High hemoglobin in children - the dangerous deviation from the norm

March 7, 2012

 high hemoglobin children
 The hemoglobin level indicates any standard blood test. To understand what a high hemoglobin level, you must first know what is the norm. Hemoglobin levels in children varies depending on age. This indicator helps to diagnose the overall health of the circulatory system. The level of hemoglobin in the blood is measured in grams / deciliter (g / dL). The rate for children is as follows:

  • Newborns: 17-22 g / dl
  • Children aged 1 week: 15-20 g / dl
  • Children aged 1 month: 11-15 g / dl
  • Older children: 11-13 g / dl

According to studies, children born with high levels of hemoglobin and subsequently receiving infant formula fortified with iron, long-term development results were worse than children whose hemoglobin level was lower than originally.

Ten-year studies of the development of children showed that a six-month high hemoglobin children receiving iron-fortified infant formula, the development is slower.

In recent years, products enriched with iron, has established itself as an effective tool for iron deficiency anemia, as well as other forms of iron deficiency in infants. But what is the optimal iron content, particularly in the dairy mixture Dairy mixture - selection of useful power  Dairy mixture - selection of useful power
 , not yet known. In addition, the results of research carried out earlier and related iron deficiency and speed the development of newborns, were contradictory.

 High hemoglobin in children - the dangerous deviation from the norm


The present study is a continuation of a randomized controlled trial conducted in Chile, in Santiago, from 1991 to 1994. The six-month children randomly assigned infant formula fortified with iron (on average 12, 7 mg / l), or a mixture of containing a small amount of iron (on average 2 to 3 mg / l).

The primary study involved healthy full-term babies born in public hospitals, and 835 of them passed the test to the end. At the age of 10 years, 473 subjects (56, 6%) were subjected to research. Of these, 244 (56, 7%) were originally in the group receiving the mixture in a high iron content, and 229 (56, 5%) - group in which the mixture was allowed to reduced iron. A study conducted at the age of ten, involves testing the level of intelligence (Wechsler intelligence test for children), spatial memory, arithmetic ability, visual-motor integration, visual perception and motor functions.

As compared with the group receiving the mixture from the reduced amount of the iron group, which gave a mixture enriched with iron, showed lower results in all respects. At the same time the worst results relate to the spatial memory and visual-motor integration. The researchers say that these results showed suggestive trends in IQ, aptitude for arithmetic, visual perception and motor coordination (1, 4-4, 6 points below the magnitude of the effect, 0, 13-0.21).

Children who at the age of six months was observed a high level of hemoglobin (more than 12 8 g / dL) according to the parameters had lower results if they had previously received a mixture enriched with iron (10, 7-19, 3 points below the high value of the effect of 0, 85-1, 36).

Children with low hemoglobin aged six months (at least 10, 5 g / dl) was removed from the study conducted some benefit (2, 6-4, 5 points higher). The effect of this was a small but significant.

At 5, 5% of the subjects had revealed a high level of hemoglobin (n = 26), 18, 4% showed low hemoglobin levels (n = 87).

According to scientists, in the course of a decade of research involving children, there were no statistically significant differences in iron content between the two groups, with only one child discovered iron-deficiency anemia. Nine infants from the group receiving the mixture with a low content of iron, and 17 of the group receiving the iron-enriched mixture meets the criteria of iron deficiency.

One possible explanation for slow development of children with high levels of hemoglobin, by assumption, scholars, is that the food additive Food additives - basic classification  Food additives - basic classification
   could have an adverse effect on the development of their nervous system. However, in their opinion, this explanation assumes that the children involved in the study and have a high level of hemoglobin in infancy had a deficit of iron.

The main limitation of the study was attended by a small number of children with elevated levels of hemoglobin as possible. In addition, before randomization, hemoglobin level was the only way to determine the iron content of all infants.

In the case of reproducing this study require an analysis to determine the level of hemoglobin and / or other indicators of body iron content in early childhood before infants will produce iron-enriched mixture. In addition, it is necessary to revise the recommendations relating to the reception of universal iron supplementation. A group of scientists came to the conclusion that to determine the optimal level of iron in infant formula is required to conduct additional studies.

The relationship between iron deficiency, iron deficiency anemia Iron deficiency anemia: how dangerous it is?  Iron deficiency anemia: how dangerous it is?
   and development, remains controversial.

For example, further research conducted in Thailand, during which a period of six months to infants (ages four to six months) daily was given iron (10 mg), zinc (10 mg) and food supplements enriched in iron and zinc, nine years It did not reveal any differences in general, including the development and verbal IQ, compared with the development of infants receiving placebo Placebo - an effective tool for self-hypnosis  Placebo - an effective tool for self-hypnosis

While this is the only evidence of a negative impact on the development of children with high levels of hemoglobin, if we consider the group of children receiving early childhood mixture enriched with iron, and a group receiving a mixture with low iron content.

Gases in the newborn: follow certain rules

 gases newborns
 Gases in the newborn - is a common problem and does not threaten the health of the baby, but quite unpleasant for parents: little children become moody and restless, and young mothers often spend sleepless nights trying to calm babies. However, the problem of excessive emissions simply decide not even going to the doctor, and only following a few basic rules.

 Gases in the newborn: follow certain rules


Gaza - absolutely natural byproduct of the digestive process; problem is the excessive formation of gases that violates the proper functioning of the digestive system of infants. In this case, the gas accumulating in the intestine causes sharp pain in the abdomen Abdominal pain: Types and Symptoms  Abdominal pain: Types and Symptoms

  • Mother's diet: the diet, which adheres to the mother of a newborn baby - one of the key factors influencing the emergence of problems with gas in children. Dietitians and nutrition experts believe that a diet with a high content of dairy products, acid-forming foods and gas forming foods - such as legumes - can cause excessive production of gas in newborns, feeding breast milk.
  • Swallows air: newborn babies during breast swallow air, causing the later baby belly starts to become swollen. This problem may occur as breastfeeding Breast-feeding: feed - and no nails!  Breast-feeding: feed - and no nails!
 And artificial feeding when poorly chosen feeding bottles.
  • Crying: regular lament is absolutely normal for newborns, but prolonged crying sometimes leads to "swallow" the air, which in turn causes a problem with the gases.

How to understand that the newborn baby suffering from gas?

The main symptoms of this disorder is considered part of belching Belching: why it happens and that means  Belching: why it happens and that means
 , Bloating, diarrhea, constipation, or vice versa Constipation - Watch out for food  Constipation - Watch out for food
 Pain or abdominal cramps.

 Gases in the newborn: follow certain rules


The digestive system of newborn babies is still underdeveloped, to produce all the necessary digestive enzymes to fully and independently deal with excess gas. That's why the solution of this problem for you mother.

  • Help your child to vomit during or after feeding, to get rid of excess gases.
  • If the child is breast-fed, breast-feeding should take care of their diet and excluded from receiving any food products that cause the gases in the child - even by trial and error.
  • Lower the volume and increase the frequency of feedings. The large volume of milk at one feeding can cause digestive disorders and excess gas at the kid.
  • When artificial feeding is necessary to choose the right bottle for the baby.
  • Warm baths and gentle massage of children's stomach - proven and effective ways to alleviate the problem with excess gas in the newborn.

If the simple methods do not help deal with the problem of excess gas, you can use special medication to reduce the amount of gas produced in the newborn. Such preparations contain the active ingredient simethicone reduces gas and facilitates the withdrawal of gases. It must be remembered that the drugs do not prevent the formation of gas, but facilitate their conclusion.

Furthermore, such formulations are considered safe for infants as simethicone is not absorbed into the blood and does not contain alcohols.
