Research of the Day
School Start Times and Adolescent Mental Health: A Natural Experiment
This natural experiment followed 50,000 high school students before and after a district-wide shift to later school start times (8:30am vs 7:15am). Students gained an average of 45 minutes of sleep per night and showed significant improvements in mental health markers over the 2-year study period.
Key findings: (1) 27% reduction in depressive symptoms; (2) 34% decrease in suicidal ideation reports; (3) Improved academic performance and attendance. Effects were most pronounced in students getting 8+ hours of sleep.
These data support advocating for developmentally appropriate school start times. Middle and high school students need 8-10 hours of sleep—counsel families on sleep hygiene and the importance of adequate rest for mental health.
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.
Starve a fever, feed a cold
What the evidence shows: Neither fevers nor colds benefit from restricting food. Both conditions increase metabolic demands, and adequate nutrition supports immune function. Encourage normal eating as tolerated and emphasize hydration with any illness.

Screen Time and Executive Function in Preschoolers: A Longitudinal Analysis
This prospective cohort study followed 850 children from ages 2 to 5 years, examining the relationship between screen time exposure and executive function development. Researchers used validated parent-report measures and direct assessments of working memory, inhibitory control, and cognitive flexibility.
Children with more than 2 hours of daily screen time at age 2 showed lower scores on executive function measures at age 5. Notably, the type of screen content mattered—educational programming showed smaller associations than passive entertainment viewing. Joint parent-child viewing partially mitigated negative effects.
These findings support counseling families on the AAP recommendation of less than 1 hour per day of high-quality programming for children 2-5 years. Emphasize co-viewing and educational content when screens are used. Executive function is crucial for school readiness and later academic success.
Genetics
Familial Hypercholesterolemia Screening in Childhood: Cascade Screening Effectiveness
Cascade screening for familial hypercholesterolemia starting in childhood identifies affected relatives and enables early statin therapy. Children identified through family screening had better outcomes than those diagnosed after cardiac events.
Key findings: (1) Each identified case led to 3 additional diagnoses in relatives; (2) Early statin therapy (age 8+) reduced lifetime cardiovascular risk; (3) Universal lipid screening at ages 9-11 complementary to cascade screening.
Take family history of premature heart disease seriously. Screen children in affected families by age 2. Universal lipid screening should occur at 9-11 years per AAP guidelines.
