- To investigate the association between occupational exposure and chronic rhinosinusitis.A random population from the region of Telemark, aged 16-50, answered a respiratory questionnaire including questions on chronic rhinosinusitis and exposure in the occupational environment.A total of 16,099/48,142 subjects responded. The prevalence of chronic rhinosinusitis was 9%. Exposure associated with chronic rhinosinusitis comprised paper dust (OR 1.3, 95% CI 1.1, 1.5), cleaning agents (OR 1.2, CI 1.0, 1.3), metal dust (OR 1.3, CI 1.1, 1.6), animals (OR 1.2, CI 1.0, 1.5), moisture/mould/mildew (OR 1.3, CI 1.1, 1.5) and physically strenuous work (OR 1.4, CI 1.2, 1.7).Occupational exposure to paper dust, cleaning agents, metal dust, animals, moisture/mould/mildew and physically strenuous work was independently related to having chronic rhinosinusitis. An occupational history should be reviewed when assessing patients with chronic rhinosinusitis.

- ObjectivesThis study aimed to characterise participants lost to follow-up and identify possible factors associated with non-participation in a prospective population-based study of respiratory health in Norway. We also aimed to analyse the impact of potentially biased risk estimates associated with a high proportion of non-responders.DesignProspective 5-year follow-up study.SettingRandomly selected inhabitants from the general population of Telemark County in south-eastern Norway were invited to fill in a postal questionnaire in 2013. Responders in 2013 were followed-up in 2018.Participants16 099 participants aged 16-50 years completed the baseline study. 7958 responded at the 5-year follow-up, while 7723 did not.Main outcome measures chi(2) test was performed to compare demographic and respiratory health-related characteristics between those who participated in 2018 and those who were lost to follow-up. Adjusted multivariable logistic regression models were used to assess the relationship between loss to follow-up, background variables, respiratory symptoms, occupational exposure and interactions, and to analyse whether loss to follow-up leads to biased risk estimates.Results7723 (49%) participants were lost to follow-up. Loss to follow-up was significantly higher for male participants, those in the youngest age group (16-30 years), those in lowest education level category and among current smokers (all p<0.001). In multivariable logistic regression analysis, loss to follow-up was significantly associated with unemployment (OR 1.34, 95%CI 1.22 to 1.46), reduced work ability (1.48, 1.35 to 1.60), asthma (1.22, 1.10 to 1.35), being woken by chest tightness (1.22, 1.11 to 1.34) and chronic obstructive pulmonary disease (1.81, 1.30 to 2.52). Participants with more respiratory symptoms and exposure to vapour, gas, dust and fumes (VGDF) (1.07 to 1.00-1.15), low-molecular weight (LMW) agents (1.19, 1.00 to 1.41) and irritating agents (1.15, 1.05 to 1.26) were more likely to be lost to follow-up. We found no statistically significant association of wheezing and exposure to LMW agents for all participants at baseline (1.11, 0.90 to 1.36), responders in 2018 (1.12, 0.83 to 1.53) and those lost to follow-up (1.07, 0.81 to 1.42).ConclusionThe risk factors for loss to 5-year follow-up were comparable to those reported in other population-based studies and included younger age, male gender, current smoking, lower educational level and higher symptom prevalence and morbidity. We found that exposure to VGDF, irritating and LMW agents can be risk factors associated with loss to follow-up. Results suggest that loss to follow-up did not affect estimates of occupational exposure as a risk factor for respiratory symptoms.
