Childhood malnutrition is a global public health issue with devastating consequences on the health, well-being, and psychosocial development of children. Emerging evidence suggests that malnourished children have immature gut microbiota compared to age-matched healthy controls and it does not repair even after nutritional interventions. The present study aims to characterize how the gut microbiome develops during the first two years of life in children residing in malnutrition endemic areas of Khyber Pakhtunkhwa, the region with the highest prevalence of childhood malnutrition in Pakistan and the region.

Malnutrition in children remains a global public health challenge. The consequences are often severe and deadly, particularly in low- and middle-income countries where malnutrition contributes to \ half of deaths in children under five years of age. Pakistan is among those nations with the highest burden of stunting (40.2%), wasting (17.7%), and micronutrient deficiency in children under five years of age. Recently, scientists discovered that the trillions of microbes (gut microbiome) that live in the human gut affect the nutritional status and overall health of children during the initial years of life. In this context, research studies from developing countries, where malnutrition is common, have reported an impaired or immature gut microbiome in malnourished (stunted, wasted, and underweight) children compared to matched healthy controls and it does not repair even after nutritional intervention. Therefore, a nutritional intervention strategy that does not take into account the gut microbiome microbiota will fail to ameliorate the long-term consequences of malnutrition. In this prospective cohort study from Pakistan, healthy infants (n=70) aged 0 - 28 days will be recruited from rural and remote areas of District Swat and followed at 3, 6, 12, 18 and 24 months. Ante-natal and postnatal history, Dietary intake data, dietary diversity, Infant and young child feeding (IYCF practices), and Health outcomes data will be collected at baseline and followup. The investigators will also collect dry blood spot, stool and oral swab samples and conduct anthropometric assessments of both mother and the baby at each time point. Advanced, next-generation sequencing technology will be used to explore gut microbiome diversity and functional potential.
