Because children and teens are growing, BMI values must be expressed relative to other children of the same sex and age. BMI-for-age percentiles indicate how your child's BMI compares to BMIs of children of the same sex and age in the reference population used to create the CDC growth charts.

Having severe obesity can increase a child or teen's risk for physical health conditions, including type 2 diabetes and high cholesterol, and mental health conditions, including anxiety and depression. Children with severe obesity are also more likely to have obesity or severe obesity in adulthood, which is associated with additional chronic health conditions, including cardiovascular disease, joint problems, and many types of cancer.

This BMI calculator is not meant to serve as a source of clinical guidance. It is not intended to be a substitute for professional medical advice.

Healthcare providers can assess height, weight, and BMI percentile at least annually for all children to help monitor growth relative to other children of the same age and sex. Healthcare providers can also assess for social and health risk factors, such as food insecurity and family history, and work with the patient and family on an individual plan to maintain a healthy weight and help prevent chronic conditions. identify supports and treatment options.

Based on the information entered, the body mass index (BMI) is 0. This child's BMI-for-age is ataboveless than the 0th percentile, which means that this child's BMI is lessgreater than the BMIs of 0% of 0-year-old s in the reference population used to create CDC's growth charts. This child's BMI falls into the category, defined as a BMI that is less than the 5th percentileat or above the 5th to less than the 85th percentileat or above the 85th to less than the 95th percentileat or above the 95th percentileat or above 120% of the 95th percentile for sex and age or a BMI that is at or above 35 kg/m2.

This calculator provides body mass index (BMI) and the corresponding BMI-for-age percentile based on CDC growth charts for children and teens ages 2 through 19 years. Because of possible rounding errors in age, weight, and height, the results from this calculator may differ slightly from BMI-for-age percentiles calculated by other programs.

BMI is one potential health indicator and should be considered with other factors when assessing an individual's health. These factors may include a patient's medical history, health behaviors, physical exam findings, and laboratory findings. Read more About BMI. Persons may consider seeking advice from their health care providers about their BMI. This calculator is not a substitute for professional medical advice.

BMI is a calculated measure of weight relative to height. BMI is used to assess a child's physical growth.

This calculator generates the BMI, BMI percentile, and BMI category for children and teens 2 through 19. The calculator also plots the BMI percentile on a growth chart and explains the results. Because of possible differences in rounding for age, weight, and height, the results from this calculator may differ slightly from other program results.

Recommended treatment might include referral to a Family Healthy Weight Program. These are comprehensive, family-based lifestyle change programs that help children and adolescents with overweight or obesity make progress towards a healthier weight through positive behavior changes.

Body mass index (BMI) calculators are screening tools to estimate weight status. Too much or too little weight can be a health risk.

Body mass index (BMI) is a measure of weight relative to height. For children and teens, BMI is interpreted using sex-specific BMI-for-age percentiles. This calculator reports BMI, BMI percentile, and BMI category for children and teens 2 through 19.

Circularly polarized light is rare in nature. It occurs only at total reflection of underwater linearly polarized light from the water-air interface outside the Snell window, at the reflection of light from the exoskeleton of certain insects and crustaceans, as well as in the bioluminescent light emitted by firefly larvae. Dinoflagellates are also known to induce circular polarization of light passing through their bodies (cf. Shashar et al. 1995a). However, optical structures which could selectively absorb and/or reflect left- or right-handed circularly polarized light have not been discovered until now in animal dioptric apparatuses. Furthermore, the photoreceptors do not discriminate between left- and right-handed circularly polarized light. Animals perceive circularly polarized light as if it was unpolarized, while elliptically and partially linearly polarized light with the same degree and angle of polarization cannot be discriminated by them. Thus, it is questionable whether circular/elliptical polarization of light in nature could have any biological importance.
