Washington, May 30 (ANI): Adolescents living in neighborhoods rife with poverty are at an increased risk of getting the sexually transmitted infection (STI) chlamydia in young adulthood, a new research has warned.
Ohio State University researchers analyzed data from a large national study that tracked youths over time. The analysis suggested that children who lived in poor neighborhoods during their teenage years had an almost 25 percent greater risk of having chlamydia in their early 20s - even if they themselves weren't poor - than did teenagers living in wealthier settings.
The effect of living in an impoverished neighborhood on the risk for later infection was unaffected by other known STI risk factors, such as depression, having multiple sex partners or beginning sexual activity at a very young age.
"There is a long-term effect of living in poverty on the risk for sexually transmitted infections in young adulthood, above and beyond behavioral issues," said Jodi Ford, lead author of the study and an assistant professor of nursing at Ohio State. "We have a lot of interventions trying to address sexual risk behaviors, but few target neighborhood poverty and disadvantage. And this work shows that living in a poor neighborhood can have a long-term effect on health."
Ford conducted the research with Christopher Browning, professor of sociology at Ohio State.
Ford and Browning accessed data from the National Longitudinal Study of Adolescent Health (Add Health) to conduct the analysis. The sample they studied included data from three separate interviews of 11,460 youths who participated in the national project. When they were first interviewed, the average age of the children studied was 15.6 years; by the time of the third interview, these same participants were between 18 and 27 years old.
The prevalence of chlamydia among the young adults surveyed was 4.6 percent - relatively low compared to what national data suggest, Ford said. That could be because the national longitudinal study from which she drew her sample took place in schools, meaning it did not capture portions of the population who had dropped out prior to the beginning of the Add Health study.
Chlamydia is a bacterial infection that can affect both men and women, but can cause scarring and infertility issues in women if the infection persists. An estimated 2.86 million infections occur annually, according to the Centers for Disease Control and Prevention, but many are not reported because most people do not have symptoms and do not seek testing.
"Adolescents and young adults are the most likely to experience chlamydia infection in the United States. This study strengthens the evidence that to fully address the sexual health needs of this population, STI prevention efforts should also acknowledge the effects of neighborhood poverty," Ford said.
"This work shows that living in a poor neighborhood can have a long-term effect on health."
The researchers considered four characteristics from U.S. Census data from corresponding years to determine whether the youths lived in poor neighborhoods as teenagers: proportion of households below poverty, proportion of households on public assistance, total unemployment rate and proportion of female-headed households with children.
By applying statistical modeling to the data, Ford determined that young adults who lived in a neighborhood with higher concentrations of poverty during their adolescence had higher odds of testing positive for chlamydia in their early 20s compared to their more advantaged peers.
The study was recently published in the Journal of Urban Health. (ANI)
