Child undernutrition underestimated?……….R GAIHA, R JHA & V S KULKARNI
Poverty is multi-dimensional and money-metric indicators such as minimum income or expenditure cannot adequately capture all these dimensions.
Attention has therefore shifted to other indicators such as health status that relate more closely to basic capabilities of individuals. As Amartya Sen has reminded us, the correspondence between basic capabilities (e.g., to live a healthy and productive life) and level of income is typically weak. It is, therefore, not surprising that welfare indicators including income/expenditure, health and education reflect a diverse pattern in India. While most indicators have continued to improve, social progress has followed diverse patterns , ranging from accelerated progress in some fields to slowdown and even regression in others. Specifically, a composite index of undernutrition of children under five years is about 60% or, six out of 10 children are undernourished tells a grim story of how nasty, brutish and short’ their lives aretells a grim story of how nasty, brutish and short’ their lives are, as sketched below.
The most commonly used anthropometric measures are stunting (low height for age), wasting (low weight for height) and underweight (( low weight for age). Stunting is an indicator of chronic undernutrition, attributable to prolonged food deprivation, and/or disease or illness; wasting is an indicator of acute undernutrition, caused by more recent food deprivation or illness; underweight is an indicator of both acute and chronic undernutrition. Children whose measurements fall below a certain threshold of the reference population, based on recent WHO standards, are considered undernourished : stunted, wasted or underweight.
An important feature of these indicators is the overlap between them: some children who are stunted will also have wasting and/or be underweight; those who have wasting will also be stunted or and/or underweight. So there is a need for a more comprehensive measure of child undernutrition . Such a measure is implemented in Gaiha, R, R Jha and Vani S Kulkarni (2010) Child Undernutrition in India’ , Canberra, Australian National University, mimeo.
Following Peter Svedberg, who has done important work on child undernutrition in India, a new aggregate indicator is constructed that encompasses all undernourished children, be they wasted and/or stunted and /or underweight. This is the composite index of anthropometric failure (CIAF).
The accompanying table points to more pervasive anthropometric failure in terms of the CIAF relative to conventional indicators of being underweight, stunted or wasted. The CIAF is about 59% (or, 6 out of 10 children are undernourished). Among the subcategories , stunting and underweight, and stunting alone account for well over half of the CIAF. Children who fail in all three dimensions (simultaneously wasted, stunted and underweight) account for a non-negligible share (13.5%). The underweight alone account for the lowest share (about 6%).
Recent evidence suggests that children suffering from more than one anthropometric failure are more susceptible to infectious diseases (e.g., diarrhoea, acute respiratory infection ) than those suffering from no failure or just one failure. Worse, these diseases are associated with high risks of child mortality. Our analysis confirms that, except for wasted and underweight and stunted only, in all other cases the prevalence of diarrhoea was higher than in the reference group of no failure . In fact, the highest prevalence rate was among children who were simultaneously stunted and underweight, and those who were wasted, underweight and stunted.
Our analysis of determinants of CIAF yields some new insights. Briefly, the larger the number of five-year old children, the greater is the
competition for food and health care, and the higher is the undernutrition. Maternal education reduces it, as it is linked to better child care and healthier diets. Quality of kitchen whether it has a vent contributes to more hygienic living conditions. Above all, the higher the income, the lower is child undernutrition. Somewhat surprising is the significant role of food prices in child undernutrition, as changes in relative prices induce substitutions between food commodities and in nutrient intake. Of particular significance, therefore, are prices of sugar, eggs and vegetables. While the price of milk is also positively related to undernutrition, the effect is not so robust. Lowering these prices is thus likely to contribute significantly to reduction in undernutrition. As food price stabilisation continues to elude policymakers, an option is to ensure better distribution of food through the Integrated Child Development Services (ICDS). Another priority is awareness building for hygienic living while female literacy grows. Although NREGS has contributed to livelihood expansion, problems abound in targeting the poorest.
Thus, a wide range of interventions is necessary that transcend income growth acceleration to ameliorate child undernutrition.
