However, vaccination coverage among U.S. kindergartners has decreased from 95.2% during the 2019–2020 school year to 92.4% in the 2025–2026 school year, leaving approximately 280,000 kindergartners at risk during the 2025–2026 school year.

Research of the Day
Social Media Use and Depression in Early Adolescence: Longitudinal Analysis
This 3-year longitudinal study followed 6,500 adolescents ages 12-15, tracking social media use patterns and mental health outcomes. High social media use (>3 hours/day) was associated with increased depression risk, though the relationship was bidirectional.
Key findings: (1) 35% increased odds of elevated depressive symptoms with high use; (2) Social comparison and cyberbullying mediated the relationship; (3) Active use (creating content) showed smaller associations than passive consumption.
Screen for problematic social media use during well visits. Counsel families on media limits, encourage active over passive use, and discuss warning signs of cyberbullying and unhealthy comparison.
Popular Beliefs
Eating carrots dramatically improves vision
What the evidence shows: While carrots contain vitamin A important for eye health, eating extra carrots won't improve normal vision or eliminate the need for glasses. Vitamin A deficiency can cause vision problems, but this is rare in developed countries with varied diets.
Teething causes high fevers and diarrhea
What the evidence shows: While teething may cause mild symptoms (gum irritation, drooling, slight temperature elevation), it does not cause high fever (>102°F/38.9°C) or diarrhea. These symptoms should prompt evaluation for other causes. Attributing significant illness to teething may delay diagnosis of serious conditions.
Sugar makes children hyperactive
What the evidence shows: Multiple double-blind, placebo-controlled studies have found no significant effect of sugar on behavior or cognitive performance in children, even in those reportedly 'sensitive' to sugar. The perceived hyperactivity is often due to the context (parties, holidays) or parental expectations. However, limiting added sugars remains important for dental health and nutrition.

Family Meal Frequency and Obesity Risk: Systematic Review and Meta-Analysis
This meta-analysis synthesized 45 studies examining the relationship between family meal frequency and childhood obesity. Children who shared regular family meals had significantly lower obesity risk and healthier eating patterns.
Key findings: (1) 3+ family meals/week associated with 12% lower overweight/obesity; (2) Higher fruit/vegetable intake and lower fast food consumption; (3) Protective effect independent of family structure or income.
Encourage family meals as part of healthy lifestyle counseling. Even a few shared meals per week make a difference. Focus on the ritual and connection, not just nutrition.
Genetics
Polygenic Risk Scores and ADHD: Clinical Utility Analysis
Large GWAS analysis demonstrates polygenic risk scores for ADHD have limited current clinical utility for diagnosis but may help identify children at risk for severe or persistent symptoms. Environmental factors remain critically important.
Key findings: (1) Polygenic scores explain ~10% of ADHD variance; (2) Higher scores associated with earlier onset and persistence; (3) Not useful as diagnostic test—clinical evaluation remains gold standard.
Genetics is one piece of the ADHD puzzle but doesn't replace clinical assessment. Avoid overinterpreting direct-to-consumer genetic tests. Family history remains the most useful genetic 'test' for ADHD risk.
