Children who grow up poor and underprivileged experience a variety of health problems at higher rates than the general population. It suggests that giving families as little as 14 hours of training aimed at improving parental nurturing can significantly reduce a child’s long-term inflammation levels — a known risk factor for a variety of health problems, including diabetes, coronary heart disease and stroke. Then, the researchers provided 173 of the mother-child pairs with 14 hours — or 7 weeks — of parental training when their children turned 11. Eight years later, the scientists took samples of the teenagers blood to determine their levels of inflammation.
