- AIMS: We investigate (a) alcohol consumption in association with type 2 diabetes, taking heavy episodic drinking (HED), socioeconomic, health and lifestyle, and psychosocial factors into account, and (b) whether a seemingly protective effect of moderate alcohol consumption on type 2 diabetes persists when stratified by occupational position.METHODS: This population-based longitudinal cohort study comprises 16,223 Swedes aged 18-84 years who answered questionnaires about lifestyle, including alcohol consumption in 2002, and who were followed-up for self-reported or register-based diabetes in 2003-2011. Odds ratios (ORs) with 95% confidence intervals (CIs) were estimated in a multivariable-adjusted logistic regression model for all participants and stratified by high and low occupational position. We adjusted for HED, socioeconomic (occupational position, cohabiting status and unemployment), health and lifestyle (body mass index (BMI), blood pressure, smoking, physical inactivity, poor general health, anxiety/depression and psychosocial (low job control and poor social support) characteristics one by one, and the sets of these factors.RESULTS: Moderate consumption was inversely associated with type 2 diabetes after controlling for health and lifestyle (OR=0.47; 95% CI: 0.29-0.79) and psychosocial factors (OR=0.40; 95% CI: 0.22-0.79) when compared to non-drinkers. When adjusting for socioeconomic factors, there was still an inverse but non-significant association (OR=0.59; 95% CI: 0.35-1.00). In those with high occupational position, there was no significant association between moderate consumption and type 2 diabetes after adjusting for socioeconomic (OR=0.67; 95% CI: 0.3-1.52), health and lifestyle (OR=0.70; 95% CI: 0.32-1.5), and psychosocial factors (OR=0.75; 95% CI: 0.23-2.46). On the contrary, in those with low occupational position, ORs decreased from 0.55 (95% CI: 0.28-1.1) to 0.35 (95% CI: 0.15-0.82) when adjusting for psychosocial factors, a decrease that was solely due to low job control. HED did not influence any of these associations.CONCLUSIONS: Moderate alcohol consumption is associated with a lower risk of type 2 diabetes, after adjusting for HED, health and lifestyle, and psychosocial characteristics. The association was inverse but non-significant after adjusting for socioeconomic factors. When stratified by occupational position, there was an inverse association only in those with low occupational position and after adjusting for low job control.

- Objective: The aim of this study was to examine the associations between psychosocial factors and family background and incidence of anorexia nervosa (AN) in a Swedish cohort. Method: The Stockholm Birth Cohort, SBC (N = 14,294) contains information on social background and general health in males and females, born in Stockholm 1953. Hospitalizations for AN, based on diagnoses from the ICD-8 through ICD-10, were recorded from 1969 to 2002. Cox proportional hazard regression was used to measure the association between psychosocial characteristics and family background and the risk of AN. Results: Higher maternal education was associated with a higher risk for hospitalization for AN. An increased risk for AN was also found among females who stated that they “often compare their future prospects with others.” Discussion: Although the study is based on a low number of cases, it confirms earlier findings of higher maternal education among individuals with eating disorders in similar cohorts.

- Introduction: Eating disorders (ED) are among the leading causes of disease burden, especially in women.Objectives: The overall aim is to explore role of parental social characteristics and family composition in the development of ED in adolescent males and females.Aims: We investigated associations of parental socioeconomic position, family type, number of siblings and half-siblings and history of psychiatric disease in parents with the incidence of eating disorders at age 12–23 years.Methods: The Stockholm Youth Cohort (N = 589,114) is a database created by record-linkage for all children and adolescents, 0–17 years, resident in Stockholm County during the period 2001–2007, their parents and siblings. Hazard rations were calculated using Cox regression. Cases of ED were identified in outpatient care.Results: A total of 3251 cases of ED (2971 females and 280 males) were recorded among 249,884 study subjects. There was an increased risk of ED in both male and female offspring of parents who had a history of alcohol and drug abuse or psychiatric ill-health. Higher parental education was a risk factors in females. Increasing number of full siblings had a protective effect (fully adjusted HR 0.91, 95% CI 0.87–0.96, per sibling) while increasing number of half-siblings appeared to increase risk of eating disorders in females.Conclusions: Risk factors for ED seem to differ between females and males. While parental psychiatric health is related to risk of ED in both sexes, family socioeconomic position and relationships within family appear to be of more importance for influencing risk of ED in females.

- Objective: We examined how parental characteristics and other aspects of family background were associated with the development of eating disorders (ED) in males and females.Method: We used register data and record linkage to create the prospective, total-population study the Stockholm Youth Cohort. This cohort comprises all children and adolescents who were ever residents in Stockholm County between 2001 and 2007, plus their parents and siblings. Individuals born between 1984 and 1995 (N = 249, 884) were followed up for ED from age 12 to end of 2007. We used Cox regression modeling to investigate how ED incidence was associated with family socioeconomic position, parental age, and family composition.Results: In total, 3,251 cases of ED (2,971 females; 280 males) were recorded. Higher parental education independently predicted a higher rate of ED in females [e.g., adjusted hazard ratio (HR) 1.69 (95% CI: 1.42, 2.02) for degree-level vs. elementary-level maternal education], but not in males [HR 0.73 (95% CI: 0.42, 1.28), p < 0.001 for gender interaction]. In females, an increasing number of full-siblings was associated with lower rate of ED [e.g., fully adjusted HR 0.92 (95% CI: 0.88, 0.97) per sibling], whereas an increasing number of half-siblings was associated with a higher rate [HR 1.05 (95% CI: 1.01, 1.09) per sibling].Discussion: The effect of parental education on ED rate varies between males and females, whereas the effect of number of siblings varies according to whether they are full or half-siblings. A deeper understanding of these associations and their underlying mechanisms may provide etiological insights and inform the design of preventive interventions

- Eating disorders are a leading cause of disease burden amongyoung women. This study investigated associations of socialcharacteristics of parents and grandparents, sibling position,and school performance with incidence of eating disorders. Theauthors studied Swedish females born in 1952–1989 (n =13,376), third-generation descendants of a cohort born in Uppsalain 1915–1929. Data on grandparental and parental socialcharacteristics, sibling position, school grades, hospitalizations,emigrations, and deaths were obtained by register linkages.Associations with incidence of hospitalization for eating disorderswere studied with multivariable Cox regression, adjusted forage and study period. Overall incidence of hospitalization foreating disorders was 32.0/100,000 person-years. Women with morehighly educated parents and maternal grandparents were at higherrisk (hazard ratio for maternal grandmother with higher educationrelative to elementary education = 6.5, 95% confidence interval:2.2, 19.3, adjusted for parental education). Independent offamily social characteristics, women with the highest schoolgrades had a higher risk of eating disorders (hazard ratio =7.7, 95% confidence interval: 2.5, 24.1 for high compared withlow grades in Swedish, adjusted for parental education). Thus,higher parental and grandparental education and higher schoolgrades may increase risk of hospitalization for eating disordersin female offspring, possibly because of high internal and externaldemands.

- The ATHLOS cohort is composed of several harmonized datasets of international groups related to health and aging. As a result, the Healthy Aging index has been constructed based on a selection of variables from 16 individual studies. In this paper, we consider additional variables found in ATHLOS and investigate their utilization for predicting the Healthy Aging index. For this purpose, motivated by the volume and diversity of the dataset, we focus our attention upon data clustering, where unsupervised learning is utilized to enhance prediction power. Thus we show the predictive utility of exploiting hidden data structures. In addition, we demonstrate that imposed computation bottlenecks can be surpassed when using appropriate hierarchical clustering, within a clustering for ensemble classification scheme, while retaining prediction benefits. We propose a complete methodology that is evaluated against baseline methods and the original concept. The results are very encouraging suggesting further developments in this direction along with applications in tasks with similar characteristics. A straightforward open source implementation for the R project is also provided (https://github.com/Petros-Barmpas/HCEP).

- Longevity risk means living longer than predicted. Attempts to understand longevity risk to date have concentrated on single diseases, usually coronary heart disease, and sought explanations in terms of risk factor change and medical innovation. In an opening paper, David Blane and colleagues point to evidence that suggests changes in positive health also should be considered; and that a life course approach can do so in a way that is socially and biologically plausible. Applying this approach to UK citizens currently aged 85 years suggests that life course research should give priority to trajectories across the whole life course and to the social and material contexts through which each cohort has passed. Testing these ideas will require inter-disciplinary and international comparative research. The opening paper is followed by commentaries from Hans-Werner Wahl, Mark Hayward, Aart Liefbroer and Gita Mishra. Finally Blane and colleagues respond to the points raised by the commentators.

- OBJECTIVE: To investigate which parental mental illnesses are associated with eating disorders in their offspring.METHOD: We used data from a record-linkage cohort study of 158,679 children aged 12-24 years at the end of follow-up, resident in Stockholm County from 2001 to 2007, to investigate whether different parental mental illnesses are risk factors for eating disorders in their offspring. The outcome measure was diagnosis of any eating disorder, either from an ICD or DSM-IV code, or inferred from an appointment at a specialist eating disorder clinic.RESULTS: Mental illness in parents is a risk factor for eating disorders in female offspring (Adjusted Hazard Ratio (AHR) 1.57 (95% CI 1.42, 1.92), p < 0.0001). Risk of eating disorders is increased if there is a parental diagnosis of bipolar affective disorder (AHR 2.28 (95% CI 1.39, 3.72), p = 0.004), personality disorder (AHR 1.57 (95% CI 1.01, 2.44), p = 0.043) or anxiety/depression (AHR 1.57 (95% CI 1.32, 1.86), p < 0.0001). There is a lack of statistical evidence for an association with parental schizophrenia (AHR 1.41 (95% CI 0.96, 2.07), p = 0.08), and somatoform disorder (AHR 1.25 (95% CI 0.74, 2.13), p = 0.40). There is no support for a relationship between parental substance misuse and eating disorders in children (AHR 1.08 (95% CI 0.82, 1.43), p = 0.57).DISCUSSION: Parental mental illness, specifically parental anxiety, depression, bipolar affective disorder, and personality disorders, are risk factors for eating disorders in their offspring.

- METHODS: A total of 22 centres entered the study. The catchment areas of these centres covered cities and towns with more than 20 000 inhabitants, smaller towns (<= 20 000 inhabitants) with surrounding villages and rural areas, and were spread over the whole country, corresponding well to the geographical distribution of the Czech population. A total of 1 837 subjects (aged 5-98 years) took part in the study, randomly selected out of 38 147 people from the general population. H. pylori infection was investigated by means of a C-13-urea breath test. Breath samples in duplicates were analysed using isotope ratio mass spectrometry. The cut-off point was 3.5. Social and demographic characteristics were based on data from self-completed questionnaires. RESULTS: The overall prevalence of H. pylori infection was 23.5% (430/1826), and 4.8% (20/420) in children aged 15 or less. There was no statistically significant difference in prevalence between males (24.3%; 208/857) and females (22.9%, 222/969, P = 0.494). H. pylon infection was strongly associated with higher age, among subjects aged 55+ years, prevalence of H. pylori infection was 39.8% (252/633, P < 0.001). The highest prevalence of H. pylori infection was found among persons aged 55-64 years (43.9%, 97/221) and 75+ years (37.9%, 58/153). Among study subjects aged 15+ years, prevalence of H. pylori infection was significantly increased in those with lowest education (odds risk 3.19, 95% CI 1.87-5.47). Compared to never married (14.1%), the prevalence of H. pylori infection was statistically significantly higher among married (35.4%, 246/694, P < 0.001), divorced (36.8%, 49/133, P < 0.001) and widowed study subjects (40.2%, 45/112, P < 0.001), both in minimally and fully adjusted analysis. There was no significant difference in the prevalence of H. pylori infection between married and widowed subjects (35.4%, 246/694 vs 40.2%, 45/112, P = 0.389). There was little variation in smoking prevalence across categories of smoking and there was no evidence of an increased risk of H. pylon infection among current or past smokers in our data (odds risk 1.04 with 95% CI 0.78-1.40 for current smokers; odds ratio 0.83 with 95% CI 0.60-1.16 for former smokers). The current prevalence of H. pylori in 2011 was significantly lower compared to the prevalence reported from identical geographical areas in 2001 (23.5% vs 41.7%, P < 0.001). CONCLUSION: The overall prevalence of H. pylon infection in the general population has fallen substantially in the Czech Republic over the past 10 years.
