Maladaptive impulsivity and compulsivity predispose to antisocial and addictive behaviours. Factors influencing those traits are not well understood, but diet, lifestyle, socioeconomic status (SES), sex, and heritability play pivotal roles. Here, we aim (1) to identify nutrition and lifestyle drivers that can be employed to prevent detrimental impulsivity/compulsivity in males and females across the lifespan, (2) to characterize the etiologic paths leading to extreme behaviour, and (3) to promote policy changes to counteract maladaptive impulsivity/compulsivity by disseminating evidence-based information about health-related behaviours to families, clinicians, policy makers, and general public. We use epidemiologic approaches in the world-wide largest existing samples to investigate association of nutrition components & lifestyle with impulsivity/compulsivity, and how such associations are moderated by age, culture, sex, SES, and genetics. We assess beneficial effects of key nutritional interventions through RCTs in highly impulsive males/females, going beyond state-of-the-art by directly comparing personalized, high-intensity approaches with one-size-fits-all and microbiome-dependent supplementations. We study the protective potential of acute exercise and habitual physical activity. We monitor intervention-induced changes in real time through objective mHealth-based experience sampling. Uniquely, we study effects of the gut-microbiome and its metabolites, as well as brain connectivity and epigenetic patterns as mediators and predictors of behavioural change. We initiate and support societal change by media-based information and education. We innovate the field by measuring behavioural change using social media downstream of educational campaigns and by translation of our findings into tangible healthy food solutions with a celebrity chef. Our group, in which experts from multiple disciplines join forces, is in a unique position to carry out the proposed project.

Driving risks of young drivers with symptoms of attention deficit hyperactivity disorder: association with the dopamine transporter gene VNTR polymorphism
(2022)Road traffic injuries are a leading cause of death for young adults, and young drivers with higher expression of symptoms of attention deficit-hyperactivity disorder (ADHD) could pose an even greater risk in traffic. ... -
Variation rs6971 in the Translocator Protein Gene (TSPO) Is Associated with Aggressiveness and Impulsivity but Not with Anxiety in a Population-Representative Sample of Young Adults
(2021)Expression of the 18-kDa translocator protein (TSPO), originally identified as a peripheral benzodiazepine receptor, has been found to be altered in several psychiatric disorders. A common single nucleotide polymorphism ... -
Interactive effects of DRD2 rs6277 polymorphism, environment and sex on impulsivity in a population-representative study
(Elsevier, 2021-04)Previous research has shown that dopaminergic dysregulation and early life stress interact to impact on aspects of impulse control. This study aimed to explore the potentially interactive effects of the rs6277 polymorphism ... -
Variants of the aggression-related RBFOX1 gene in a population representative birth cohort study: aggressiveness, personality and alcohol use disorder
(2020)Background Recently RBFOX1, a gene encoding an RNA binding protein, has consistently been associated with aggressive and antisocial behaviour. Several loci in the gene have been nominally associated with aggression ... -
Neuropeptide Y gene variants in obesity, dietary intake, blood pressure, lipid and glucose metabolism: a longitudinal birth cohort study
(Elsevier, 2021)Objective: Neuropeptide Y affects several physiological functions, notably appetite regulation. We analysed the association between four single nucleotide polymorphisms (SNP) in the NPY gene (rs5574, rs16147, rs16139, ... -
The role of reward sensitivity in obesity and its association with Transcription Factor AP2B: a longitudinal birth cohort study
(Elsevier, 2020)Objective One factor potentially contributing to obesity is reward sensitivity. We investigated the association between reward sensitivity and measures of obesity from 9–33 years of age, paying attention to the inner ... -

(Cambridge University Press, 2020)Objective: Reward sensitivity is an increasingly used construct in psychiatry, yet its possible inner structure and relationship with other affective variables are not well known. Methods: A reward sensitivity ... -
Association of FTO rs1421085 with obesity, diet, physical activity and socioeconomic status: a longitudinal birth cohort study
(2020)Background and aims Fat mass and obesity-associated protein (FTO) variants are among genetic variants frequently associated with obesity. We analyzed the association between FTO rs1421085 polymorphism and obesity, dietary ... -
Low cholesterol levels in children predict impulsivity in young adulthood
(2019)Objective: Severe behavioural issues such as impulsive action and suicide have since long been associated with low levels of cholesterol. While it is known that cholesterol plays a role in neural development and hence low ... -
Orexin/hypocretin receptor gene (HCRTR1) variation is associated with aggressive behaviour
(ScienceDirect, 2019-09)Orexins, alternatively called hypocretins, are neuropeptides with crucial role in maintaining wakefulness. The orexin system is thought to mediate a coordinated defense response but thus far investigated from the flight, ... -
Efficacy of intervention at traffic schools reducing impulsive action, and association with candidate gene variants
(Acta Neuropsychiatrica, 2019)OBJECTIVE: Road traffic injuries are the leading cause of death among young people. Recognition of the contribution of impulsive behaviour may help novice drivers to behave more safely. Previously a brief intervention ... -
