Adapted by the State of California CHDP Nutrition Subcommittee from materials developed by California Department of Health Care Services Children’s Medical Services Branch Centers for Disease Control and Prevention Maternal and Child Health Bureau July 2013
Training Objectives
By the end of this presentation, you will be able to: • Select appropriate growth chart for age group • Identify the age range for which
Body Mass Index (BMI) screening is used • Calculate or determine BMI value • Plot BMI value on the appropriate growth chart • Determine BMI-for-age percentile • Identify weight category • Record results on PM 160
Which Growth Chart Should I Use?
• Birth to 2? Use WHO • 2 to 20? Use CDC
What Is Body Mass Index?
• A number calculated using weight and height measurements: Body Mass Index (BMI) = Weight (kg) / Height (m)²
• It compares a person’s weight to height
• It is an indirect screening test for body fatness
Why Use BMI-for-Age?
• Lifetime tracking tool
− from age 2 through adult
• Relates weight, stature and age • Screening for health and nutrition status
required by CHDP and health plans • Early indicator of other health risk factors
– Hyperlipidemia – Elevated insulin – High blood pressure
Body Mass Index Cutoff Values for Adults
• Standard weight categories • Same for all ages 18 + • Same for men and women
Weight Status Obese
Overweight Normal
Underweight
BMI 30.0 and above
25.0 - 29.9 18.5 - 24.9 Below 18.5
For Children, BMI Changes with Age
Example: Child’s growth tracking along 95th percentile
Age
2
4
9
13
BMI Value 19.3 17.8 21.0 25.1
BMI for Children and Teens
• Age- and sex-specific • Plot BMI to find percentile • Determine weight status
Weight Status Category Obese
Overweight Normal
Underweight
Percentile Range ≥ 95th percentile 85th to < 95th percentile 5th to < 85th percentile < 5th percentile
What is a Percentile?
