For a long time, height seems to be the standard for people to measure others, especially between the opposite sex. Women generally think that 175cm or more is regarded as "standard"; while men believe that women over 175cm will bring themselves a sense of oppression Thoughts.
On November 7, local time, a new study was published in the authoritative medical journal "The Lancet". Studies have shown that from 1985 to 2019, China and South Korea have become the countries with the fastest growth in average height of children and adolescents aged 5 to 19. Among them, the average height of 19-year-old men and women in China is 175.7cm and 163.5cm, which are 0.2cm and 0.3cm higher than South Korea respectively, ranking first in East Asia.
The countries with the highest average height of 19-year-old men and women are the Netherlands (male 183.8cm/female 170.4cm); the countries with the shortest average height of 19-year-old men and women are East Timor (male 160.1cm) and Guatemala (female 150.9 cm).
In the past 35 years, the average height of 19-year-old men in China has increased by 8cm, and the average height of women has increased by 6cm, ranking first and third in 200 countries and regions respectively.
The study compared the average height and average BMI of children born in 2000 in each country with the corresponding median WHO growth reference. The comparison found that in many countries/regions, the average height of the entire late childhood and adolescence was equal Lower than the median WHO growth reference.
It is well known that height is affected by genetic factors, but related studies of genetics have shown that the role of genetics will change over time. Compared with nutrition and the environment, genetics has little effect on people’s final height. This discovery is also supported by the fact that the height of the descendants of immigrants usually converges to the height of the new country within a few generations.
Now we will find that the height of children is generally higher than that of their parents, which also supports the above view: for height, genetics is not the decisive factor. Therefore, don't look up and wonder whether my child is holding the wrong question. Then why are young people taller than the older generation?
Throughout history, people of the older generation have suffered too much hard work and have many children at home. In order to survive, they generally took care of their home life when they were in school. It can be said that it was the earliest "part-time study", "a drop of sweat fell on the ground. In the days when they became eight petals, they often had no food and even suffered famine. With the gradual development of the times, today's children not only rarely suffer from food shortages, but even hard work is scarce. In contrast, we find that each generation seems to have increased in height relative to the previous generation.
The arrival of puberty sooner or later is affected by diet, physical activity and weight gain in childhood, and the timing of puberty further affects the peak growth of puberty and the height increase in the late puberty. Among the many factors affecting the growth and development of adolescents, nutrition is an extremely important factor. The development speed of various systems and organs is different at different ages. Men and women have their own rapid development stages. Strengthening the supply of nutrients during the critical period can maximize the growth and development potential.
Children who are growing rapidly need a lot of protein. Adults need about 80 grams of protein a day, while children need more. In terms of protein intake, we must not only ensure quality, but also pay attention to quality. For example, the essential amino acids contained in eggs, meat, fish, and milk are relatively complete and have high nutritional value. However, you should pay attention to the combination of meat and vegetables, and eat with vegetables and fruits.
Height and Body Mass Index (BMI) are indicators to measure the nutritional quality of childhood/adolescence and the health of the living environment. Through these two indicators, the health status and personal development results of a certain individual can be highly predicted.
Being too tall or too short (represented by low BMI) will increase the risk of morbidity and death, impair cognitive development, and reduce future educational performance and work efficiency; higher BMI is associated with disability and premature adulthood The higher risk of death and poor mental health are related to educational outcomes.
were included in Wiley OnlinThe two articles in the e Library and European Heart Journal are titled [The impact of childhood obesity on morbidity and mortality in adulthood] ("The impact of childhood obesity on adult morbidity and mortality"), [Short stature is associated with coronary heart disease ] ("Short Stature is Related to Coronary Heart Disease") academic journals also stated that there is an association between height and BMI and prevalence.
therefore provides high-level nutrition, maintains healthy living habits, and is in a high-quality living environment to ensure the healthy growth of children. And where are these good habits reflected? In addition to ensuring a healthy diet and eating less junk food, it should also be ensured that there are sufficient exercise opportunities and a positive and sunny mood during the growth and development of the child.
