BACKGROUND: Studies of adoptees have the potential to disentangle the contributions of genetic versus family environmental factors in the familiar transmission of coronary heart disease (CHD) because adoptees do not share the same family environment as their biological parents. The aims of this study were as follows: (1) to examine the risk of CHD in adopted men and women with at least one biologi

Neighbourhood deprivation has been implicated in lung cancer but no study has simultaneously analysed the potential effect of neighbourhood deprivation on both lung cancer incidence and mortality, after adjusting for individual-level socioeconomic factors, and comorbidities. The aim of the present study was to analyse whether there is an association between neighbourhood deprivation and incidence

Caloric restriction has been found to be protective against the development of type 2 diabetes mellitus (T2D) in experimental animal studies. However, studies examining this association in humans are limited. In the present study, we examined whether individuals with anorexia nervosa, one marker of severe caloric restriction in humans, have a low incidence of T2D by using several Swedish registrie

Population-based data on metastatic sites and survival in site-specific metastases are lacking for lung cancer and for any cancer because most cancer registries do not record metastases. This study uses a novel population-based approach to identify metastases from both death certificates and national inpatient data to describe metastatic pathways in lung cancer patients.

Both epidemiological and genetically informative studies indicate that shared environmental influences contribute to resemblance in siblings for drug abuse (DA). To what degree do these influences arise from living in the same household versus residing in the same community? We performed a cross-classified multi-level logistic regression on all individuals born in Sweden 1975-1990 (N = 1558,654).

To examine whether neighborhood deprivation increases the odds of hospital registration for childhood and adolescent epilepsy, after accounting for family- and individual-level sociodemographic characteristics.

Cancer of unknown primary (CUP) is diagnosed at the metastatic stage and despite extensive diagnostic work-up the primary tumor often remains unidentified. Limited population-based survival data are available for metastatic location and none are available that link the location with the cause of death, which might give clues about the tissue of origin. A total of 9,306 CUP patients with extranodal

Objectives: Socio-economic and occupational factors may contribute to risk of immune-mediated disorders. The importance of these factors in giant cell arteritis (GCA) is unknown. This is the first nationwide study with the aim of investigating possible associations between socio-economic status (SES)/occupation and hospitalization for GCA. Method: A nationwide database was constructed by linking S

Context: Previous studies of the association between schizophrenia and cancer have produced conflicting results, probably because of the failure to control for confounding factors. Objective: To test if the possible association between schizophrenia and cancer is genetic by investigating the incidence of cancer in patients with schizophrenia and their relatives. Design: Retrospective cohort stud

Objective: The authors sought to clarify the sources of parent-offspring resemblance for drug abuse, alcohol use disorders, and criminal behavior, using a novel genetic-epidemiological design. Method: Using national registries, the authors identified rates of drug abuse, alcohol use disorders, and criminal behavior in 41,360 Swedish individuals born between 1960 and 1990 and raised in triparental

Prior studies, utilizing interview-based assessments, suggest that most of the genetic risk factors for drug abuse (DA) are non-specific with a minority acting specifically on risk for abuse of particular psychoactive substance classes. We seek to replicate these findings using objective national registry data.

Data concerning the importance of family history of venous thromboembolism (VTE) for the risk of recurrent VTE are sparse. The aim of this nationwide study was to determine whether family history of VTE is a risk factor for recurrent hospitalization for unprovoked VTE (deep venous thrombosis of the lower extremities or pulmonary embolism).

BACKGROUND: Earlier studies have suggested that type 2 diabetes mellitus (T2DM) alters the risk of developing a variety of cancers, but little has been known about the impact of T2DM on cancer prognosis. On the basis of nationwide population-based Swedish registries, the authors of this report compared the cause-specific survival among cancer patients with and without T2DM. METHODS: Patients with

It is known that overweight is associated with chronic knee pain (CKP) and chronic low back pain (CLBP). Several risk factors for these conditions have been postulated, including age, sex, overweight, occupation, and socioeconomic factors. In addition, physical environment has been studied as a potential risk factor in recent years. However, the associations of overweight and physical environment

Infectious etiologies have been hypothesized for acute leukemias because of their high incidence in early childhood, but have seldom been examined for acute myeloid leukemia (AML). We conducted the first large cohort study to examine perinatal factors including season of birth, a proxy for perinatal infectious exposures, and risk of AML in childhood through young adulthood. A national cohort of 3,

Cigarette smoking is associated with amyotrophic lateral sclerosis (ALS), but the association between alcohol consumption and ALS is not clear. Our aim was to clarify this using a national cohort study design in Sweden.

Attention-deficit/hyperactivity disorder (ADHD) predisposes to drug abuse (DA) and twin studies suggest shared genetic effects. We here seek to determine, using adoption and adoption-like samples, the magnitude of the cross-generational transmission from DA in parents to ADHD in their children and clarify the degree to which this arises from genetic v. rearing effects.

Genetic variants associated with venous thromboembolism (VTE) have been suggested to be involved in the pathogenesis of pre-eclampsia/eclampsia (PEC/EC). This nationwide study aimed to determine whether VTE shares familial susceptibility with PEC/EC.

Risk and Vulnerability Assessments (RVA) are performed on many levels of society by many different organisations. In the present paper we discuss how one can investigate if a system for RVA used in a country or a region fulfils its intended purpose. We show how the purpose of the Swedish system can be related to the actual form of the individual RVA documents. This is followed by a content analysi

Risk for drug abuse (DA) is strongly associated with neighborhood social deprivation (SD). However, the causal nature of this relationship is unclear.
