- Background: Self-report questionnaires are commonly used in epidemiology, but may be susceptible to misclassification, especially if answers are given on behalf of others, e.g. children or parents. The aim was to determine agreement and analyse predictors of disagreement in parents' reports of offspring asthma, and in offspring reports of parents' asthma. Methods: In the Respiratory Health in Northern Europe, Spain and Australia (RHINESSA) generation study, 6752 offspring (age range 18-51 years) and their parents (age range 39-66 years) reported their own and each other's asthma status. Agreement between asthma reports from offspring and parents was determined by calculating sensitivity, specificity, positive and negative predictive value and Cohen's kappa. The participants' own answers regarding themselves were defined as the gold standard. To investigate predictors for disagreement logistic regression analyses were performed to obtain odds ratios (OR) with 95% confidence intervals (CI) for sex, smoking status, education, comorbidity and severity of asthma. Results: Agreement was good for parental report of offspring early onset asthma (< 10 years, Cohen's kappa 0.72) and moderate for offspring later onset asthma (Cohen's kappa 0.46). Specificity was 0.99 for both, and sensitivity was 0.68 and 0.36, respectively. For offspring report of maternal and paternal asthma the agreement was good (Cohen's kappa 0.69 and 0.68), specificity was 0.96 and 0.97, and sensitivity was 0.72 and 0.68, respectively. The positive predictive value (PPV) was lowest for offspring report of maternal asthma (0.75), and highest for parents' report of early onset asthma in the offspring (0.83). The negative predictive value (NPV) was high for all four groups (0.94-0.97). In multivariate analyses current smokers (OR = 1.46 [95% CI 1.05, 2.02]) and fathers (OR = 1.31 [95% CI 1. 08, 1.59]) were more likely to report offspring asthma incorrectly. Offspring wheeze was associated with reporting parental asthma incorrectly (OR = 1.60 [95% CI 1.21, 2.11]), both under- and over reporting. Conclusions: Asthma reports across generations show moderate to good agreement, making information from other generations a useful tool in the absence of direct reports.

- Background: Little is known on childhood exposure to air pollution and adult chronic respiratory outcomes.Aim: To investigate associations between air pollution and greenness in childhood and adult lung health.Methods: In selected centres of the RHINESSA study (age 18-52) we analysed the outcomes respiratory symptoms (≥3 symptoms), severe wheeze (wheeze last year with breathlessness, no cold) and late onset asthma (>10 years). We calculated mean annual exposures of PM2.5, PM10, NO2 (µg/m³) and greenness (Normalized Difference Vegetation Index, 100m buffer) from offspring's birth till age 18, categorised into mean exposure <10 years and 11-18 years. We performed multilevel logistic regression clustered by family, stratified by centre and adjusted for childhood passive smoke and parental asthma.Results: 12% had ≥3 respiratory symptoms, 7.7% severe wheeze, and 9.4% late onset asthma. Overall estimates: greenness was associated with less respiratory symptoms, PM2.5 and NO2 with more late onset asthma. Exposure <10 years: Greenness was associated with less wheeze in Tartu (OR 0.29, 95%CI 0.11-0.73). PM2.5 (OR 1.22, 95%CI 1.00-1.48) and NO2 (OR 1.06, 95%CI 1.01-1.11) were risk factors for late onset asthma in Bergen. PM10 was a risk factor for respiratory symptoms (OR 1.21, 95%CI 1.04-1.41) in Uppsala and late onset asthma (OR 1.23, 95%CI 1.02-1.45) in Bergen. Exposure 11-18 years: Greenness was protective for respiratory symptoms (OR 0.29, 95%CI 0.10-0.86) and wheeze (OR 0.39, 95%CI 0.19-0.80) in Tartu.Conclusions: Childhood exposure to greenness was associated with less respiratory symptoms, while air pollutants were associated with more respiratory symptoms (some centres) and late onset asthma.

- Background: Women are often underrepresented at sleep clinics evaluating sleep-disordered breathing (SDB). The aim of the present study was to analyze gender differences in sleep apnea diagnosis and treatment in men and women with similar symptoms of SDB.Methods: Respiratory Health in Northern Europe (RHINE) provided information about snoring, excessive daytime sleepiness (EDS), BMI and somatic diseases at baseline (1999-2001) and follow-up (2010-2012) from 4962 men and 5892 women. At follow-up participants were asked whether they had a diagnosis of and/or treatment for sleep apnea.Results: Among those with symptoms of SDB (snoring and EDS), more men than women had been given the diagnosis of sleep apnea (25% vs. 14%, p < 0.001), any treatment (17% vs. 11%, p = 0.05) and CPAP (6% vs. 3%, p = 0.04) at follow-up. Predictors of receiving treatment were age, BMI, SDB symptoms at baseline and weight gain, while female gender was related to a lower probability of receiving treatment (adj OR 0.3, 95% CI 0.3-0.5). In both genders, the symptoms of SDB increased the risk of developing hypertension (adj OR, 95% CI: 1.5, 1.2-1.8); and diabetes (1.5, 1.05-2.3), independent of age, BMI, smoking and weight gain.Conclusions: Snoring females with daytime sleepiness may be under-diagnosed and under-treated for sleep apnea compared with males, despite running a similar risk of developing hypertension and diabetes.

- 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.

- Life course data on obesity may enrich the quality of epidemiologic studies analysing health consequences of obesity. However, achieving such data may require substantial resources. We investigated the use of body silhouettes in adults as a tool to reflect obesity in the past. We used large population-based samples to analyse to what extent self-reported body silhouettes correlated with the previously measured (9-23 years) body mass index (BMI) from both measured (European Community Respiratory Health Survey, N = 3 041) and selfreported (Respiratory Health In Northern Europe study, N = 3 410) height and weight. We calculated Spearman correlation between BMI and body silhouettes and ROC-curve analyses for identifying obesity (BMI >= 30) at ages 30 and 45 years. Spearman correlations between measured BMI age 30 (+/- 2y) or 45 (+/- 2y) and body silhouettes in women and men were between 0.62-0.66 and correlations for self-reported BMI were between 0.58-0.70. The area under the curve for identification of obesity at age 30 using body silhouettes vs previously measured BMI at age 30 (+/- 2y) was 0.92 (95% CI 0.87, 0.97) and 0.85 (95% CI 0.75, 0.95) in women and men, respectively; for previously self-reported BMI, 0.92 (95% CI 0.88, 0.95) and 0.90 (95% CI 0.85, 0.96). Our study suggests that body silhouettes are a useful epidemiological tool, enabling retrospective differentiation of obesity and non-obesity in adult women and men.

- Background Tobacco consumption is the largest avoidable health risk. Understanding changes of smoking over time and across populations is crucial to implementing health policies. We evaluated trends in smoking initiation between 1970 and 2009 in random samples of European populations. We pooled data from six multicentre studies involved in the Ageing Lungs in European Cohorts consortium, including overall 119,104 subjects from 17 countries (range of median ages across studies: 33-52 years). We estimated retrospectively trends in the rates of smoking initiation (uptake of regular smoking) by age group, and tested birth cohort effects using Age-Period-Cohort (APC) modelling. We stratified all analyses by sex and region (North, East, South, West Europe). Smoking initiation during late adolescence (16-20 years) declined for both sexes and in all regions (except for South Europe, where decline levelled off after 1990). By the late 2000s, rates of initiation during late adolescence were still high (40-80 per 1000/year) in East, South, and West Europe compared to North Europe (20 per 1000/year). Smoking initiation rates during early adolescence (11-15 years) showed a marked increase after 1990 in all regions (except for North European males) but especially in West Europe, where they reached 40 per 1000/year around 2005. APC models supported birth cohort effects in the youngest cohorts. Smoking initiation is still unacceptably high among European adolescents, and increasing rates among those aged 15 or less deserve attention. Reducing initiation in adolescents is fundamental, since youngsters are particularly vulnerable to nicotine addiction and tobacco adverse effects.

Tidskriftsartikel (refereegranskat)abstract
- Background The term Asthma and COPD Overlap (ACO) describes a condition where asthma and COPD overlap. We aimed to investigate associations between ACO and insomnia and respiratory symptoms, and to investigate the prevalence of ACO and the characteristics of subjects with ACO in two Northern European population studies. The study comprised 25 429 subjects aged >40 years who participated in one of two Northern European general population surveys. Both surveys included questions on asthma, COPD, respiratory and sleep-related symptoms, including difficulty initiating sleep, difficulty maintaining sleep, early-morning awakening, and excessive daytime sleepiness. ACO was defined as having both self-reported asthma and COPD. The prevalence of ACO was 1.0%. The group with ACO had a higher prevalence of both insomnia and respiratory symptoms than subjects with only asthma or COPD. Having ACO was independently associated with a 2-3 times higher probability of having sleep-related symptoms as compared with the group without asthma or COPD, after adjustment for age, sex, BMI, smoking history and educational level (adjusted odds ratio 2.14-3.36, 95% CI). Subjects with ACO have a high prevalence of insomnia and respiratory symptoms. To our knowledge, this is the first study to assess the association between sleep-related symptoms and ACO.

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.
