- AIM: Heritability of cough has not yet been studied. We aimed to evaluate if individuals with cough are more likely to have offspring who develop cough, and if these associations differ by type of cough (productive/nonproductive).METHODS: The RHINESSA Generation Study (Respiratory Health In Northern Europe, Spain and Australia) includes 7155 parents (initially aged 30-54) answering detailed questionnaires in 2000 and 2010, and 8176 offspring ≥20 years answering similar questionnaires in 2012-2019. Chronic cough was categorised as productive or nonproductive (dry) cough. Associations between parental and offspring cough were analysed using mixed-effects logistic regression, adjusting for offspring age, sex, body mass index, smoking history, education level, current asthma, rhinitis, nocturnal gastroesophageal reflux; parent sex and smoking history; centre and family.RESULTS: Among parents with nonproductive cough, 11% of their offspring reported nonproductive cough, compared with 7% of offspring to parents without nonproductive cough, adjusted odds ratio (aOR) 1.59 (95% confidence interval 1.20-2.10). Among parents with productive cough, 14% of their offspring reported productive cough, compared with 11% of offspring to parents without productive cough, aOR 1.34 (1.07-1.67). No associations were found between parent productive cough-offspring nonproductive cough, nor between parent nonproductive cough-offspring productive cough.CONCLUSIONS: Parents with chronic cough are more likely to have offspring with chronic cough independent of parental asthma, suggesting cough to be a separate heritable trait. The type of cough is important, as the nonproductive cough in parent associates only with nonproductive cough in offspring, and the same applied for productive cough.

- Background: Although asthma and allergic rhinitis are chronic diseases, some patients experience periods of remission. Information on prognostic factors associated with the remission of asthma and allergic rhinitis is valuable in resource prioritization. This study investigated factors associated with the clinical remission of asthma and allergic rhinitis.Methods: In the Respiratory Health In Northern Europe (RHINE) study, data was collected with questionnaires in stage one (RHINE I, 1989–1992) and two follow-ups (RHINE II, 1999–2001 and RHINE III, 2010–2012) from Sweden, Norway, Denmark, Iceland and Estonia. Clinical remission was defined as having reported asthma or allergic rhinitis in RHINE I or RHINE II but not in RHINE III.Results: Of 13,052 participants, 975 (7.5%) reported asthma in RHINE I or RHINE II, and 3379 (25.9%) allergic rhinitis. Clinical remission of asthma and allergic rhinitis was found in 46.4% and 31.8%, respectively. Living in Estonia (OR (95% CI) 2.44 (1.22– 4.85)) and living in an apartment (1.45 (1.06–1.98)) were related to remission of asthma, while subjects reporting allergic rhinitis (0.68 (0.51–0.90)), asthma onset ≤ 12 years of age (0.49 (0.35–0.68)), receiving treatment with antibiotics for respiratory illness (0.64 (0.47– 0.87)) were less likely to have asthma remission. Factors related to a higher likelihood of remission of allergic rhinitis were no asthma at baseline, age ≥ 58 years in RHINE III, allergic rhinitis onset after 12 years of age, living in rural areas as a child, having only a primary school education and not being pregnant.Conclusion: Clinical remission was found in almost one-half of those with asthma and one-third of persons with allergic rhinitis. Coexisting allergic symptoms were associated with less clinical asthma remission. Age, asthma symptoms and environmental factors in childhood, such as living in a rural area, were found to influence the clinical remission of allergic rhinitis.

- Background: The aim of this investigation was to study change in adults over a 20 year period in the prevalence of respiratory symptoms and disorders and its association to year of birth, life style and sleep related variables.Method: Adults 20-44 years of age, 6085 women and 5184 men, were randomly selected from seven centres in Northern Europe and followed for 20 years. The number of participants in the first survey was 21,595 and 11,269 participated in all three surveys. The participants were divided into three birth cohorts: 1944-1955, 1956-1965 and 1966-1975.Results: During the 20 year period the prevalence of wheeze decreased (-2%) and the prevalence of asthma (+ 4%) and allergic rhinitis (+ 5%) increased, whereas the prevalence of nocturnal respiratory symptoms was relatively unchanged. The increase in allergic rhinitis was largest in those born 1966 to 1975 except in Estonia. There was large decrease in smoking (-20%), increase in obesity (+ 7%) and snoring (+ 6%) during the study period. Smoking, obesity, snoring and nocturnal gastroesophageal reflux (nGER) were related to a higher risk of all symptoms. Obesity, snoring and nGER were also independently related to asthma.Conclusion: We conclude that as our participants got older there was a decrease in wheeze, no change in nocturnal symptoms and an increase in reported asthma and allergic rhinitis. These changes in prevalence are probably related to a decrease in smoking being counteracted by an increase in allergy, obesity and sleep related disorders.

- Study objectives: To analyze the association between sleep-related symptoms and sleep length in parents and their children in relation to other risk factors in both generations. Method: The participants were parents (n = 5,855, age 54.3 +/- 6.5 years, 45.2% men) who participated in the community-based Respiratory Health in Northern Europe (RHINE) study and one random member of their adult offspring (n = 5,855, age 30.2 +/- 7.7 years, 41.5% men) who participated in the Respiratory Health in Northern Europe, Spain and Australia (RHINESSA) study. Both generations responded to identical questionnaires on sleep symptoms, including difficulty initiating sleep (DIS), difficulty maintaining sleep (DMS), early morning awakening (EMA), snoring, nocturnal sweating, nocturnal gastroesophageal reflux (nGER), sleep time and excessive daytime sleepiness (EDS). Insomnia was defined as either, or both, DIS and DMS in combination with EDS. Results: All sleep variables except nocturnal sweating were more common in offspring whose parents had reported the same symptom. After adjusting for age, gender, BMI, smoking, physical activity, education, center and parents' total number of children, there were independent associations between sleep symptoms in parents and offspring for DIS (adj. OR, 95% CI: 1.52, 1.20-1.93), DMS (1.34, 1.15-1.56), snoring (1.45, 1.15,1.83), nGER (1.65, 1.15-2.37), insomnia (1.39, 1.13-1.73), short sleep time (<6 h/night) (2.51, 1.72-3.68) and EDS (1.48, 1.26,1.72). There were no independent relationships between symptoms in parents and offspring for EMA, nocturnal sweating or long sleep time (>9 h/night). Conclusion: The familiar aggregation of many sleep disturbances was not explained by investigated lifestyle and environmental factors. This supports a heritable factor in sleep problems.

- Background: We found that a father’s overweight in puberty was associated with non-allergic asthma in his future offspring.Aim: We explored the associations of both fathers and their offsprings own weight gain throughout the lifespan with offspring non-allergic asthma.Methods: We analysed questionnaire data from 3018 adult offspring (age 18-50) and their 2153 fathers (age 39-66) participating in the RHINESSA/RHINE generation study in 10 ECRHS centres in North Europe, Spain and Australia. The associations of fathers' and their offsprings weight gain was assessed by 9 body silhouettes (from lean to fat) self-reported for childhood, puberty and adult ages with non-allergic asthma in the offspring. It was analysed using a logistic regression model adjusted for parents and offspring variables, and cluster by family.Results: Non-allergic asthma was related to a weight gain of ≥2 body silhouettes from 8 years to puberty, both for fathers’ weight gain (OR 1.69; 95% CI 1.05-2.72; adjusted for fathers asthma, offspring body mass index, smoking and education) and for their offspring weight gain (1.77 [1.12-2.79], adjusted for parents´ education, smoking and asthma, and fathers´ weight gain from age 8 to puberty). If the father was overweight at puberty, in addition to having gained weight, non-allergic asthma in the offspring was more than tripled (3.53[1.80-6.94]; weight gain and adjustment as given above). No effect of weight gain from puberty or within adulthood in fathers’ or their offspring was observed.Conclusion: Non-allergic asthma was associated with weight gain from childhood to puberty. This was found both for personal weight gain and for having a father who gained weight.

- 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.
