The stress of growing up poor can hurt a childs brain development starting before birth, research suggests and even very small differences in income can have major effects on the brain.
Researchers have long suspected that childrens behaviour and cognitive abilities are linked to their socioeconomic status, particularly for those who are very poor. The reasons have never been clear, although stressful home environments, poor nutrition, exposure to industrial chemicals such as lead and lack of access to good education are often cited as possible factors.
In the largest study of its kind, published on 30 March in Nature Neuroscience1, a team led by neuroscientists Kimberly Noble from Columbia University in New York City and Elizabeth Sowell from Children's Hospital Los Angeles, California, looked into the biological underpinnings of these effects. They imaged the brains of 1,099 children, adolescents and young adults in several US cities. Because people with lower incomes in the United States are more likely to be from minority ethnic groups, the team mapped each childs genetic ancestry and then adjusted the calculations so that the effects of poverty would not be skewed by the small differences in brain structure between ethnic groups...... more

Still, the researchers are hopeful that the impacts could be reversible through interventions such as providing better child care and nutrition. Research in humans and in other animals suggests that is the case: a study in Mexico, for instance, showed that supplementing poor families' income improved their children's cognitive and language skills within 18 months

(70,088 posts)and feed these kids.
have an afterschool meal. or they should do the backpack meal at the end of the day.
let young children have constant access to food.
primary grades should have their own fridge in each classroom w fruit, veggies and milk for kids to snack on as they wish.
feed them with fresh foods served w love.
this will save lives.
sometimes i wonder how we get the little things so wrong. the little things that are really big things, i mean.
