Economic growth & health of poor children in India.

Sir,

The prevailing wisdom to improve the health of Indians, as repeatedly emphasized by the Prime Minister of India Dr Manmohan Singh1, is based on economic growth. Can India rely solely on the trickle-down process of economic growth to improve the health of its population, especially its children from socio-economically disadvantaged backgrounds? India experienced substantial economic growth with an average growth rate of 6.4 per cent between 1992/93 and 2005/062, with approximately a 50 per cent increase in its growth rate. During the same time, the decrease in the prevalence of underweight among children was sluggish with negligible reductions especially in the poorest quintile of household wealth (Fig. 1). At the ecological level, there was no association between per cent increase in per capita income of the state and per cent change in underweight among children in the poorest wealth quintile (Fig. 2). This appears to be in line with a recently published study3 that examined and found no effect of economic growth on the child's risk of being undernourished in data pooled across all wealth quintiles.

As the economist-philosopher Amartya Sen continues to remind us, economic growth is neither a necessary nor a sufficient condition to improve population health4. The discussion of the merits of economic growth as a primary policy instrument to improving the health of the poor has to also consider the questions of what type of economic growth is needed, i.e., is the process generating growth ‘inclusive’ involving and benefiting all sections (especially its poorer citizens) of the society; and how are the anticipated increases in public revenue that accrues as a result of economic growth being allocated to different programmes? Existing evidence for an inclusive economic growth5, or for increased public spending on health6, in India is, however, not encouraging. Taken together, the evidence suggests that sole reliance on economic growth as a policy instrument may not be sufficient to reduce the burden of poor health among children from disadvantaged households in India. Simultaneous and direct health investments may be necessary to reduce the high levels of child undernutrition in India, especially given the strong intergenerational effects of poor nutrition in India6.
