Vitamin A is an essential micronutrient for the normal functioning of the visual system, growth and development, immunity and reproduction. Its deficiency causes anemia, growth retardation and xerophthalmia. Vitamin A deficiency also increases the incidence and/or severity of infectious episodes and affects child survival. Reduced child survival is the most severe and potentially the most widespread consequence of Vitamin A deficiency. Improvement in vitamin A status is now regarded as one of the most cost effective preventive measures for the reduction of child mortality and morbidity.

Over the past decade several studies have examined the effect of vitamin A on reducing mortality among children aged ≥6months at the time of intervention. Impact of vitamin A supplementation can significantly reduce total mortality but it is only established through supplementation programs in children age 6 months or older. It was assumed that breast milk protects infants from vitamin A deficiency, but recent evidence has challenged this. Infants born with low stores of vitamin A and if the mother breast milk has a low concentration of vitamin A, as found in developing countries, the infants might be unable to meet their daily requirements and improve body reserves. There is association between mortality and degree of vitamin A deficiency, greater the degree of deficiency, higher the mortality.

The role of vitamin A in child survival is now well established and over 60 countries have vitamin A supplementation programs nationally. However, most are still using vitamin A supplements in the second half of infancy, even though over 75% of all under 5 deaths take place in the first 6 months of life. If neonatal vitamin A supplementation can be found to be effective and a service delivery mechanism also found, this will represent a major advance in reaching the MDG 4 targets. This is thus persuasive reason to explore this particular preventive strategy, especially in terms of packaging with other postnatal care activities. However, given that in some instances it has been difficult to disentangle the effect of vitamin A dosing from concomitant vaccinations such as BCG, the current evidence needs further evaluation in effectiveness settings. We propose to evaluate the effectiveness of early neonatal vitamin A administration (single dose 50,000 units) to the newborn to see its effect on infant mortality less than 6 months of age as part of postnatal package through National Program.

Government has launched the National Program for Family Planning and Primary Health Care since April 1994. Primarily it is being implemented in the community through Lady Health Workers (LHWs) of the National Program.

The LHWs are females, with a minimum of eight years of education, residents of the locality in which they are working. The Programme is being currently implemented in all the districts throughout the country and 93,000 LHWs are working covering primarily women and children of the rural population. These LHWs deliver services related to family planning, maternal and child health, immunization, nutrition and treatment of minor ailments to her average registered population of 100-150 households or ~1000 population. Over 3,000 Supervisors have been recruited and trained to supervise the work of LHWs.
