Periconceptional Risk Factors for XXXX among Younger and Older Teen Mothers.

STUDY OBJECTIVES: We sought to determine whether selected periconceptional health behaviors that influence risk for @entity600 differ between older and younger adolescents and whether pregnancy intention predicts more positive preconception health behaviors among teens. DESIGN AND @entity1 : We analyzed interview responses from 954 adolescent control group @entity1 from the National @entity600 Prevention Study who delivered live @entity1 during 1997-2007. MAIN OUTCOME MEASURES: Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated for factors of interest by age categories (13-15, 16-17, and 18 years, relative to 19 years). To construct a composite periconceptional behavior index, we summed the following healthy behaviors: nonsmoker, nondrinker, @entity1501 supplementation, and eating 5 or more servings of fruits and vegetables per day. RESULTS: Analyses indicated that @entity1 in the youngest group (13-15 years of age) were more likely to be Hispanic (aOR 2.83, 95% CI 1.40-5.70) and less likely to engage in some unhealthy pregnancy-related behaviors compared with 19-year-olds, such as smoking (aOR 0.45, 95% CI 0.20-0.99) and being overweight or @entity28 (aOR 0.32, 95% CI 0.16-0.61). However, they were also less likely to have taken periconceptional @entity1501 (aOR 0.44, 95% CI 0.21-0.90). About one-third of teen mothers indicated that their pregnancies had been intended. Among 18- and 19-year-olds, this predicted a higher mean value for the composite periconceptional behavior index (2.30 versus 1.94, P  <= .01). CONCLUSIONS: Teen mothers are not a homogeneous group. Each age subgroup presents varied demographic and behavioral factors that put them at varying levels of risk for @entity600 . Furthermore, caregivers should not assume that teens do not plan pregnancies or that they need not be informed of the importance of periconceptional health.
