16S rRNA gene amplicon sequencing data from the gut microbiota of adolescent Afghan refugees.

The gut microbiota residing in the distal ileum and colon is the most complex, diverse, and densest microbial ecosystem in the human body. Despite its known role in human health and disease, gut microbiome diversity and function are rarely explored in vulnerable populations such as refugees. The current study aimed to explore gut microbiota diversity and sources of variation among adolescent Afghan refugees residing in Peshawar, Pakistan. Stool samples were collected from 10 - 18 years old, healthy adolescents (n=205) for 16S rRNA gene sequence (V4-V5 hypervariable region) analysis on isolated faecal DNA. Bioinformatics analyses were performed using Kraken2, Bracken and Phyloseq. The data presented here will allow researchers to profile the gut microbiota of this rarely explored, vulnerable population who are at high risk of food insecurity and malnutrition. The data can be used to provide insight on the impact of demographic characteristics, dietary intake, nutritional status, and health on gut microbiome diversity, and enables a comparative analysis with similar data sets from other population groups of relevance. The amplicon sequencing data are deposited in the NCBI Sequence Read Archive as BioProject PRJNA1105775.
