Stunting, wasting and underweight—the three traditional indicators of undernourishment among children—provide mutually non-exclusive categories of anthropometric failures: low height for age, low weight for height and low weight for age. Although these indicators are essential for designing specific clinical and child nutrition policy interventions, they fall short of estimating the prevalence of overall anthropometric failure, which provides a sense of the scale of the nutrition problem. This article estimates the alternative, more comprehensive measure Composite Index of Anthropometric Failure (CIAF) for Indian states, based on data from the National Family Health surveys of 2006 and 2016, for children under five years (Ch–U5). The CIAF-based undernutrition estimates show significantly high anthropometric failure levels among Indian children compared to only stunting, wasting and underweight. Based on population projections for Ch–U5, we also show that a sizeable number of states may have seen an increase in child undernutrition between 2006 and 2016. We also correlated CIAF with household wealth index scores and found a positive relationship with children facing no anthropometric failure.

<sec> <title>OBJECTIVE:</title> To study the involvement and influence of local participatory governments consisting of Panchayat Raj institutions (PRIs) in implementing evidence-based interventions for eliminating maternal and child undernutrition in the state of Kerala, India. </sec> <sec> <title>METHODS:</title> In-depth interviews were carried out among stakeholders in six selected local governments using a semi-structured questionnaire. Transcribed interviews were coded and thematically analysed. </sec> <sec> <title>RESULTS:</title> PRIs facilitated nutrition interventions through additional resource mobilisation, nutrition monitoring and surveillance, acting as a more approachable point of governance, utilising general acceptance to mobilise volunteers to tackle local challenges, enabling formal and informal platforms for community participation and spaces of co-creation. Changes in the attitude of different stakeholders, timely policy backing and support, and interconnections at the local level aided the process. Gaps exist in awareness creation, dietary diversification, feeding behaviours, maternal mental health, infrastructure development, monitoring of anthropometric indicators and planning for nutrition interventions during emergencies. </sec> <sec> <title>CONCLUSION:</title> Results illustrate complex linkages PRIs have within the health system and how these linkages help in the implementation of interventions. The study explored previously identified pathways from the literature and identified additional pathways through which local participatory governance contributes to the successful implementation of nutrition interventions. </sec>
