Standard: FCS-FNW-1Students will discuss basic nutrient requirements and their use in dietary planning.

Element “C”Define a calorie, compare energy sources, compute Basal Metabolic Rate, Body Mass Index, and waist to hip ratio; apply outcomes to dietary planning and selection of nutrient dense foods.

How to Use Growth Charts & Anthropometric Measures:

Basal Metabolic Rate, Body Mass Index, Waist-to-Hip Ratio

Presentation by Rhonda L. Barlow; source: CDC.gov

Training Objectives

At the end of this presentation, you will be able to:

1. Discuss the history of the current CDC Growth Charts,

2. Select the appropriate CDC Growth Chart (Grid) needed based on the age and gender of the person,

3. Use the CDC Growth Charts to plot anthropometric measures,

4. Interpret the data plotted to assess physical growth.

History

Released = May 2000Developed by

National Center for Health Statistics (NCHS)Distributed by

Centers for Disease Control and Prevention (CDC)

Used for all children 2 to 20 years of ageScreening Tool

Assess physical growth/nutritional status Assess risk of underweight/overweight

Why Revise 1977 NCHS Charts?

Reference Population

Racially/Ethnically Diverse

Infants: Birth to 36 months

Children and Adolescents: 2 to 20 years

Breast- and formula-fed infants

Use and Interpretation of Charts

Step 1 = Obtain accurate weight and measures.

Step 2 = Select appropriate growth chart.Step 3 = Record anthropometric data.Step 4 = Calculate Body Mass Index (BMI).Step 5 = Plot measurements.Step 6 = Interpret plotted measurements.

As listed in “Use & Interpretation of the CDC Growth Charts,”

Accurate Weight and Measures

Calibrate height and weight equipment. Take off excess clothes and shoesCDC Recommended Protocol

Staturehttp://www.cdc.gov/nccdphp/dnpa/bmi/meas-

height.htm Weighthttp://www.cdc.gov/nccdphp/dnpa/bmi/meas-

weight.htm

Measuring Stature

Stand against stadiometer.

Feet, bottom, shoulders and head against wall.

Head straight.Bring measuring tool

level with head.Read height.

Measuring Weight

“Zero” out scale.Stand on scale.Hands and arms

straight down by side.

Waite for balance to record weight.

Read weight.

Measuring Waist

Use sturdy/un-stretched measuring tape.

Minimal/thin clothingMeasure around

smallest area or near navel.

Read measuring tape.Record data.

Measuring Hip

Use sturdy/un-stretched measuring tape.

Minimal/thin clothingMeasure around

largest area of bottom.Read measuring tape.Record data.

Select Appropriate Growth Chart

Record Data

Student’s nameRecord number = birth dateMother’s/Father’s Stature = optionalDate = day measurements takenAge = years, months, daysWeight = poundsStature = inchesBMI = manual calculationComments = any notable occurrence/observation

BMI Calculation Formula

Metric SystemBMI = weight (kg)/[stature (cm)]2 x 10,000

{OR}English SystemBMI = weight (lb) ÷ [stature (in)]2 x 703

Calculate as a continuous equation.

Calculation Practice

Sam’s anthropometric measuresweight = 37 pounds, 4 ouncesheight = 41½ inches

Convert ounces and fractions to decimals.

Answer37.25lbs ÷ 41.5 ÷ 41.5 x 703 = 15.2

Calculation Practice

Complete Your Growth Chart

Fill in name, birth date in “Record #”

Today’s dateAge = pretend you are 18,

19, or 20Record estimated weight

and heightCalculate your BMI based

on above.

Decimal Conversions Table

Plot Measurements

Find your age on horizontal axis.Years = 3 months incrementsFind appropriate measurement on vertical

axis. (Weight, length, stature, head circumference, BMI)

Make a small dot where the two lines intersect.

Visual Example of Plot

Interpret Plotted Measurements

1. Determine the percentile rank. 2. Determine if the percentile rank suggests that

the anthropometric index is indicative of nutritional risk based on the percentile cutoff value.

3. Compare today’s percentile rank with the rank from previous visits to identify any major shifts in the child’s growth pattern and the need for further assessment.

4. Anthropometric Index Percentile Cut-off Value Nutritional Status Indicator

Percentile Rank Indicated Nutrition- Related Health Concern

Anthropometric Index Percentile Cut-off Value

Nutritional Status Indicator

BMI-for-Age ≥ 95th Overweight

Weight-for-Length > 95th Overweight

BMI-for-Age ≥ 85th and < 95th At Risk of Overweight

Weight-for-Length < 5th Underweight

Stature/Length-for-Age < 5th Short Stature

Head Circumference-for-Age < 5th and > 95th Developmental Problems
