Weight-for-age
Weight-for-age compares the child's body weight with the WHO reference population of the same age and sex. This indicator reflects body mass relative to age but does not distinguish between height and body composition.
The child is aged 71 completed months with a measured weight of 21.50 kg.
The plotted measurement corresponds to a weight-for-age z-score of 0.42 and a percentile of 66.4.
This indicates that the child's weight is approximately 0.42 standard deviations above the WHO reference median and exceeds the weight of approximately 66.4% of children of the same age and sex in the reference population.
This graph displays the child's anthropometric measurement in relation to the WHO Child Growth Standards (birth to 60 months) and WHO Reference 2007 (61 months to 19 years). The vertical reference line indicates the child's age. The horizontal reference line indicates the child's measured value. The plotted point represents the child's position relative to the WHO reference distribution for children of the same age and sex. The growth curves represent selected z-score reference values.
Length/Height-for-age
Length/height-for-age compares the child's attained stature with the WHO reference population of the same age and sex. This indicator reflects linear growth.
The child is aged 71 completed months with a measured height of 115.4 cm.
The plotted measurement corresponds to a length/height-for-age z-score of 0.06 and a percentile of 52.2.
This indicates that the child's height is approximately 0.06 standard deviations above the WHO reference median and exceeds the height of approximately 52.2% of children of the same age and sex in the reference population.
This graph displays the child's anthropometric measurement in relation to the WHO Child Growth Standards (birth to 60 months) and WHO Reference 2007 (61 months to 19 years). The vertical reference line indicates the child's age. The horizontal reference line indicates the child's measured value. The plotted point represents the child's position relative to the WHO reference distribution for children of the same age and sex. The growth curves represent selected z-score reference values.
BMI-for-age
BMI-for-age compares the child's body mass index with the WHO reference population of the same age and sex. BMI is calculated as weight in kilograms divided by height in metres squared.
The child has a BMI of 16.1 kg/m².
The plotted measurement corresponds to a bmi-for-age z-score of 0.53 and a percentile of 70.2.
This indicates that the child's BMI is approximately 0.53 standard deviations above the WHO reference median and exceeds the BMI of approximately 70.2% of children of the same age and sex in the reference population.
This graph displays the child's anthropometric measurement in relation to the WHO Child Growth Standards (birth to 60 months) and WHO Reference 2007 (61 months to 19 years). The vertical reference line indicates the child's age. The horizontal reference line indicates the child's measured value. The plotted point represents the child's position relative to the WHO reference distribution for children of the same age and sex. The growth curves represent selected z-score reference values.
Z-score reference curves
Green line: Median (0 SD). Gold lines: +1 SD and -1 SD. Red lines: +2 SD and -2 SD. Black lines: +3 SD and -3 SD.
A z-score expresses the distance between the child's measurement and the WHO reference median in units of standard deviation. A z-score of 0 corresponds to the WHO median. Positive z-scores indicate measurements above the median. Negative z-scores indicate measurements below the median.
Reference: WHO Child Growth Standards (0–5 yr) and WHO Growth Reference (5–19 yr). LMS values interpolated linearly between monthly points. This tool is for educational use; clinical decisions should rely on validated software.
