BackgroundStunting, defined as z-score height-for-age (HAZ) < -2, is an important contributor to the burden of childhood undernutrition among slum-dwelling residents in India's metropolitan areas. Calcutta Rescue (CR) is a non-governmental organisation that provides medical care and nutritional support to slum-dwellers in Kolkata, India. CR undertook a study in Liluah Bhagar, an urban slum, to 1) establish the prevalence of undernutrition among children under five years of age, 2) evaluate the impact of a pilot nutritional support programme on growth patterns of a consecutively selected group of stunted children, and 3) identify socio-economic predictors of stunting.
MethodsFor the prevalence assessment (April-June 2018), we conducted anthropometric measurements using standardised World Health Organization (WHO) growth measurements for weight-for-age (WAZ), height-for-age (HAZ), and weight-for-height (WFH). For the longitudinal study, we recruited stunted children and collected anthropomorphic data every three months for one year (December 2018-December 2019).
ResultsThe prevalence assessment of 116 children revealed 59% of stunting, 44% underweight and 12% of wasting. Follow-up of 42 stunted children in a pilot nutritional programme improved stunting over time (b =0.07, 95% CI 0.05 to 0.039, P<0.001), with a trend towards clinical improvement at one year. Linear mixed model analysis revealed household income was a negative predictor of stunting (b =-0.38, 95% CI -0.66 to -0.09, P=0.010).
ConclusionsThis study highlights the burden of undernutrition in marginalised slum-dwelling children in India and the benefits of a pragmatic, education-focused nutritional intervention programme. Further studies are required to determine what predictors other than income are associated with stunting to then determine what interventions are likely to effect long-lasting and sustainable changes to growth in this vulnerable population.Childhood undernutrition, which includes underweight (low weight-for-age, or WAZ), wasting (low weight-forheight, WFH), stunting (low height-for-age, or HAZ) and micronutrient deficiencies, is a persisting problem in India where the national under-five prevalence of wasting (20.8%) and stunting (37.9%) is higher than the developing country average of 8.9% and 25%, respectively. 1 Undernutrition in early childhood has far reaching consequences: recent data indicate that malnutrition is the sin-gle biggest contributing risk factor in up to 68.7% of deaths in children aged 5 years and under. 2 Other studies have linked undernutrition and stunting in early childhood to impaired cognitive development, increased risk of disease, and suboptimal productivity in later life. [2][3][4][5] Whilst sustained economic growth in the last 20 years has lifted millions out of poverty in India, persisting social inequalities contribute to a high burden of poverty-related illnesses that are particularly marked in urban slums. 5,6 Scopazzini MS, Raoult V, Kuruttuparambil S, Sulkers E.
