India’s salt iodization programme has a 50 year history and has made remarkable progress towards the achievement of universal salt iodization. A national policy of universal salt iodization was adopted in 1986 and subsequent legislation, both at the national and the state level, prohibits the sale of non-iodized salt for human consumption.1 Sustained efforts to ensure an adequate supply of iodized salt helped India to reach self-sufficiency in its production.2 As a result, in 2009, approximately 71% of households were consuming salt with adequate levels of iodine (i.e. ≥ 15 parts per million).3 However, an average of 249 million Indians, including 8 million children born annually, remain susceptible to iodine deficiency disorders (IDDs). Moreover, the use of adequately iodized salt varies widely by state, from roughly 30% in Chhattisgarh to 98% in Manipur.3 Notably, coverage steadily improves as the household wealth index increases. Hence, the most disadvantaged population groups are the most susceptible to IDDs.3 For this reason, adequately iodized salt needs to be made available and accessible to the poor and most marginalized if the goal of universal salt iodization is to be met in India.
Madhya Pradesh, located in central India, is territorially the second largest state in India and has more than 72 million inhabitants.4 The state is home to a substantial proportion of India’s socially and economically deprived population. Approximately 18% and 21% of the population belong to scheduled castes and scheduled tribes, respectively, and 37% fall in India’s lowest wealth quintile.4,5 Malnutrition is prevalent. Half of the children less than 5 years of age are stunted (height-for-age z-score < −2) and 35% are wasted (weight-for-height z-score < −2) by WHO Child Growth Standards;6 74% of children aged 6 to 9 months are anaemic (haemoglobin concentration < 110 g/l).5 Currently, no data are available on the iodine status of the state population based on urinary iodine concentration or the prevalence of goitre, but in 2009 only 63% of households were consuming adequately iodized salt, whereas 18% were using non-iodized salt.3 Remarkably, the proportion of households using adequately iodized salt was about 50% in the lowest wealth quintile and around 86% in the highest wealth quintile.3
Since Madhya Pradesh is not a salt-producing state, it imports all edible salt from the neighbouring states of Rajasthan and Gujarat. About 35% of the edible salt enters the state by rail and the remainder by road.2 This poses major difficulties because salt is monitored for adequate iodine content before shipment by rail but not before shipment by road.7 Only salt that has been adequately iodized is authorized for rail transportation, but virtually any type of edible salt can enter the state by road. In addition, inadequately iodized salt is often sold at a lower price than adequately iodized salt and is hence more attractive to many consumers, especially the poorest and the uninformed.
Poor access to adequately iodized salt, particularly among the lower wealth quintiles of the population, has prompted sustained pressure from advocacy groups demanding that the state government accelerate efforts towards attaining universal salt iodization. As a result, in 2009 the government decided to take steps towards ensuring the use of adequately iodized salt through two national flagship nutrition programmes that target the most vulnerable population groups in Madhya Pradesh: the Supplementary Nutrition Programme of the Integrated Child Development Services and the Midday Meal Scheme.
The Integrated Child Development Services, launched in 1975, provide supplementary feeding, immunization, health check-ups and nutrition education to all children younger than 6 years and pregnant and lactating mothers to promote healthy child growth and development.8 All services are delivered by community-based anganwadi workers through a network of anganwadi centres (literally “courtyard shelters”), which are government-sponsored centres offering care to children and mothers. The Supplementary Nutrition Programme provides food in the form of dry take-home rations for pregnant and lactating women and for children 6 to 35 months old, as well as hot cooked meals for children between the ages of 3 and 6 years.8 The primary aim of the Supplementary Nutrition Programme is to enhance the calorific intake of children and women in low-income communities. The Midday Meal Scheme is a school meal programme providing lunch free of charge to children aged 6 to 14 years to improve children’s nutritional status and enhance school enrolment and attendance.9
In general, the Supplementary Nutrition Programme and the Midday Meal Scheme operate independently. However, in 2009 the government of Madhya Pradesh launched Sanjha Chulha (community kitchen), a state-wide joint feeding programme that converged the two earlier programmes. All hot meals served at anganwadi centres and schools are now prepared in a common kitchen. Two hot meals are served daily at anganwadi centres to children aged 3 to 6 years, and one cooked meal is served to schoolchildren every school day. In addition, every Tuesday children 6 to 36 months of age, pregnant and lactating women and adolescent girls enrolled at anganwadi centres receive a hot meal. Sanjha Chulha was initiated so that instead of spending time preparing hot meals, anganwadi workers could devote more time to nutrition and health education, home visits and counselling.
In 2009, Sanjha Chulha was identified as an appropriate platform for ensuring access to adequately iodized salt for economically deprived populations. Two directives were subsequently issued – one in 2009 by the Department of Women and Child Development and another in 2011, by the Department of Panchayat and Rural Development. Both made it a requirement that only adequately iodized salt be used for preparing hot meals for anganwadi centres and schools and that only adequately iodized salt be used to prepare the dry take-home rations (mix of rice with lentils or wheat and of soya flour with Bengal gram or wheat flour) for pregnant and lactating women and young children.
District authorities began to implement Sanjha Chulha as prescribed. Programme staff were trained on the health and nutrition benefits of using iodized salt and were taught how to correctly store salt in the common kitchen and to monitor the iodine level of the salt using salt testing kits. Sanjha Chulha is supervised regularly by government officials who assess the overall implementation of the programme and test the iodine content of the salt used. In addition, field monitors sponsored by the United Nations Children’s Fund test the iodine content of the salt in the common kitchen monthly. Each field monitor covers about three districts over a three-month period. A fixed number of common kitchens in each district is randomly selected for a visit during which field monitors take a random sample of salt to test its iodine content using a salt testing kit. They also monitor how the salt is stored, the type of salt packet used (preferably thick polyethylene) and kitchen hygiene.
The latest reports indicate that Sanjha Chulha has been successfully implemented in all anganwadi centres (n = 78 929) across Madhya Pradesh. Between June 2011 and March 2012, 28 507 407 (83%) children 6 to 35 months old who were enrolled in the anganwadi centres received one weekly take-home ration prepared using adequately iodized salt; additionally, 12 113 584 (89%) children aged 3 to 6 years enrolled in the anganwadi centres received two hot meals a day that had been prepared with adequately iodized salt for more than 21 days per month. Sanjha Chulha has also been successfully implemented in all primary (n = 85 054) and secondary schools (n = 28 652) participating in the Midday Meal Scheme. Between April 2011 and March 2012, a total of 5 751 979 (78%) primary-school children and 2 704 692 (79%) secondary-school children received one hot cooked meal prepared using adequately iodized salt on every school day.
The monthly monitoring data collected by the field monitors indicate that 79% and 83% of the common kitchens visited in 2010 (n = 1154) and 2011 (n = 1096), respectively, were consistently using adequately iodized salt to prepare hot meals. The remaining kitchens were also using iodized salt that showed adequate iodine levels in the packaging and labelling but suboptimal levels when tested because of inappropriate salt storage methods. In such cases, programme staff members were retrained in the correct way to store iodized salt.
Discussion and lessons learnt
India’s national flagship feeding programmes provide an effective delivery platform for increasing access to and use of adequately iodized salt among the most vulnerable and disadvantaged communities. The two state government directives described herein led to a change in salt procurement practices, with only iodized salt bearing a “smiling sun” logo on the package recommended for procurement. The smiling sun logo is a voluntary certification used by salt producers registered with the government to indicate that the salt has been adequately iodized. Thus, the use of adequately iodized salt in the feeding programme improved substantially after the directives were issued. A large number of preschool and school-aged children from low-income families received hot meals and women and young children received dry take-home rations prepared with salt that had been adequately iodized. Without the joint feeding programme, this segment of the population would have had little access to adequately iodized salt and would have remained at risk of IDDs. Programme sustainability is ensured because funding for the programme is budgeted under the Integrated Child Development Services project implementation plan.
The planning and implementation of the feeding programme was fraught with challenges. Although some could be overcome, others remain. Sanjha Chulha is a feeding programme involving three different government departments in Madhya Pradesh: the Department of Women and Child Development, the Department of Panchayat and Rural Development and the Department of Education. Thus, one of the most important challenges at the outset was to convince the three different departments in the state government to issue a joint directive. This required intensive advocacy efforts based on the scientific evidence of the prevalence of iodine deficiency disorders in India and the importance of using adequately iodized salt to prevent iodine deficiency. In addition, it was not easy to achieve convergence among the three key departments, particularly in terms of fund transfers, staff training and programme monitoring. A series of joint planning and review meetings were organized in an effort to enhance collaboration and coordination among the three departments.
Given the massive scale of the feeding programme, proper monitoring and evaluation remains a major challenge. It currently focuses on monitoring coverage, iodine content, salt storage conditions and kitchen hygiene. However, the feeding programme lacks a standard monitoring mechanism for determining the actual consumption of adequately iodized salt. In addition, the limited, irregular supply of salt testing kits has hampered monitoring of the iodine content of the salt used in the common kitchens. Efforts are currently being made to improve management of the supply of salt testing kits.
Clearly, the provision of adequately iodized salt in the feeding programme needs to be accompanied by intensive community education and communication activities to generate awareness of the health and nutrition benefits of iodized salt. However, this aspect has received little attention and the educational and informational materials being used at present at the community level need to be improved.
Three important lessons have been learnt (Box 1). Over the past few decades, India has made impressive progress towards the achievement of universal salt iodization. However, reaching the last 30% of households will be difficult, since these represent the more inaccessible, socioeconomically disadvantaged households. However, effective and innovative strategies are the key to addressing the remaining challenges. India has successful large-scale social safety net programmes aimed at the most economically deprived populations. Both national and state-level policies should mainstream the use of adequately iodized salt in feeding programmes for the benefit of all, especially the most vulnerable women and children.
Box 1. Summary of main lessons learnt
- Iodized salt has to be properly stored to maintain the optimal level of iodine, and staff should be trained accordingly.
- Efforts to create awareness in the community of the health and nutrition benefits of iodized salt should be undertaken alongside the feeding programmes.
- Programme monitoring needs to be strengthened and evaluations undertaken to generate evidence of the programme’s impact on the iodine status of the target population.
