 It is worth mentioning that substantial improvement in development is unlikely to be made without also increasing early learning opportunities, though there has been recent attention to the effect of nutrition on development. Non-US intervention studies showed that cognitive benefits were better in case of interventions having stimulation and education components compared with those involving nutrition or economic assistance only. In Bangladesh, research revealed that almost 60 children are exposed to risk of insufficient development caused by high prevalence of LBW 22, stunting 41, and poverty 43, and lack of early stimulation due to low parental knowledge. Most of the data from developing countries including Bangladesh mainly focused on cognitive and motor outcome with less emphasis on maternal cognitive ability. This is why, in addition to the existing information, the investigators need to assess maternal cognitive ability and neurobehavioral development in order to prepare appropriate intervention particularly for disadvantaged children living in poverty in Bangladesh.
