Gut microbiota differences in stunted and normal-lenght children aged 36-45 months in East Nusa Tenggara, IndonesiaOriginal paper
Karen Pendergrass is a microbiome researcher specializing in microbiome-targeted interventions (MBTIs). She systematically analyzes scientific literature to identify microbial patterns, develop hypotheses, and validate interventions. As the founder of the Microbiome Signatures Database, she bridges microbiome research with clinical practice. In 2012, based on her own investigative research, she became the first documented case of FMT for Celiac Disease, four years before the first published case study.

This study compared the gut microbiota of stunted and normal-length young children in Indonesia. It sequenced the V3-V4 region of the 16S rRNA gene from stool and measured fecal short-chain fatty acids by GC-MS. Microbiota were correlated with growth z-scores and sanitary conditions. Two sites, one urban and one rural, were sampled. The aim was to find microbial taxa associated with stunting.
Who was studied?
The cohort was 200 children aged 36 to 45 months in East Nusa Tenggara, Indonesia. It included 100 stunted and 100 non-stunted children, split across Kupang (urban) and North Kodi (rural). Stunted children averaged about 8 cm shorter and were lighter, while ages did not differ (p = 0.62). The design was cross-sectional, with no intervention. Stunting was defined as a length-for-age z-score below minus two.
What were the most important findings?
Bacteroidetes were higher in stunted children (23.9% versus 20.0%, p = 0.014), as were Cyanobacteria (p = 0.048). Three genera were consistently higher in stunted children at both sites: Lachnoclostridium, Faecalibacterium, and Veillonella. Faecalibacterium reached 13.3% in stunted versus 8.8% in non-stunted children (p = 3.1 x 10 to the minus 4). Fecal acetate (p = 0.003), propionate (p = 0.035), and total short-chain fatty acids (p = 0.011) were lower in stunted children. Butyrate did not differ significantly (p = 0.67).
What are the greatest implications of this study?
Lower short-chain fatty acids suggest reduced energy extraction and possibly weaker gut barrier function in stunted children. Certain genera track with stunting, offering candidate targets for dietary and sanitation interventions. The signature differed from the same team's earlier study on Java, showing strong geographic variation. No causation is established, and these are cross-sectional correlations.
