Dietary intake of trace elements, minerals and vitamins among severely malnourished children and its interrelationship with nutritional status:A prospective study.

Dietary deficiency of trace elements, minerals and vitamins has been associated with severe malnutrition among young children. Although levels of severe malnutrition among children are high in developing countries, data on dietary intake of trace elements, minerals, vitamins and other nutrients by severely malnourished (SMN) children are limited. The present prospective study was conducted for a period of 12 months in order to assess the intake of trace elements, minerals, vitamins and other nutrients by SMN children and its possible interrelationship with their nutritional status. The nutritional status of 1643 children in the age group of 6 months to < 6 years, registered at 50 Anganwadi centres at district Alwar and Bharatpur in Rajasthan in India, was assessed using weight-for-age criteria. A total of 150 children were identified as severely malnourished. Mothers of 130 of the children consented to their children's participation in the study. At the end of 12 months, full data was available for 60 of the 130 SMN children. The nutritional status and intake of trace elements, minerals, vitamins and other nutrients of the 60 SMN children were analysed at monthly follow-up visits. Results revealed that there was an increase in the intake of trace elements, minerals and other nutrients during the follow-up period as compared to the baseline survey. However, in all of the follow-up visits, an overall deficient intake of all of the trace elements, minerals, vitamins and other nutrients was observed in the SMN children except for protein, calcium and magnesium. Out of 60 children, 35 moved to higher nutritional grades. It was found that the intake of trace elements, minerals, vitamin and macro-nutrients was higher among children whose nutritional status improved as compared with the group that remained in the severe malnutrition category. The present study highlights that the existence of multiple trace element and vitamin deficiencies in the diets of SMN children could play a role in the severe malnutrition of these children.
