What Is The Definition Of Obesity Quizlet
Obesity is defined as having a body mass index (BMI) at or above the 95th percentile for children and teens of the same age and sex. BMI is calculated by dividing weight in kilograms by the square of height in meters, and for children and teens, it is age- and sex-specific and referred to as BMI-for-age.
Obesity is characterized by having a BMI that falls in or above the 95th percentile for the individual's age and sex. BMI is computed by dividing weight in kilograms by the square of height in meters, and it is specific to age and sex for children and teenagers, known as BMI-for-age.
What is the difference between overweight and obesity?
Overweight and obesity refer to the abnormal accumulation of excessive fat that poses health risks. The BMI is used to determine if a person is overweight (BMI over 25) or obese (BMI over 30).
What is the difference between subcutaneous and visceral obesity?
Subcutaneous obesity refers to the accumulation of fat outside the body cavity, typically in the abdominal or gluteofemoral areas. In contrast, visceral obesity refers to the buildup of fat inside the body cavity, specifically in the omental and mesenteric areas. Obesity assessments include BMI, waist circumference, and body fat percentage. BMI is a measure of an adult's weight in relation to their height, and BMI values can be used to determine if an individual is underweight, normal weight, overweight, or obese.
What causes overweightness and obesity?
Overweightness and obesity stem from excessive calorie consumption and insufficient physical activity.
How do you categorize obesity?
Obesity can be quantitatively defined and categorized using methods such as the body mass index (BMI), which is a person's weight in kilograms divided by their height squared in meters.
Obesity is characterized as having a BMI at or above the 95th percentile for children and teens of the same age and sex. This means that individuals with such a BMI are considered to be in the obese category. For example, a 10-year-old boy who weighs 102 pounds and has an average height of 56 inches would be classified as having obesity as his BMI would fall in the 95th percentile.
What is the difference between obesity and overweight?
The difference between obesity and overweight is that obesity is characterized by a body mass index (BMI) at or above the 95th percentile, while overweight is defined as a BMI at or above the 85th percentile and below the 95th percentile. Severe obesity is indicated by a BMI at or above 120% of the 95th percentile.
What is the difference between a healthy and underweight BMI?
A healthy BMI falls between the 5th and 85th percentile, while an underweight BMI is below the 5th percentile.
How are obesity percentiles calculated?
The obesity percentiles for children and teens are calculated based on the CDC growth charts that were developed from national survey data collected between 1963 and 1994. Obesity is defined as having a BMI at or above the 95th percentile for children and teens of the same age and sex.
What is severe obesity?
Severe obesity occurs when a child's Body Mass Index (BMI) reaches the 120th percentile or is over 35. It is increasingly prevalent in children and has significant health consequences.
Belly fat can be classified into subcutaneous fat and visceral fat. Visceral fat is the unseen fat around organs, which is often called visceral abdominal fat. Even individuals who seem fit could have harmful visceral fat.
Subcutaneous vs Visceral fat. Which do you carry?
Subcutaneous fat is found under the skin and can be measured with calipers, while visceral fat is found in the abdominal cavity and is harder to measure.
What is the subcutaneous layer?
The subcutaneous layer is a skin layer located beneath the dermis, composed of fat cells, collagen, blood vessels, and nerves. Its functions include insulation, shock absorption, structural support, and energy storage.
What is the difference between subcutaneous intramuscular and intravenous injection?
The difference between subcutaneous, intramuscular, and intravenous injection is the site where the drug is delivered. Subcutaneous injection penetrates the subcutaneous tissue, intramuscular injection penetrates a muscle, and intravenous injection delivers the drug directly into a vein.
What is Obesity classification?
Obesity classification is the ranking of the medical condition in which excess body fat has accumulated to the extent that it has an adverse effect on health. The classification is based on the body mass index (BMI) and is established by the World Health Organization.
How is obesity defined and measured by the World Health Organization?
The World Health Organization defines and measures obesity based on the metric, body mass index (BMI), for both adults and children worldwide.
How are obesity & overweight diagnosed?
Obesity and overweight are diagnosed by calculating the body mass index (BMI), which compares a person's weight to their height. This is the most common method used to estimate body fat in individuals.
Overweight and obesity are both unhealthy conditions diagnosed by using BMI. Overweight is considered when the BMI is between 25 to 30, while obesity is diagnosed when the BMI is above 30. Overweight individuals have an increased risk of developing obesity, while obese individuals are at a higher risk of developing multiple diseases.
What is the definition of obesity in adults?
The World Health Organization defines overweight as having a BMI of 25 or higher and obesity as having a BMI of 30 or higher, providing a useful population-level measure for both sexes and all adult age groups.
What is the definition of overweight and obesity in children?
Overweight and obesity in children aged 5-19 are defined as being greater than 2 standard deviations above the WHO Growth Reference median.
Is a BMI of 30 considered obese?
Obesity is a medical condition characterized by excess body fat that can negatively affect health, with a BMI of 30 or higher considered obese. Overweight is defined by a BMI of 25-29.9.
