The birth weight of a child is the first and most important indicator of his or her health condition. Birth weight is the first weight of the fetus obtained after birth. But this is the end result of a long process that takes place through maternal nutrition. Unless the baby is preterm (born before the end of the 3rd trimester), its average weight should be above 2,500 g to be considered normal (WHO, 2000). This is not only a risk for underdeveloped or developing countries, but also affecting developed countries. There are numerous factors that influence this adverse situation. In this document it will be discussed thoroughly and broadly with some logical solutions that would be ideal to introduce immediately. Regarding the above concerns, this problem of low birth weight (LBW) has caused many health problems in the latter part of life. This impairment of fetal nutrition and consequent intrauterine growth restriction have been the cause of infant mortality in 8-17% of pregnancies in developed and developing countries (UNICEF, 2003). Although the child is of low weight, he may have many health problems within the body which manifest themselves in the elderly period. To describe the prevalence of this low birth weight across the world, table 01 is given below. According to this table, South Asian countries have a high number of low birth weight. In the Sri Lankan situation it remained at a tolerable level at 18%, but should be reduced. Furthermore, compared to the universal average, it is a slightly higher value, so in conclusion there is a significant difference in the percentage of low birth weight in both more developed and less developed countries. According to surveys conducted by many organizations, maternal malnutrition is predominant low birth...... middle of paper ......strict diet with little fiber and should not interrupt breastfeeding. Frequent testing of the child's growth is very important to see if he is growing properly unless we have to give supplements. This screening is effective for LBW children. The previous strategies can be aimed at optimizing fetal growth. Campaigns for pregnant mothers and provision of necessary supplements such as folic acid, vitamin C, iron and calcium. This has been significantly encouraged especially in Sri Lanka since 2009 through trials conducted by Kandy Hospital (Wickramasinghe SC et al, 2010). Unlike developed countries, developing or underdeveloped countries have slightly less concern for nutritional improvement and follow vague mandatory criteria. For example, in the United States, food manufacturers have a rule of indicating the trans fat content of the product. But most other countries do not follow such processes.
