Adolescent obesity

Introduction Adolescent obesity refers to the phenomenon that excessive accumulation of fat in adolescents causes excessive body weight. In adolescent obesity, 10% of overweight is overweight, 20% is mildly obese, 30% is moderately obese, and 50% is severely obese. Adolescent obesity refers to the phenomenon that excessive accumulation of fat in adolescents causes excessive body weight. In adolescent obesity, 10% of overweight is overweight, 20% is mildly obese, 30% is moderately obese, and 50% is severely obese.

Cause

Adolescence is a stage in which female reproductive system development tends to mature. From the perspective of menstruation as an indicator of ovarian function, adult obesity is associated with menstrual abnormalities, while adolescents with high obesity have an early stage. The amount of body fat is closely related to menarche, and there must be a certain amount of body fat in the menarche period. Some scholars have conducted a survey of 24,115 middle school students and high school students, and found that the body fat of 9-15 years old, the body fat accounted for 21% to 24% of body weight; on the contrary, the future menstruation of people over 12 years old, the body fat is lower than the tide .

Obesity = (actual weight - standard weight) ÷ standard weight × ± 100%

10% overweight is overweight, 20% is mildly obese, 30% is moderately obese, and 50% is severely obese.

A person's body weight exceeds the standard state called obesity. So what is the standard weight? The standard weight is also called the ideal weight, which is based on the relationship between the height and weight of most people. The standard weights of different races and regions are also different. Such as the Japanese standard weight (kg) = height (cm) -105.

On the basis of a large-scale survey, the Chinese Academy of Military Medical Sciences conducts a formula for calculating the standard weight of the Chinese people:

Southern standard weight = (height (cm) -150) × 0.6 + 48

Northern standard weight = (height (cm) -150) × 0.6 + 50

The division between the north and the south is bounded by the Yangtze River.

Example: A ×, Tianjin person, height 173 cm. This person's standard weight = (173-150) × 0.6 + 50) = 63.8 kg

Fertilization and thinness assessment

Obesity can be calculated with standard weight.

Obesity = (actual weight - standard weight) ÷ standard weight × ± 100%

The degree of obesity is within ±10%, which is called normal moderate.

Obesity is more than 10% and is called overweight.

Obesity is more than 20%-30%, which is called mild obesity.

Obesity is more than 30%-50% and is called moderate obesity.

Obesity is more than 50%, and it is called severe obesity.

Obesity is less than 10%, which is called lean.

Obesity is less than 20%, which is called weight loss.

Differential diagnosis

Differential diagnosis of adolescent obesity:

First, simple obesity

1. Constitutional obesity

Reason: Congenital. The metabolism of substances in the body is slow, and the rate of synthesis of matter is greater than the rate of decomposition.

Phenomenon: The fat cells are large and numerous, all over the body, and there is baby fat on the face.

2, acquired obesity

Cause: Caused by excessive diet. Sweet food, greasy food, and fat are distributed in the torso.

Phenomenon: fat cells are large, but the number does not increase. Puffy physique, a pinch of meat, not tight.

Second, pathological obesity

1, Cushing Syndrome

Cause: Adrenal hyperfunction, excessive secretion of cortisol.

Phenomenon: The face, neck and body are hypertrophy, but the limbs are not fat.

2, pancreatic origin

Cause: Excessive insulin secretion, decreased metabolic rate, decreased fat decomposition and increased synthesis.

Phenomenon: generalized obesity.

3, sexual function reduction

Cause: Cerebral obesity, accompanied by loss of sexual function, or loss of libido.

Phenomenon: breast, lower abdomen, obesity near the genitals.

4, pituitary

Cause: Pituitary lesions cause excessive growth hormone secretion in the anterior pituitary.

Phenomenon: whole body bones, soft tissue, visceral tissue hyperplasia and hypertrophy. The bones are large and the stomach muscles are prominent.

5, hypothyroidism

Cause: Hypothyroidism.

Phenomenon: obesity and mucinous edema. The legs are often prone to edema.

6, drug-induced

Cause: Caused by side effects of the drug, such as caused by adrenocortical hormone drugs.

Phenomenon: Obesity that occurs after a period of medication, such as some patients with allergic diseases, rheumatoid diseases, and asthma.

7, subcutaneous obesity

Features: Fat is mainly distributed in the subcutaneous tissue of the abdomen, buttocks and thighs.

8, visceral fat

Characteristics: Fat is mainly distributed in the peritoneum in the abdominal cavity. There are a lot of meat on the waist and belly.

Obesity = (actual weight - standard weight) ÷ standard weight × ± 100%

10% overweight is overweight, 20% is mildly obese, 30% is moderately obese, and 50% is severely obese.
