What is the normal height and weight of a 19 year old.

Human body weight measurement standards.

1. Weight. 1) Significance: Weight is the simplest, most direct and reliable indicator of nutritional assessment.

It has been used for a long time and is still the most important nutritional assessment index. Body weight is the sum of adipose tissue, lean tissue and minerals, and the change of body weight is parallel to the change of the balance of energy and protein in the body, so body weight can reflect the overall nutritional status of the human body.

2) Measurement method: The measurement of body weight must be consistent in time, clothing, posture, etc., and the inpatients should choose to get up in the morning on an empty stomach, empty and defecate, and wear underwear for measurement. The inductance of the scale shall not be greater than that, and it must be calibrated accurately before measurement.

3) Weight evaluation index:

Realistic weight is better than ideal weight Realistic weight Ideal weight 100

The evaluation of the results is shown in Table 2.

Table 2 Actual body weight as % of ideal body weight.

Results Weight status.

80% wasting.

80%-90% are on the light side.

90% to 110% normal.

110%-120% are overweight.

120% obese.

Weight change: Since there is no unified standard weight value in China, and the individual variation of height and weight is large, it seems more reasonable to use weight change as an indicator. It is expressed by the formula as:

Change in body weight (%) = [usual weight (kg) measured weight (kg)] Usual weight (kg) 100

The magnitude of weight change should be considered in conjunction with the velocity, and the evaluation criteria are shown in Table 3.

Table 3 Evaluation criteria for weight change.

Time Moderate weight loss Severe weight loss.

1 week 1 2 > 2

January 5 > 5

March >

June 10 > 10

Body mass index (BMI): BMI = weight (kg) Height (m2). BMI is considered a reliable indicator of protein, caloric malnutrition, and obesity. The BMI evaluation criteria are shown in Table 4.

Table 4: BMI evaluation criteria (WHO criteria).

Grade BMI value.

Obesity grade III >40

Obesity grade II 30-40

Obesity grade I. Normal value 18 BMI<25

Protein-caloric malnutrition grade I.

Protein-caloric malnutrition grade II.

Protein-caloric malnutrition grade III <16

Then it must be the height and weight of a 19-year-old.

Body mass index: 19 or less Low body weight.

19-25 healthy weight.

25-30 overweight.

30-39 severely overweight.

40 and above Extremely overweight.

Body mass index (BMI) is a reference index for assessing the ratio of weight to height.

It is calculated as body weight (kg) divided by height (m) squared (BMI = kg m2).

BMI (Body Mass Index) is an indicator closely related to the total amount of body fat, mainly reflecting systemic overweight and obesity. Since BMI calculates the proportion of body fat, it is more accurate in measuring the risk of heart disease and high blood pressure due to overweight than simply by weight. In particular, it is important to note that BMI is not applicable to everyone, and if you fall under the following conditions, then the BMI index is not applicable to you:

1.Under the age of 18.

2.It's an athlete.

3.Doing weight training.

4.Pregnant or breastfeeding.

5.Elderly people who are frail or sedentary.

The weight calculation formula of people commonly used in the world, as well as the calculation of body proportion (more suitable for Orientals) standard weight = (height cm-100).

Weight = (height cm-100).

Positive lack of evoked constant weight: standard weight -(how much) 10 exceeded. Heavy:

Weight greater than standard 10 Less than standard body weight 20 Mild obesity: greater than standard weight 20 Less than standard weight loss 30 Moderate obesity: greater than standard weight 30 Less than standard weight 50 Severe obesity:

More than 50 of the standard body weight.

Standard body fat: body mass index BMI = weight (kg) {height * height (m) ideal sign calculation method: (height height - 70) * unit: kg].

The formula for calculating people's weight commonly used in the world, as well as the calculation of body proportions, female] standard weight (female) = (height cm-100) normal weight: standard weight - (how much) 10

Overweight: greater than the standard weight 10 less than the standard weight 20 mild obesity: greater than the standard weight 20 less than the standard weight 30 moderate obesity: greater than the standard weight 30 less than the standard weight 50 severe obesity: greater than the standard weight 50 or more.

Male] standard weight = height (cm) - 105 + -5 minus 100 for height less than 165 cm minus 105 for height between 165 - 175 minus 110 for height higher than 175 weight for more than 10% of standard weight for overweight, more than 20% for obesity, less than 10% for normal, less than 10% for light, less than 20% for malnutrition.

Answer: At the age of 19, the height has basically been set, the standard height for this age group is, height is normal in this range, if the height is lower than the shorter height, if the height is greater than the higher height.

The standard weight of a 19-year-old girl is about the normal range, so in order to have a good figure, you must not keep thin, you just need to keep it in the standard range, which is the most beautiful.

Standard weight (kg) = height (cm) - 105. The standard height weight of 1.58 meters should be 53 kg, and those who exceed 10% of the standard weight are overweight, and those who exceed 20% are obese; Those who are less than 10% of the standard body weight are thin, and those who are less than 20% or more are emaciated. Being too fat and too thin is not good for your health and does not give you a sense of fitness.

Weight is proportional to height.
