# How do you measure a baby’s mid arm circumference?

Contents

Mid-Upper Arm Circumference (MUAC) is the circumference of the left upper arm, measured at the mid-point between the tip of the shoulder and the tip of the elbow (olecranon process and the acromium). MUAC is used for the assessment of nutritional status.

## How is mid-arm circumference measured?

Figure 2: Measuring MUAC

To measure: Bend the left arm, find and mark with a pen the olecranon process and acromium. Mark the mid-point between these two marks. With the arm hanging straight down, wrap a MUAC tape around the arm at the midpoint mark.

## What is the normal mid-arm circumference?

[6] MUAC is a useful indicator of malnutrition that can be used in ill patients (normal MUAC >23 cm in males, >22 cm in females).

## Why is mid-arm circumference age independent?

Abstract. Mid-arm circumference (MAC) has been extensively used at 1-5 years of age as an age-independent indicator of protein-energy malnutrition (PEM). Its role below 12 months of age has not been studied adequately and a search for a clinically reliable cut-off point has not been systematically done.

## What age is Muac?

MUAC is a quick and simple way to determine whether or not a child is malnourished using a simple colored plastic strip. MUAC is suitable to use on children from the age of 12 months up to the age of 59 months. However, it can also be used for children over six months with length above 65 cm.

## How do you calculate BMI using arm circumference?

Ask subject to let arm hang loose and with tape measure, measure circumference of arm at the mid point. Do not pull the tape measure tight – it should just fit comfortably round the arm. If MUAC is less than 23.5 cm, BMI is likely to be less than 20 kg/m2 I.e. subject is likely to be underweight.

## What is the ideal arm size for a woman?

Busts 28 – 40 inches

Bust 28 38
Shoulder 4.5 5.25
Sleeve Length 17.5 18.5
Upper Arm 9 11.5
Wrist 6 6.5

## What is the normal mid arm circumference of child?

MUAC of between 125mm (12.5cm) and 135mm (13.5cm), YELLOW COLOUR, indicates that the child is at risk for acute malnutrition and should be counselled and followed-up for Growth Promotion and Monitoring (GPM). MUAC over 135mm (13.5cm), GREEN COLOUR, indicates that the child is well nourished.

## What is the normal chest circumference for a newborn?

The body of a normal newborn is essentially cylindrical; head circumference slightly exceeds that of the chest. For a term baby, the average circumference of the head is 33–35 cm (13–14 inches), and the average circumference of the chest is 30–33 cm (12–13 inches).

## What is mid arm muscle circumference?

Mid-arm muscle circumference (MAMC) is a bedside anthropometric measurement that estimates somatic protein reserve, an early indicator of nutritional depletion. This measurement is simple, non-invasive, objective and inexpensive to perform.

## Is arm circumference normally distributed?

Many statistical procedures are based on the assumption that the data used are normally distributed. … Results: The distribution of MUAC showed no departure from a normal distribution in 319 (37.7 %) distributions using the Shapiro-Wilk test.

## What are the 4 types of malnutrition?

There are 4 broad sub-forms of undernutrition: wasting, stunting, underweight, and deficiencies in vitamins and minerals. Undernutrition makes children in particular much more vulnerable to disease and death.

## What is Muac in pregnancy?

The mid-upper arm circumference (MUAC) has been used for many decades to assess malnutrition in children aged &lt;5 years. Several studies have also shown a strong correlation between MUAC and BMI in both pregnant and non-pregnant adult populations.

## How is wasting calculated?

Percentage of children aged < 5 years wasted = (number of children aged 0–59 months whose z-score falls below -2 standard deviations from the median weight-for-height of the WHO Child Growth Standards/total number of children aged 0–59 months who were measured) x 100.

Severe acute malnutrition is defined by very low weight-for-height/length (Z- score below -3 SD of the median WHO child growth standards), or a mid-upper arm circumference < 115 mm, or by the presence of nutritional oedema.
