Researchers extensively tested almost 3 000 school children of mothers who had participated in an earlier study into the effects of consuming supplements during pregnancy.
They found that the children whose mothers took multiple micronutrient (MMN) supplements during pregnancy had better 'procedural memory', equivalent to the score typical after an additional half-year of schooling, than the children whose moms had only taken iron-folic acid (IFA) supplements.
Happy moms and educated parents
Taking a good supplement during pregnancy is important, but there are more ways to ensure smart kids.
According to the research, socio-environmental factors – like happy moms and nurturing home environments - are strongly linked to children's cognitive ability.
From declarative memory, procedural memory, executive function, academic achievement and fine motor dexterity to socio-emotional health, a child's nurturing environment is strongly correlated to brain development and general intellectual ability.
In fact, researchers were surprised that biological factors, like low infant birth weight, were not as strongly linked to cognitive ability as the socio-environmental factors, like home environment and parents’ education.
