The growth rate skill helps to track the growth of infants, children, and adolescents. The child's age can range from 0-20 years. The growth charts consist of a series of percentile curves that illustrate the distribution of selected body measurements in children. Some use case scenarios for the skill is-
a) Helps parents find out how their child sizes up to other boys and girls of the same age b) Helps physicians track a child's growth and determine if the child is growing in a healthy way
As a user of this skill, you need to input the age and gender of the child, whose growth percentiles you need to calculate. And you will be taken into a conversation with the skill, which calculates the child's growth rate in regards to height, weight, head circumference and BMI in some cases. To input age and gender, the user can straight away specify them as "age is 25 months" and "Gender is male" when prompted. Please note that the skill accepts age in months.
The head circumference and BMI growth rate are provided based on selected age ranges, as per the CDC growth chart. If the age specified by user is eligible for both HC and BMI, we give both percentiles. On the other hand, if age range doesn't support BMI or HC, they will not be prompted for those inputs.
Currently, the skill accepts weight in pounds or kilograms based on the user selection. Consequently, the unit of height is either feet and inches or centimeters based on the unit of weight. For example, you can say weight is 67 kilograms or to say in pounds simply say weight is 155.3 pounds when prompted. Similarly, to say height simply say “5 feet 7 inches” or to say in centimeters, you can say, “159 centimeters”. As for head circumference you need to specify it in centimeters. Thus, you can say "Head circumference is 48 centimeters". Also, you need to say Yes or No when prompted to calculate your BMI growth percentile.
The 2000 CDC Growth Charts consist of a set of charts for infants, birth to 36 months of age and a set of charts for children and adolescents from ages 2 to 20 years. The charts for infants include sex-specific smoothed percentile curves for weight-for-age, recumbent length-for-age, head circumference-for-age, and weight-forrecumbent length; the charts for children and adolescents include weight-for-age, stature-for-age, and body mass index (BMI)-for-age curves. The BMI-for-age charts represent a new tool that can be used by health care providers for the early identification of children who are at risk for becoming overweight at older ages. The 2000 CDC Growth Charts also include weight-for-stature charts for statures ranging from 77 to 121 cm, primarily intended for use among children from ages 2 to 5 years.
Growth charts are not intended to be used as a sole diagnostic instrument. Instead, growth charts are tools that contribute to forming an overall clinical impression for the child being measured.
