In 2017, both the marginalized and the Brahmin and Chhetri communities had equal prevalence of stunting among children under five. By 2022, the marginalized communities have shown a significantly faster reduction in the prevalence of stunting compared to the Brahmin and Chhetri communities. As a result of this differential improvement, although the prevalence of stunting has decreased the gap between these two groups has widened over time.

From 2017 to 2022 the hill and terai regions showed significant progress in reducing the prevalence of stunting, with an 8 and 5 percentage point reduction, respectively. However, the mountain region had the least progress, with only a 2 percentage point decrease in stunting rates during the same period. These varying rates of decrease in stunting prevalence have resulted in the gaps between the three regions widening.
