Research of the Day
Probiotics for Infantile Colic: Randomized Controlled Trial of L. reuteri
This double-blind RCT enrolled 400 breastfed infants with colic to evaluate Lactobacillus reuteri supplementation. Infants receiving the probiotic showed significantly reduced crying time compared to placebo, with effects observed within 7 days of treatment initiation.
Key findings: (1) Mean crying time reduced by 51 minutes/day at 21 days; (2) 73% of treatment group had crying <3 hours/day vs 36% placebo; (3) No adverse events reported. Effect was specific to breastfed infants.
L. reuteri may be considered for breastfed infants with colic after excluding other causes. This is one of several evidence-based interventions alongside feeding adjustments, carrying techniques, and parental support.
Popular Beliefs
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.
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.
ADD/ADHD is caused by poor parenting or too much sugar
What the evidence shows: ADHD has strong genetic and neurobiological components. While environment can influence symptom severity, poor parenting and diet do not cause ADHD. Evidence-based treatments include behavioral therapy and, when appropriate, medication. Blaming parents is harmful and delays effective intervention.
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
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.
