Every year over twenty million infants are born with low birth weight worldwide. About 3.6 million infants die during the neonatal span. Two-thirds of those deaths exist in southern Asia and sub-Saharan africa. More than one-third of kid deaths are thought to be owing to maternal and child undernutrition. Deficiencies in micronutrients such as folic acid, iron and zinc and vitamins A, B6, B12, C, E and riboflavin are extremely prevailing and should occur concurrently among pregnant women. Micronutrient deficiencies result from meagre intake of meat, fruits and vegetables, and infections may also be a cause. In pregnant women, numerous micronutrient supplementations encourage approach for reducing inimical maternity outcomes through revised maternal nutritionary and immune standing.
The World Health Organization (WHO) presently recommends iron and folic acid supplementation to cut back the chance of iron deficiency anaemia among pregnant women. Considering several developing countries have already got systems in place for the delivery of iron and folic acid supplements, micronutrient supplements may well be provided at a very little extra price.
Many efficient trails analysis exploring the consequences of maternal multiple micronutrient supplementations are conducted with some limitations. Though some researchers have raised controversy that micronutrient supplementation could increase perinatal mortality, none of the preceding review articles has adequately addressed this issue. None has examined the potential sources of heterogeneousness within the result of supplementation on perinatal mortality.
In extension, most of the studies reviews addressing maternal nutrition and birth outcomes have reached the complication by investigating single nutrients in isolation. On one level, this is often necessary for an in-depth study of the advanced problems involved. However, nutrient deficiencies are typically found in low-Socio-economic populations, wherever additional possible to involve multiple rather than single deficiencies and studies that address and convey along the broader image of multiple nutrient intakes or deficiencies are lacking.
