Essential Interventions to Prevent Undernutrition in Infants and Young Children

Undernutrition remains one of the most pressing challenges affecting infants and young children, particularly in developing countries like India. The first 1,000 days of a child’s life – from conception to the second birthday – represent a critical window where the right nutritional interventions can shape lifelong health outcomes. Getting nutrition right during this period isn’t just about feeding; it’s about a series of well-timed, evidence-based practices that together build a strong foundation for survival, growth, and cognitive development.

Improving nutrition-related behaviours through IYCF practices 🔗

Combating undernutrition in neonates and young children begins with improving nutrition-related behaviours at the household and community levels. The framework for this is known as Infant and Young Child Feeding (IYCF), a set of guidelines promoted by the WHO and UNICEF to ensure every child receives optimal nutrition from birth. IYCF messaging focuses on a sequence of key practices: delayed cord clamping after birth, timely initiation of breastfeeding, exclusive breastfeeding for the first six months, introduction of complementary foods after six months, and dietary diversity for older infants and young children.

Each of these practices addresses a specific nutritional need at a specific stage. When implemented together, they form an interconnected chain that significantly reduces the risk of stunting, wasting, and micronutrient deficiencies. According to UNICEF, successful IYCF practices can prevent nearly one-fifth of deaths in children under five years of age.

Delayed cord clamping: the very first intervention 🔗

The first nutrition-related intervention happens within minutes of birth – delayed umbilical cord clamping. The WHO recommends that the umbilical cord should not be clamped earlier than one minute after birth, with an optimal delay of one to three minutes or until cord pulsation ceases. This practice allows additional blood to flow from the placenta to the newborn, improving iron stores during the first six months of life.

This is especially important for infants in low-resource settings who have limited access to iron-rich foods and are at greater risk of anaemia. Iron deficiency in early life is linked to delayed psychomotor development and impaired cognitive function later in childhood. Despite its simplicity, delayed cord clamping is not universally practised, and healthcare providers need to be trained to adopt it as a standard part of delivery care.

Timely initiation of breastfeeding 🔗

Children should be breastfed as soon as possible after birth – ideally within the first hour. This early initiation is critical because the first breast milk a mother produces is colostrum, a thick, yellowish fluid rich in antibodies (particularly secretory immunoglobulin A), white blood cells, protein, minerals, and fat-soluble vitamins like A, E, and K. As the WHO’s IYCF resource explains, colostrum provides vital immune protection to the infant when they are first exposed to the micro-organisms in the environment.

Early breastfeeding also promotes mother-child bonding and stimulates the hormonal responses – prolactin and oxytocin – needed for regular breast milk production. The sooner a baby starts nursing, the better the milk supply establishes itself.

However, the rates of early breastfeeding initiation remain far from ideal. According to the National Family Health Survey (NFHS-5), only about 41.8% of Indian children were breastfed within the first hour of birth. There is significant variation across states – Meghalaya reported the highest rate at approximately 80%, while Jharkhand recorded the lowest at around 22%. These disparities point to the influence of regional cultural practices, hospital protocols, and the level of counselling support available to new mothers.

Exclusive breastfeeding for the first six months 🔗

Exclusive breastfeeding (EBF) means feeding infants only breast milk – no water, other liquids, or solid foods – for the first six months of life. Breast milk is perfectly tailored to meet an infant’s nutritional needs during this period. It provides all the energy, nutrients, and hydration a baby needs, even in hot climates. Additionally, breast milk contains bioactive factors that protect against infections, particularly diarrhoeal diseases.

Introducing supplementary foods or liquids before six months is discouraged for several important reasons. First, early supplementation increases the risk of contamination and diarrhoeal illness, which further worsens nutritional status. Second, when a baby suckles less frequently, the mother’s milk production decreases – suckling frequency is the primary regulator of breast milk supply. This creates a cycle where reduced breastfeeding leads to lower milk output, pushing families toward further supplementation.

NFHS-5 data shows that approximately 63.7% of Indian infants are exclusively breastfed, which represents an improvement from 54.9% in NFHS-4. However, many infants still receive other liquids and foods before the six-month mark. The national median duration of exclusive breastfeeding stands at 3.9 months – well short of the recommended six months. One concerning trend is the increasing use of bottle-feeding, with about one in five infants aged 6-9 months being bottle-fed according to NFHS-4 data.

Complementary feeding after six months 🔗

After six months of exclusive breastfeeding, breast milk alone is no longer sufficient to meet a growing child’s energy and nutrient requirements. This is when complementary feeding – the introduction of solid, semi-solid, or soft foods alongside continued breastfeeding – becomes essential. The WHO and UNICEF recommend that breastfeeding continue alongside complementary foods for at least two years or beyond.

Appropriate complementary foods should include a variety of items from different food groups – grains, pulses, dairy, eggs, meat or fish, fruits, and vegetables. Special emphasis is placed on foods rich in vitamin A, such as orange and yellow fruits and vegetables, dark leafy greens, and animal-source foods. Data from national surveys shows that grain-based foods and vitamin A-rich fruits and vegetables are the most commonly consumed complementary foods among both breastfed and non-breastfed Indian children.

However, timely introduction of complementary feeding remains a challenge. NFHS-5 reports that only about 45.9% of children received complementary foods at the appropriate age of 6-8 months. Delayed or inadequate complementary feeding is a major contributor to stunting and growth faltering in the second half of infancy.

Key principles of good complementary feeding 🔗

Complementary foods need to be safe, nutritionally adequate, and age-appropriate. They should be prepared and stored hygienically to prevent contamination. Foods should be of the right consistency – starting with semi-solid or pureed textures and gradually progressing to family foods by 12 months. The quantity and frequency of meals should increase as the child grows, while breastfeeding continues to provide a significant portion of nutritional needs.

Minimum acceptable diet (MAD) 🔗

The Minimum Acceptable Diet (MAD) is a composite indicator used to assess the overall adequacy of infant and young child feeding. It combines two sub-indicators: Minimum Dietary Diversity (MDD) and Minimum Meal Frequency (MMF).

Minimum dietary diversity 🔗

MDD measures whether a child consumed foods from at least five or more food groups within a 24-hour period. The standard food groups considered are grains/roots/tubers, legumes/nuts, dairy products, flesh foods (meat, fish, poultry), eggs, vitamin A-rich fruits and vegetables, and other fruits and vegetables. Dietary diversity is a proxy for micronutrient adequacy – children eating from more food groups are more likely to meet their nutrient requirements.

Minimum meal frequency 🔗

MMF varies by the child’s age and breastfeeding status. For breastfed infants aged 6-8 months, the minimum is two meals per day. For breastfed children aged 9-23 months, the minimum increases to three meals per day. For non-breastfed children aged 6-23 months, the requirement is four meals per day, because these children do not receive the additional calories and nutrients from breast milk.

Nationally, the picture is concerning. Only about 11% of Indian children aged 6-23 months receive a minimum acceptable diet. This is one of the lowest rates globally. States like Meghalaya (29%) and Sikkim (24%) perform relatively better, but even their rates highlight the enormous gap that needs to be bridged. This data, reported in NFHS-5, underscores that while breastfeeding practices have improved, complementary feeding quality remains the weakest link in child nutrition in India.

Micronutrient intake and supplementation 🔗

Even when children receive adequate quantities of food, they may still suffer from micronutrient deficiencies – often called “hidden hunger” – if their diets lack variety. Among young children, deficiencies of iron, vitamin A, zinc, iodine, and folic acid are the most common and the most damaging.

Iron deficiency and anaemia 🔗

Iron deficiency is the leading cause of anaemia in children, a condition that impairs cognitive development, physical growth, and immunity. According to NFHS-5, anaemia prevalence among children aged 6-59 months stands at a staggering 67.1%. Only about 21% of children aged 6-23 months consume iron-rich foods regularly, and just 30% of children aged 6-59 months received deworming medication – which helps improve iron absorption – in the six months preceding the NFHS-5 survey. Iron and folic acid supplementation programmes exist under India’s National Health Mission, but coverage and compliance remain inconsistent.

Vitamin A deficiency 🔗

Vitamin A deficiency can lead to xerophthalmia (progressive eye damage that can cause blindness) and severely weakens the immune system, making children more susceptible to infections like measles and diarrhoea. NFHS-5 data indicates that about 47% of children aged 6-23 months consumed vitamin A-rich foods, but only 37% of children aged 6-59 months received vitamin A supplements. The consequences of these deficiencies are significant – vitamin A, iron, and zinc deficiency combined constitute one of the leading risk factors in the global burden of disease.

Strategies to address micronutrient deficiencies 🔗

Addressing micronutrient deficiencies requires a multi-pronged approach. The key strategies include:

Dietary diversification: Encouraging families to include a wider variety of foods in children’s diets – especially locally available fruits, vegetables, legumes, and animal-source foods – is the most sustainable long-term solution. Nutrition education at the community level, delivered through frontline workers at Anganwadi centres, plays a crucial role.

Micronutrient supplementation: Programmatic supplementation of vitamin A (every six months for children 6-59 months), iron-folic acid, and zinc remains a critical intervention. The Indian government’s ICDS and National Health Mission deliver these supplements through Anganwadi centres and health sub-centres, though reaching every eligible child remains a challenge.

Food fortification: Fortifying staple foods like wheat flour, rice, milk, and salt with essential micronutrients (iron, folic acid, vitamin B12, iodine) is increasingly being promoted by the Food Safety and Standards Authority of India (FSSAI) as a cost-effective, population-level intervention.

Deworming: Regular deworming of children reduces intestinal parasitic infections that impair nutrient absorption, particularly of iron. Biannual deworming drives are part of India’s national health strategy, but coverage needs to improve beyond the current 30%.

The road ahead 🔗

Preventing undernutrition in infants and young children is not about a single magic intervention. It requires a continuum of care – starting from delayed cord clamping at birth, through early and exclusive breastfeeding, to timely and diverse complementary feeding, supported by micronutrient supplementation and deworming. Each practice builds on the previous one, and gaps at any stage can have lasting consequences.

India has made progress. Exclusive breastfeeding rates have risen. Institutional deliveries have increased, creating more opportunities for early breastfeeding support. Government programmes like Poshan Abhiyaan and ICDS provide a framework for delivering nutrition services at scale. But the data also reveals persistent gaps – particularly in complementary feeding adequacy and micronutrient supplementation coverage – that demand focused attention, better frontline worker training, and stronger community engagement.

What do you think? Given that only 11% of Indian children receive a minimum acceptable diet, what role can community-level behaviour change – beyond government programmes – play in improving infant feeding practices? And how can families in resource-limited settings be better supported to provide diverse, nutrient-rich complementary foods?
