About 1,000 Days [1]

1,000 Days promotes targeted action and investment to improve nutrition for mothers and young children during the critical 1,000 days from pregnancy to age 2, when better nutrition can have a lifelong impact on a child’s future and help break the cycle of poverty.

The organisation’s vision is to inspire a global movement that will result in nourished, healthier, more productive futures for all children, their families and societies across the world.

How 1,000 Days works:
1,000 Days is an advocacy hub that champions new investment and partnerships to improve nutrition during the critical 1,000 days between a woman’s pregnancy and a child’s 2nd birthday as a way to achieve long-term progress in global health and development.

1,000 Days champions nutrition within the U.S. business, government, and civil society communities and promotes action and investment in early nutrition by:

  • Communicating the importance of the 1,000-day window for impact;
  • Advocating for greater action and investment in maternal and child nutrition; and
  • Catalyzing partnerships among different sectors to scale up efforts to reduce malnutrition.

In order to accelerate global action and investment to address the crisis of maternal and child undernutrition, U.S. Secretary of State Hillary Rodham Clinton, then-Irish Minister for Foreign Affairs Micheál Martin and a community of global leaders launched the 1,000 Days Partnership in September 2010.

To support the 1,000 Days Partnership and the global SUN movement, a U.S.-based hub was formed in June 2011, by InterAction, a coalition of U.S.-based international relief and development organizations, and the Global Alliance for Improved Nutrition (GAIN) in collaboration with the U.S. Department of State. As a hub, 1000 Days helps focus attention on the 1,000 day window of opportunity for impact, engage the private sector, civil society, and government in the U.S. in efforts to improve maternal and young child nutrition throughout the world, and promote partnerships across these sectors to achieve a scale change in improving nutrition.


The 1,000 days between a woman’s pregnancy and her child’s 2nd birthday offer a unique window of opportunity to shape healthier and more prosperous futures. The right nutrition during this 1,000 day window can have a life-changing impact on a child’s ability to grow, learn, and rise out of poverty—providing the foundation for long-term economic growth and stability.

Good nutrition is essential for growth, yet poor nutrition is pervasive

Malnutrition is one of the world’s most insidious, yet least addressed, health and development challenges. Globally, it contributes to almost half of all deaths of young children. Close to 200 million children suffer from chronic nutritional deprivation that leaves them permanently stunted—unable to fulfill their genetic potential to grow and thrive—and keeps families, communities, and countries locked in a cycle of hunger and poverty.
The impact of malnutrition during the critical 1,000 days between a woman’s pregnancy and a child’s 2nd birthday last a lifetime. Malnutrition early in life can cause irreversible damage to a child’s brain development, immune system, and physical growth. This can result in a diminished capacity to learn, poorer performance in school, greater susceptibility to infection and disease, and a lifetime of lost earning potential. The damage done by malnutrition translates into a huge economic burden for countries, with billions of dollars lost in productivity and avoidable health care costs.

Nutrition is the most cost-effective investment to drive global health and prosperity

Research has shown that $1 invested in nutrition generates as much as $138 in economic benefit. Yet despite the extraordinary returns on investment, the world spends less than 1% on life-saving, basic nutrition solutions that have been proven to work.

Focusing on improving nutrition during the 1,000 day window can:

  • Save millions of lives each year.
  • Reduce the human suffering and economic strain caused by infectious diseases such as HIV/AIDS, chronic diseases such as diabetes, and obesity.
  • Build self-sufficiency—well-nourished children grow up to earn up to 46% more over their lifetimes
  • Boost a country’s GDP by as much as 11% annually.
  • Help break the cycle of hunger and poverty
