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.
Maryland health officials issue new vaccine guidance - WBAL
In Maryland, more than 96% of kindergarteners are up to date on their childhood vaccinations. Seasonal shots like flu and COVID-19 vaccines are not required but are encouraged annually.
What Do We Actually Know About Kids on Weight-Loss Drugs?
Between 2019 and 2026, the researchers found, 0.6% of children ages 8 to 11 with obesity but without diabetes had been prescribed an off-label GLP-1, while the annual percentage of such children prescribed a GLP-1 dramatically increased year ...
Research of the Day
Inhaled Corticosteroid Adherence in Minority Children: Community Health Worker Intervention
This RCT evaluated community health worker (CHW) home visits to improve inhaled corticosteroid adherence in 400 minority children with persistent asthma. CHW intervention nearly doubled medication adherence rates.
Key findings: (1) Adherence improved from 45% to 82% in intervention group; (2) 50% reduction in asthma-related ED visits; (3) Culturally tailored education more effective than standard approach.
Consider CHW programs or similar support for families struggling with asthma medication adherence. Address social determinants and provide culturally appropriate education.
Popular Beliefs
Warm milk helps children sleep
What the evidence shows: While milk contains tryptophan (a sleep-promoting amino acid), the amount is modest. Any sleep benefit likely comes from the comforting ritual and warmth rather than pharmacologic effect. A consistent bedtime routine matters more than any single component.
Remove ticks with a lit match or petroleum jelly
What the evidence shows: These methods can cause the tick to regurgitate into the wound, increasing disease transmission risk. Use fine-tipped tweezers to grasp the tick close to the skin and pull upward with steady pressure. Save the tick for identification if possible.
Letting babies walk early causes bowlegs
What the evidence shows: There is no evidence that early walking causes bowlegs. Most infants have some degree of bowing that typically resolves by age 3-4. Pathologic bowing has other causes (Blount disease, rickets). Encourage normal motor development and monitor for asymmetric or progressive bowing.
Behaviors
Physical Activity and Academic Achievement: School-Based Intervention Study
This cluster RCT examined whether increasing physical activity during the school day improved academic outcomes in 3,500 elementary students. Schools were randomized to add 30 minutes of daily activity or continue standard curriculum.
Key findings: (1) Intervention students showed 15% improvement in reading scores; (2) Math scores improved 8%; (3) On-task behavior increased and disruptive behavior decreased. Benefits were greatest for students with ADHD symptoms.
Advocate for physical activity in schools—it enhances rather than detracts from learning. Counsel families on the importance of daily active play for cognitive development, not just physical health.
Genetics
Genetic Risk Screening for Type 1 Diabetes: Prevention Trial Update
Large-scale genetic screening of newborns identifies high-risk children for T1D prevention trials. Early results suggest immune modulation in high-risk children may delay or prevent onset of diabetes.
Key findings: (1) 5% of screened infants fall into high-risk category; (2) Early intervention delayed onset by average 3 years; (3) Screening acceptable to most families when explained appropriately.
T1D prevention is moving from research to clinical reality. Stay updated on trial availability. For families with T1D history, genetic counseling and risk assessment may be appropriate for siblings.
