- We estimated the association between regular physical activity and the incidence of restrictive spirometry pattern. Forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and physical activity were assessed in 2 population-based European cohorts (European Community Respiratory Health Survey: n = 2,757, aged 39–67 years; and Swiss Study on Air Pollution and Lung and Heart Diseases in Adults: n = 2,610, aged 36–82 years) first in 2000–2002 and again approximately 10 years later (2010–2013). Subjects with restrictive or obstructive spirometry pattern at baseline were excluded. We assessed the association of being active at baseline (defined as being physically active at least 2–3 times/week for ≥1 hour) with restrictive spirometry pattern at follow-up (defined as a postbronchodilation FEV1/FVC ratio of at least the lower limit of normal and FVC of <80% predicted) using modified Poisson regression, adjusting for relevant confounders. After 10 years of follow-up, 3.3% of participants had developed restrictive spirometry pattern. Being physically active was associated with a lower risk of developing this phenotype (relative risk = 0.76, 95% confidence interval: 0.59, 0.98). This association was stronger among those who were overweight and obese than among those of normal weight (P for interaction = 0.06). In 2 large European studies, adults practicing regular physical activity were at lower risk of developing restrictive spirometry pattern over 10 years.

- Introduction: Restrictive spirometry pattern is an under-recognised disorder with a poor morbidity and mortality prognosis. We compared physical activity levels between adults with a restrictive spirometry pattern and with normal spirometry.Methods: Restrictive spirometry pattern was defined as a having post-bronchodilator FEV1/FVC ≥ Lower Limit of Normal and a FVC<80% predicted in two population-based studies (ECRHS-III and SAPALDIA3). Physical activity was measured using the International Physical Activity Questionnaire. The odds of having low physical activity (<1st study-specific tertile) was evaluated using adjusted logistic regression models.Results: Subjects with a restrictive spirometry pattern (n = 280/4721 in ECRHS, n = 143/3570 in SAPALDIA) reported lower levels of physical activity than those with normal spirometry (median of 1770 vs 2253 MET·min/week in ECRHS, and 3519 vs 3945 MET·min/week in SAPALDIA). Subjects with a restrictive spirometry pattern were more likely to report low physical activity (meta-analysis odds ratio: 1.41 [95%CI 1.07–1.86]) than those with a normal spirometry. Obesity, respiratory symptoms, co-morbidities and previous physical activity levels did not fully explain this finding.Conclusion: Adults with a restrictive spirometry pattern were more likely to report low levels of physical activity than those with normal spirometry. These results highlight the need to identify and act on this understudied but prevalent condition.

- Background Understanding the natural history of abnormal spirometric patterns at different stages of life is critical to identify and optimise preventive strategies. We aimed to describe characteristics and risk factors of restrictive and obstructive spirometric patterns occurring before 40 years (young onset) and between 40 and 61 years (mid-adult onset). Methods We used data from the population- based cohort of the European Community Respiratory Health Survey (ECRHS). Prebronchodilator forced expiratory volume in one second (FEV 1) and forced vital capacity (FVC) were assessed longitudinally at baseline (ECRHS1, 1993-1994) and again 20 years later ( ECRHS3, 2010-2013). Spirometry patterns were defined as: restrictive if FEV1/ FVC >= LLN and FVC<10th percentile, obstructive if FEV1/FVC

- Objective: The aim of the present study was to validate figural drawing scales depicting extremely lean to extremely obese subjects to obtain proxies for BMI and waist circumference in postal surveys.Design: Reported figural scales and anthropometric data from a large population-based postal survey were validated with measured anthropometric data from the same individuals by means of receiver-operating characteristic curves and a BMI prediction model.Setting: Adult participants in a Scandinavian cohort study first recruited in 1990 and followed up twice since.Subjects: Individuals aged 38-66 years with complete data for BMI (n 1580) and waist circumference (n 1017).Results: Median BMI and waist circumference increased exponentially with increasing figural scales. Receiver-operating characteristic curve analyses showed a high predictive ability to identify individuals with BMI > 25.0 kg/m(2) in both sexes. The optimal figural scales for identifying overweight or obese individuals with a correct detection rate were 4 and 5 in women, and 5 and 6 in men, respectively. The prediction model explained 74% of the variance among women and 62% among men. Predicted BMI differed only marginally from objectively measured BMI.Conclusions: Figural drawing scales explained a large part of the anthropometric variance in this population and showed a high predictive ability for identifying overweight/obese subjects. These figural scales can be used with confidence as proxies of BMI and waist circumference in settings where objective measures are not feasible.

- Objective: To determine whether early life factors associated with poor lung growth and submaximal attained lung function contribute to accelerated lung function decline later in life.Methods: Participants in the European Community Respiratory Health Survey (ECRHS) and the Northern Finland Birth Cohort 1966 (NFBC1966) with lung function measured in a first (n=10,971), second (n=7,981) and third wave (n=4,849), aged 20 – 68 years, were included. Mean annual decline in maximum forced expired volume in 1 second (FEV1) and forced vital capacity (FVC) were main outcomes. Information on early life factors was provided by standardized interviews and questionnaires. We estimated the effect of early life factors including maternal age, parental smoking, season of birth, parental asthma and respiratory infections using mixed effects models, adjusted for age, FEV1 and FVC at baseline, height, and smoking habits.Results: Decline in FEV1 was accelerated in women born of a mother with asthma (β = 2.4 ml; 95% CI 0.6-4.3) or who smoked during pregnancy (1.9; 0.2-3.6), and in men having a father with asthma (3.5; 0.2-6.9) or born by Cesarean section (7.9; 1.6-14.2). Accelerated decline in FVC was associated with paternal asthma in men (4.3; 0.1-8.5) and early menarche (<12 years) in women (2.4; 0.4-4.4). No statistically significant effect on lung function decline was found for other investigated early life factors.Conclusion: Early life risk factors contribute to an accelerated lung function decline with ageing, following sex-specific patterns. Decline in FEV1 versus FVC showed slightly different patterns.

- 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.

- There is limited information about potential impact of maternal age on the respiratory health of offspring. We investigated the association of maternal age at delivery with adult offspring's lung function, respiratory symptoms and asthma, and potential differences according to offspring sex. 10 692 adults from 13 countries participating in the European Community Respiratory Health Survey (ECRHS) II responded to standardised interviews and provided lung function measurements and serum for IgE measurements at age 25-55 years. In logistic and linear multilevel mixed models we adjusted for participants' characteristics (age, education, centre, number of older siblings) and maternal characteristics (smoking in pregnancy, education) while investigating for differential effects by sex. Maternal age was validated in a subsample using data from the Norwegian birth registry. Increasing maternal age was associated with increasing forced expiratory volume in 1 s (2.33 mL per year, 95% CI 0.34-4.32 mL per year), more consistent in females (p(trend) 0.025) than in males (ptrend 0.14). Asthma (OR 0.85, 95% CI 0.79-0.92) and respiratory symptoms (OR 0.87, 95% CI 0.82-0.92) decreased with increasing maternal age (per 5 years) in females, but not in males (p(interaction) 0.05 and 0.001, respectively). The results were consistent across centres and not explained by confounding factors. Maternal ageing was related to higher adult lung function and less asthma/symptoms in females. Biological characteristics in offspring related to maternal ageing are plausible and need further investigation.

- Objectives: Menopause involves hypoestrogenism, which is associated with numerous detrimental effects, including on respiratory health. Hormone replacement therapy (HRT) is often used to improve symptoms of menopause. The effects of HRT on lung function decline, hence lung ageing, have not yet been investigated despite the recognized effects of HRT on other health outcomes. Study design: The population-based multi-centre European Community Respiratory Health Survey provided complete data for 275 oral HRT users at two time points, who were matched with 383 nonusers and analysed with a two-level linear mixed effects regression model. Main outcome measures: We studied whether HRT use was associated with the annual decline in forced vital capacity (FVC) and forced expiratory volume in one second (FEV1). Results: Lung function of women using oral HRT for more than five years declined less rapidly than that of nonusers. The adjusted difference in FVC decline was 5.6 mL/y (95%CI: 1.8 to 9.3, p = 0.01) for women who had taken HRT for six to ten years and 8.9 mL/y (3.5 to 14.2, p = 0.003) for those who had taken it for more than ten years. The adjusted difference in FEV1 decline was 4.4 mL/y (0.9 to 8.0, p = 0.02) with treatment from six to ten years and 5.3 mL/y (0.4 to 10.2, p = 0.048) with treatment for over ten years. Conclusions: In this longitudinal population-based study, the decline in lung function was less rapid in women who used HRT, following a dose-response pattern, and consistent when adjusting for potential confounding factors. This may signify that female sex hormones are of importance for lung ageing.
