Effect of a Low-Glycemic Load Diet Intervention on Maternal and Pregnancy Outcomes in Obese Pregnant Women.

The increased prevalence of obese, pregnant women who have a higher risk of glucose intolerance warrants the need for nutritional interventions to improve maternal glucose homeostasis. In this study, the effect of a low-glycemic load (GL) (n = 28) was compared to a high-GL (n = 34) dietary intervention during the second half of pregnancy in obese women (body mass index (BMI) > 30 or a body fat >35%). Anthropometric and metabolic parameters were assessed at baseline (20 week) and at 28 and 34 weeks gestation. For the primary outcome 3h-glucose-iAUC (3h-incremental area under the curve), mean between-group differences were non-significant at every study timepoint (p = 0.6, 0.3, and 0.8 at 20, 28, and 34 weeks, respectively) and also assessing the mean change over the study period (p = 0.6). Furthermore, there was no statistically significant difference between the two intervention groups for any of the other examined outcomes (p ≥ 0.07). In the pooled cohort, there was no significant effect of dietary GL on any metabolic or anthropometric outcome (p ≥ 0.2). A post hoc analysis comparing the study women to a cohort of overweight or obese pregnant women who received only routine care showed that the non-study women were more likely to gain excess weight (p = 0.046) and to deliver large-for-gestational-age (LGA) (p = 0.01) or macrosomic (p = 0.006) infants. Thus, a low-GL diet consumed during the last half of pregnancy did not improve pregnancy outcomes in obese women, but in comparison to non-study women, dietary counseling reduced the risk of adverse outcomes.

Reproductive Rights and Women's Mental Health: Essential Information for the Obstetrician-Gynecologist.

Reproductive health care is crucial to women's well-being and that of their families. State and federal laws restricting access to contraception and abortion in the United States are proliferating. Often the given rationales for these laws state or imply that access to contraception and abortion promote promiscuity, and/or that abortion is medically dangerous and causes a variety of adverse obstetric, medical, and psychological sequelae. These rationales lack scientific foundation. This article provides the evidence for the safety of abortion, for both women and girls, and encourages readers to advocate against restrictions.

Cardiovascular Disease-Related Pregnancy Complications Are Associated with Increased Maternal Levels and Trajectories of Cardiovascular Disease Biomarkers During and After Pregnancy.

Background: Having a pregnancy complicated by hypertensive disorders of pregnancy (HDP) and/or having a small or preterm baby put a woman at risk for later cardiovascular disease (CVD). It is uncertain if higher maternal CVD risk factors (reflected by increased peripartum CVD biomarker levels) account for this risk, or if experiencing a complicated pregnancy itself increases a woman's CVD risk (reflected by an increase in biomarker trajectories from early pregnancy to postpartum). Methods: We conducted a secondary analysis of an 8-week mindful eating and stress reduction intervention in 110 pregnant women. We used mixed linear regression analysis to compare CVD biomarker levels and trajectories, between women with and without a CVD-related pregnancy complication (including HDP [gestational hypertension or preeclampsia] or having a small for gestational age [<10th percentile] or preterm [<37 weeks] baby), at three times: (1) 12-20 weeks of gestation, (2) 3 months postpartum, and (3) 9 months postpartum. CVD biomarkers studied included serum glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR), body mass index (BMI), blood pressure (BP), interleukin-6 (IL-6), tumor necrosis factor, and lipids. We adjusted for age, maternal smoking, prepregnancy BMI, BP, age × time, and BMI × time. Results: Women had a mean age of 28 years (standard deviation [SD] 6), mean prior pregnancies of 0.8 (SD 1.0), and 22 women had one or more CVD-related pregnancy complications. HOMA-IR, diastolic BP, triglyceride, high-density lipoprotein cholesterol, and IL-6 average levels, but not trajectories, differed among women with complicated versus normal pregnancy (all p values were ≤0.04). Peripartum glucose and systolic BP trajectories were statistically greater in complicated versus normal pregnancies (p values were 0.008 and 0.01, respectively). Conclusion: We conclude that the experience of a complicated pregnancy in addition to elevated CVD risk factor levels may both increase a woman's risk of future CVD.

Meeting Women Where They Are: Integration of Care As the Foundation of Treatment for At-Risk Pregnant and Postpartum Women.

Purpose In these times of rapidly changing health care policies, those involved in the health care of women, especially during the reproductive years, have a unique and daunting opportunity. There is great potential to positively impact women's health through focus on prevention, attention to addressing disparities, and new focus on the integration of behavioral health care in primary care settings. Description In this report from the field, we suggest that the integration of mental health care into other health services and addressing underlying social needs by partnering with community-based organizations should be a top priority for all settings seeking to provide excellent health care for women. Assessment We describe our experience in a diverse, urban, safety net system to draw attention to four areas of innovation that others might adapt in their own systems: (1) addressing social support and other social determinants of health; (2) tailoring services to the specific needs of a population; (3) developing integrated and intensive cross-disciplinary services for high-risk pregnant women; and (4) bridging the divide between prenatal and postpartum care. Conclusion Women are more likely to be engaged with healthcare during their pregnancy. This engagement, however limited, may be a unique "window of opportunity" to help them address mental health concerns and implement positive behavior change. Future work should include research and program evaluation of innovative programs designed to serve the entire family and meeting at-risk women where they are.

Applying the COM-B model to creation of an IT-enabled health coaching and resource linkage program for low-income Latina moms with recent gestational diabetes: the STAR MAMA program.

BACKGROUND: One of the fastest growing risk groups for early onset of diabetes is women with a recent pregnancy complicated by gestational diabetes, and for this group, Latinas are the largest at-risk group in the USA. Although evidence-based interventions, such as the Diabetes Prevention Program (DPP), which focuses on low-cost changes in eating, physical activity and weight management can lower diabetes risk and delay onset, these programs have yet to be tailored to postpartum Latina women. This study aims to tailor a IT-enabled health communication program to promote DPP-concordant behavior change among postpartum Latina women with recent gestational diabetes. The COM-B model (incorporating Capability, Opportunity, and Motivational behavioral barriers and enablers) and the Behavior Change Wheel (BCW) framework, convey a theoretically based approach for intervention development. We combined a health literacy-tailored health IT tool for reaching ethnic minority patients with diabetes with a BCW-based approach to develop a health coaching intervention targeted to postpartum Latina women with recent gestational diabetes. Current evidence, four focus groups (n = 22 participants), and input from a Regional Consortium of health care providers, diabetes experts, and health literacy practitioners informed the intervention development. Thematic analysis of focus group data used the COM-B model to determine content. Relevant cultural, theoretical, and technological components that underpin the design and development of the intervention were selected using the BCW framework. RESULTS: STAR MAMA delivers DPP content in Spanish and English using health communication strategies to: (1) validate the emotions and experiences postpartum women struggle with; (2) encourage integration of prevention strategies into family life through mothers becoming intergenerational custodians of health; and (3) increase social and material supports through referral to social networks, health coaches, and community resources. Feasibility, acceptability, and health-related outcomes (weight loss, physical activity, consumption of healthy foods, breastfeeding, and glucose screening) will be evaluated at 9 months postpartum using a randomized controlled trial design. CONCLUSIONS: STAR MAMA provides a DPP-based intervention that integrates theory-based design steps. Through systematic use of behavioral theory to inform intervention development, STAR MAMA may represent a strategy to develop health IT intervention tools to meet the needs of diverse populations.

Prepregnancy Body Mass Index and Infant Mortality in 38 U.S. States, 2012-2013.

OBJECTIVE: To estimate whether prepregnancy body mass index (BMI) is related to infant mortality and whether adherence to weight gain recommendations mitigates the relationship between BMI and infant mortality. METHODS: This was a cohort study using 2012-2013 U.S. national linked birth certificate and infant death files for 38 states and the District of Columbia with the BMI measure, including 6,419,836 singleton births and 36,691 infant deaths (infant mortality rate 5.72/1,000). Prenatal weight gain in three categories was based on adherence to Institute of Medicine recommendations. The outcome measure was infant deaths in the first year of life subdivided into two time periods: neonatal (less than 28 days) and postneonatal (28 days to 1 year). RESULTS: With normal prepregnancy weight as a reference, after adjustment, the odds ratio (OR) for an infant death rose from 1.32 (95% confidence interval [CI] 1.27-1.37) for mothers in the obese I category to 1.73 (95% CI 1.64-1.83) for obese III. Higher BMI was related to higher rates of both neonatal and postneonatal mortality. The adjusted OR for the risk of an infant death among singleton, term, vertex births for those gaining less than the recommended weight was 1.07 (95% CI 1.01-1.12) and 1.04 (95% CI 0.99-1.09) for those gaining more than recommended. CONCLUSION: Even after controlling for multiple risks, prepregnancy BMI was strongly related to infant mortality. Efforts to lower the infant mortality rate may benefit from a focus on reducing obesity among women of reproductive age.

Incorporating Nurse-Midwifery Students into Graduate Medical Education: Lessons Learned in Interprofessional Education.

There is a current emphasis on interprofessional education in health care with the aim to improve teamwork and ultimately the quality and safety of care. As part of a Health Resources and Services Administration Advanced Nursing Education project, an interprofessional faculty and student team planned and implemented the first didactic coursework for nurse-midwifery and medical students at the University of California, San Francisco and responded to formative feedback in order to create a more meaningful educational experience for future combined cohorts. This article describes the process of including advanced nurse-midwifery students into 2 classes previously offered solely to medical students: 1) an elective in which students are matched with a pregnant woman to observe care that she receives before, during, and after giving birth; and 2) a required course on basic clinical care across the human lifespan. The development of these interprofessional courses, obstacles to success, feedback from students, and responses to course evaluations are reviewed. Themes identified in student course evaluations included uncertainty about interprofessional roles, disparity in clinical knowledge among learners, scheduling difficulties, and desire for more interprofessional education opportunities and additional time for facilitated interprofessional discussion. As a result of this feedback, more class time was designated for interprofessional exchange; less experienced rather than advanced midwifery students were included in both classes; and more interdisciplinary panel presentations were provided, along with clearer communication about student and clinician roles. Early project activities indicated nurse-midwifery students can be effectively included in existing medical student courses with revised curriculum and highlighted challenges that should be considered in the planning phase of similar projects in the future. This article is part of a special series of articles that address midwifery innovations in clinical practice, education, interprofessional collaboration, health policy, and global health.

Labor and Delivery Experiences of Mothers with Suspected Large Babies.

OBJECTIVE: To characterize the prevalence of and factors associated with clinicians' prenatal suspicion of a large baby; and to determine whether communicating fetal size concerns to patients was associated with labor and delivery interventions and outcomes. METHODS: We examined data from women without a prior cesarean who responded to Listening to Mothers III, a nationally representative survey of women who had given birth between July 2011 and June 2012 (n = 1960). We estimated the effect of having a suspected large baby (SLB) on the odds of six labor and delivery outcomes. RESULTS: Nearly one-third (31.2%) of women were told by their maternity care providers that their babies might be getting "quite large"; however, only 9.9% delivered a baby weighing ≥4000 g (19.7% among mothers with SLBs, 5.5% without). Women with SLBs had increased adjusted odds of medically-induced labor (AOR 1.9; 95% CI 1.4-2.6), attempted self-induced labor (AOR 1.9; 95% CI 1.4-2.7), and use of epidural analgesics (AOR 2.0; 95% CI 1.4-2.9). No differences were noted for overall cesarean rates, although women with SLBs were more likely to ask for (AOR 4.6; 95% CI 2.8-7.6) and have planned (AOR 1.8; 95% CI 1.0-4.5) cesarean deliveries. These associations were not affected by adjustment for gestational age and birthweight. CONCLUSIONS FOR PRACTICE: Only one in five US women who were told that their babies might be getting quite large actually delivered infants weighing ≥4000 g. However, the suspicion of a large baby was associated with an increase in perinatal interventions, regardless of actual fetal size.

Maternal differences and birth outcome disparities: Diversity within a high risk prenatal clinic.

BACKGROUND: We examined the influence of race/ethnicity on appointment attendance, maternal psychiatric and medical diagnoses, and birth outcomes within a diverse, low income, high risk pregnant population to determine whether birth outcome disparities would be lessened in a sample with high biopsychosocial risk across all groups. METHODS: Data were retrospectively obtained on all women scheduled for appointments in the San Francisco Genera Hospital (SFGH) High-Risk Obstetrics (HROB) clinic during a three-month period. General linear model and logistic regression procedures were used to examine the associations of race/ethnicity with maternal characteristics, clinic attendance, and birth outcomes. RESULTS: Our sample included 202 maternal-infant pairs (Hispanic 57%, Black 16%, Asian 15%, White 12%). Racial/ethnic differences were seen in language (p < .001), gravidity (p < .001), parity (p = .005), appointment attendance (p < .001), diabetes (p = .005), psychiatric diagnosis (p = .02), illicit drug use (p < .001), smoking (p < .001). These maternal characteristics, including rate of attendance at specialized prenatal appointments, did not predict birth outcomes with the exception of an association between diabetes and earlier gestational age (p = .03). In contrast, Black maternal race/ethnicity was associated with earlier gestational age at birth (p = .004) and lower birth weight (p < .001) compared to Whites. CONCLUSIONS: Within a diverse maternal population of high biopsychosocial risk, racial/ethnic disparities in birth outcomes persist. These disparities have implications for infant health trajectory throughout the lifecourse and for intervention implementation in high risk groups.

Counseling patients on preventing prenatal environmental exposures--a mixed-methods study of obstetricians.

OBJECTIVE: Describe the attitudes, beliefs, and practices of U.S. obstetricians on the topic of prenatal environmental exposures. STUDY DESIGN: A national online survey of American Congress of Obstetricians and Gynecologists (ACOG) fellows and 3 focus groups of obstetricians. RESULTS: We received 2,514 eligible survey responses, for a response rate of 14%. The majority (78%) of obstetricians agreed that they can reduce patient exposures to environmental health hazards by counseling patients; but 50% reported that they rarely take an environmental health history; less than 20% reported routinely asking about environmental exposures commonly found in pregnant women in the U.S.; and only 1 in 15 reported any training on the topic. Barriers to counseling included: a lack of knowledge of and uncertainty about the evidence; concerns that patients lack the capacity to reduce harmful exposures; and fear of causing anxiety among patients. CONCLUSION: U.S. obstetricians in our study recognized the potential impact of the environment on reproductive health, and the role that physicians could play in prevention, but reported numerous barriers to counseling patients. Medical education and training, evidence-based guidelines, and tools for communicating risks to patients are needed to support the clinical role in preventing environmental exposures that threaten patient health.

Elevated mercury levels in pregnant woman linked to skin cream from Mexico.

Mercury exposure during pregnancy can have serious health effects for a developing fetus including impacting the child's neurologic and cognitive development. Through biomonitoring in a low-income Latina population in California, we identified a patient with high levels of mercury and traced the source to face creams purchased in a pharmacy in Mexico.

Trends and characteristics of home vaginal birth after cesarean delivery in the United States and selected States.

OBJECTIVE: To examine trends and characteristics of home vaginal birth after cesarean delivery (VBAC) in the United States and selected states from 1990-2008. METHODS: Birth certificate data were used to track trends in home and hospital VBACs from 1990-2008. Data on planned home VBAC were analyzed by sociodemographic and medical characteristics for the 25 states reporting this information in 2008 and compared with hospital VBAC data. RESULTS: In 2008, there were approximately 42,000 hospital VBACs and approximately 1,000 home VBACs in the United States, up from 664 in 2003 and 656 in 1990. The percentage of home births that were VBACs increased from less than 1% in 1996 to 4% in 2008, whereas the percentage of hospital births that were VBACs decreased from 3% in 1996 to 1% in 2008. Planned home VBACs had a lower risk profile than hospital VBACs with fewer births to teenagers, unmarried women, or smokers; fewer preterm or low-birth-weight deliveries; and higher maternal education levels. CONCLUSION: Recent increases in the proportion of U.S. women with a prior cesarean delivery mean that an increasing number of women are faced with the choice and associated risks of either VBAC or repeat cesarean delivery. Recent restrictions in hospital VBAC availability have coincided with increases in home VBACs; however, home VBAC remains rare, with approximately 1,000 occurrences in 2008. LEVEL OF EVIDENCE: II.

Toxic environmental chemicals: the role of reproductive health professionals in preventing harmful exposures.

Every pregnant woman in the United States is exposed to many and varied environmental chemicals. Rapidly accumulating scientific evidence documents that widespread exposure to environmental chemicals at levels that are encountered in daily life can impact reproductive and developmental health adversely. Preconception and prenatal exposure to environmental chemicals are of particular importance because they may have a profound and lasting impact on health across the life course. Thus, prevention of developmental exposures to environmental chemicals would benefit greatly from the active participation of reproductive health professionals in clinical and policy arenas.

Prenatal weight gain: who is counseled?

BACKGROUND: Because prenatal counseling is associated with adherence to weight gain guidelines, we sought to identify patient-level characteristics associated with the receipt of counseling on weight gain, nutrition, and exercise during prenatal care. METHODS: We performed a secondary data analysis on a cohort of women enrolled in a prenatal counseling intervention study. We controlled for study group assignment (intervention versus usual care) as well as patient characteristics in a multivariable analysis. We performed three separate multivariable analyses for predictors of provider-patient discussions about (1) weight gain, (2) nutrition, and (3) exercise. RESULTS: The cohort consisted of 311 predominantly low-income prenatal patients receiving care at several sites in the San Francisco Bay Area. Prepregnancy body mass index, nutrition knowledge, maternal age, parity, and type of insurance were not significantly associated with receipt of counseling about weight gain, nutrition, and exercise. In the multivariable analysis, white women were significantly less likely to be counseled about nutrition than non-white women (p=0.02). Former smokers were more likely to receive counseling about nutrition and exercise than never smokers (p<0.05). More advanced gestational age was associated with a higher rate of counseling on weight gain (p=0.01). CONCLUSIONS: Despite having the highest rates of excessive weight gain nationally, white women were the least likely to receive counseling about nutrition during pregnancy. Interventions that prompt clinicians and simplify counseling may improve counseling rates for all patients during prenatal care.

Improving diet and exercise in pregnancy with Video Doctor counseling: a randomized trial.

OBJECTIVE: To determine if an interactive, computerized Video Doctor counseling tool improves self-reported diet and exercise in pregnant women. METHODS: A randomized trial comparing a Video Doctor intervention to usual care in ethnically diverse, low-income, English-speaking pregnant women was conducted. Brief messages about diet, exercise, and weight gain were delivered by an actor-portrayed Video Doctor twice during pregnancy. RESULTS: In the Video Doctor group (n=158), there were statistically significant increases from baseline in exercise (+28 min), intake of fruits and vegetables, whole grains, fish, avocado and nuts, and significant decreases in intake of sugary foods, refined grains, high fat meats, fried foods, solid fats, and fast food. In contrast, there were no changes from baseline for any of these outcomes in the usual care group (n=163). Nutrition knowledge improved significantly over time in both groups but more so in the Video Doctor group. Clinician-patient discussions about these topics occurred significantly more frequently in the Video Doctor group. There was no difference in weight gain between groups. CONCLUSION: A brief Video Doctor intervention can improve exercise and dietary behaviors in pregnant women. PRACTICE IMPLICATIONS: The Video Doctor can be integrated into prenatal care to assist clinicians with effective diet and exercise counseling.

The association between body mass index and gestational diabetes mellitus varies by race/ethnicity.

We examined body mass index (BMI) as a screening tool for gestational diabetes (GDM) and its sensitivity among different racial/ethnic groups. In a retrospective cohort study of 24,324 pregnant women at University of California, San Francisco, BMI was explored as a screening tool for GDM and was stratified by race/ethnicity. Sensitivity and specificity were examined using chi-square test and receiver-operator characteristic curves. BMI of ≥25.0 kg/m (2) as a screening threshold identified GDM in >76% of African-Americans, 58% of Latinas, and 46% of Caucasians, but only 25% of Asians ( P < 0.001). Controlling for confounders and comparing to a BMI of ≤25, African-Americans had the greatest increased risk of GDM (adjusted odds ratio [AOR] 5.1, 95% confidence interval [CI]: 3.0 to 8.5), followed by Caucasians (AOR 3.6, 95% CI: 2.7 to 4.8), Latinas (AOR 2.7, 95% CI: 1.9 to 3.8), and Asians (AOR 2.3, 95% CI: 1.8 to 3.0). BMI's screening characteristics to predict GDM varied by race/ethnicity. BMI can be used to counsel regarding the risk of developing GDM, but alone it is not a good screening tool.

When should women with placenta previa be delivered? A decision analysis.

OBJECTIVE: To determine the optimal gestational age of delivery for women with placenta previa by accounting for both neonatal and maternal outcomes. STUDY DESIGN: A decision-analytic model was designed comparing total maternal and neonatal quality-adjusted life years for delivery of women with previa at gestational ages from 34 to 38 weeks. At each week, we allowed for four different delivery strategies: (1) immediate delivery, without amniocentesis or steroids; (2) delivery 48 hours after steroid administration (without amniocentesis); (3) amniocentesis with delivery if fetal lung maturity (FLM) positive or retesting in one week if FLM negative; (4) amniocentesis with delivery if FLM testing is positive or administration of steroids if FLM negative. RESULTS: Delivery at 36 weeks, 48 hours after steroids, for women with previa optimizes maternal and neonatal outcomes. In sensitivity analyses, these results were robust to a wide range of variation in input assumptions. If it is assumed that steroids offer no neonatal benefit at this gestational age, outright delivery at 36 weeks' gestation is the best strategy. CONCLUSION: Steroid administration at 35 weeks and 5 days followed by delivery at 36 weeks for women with placenta previa optimizes maternal and neonatal outcomes.

Characteristics of planned and unplanned home births in 19 States.

OBJECTIVE: To estimate the differences in the characteristics of mothers having planned and unplanned home births that occurred at home in a 19-state reporting area in the United States in 2006. METHODS: Data are from the 2006 U.S. vital statistics natality file. Information on whether a home birth was planned or unplanned was available from 19 states, representing 49% of all home births nationally. Data were examined by maternal age, race or ethnicity, education, marital status, live birth order, birthplace of mother, gestational age, prenatal care, smoking status, state, population of county of residence, and birth attendant. We could not identify planned home births that resulted in a transfer to the hospital. RESULTS: Of the 11,787 home births with planning status recorded in the 19 states studied here, 9,810 (83.2%) were identified as planned home births. The proportion of all births that occurred at home that were planned varied from 54% to 98% across states. Unplanned home births are more likely to involve mothers who are non-white, younger, unmarried, foreign-born, smokers, not college-educated, and with no prenatal care. Unplanned home births are also more likely to be preterm and to be attended by someone who is neither a doctor nor a midwife and is listed as either "other" or "unknown." CONCLUSION: Planned and unplanned home births differ substantially in characteristics, and distinctions need to be drawn between the two in subsequent analyses. LEVEL OF EVIDENCE: III.

Maternal and paternal race/ethnicity are both associated with gestational diabetes.

OBJECTIVE: The objective of the study was to examine the rates of gestational diabetes mellitus (GDM) associated with both maternal and paternal race/ethnicity. STUDY DESIGN: This was a retrospective cohort study of all women delivered within a managed care network. Rates of GDM were calculated for maternal, paternal, and combined race/ethnicity. RESULTS: Among the 139,848 women with identified race/ethnicity, Asians had the highest rate (P < .001) of GDM (6.8%) as compared with whites (3.4%), African Americans (3.2%), and Hispanics (4.9%). When examining race/ethnicity controlling for potential confounders, we found that the rates of GDM were higher among Asian (adjusted odds ratio [aOR], 1.5; 95% confidence interval [CI], 1.4-1.6) and Hispanic (aOR, 1.2; 95% CI, 1.1-1.4) women as well as Asian (aOR, 1.4; 95% CI, 1.3-1.5) and Hispanic (aOR, 1.3; 95% CI, 1.2-1.4) men as compared with their white counterparts. CONCLUSION: We found that rates of GDM are affected by both maternal and paternal race/ethnicity. In both Asians and Hispanics, maternal and paternal race are equally associated with an increase in GDM. These differences may inform further investigation of the pathophysiology of GDM.
