A new Iowa State study of nearly 1,000 low-income families in three major cities found that one in four children between the ages of 11 and 16 reported having sex, with their first sexual intercourse experience occurring at the average age of 12.77. The study was co-authored by Brenda Lohman, an associate professor of human development and family studies; and Tina Jordahl, a former ISU graduate student. Tina Jordahl, a former Iowa State HDFS and public policy graduate student who is now a market research specialist with Hospice of Central Iowa, collaborated with Lohman on the study. It analyzes data from the “Welfare, Children and Families: A Three-City Study” — a six-year longitudinal investigation of low-income families living in Boston, Chicago and San Antonio.
