Objectives: Studies have shown that declining participation in epidemiological studies may lead to biased estimates of occurrence and selection bias. Nevertheless, studies on non-participation and loss to follow-up in prospective studies are rare. Aim: The aim of the study was to characterize those lost to follow-up and possible factors associated with non-participation in a prospective population based study of respiratory health in Norway. Methods: A five-year follow-up of the population based sample (n=16 099), aged 21-55 years, from the Telemark study was conducted in 2018. Risk factors associated with loss to follow-up were assessed by forward conditional logistic regression. Results: A total of 8 244 (51.2%) participants were lost to follow-up. Non-participation was associated with male sex, younger age, low education, current smoking, unemployment, reduced workability, asthma, being woken by chest tightness and COPD. Conclusion: The risk factors for participants lost to five-year follow-up are comparable to those reported in population-based studies for non-responders, mainly related to younger age, male gender, current smoking, low socioeconomic status, and higher symptom prevalence and morbidity.

Background: Fractional exhaled nitric oxide (FENO) is increasingly used in asthma, but its role in occupational asthma (OA) is not established. Aim: To explore relationships between FENO and symptoms, asthma, and lung function in wood, foundry, and laboratory animal workers. Method: Workers underwent validated questionnaire, FENO, and spirometry measured to ATS/ERS standards. Associations were examined between FENO >40ppb and work-related respiratory symptoms (WRRS); and between current asthma symptoms (CAS) and either FENO >40ppb, or CAS and FEV1 below the lower limit of normal (LLN). Degree of overlap between workers with FENO >40ppb, FEV1 Results: In total 655 workers took part. Mean age was 39 (SD 12.5) years, 86% were male and 25% current smokers. Overall 40% of workers reported CAS and 20% had elevated FENO. FENO >40ppb was associated with asthma (OR for FENO >40 ppb 2.12, 95% CI 1.19 – 3.78). Nine per cent of workers had both CAS and high FENO: the risk of WRRS was elevated in this group (OR 3.75, 2.01 – 7.00). No increased risk of WRRS was seen in workers with CAS and obstructive spirometry. Among workers with CAS, little overlap existed between those with high FENO and those with low FEV1. Over half those with CAS and high FENO had no previous asthma diagnosis. Conclusion: CAS were common among workers exposed to a range of known occupational allergens. Measurement of FENO in the workplace can be used to help identify symptomatic workers with eosinophilic airway inflammation. A significant proportion of these workers have never been diagnosed with asthma, suggesting there may be a role for FENO in health surveillance for OA.
