Factors Affecting Height Development
The development of the length of the fetus is very early in the first weeks of pregnancy and the length reaches its peak before the 15th week of pregnancy. Whereas the fetal weight reaches its highest during the 32nd to 34th week of pregnancy.
Nutrition plays an important role in height development. After birth, in the first year the height of children grows quickly. The height of a 1-year-old child is one and a half times the height at birth, for example at birth, the length of a child is 50cm, and up to 1 year of age will be 75cm. From 1 to 10 year olds, children in the period of regular growth increase on average about 5cm.
When it comes to pre-puberty, children grow up very quickly. The age of pre-puberty for Vietnamese children is 9 - 11 years old for girls and 12 - 14 years old for men
At this age, the height of girls increases by 6cm and 7cm for men.
When puberty (12-13 for women and 15-16 for men), growth slows, increasing by about 2cm each year. The next stage until the age of 25, the growth is very slow, only increased by 1-2cm or almost no increase. The adult body is about 23 years old for women and 25 years for men.
Many studies show that there are many factors that affect height growth, but there are three main factors that can be affected: nutrition, social environment, exercise and exercise.
Environmental - social factors
Environmental and social factors have a great influence on the physical development of children, especially the height development.
Children are susceptible to stunting malnutrition when living in underdeveloped socio-economic conditions, unsanitary environment, not enough clean water, unsafe food and poor quality of care.
The role of protein (protein): protein plays an essential role in the structure of the body, especially animal proteins with all the necessary amino acids
The role of calcium: Calcium is the main nutrient involved in skeletal structure, calcium deficiency affects the strength and strength of bones.
The role of lipids (fat): very important in the development of long bones of children as a child. Fat also helps to enhance the absorption of oil-soluble vitamins such as vitamins A, D ... help the bone development.
The role of micronutrients: Recent studies show the effect of micronutrient deficiency on stunting malnutrition, especially notably the effects of zinc, iron, vitamin A and iodine deficiency.
Exercise and sports
Regular exercise and sports have a very good effect on the physical development and enhance the quick reflexes, endurance, toughness. Many sports support the development of height, such as swimming, high jump, running .
All interventions to improve the height of the person should be carried out early, as soon as possible right from the first weeks of the fetus. The process of nutrition and health care should continue to be carried out synchronously throughout the next process, from the time the child is born, the period of breastfeeding, the age of preschoolers, the age of pupils, adolescents.
Therefore, it has recently been recognized that a new approach is to take early nutritional care, care for girls from students, from adolescence to before pregnancy. At the same time, in the process of nurturing children need special attention to the key stages of height development, that is the fetus period, the first year of life and the period of pre-puberty. During these periods, the impact of nutritional factors has a positive effect on height development..
