Research has found that there are many factors that can affect a child's development negatively. Many of these are much more widespread in developing countries.Stunting due to malnutrition may reduce IQ (intelligence quotient) by 6-13 points and affects 25-30% of children. Iodine deficientcy may reduce IQ by 9-13 points and affects 35% of children. Iron deficiency anemia may reduce IQ by 1.73 IQ points/10 g/L hemoglobin (iron-containing oxygen-transport metalloprotein in the red blood cells.) Anemia affects 20-30% of children. Lack of stimulation/learning opportunities may reduce IQ by 0.5-1 SD (standard deviation) . 60-90% of children are not stimulated by parents. A number of other factors have also been associated with poor child development with varying degree of evidence: Maternal depression, exposure to violence ,intrauterine growth retardation (poor growth while baby is still in the womb) , malaria, lead,lack of breast feeding, loss of a parent, zinc deficiency, intestinal helminths (parasitic worms such as tapeworm and roundworm) , HIV, diarrhea, arsenic, and manganese and pesticides.

Child development is important so we have to take care of child and make good environment for them. We have to teach them good thing and habits. We have to provide good education that help to make them self dependent and for future development.

These are great facts to know. I didn't know that malnourishment and anemia could affect a child's IQ so much. This is something we can take care of in child cares but I fear for children in 3rd world countries. http://www.miniapplemontessori.com/prepare-your-child-for-the-future-with-preschool-montessori-learning-in-roseville-mn/
