New risks of picky eating in kids revealed The study of over 35,000 children found that restricted eating has serious nutritional consequences for about 2–3 percent of kids.

Nice summary of our new paper on avoidant restrictive eating in Newsweek

I am really grateful to a fabulous team who has contributed to this work for more than 2 years, with expertise across eating disorders, epidemiology, developmental psychology, and genetics. Thank you! 💫

In sum, we identify high prevalence of ARFI in the general pediatric population, with elevated risk of more developmental difficulties for affected children. This is indicative of the need for broad support interventions. Finally, our findings advance understanding of genetic underpinnings of ARFI.

We subsequently conducted multiple genetic analyses. SNP-h2 ranged from 8-16%. Two genome-wide loci were identified and, for ARFI-clinical, an association with ADCY3. Small to moderate genetic correlations were observed across ARFI and numerous complex trait phenotypes.

We assessed numerous characteristics from socio-emotional and behavioral domains from 6 months years to 14 years. Across these timepoints, children with ARFI-broad persistent exhibited more developmental difficulties compared with children with no avoidant/restrictive food intake phenotypes.

Of children with data at 3 and 8 years (35,751), 32% were classified with any broad ARFI: 6% persistent, 18% transient, and 8% emergent. Prevalence of ARFI and at least one clinical indicator was 2% for persistent, 3% for transient, and 1% for emergent (6% in total).

We constructed avoidant/restrictive food intake (ARFI) phenotypes based on 3 and 8 year data, including transient (only 3), emergent (only 8), and persistent (both 3 and 8). Furthermore, we integrated symptom and registry data to identify multiple indicators of clinical significance.

Excited to share our new paper on avoidant/restrictive food intake, a core symptom of ARFID, just out in @jamapediatrics.com

We highlight its prevalence, associated developmental characteristics from 6 months through 14 years, and genetic associations.

A large population-based study in Norway found substantial prevalence of avoidant/restrictive food intake patterns, with affected children at higher risk for developmental challenges and neurodevelopmental diagnoses. ja.ma/4p8ZQ8s

Results from study of mental health in 92 countries (n>53,000): People are not doing well.

- U-shape for age is gone: Young adults lowest health, highest illness
- Education still matters (a lot)
- 45% of older people live alone
- Hybrid work > 100% remote or in-person

5/6. This paper follows several articles in which we show how risk factors exhibit granular associations with mental disorder symptoms. Such relationships can be overlooked when global measures, such as (symptom) sum scores, are used.

4/6. We describe three key findings:

1️⃣ Several symptom-specific associations were discernible.
2️⃣ Depressive symptoms were more strongly tied to financial adversity compared with anxiety.
3️⃣ Hopelessness about the future was most strongly connected to financial adversity.

3/6. We incorporate multiple subjectively assessed financial factors (e.g., ability to cope with unforeseen expenses) and register-based financial data (e.g., income, assets).

2/6. We apply a systems-based approach to identify symptom-specific relationships. Why? Financial adversity is complex and multidimensional and may exhibit granular associations with specific mental disorder symptoms (i.e., different mental health experiences).

New paper! 📜 In nearly 50,000 individuals randomly sampled from the general population, we apply a symptom-specific perspective to examine which anxiety and depressive symptoms are most strongly associated with various aspects of financial adversity

An abbreviation (ABB) in a journal article (JA) or Grant Application (GA) is rarely worth the words it saves. Every ABB requires cognitive resources (CR) and at my age by the time I'm halfway through a JA or GA I no longer have the CR to remember what your ABB stood for.

Stress Resilience and Risk of Psychiatric Disorders After Childhood Bereavement

Stress Resilience and Risk of Psychiatric Disorders After Childhood Bereavement

Childhood bereavement was associated with an increased risk of psychiatric disorders in adulthood, partly due to changes in stress resilience measured in late adolescence. https://ja.ma/44jTkEo

(8/9) Still, our findings suggest that altered stress resilience is one mechanism linking childhood loss of a parent or sibling to psychiatric disorder risk in adulthood.

This is among the most comprehensive longitudinal studies on childhood bereavement and mental health across decades of life.

(7/9) There are some important limitations: We lack information about the resilience measure and only one measurement was available. Generalisability is also uncertain, with strong assumptions underlying causal mediation analysis, pointing to the need for triangulation across methods.
