---
name: eso-pediatric-obesity-physical-activity
description: Prescribes physical activity for pediatric obesity prevention and treatment in children and adolescents with BMI at or above the 85th percentile. Recommends at least 20 minutes, optimally 60 minutes, of vigorous physical activity on ≥5 days per week to improve metabolic health and reduce obesity risk.

# Prescribe physical activity for pediatric obesity prevention/treatment

## STEP 1 — Gather Information
Collect age, sex, BMI percentile, current physical activity level (minutes/day, days/week, intensity), comorbidities (orthopedic, cardiovascular, pulmonary), barriers to activity, and patient/family preferences for activities.

## STEP 2 — Rule In / Rule Out
Is the patient aged 2–18 years with BMI ≥85th percentile?  
- Yes → Proceed to step 3.  
- No → Physical activity prescription for obesity prevention/treatment not indicated; consider general health promotion or other indications.

## STEP 3 — Classify or Stratify
Classify current vigorous activity:  
| Current activity | Classification |
|------------------|----------------|
| <20 min vigorous activity <5 days/week | Insufficient |
| ≥20 min vigorous activity ≥5 days/week | Sufficient (maintain) |

## STEP 4 — Decide
If insufficient: prescribe a graded plan starting with 20 minutes of vigorous activity (e.g., brisk walking, running, swimming) 3 days/week, increasing by 5–10 minutes weekly until reaching 60 minutes/day, 5 days/week. If sufficient: reinforce current regimen and encourage variety to maintain adherence.

## Clinical Guardrails / Mimics / Pitfalls
Do not prescribe high-impact activity in patients with uncontrolled hypertension, severe joint limitations, or recent concussion without medical clearance; avoid focusing solely on weight loss as outcome; ensure activities are enjoyable and developmentally appropriate to prevent dropout; do not substitute screen-based sedentary time with passive video-guided exercise without actual movement.

## Concrete Clinical Example
A 12-year-old with BMI at the 92nd percentile reports no regular vigorous activity. Prescribe: start with 20 minutes of brisk walking 3 days/week; add 5 minutes each week; goal: 60 minutes/day, 5 days/week (e.g., jogging, dance, sports) within 8 weeks.
