    • The chronic impact of ambient air pollutants on lung function in adults is not fully understood. The objective of this study was to investigate the association of long-term exposure to ambient air pollution with lung function in adult participants from five cohorts in the European Study of Cohorts for Air Pollution Effects (ESCAPE). Residential exposure to nitrogen oxides (NO2, NOx) and particulate matter (PM) was modelled and traffic indicators were assessed in a standardised manner. The spirometric parameters forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) from 7613 subjects were considered as outcomes. Cohort-specific results were combined using meta-analysis. We did not observe an association of air pollution with longitudinal change in lung function, but we observed that a 10 μg·m(-3) increase in NO2 exposure was associated with lower levels of FEV1 (-14.0 mL, 95%CI -25.8- -2.1) and FVC (-14.9 mL, 95% CI -28.7- -1.1). An increase of 10 μg·m(-3) in PM10, but not other PM metrics (PM2.5, coarse fraction of PM, PM absorbance), was associated with a lower level of FEV1 (-44.6 mL, 95% CI -85.4- -3.8) and FVC (-59.0 mL, 95% CI -112.3- -5.6). The associations were particularly strong in obese persons. This study adds to the evidence for an adverse association of ambient air pollution with lung function in adults at very low levels in Europe.

  • Physical activity and incidence of restrictive spirometry pattern in adults
  • 2018
  • Ingår i: European Respiratory Journal. - : European Respiratory Society. - 0903-1936 .- 1399-3003. ; 52
  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • Introduction: A restrictive spirometry pattern is associated with high morbidity and mortality. Whether regular physical activity (PA) protects against this pattern has never been studied.Objective: To assess if PA is associated with the development of restrictive pattern.Methods: Lung function and PA were assessed in the second and third follow-up of the ECRHS (n=2757, 39-67 years) and SAPALDIA (n=2610, 36-82 y) cohorts. Subjects with restrictive or obstructive pattern at baseline were excluded. We assessed the association of being active at baseline (defined as exercising vigorously >2-3 times/wk for >1 h) and restrictive pattern at follow-up (defined as a post-bronchodilator FEV1/FVC≥LLN and FVC<80% pred.) using modified Poisson regression, adjusting for age, sex, smoking and asthma. We explored the impact of adjusting for baseline FVC. Additionally, models were repeated stratified by BMI.Results: After 10 years follow-up, 3.7% and 2.8% of participants developed a restrictive pattern, in ECRHS and SAPALDIA respectively. In both cohorts, being physically active was associated with lower risk of a restrictive pattern (meta-analysed RR 0.65, 95% CI 0.47-0.89). This association was stronger in overweight (0.41, 0.23-0.75) and obese (0.42, 0.17-1.05) than in normal weight subjects, but was attenuated when adjusting for baseline FVC (0.77, 0.58-1.04).Conclusion: In two large European studies, adults who reported more PA were at lower risk of developing a restrictive spirometry pattern. Lung function at baseline seemed to explain part of the observed association, stressing the need of adequate method to take into account both horse-racing and regression-to-the-means effects.

  • Asthma, COPD and overlap syndrome : a longitudinal study in young European adults
  • 2015
  • Ingår i: European Respiratory Journal. - : European Respiratory Society (ERS). - 0903-1936 .- 1399-3003. ; 46:3, s. 671-679
  • Tidskriftsartikel (refereegranskat)abstract
    • We compared risk factors and clinical characteristics, 9-year lung function change and hospitalisation risk across subjects with the asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS), asthma or COPD alone, or none of these diseases. Participants in the European Community Respiratory Health Survey in 1991-1993 (aged 20-44 years) and 1999-2001 were included. Chronic airflow obstruction was defined as pre-bronchodilator forced expiratory volume in 1 s (FEV1)/forced vital capacity

  • Health-related quality of life and risk factors associated with spirometric restriction
  • 2017
  • Ingår i: European Respiratory Journal. - : The European Respiratory Society. - 0903-1936 .- 1399-3003. ; 49:5
  • Tidskriftsartikel (refereegranskat)abstract
    • The restrictive spirometric pattern is associated with a substantial morbidity and mortality burden. We sought to determine to what extent spirometric restriction is associated with impaired quality of life.We used data from two large population-based European cohorts: 6698 European Community Respiratory Health Survey (ECRHS) and 6069 Swiss Cohort Study on Air Pollution and Lung and Heart Diseases in Adults (SAPALDIA) adult participants. The restrictive pattern was defined as forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) ≥lower limit of normal (LLN) and FVC 1/FVC In both cohorts, the restrictive pattern was associated with heavy smoking, being underweight or obese and the coexistence of respiratory symptoms. In univariate analyses, compared with the normal group, both the restrictive and obstructive pattern had significant Physical Component Summary deficits (−2.77 and −2.08, respectively, in ECRHS; −3.25 and −2.14, respectively, in SAPALDIA; all p-values <0.001). However, in models adjusted for sex, age, education, body mass index, smoking, comorbidities and respiratory symptoms, only the restrictive pattern remained significantly associated with Physical Component Summary deficits (p=0.004 in ECRHS; p=0.001 in SAPALDIA).The restrictive spirometric pattern is associated with deficits in the physical component of quality of life that are partly independent of the presence of respiratory symptoms.

  • Epigenome-wide association study of lung function level and its change
  • 2019
  • Ingår i: European Respiratory Journal. - : European Respiratory Society. - 0903-1936 .- 1399-3003. ; 54:1

    • Previous reports link differential DNA methylation (DNAme) to environmental exposures that are associated with lung function. Direct evidence on lung function DNAme is, however, limited. We undertook an agnostic epigenome-wide association study (EWAS) on pre-bronchodilation lung function and its change in adults.In a discovery-replication EWAS design, DNAme in blood and spirometry were measured twice, 6-15 years apart, in the same participants of three adult population-based discovery cohorts (n=2043). Associated DNAme markers (p<5×10-7) were tested in seven replication cohorts (adult: n=3327; childhood: n=420). Technical bias-adjusted residuals of a regression of the normalised absolute β-values on control probe-derived principle components were regressed on level and change of forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and their ratio (FEV1/FVC) in the covariate-adjusted discovery EWAS. Inverse-variance-weighted meta-analyses were performed on results from discovery and replication samples in all participants and never-smokers.EWAS signals were enriched for smoking-related DNAme. We replicated 57 lung function DNAme markers in adult, but not childhood samples, all previously associated with smoking. Markers not previously associated with smoking failed replication. cg05575921 (AHRR (aryl hydrocarbon receptor repressor)) showed the statistically most significant association with cross-sectional lung function (FEV1/FVC: pdiscovery=3.96×10-21 and pcombined=7.22×10-50). A score combining 10 DNAme markers previously reported to mediate the effect of smoking on lung function was associated with lung function (FEV1/FVC: p=2.65×10-20).Our results reveal that lung function-associated methylation signals in adults are predominantly smoking related, and possibly of clinical utility in identifying poor lung function and accelerated decline. Larger studies with more repeat time-points are needed to identify lung function DNAme in never-smokers and in children.

  • Effect of asthma on the development of obesity among adults : Results of the European Community Respiratory Health Survey (ECRHS)
  • 2018

    • Introduction: Obesity has been associated with asthma, however the reverse relation has recently been observed among children.Objective: To investigate whether asthma contributes to obesity incidence in adults.Methods: The ECRHS is a cohort study with two follow-ups around, 10-years (ECRHS-II) and 20-years (ECRHS-III) after enrolment. Participants with obesity (BMI>30kg/m2) at baseline were excluded (n=957), leaving 8618 non-obese subjects who participated in at least one follow-up. Asthmatics were described if the subjects reported ever having asthma and had an asthma attack or woke up by an attack of shortness of breath in last 12 months or on current asthma medication. We evaluated the association between: (1) asthma at baseline (ECRHS-I) and obesity at ECRHS-II; and (2) newly reported asthma at ECRHS-II and obesity at ECRHS-III.Results: 10.2% of asthmatics at baseline developed obesity after 10 years compared to 7.7% of non-asthmatics (Age, sex & country-adjusted relative risk: 1.26; 95% confidence interval: 1.03-1.55). Further adjustment for BMI at baseline slightly reduced this risk (RR:1.2; 95%CI: 1.0-1.4). Obesity risk was highest for those developing asthma in adulthood (RR:1.37; 95%CI: 1.01-1.86) compared to those with childhood onset asthma (RR: 1.13; 95%CI: 0.83-1.53). Asthmatics who were non-atopic at baseline had a higher risk of developing obesity at 1st follow up (RR: 1.47; 95%CI: 1.15-1.86). Similar trend was observed in newly reported asthmatics in ECRHS-II and increased obesity risk at the final follow up ECRHS-III (RR: 1.22; 95%CI: 0.86-1.73).Conclusion: These results suggest that asthmatics are at a higher risk of developing obesity.

  • Indoor bacteria and asthma in adults : a multicentre case-control study within ECRHS II
  • 2018
  • Ingår i: European Respiratory Journal. - : European Respiratory Society (ERS). - 0903-1936 .- 1399-3003. ; 51:2

    • Both protective and adverse effects of indoor microbial exposure on asthma have been reported, but mostly in children. To date, no study in adults has used non-targeted methods for detection of indoor bacteria followed by quantitative confirmation. A cross-sectional study of 198 asthmatic and 199 controls was conducted within the European Community Respiratory Health Survey (ECRHS) II. DNA was extracted from mattress dust for bacterial analysis using denaturing gradient gel electrophoresis (DGGE). Selected bands were sequenced and associations with asthma confirmed with four quantitative PCR (qPCR) assays. 15 out of 37 bands detected with DGGE, which had at least a suggestive association (p<0.25) with asthma, were sequenced. Of the four targeted qPCRs, Clostridium cluster XI confirmed the protective association with asthma. The association was dose dependent (aOR 0.43 (95% CI 0.22-0.84) for the fourth versus first quartile, p for trend 0.009) and independent of other microbial markers. Few significant associations were observed for the three other qPCRs used. In this large international study, the level of Clostridium cluster XI was independently associated with a lower risk of prevalent asthma. Results suggest the importance of environmental bacteria also in adult asthma, but need to be confirmed in future studies.
