Hunger and Anaemia: How Malnutrition Limits a Girl's Life
Malnutrition rarely announces itself. It looks like a girl who is always tired, who cannot concentrate in class, who catches every infection, or who reaches her teens far shorter than she should. It is not only a shortage of food. It is a consequence of poverty, unequal feeding within households, and health systems that reach girls too late.
Part 4 of 10 in our series on the consequences of poverty and inequality on girls and women. Series overview · All articles.
What the evidence says
The World Health Organization estimates that about 30% of women aged 15 to 49 worldwide are anaemic, roughly 571 million women and girls. Anaemia reduces oxygen delivery to the brain and muscles, which lowers concentration, stamina and school performance, and increases the risk of complications in pregnancy and childbirth.
Stunting tells a similar story. UNICEF, WHO and the World Bank estimate that around 148 million children under five are stunted, a marker of chronic undernutrition that is linked to poorer cognitive development and lower lifetime earnings. These are not rare conditions in poor communities; they are the norm where food is scarce, diets are monotonous and girls are fed last.
How poverty and inequality drive it
Poverty limits both the quantity and the variety of food. When a household eats mostly cereals and little else, girls may get enough calories to survive but not enough iron, protein, iodine or vitamin A to thrive. Son preference adds a second layer: in some families, boys are served first and girls receive smaller portions or less nutritious food.
Other pressures compound the deficit. Early marriage and adolescent pregnancy increase a girl's nutritional needs at the very moment her body is still growing. Menstruation, especially where sanitary products are unavailable or taboo, adds blood loss. Repeated infections and poor sanitation cause further losses. Each factor is manageable on its own; together they produce a girl who is permanently depleted.
What it does to a girl's life
Iron-deficiency anaemia reduces attention, memory and physical endurance, so a girl who is anaemic learns less even when she attends school. Stunting and wasting increase the risk of illness, and repeated illness increases absence. A girl who misses school because she is sick, or who is too tired to study, is more likely to fall behind and leave.
The damage extends into adulthood. Anaemic women are more likely to have low-birth-weight babies, and low-birth-weight girls are more likely to become stunted mothers. That is how malnutrition becomes intergenerational: not through genetics, but through poverty repeating the same conditions in each generation.
The economic cost is easy to miss because it is spread across a lifetime. A girl who is anaemic misses more school days, scores lower on tests and is less likely to complete secondary education. Each of those losses reduces her future earnings, and the reduction is largest for girls who were already poor. Nutrition is therefore not a welfare line item; it is an investment in the productivity of the next generation. The return is highest when the intervention reaches girls before adolescence, and again during it.
In India
NFHS-5 found that 57% of women aged 15 to 49 were anaemic, and 35.5% of children under five were stunted. India has some of the world's largest nutrition programmes, including school meals, iron and folic acid supplementation, deworming and the Anganwadi system, yet coverage and quality vary widely between states and districts.
CRY has highlighted how drought, migration and food insecurity worsen child malnutrition, and how girls in poor households are often the last to be fed. The lesson from states that have improved is consistent: it takes more than a food programme. It takes clean water, sanitation, nutrition counselling for families, and a school that provides a reliable meal.
What changes it
The evidence supports a package rather than a single fix: school meals that are actually eaten, iron and folic acid supplementation with deworming, nutrition counselling for adolescent girls and mothers, cash transfers that raise household food spending, and water and sanitation that reduce infection. Fortified foods and dietary diversity matter too, especially in the first 1,000 days and during adolescence.
Timing is critical. The first 1,000 days shape a child's future, but adolescence is the second window: a girl who is well nourished at 12 is more likely to finish school, avoid early pregnancy and enter adulthood healthy. Investing in that window is one of the highest-return interventions available.
What Sneha Karma Foundation does
Our Support-A-Girl programme includes meals, healthcare and mentoring alongside school costs, so a girl is fed and well enough to learn. Our Community Wellbeing work supports families and communities on health and nutrition.

Frequently asked questions
In poor households, girls are often fed last and less. Early marriage and pregnancy increase their needs, and menstruation adds iron loss. The result is a higher burden of anaemia and stunting.
Tiredness, breathlessness, pale skin, dizziness and poor concentration are common. Diagnosis needs a blood test, and treatment is usually simple iron supplementation.
Yes, especially in adolescence. Better diets, supplementation, deworming and treatment of infection can restore health and improve school performance.
You can sponsor a girl, which covers meals and healthcare alongside school costs, or give to the programme.
