A new series of papers in The Lancet argues that excessive screen time is a public health emergency requiring global regulation. The review of nine million participants links problematic digital use to mental health issues, poor sleep, and reduced physical activity. Experts call for tech companies to share user data and governments to enforce safety standards, comparing the situation to the tobacco industry's history.
New research published in The Lancet and JAMA Pediatrics indicates that excessive screen time is linked to significant negative outcomes for children, including poor sleep, mental health issues, and lower academic achievement. While experts agree on the harms, there is debate over the severity and the role of parental responsibility versus corporate accountability. Governments and tech companies are facing pressure to implement stricter regulations and data transparency measures to protect young users.
A massive umbrella review involving over 2.8 million children across 64 countries finds that high screen time is associated with lower academic achievement, poorer language development, and increased mental health issues. Published in JAMA Pediatrics, the study led by the University of Calgary notes these effects are comparable to or larger than those of parental behavior and premature birth. However, experts caution that the study cannot distinguish between different types of screen use or prove causation, and some argue the findings do not support the idea that screens are the primary cause of adolescent distress.
A Canadian longitudinal study of 501 families found that mothers' unresolved childhood trauma significantly impacts their children's adult outcomes. The research indicates that maternal trauma correlates with lower socioeconomic status and reduced emotional attunement, which in turn predicts higher rates of anxiety, depression, rule-breaking behavior, and academic difficulties in their offspring. The findings support the 'interactionist model' of development, suggesting trauma creates a cascade of risk affecting family dynamics and child development.
A massive umbrella review involving nearly 3 million children across 64 countries finds that high screen time is associated with lower academic achievement, poorer language development, and increased mental health problems. The study, led by the University of Calgary and published in JAMA Pediatrics, notes that these effects are comparable to or larger than those of parental behavior and premature birth. However, experts caution that the study cannot distinguish between different types of screen use or prove causation, and some argue the findings do not support the idea that screens are the primary cause of adolescent distress.
A new study published in JAMA Network Open finds that US adolescents who owned a smartphone at age 12 were significantly more likely to report eating disorder symptoms by age 14. The research, based on nearly 9,000 participants, highlights a correlation between early device access and disordered eating behaviors, though it does not prove causation. Experts advise parents to delay smartphone introduction and implement strict usage guardrails to protect children's mental health during puberty.
A Japanese study of 113 preschoolers found that higher spontaneous eye-blink rates correlate with better performance on cognitive flexibility tasks and increased activity in the right dorsolateral prefrontal cortex. Researchers suggest blink rate could serve as a simple, non-invasive marker for tracking executive function development in children aged 3 to 6.
A mother recalls how her children’s early fascinations—sharks, photography, filmmaking, and other creative pursuits—often foreshadowed their eventual careers, and she reflects on supporting their interests even when outcomes diverged from her initial predictions.
A BuzzFeed Health piece gathers pediatricians’ insights on 15 common health myths parents should stop believing about kids, ranging from iron intake and vaccines to screen time and toilet training, and emphasizes evidence-based guidance, regular checkups, and early intervention when delays appear.
A study following more than 300 mother–child pairs found that prenatal inflammation raises ADHD symptoms in early childhood, but warm, responsive parenting in infancy can offset this risk by shaping brain development and suggesting potential interventions such as fatty acids or mindfulness.
A Space Daily article summarizes Judy Y. Chu’s ethnographic study of six boys from ages four to six, noting that children in this window are highly perceptive and openly expressive, but over the next two years they become more guarded as they learn to align with masculine norms that de-emphasize warmth. The piece connects these findings to similar patterns observed in girls and later adolescence, while stressing that the research is not a causal a priori and does not predict individual outcomes.
A Norwegian study of over 37,000 children found that exclusive breastfeeding for up to six months is associated with lower ADHD symptoms at ages 3, 5, and 8, with stronger effects in girls; any breastfeeding helps, but longer exclusive duration shows greater benefits, though the study is observational and cannot prove causation, prompting calls for further research.
A study from Inserm and the National University of Singapore, backed by the WHO and the American Academy of Pediatrics, reports that high screen time during infancy and school-entry age is associated with poorer later academic performance and weaker working memory, with effects most pronounced around age six; a separate UK study from iADDICT links under-two screen exposure to adverse health outcomes and calls for a baby screen-time risk assessment, underscoring that limiting early screen time and modeling healthy habits is important while acknowledging limited, supervised use in some contexts.
A study of over 8,000 mothers finds that poorer cardiovascular health is associated with higher rates of developmental delays in children by age 4 (8.8% delays for high‑cardiovascular-health moms vs 16.8% for low‑health moms), a 62% increased risk. Delays affected communication, motor, and social skills. Experts urge improving heart health before and during pregnancy through diet (Mediterranean), regular exercise, adequate sleep, and avoiding smoking to potentially improve lifelong outcomes for both mother and child.
A Penn State study of 129 mother–child pairs found that harsh parenting undermines the natural shift toward self-regulation in preschoolers by increasing external biological regulation and slowing stress recovery, as measured by respiratory sinus arrhythmia (RSA). Less-harsh parenting shows the mother’s physiological influence waning with age, while harsher parenting leads to greater RSA inertia and stronger reliance on caregiver regulation, highlighting intergenerational risk for regulatory problems and suggesting self-regulation as an intervention target.
