Hunger and malnutrition are not problems exclusive to low income countries.

That is why the international community cannot realise its ambitious international agenda of achieving zero hunger and malnutrition without a renewed focus on countries in economic transition where hunger and malnutrition remain.

The majority of the world’s hungry and malnourished population now live in Middle Income Countries (MICs).

For these countries to best fulfil their vital role in supporting zero hunger and malnutrition, they must promote effective country-led strategies that will reduce hunger and malnutrition at home.

Abstract

Physical height is an important economic variable reflecting health and human capital. Puzzlingly, however, differences in average height across developing countries are not well explained by differences in wealth. In particular, children in India are shorter, on average, than children in Africa who are poorer, on average, a paradox called \the Asian enigma” which has received much attention from economists.

 Could toilets help children grow tall, while disease externalities from poor sanitation keep children from reaching their height potentials? This paper provides the first identification of a quantitatively important gradient between child height and sanitation, which can statistically explain a large fraction of international height differences.

I apply three complementary empirical strategies to identify the association between sanitation and child height: country-level regressions across 140 country-years in 65 developing countries; within-country analysis of differences over time within Indian districts; and econometric decomposition of the India-Africa height difference in child level data.

 The effect of sanitation on human capital is quantitatively robustly estimated across these strategies, and does not merely reflect wealth or other dimensions of development. Open defecation, which is exceptionally widespread in India, can account for much or all of the excess stunting in India.

Abstract

Poor sanitation remains a major public health concern linked to several important health outcomes; emerging evidence indicates a link to childhood stunting. In India over half of the population defecates in the open; the prevalence of stunting remains very high. Recently published data on levels of stunting in 112 districts of India provide an opportunity to explore the relationship between levels of open defecation and stunting within this population. We conducted an ecological regression analysis to assess the association between the prevalence of open defecation and stunting after adjustment for potential confounding factors. Data from the 2011 HUNGaMA survey was used for the outcome of interest, stunting; data from the 2011 Indian Census for the same districts was used for the exposure of interest, open defecation. After adjustment for various potential confounding factors – including socio-economic status, maternal education and calorie availability – a 10 percent increase in open defecation was associated with a 0.7 percentage point increase in both stunting and severe stunting. Differences in open defecation can statistically account for 35 to 55 percent of the average difference in stunting between districts identified as low-performing and high-performing in the HUNGaMA data. In addition, using a Monte Carlo simulation, we explored the effect on statistical power of the common practice of dichotomizing continuous height data into binary stunting indicators. Our simulation showed that dichotomization of height sacrifices statistical power, suggesting that our estimate of the association between open defecation and stunting may be a lower bound. Whilst our analysis is ecological and therefore vulnerable to residual confounding, these findings use the most recently collected large-scale data from India to add to a growing body of suggestive evidence for an effect of poor sanitation on human growth. New intervention studies, currently underway, may shed more light on this important issue.

Introduction

click here for to download this paper

A country truly concerned about its development would put its children’s health on a higher priority than the GDP. For, population of over a billion can add strength to a country, only, if it is healthy and productive.

In India about 42% of the children are under weight. It has been reported by that on in every three most malnourished children of the world live in India. It is cause worry because such a populace can become a liability in the coming years. The problem of malnutrition is a matter of shame. Despite impressive growth in our GDP, the level of under nutrition in the country is unacceptably high . India has not succeeded in reducing malnutrition fast enough, though the integrated child development services (ICDS) programme continues to be our most important tool to fight malnutrition.

The global community has designated halving the prevalence of under weigh children by 2015 as a key indicator of progress towards the millennium development goal (MDG) of eradicating extreme poverty and hunger. However, it appears that that economic growth alone, though impressive, will not reduce malnutrition sufficiently to meet the MDG. Nutrition target. India’s main early child development and nutrition intervention , the ICDS program has expanded steadily across the country during the last more than three and half decade of its existence. It is one of the World’s largest, most unique well designed and well placed programme to address many of the underlying cause of under nutrition in India. However, it faces a range of implementation difficulties that prevent it from fully realizing its potential.

This article is an attempt to critically examine the World largest programme and identifies the most important weakness in the implementation of ICDS and suggest a way out that can be taken to improve the impact of the programme.

Video – The Republic Of Hunger: every third malnourished child in the world is from India

In Under-nutrition on August 16, 2012 at 6:53 am

From AlJazeera web site:

“More than 40 per cent of India’s 61 million children are malnourished, prompting the prime minister to declare the problem a “national shame”.

“A recent report reveals that levels are twice that of sub-Saharan Africa, making every third malnourished child in the world an Indian.

“India has one of the fastest-growing economies in the world and runs one of the largest child feeding programmes.

“But critics say only a fraction of aid reaches the needy.”

Slums and Malnourishment: Evidence From Women in India

In Under-nutrition on June 3, 2012 at 8:25 am

by H Swaminathan and A Mukherji

Am J Public Health, May 17, 2012

Abstract

Objectives. We examined the association between slum residence and nutritional status in women in India by using competing classifications of slum type.

Methods. We used nationally representative data from the 2005-2006 National Family Health Survey (NFHS-3) to create our citywide analysis sample. The data provided us with individual, household, and community information. We used the body mass index data to identify nutritional status, whereas the residential status variable provided slum details. We used a multinomial regression framework to model the 3 nutrition states-undernutrition, normal, and overnutrition.

Results. After we controlled for a range of attributes, we found that living in a census slum did not affect nutritional status. By contrast, living in NFHS slums decreased the odds of being overweight by 14% (95% confidence interval [CI]?=?0.79, 0.95) and increased the odds of being underweight by 10% (95% CI?=?1.00, 1.22).

Conclusions. The association between slum residence and nutritional outcomes is nuanced and depends on how one defines a slum. This suggests that interventions targeted at slums should look beyond official definitions and include current living conditions to effectively reach the most vulnerable.

Abstract

BACKGROUND: Despite the high and relatively stable overall growth of the economy, India’s agriculture sector is underperforming and a vast section of the population remains undernourished.

OBJECTIVE: To explore the possible interplay between agricultural performance and malnutrition indicators to see whether states that perform better in agriculture record better nutritional outcomes.

METHODS: Correlation analysis and a simple linear regression model were used to study the relationship between agricultural performance and malnutrition among children under 5 years of age and adults from 15 to 49 years of age at 20 major states using data from the National Family Health Survey-3 for the year 2005/06 and the national accounts.

RESULTS: Indicators of the level of agricultural performance or income have a strong and significant negative relationship with indices of undernutrition among adults and children, a result suggesting that improvement of agricultural productivity can be a powerful tool to reduce undernutrition across the vast majority of the population. In addition to agriculture, access to sanitation facilities and women’s literacy were also found to be strong factors affecting malnutrition. Access to healthcare for women and child-care practices, in particular breastfeeding within 1 hour after birth, are other important determinants of malnutrition among adults and children.

CONCLUSIONS: Malnutrition is a multidimensional problem that requires multisectoral interventions. The findings show that improving agricultural performance can have a positive impact on nutritional outcomes. However, improvements in agriculture alone cannot be effective in combating malnutrition if several other mediating factors are not in place. Interventions to improve education, health, sanitation and household infrastructure, and care and feeding practices are critical. Innovative strategies that integrate agriculture and nutrition programs stand a better chance of combating the malnutrition problem.

The effect of a vaccination program on child anthropometry: evidence from India’s Universal Immunization Program.

J Public Health, May 18, 2012

BACKGROUND: Childhood vaccination may protect children’s nutritional status and lead to improved child growth in developing countries. This study evaluates the effect of India’s childhood vaccination program Universal Immunization Program (UIP) on the growth of children under 4 years of age.

METHODS: Regression models were estimated to examine the effect of UIP on vaccination status and children’s anthropometric outcomes. Regression models were also estimated to test whether UIP’s effect was uniform across various subpopulations of Indian children.

RESULTS: UIP increased height-for-age among Indian children who were <4 years of age in 1992-1993, resulting in a 17-22% reduction in the height-for-age-deficit of the average child. The program appears to have had no effect on other anthropometric indicators or vaccination status. UIP also led to differential changes in anthropometry and vaccination status, based on differences in maternal education and scheduled-caste status.

CONCLUSIONS: UIP led to improved child growth. This suggests that vaccination programs-in addition to being a major intervention for reducing child mortality-might be considered a tool for mitigating undernutrition in developing countries. This study also adds to the growing evidence that childhood vaccination programs are high-return investments because they produce long-term health benefits for children.

Abstract

Context: Severe acute malnutrition (SAM) in children is a significant public health problem in India with associated increased morbidity and mortality. The current WHO recommendations on management of SAM are based on facility based treatment. Given the large number of children with SAM in India and the involved costs to the care-provider as well as the care-seeker, incorporation of alternative strategies like home based management of uncomplicated SAM is important. The present review assesses (a) the efficacy and safety of home based management of SAM using ‘therapeutic nutrition products’ or ready to use therapeutic foods (RUTF); and (b) efficacy of these products in comparison with F-100 and home-based diet.

Evidence Acquisition: Electronic database (Pubmed and Cochrane Controlled Trials Register) were scanned using keywords ‘severe malnutrition’, ‘therapy’, ‘diet’, ‘ready to use foods’ and ‘RUTF’. Bibliographics of identified articles, reviews and books were scanned. The information was extracted from the identified papers and graded according to the CEBM guidelines.

Results: Eighteen published papers (2 systematic reviews, 7 controlled trials, 7 observational trials and 2 consensus statements) were identified. Systematic reviews and RCTs showed RUTF to be at least as efficacious as F-100 in increasing weight (WMD=3.0 g/kg/day; 95% CI -1.70, 7.70) and more effective in comparison to home based dietary therapies. Locally made RUTFs were as effective as imported RUTFs (WMD=0.07 g/kg/d; 95% CI=-0.15, 0.29). Data from observational studies showed the energy intake with RUTF to be comparable to F-100. The pooled recovery rate, mortality and default in treatment with RUTF was 88.3%, 0.7% and 3.6%, respectively with a mean weight gain of 3.2 g/kg/day. The two consensus statements supported the use of RUTF for home based management of uncomplicated SAM.

Conclusions: The use of therapeutic nutrition products like RUTF for home based management of uncomplicated SAM appears to be safe and efficacious. However, most of the evidence on this promising strategy has emerged from observational studies conducted in emergency settings in Africa. There is need to generate more robust evidence, design similar products locally and establish their efficacy and cost-effectiveness in a ‘non-emergency’ setting, particularly in the Indian context.
