Lo de siempre... no tenemos un problema de producción (traducido económicamente en el concepto riqueza). Tenemos un problema de desigualdad social y de reparto de la riqueza.

Background

Economic growth is widely regarded as a necessary, and often sufficient, condition for the improvement of population health. We aimed to assess whether macroeconomic growth was associated with reductions in early childhood undernutrition in low-income and middle-income countries.

Methods

We analysed data from 121 Demographic and Health Surveys from 36 countries done between Jan 1, 1990, and Dec 31, 2011. The sample consisted of nationally representative cross-sectional surveys of children aged 0—35 months, and the outcome variables were stunting, underweight, and wasting. The main independent variable was per-head gross domestic product (GDP) in constant prices and adjusted for purchasing power parity. We used logistic regression models to estimate the association between changes in per-head GDP and changes in child undernutrition outcomes. Models were adjusted for country fixed effects, survey-year fixed effects, clustering, and demographic and socioeconomic covariates for the child, mother, and household.

Findings

Sample sizes were 462 854 for stunting, 485 152 for underweight, and 459 538 for wasting. Overall, 35·6% (95% CI 35·4—35·9) of young children were stunted (ranging from 8·7% [7·6—9·7] in Jordan to 51·1% [49·1—53·1] in Niger), 22·7% (22·5—22·9) were underweight (ranging from 1·8% [1·3—2·3] in Jordan to 41·7% [41·1—42·3] in India), and 12·8% (12·6—12·9) were wasted (ranging from 1·2% [0·6—1·8] in Peru to 28·8% [27·5—30·0] in Burkina Faso). At the country level, no association was seen between average changes in the prevalence of child undernutrition outcomes and average growth of per-head GDP. In models adjusted only for country and survey-year fixed effects, a 5% increase in per-head GDP was associated with an odds ratio (OR) of 0·993 (95% CI 0·989—0·995) for stunting, 0·986 (0·982—0·990) for underweight, and 0·984 (0·981—0·986) for wasting. ORs after adjustment for the full set of covariates were 0·996 (0·993—1·000) for stunting, 0·989 (0·985—0·992) for underweight, and 0·983 (0·979—0·986) for wasting. These findings were consistent across various subsamples and for alternative variable specifications. Notably, no association was seen between per-head GDP and undernutrition in young children from the poorest household wealth quintile. ORs for the poorest wealth quintile were 0·997 (0·990—1·004) for stunting, 0·999 (0·991—1·008) for underweight, and 0·991 (0·978—1·004) for wasting.

Interpretation

A quantitatively very small to null association was seen between increases in per-head GDP and reductions in early childhood undernutrition, emphasising the need for direct health investments to improve the nutritional status of children in low-income and middle-income countries.
