In fact, children are getting obese at an even faster rate.

2The recent increase in the rate of obesity around the world has been very shocking.

Doctors encourage everyone to understand their BMI and keep track of their weight and health.

1The most important reason for you to be aware of your BMI is so that you can assess your risk of being obese or underweight and prevent other health-related complications that come with it.

The BMI for age percentile ranking indicates the relative position of the child’s BMI number among children of the same gender and age. A BMI-for-age measurement can help you know better whether your child is at a healthy weight for their age, gender, and height. So, in children and teenagers, the healthy range of their BMI varies based on age, height, and weight.

In children and teenagers, it is perfectly normal to have varying amounts of body fat accumulation at different ages and for girls and boys to have different amounts of body fat. Understanding the children’s BMI can be very helpful in preventing childhood obesity. A child’s BMI can help determine whether your child is at a healthy weight or not. Children’s weight and height, according to their age, are important indicators of a child’s overall health and growth. The body fat location is significant because it could be a better indicator of risks for many diseases.īMI for children, also referred to as BMI-for-age, is gender and age-specific and can be used for two to twenty years old because girls and boys differ in body fat contents as they mature. Fat that gathers around the waist and chest proves to be more dangerous for long-term health than the accumulation of fat around your hips and thighs. Although, for precise measurement of an individual’s weight and health, a further medical examination should be commenced. Nonetheless, BMI does provide an indication of the effect of your weight on health and is extremely useful and accurate for the statistical measurement of health in large groups. That is to say, BMI is not beneficial to predict the accurate health of an individual, specifically when applied to individuals with abdominal obesity, unusually short or tall stature, high muscle mass such as in athletes, etc. However, everything constitutes a particular set of pros and cons, and therefore BMI calculator also has some limitations. It was later renamed as BMI calculator in 1972 by an American physiologist Ancel Keys, who studied the influence of diet on health. The Best Weight Loss Hospital in LahoreĪ Belgian mathematician, sociologist, astronomer, and statistician Lambert Adolphe Jacques Quetelet devised the basis of the BMI calculator between 18 at that time, it was known as the Quetelet index.© 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society. This study lends further support to the belief that the World Health Organization guidelines for BMI are overly restrictive in old age. Persons who increased or decreased in BMI had a greater mortality risk than those who had a stable BMI, particularly those aged 70 to 79. Old persons who were overweight had a lower mortality risk than old persons who were of normal weight, even after controlling for weight change and multimorbidity. That is, the higher mortality risks associated with BMI loss and gain were less severe in very old age. Age moderated the BMI change differences. 001) and 53% higher for the BMI gain group than for the BMI stable group (RR = 1.53, P =. Furthermore, mortality hazard was 65% higher for the BMI loss group than for the BMI stable group (RR = 1.65, P <. 603), independent of age, education, and multimorbidity. 011), and the mortality hazard for the obese group did not differ significantly from that of the normal-underweight group (RR = 0.93, P =. Mortality hazard was 20% lower for the overweight group than the normal-underweight group (relative risk (RR) = 0.80, P =.

Information about survival status and time of death was obtained from the Swedish Civil Registration System. Pooled data from three multidisciplinary prospective population-based studies: OCTO-twin, Gender, and NONA.Įight hundred eighty-two individuals aged 70 to 95.īMI was calculated from measured height and weight as kg/m(2). To examine how body mass index (BMI) and change in BMI are associated with mortality in old (70-79) and very old (≥80) individuals.
