Neuroticism Genetic Risk, Gender, and Economic Disadvantage

Polygenic indices (PGIs) offer a tool for estimating genetic predispositions to personality traits such as neuroticism. Using genetic, survey, and registry-linked data from six Finnish cohorts (1992–2017; N = 20,121; ages 25–64), we examined how the Neuroticism Polygenic Index (NPGI) relates to a sequence of econom...

Population scale analysis reveals gut microbiome diversity and functional shifts linked to obesity

Summary This study investigated the relationship between the gut microbiota and two obesity indicators, body mass index (BMI) and waist-hip ratio (WHR) in a well-phenotyped random population sample of 5846 participants. Associations were tested using multivariable-adjusted linear models and validated for BMI in an exte...

Importance of faecal sample collection in prospective cohort studies to evaluate the effect of the gut microbiome on cancer development.

The gut microbiome has been linked to cancer in many cross-sectional studies. These studies compared individuals with and without cancer, but they do not establish causation. Prospective cohort studies, with faecal samples collected before a cancer diagnosis, will be instrumental in assessing the role of the gut microb...

Associations of ADHD genetic risk with objective and subjective economic wellbeing: evidence from finnish population-based cohorts.

PURPOSE This study examines how genetic liability for Attention-Deficit/Hyperactivity Disorder (ADHD), measured using a polygenic index (ADHD-PGI), relates to both objective and subjective socio-economic outcomes in the general population. METHODS We studied six Finnish population-based cohorts (1992-2017; N = 20,121...

Circulating Metabolites Are Biomarker Candidates for Stroke Risk Prediction: Results From the BiomarCaRE Project.

BACKGROUND Stratification of stroke risk remains challenging, but metabolomic profiling offers the potential to detect new biomarkers and to improve early risk assessment of incident stroke. The objective of this study was to evaluate the association between circulating metabolites and the incidence of stroke in a case...

A spectrum of gut microbiota signatures predicts long-term health status

It is demonstrated that robust signatures of co-abundant species can be prospectively associated with mortality, diabetes, liver disease, and sepsis risk among Finnish adults in the FINRISK population cohort based on a 20-year follow-up.
