- 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.

- 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 In the Nordic countries, recent pollution health impact assessments have had to rely on outdated studies.Aims: To investigate if air pollution exposure is associated with sick leave 20 years later.Methods: We analysed self-reported sick leave (all-cause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.

- 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.

- OBJECTIVES: To investigate the association of early snus use initiation (≤15 years of age) with asthma and asthma symptoms.DESIGN: Cross-sectional analysis of a population-based cohort.SETTING: Study centres in Norway, Sweden, Iceland, Denmark and Estonia, from 2016 to 2019.PARTICIPANTS: 9002 male and female participants above 15 years of age of the Respiratory Health in Northern Europe, Spain and Australia study.MAIN OUTCOME MEASURES: Current asthma and asthma symptoms.RESULTS: The median age of study participants was 28 years (range 15-53) and 58% were women. 20% had used snus, 29% men and 14% women. Overall, 26% of males and 14% of females using snus started ≤15 years of age. Early snus use initiation was associated with having three or more asthma symptoms (OR 2.70; 95% CI 1.46 to 5.00) and a higher asthma symptom score (β-coefficient (β) 0.35; 95% CI 0.07 to 0.63) in women. These associations were weak in men (OR 1.23; 95% CI 0.78 to 1.94; β 0.16; 95% CI -0.06 to 0.38, respectively). There was evidence for an association of early snus initiation with current asthma (OR 1.72; 95% CI 0.88 to 3.37 in women; OR 1.31; 95% CI 0.84 to 2.06 in men). A sensitivity analysis among participants without smoking history showed stronger estimates for all three outcomes, in both men and women, statistically significant for three or more asthma symptoms in women (OR 3.28; 95% CI 1.18 to 9.10). Finally, no consistent associations with asthma outcomes were found for starting snus after age 15 years.CONCLUSIONS: Snus initiation in puberty was associated with higher likelihood of asthma and asthma symptoms, with the highest estimates in females and those without smoking history. These results raise concerns about the health adversities of early snus initiation and emphasise the need for public health initiatives to protect young people from this tobacco product.

Tidskriftsartikel (refereegranskat)abstract
- Background: With increasing interest in exposure effects across generations, it is crucial to assess the validity of information given on behalf of others.Aims: To compare adult's report of their parent’s smoking status against parent's own report and examine predictors for discrepant answers.Methods: We studied 7185 offspring (18-51 years) and one of their parents, n = 5307 (27-67 years) participating in the Respiratory Health in Northern Europe, Spain and Australia (RHINESSA) generation study. Information about parent's smoking status during offspring's childhood and mother's smoking status during pregnancy was obtained by questionnaires from parents and their offspring. We calculated sensitivity, specificity and Cohen's Kappa [κ] for agreement using parent's own report as the gold standard. We performed logistic regression to examine if offspring's sex, age, educational level, asthma status, own smoking status or parental status, as well as the parent's sex and amount of smoking during childhood predicted disagreement.Results: The sensitivity for offspring's correct report of parent's smoking status during childhood (0-10 years) was 0.82 (95% CI 0.81–0.84), specificity was 0.95 (95% CI 0.95–0.96) and a good agreement was observed, κ = 0.79 (95% CI 0.78–0.80). Offspring's report of mothers' smoking status during pregnancy showed a lower sensitivity, 0.66 (95% CI 0.60–0.71), a slightly lower specificity, 0.92 (95% CI 0.90–0.95) and a good agreement, κ = 0.61 (95% CI 0.55–0.67). In multivariate logistic regression analysis, offspring not having children was a predictor for discrepant answers (odds ratio [OR] 2.11 [95% CI 1.21–3.69]). Low amount of parents' tobacco consumption, < 10 cigarettes/day (OR 2.72 [95% CI 1.71–4.31]) also predicted disagreement compared to ≥10 cigarettes per day, and so did offspring's reports of fathers' smoking status (OR 1.73 [95% CI 1.09–2.74]) compared to mothers' smoking status. Offspring's sex, asthma status, educational level, smoking status or age was not related to discrepant answers.Conclusions: Adults report their parent's smoking status during their childhood, as well as their mothers' smoking status when pregnant with them, quite accurately. In the absence of parents' direct report, offspring's reports could be valuable.

- Individuals raised on a farm appear to have less asthma than individual raised elsewhere. However, selective migration might contribute to this as may also the suggested protection from farm environment. This study investigated if parents with asthma are less likely to raise their children on a farm. This study involved three generations: 6045 participants in ECRHS/RHINE cohorts (born 1945-1973, denoted G1), their 10,121 parents (denoted G0) and their 8260 offspring participating in RHINESSA (born 1963-1998, denoted G2). G2-offspring provided information on parents not participating in ECRHS/RHINE. Asthma status and place of upbringing for all three generations were reported in questionnaires by G1 in 2010-2012 and by G2 in 2013-2016. Binary regressions with farm upbringing as outcome were performed to explore associations between parental asthma and offspring farm upbringing in G0-G1 and G1-G2. Having at least one parent with asthma was not associated with offspring farm upbringing, either in G1-G2 (RR 1.11, 95% CI 0.81-1.52) or in G0-G1 (RR 0.99, 0.85-1.15). G1 parents with asthma born in a city tended to move and raise their G2 offspring on a farm (RR 2.00, 1.12-3.55), while G1 parents with asthma born on a farm were less likely to raise their G2 offspring on a farm (RR 0.34, 0.11-1.06). This pattern was not observed in analyses of G0-G1. This study suggests that the protective effect from farm upbringing on subsequent asthma development could not be explained by selective migration. Intriguingly, asthmatic parents appeared to change environment when having children.

- Background: There is growing concern about health effects of cleaning agents. Emerging research suggests adverse health effects of exposures prior to conception.Aim: To study childhood asthma in relation to mother’s occupational exposure to indoor cleaning before conception and around pregnancy.Methods: The multi-centre two-generation RHINE/RHINESSA study investigated asthma and wheeze with onset <10 years in 3318 adults. Exposure of their mothers to indoor cleaning agents and disinfectants starting before conception, in the 2-year period around conception and pregnancy, or after birth, was defined from mothers’ occupational history in combination with an asthma-specific job exposure matrix. Examples of exposed groups are cleaners, cooks, and nurses. Ordinary and mixed effects logistic regression analyses accounted for family clustering and study centre, and adjusted for maternal education.Results: Mother’s exposure to indoor cleaning starting before conception and continuing (n=610;47%) was associated with offspring’s childhood asthma: adjusted Odds Ratio (OR)=1.6 (95%CI 1.1-2.3), childhood asthma with nasal allergies: 1.8 (1.1-2.8), and childhood wheeze: 2.0 (1.3-3.1). Exposure starting around the time of conception and pregnancy (n=77;6%) was associated with childhood asthma: 2.3 (1.0-5.3) and childhood asthma with nasal allergies: 2.5 (1.0-6.4).Conclusions: Maternal occupational exposure to indoor cleaning pre-conception, or around the time of conception and pregnancy, may be a risk factor for childhood asthma in offspring. Considering potential implications for women in childbearing age using cleaning agents, and their children, mechanistic research and replication in cohort studies are needed.
