Accumulated scientific evidence shows that proper nutrition and stimulation in utero and during early childhood benefit physical and mental well-being later in life and contribute to the development of children’s cognitive and socioemotional skills. Yet, a critical but often overlooked fact in policy design and program development across the world is the association between maternal depression and childhood stunting -- the impaired growth and development measured by low height-for-age.
In 2000, one in three Peruvian children under 5-years-old suffered from chronic malnutrition. Several years later despite high economic growth and hundreds of millions of dollars spent in nutrition programs, the stunting rate barely inched down. Then, something happened.
