What is a healthy weight for a 12 year old?

To tell whether a young adolescent has a healthy weight, it can help to know the average for their age and sex. The averages for 12-year-olds are 89 pounds, for males, and 92 pounds, for females. However, beyond biological sex, many other factors influence someone’s weight at this age, including their height, body composition, the onset of puberty, environmental factors, and underlying health issues.

Below, we explore the averages and the factors that affect them, using statistics from the Centers for Disease Control and Prevention (CDC). We also describe some health risks of having a weight that is significantly below or above average. Biological sex plays a role in weight, and in general, a 12-year-old female weighs slightly more than a male of the same age.

When discussing a child’s weight, a doctor may refer to a statistic that indicates the percentage of others who weigh less or more. For example, a child in the 35th percentile weighs more than 35% of children of the same age and sex. By the same token, they weight less than 65% of these peers.

New booster cushion regulations – A booster cushion doesn’t provide anything like the protection offered by a high-back booster, particularly for younger children. Reflecting this, new booster cushions launched after March 2017 will only be approved for children over 22kg (around 6 years) and more than 125cm tall.

Your child must use a child restraint appropriate to their age/weight. A booster cushion may be ‘appropriate’ for children over 15kg or children over 22kg and 125cm depending on when they were developed and approved for sale.

Any child seat/booster is better than none, however, even for the older child, a high back booster does provide more protection.9 February 2017

Average baby weight and length chart by month – In the United States, the average baby weighs just over 7 pounds at birth. Girls (at 7 pounds, 1 ounce/3.2 kg) are a bit smaller than boys (at 7 pounds 8 ounces/3.4 kg) on arrival. The average newborn is 19 1/2 inches (49.5 cm) long, with girls measuring 19.4 inches (49.2 cm) and boys measuring 19.7 inches (49.9 cm).

While most babies lose weight during the first few days of life, within a couple of weeks they’re back to their birth weight. Until 3 months old, most babies gain about an ounce each day. By 4 months old, most babies have doubled their birth weight, and by 1 year, most have tripled it. Most babies also grow about 10 inches (25 cm) by their first birthday.

How old will my child be at 25Kg?

Community Heartbeat Trust CHILDREN AND DEFIBS The role of using defibrillators on ‘children’ is confusing. Typically ‘children’ with respect to defibrillators refers to any person under 25Kg in weight, which typically means 7 years and under in the UK.

Cardiac arrest in this age group is very rare, typically about 10 per annum (in non ‘at risk’ children) in over 3.4 million children, and so should not drive any decision on the choice of equipment. The confusion arises as some adverts for defibrillators say ‘child-friendly’ or suggest higher incidences that occur in reality, as they include teenagers.

A ‘child’ of 29 Kg and aged 61/2 is actually an adult, in defibrillator terms.2/3 of all child 999 issues are Respiratory Arrest, not Cardiac Arrest. So what is meant by ‘child use’ for defibrillators?

• HOW DO DIFFERENT DEFIBRILLATORS ADDRESS USE ON CHILDREN UNDER 8 YEARS OLD?
• In simple terms, it’s like driving a car at night with full headlights (Adult settings). The approaching car will be dazzled unless you:
• 1) Keep your headlights at full setting, resulting in possible accidents or damage – Retain adult settings on the defibrillator

1. 2) Place filters over your headlights to dim the beam, so they appear dimmer but are still facing full on – Using Paediatric electrodes that reduce the energy via resistors in the electrodes or cables
2. 3) Reduce the energy going to the headlights, so they appear dimmer but are still facing full on – Use of a “Child-switch” to reduce the energy being delivered to the electrodes
3. 4) Recognise the approaching car, its position on the road, turn the beam away and reduce the energy (dip the lights) – Use of Paediatric protocols within the actual defibrillator itself

Different defibrillator models use different approaches. However, the gold standard would be to change the protocols so that the energy and waveforms being delivered to the child, are appropriate for the clinical situation (4), rather than just reduce the energy. Looking at the Department of Health height/weight charts, the 50th percentile (ie average) for 25Kg is around age 71/2 in the UK. Girls are slightly lower. Thus over half of the children are over 25Kg by the age of 8 years old. Thus the important aspect to consider is weight, not age. Most defibrillators can be used on children down to the age of 1 year old. However, the guideline from the UK Resuscitation Council is that if possible and under the 25Kg threshold, paediatric electrodes should be used to reduce the shock level. However, if there are no attenuation devices available, then adult electrodes can be used but placed front and back of the patient.

Many manufacturers now supply purpose-made paediatric pads or programmes, which typically attenuate the output of the machine to 50–75 J. These devices are recommended for children between 1 and 8 years. If no such system or manually adjustable machine is available, an unmodified adult AED may be used”.

“Pads should be placed front and back.” RC(UK) 2015 guidelines for paediatric life support In reality, this means that the chance of using a defibrillator on a child under the age of 8 years old in an average community in the UK is about 1 in 3000 years.

1. The chance of that defibrillator being used on an adult in the community (ie over 8 years old) is 1 in 1000 people per annum.
2. In simple terms, it is more likely to be used on the adult many times more than an under 8.
4. Switch’ devices generally can easily be left in a paediatric setting when not in use.

What size car seat? – Car seats are divided into 3 main groups, depending on your baby or child’s age and weight:

group 0+ – rear-facing car seats suitable for babies aged up to about 15 months or who weigh up to 13kg (29lb); some can be clipped on to a pushchair frame and are known as travel systems group 1 – rear or forward-facing seats suitable for children who weigh 9-18kg (20-40lb) or who are aged from about 9 months to 4 years group 2/3 – rear or forward-facing high-backed booster seats suitable for children who weigh 15-36kg (33lb-5st 9lb) or are aged from about 4 to 11 years

You can also buy combination seats that cross over these groups, such as group 0+/1 seats, which are suitable from birth until your child weighs about 18kg (40lb) or is aged about 4. Use a rear-facing car seat for as long as your child fits into it, as these offer better protection in the event of a car accident.

Is 40 kg overweight for a 10 year old?

BMI and BMI Categories for Children and Teens – Body mass index (BMI) is an anthropometric index of weight and height that is calculated by dividing a person’s weight (in kilograms) by the square of their height (in meters). Because children and teens are growing, the ranges of height, weight, and BMI vary by age and sex.

1. As a result, BMI values need to be expressed relative to other children of the same sex and age.
2. The CDC Growth Charts display sex-specific BMI-for-age percentile curves and can be used to monitor the growth of children and teens aged 2-19 years.
3. BMI categories for children and teens are based on sex- and age-specific BMI percentiles, whereas BMI categories for adults are based on BMI only.

Child BMI categories and their corresponding sex- and age-specific BMI percentiles are in the following table:

BMI-for-age weight status categories and the corresponding percentiles

BMI Category BMI Range
Underweight Less than the 5 th percentile
Healthy Weight 5 th percentile to less than the 85 th percentile
Overweight 85 th percentile to less than the 95 th percentile
Obesity 95 th percentile or greater
Severe Obesity 120% of the 95 th percentile or greater OR 35 kg/m 2 or greater

For example, a 10-year-old boy who is 54.5 inches tall (50 th percentile for height) and weighs 96 pounds would have a BMI of 22.5 kg/m 2, placing him at the 96 th percentile for his age and sex, which is in the obesity category. This means that the boy’s BMI is greater than the BMIs of 96% of 10-year-old boys in the reference population.

Class 2 Obesity : BMI ≥120% to <140% of the 95 th percentile or BMI ≥35 to <40 kg/m 2 Class 3 Obesity : BMI ≥140% of the 95 th percentile or BMI ≥40 kg/m 2

For example, a 15-year-old girl who is 63.7 inches tall (50 th percentile for height) and weighs 210 pounds would have a BMI of 36.4 kg/m 2, placing her at the 99 th percentile for her age and sex. Her BMI is 129% of the 95 th percentile, which is class 2 obesity based on the expanded definition of severe obesity.
