This study explored the differences between African American and Latina female adolescents who desire to become pregnant and those who do not. Five hundred and thirty-one sexually experienced, never pregnant adolescents completed surveys containing questions about demographics, sexual behavior and contraceptive use, sexual and contraceptive behavioral intentions, attitudes toward condoms and birth control, substance use, quality of mother-daughter relationship, and mother-daughter communication about sexual issues. Medical and self-report data regarding pregnancies in the subsequent 6 months was also obtained. Adolescents who desired pregnancy had sex more frequently, engaged in more unproteccted sex, and became pregnant in the following 6 months at a higher rate. They were significantly more likely to have poor relationships with their mothers, fewer siblings, and higher rates of substance use. The results suggest the importance of a family systems approach to studying intentional teenage pregnancy. (Author)
