participants of the UK Biobank study.CONCLUSION: Measurements of small airways obstruction can be used as early markers of future obstructive lung disease.

  • Lung health in adulthood after childhood exposure to air pollution and greenness
  • 2018
  • Ingår i: European Respiratory Journal. - : European Respiratory Society. - 0903-1936 .- 1399-3003. ; 52
  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • Background: Little is known on childhood exposure to air pollution and adult chronic respiratory outcomes.Aim: To investigate associations between air pollution and greenness in childhood and adult lung health.Methods: In selected centres of the RHINESSA study (age 18-52) we analysed the outcomes respiratory symptoms (≥3 symptoms), severe wheeze (wheeze last year with breathlessness, no cold) and late onset asthma (>10 years). We calculated mean annual exposures of PM2.5, PM10, NO2 (µg/m³) and greenness (Normalized Difference Vegetation Index, 100m buffer) from offspring's birth till age 18, categorised into mean exposure <10 years and 11-18 years. We performed multilevel logistic regression clustered by family, stratified by centre and adjusted for childhood passive smoke and parental asthma.Results: 12% had ≥3 respiratory symptoms, 7.7% severe wheeze, and 9.4% late onset asthma. Overall estimates: greenness was associated with less respiratory symptoms, PM2.5 and NO2 with more late onset asthma. Exposure <10 years: Greenness was associated with less wheeze in Tartu (OR 0.29, 95%CI 0.11-0.73). PM2.5 (OR 1.22, 95%CI 1.00-1.48) and NO2 (OR 1.06, 95%CI 1.01-1.11) were risk factors for late onset asthma in Bergen. PM10 was a risk factor for respiratory symptoms (OR 1.21, 95%CI 1.04-1.41) in Uppsala and late onset asthma (OR 1.23, 95%CI 1.02-1.45) in Bergen. Exposure 11-18 years: Greenness was protective for respiratory symptoms (OR 0.29, 95%CI 0.10-0.86) and wheeze (OR 0.39, 95%CI 0.19-0.80) in Tartu.Conclusions: Childhood exposure to greenness was associated with less respiratory symptoms, while air pollutants were associated with more respiratory symptoms (some centres) and late onset asthma.
