Epidemiology of Mental Health group (EPIOMH)

The group engages in epidemiological research in areas of relevance for public health. We value and foster links between science and society, well as research and practice. Our ultimate mission is to identify modifiable risk and prognostic factors for major contributors to the global burden of disease.

To keep up with new perspectives and have a “flow” in the group, we collaborate with several international researchers. The involvement of clinical and societal public health actors in our projects is also of importance. Other cornerstones are to maintain and further develop methodological skills and quality of data bases.

Research areas

  • Risk factors for psychiatric disorders: from fetal life until adulthood

  • Inflammation, infections, and autoimmune disorders and risk for psychiatric disorders such as schizophrenia, other psychotic disorders, and autism spectrum disorders
  • Acute and chronic stressors (e.g. socioeconomic factors, social disadvantage, migration) and risk for psychiatric disorders
  • Health and social outcomes in autism after adolescence
  • Use of antidepressants in pregnancy and offspring neurodevelopment
  • Health effects of smokeless tobacco (aka snus)
  • Life-course health effects of education
  • Impact of outdoor environment upon physical activity, sedentariness, UV radiation, stress, and general health at compulsory school
  • Determinants of type 2 diabetes, consequences, and related illness
  • Eating disorders – risk factors, occurrence, and health outcomes

Ongoing research projects

Risk factors for psychiatric disorders - from fetal life until adulthood - a program aimed at prevention

The etiology of psychiatric disorders remains elusive; however, accumulating evidence suggests a causal pathway comprising interaction between a constitutional genetic predisposition/vulnerability and key early life environmental exposures. There is varying scientific support for a number of modifiable exposures. Many of these environmental factors co-vary and may either confound or interact with each other. This means it is desirable to analyze all risk factors in conjunction with each other.

This program aims to advance current knowledge about key early life risk factors for psychiatric disorders by combining an epidemiological population-based approach with analyses of biological samples. The research questions as follows:

  1. Are individuals who develop psychiatric disorder exposed to certain risk factors during fetal life or childhood more often than comparison individuals?
  2. Do individuals who develop illness respond differently to risk exposures because of genetic vulnerabilities (including epigenetic changes)? The latter question is one of the next challenges for our group.

Sub projects

Early life inflammation and psychiatric disorders (e.g. ASD and psychoses): studies based on a combination of analyses of inflammatory markers in bio-samples (e.g. acute phase proteins, antibodies, cytokines) and in register data (occurrence of infections, autoimmune disorders, other inflammatory states) in Psychiatry Sweden. 
Migration and risk of psychiatric disorders (e.g. schizophrenia, other non-affective psychoses, ASD, suicides): Pre- and post- migration factors are analyzed as well as their interaction with general social determinants of health.
Social, economic, and physical environmental risk factors at different stages in life and psychoses risk: A multilevel, longitudinal investigation over the life course.
Advancing parental age and risk of psychotic disorders: scrutinizing the underlying mechanisms.
Perinatal risk factors  and risk of psychiatric disorders: Studies include risk due to fetal growth deviations, hyperemesis, Caesarean section, and maternal prescribed drug use.
Mental ill health during adolescence: occurrence, risk-factors, and use of mental health care.

Health and social outcomes in autism after adolescence
Autism spectrum disorders (ASD) are behaviorally defined neurodevelopmental disorders of heterogeneous and multifactorial origin. Their diagnostic boundaries are, however, debated.

Regardless of disputes over diagnostic issues, neurobiological correlates, and etiology, there is an increased pool of young people being diagnosed with ASDs. In fact, 2.7 percent of the current teenage population of Stockholm County has been diagnosed according to our recent work. This rapid increase in the occurrence of diagnosed ASD connotes a new public health scenario. How will this large group of individuals fare in the society of today? What measures will the health, educational, and social systems have to take to support them and their families? 

This project aims to elucidate adolescent and early adult health and social outcomes in individuals with ASD, in response to these questions. The research is conducted using the unique data compiled within the Stockholm Youth Cohort (SYC).

Disorders in eating – risk factors, occurrence, and future directions
Eating disorders (ED) are severe psychiatric disturbances with psychosomatic complications, mainly affecting young women. EDs have a peak age of onset in the mid-teens, affecting about 5-10% of young people when defined according to broad criteria. An even higher proportion is likely to suffer from disturbed eating behaviors (DEB); it is a commonly accepted fact that the number of unreported cases exceeds the number of diagnosed cases by far.

The female-to-male ratio for diagnosed EDs is 10 to 1. Few psychiatric disorders display such a skewed gender distribution, but the number of studies reporting on men with EDs is limited. The main purpose of the project is to estimate the prevalence of DEB in relation to psychiatric ill-health and diagnosed EDs in the Stockholm area. Further aims are to explore co-morbidity with, and excess mortality from, these conditions. Additionally, we want to investigate predictors of DEB and ED using main socio-economic and demographic factors from population registers. The project draws on data from the Stockholm Public Health Cohort (SPHC), regional register data from Stockholm County, and national register data. The project is run in collaboration with the Centre for Epidemiology and Community Medicine, Stockholm County Council.

Causal effects of education on life-course cognitive ability and dementia
In this project, the causal effect of education on dementia, and possible mediation via intelligence, will be assessed using two Swedish educational reforms during the 20th century as the exposure. The project is predominantly register-based but will also draw on cognitive test result data from different sources. In this project, we co-operate with researchers at the Aging Research Center.

Kidscape II - The outdoor environment of compulsory school and children´s health
A lack of physical activity and overexposure to solar UV radiation cause a number of preventable condition, and chance for physical activity and sun protection substantially contributes to reduced risk of illness related to these risks. The outdoor environment also impacts stress, night sleep, and infections.

These disparate risks may be reduced and health be promoted via exposure the outdoors. Preschool outdoor environment fulfilling certain criteria regarding vegetation, space, and topography is known to increase children’s physical activity by more than 20% while at the same time reducing sun exposure by 40%. Local governments are currently implementing upgrades to preschool outdoor environments. Kidscape II is a subsequent study that explores how school children use the outdoors.

The study thus aims at:

  1. examining if previous findings on preschool children also apply to older children
  2. creating evidence to be applied in physical planning of the outdoors that school children use during school time

School-based physical activity: Its intensity during physical education, theoretical class, and recess.
In Sweden, children and adolescents spend at least nine years at compulsory school. Compulsory school has a health-promoting potential by providing physical education and recess characterized by physical activity, but also by remodeling theoretical class by e.g., outdoor education.

The aims of this project are to:

  1. analyze the quantity and quality of total non-sedentary activity of physical education class vs. whole school day in terms of intensity and gender
  2. to analyze the quantity and quality of total non-sedentary activity of recess vs. whole school day in terms of intensity and gender,
  3. to analyze the quantity and quality of total non-sedentary activity of theoretical class vs. whole school day in terms of intensity and gender
  4. to evaluate the impact of physical education, theoretical class, and recess class upon second-, fifth-, and eight-graders' non-sedentary activity during the school day.

Determinants of type 2 diabetes, consequences, and related illness
In this follow-up of the Stockholm Diabetes Preventive Program (SDPP), biological, self-reported, and register data are collected on approximately 4000 people for the third time, 10 years since the last follow-up, and 20 years since baseline.

The project is led by the Centre for Epidemiology and Community Medicine, Stockholm County Council, and also involves clinicians at the Karolinska University Hospital, as well as other researchers at the Department of Public Health Sciences, the Department of Molecular Medicine and Surgery, and the Department of Medicine, Solna.

Stockholm Non-Affective Psychoses Study (SNAPS)
This register is built on routinely collected health care data from psychiatric outpatient and inpatient care, comprising of 13,561 adult persons, diagnosed with non-affective psychosis between 1997 and 2006. A large and well-defined catchment area of Stockholm County is covered, corresponding to over 1.1 million inhabitants of the total adult population in Stockholm County.

This register has so far been used to estimate incidence and prevalence of psychotic disorders in Stockholm County, and is now a part of Psychiatry Sweden. On-going studies concern risk factors for and consequences of psychotic disorders.

Contact person: Christina Dalman

The Stockholm Youth Cohort (SYC
The SYC as register-based total population study, including approximately 735 000 young people in Stockholm County. An exhaustive multi-source linkage with official registries covering all pathways of assessment, care, or special education for psychiatric disorders has been performed.  Ongoing research projects include studies of causes and consequences of child and adolescent mental disorders, in particular autism spectrum and eating disorders.

The Stockholm Public Health Cohort
The Stockholm Public Health Cohort is a prospective study set within the framework of the Stockholm County Council public health surveys of 2002, 2006, and 2010. The surveys involved random samples of the general population of Stockholm County above 18 years. To date, the study comprise almost 90 000 participants. Respondents that were recruited in 2002 were followed-up in 2007. In 2010, a new wave of data collection was conducted, including a cross-sectional sample of the general population of Stockholm County, and a follow-up study of the participants enrolled in the 2002 and 2006 surveys. Participants have given their informed consent to the preservation of their national registration number, future contacts, and record linkages. A further wave of data collection is planned for 2014. The study is funded by the Stockholm County Council and is governed in collaboration between Karolinska Institutet and the County Council’s Centre for Epidemiology and Community Medicine.
