Washington – A new study, that has been published in the journal Nature Communication, says with the help of generous anti-poverty programmes, the mental development void between kids of rich and poor households may be narrowed down. The study, supported by the National Institute on Drug Abuse at the National Institutes of Health, used the data of 10,000 children from 9 to 11 years from 17 states. Study authors said: “Structural policy interventions may be an effective strategy for reducing these disparities.”
