Racial Disparity, Depression, and Birth Outcomes Among Pregnant Teens.

Objectives To examine the risk of premature delivery (PD) and small for gestational age (SGA) among pregnant teens with depressive disorders (DD), and the impact of race/ethnicity on these birth outcomes. Design/Methods We examined the hospital discharge records of pregnant mothers between the age of 13-18 year old who gave birth in the years 1994, 2000, 2006, and 2012 in the National Inpatient Sample database. We calculated the risk for PD and SGA among pregnant teens with and without DD in the overall population and within each race/ethnicity. Results Weighted sample included 1,023,586 pregnant teenage women. Prevalence of DD among teens was 0.93%, with a significantly increasing trend from 0.29% in 1994 to 2.01% in 2012 (p < 0.001). Declining trend was observed in the proportion of pregnant younger teens from 1994 to 2012. Prevalence of depression among teenage mothers was highest among Caucasians compared to other races. Prevalence of SGA among pregnant teens was 2.23% that significantly increased from 1.63% in 1994 to 3.44% in 2012 (p < 0.001). African American teens with DD had decreased risk for PD compared to AA without DD (OR 0.70; CI 0.57 - 0.387, p < 0.001). Hispanic teens with DD had increased risk for SGA compared to Hispanics without DD (adjusted OR 1.53; CI 1.10-2.13, p < 0.001). Conclusions for Practice There is an increasing trend for diagnosing DD among pregnant teens. Less young teenage girls are giving birth in recent years. The impact of DD on PD and SGA differs according to race. More studies are warranted to examine underlining factors responsible for these findings.
