A Population-Based Study of Factors Associated with Postpartum Contraceptive Use by Birth Interval Length.

OBJECTIVE: The purpose of this study was to evaluate factors associated with postpartum contraceptive use among women with short and moderate-to-long birth intervals using population-based data from the Pregnancy Risk Assessment and Monitoring System. METHODS: Because only Mississippi and Tennessee include a question about birth interval length on their Pregnancy Risk Assessment and Monitoring System survey, this analysis was limited to women from those states who reported information on this variable (N = 2198). Demographic, lifestyle, and reproductive data, including information on postpartum contraceptive use, were obtained from surveys and birth certificates. Logistic regression was used to obtain odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Nearly 90% of women reported currently using a form of contraception during the postpartum period. In the unadjusted model, among women with short birth intervals, there was no association between alcohol consumption during pregnancy and postpartum contraceptive use (OR 1.03, 95% CI 0.15-7.31); however, smoking during pregnancy was associated with a decreased odds of postpartum contraceptive use (OR 0.70, 95% CI 0.25-1.96). Among women with moderate-to-long birth intervals, alcohol use during pregnancy was associated with a decreased odds (OR 0.71, 95% CI 0.28-1.80) and smoking during pregnancy was associated with an increased odds (OR 1.18, 95% CI 0.60-2.30) of postpartum contraceptive use. Regardless of birth interval length, women with no health insurance had a decreased odds of postpartum contraceptive use when compared with women with health insurance (short birth interval: OR 0.89, 95% CI 0.32-2.49 and moderate-to-long birth interval: OR 0.85, 95% CI 0.52-1.39). Among women with short birth intervals, non-Hispanic black women had a decreased odds of postpartum contraceptive use (OR 0.14, 95% CI 0.03-0.64) and women who were unmarried or had a history of preterm delivery had an increased odds of postpartum contraceptive use (unmarried: OR 5.81, 95% CI 1.26-26.69 and preterm delivery: OR 4.19, 95% CI 1.42-12.37, respectively) after adjustment for confounders. Among women with moderate-to-long birth intervals, individuals who identified as Hispanic/mixed race/other had a statistically significant decreased odds of postpartum contraceptive use after adjustment (OR 0.43, 95% CI 0.18-0.99). CONCLUSIONS: Findings underscore the importance of postpartum medical visits for all women, regardless of birth interval length. Certain groups of women may need additional counseling regarding the importance of using contraceptives to prevent another closely spaced or unintended pregnancy.

Factors Associated with Preventive Dental Visits Before and During Pregnancy.

Objective: Poor prenatal oral health has implications for maternal, fetal, and infant health. Studies have shown an association between periodontal disease and adverse pregnancy outcomes, such as preterm delivery, low birth weight, and pre-eclampsia. The objective of this study was to identify the factors associated with preventive dental visits before and during pregnancy and examine the relationship of dental insurance with those visits among Virginia women. Methods: The Virginia Pregnancy Risk Assessment Monitoring System (2012-2014) cross-sectional data were used to explore the use of dental cleaning visit among women. The bivariate and multivariate analyses included sociodemographic variables, health risk factors, chronic conditions, oral health knowledge, and oral health promotion variables. All estimates were weighted; p < 0.05 was considered statistically significant. Results: A total of 1,344 weighted respondents represented ∼293,608 women in Virginia. Overall, 56% of women reported a before pregnancy dental cleaning visit, and 47% of women reported a during pregnancy dental cleaning visit. Nearly 60% of women were non-Hispanic white, 78% were between 20 and 34 years of age, and 67% reported having dental insurance. Dental insurance (odds ratio [OR] = 3.5; 95% confidence interval [95% CI] = 2.17-5.67) and oral health knowledge (OR = 2.8; 95% CI = 1.42-5.48) were associated with before pregnancy dental visit. During pregnancy dental visit was strongly associated with dental insurance (OR = 5.8; 95% CI = 2.80-11.97), before pregnancy dental visit (OR = 20.72, 95% CI = 11.14-38.54), and oral health promotion by health provider (OR = 12.37, 95% CI = 7.31-20.93). Conclusions: Overall, the use of a preventive dental visit before and during pregnancy was low among Virginia women. Improving the use of routine dental visits before pregnancy, increasing access to dental insurance, and engaging health care providers to promote oral health can impact the use of dental care during pregnancy.

Interbirth Interval and Pregnancy Complications and Outcomes: Findings from the Pregnancy Risk Assessment Monitoring System.

INTRODUCTION: Although the definition of a short interbirth interval has been inconsistent in the literature, Healthy People 2020 recommends that women wait at least 18 months after a live birth before attempting their next pregnancy. In the United States, approximately 33% of pregnancies are conceived within 18 months of a previous birth. Pregnancies that result from short interbirth intervals can pose serious risks. The objective of this study was to determine the association between interbirth interval and understudied pregnancy complications and outcomes, including small for gestational age (SGA) infants, premature rupture of membranes (PROM), preterm PROM (PPROM), placenta previa, and gestational diabetes, using Pregnancy Risk Assessment and Monitoring System data from Mississippi and Tennessee. METHODS: This study collected self-reported information from 2212 women on interbirth interval (≤18 months, ie, short; 19-35 months, ie, intermediate; and ≥36 months, ie, long; referent), PPROM, placenta previa, and gestational diabetes. SGA and PROM data were obtained from birth certificates. Logistic regression was used to calculate odds ratios (ORs) and 95% CIs. RESULTS: After adjustment, there were no strong associations between interbirth interval and PPROM, gestational diabetes, or SGA infants. However, women with shorter intervals had increased odds of PROM (short: OR, 3.54; 95% CI, 1.22-10.23 and intermediate: OR, 4.09; 95% CI, 1.28-13.03) and placenta previa (short: OR, 2.58; 95% CI, 1.10-6.05 and intermediate: OR, 1.69; 95% CI, 0.94-3.05). DISCUSSION: The study's findings provide further support for encouraging women to space their pregnancies appropriately. Moreover, findings underscore the need to provide women with family planning services so that closely spaced pregnancies and unintended pregnancies can be avoided. Additional studies of the role of interbirth interval on these understudied pregnancy complications and outcomes are warranted.

Factors associated with pregnancy intention among women who have experienced a short birth interval: findings from the 2009 to 2011 Mississippi and 2009 Tennessee Pregnancy Risk Assessment Monitoring System.

PURPOSE: One-third of all pregnancies in the United States are conceived within 18 months of a prior live birth. Preventing unintended pregnancies may help to decrease the prevalence of pregnancies with these short interpregnancy intervals. However, data on factors associated with pregnancy intention among women who have had short birth intervals are sparse. Pregnancy Risk Assessment Monitoring System data were used to further evaluate these associations. METHODS: Because only Mississippi and Tennessee Pregnancy Risk Assessment Monitoring System include a survey question about birth interval length, this analysis was limited to women from those states who recently had a short birth interval (n = 384). Pregnancy intention and demographic, lifestyle, and reproductive data were obtained from surveys and birth certificates. Logistic regression was used to obtain odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Nearly 76% of women with short birth intervals reported their pregnancy as unintended. Women who were non-Hispanic black or consumed alcohol during pregnancy had statistically significant increased odds of reporting the pregnancy with a short birth interval as being unintended (OR = 3.98; 95% CI: 1.73-9.16 and OR = 10.56; 95% CI: 1.80-61.83, respectively). CONCLUSIONS: Although all women should be counseled on postpartum contraceptive use, findings suggest that important subpopulations of women may benefit from more targeted counseling during prenatal care visits and the immediate postpartum hospital stay regarding the importance of using contraception to not only better space pregnancies but also prevent unintended pregnancies.

The Association Between Maternal Depression During Pregnancy and Adverse Birth Outcomes: A Retrospective Cohort Study of PRAMS Participants.

Women of reproductive age are at higher risk for depression than men; and depressive behaviors and endocrine imbalances could lead to adverse birth outcomes. The purpose of this study was to investigate whether maternal depression during pregnancy affected adverse birth outcomes, specifically preterm birth and small for gestational age (SGA). This study included 4123 women who participated in the 2009-2011 Utah Pregnancy Risk Assessment Monitoring System, an ongoing surveillance project that investigates maternal behaviors in women who have recently had a live birth. Women self-reported information on depression and outcome data were obtained from birth certificates. Logistic regression was used to obtain odds ratios (ORs) and 95% confidence intervals (CIs). Women who self-reported a diagnosis of depression during pregnancy had statistically significant increased odds of preterm birth as compared to women who had not been diagnosed with depression (OR 1.51; 95% CI 1.07, 2.12); there was no association between depression and SGA (OR 0.92; 95% CI 0.63, 1.34). After adjustment for prenatal care visits, the depression-preterm birth association was attenuated and no longer statistically significant (OR 1.29; 95% CI 0.90, 1.85). After adjustment for smoking, there continued to be no strong association between depression and SGA (OR 0.80; 95% CI 0.54, 1.20). The findings of this study do not support a maternal depression-adverse birth outcomes relationship among a predominantly healthy population of non-Hispanic White, well educated women. Future studies should focus on other diverse populations of women to determine if there is an association for these subgroups.

Clinical inquiries. What interventions can help patients stop using chewing tobacco?

Nicotine replacement therapy (NRT), including gum and patches, decreases cravings and short-term abstinence rates, but does not improve long-term abstinence (strength of recommendation [SOR]: B, meta-analysis of small randomized controlled studies [RCT]). It is unclear if bupropion has an effect on cessation rates (SOR: B, small RCTs with conflicting results). Behavioral interventions increase abstinence rates for smokeless tobacco users (SOR: B, meta-analysis of small RCTs).
