So health promotion was described as the process, which enables the people or individual to increase their control, over their health, and to improve their health. This conference provided the forum to discuss and establish the means and ways of working for health promotion and thence to develop the strategies of health promotion. In fact health promotion strategies and programs are needs based; they may be different for different countries because of the local needs as well as the unique cultural and economic systems (Ref- Ottawa, http://www.who.int/healthpromotion/en/). Actually, in this conference it was optimized that Health for All by 2000 (HFA 2000) could be possible through the successful implementation of health promotion strategies at national and regional levels (Ref).

Role of nutrition in learning and cognition starts even before the birth of child. If there is hypoplasia or deficiency of Iodine in the diet of pregnant woman, her newborn will be born with hypothyroidism. If the situation is not corrected with appropriate supplement along with regular feed even in early neonatal period the child cognition may be affected which in turn leads to all type of deficient learning, poor alertness and behavioral changes (Ref). The last trimester and some time beyond neonatal period (about two months) are critical because during these weeks the development of brain in its full swing and a greater part of this over all growth is completed by this time. Of course a simultaneous process of physical growth is also on progress (Ref). During this time the newborn is totally dependant on his / her mother's condition. Her health and nutrition status before conception, the chain of events during pregnancy, nutritional increments during pregnancy, and any acute but severe or prolonged illness, all have their own effect on the health of mother, the progress of pregnancy and eventually the status of fetus and pregnancy outcome. Once the newborn has started feeding, he or she again is dependant on the mother's health and nutrition status even if on breastfeeding or not. Because mother's role in the over all upbringing and growth of the newborn and further child in later period cannot be ignored.
