“…Assuming optimal birth spacing can improve birth outcomes, 31 recent efforts to increase access to family planning counseling and contraceptive methods in the postpartum period may further reduce the disparities in subsequent pregnancies. 32,33 When examining VPTB, less of the overall disparity could be explained by variables in the models examined in this study (31%). This decrease in the explanatory ability may reflect etiologic differences that distinguish VPTB from moderate-to-late PTB (i.e., 32−36 weeks) or unmeasured factors related to very early delivery.…”

Introduction: Reducing racial/ethnic disparities in preterm birth is a priority for U.S. public health programs. The study objective was to quantify the relative contribution of geographic, sociodemographic, and health determinants to the black, non-Hispanic and white, non-Hispanic preterm birth disparity. Methods: Cross-sectional 2016 U.S. birth certificate data (analyzed in 2018−2019) were used. Black−white differences in covariate distributions and preterm birth and very preterm birth rates were examined. Decomposition methods for nonlinear outcomes based on logistic regression were used to quantify the extent to which black−white differences in covariates contributed to preterm birth and very preterm birth disparities. Results: Covariate differences between black and white women were found within each category of geographic, sociodemographic, and health characteristics. However, not all covariates contributed substantially to the disparity. Close to 38% of the preterm birth and 31% of the very preterm birth disparity could be explained by black−white covariate differences. The largest contributors to the disparity included maternal education (preterm birth, 11.3%; very preterm birth, 9.0%), marital status/paternity acknowledgment (preterm birth, 13.8%; very preterm birth, 14.7%), source of payment for delivery (preterm birth, 6.2%; very preterm birth, 3.2%), and hypertension in pregnancy (preterm birth, 9.9%; very preterm birth, 8.3%). Interpregnancy interval contributed a more sizable contribution to the disparity (preterm birth, 6.2%, very preterm birth, 6.0%) in sensitivity analyses restricted to all nonfirstborn births. Conclusions: These findings demonstrate that the known portion of the disparity in preterm birth is driven by sociodemographic and preconception/prenatal health factors. Public health programs to enhance social support and preconception care, specifically focused on hypertension, may provide an efficient approach for reducing the racial gap in preterm birth.

“…Postpartum contraceptive use has the potential to reduce unintended pregnancy and short inter-pregnancy intervals, both of which may be associated with poorer health outcomes for women and infants (DeFranco, Ehrlich, & Muglia, 2014; Rodriguez, Chang, & Thiel de Bocanegra, 2015; White, Teal, & Potter, 2015). Despite these benefits, postpartum use of highly effective contraception (i.e.…”

Objectives We investigated the prevalence of and sociodemographic associations with receiving prenatal and postpartum contraceptive counseling, including counseling on IUDs and implants. Methods We used data from a prospective cohort study of 803 postpartum women in El Paso and Austin, Texas. We examined prevalence of prenatal and postpartum counseling, provider discouragement of IUDs and implants, and associated sociodemographic characteristics using χ2 tests and logistic regression. Results Half of participants received any prenatal contraceptive counseling, and 13% and 37% received counseling on both IUDs and implants prenatally and postpartum, respectively. Women with more children were more likely to receive any contraceptive counseling prenatally (OR 1.99, p<0.01). Privately-insured women (OR 0.53, p<0.05) had lower odds of receiving prenatal counseling on IUDs and implants than publicly-insured women. Higher education (OR 2.16, p<0.05) and attending a private practice (OR 2.16, p<0.05) were associated with receiving any postpartum counseling. Older age (OR 0.61, p<0.05) was negatively associated with receiving postpartum counseling about IUDs and implants and a family income of $10,000–$19,000 (OR 2.21, p<0.01) was positively associated. Approximately 20% of women receiving prenatal counseling and 10% receiving postpartum counseling on IUDs and implants were discouraged from using them. The most common reason providers restricted use of these methods was inaccurate medical advice. Conclusion Prenatal and postpartum counseling, particularly about IUDs and implants was infrequent and varied by sociodemographics. Practice implications Providers should implement evidenced-based prenatal and postpartum contraceptive counseling to ensure women can make informed choices and access their preferred method of postpartum contraception.

“…El acceso a la anticoncepción principalmente entre la población adolescente, se ha identificado como una de las medidas protectoras contra el parto prematuro. Rodriguez y cols (54), evaluaron el impacto de la cobertura y uso de anticonceptivos dentro de los 18 meses posteriores a un nacimiento en la prevención del parto prematuro. Estos autores encontraron que, dentro de la cohorte evaluada, 9,75% de partos fueron prematuros.…”

RESUMENAntecedentes: La prematuridad es considerada actualmente una prioridad en salud pública para algunos países. Objetivo: Describir la prevalencia del parto prematuro y sus determinantes, en una población de gestantes adolescentes y adultas, que tuvieron su único o último parto en la Fundación Hospital San José de Buga, Colombia, entre los años 2010 a 2015. Métodos. Estudio de casos y controles realizado con 11.881 neonatos mujeres adolescentes y adultas. Los datos fueron analizados en Stata® 11.0, empleando para variables cuantitativas, mediana o promedio y sus medidas de dispersión, comparadas mediante pruebas t, Ranksum, ANOVA o Kruskal Wallis, de acuerdo a su distribución y para variables categóricas; medidas de frecuencia absolutas y relativas, comparadas mediante Pruebas de Chi2 o exacta de Fisher. Para estimar las asociaciones empleamos Odds Ratio con sus intervalos de confianza de 95% y para el análisis multivariado la regresión logística. La significancia estadística fue definida como un valor p<0,05. Resultados. La prevalencia de prematuridad fue 11,4%. Después del análisis multivariado, los determinantes asociados a prematuridad fueron etnia indígena-afrocolombiana o mulato, número de controles prenatales igual o inferior a 6, periodo intergenésico inferior a 2 años, embarazo múltiple, preeclampsia, oligohidramnios, restricción del crecimiento intrauterino y hemorragia del tercer trimestre (incluye desprendimiento prematuro de placenta). Conclusiones. La prematuridad es el resultado de una compleja red de determinantes individuales, sociales, culturales y gestacionales que interactúan, por lo que para su prevención se debe no sólo trabajar en medidas de salud, sino en elaboración de políticas y planes de acción integral.PALABRAS CLAVE: Prematuridad, determinantes de la salud, mujer adolescente, mujer adulta SUMMARY Background: Prematurity is currently considered a public health priority for some countries. Objective: To describe the prevalence of preterm birth and its determinants in a population of adolescent and adult mothers who had their sole or last delivery in the Fundación Hospital San José de Buga, Colombia, between 2010. Methods: Case-control study conducted with 11,881 infants adolescent and adult women. The data were analyzed in Stata 11.0, using quantitative, medium or average and dispersion measures variables compared using t tests, Ranksum, ANOVA or Kruskal Wallis, according to distribution and for categorical variables, frequency measurements absolute and relative, compared with Chi2 tests or Fisher exact. To estimate associations employ odds ratio with confidence intervals of 95% and multivariate analysis logistic regression. Statistical significance was defined as p <0.05. Results: Prematurity prevalence was 11.4%.
