Who is having intended births:

1. Who is having intended births: Analysis of two adolescent birth cohorts (2000-2001 and 2010-2011) IsiaRechNzikouPembe and Ann Dozier, RN PhD University of Rochester Department of Public Health Sciences IV. Results • Notable Results from Table 1: • 28.3% fewer births to adolescents over the 10 year period • Compared to 00/01 the 10/11 cohort had fewermothers who were: • Age (12-17); High School graduates; Early prenatal care (1stTrimester) • 10% more adolescents with intended births had a paternity acknowledgement I. Background • US adolescent pregnancy and birth rates declined since 1990s but remain among the highest in the developed world • ~18% of all US pregnancies to adolescents are intended or ambivalent. Some adolescents actively plan their pregnancies and intend to give birth • Perception about benefits of childbearing • Uncertain effectiveness of pregnancy prevention interventions for these adolescents • Notable Results from Table 2: • About 5% fewer intended births over the 10 year period; Significant relationship with birth intention(p< 0.10) included in regression model: II. Purpose • Compare 2 cohorts of adolescent mothers with live births by pregnancy intention to determine: • changes in incidence of intended births • characteristics of those with intended births • differences by intention status within the two cohorts V. Conclusions III. Methods • As with US trends, adolescent births declined; Intended births also declined • Those ages 18-19 and those with Paternity Acknowledgement most likely to have intended births • Maternal education level and birth intention not related aOnlyhospital births. bVariableis missing <10% of its data in the 2000 to 2001 cohort; cVariableis missing <10% of its data in the 2010 to 2011 cohort. dBirthcertificate data from a 9 county region with one primarily urban county. eVariable not collected in the 2000-2001 cohort. fResults in BOLD indicate significant differences ( ≥10% ) amongst both cohorts. • Data Source: Birth registry of all live hospital births in a 9 county region of Upstate New York [one urban; 8 rural]. Data collected post-birth: maternal interviews, prenatal/hospital records • Cohorts: births in 2000-2001 (00/01) and 2010-2011 (10/11) • Inclusion Criteria: mothers 12-19 years of age; no prior live birth • Exclusion Criteria: No response to pregnancy intention question • After applying exclusion criteria: • 2000/01 cohort: 3069 births  2252 births (73.4%) • 2010/11 cohort: 2369 births  1614 births (68.1%) • Dependent Variable: Intention classified as : Notable Results from Table 3: Variables with statistically significant relationship to birth intention (p<.05): VI. Implications • Partner influence and perceived partner desire for pregnancy may contribute to intended pregnancies • Adolescents intending pregnancies might not grasp the full extent of what it means to become parents and often times are under the impression that having a baby will create a stable family unit • Black race and Hispanic ethnicity were significant factors • in the earlier but not the later cohort • Prior pregnancy (or pregnancies) increased the risk • for subsequent pregnancy (especially if the first • pregnancy did not turn out as planned) VII. Limitations • Pregnancy intent was asked in the immediate postpartum period - could bias responses • Secondary data analysis limited to available data (e.g. missing some personal factors, contraceptive use) and missing/incomplete data (e.g. paternal age/education) • Results could be unique to the region in which the study was conducted.
