New research shows teenagers are less likely to become parents before the age of 18 if they have strong family and community ties.
Public health researchers analyzed data collected from more than 9,000 American high school students. Follow-up surveys continued through their early 20s, looking at “social determinants” such as family structure and education.
Julie Baldwin, professor of health sciences at Northern Arizona University, coauthored the study.
“Feeling close to others in school, living in a two-parent home, and participation in volunteering or community service were all associated with a reduced chance of pregnancy,” she said.
Finishing high school and enrolling in college also led to lower pregnancy rates.
The study’s lead author, Sarah Maness of the University of Oklahoma , said these social factors often are overlooked in programs designed to prevent teen pregnancy. Programs tend to focus on at-risk groups such as Hispanics and African-Americans, which have twice the teen pregnancy rates of whites.
“One of the reasons for using a social determinants approach is to look beyond race, ethnicity or geographic area to see what are these underlying factors that could be the true causes or true associations with adolescent pregnancy," Maness said.
Teen pregnancies have dropped by at least 50 percent nationwide over the last two decades, according to the Centers for Disease Control and Prevention. But Arizona’s rate remains higher than the national average, at nearly 4 percent.
