New research published in BMJ Nutrition Prevention & Health reveals a concerning correlation between residing at higher altitudes in India and an elevated risk of stunted growth in children. The study, drawing on data from the 2015–16 National Family Health Survey (NFHS-4), underscores the urgency of prioritizing nutritional interventions in hilly and mountainous regions to combat the pervasive issue of childhood stunting.
Conducted by a team of researchers, the study found that children residing in homes situated 2,000 meters or more above sea level faced a 40% higher risk of stunted growth compared to those living 1,000 meters below. Of the 167,555 children under the age of 5 included in the analysis, the prevalence of stunting was alarmingly high, affecting over a third of 5-year-olds.
Rural areas emerged as particularly vulnerable, with the majority of affected children residing in these regions. The prevalence of stunting was notably higher among children aged 18–59 months, underscoring the critical importance of early intervention in addressing this issue. Factors such as maternal education, antenatal care, and access to health facilities were identified as influential determinants of childhood stunting.
While the study did not establish altitude as a direct cause of stunting, researchers proposed plausible explanations for their findings, including reduced appetite, limited nutrient absorption, and food insecurity associated with chronic exposure to high altitude environments. Moreover, challenges in healthcare provision and access exacerbate the vulnerability of children living in these regions.
In light of these findings, researchers advocate for a multipronged approach encompassing reproductive health initiatives, women’s nutrition programs, and infant and young child feeding interventions tailored to high-risk areas. Professor Sumantra Ray, Executive Director of the NNEdPro Global Institute for Food, Nutrition and Health, emphasized the need for further research to elucidate the complex interplay of factors contributing to malnutrition in hilly regions.
As India grapples with the persistent challenge of childhood stunting, evidenced-based policies and targeted interventions are essential to ensure every child has the opportunity for healthy growth and development. The study serves as a clarion call for concerted efforts across health and nutrition sectors to address the multifaceted determinants of malnutrition and safeguard the well-being of future generations.
