When a child is conceived may affect intelligence down the road, according to new research at Indiana University.Dr. Paul Winchester studied more than 1.6 million Indiana school children who took a statewide standardized exam known as ISTEP.He reported that math and language scores were seasonal. Children conceived in June through August scored the lowest.
Winchester theorized that the finding was because pesticide levels are highest in fields and water during those months. In other research presented Monday, Winchester said that those chemicals are also linked to pre-term births."While our findings do not represent absolute proof that pesticides and nitrates contribute to lower ISTEP scores, they strongly support such a hypothesis," he said.
