MALNUTRITION
Malnutrition is a critical public health issue in India, impacting millions of people across the country. It is a complex problem that encompasses a range of nutritional deficiencies and excesses, each with significant health implications. Understanding the types of malnutrition and the importance of addressing this issue is crucial for improving public health outcomes and achieving sustainable development goals.
Malnutrition refers to deficiencies, excesses, or imbalances in a person's intake of energy and nutrients. It encompasses both undernutrition, which includes wasting, stunting, and underweight, and overnutrition, which leads to overweight, obesity, and diet-related non-communicable diseases.

Statistics |
|
Undernutrition |
Wasting |
Low weight for height, indicating recent and severe weight loss due to inadequate food intake or disease. |
According to NFHS-5 2019-21, 19.3% of children under five in India are wasted. |
|
Stunting |
Low height for age due to chronic malnutrition and inadequate nutrition during early stages of growth. |
NFHS-5 reported that 35.5% of children under five in India are stunted. |
|
|
Underweight |
Low weight for age, resulting from both acute and chronic malnutrition. |
NFHS-5 revealed that 32.1% of children under five are underweight in India. |
|
|
Micronutrient Deficiencies |
Iron Deficiency Anaemia |
Reduced oxygen-carrying capacity of the blood due to inadequate iron intake, causing fatigue and impaired cognitive development. |
NFHS-5 indicated that 57% of women aged 15-49 and 67% of children aged 6-59 months in India are anaemic. |
|
Vitamin A Deficiency |
Lack of vitamin A leading to night blindness and increased risk of infectious diseases. |
Global Nutrition Report 2020 estimated that 62% of preschool-aged children in India have subclinical vitamin A deficiency. |
|
|
Iodine Deficiency Disorders |
Insufficient iodine intake causing goitre, hypothyroidism, and developmental disabilities. |
ICMR study found that 12% of the Indian population is at risk of iodine deficiency disorders. |
|
|
Overnutrition |
Overweight and Obesity |
Excessive nutrient and energy intake leading to overweight and obesity, risk factors for various non-communicable diseases. |
NFHS-5 reported that 24% of women and 23% of men in India are overweight or obese. |
|
Diet-Related Non-Communicable Diseases |
Poor dietary habits leading to chronic conditions such as type 2 diabetes, heart disease, and certain cancers. |
Global Burden of Disease Study 2019 identified poor diet as a leading risk factor for premature death and disability in India. |
Addressing malnutrition is essential for achieving optimal health and well-being, promoting economic development, and fulfilling human potential. It has profound implications for individuals, communities, and the nation as a whole.

Impact on Health and Development |
Child Mortality and Morbidity: Malnutrition is a leading cause of child mortality, contributing to approximately 45% of all child deaths globally. In India, malnourished children are at higher risk of infections, stunted growth, and developmental delays. |
A study published in The Lancet found that improving nutrition could prevent up to 68% of child deaths in India. |
|
Cognitive Development: Nutritional deficiencies during critical periods of growth can impair cognitive development, affecting learning, memory, and academic performance. |
Research by UNICEF has shown that malnourished children score lower on cognitive tests and have poorer educational outcomes. |
|
|
Maternal Health: Malnutrition in women, especially during pregnancy, leads to poor maternal health and increases the risk of complications such as anaemia, preterm birth, and low birth weight. |
The NFHS-5 reported that 52% of pregnant women in India are anaemic, highlighting the need for nutritional interventions to improve maternal health. |
|
|
Economic Consequences |
Productivity Loss: Malnutrition reduces productivity by impairing physical and cognitive abilities, leading to lower work capacity and economic output. |
The World Bank estimates that malnutrition costs India 2-3% of its GDP annually due to lost productivity and increased healthcare expenses. |
|
Healthcare Costs: Malnutrition increases the burden on healthcare systems by contributing to the prevalence of diseases and conditions that require medical attention and treatment. |
Treating nutrition-related diseases like diabetes and heart disease accounts for a significant portion of India's healthcare expenditure. |
|
|
Social and Human Development |
Educational Attainment: Malnutrition negatively impacts educational attainment, reducing opportunities for children to reach their full potential and contribute to society. |
Studies have shown that stunted children are 19% less likely to be able to read by age 8 compared to their well-nourished peers. |
|
Intergenerational Effects: Malnutrition can perpetuate a cycle of poverty and poor health across generations, as malnourished mothers are more likely to have malnourished children. |
The National Institute of Nutrition (NIN) reported that children born to malnourished mothers are 2.5 times more likely to suffer from stunting. |
|
|
Achieving Sustainable Development Goals (SDGs) |
SDG 2 (Zero Hunger): Addressing malnutrition is essential for achieving SDG 2, which aims to end hunger and ensure access to nutritious food for all. |
The UN's State of Food Security and Nutrition report emphasizes that tackling malnutrition is crucial for achieving food security and improving global health outcomes. |
|
SDG 3 (Good Health and Well-being): Malnutrition directly impacts health and well-being, hindering progress towards SDG 3, which focuses on ensuring healthy lives for all. |
Efforts to reduce malnutrition can contribute to a decline in preventable deaths and an increase in life expectancy. |
