Association of Medicaid Expansion With Access to Abortion Services for Women With Low Incomes in Oregon

BackgroundThe Affordable Care Act allowed states to expand Medicaid eligibility for women with low incomes before pregnancy. Women who experience an unintended pregnancy may encounter fewer delays in accessing abortion services if they are already enrolled in Medicaid. In states where the Medicaid program includes coverage for abortion services, Medicaid expansion may increase timely access to abortion services. Oregon has expanded Medicaid and is 1 of 16 states in which the Medicaid program covers abortion services. We explored how Medicaid expansion in Oregon was associated with Medicaid-financed abortion rates and receipt of medication abortion relative to surgical abortion.MethodsUsing Medicaid claims and eligibility data we identified women ages 19 to 43 (n = 30,367) who had abortions before the expansion period (2008–2013) and after the expansion period (2014–2016). We used American Community Survey data to estimate the annual number of Oregon women aged 19 to 43 with incomes below 185% of the federal poverty level who would be eligible for a Medicaid-financed abortion. We conducted interrupted time series analyses using negative binomial and logistic regression models.ResultsIncidence of Medicaid-financed abortion increased from 13.4 in 1,000 women in 2008 to 16.3 in 2016. Medication abortion receipt increased from 11.5% of abortions in 2008 to 31.7% in 2016. For both outcomes, we identified an increasing time trend after Medicaid expansion, followed by a subsequent leveling off of the trend. By the end of 2016, incidence of Medicaid-financed abortion was 4.5 abortions per 1,000 women-years (95% confidence interval, 3.3–5.7) higher than it would have been without expansion and medication abortions comprised a 7.4 percentage point (95% confidence interval, 4.4–10.4) greater share of all abortions.ConclusionsMedicaid expansion was associated with increased receipt of Medicaid-financed abortions and may have reduced out-of-pocket payment among women with low incomes. Increased receipt of medication abortion may indicate that expansion enhanced earlier access to services, possibly as a result of increased prepregnancy Medicaid enrollment, and this earlier access may increase reproductive autonomy and safety.     

Postpartum Transition of Care: Racial/Ethnic Gaps in Veterans’ Re-Engagement in VA Primary Care after Pregnancy

IntroductionPregnancy presents an opportunity to engage veterans in health care. Guidelines recommend primary care follow-up in the year postpartum, but loss to follow-up is common, poorly quantified, and especially important for those with gestational diabetes (GDM) and hypertension. Racial maternal inequities are well-documented and might be exacerbated by differential postpartum care. This study explores variation in postpartum re-engagement in U.S. Department of Veteran Affairs health care system (VA) primary care to identify potential racial/ethnic inequities in this care transition.MethodsWe conducted a complete case analysis of the 2005–2014 national VA birth cohort (n = 18,414), and subcohorts of veterans with GDM (n = 1,253) and hypertensive disorders of pregnancy (HDP; n = 2,052) using VA-reimbursed discharge claims and outpatient data. Outcomes included incidence of any VA primary care visit in the postpartum year; in age-adjusted logistic regression, we explored race/ethnicity as a primary predictor.ResultsIn the year after a VA-covered birth, the proportion of veterans with one or more primary care visit was 53.8% overall, and slightly higher in the GDM (56.0%) and HDP (57.4%) subcohorts. In adjusted models, the odds of VA primary care follow-up were significantly lower for Black/African American (odds ratio, 0.87; 95% confidence interval, 0.81–0.93), Asian (odds ratio, 0.76; 95% confidence interval, 0.61–0.95), and Hawaiian/other Pacific Islander (odds ratio, 0.73; 95% confidence interval, 0.55–0.96) veterans, compared with White veterans. Among the subcohorts with GDM or HDP, there were no significant associations between primary care and race/ethnicity.ConclusionsOne-half of veterans re-engage in VA primary care after childbirth, with significant racial differences in this care transition. Re-engagement for those with the common pregnancy complications of HDP and GDM is only slightly higher, and less than 60%. The potential for innovations such as VA maternity care coordinators to address such gaps merits attention.     

Nutritional risk factors of early development of postpartum prediabetes and diabetes in women with gestational diabetes mellitus

ObjectiveEarly detection of prediabetes and diabetes after delivery helps prevent and delay the development of overt type 2 diabetes in women with gestational diabetes mellitus (GDM). We sought to identify modifiable risk factors for the early development of postpartum type 2 diabetes in women with GDM that may help establish interventions for preventing or delaying the subsequent onset of type 2 diabetes.MethodsThree hundred eighty-one women who developed GDM during pregnancy were tested for 1) antepartum anthropometric and biochemical measurements, 2) pregnancy outcome, 3) oral glucose tolerance test at 6 to 12 wk after delivery, and 4) postpartum anthropometric, biochemical, and nutritional measurements. The subjects were divided into three groups on the basis of the postpartum oral glucose tolerance test results: normal glucose tolerance group (n = 193), prediabetes (n = 161), and diabetes (n = 27).ResultsThe incidences of postpartum prediabetes and diabetes at 6 to 12 wk follow-up in Korean women with GDM were 44.8% and 5.2%, respectively. Antepartum modifiable risk factors for developing type 2 diabetes at early postpartum included higher body mass index, lower β-cell function, insulin dosage during late pregnancy, and the non-modifiable risk factor of family history of diabetes (R² = 0.14). Postpartum risk factors included higher body mass index, serum triacylglycerols, hemoglobin A_1c, and energy intake and lower insulin secretion capacity (R² = 0.43). Animal fat intake was higher in the prediabetes and diabetes groups than in the normal glucose tolerance group, whereas breast-feeding did not alter the risk for the development of postpartum diabetes.ConclusionThis study strongly suggests that the development of postpartum type 2 diabetes in women with GDM can be prevented and/or delayed by lifestyle and nutritional intervention during antepartum and postpartum.     

How does gestational diabetes affect postpartum contraception in nondiabetic primiparous women?

Background

The aim of the study is to explore the effect of gestational diabetes mellitus (GDM) on postpartum contraception among nondiabetic primiparous women.

Study Design

Secondary analyses of 2004-2005 Pregnancy Risk Assessment Monitoring System data from Michigan and Oregon.

Methods

Analyses were performed on 2332 women, taking complex survey design into consideration. Crude and adjusted odds ratios (cOR; aOR) and their 95% confidence intervals (CI) were obtained using logistic regression analyses.

Results

Postpartum use of hormonal (aOR=1.12, 95% CI: 0.68-1.83) and nonhormonal (aOR=1.18, 95% CI: 0.73-1.92) contraception were not influenced by GDM after controlling for confounders. Female sterilization was more frequently adopted (cOR=4.99, 95% CI: 1.13-22.17) and depomedroxyprogesterone acetate (DMPA) (cOR=0.53, 95% CI: 0.23-1.18), diaphragm/cervical cap/sponge (cOR=0.13, 95% CI: 0.016-0.95) and cervical ring (cOR=0.13, 95% CI: 0.017-0.98) were less frequently adopted by women reporting GDM diagnosis.

Conclusion

With few exceptions, GDM does not appear to affect postpartum hormonal and nonhormonal contraception.     

Interrupting the Pathway from Gestational Diabetes Mellitus to Type 2 Diabetes: The Role of Primary Care

ObjectiveOur objective was to describe patient-, provider-, and health systems-level factors associated with likelihood of obtaining guideline-recommended follow-up to prevent or mitigate early-onset type 2 diabetes after a birth complicated by gestational diabetes mellitus (GDM).MethodsThis study presents a retrospective cohort analysis of de-identified demographic and health care system characteristics, and clinical claims data for 12,622 women with GDM who were continuously enrolled in a large, national U.S. health plan from January 31, 2006, to September 30, 2012. Data were obtained from the OptumLabs Data Warehouse. We extracted 1) known predictors of follow-up (age, race, education, comorbidities, GDM severity); 2) novel factors that had potential as predictors (prepregnancy use of preventive measures and primary care, delivery hospital size); and 3) outcome variables (glucose testing within 1 and 3 years and primary care visit within 3 years after delivery).ResultsAsian ethnicity, higher education, GDM severity, and delivery in a larger hospital predicted greater likelihood of post-GDM follow-up. Women with a prepregnancy primary care visit of any type were two to three times more likely to receive postpartum glucose testing and primary care at 1 year, and 3.5 times more likely to have obtained testing and primary care at 3 years after delivery.ConclusionsA history of use of primary care services before a pregnancy complicated by GDM seems to enhance the likelihood of postdelivery surveillance and preventive care, and thus reduce the risk of undetected early-onset type 2 diabetes. An emphasis on promoting early primary care connections for women in their early reproductive years, in addition to its overall value, is a promising strategy for ensuring follow-up testing and care for women after complicated pregnancies that forewarn risk for later chronic illness. Health systems should focus on models of care that connect primary and reproductive/maternity care before, during, and long after pregnancies occur.     

Racial/Ethnic Disparities in Gestational Diabetes Mellitus: Findings from a Population-Based Survey

PurposeWe sought to explore racial/ethnic disparities in the prevalence of gestational diabetes mellitus (GDM) in a population-based sample.MethodsData from the Oregon Pregnancy Risk Assessment Monitoring System (PRAMS), a stratified, random sample of postpartum women who delivered in Oregon in 2004 and 2005 (n = 3,883; weighted response rate, 75.2%) and linked birth certificates were analyzed. Hispanic, non-Hispanic Black, non-Hispanic American Indian, and non-Hispanic Asian/Pacific Islander (API) women were oversampled. We categorized women as having had GDM if they gave an affirmative answer on the birth certificate or the PRAMS survey.ResultsNon-Hispanic API women had the highest prevalence of GDM (14.8%); this was true for women with both a normal and a high body mass index (BMI). Asian women were more likely to have had GDM than Pacific Islander women. On multivariate analysis, non-Hispanic APIs were significantly more likely to have a pregnancy complicated by GDM (adjusted odds ratio, 2.26; 95% confidence interval, 1.23–4.13) than non-Hispanic White women.ConclusionNon-Hispanic API women, especially Asian women with both normal and high BMI, have increased risk of GDM. Future research should examine the unique risk factors experienced by Asians and health practitioners should be vigilant in screening for GDM regardless of BMI.     

Understanding Why Some Women with a History of Gestational Diabetes Do Not Get Tested for Diabetes

BackgroundThe proportion of women with previous gestational diabetes mellitus (GDM) receiving postpartum diabetes testing is far less than desired. Even in health care systems with high testing rates, some women remain untested. We explored what helps and what hinders women to obtain recommended testing.MethodsIn this mixed methods study, we recruited 139 patients with a history of GDM in their most recent pregnancy (6 months to 4.5 years before study enrollment) from a delivery system that had instituted a quality improvement program to increase postpartum diabetes testing rates. We determined whether they had received a postpartum diabetes test according to American Diabetes Association guidelines. Using survey data, we ran logistic regression models to assess correlates of testing status, and we conducted in-depth interviews with 22 women to provide greater context to their survey responses.ResultsOf the 139 women, 21 women (15%) did not complete recommended diabetes testing. From the survey data, women who visited a primary care provider had 72% (95% CI, 0.09–0.83) lesser odds of not having been tested. From the qualitative interviews, difficulty fitting testing around work and caregiver demands were the most common reasons for not testing. Untested women interpreted providers' reassurances that diabetes would resolve after delivery and lack of reminders to reschedule missed appointments and to complete diabetes testing as indicators that their physicians were not concerned about their diabetes risk.ConclusionsAmong hard-to-reach women, multiple demands on their time were common explanations for not receiving a postpartum diabetes test. Consistent messages regarding long-term diabetes risk during pregnancy, access to postpartum primary care and convenient lab appointments, and systematic reminders to providers and patients are approaches that, in combination, may influence more resistant women to test.     

Postpartum screening for diabetes among Medicaid-eligible South Carolina women with gestational diabetes

PurposeTo examine the rate of timely postpartum screening for diabetes among Medicaid-eligible women with gestational diabetes mellitus (GDM).MethodsWe examined a retrospective cohort of Medicaid women with a live birth between 2004 and 2007. Women with singleton live births at greater than 28 weeks gestation were included in the cohort and their screening receipt tracked. Only the first qualifying pregnancy within the observation period was assessed. Birth certificate records were linked with hospital discharge data, outpatient prenatal care claims to identify women with GDM (n = 6,239). Medicaid postpartum claims for these women were examined to determine receipt of postpartum screening for diabetes within 5 to 13 weeks. Women with any indication of a dedicated plasma glucose test identified by CPT codes 82947, 82950, 82951, and 82952 during this time period were considered to meet the definition of screening.ResultsApproximately 3.4% of women identified as having GDM were screened for diabetes postpartum. Adjusted analysis found women not attending the postpartum visit (odds ratio [OR], 0.58; 95% confidence interval [CI], 0.37–0.91) and women receiving inadequate prenatal care (OR, 0.57; 95% CI, 0.34–0.95) were less likely to receive postpartum screening for diabetes. Conversely, women 20 to 34 years of age (OR, 1.79; 95% CI, 1.21–2.66) and women who were obese (OR, 2.28; 95% CI, 1.56–3.32) were more likely to be screened.ConclusionsMedicaid is a primary source of insurance for many women; however, for most coverage ends at 60 days postpartum, leaving a narrow window of opportunity for postpartum screening. Extended periods of coverage may be beneficial in ensuring the opportunity to receive adequate postpartum care, including screening for diabetes.     

Factors Associated with Depressive Symptoms in the Early Postpartum Period Among Women with Recent Gestational Diabetes Mellitus

Women with gestational diabetes mellitus (GDM) have a substantial risk of subsequently developing type 2 diabetes. This risk may be mitigated by engaging in healthy eating, physical activity, and weight loss when indicated. Since postpartum depressive symptoms may impair a woman’s ability to engage in lifestyle changes, we sought to identify factors associated with depressive symptoms in the early postpartum period among women with recent GDM. The participants are part of the baseline cohort of the TEAM GDM (Taking Early Action for Mothers with Gestational Diabetes Mellitus) study, a one-year randomized trial of a lifestyle intervention program for women with a recent history of GDM, conducted in Boston, Massachusetts between June 2010 and September 2012. We administered the Edinburgh Postnatal Depression Scale (EPDS) at 4–15 weeks postpartum to women whose most recent pregnancy was complicated by GDM (confirmed by laboratory data or medical record review). An EPDS score ≥9 indicated depressive symptoms. We measured height and thyroid stimulating hormone, and administered a questionnaire to collect demographic data and information about breastfeeding and sleep. We calculated body mass index (BMI) using self-reported pre-pregnancy weight and measured height. We reviewed medical records to obtain data about medical history, including history of depression, mode of delivery, and insulin use during pregnancy. We conducted bivariable analyses to identify correlates of postpartum depressive symptoms, and then modeled the odds of postpartum depressive symptoms using multivariable logistic regression. Our study included 71 women (mean age 33 years ± 5; 59 % White, 28 % African-American, 13 % Asian, with 21 % identifying as Hispanic; mean pre-pregnancy BMI 30 kg/m² ± 6). Thirty-four percent of the women scored ≥9 on the EPDS at the postpartum visit. In the best fit model, factors associated with depressive symptoms at 6 weeks postpartum included cesarean delivery (aOR 4.32, 95 % CI 1.46, 13.99) and gestational weight gain (aOR 1.21 [1.02, 1.46], for each additional 5 lbs gained). Use of insulin during pregnancy, breastfeeding, personal history of depression, and lack of a partner were not retained in the model. Identifying factors associated with postpartum depression in women with GDM is important since depression may interfere with lifestyle change efforts in the postpartum period. In this study, cesarean delivery and greater gestational weight gain were correlated with postpartum depressive symptoms among women with recent GDM (Clinicaltrials.gov NCT01158131).     

Continuity of primary care and prenatal care adequacy among women with disabilities in Ontario: A population-based cohort study

BackgroundWomen with disabilities experience elevated risks for pregnancy complications and report barriers accessing prenatal care. Emerging evidence highlights the significant role primary care providers play in promoting preventive services like prenatal care.ObjectiveTo examine the relationship between continuity of primary care (COC) and prenatal care adequacy among women with disabilities.MethodsWe conducted a population-based study using health administrative data in Ontario, Canada. The study population included 15- to 49-year-old women with physical (n = 106,555), sensory (n = 32,194), intellectual/developmental (n = 1515), and multiple (n = 6543) disabilities who had a singleton livebirth or stillbirth in 2003–2017 and ≥ 3 primary care visits < 2 years before conception. COC was measured using the Usual Provider of Care Index. Nominal logistic regression was used to compute adjusted odds ratios (aOR) for prenatal care adequacy, measured using the Revised-Graduated Prenatal Care Utilization Index, for women with low versus moderate/high COC, controlling for other social and medical characteristics.ResultsWomen with disabilities with low COC, versus those with moderate/high COC, had increased odds of no (aOR 1.42, 95% CI 1.29–1.56), inadequate (aOR 1.19, 95% CI 1.16–1.23), and intensive prenatal care (aOR 1.22, 95% CI 1.19–1.25) versus adequate. In additional analyses, women with low COC and no/inadequate prenatal care were the most socially disadvantaged among the cohort, and those with low COC and intensive prenatal care had the greatest medical need.ConclusionImproving primary care access for women with disabilities, particularly those experiencing social disadvantage, could lead to better prenatal care access.     

Maternal Sociodemographic Characteristics,Experiences and Health Behaviors Associated with Postpartum Care Utilization: Evidence from Maryland PRAMS Dataset, 2012–2013

Objectives Postpartum visits are increasingly recognized as a window of opportunity for health care providers to counsel new mothers and promote healthy behaviors, including increasing contraceptive use and screening for postpartum depression. In Maryland, there is a lack of research on postpartum visit (PPV) attendance and the specific risk factors associated with not receiving postpartum care. In this study, we estimated the proportion of mothers in Maryland who attended a PPV and assessed maternal sociodemographic characteristics and health behaviors associated with PPV non-attendance. Methods Data were analyzed from the 2012 and 2013 Maryland Pregnancy Risk Assessment Monitoring System (n?=?2204). Bivariate and multivariable logistic regression were performed to examine the association between covariates and PPV non-attendance. Results Overall, 89.6% of women reported PPV attendance. Bivariate analyses between maternal sociodemographic and health behavior characteristics and PPV non-attendance indicated that being unmarried (OR 3.03, 95% CI 2.12–4.31), experiencing infant loss (OR 7.17, 95% CI 2.57–19.97), working during pregnancy (OR 0.44, 95% CI 0.31–0.63) and not receiving dental care (OR 2.03, 95% CI 1.43–2.88) as significant risk factors for PPV non-attendance. After controlling for known and theoretical confounders, experiencing an infant loss (aOR 5.18, 95% CI 1.54–17.4), not receiving dental care (aOR 1.54, 95% CI 1.06–2.26) and working during pregnancy (aOR 0.61, 95% CI 0.41–0.93) emerged as strong predictors of PPV non-attendance. Conclusions for Practice Mothers who recently experienced an infant death were at greatest risk for not attending a PPV, suggesting the need to establish comprehensive support networks, including grief counseling and additional service reminders for mothers who experienced an infant death.     

2009 IOM guidelines for gestational weight gain: how well do they predict outcomes across ethnic groups?

ABSTRACT

Objective: To determine whether the Institute Of Medicine's (IOM) 2009 guidelines for weight-gain during pregnancy are predictive of maternal and infant outcomes in ethnic minority populations.

Methods: We designed a population-based study using administrative data on 181,948 women who delivered live singleton births in Washington State between 2006–2008. We examined risks of gestational hypertension, preeclampsia/eclampsia, cesarean delivery, and extended hospital stay in White, Black, Native-American, East-Asian, Hispanic, South-Asian and Hawaiian/Pacific islander women according to whether they gained more or less weight during pregnancy than recommended by IOM guidelines. We also examined risks of neonatal outcomes including Apgar score <7 at 5 min, admission to NICU, requirement for ventilation, and a diagnosis of small or large for gestational age at birth.

Results: Gaining too much weight was associated with increased odds for gestational hypertension (adjusted OR (aOR) ranged between 1.53–2.22), preeclampsia/eclampsia (aOR 1.44–1.81), cesarean delivery (aOR 1.07–1.38) and extended hospital stay (aOR 1.06–1.28) in all ethnic groups. Gaining too little weight was associated with decreased odds for gestational hypertension and delivery by cesarean section in Whites, Blacks and Hispanics. Gaining less weight or more weight than recommended was associated with increased odds for small for gestational age and large for gestational age infants respectively, in all ethnic groups.

Conclusions: Adherence to the 2009 IOM guidelines for weight gain during pregnancy reduces risk for various adverse maternal outcomes in all ethnic groups studied. However, the guidelines were less predictive of infant outcomes with the exception of small and large for gestational age.

Healthcare Utilization in the Postpartum Period Among Illinois Women with Medicaid Paid Claims for Delivery, 2009–2010

Purpose Postpartum care can provide the critical link between pregnancy and well-woman healthcare, improving women’s health during the interconception period and beyond. However, little is known about current utilization patterns. This study describes the patterns of postpartum care experienced by Illinois women with Medicaid-paid deliveries. Methods Medicaid claims for women delivering infants in Illinois in 2009–2010 were analyzed for the receipt, timing and patterns of postpartum care, as identified through International Classification of Diseases Revision 9—Clinical Modification and Current Procedural Terminology© codes for routine postpartum care (43.4 % of visits), other postpartum services (e.g., depression screening, family planning), and other office visits for non-acute care. Results Over 90,000 visits to 55,577 women were identified, with 81.1 % of women experiencing any care during the first 90 days postpartum. Approximately 40 % had one visit, while 31 and 29 % had two and three or more visits, respectively. Thirty-four percent had their first visit <21 days postpartum, while 56 % had the first visit between 21 and 56 days postpartum. Compared with non-Hispanic whites, African-Americans had lower rates of receiving any care (73.6 vs. 86.5 %), fewer visits (48.0 vs. 33.5 % with only one visit), and later first visits (13.6 vs. 7.3 %, >56 days). Conclusions for Practice The vast majority of Illinois women with Medicaid-paid deliveries interact with the healthcare system during the first 3 months postpartum, though not always for a routine postpartum visit. Strategies to optimize postpartum health should encourage a higher level of coordination among services and linkage to well-woman care to improve subsequent women and infants’ health outcomes.     

Knowledge,attitudes, and practices regarding seasonal influenza vaccination during pregnancy in Costa Rica: A mixed-methods study

BackgroundInfluenza increases stillbirth risk, morbidity and mortality in pregnant women. Vaccination protects pregnant women against severe disease and indirectly protects their infants, but coverage among pregnant women remains low worldwide. We aimed to describe knowledge, attitudes, and practices (KAP) regarding seasonal influenza vaccination among postpartum women and prenatal care physicians in Costa Rica.MethodsWe conducted cross-sectional KAP surveys to women one to three days after childbirth at Costa Rican Social Security Fund maternity hospitals, and obstetricians and general practitioners who provided prenatal care in 2017. Principal components analysis, multiple imputation, and logistic regression were used to examine associations between influenza vaccination and demographics, prenatal care, and sources of information—separately for postpartum women and physicians. We also held two focus groups of six healthcare workers each to further describe vaccination KAP.ResultsWe surveyed 642 postpartum women and 146 physicians in maternity hospitals in five Costa Rican provinces of whom 85.5 % (95 % CI: 82.6 %-88.0 %) and 57.9 % (95 % CI: 49.6 %-65.7 %) were vaccinated for influenza, respectively. Factors associated with influenza vaccination for postpartum women included tetanus vaccination (aOR: 3.62, 95 % CI: 1.89–6.92); received vaccination recommendations from clinicians during prenatal check-ups (aOR: 3.39, 95 % CI: 2.06–5.59); had other children in household vaccinated for influenza (aOR: 2.25, 95 % CI: 1.08–4.68); and secondary/university education (aOR: 0.15–0.31) with no formal education as reference. For postpartum women, reasons for vaccination were perceived benefits for mother and infant, whereas not being offered vaccines was most cited for non-vaccination. Most prenatal care physicians recommended influenza vaccines during prenatal check-ups but believed vaccination causes flu-like symptoms.ConclusionVaccination campaigns and provisions of free vaccines effectively increased knowledge and coverage among women in Costa Rica. To improve access, women should be offered vaccines during prenatal care appointments. Educating healthcare workers about vaccine benefits for themselves and patients is needed to mitigate safety concerns.     

Early Resumption of Sexual Intercourse after First Childbirth and Unintended Pregnancy within Six Months

ObjectiveWe aimed to evaluate factors associated with early resumption of sexual intercourse after first childbirth and assess whether early intercourse is associated with unprotected intercourse, subsequent pregnancy, and unintended pregnancy over 6 months.MethodsThis secondary analysis used data from the First Baby Study, a prospective study of women aged 18–35 years with singleton pregnancies who delivered at 76 hospitals in Pennsylvania. At 1 and 6 months postpartum, women were asked about intercourse and the use of birth control since childbirth. We compared women who resumed intercourse in the first month after childbirth (early resumption) with those who resumed intercourse later, via multivariable logistic regression models.ResultsIn our cohort, 261 of 2,643 women (9.9%) reported first intercourse within the first postpartum month (7–31 days). Women who resumed intercourse early were less educated, younger, and less likely to breastfeed, have had a perineal laceration, or have had an episiotomy than those who resumed intercourse later. In addition, they were more likely to have unprotected intercourse in at least one of the first 6 months after first childbirth (adjusted odds ratio [aOR], 2.33; 95% confidence interval [CI], 1.76–3.09); to be pregnant by 6 months postpartum (aOR, 3.03; 95% CI, 1.48–6.20); and to report that pregnancy as unintended (aOR, 3.32; 95% CI, 1.50–7.36).ConclusionsNearly 10% of women resumed intercourse in the first month after childbirth. Because early resumption of intercourse was associated with a greater likelihood of unprotected intercourse and unintended pregnancy within 6 months of first childbirth, clinicians should focus efforts on comprehensive family planning and contraception counseling beginning in the prenatal period.     

Association Between Birth Weight and Risk of Pregnancy-Induced Hypertension and Gestational Diabetes in Japanese Women: JPHC-NEXT Study

BackgroundAlthough prevalence of low birth weight has increased in the last 3 decades in Japan, no studies in Japanese women have investigated whether birth weight is associated with the risk of pregnancy complications, such as pregnancy-induced hypertension (PIH) and gestational diabetes mellitus (GDM).MethodsWe used data from the Japan Public Health Center-based Prospective Study for the Next Generation (JPHC-NEXT), a population-based cohort study in Japan that launched in 2011. In the main analysis, we included 46,365 women who had been pregnant at least once, for whom information on birth weight and events during their pregnancy was obtained using a self-administered questionnaire. Women were divided into five categories according to their birth weight, and the relationship between birth weight and risk of PIH and GDM was examined using multilevel logistic regression analyses with place of residence as a random effect.ResultsCompared to women born with birth weight of 3,000–3,999 grams, the risk of PIH was significantly higher among women born <1,500 grams (adjusted odd ratio [aOR] 1.60; 95% confidence interval [CI], 1.17–2.21), 1,500–2,499 grams (aOR 1.16; 95% CI, 1.03–1.30), and 2,500–2,999 grams (aOR 1.13; 95% CI, 1.04–1.22). The risk of GDM was significantly higher among women born 1,500–2,499 grams (aOR 1.20; 95% CI, 1.02–1.42), albeit non-significant association among women in other birthweight categories.ConclusionsWe observed an increased risk of PIH among women born with lower birth weight albeit non-significant increased risk of GDM among Japanese women.Key words: gestational diabetes mellitus, lower birth weight, pregnancy induce hypertension, transgenerational effect     

Postpartum Contraception Use by Urban/Rural Status: An Analysis of the Michigan Pregnancy Risk Assessment Monitoring System Data

ObjectiveWe sought to examine rural/urban differences in postpartum contraceptive use, which are underexplored in the literature.MethodsWe analyzed phase 5 (2004–2008) of the Michigan Pregnancy Risk Assessment Monitoring System (PRAMS) survey. Using Rural–Urban Commuting Area codes and weighted multinomial logistic regression, we examined the association between self-reported postpartum contraceptive method and rural/urban residence among postpartum women not desiring pregnancy (n = 6,468).ResultsPostpartum (mean, 16.5 weeks after delivery), 14.4% of respondents were using sterilization, 6.7% long-acting reversible contraception (LARC), 37.3% moderately effective hormonal methods, 38.4% less effective methods or no method, and 3.2% abstinence. Multivariable analysis yielded sporadic geographic patterns. Odds of method use varied significantly by age, parity, body mass index, and breastfeeding status. Not discussing contraception with a prenatal healthcare provider decreased odds of postpartum LARC use (odds ratio, 0.52; 95% CI, 0.36–0.75). Number of prenatal visits and weeks since delivery were not associated with postpartum contraception method.ConclusionsWe did not observe strong variation in postpartum contraceptive use based on geography. Low uptake of highly effective contraception across rural and urban areas suggests a need for education and outreach regarding these methods.
