Article Synopsis
- Longitudinal cohort studies are crucial for understanding how various factors impact health by tracking participants over time, but maintaining participant engagement over decades is challenging.
- This study examined participant engagement and involvement (PEI) practices in different cohort studies across Europe, Australia, and New Zealand, using interviews to gather insights on recruitment, consent, communication, and data collection.
- Findings revealed diverse recruitment strategies, a shift towards digital data collection methods, and attempts to involve participants in decision-making through advisory panels, although success varied by age and socio-economic status.
Article Synopsis
- A study examined eating problems among adolescents during the pandemic compared to before, using data from 22,706 14-16-year-olds over six years.
- Results indicated that while all adolescents showed an increase in eating problems over time, the pandemic uniquely affected girls, who reported higher levels of dieting and body dissatisfaction during this period.
- The findings emphasize the need to address gender-specific issues related to eating problems and suggest that factors like screen time and mental distress may have worsened during the pandemic.
Article Synopsis
- Researchers analyzed genetic data from nearly 130,000 cancer patients and over 730,000 healthy controls to identify variants linked to cancer risk across 22 cancer types.
- Four high-risk genes were found: BIK (prostate cancer), ATG12 (colorectal cancer), TG (thyroid cancer), and CMTR2 (lung cancer and melanoma).
- Additionally, two genes, AURKB (general cancer risk) and PPP1R15A (breast cancer), were associated with decreased cancer risk, indicating potential pathways for cancer prevention strategies.
Article Synopsis
- Childhood and adolescence often see the emergence of mood and anxiety disorders, with overlapping genetic factors potentially influencing emotional and behavioral difficulties.
- The study analyzed data from over 54,000 children in the Norwegian Mother, Father, and Child Cohort to discern how genetic predispositions (polygenic scores) relate to development patterns of these disorders.
- Results indicated that higher genetic risk correlates with a baseline increase and accelerated progression of behavioral issues, while specific genetic profiles linked uniquely to certain emotional disorders were identified.
Article Synopsis
- Some studies have suggested that drinking coffee during pregnancy might affect how kids develop, but the results have been mixed.
- This study looked at the link between mothers' and fathers' coffee consumption before and during pregnancy, and how it relates to children's development issues.
- The findings showed a connection between moms who drank coffee and some behavioral challenges in kids, but when factors like smoking and education were considered, the link became weaker.
