  • Menstrual irregularity and asthma and lung function
  • 2007
  • Ingår i: Journal of Allergy and Clinical Immunology. - : Elsevier BV. - 0091-6749 .- 1097-6825. ; 120:3, s. 557-564
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Oligomenorrhea was associated with more asthma (Respiratory Health in Northern Europe study), but a possible association with lung function has not been investigated previously. Objective: To investigate whether oligomenorrhea was related to lung function and asthma, and whether body mass index and physical activity modified associations. Methods: Women age 28 to 44 years (n = 1631) participating in the European Community Respiratory Health Survey were included. Women who were taking exogenous sex hormones, were pregnant, or had recently given birth were excluded. Results: Long or irregular menstrual cycles were reported by 313 women (19%). Oligomenorrhea was significantly associated with more asthma symptoms (odds ratio [OR], 1.76; 95% CI, 1.29-2.40), allergic asthma (OR, 2.46; 95% CI, 1.43-4.23), and lower forced vital capacity (FVC; adjusted difference, 63 mL; 95% CI, -124 to -1). When excluding women using asthma medication, very lean women, or women exercising daily, these associations remained significant. Effects of oligomenorrhea were additive to those of body mass index (BMI) on asthma and FVC. Asthma symptoms increased significantly with BMI. FVC and FEV1 increased with BMI until 25 kg/m2 and thereafter decreased with increasing BMI. Excluding women exercising daily, asthma symptoms increased significantly with decreasing physical activity (OR, 1.09; 95% CI, 1.001-1.19) per category of physical activity) independently of oligomenorrhea. Among women exercising daily, oligomenorrhea predicted very high risk for asthma symptoms (OR, 12.6; 95% CI, 3.7-43). Conclusion: Women with oligomenorrhea have reduced lung function and more asthma, particularly allergic asthma, independent of BMI and physical activity. Airways pathology may have not only a hormonal but also a metabolic component. Clinical implications: Women with oligomenorrhea should be investigated with regard to asthma and lung function. Underlying metabolic disturbance should be considered in asthma.

  • Exposure to substances in the workplace and new-onset asthma : an international prospective population-based study (ECRHS-II)
  • 2007
  • Ingår i: The Lancet. - 0140-6736 .- 1474-547X. ; 370:9584, s. 336-341
  • Tidskriftsartikel (refereegranskat)abstract
    • Background The role of exposure to substances in the workplace in new-onset asthma is not well characterised in population-based studies. We therefore aimed to estimate the relative and attributable risks of new-onset asthma in relation to occupations, work-related exposures, and inhalation accidents. Methods We studied prospectively 6837 participants from 13 countries who previously took part in the European Community Respiratory Health Survey (1990-95) and did not report respiratory symptoms or a history of asthma at the time of the first study. Asthma was assessed by methacholine challenge test and by questionnaire data on asthma symptoms. Exposures were defined by high-risk occupations, an asthma-specific job exposure matrix with additional expert judgment, and through self-report of acute inhalation events. Relative risks for new onset asthma were calculated with log-binomial models adjusted for age, sex, smoking, and study Centre. Findings A significant excess asthma risk was seen after exposure to substances known to cause occupational asthma (Relative risk=1.6, 95% CI 1.1-2.3, p=0.017). Risks were highest for asthma defined by bronchial hyper-reactivity in addition to symptoms (2.4,1.3-4.6, p=0.008). Of common occupations, a significant excess risk of asthma was seen for nursing (2.2,1.3-4.0, p=0.007). Asthma risk was also increased in participants who reported an acute symptomatic inhalation event such as fire, mixing cleaning products, or chemical spills (RR=3.3, 95% CI 1.0-11.1, p=0.051). The population-attributable risk for adult asthma due to occupational exposures ranged from 10% to 25%, equivalent to an incidence of new-onset occupational asthma of 250-300 cases per million people per year. Interpretation Occupational exposures account for a substantial proportion of adult asthma incidence. The increased risk of asthma after inhalation accidents suggests that workers who have such accidents should be monitored closely.

  • Employment status and use of respiratory protection among metalworkers, solderers and welders
  • 2007
  • Ingår i: Occupational and Environmental Medicine. - : BMJ. - 1351-0711 .- 1470-7926. ; 64:8, s. 548-552
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: Reported associations of self-employment with occupational injury and cerebrovascular disease suggest that worker safety and health precautions may vary by occupational status. The authors assessed the extent to which use of respiratory protection and ventilation equipment is associated with self-employed versus employee status among adults in an international study. Methods: The European Community Respiratory Health Survey II (ECRHS II) is a follow-up study conducted in a population-based random sample of adult ECRHS I participants. Men and women enrolled in the ECRHS II completed interviewer-administered questionnaires to provide information about their occupational status and job history during the 9-year ECRHS follow-up period. Respondents in selected occupational groups completed supplemental questionnaires about their jobs and use of respiratory protection and ventilation equipment on-the-job. The authors assessed self-reported use of respiratory and ventilation equipment among 72 self-employed and 371 employed adults in metalworking, soldering and welding occupations. Results: Local exhaust ventilation (fixed extraction: OR 0.37, 95% Cl 0.17 to 0.80; mobile extraction: OR 0.23, 95% Cl 0.09 to 0.60; on-tool extraction: OR 0.39, 95% Cl 0.18 to 0.88) was reported less frequently among self-employed respondents than among employed respondents. The magnitude of the negative association between self-employment status and any of the three types of local exhaust ventilation was not attenuated by adjustment for duration of work per day or week or asthma and/or wheezing symptoms. Respiratory protection was not associated with employment status in these data. Conclusions: More limited use of local exhaust ventilation among self-employed workers compared to employees suggests the need to promote occupational safety among self-employed workers.

  • Occupational risk factors for asthma among nurses and related healthcare professionals in an international study
  • 2007
  • Ingår i: Occupational and Environmental Medicine. - : BMJ. - 1351-0711 .- 1470-7926. ; 64:7, s. 474-479
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: The authors examined the relations between self-reported work tasks, use of cleaning products and latex glove use with new-onset asthma among nurses and other healthcare workers in the European Community Respiratory Health Survey (ECRHS II). Methods: In a random population sample of adults from 22 European sites, 332 participants reported working in nursing and other related healthcare jobs during the nine-year ECRHS II follow-up period and responded to a supplemental questionnaire about their principal work settings, occupational tasks, products used at work and respiratory symptoms. Poisson regression models with robust error variances were used to compare the risk of new-onset asthma among healthcare workers with each exposure to that of respondents who reported professional or administrative occupations during the entire follow-up period (n=2481). Results: Twenty (6%) healthcare workers and 131 (5%) members of the referent population reported new-onset asthma. Compared to the referent group, the authors observed increased risks among hospital technicians (RR 4.63; 95% Cl 1.87 to 11.5) and among those using ammonia and/or bleach at work (RR 2.16; 95% Cl 1.03 to 4.53). Conclusions: In the ECRHS II cohort, hospital technicians and other healthcare workers experience increased risks of new-onset current asthma, possibly due to specific products used at work.

  • The use of household cleaning sprays and adult asthma : an international longitudinal study
  • 2007
  • Ingår i: American Journal of Respiratory and Critical Care Medicine. - 1073-449X .- 1535-4970. ; 176:8, s. 735-741
  • Tidskriftsartikel (refereegranskat)abstract
    • Rationale: Cleaning work and professional use of certain cleaning products have been associated with asthma, but respiratory effects of nonprofessional home cleaning have rarely been studied. Objectives: To investigate the risk of new-onset asthma in relation to the use of common household cleaners. Methods: Within the follow-up of the European Community Respiratory Health Survey in 10 countries, we identified 3,503 persons doing the cleaning in their homes and who were free of asthma at baseline. Frequency of use of 15 types of cleaning products was obtained in a face-to-face interview at follow-up. We studied the incidence of asthma defined as physician diagnosis and as symptoms or medication usage at follow-up. Associations between asthma and the use of cleaning products were evaluated using multivariable Cox proportional hazards or log-binomial regression analysis. Measurements and Main Results: The use of cleaning sprays at least weekly (42% of participants) was associated with the incidence of asthma symptoms or medication (relative risk [RR], 1.49; 95% confidence interval [Cl], 1.12-1.99) and wheeze (RR, 1.39; 95% Cl, 1.06-1.80). The incidence of physician-diagnosed asthma was higher among those using sprays at least 4 days per week (RR, 2.11; 95% Cl, 1.15-3.89). These associations were consistent for subgroups and not modified by atopy. Dose-response relationships (P < 0.05) were apparent for the frequency of use and the number of different sprays. Risks were predominantly found for the commonly used glass-cleaning, furniture, and air-refreshing sprays. Cleaning products not applied in spray form were not associated with asthma. Conclusions: Frequent use of common household cleaning sprays may be an important risk factor for adult asthma.
