Brief summary

The study entitled 'Effect of maternal hemoglobin on neurobehavioral development of late preterm neonates' was done with an objective to determine whether low maternal hemoglobin (\<11gm/dl), in late preterm neonates(\>34weeks but less than 37weeks gestational age) correlates with poor neurobehavioral outcome using the Neurobehavioral Assessment of Preterm Infants(NAPI) tool, thereby allowing for earlier rehabilitative intervention to be undertaken to improve their long term outcomes and to generate useful data on a previously well recognised but under researched entity.

Detailed description

Prevalence of anemia in India is among the highest in the world. A high proportion of women in both industrialized and developing countries become anemic during pregnancy. The major concern about the adverse effects of anemia on pregnant women and their offsprings is the belief that this population is at a greater risk of perinatal mortality and morbidity. Apart from this, it is well known that anemia per se is associated with higher incidence of premature births and low birth weight babies. Infants with iron deficiency anemia have significantly lower motor and mental scores and decreased language capabilities and body balance-coordination skills. Such infants also have a decreased learning ability. Iron deficiency anemia during the developmental stage can lead to reduced myelination of the spinal cord, as well as a change in myelin composition; abnormalities in neurotransmitters' metabolism and alteration in brain energy metabolism. The Neurobehavioral Assessments of Preterm Infants (NAPI) is a research tool to monitor the developmental progress and differential maturity of preterm infants ranging between 32weeks and 37weeks (full term). This test is used to identify persistent lags in development, as a research tool to assess effects of interventions and to study individual differences and basic developmental questions. The reliability and clinical validity of this test has been thoroughly investigated and normative data has been established. Objective - To evaluate the neurobehavioral development at 37weeks of post conceptional age in late preterm infants born to mothers with hemoglobin \<11gm/dl; by a standardised scale - Neurobehavioral Assessment of Preterm Infants (NAPI).

Design outcomes

Primary

Measure	Time frame	Description
Evaluation of neurobehavioral development	2 months	The two sub domains of Neurobehavioral Assessment of Preterm Infants (NAPI) i.e. Motor Development and Vigor (MDV) and Alertness and Orientations (AO) were tested to evaluate the neurobehavioral development at 37weeks of post conceptional age in late preterm neonates

Secondary

Measure	Time frame	Description
Comparison of NAPI Score	1 month	The scores of the two sub domains of Neurobehavioral Assessment of Preterm Infants (NAPI) i.e. Motor Development and Vigor (MDV) and Alertness and Orientations (AO) were compared to determine the level of maturity in the neurobehavioral development in cases and controls.
