7/7 This work was brilliantly led by Herman Skillebæk and also many thanks to co-authors Mona Bekkhus and Ragnhild Eek Brandlistuen.

6/7 These findings highlight symptom-specific associations between bullying experiences and anxiety and depression in adolescence and suggest that supportive parent-child relationships may influence the strength of these connections.

5/7 Furthermore, one edge (i.e., association) linking bullying and symptoms was moderated by parent-child relationship quality: the association between bullying and feeling scared was weaker at higher levels of parent-child relationship quality.

4/7 Using a Moderated Network Model (see www.tandfonline.com/doi/full/10....), we found that feeling blue was the symptom most strongly connected to bullying, and that different bullying experiences exhibited varying associations with individual symptoms of anxiety and depression.

3/7 Here, we used data from adolescents enrolled in MoBa (N = 21,308) to assess associations between multiple bullying experiences and symptoms of anxiety and depression, as well as symptom-level moderation effects by parent-child relationship quality.

2/7 Bullying is a well-established risk factor for internalising problems in adolescence. Some research suggests parent-child relationships may buffer the impact of bullying on mental health, but moderation effects at the symptom-level remain unexplored.

Ny studie: Nesten hvert fjerde barn viser symptomer på spiseforstyrrelser – For et mindretall er dette ikke vanlig kresenhet, men en spiseforstyrrelse som kan ha negative konsekvenser for både fysisk og psykisk utvikling, sier forsker Ludvig Daae Bjørndal.

Jeg ble nylig intervjuet av Aftenposten om vår nye artikkel om symptomer på unngående restriktiv spiseforstyrrelse (ARFID)

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.
