Changes in Breastfeeding and Related Maternity Care Practices After Hurricanes Irma and Maria in Puerto Rico.

Background: Breastfeeding is recommended globally for most infants, especially during and after natural disasters when risk of adverse outcomes increases because of unsanitary conditions and lack of potable water. Materials and Methods: Using 2017-2019 data from Puerto Rico's Pregnancy Risk Assessment Monitoring System for 2,448 respondents with a recent live birth, we classified respondents into 4 hurricane exposure time periods based on infant birth month and year relative to when Hurricanes Irma and Maria occurred: (1) prehurricane; (2) acute hurricane; (3) posthurricane, early recovery; and (4) posthurricane, long-term recovery. We examined the association between maternity care practices during delivery hospitalization and exclusive breastfeeding at 3 months overall and stratified by time period. We also examined the associations between each maternity care practice and exclusive breastfeeding separately by time period. Results: Exclusive breastfeeding at 3 months was higher during the acute hurricane time period (adjusted prevalence ratio [aPR]: 1.43, 95% confidence interval: 1.09-1.87) than the prehurricane time period. Supportive maternity care practices were positively associated with exclusively breastfeeding, and practices that are risk factors for discontinuing breastfeeding were negatively associated with exclusive breastfeeding. Breastfeeding in the first hour (aPR range: 1.51-1.92) and rooming-in (aPR range: 1.50-2.58) were positively associated with exclusive breastfeeding across all time periods, except the prehurricane time period. Receipt of a gift pack with formula was negatively associated with exclusive breastfeeding (aPR range: 0.22-0.54) across all time periods. Conclusions: Maternity care practices during delivery hospitalization may influence breastfeeding behaviors and can improve breastfeeding during and after natural disasters. Strategies to maintain and improve these practices can be further supported during and after natural disasters.

Rape and Sexual Coercion Related Pregnancy in the United States.

INTRODUCTION: Sexual violence is a major public health problem in the U.S. that is associated with numerous health impacts, including pregnancy. U.S. population-based estimates (2010-2012) found that three million women experienced a rape-related pregnancy during their lifetimes. The current study presents more recent estimates of rape and sexual coercion-related pregnancy and examines prevalence by demographic characteristics. METHODS: Data years 2016/2017 were pooled from the National Intimate Partner and Sexual Violence Survey, a random-digit-dial telephone survey of U.S. non-institutionalized adults 18 years and older. The analysis, conducted in 2023, examined lifetime experience of rape-related pregnancy, sexual coercion-related pregnancy, or both among U.S. women. Authors calculated prevalence estimates with 95% CIs and conducted pairwise chi-square tests (p-value<0.05) to describe experiences by current age, race/ethnicity, and region of residence among U.S. women overall and among victims. RESULTS: One in 20 women in the U.S., or over 5.9 million women, experienced a pregnancy from either rape, sexual coercion, or both during their lifetimes. Non-Hispanic Multiracial women experienced a higher prevalence of all three outcomes compared with non-Hispanic White, non-Hispanic Black, and Hispanic women. Among victims who experienced pregnancy from rape, 28% experienced a sexually transmitted disease, 66% were injured, and over 80% were fearful or concerned for their safety. CONCLUSIONS: Pregnancy as a consequence of rape or sexual coercion is experienced by an estimated six million U.S. women. Prevention efforts may include healthcare screenings to identify violence exposure and use of evidence-based prevention approaches to reduce sexual violence.

Timing of Postpartum Depressive Symptoms.

Introduction: Postpartum depression is a serious public health problem that can adversely impact mother-child interactions. Few studies have examined depressive symptoms in the later (9-10 months) postpartum period. Methods: We analyzed data from the 2019 Pregnancy Risk Assessment Monitoring System (PRAMS) linked with data from a telephone follow-up survey administered to PRAMS respondents 9 to 10 months postpartum in 7 states (N = 1,954). We estimated the prevalence of postpartum depressive symptoms (PDS) at 9 to 10 months overall and by sociodemographic characteristics, prior depression (before or during pregnancy), PDS at 2 to 6 months, and other mental health characteristics. We used unadjusted prevalence ratios (PRs) to examine associations between those characteristics and PDS at 9 to 10 months. We also examined prevalence and associations with PDS at both time periods. Results: Prevalence of PDS at 9 to 10 months was 7.2%. Of those with PDS at 9 to 10 months, 57.4% had not reported depressive symptoms at 2 to 6 months. Prevalence of PDS at 9 to 10 months was associated with having Medicaid insurance postpartum (PR = 2.34; P = .001), prior depression (PR = 4.03; P <.001), and current postpartum anxiety (PR = 3.58; P <.001). Prevalence of PDS at both time periods was 3.1%. Of those with PDS at both time periods, 68.5% had prior depression. Conclusion: Nearly 3 in 5 women with PDS at 9 to 10 months did not report PDS at 2 to 6 months. Screening for depression throughout the first postpartum year can identify women who are not symptomatic early in the postpartum period but later develop symptoms.

The Postpartum Period: An Opportunity for Alcohol Screening and Counseling to Reduce Adverse Health Impacts.

OBJECTIVES: The postpartum period presents an opportunity to engage in discussions about alcohol consumption and related health harms. This study examined the prevalence of alcohol consumption among a sample of postpartum persons with a recent live birth and screening and brief intervention (alcohol SBI) or counseling by their providers. METHODS: We analyzed 2019 data from a telephone survey conducted 9 to 10 months postpartum among individuals who responded to the standard Pregnancy Risk Assessment Monitoring System survey in 6 states. Weighted prevalence estimates were calculated for alcohol consumption and alcohol SBI after birth through up to 10 months postpartum. RESULTS: Among 1790 respondents, 53.1% reported consuming alcohol postpartum. Among those who drank postpartum, 70.8% reported being asked about alcohol use by a healthcare provider. Slightly more than half of respondents who drank postpartum and were trying to get pregnant (52.4%) or were not using birth control at the time of the survey (59.8%) reported being asked about alcohol use. Approximately 25% of respondents who drank alcohol postpartum were advised about risky alcohol levels by a healthcare provider. Small proportions of individuals who drank alcohol postpartum and were pregnant or trying to get pregnant at the time of the survey were advised to reduce or stop drinking alcohol (10.6% and 2.3%, respectively). CONCLUSIONS: These findings suggest missed opportunities to promote health and prevent adverse alcohol-related health outcomes during the postpartum period through evidence-based tools such as alcohol SBI.

Pandemic-related stressors and mental health among women with a live birth in 2020.

The objective of this analysis was to assess the associations between pandemic-related stressors and feeling more anxious/depressed, among women with a live birth. We analyzed data from the Pregnancy Risk Assessment Monitoring System (PRAMS) COVID-19 maternal experiences supplement, implemented in 29 U.S. jurisdictions from October 2020-June 2021, among women with a live birth during April-December 2020. We examined stressors by type (economic, housing, childcare, food insecurity, partner, COVID-19 illness) and score (number of stressor types experienced [none, 1-2, 3-4, or 5-6]). Outcomes were feeling 1) more anxious and 2) more depressed than usual due to the pandemic. We calculated adjusted prevalence ratios estimating associations between stressors and outcomes. Among 12,525 respondents, half reported feeling more anxious and 28% more depressed than usual. The prevalence of stressor types was 50% economic, 41% childcare, 18% partner, 17% food insecurity, 12% housing, and 10% COVID-19 illness. Respondents who experienced partner stressors (anxious aPR: 1.81, 95% CI: 1.73-1.90; depressed aPR: 3.01, 95% CI: 2.78-3.25) and food insecurity (anxious aPR: 1.79, 95% CI: 1.71-1.88; depressed aPR: 2.32, 95% CI: 2.13-2.53) had the largest associations with feeling more anxious and depressed than usual. As stressor scores increased, so did the aPRs for feeling more anxious and more depressed due to the pandemic. COVID-19 stressors, not COVID-19 illness, were found to be significantly associated with feeling more anxious and depressed. Pregnant and postpartum women might benefit from access to supports and services to address pandemic-related stressors/social-determinants and feelings of anxiety and depression.

Polysubstance use during pregnancy: The importance of screening, patient education, and integrating a harm reduction perspective.

BACKGROUND: Substance use during pregnancy is associated with poor health outcomes. This study assessed substance use, polysubstance use, and use of select prescription medications during pregnancy. METHODS: We analyzed 2019 data from the Pregnancy Risk Assessment Monitoring System in 25 United States jurisdictions that included questions on prescription medications, tobacco, and illicit substance use during pregnancy. Alcohol and electronic cigarette use were assessed during the last three months of pregnancy, and all other substances and medications were assessed throughout pregnancy. Weighted prevalence estimates and 95% confidence intervals (CIs) were calculated. RESULTS: Nearly one-fifth of respondents who reported use of any substance reported use of at least one other substance during pregnancy. Cigarettes (8.1%; 95% CI 7.6-8.7%) and alcohol (7.4%; 95% CI 6.7-8.1%) were the most frequently reported substances, followed by cannabis (4.3%; 95% CI 3.9-4.7%). Substance use was higher among individuals who reported having depression or using antidepressants during pregnancy compared with those who did not report depression or antidepressant use. Illicit drug use prevalence was low (0.5%, 95% CI 0.4-0.7%); however, respondents reporting heroin use also frequently reported use of illicit stimulants (amphetamines: 51.7%, 95% CI 32.1-71.3% or cocaine: 26.5%, 95% CI 11.9-41.1%). Although prenatal clinician screening for alcohol and cigarette use was approximately 95%, fewer respondents (82.1%) reported being screened for cannabis or illicit substance use during pregnancy. CONCLUSIONS: One in five individuals who reported use of any substance during pregnancy engaged in polysubstance use, highlighting the importance of comprehensive screening and evidence-based interventions including harm reduction.

Association of Mental Health Conditions, Recent Stressful Life Events, and Adverse Childhood Experiences with Postpartum Substance Use - Seven States, 2019-2020.

Most pregnancy-related deaths due to mental health conditions, which include overdose and poisoning related to substance use disorder, occur during the late (43-365-day) postpartum period (1). Adverse childhood experiences and stressful life events are associated with increased substance use during pregnancy (2,3). Pregnancy Risk Assessment Monitoring System (PRAMS) respondents in seven states with high opioid overdose mortality rates were recontacted 9-10 months after giving birth in 2019 and asked about postpartum prescription opioid misuse,* tobacco use, unhealthy alcohol use,† and use of other substances.§ Substance and polysubstance use prevalence estimates were calculated, stratified by mental health and social adversity indicators. Overall, 25.6% of respondents reported postpartum substance use, and 5.9% reported polysubstance use. The following conditions were associated with higher substance and polysubstance use prevalence in postpartum women: depressive symptoms, depression, anxiety, adverse childhood experiences, and stressful life events. Substance use prevalence was higher among women who experienced six or more stressful life events during the year preceding the birth (67.1%) or four adverse childhood experiences related to household dysfunction (57.9%). One in five respondents who experienced six or more stressful life events in the year before giving birth and 26.3% of women with four adverse childhood experiences reported postpartum polysubstance use. Clinical and community- and systems-level interventions to improve postpartum health can include screening and treatment for depression, anxiety, and substance use disorders during the postpartum period. Evidence-based strategies can prevent adverse childhood experiences and mitigate the immediate and long-term harms.¶.

Associations of Adverse Childhood Experiences With Pregnancy and Infant Health.

INTRODUCTION: Adverse childhood experiences are associated with a host of negative outcomes; however, few have studied cumulative adverse childhood experiences in the context of pregnancy and infant health. This study examines state-level prevalence of adverse childhood experiences and associations with pregnancy- and infant health‒related indicators. METHODS: The study used 2016-2018 Pregnancy Risk Assessment Monitoring System population-based data from 5 states. Analyses were conducted for individual states and grouped states using similar adverse childhood experience items. Thirteen adverse childhood experience measures were included across 3 domains: abuse, neglect, and household challenges. Adverse childhood experience scores were calculated for the number of adverse childhood experiences experienced (0, 1, 2, ≥3) on the basis of available state measures. Fourteen pregnancy- and infant health‒related indicators were examined, including unwanted pregnancy, adequate prenatal care, experiences during pregnancy (e.g., smoking, abuse, depression), gestational diabetes, hypertensive disorders of pregnancy, birth outcomes (e.g., preterm birth), and breastfeeding. Adjusting for demographics, parity, health insurance status, and educational attainment, prevalence ratios and 95% CIs were calculated to examine the associations between pregnancy- and infant health‒related indicators and adverse childhood experience scores. RESULTS: Over 50% of respondents reported at least 1 adverse childhood experience and 13%-31% reported ≥3 adverse childhood experiences, depending on the state. Significant associations were identified in all adjusted models between adverse childhood experiences and unwanted pregnancy, smoking, physical abuse, and depression during pregnancy. CONCLUSIONS: Adverse childhood experiences are associated with risk factors that impact pregnancy and infant health. Preventing and mitigating adverse childhood experiences is an important strategy to improve pregnancy- and infant health‒related indicators.

Pregnant Women's Experiences During and After Hurricanes Irma and Maria, Pregnancy Risk Assessment Monitoring System, Puerto Rico, 2018.

OBJECTIVE: Exposure to natural disasters during and after pregnancy may increase adverse mental health outcomes. Hurricanes Irma and Maria struck Puerto Rico in September 2017. Our objectives were to understand hurricane-related experiences, maternal health concerns, and the impact of hurricane experiences on postpartum depressive symptoms (PDS). METHODS: We used data from the 2018 Pregnancy Risk Assessment Monitoring System to describe differences in maternal hurricane experiences among women who were pregnant during and after the 2017 hurricanes. We assessed maternal concerns and PDS. We estimated adjusted prevalence ratios (aPRs) and 95% CIs for the associations between hurricane experiences and PDS. RESULTS: The most frequently reported hurricane experiences were losing power for ≥1 week (97%) and feeling unsafe due to lack of order/security (70%). Almost 30% of women who were pregnant during the hurricanes reported missing prenatal care. PDS were reported by 13% of women. Most hurricane experiences were associated with an increased prevalence of PDS. Feeling unsafe (aPR = 2.4; 95% CI, 1.2-4.9) and having difficulty getting food (aPR = 2.1; 95% CI, 1.1-4.1) had the strongest associations. CONCLUSIONS: Most women who were pregnant during or after hurricanes Irma and Maria struck Puerto Rico reported negative hurricane experiences, and most experiences were associated with an increased prevalence of PDS. Understanding the experiences of pregnant women during and after disasters and identifying risks for adverse mental health outcomes after pregnancy are important to inform emergency preparedness and prenatal and postpartum care.

Recent Incarceration Exposure Among Parents of Live-Born Infants and Maternal and Child Health.

OBJECTIVE: Women who have direct exposure to incarceration or indirect exposure through their partner are at high risk for poor health behaviors and outcomes, which may have lasting impacts on their children. The objectives of this study were to estimate the prevalence of recent incarceration exposure among women with a recent live birth and assess the relationship between incarceration exposure and maternal and child health. METHODS: We used data from the Pregnancy Risk Assessment Monitoring System (36 states and New York City, 2012-2015; N = 146 329) to estimate the prevalence of women reporting that they or their husband/partner spent time in jail during the 12 months before giving birth. We used multivariable logistic regression to assess associations between incarceration exposure and maternal and infant health conditions. RESULTS: The prevalence of incarceration exposure shortly before or during pregnancy was 3.7% (95% CI, 3.6%-3.9%). Women with incarceration exposure had increased odds of prepregnancy hypertension (adjusted odds ratio [aOR] = 1.51; 95% CI, 1.26-1.81), prepregnancy and postpartum depressive symptoms (aOR = 1.95 [95% CI, 1.73-2.19] and 1.49 [95% CI, 1.32-1.67], respectively), and having an infant admitted to the neonatal intensive care unit (aOR = 1.18; 95% CI, 1.04-1.33). CONCLUSION: Because a parent's incarceration exposure is an adverse childhood experience with the potential to disrupt important developmental periods and have negative impacts on the socioemotional and health outcomes of children, it is critical for researchers and health care providers to better understand its impact on maternal and infant health. Prenatal and postnatal care may provide opportunities to address incarceration-related health risks.

Rapid Population-Based Surveillance of Prenatal and Postpartum Experiences During Public Health Emergencies, Puerto Rico, 2016‒2018.

The Pregnancy Risk Assessment Monitoring System-Zika Postpartum Emergency Response study, implemented in Puerto Rico during the Zika virus outbreak (2016-2017) and after Hurricanes Irma and María (2017-2018), collected pregnancy-related data using postpartum hospital-based surveys and telephone follow-up surveys. Response rates of 75% or more were observed across five study surveys. The study informed programs, increased the Puerto Rico Department of Health's capacity to conduct maternal‒infant health surveillance, and demonstrated the effectiveness of this methodology for collecting data during public health emergencies. (Am J Public Health. 2022;112(4):574-578. https://doi.org/10.2105/AJPH.2021.306687).

Prevalence of Experiencing Physical, Emotional, and Sexual Violence by a Current Intimate Partner during Pregnancy: Population-based Estimates from the Pregnancy Risk Assessment Monitoring System.

Intimate partner violence (IPV) during pregnancy presents a risk for maternal mental health problems, preterm birth, and having a low birthweight infant. We assessed the prevalence of self-reported physical, emotional, and sexual violence during pregnancy by a current partner among women with a recent live birth. We analyzed data from the 2016-2018 Pregnancy Risk Assessment Monitoring System in six states to calculate weighted prevalence estimates and 95% confidence intervals for experiences of violence by demographic characteristics, health care utilization, and selected risk factors. Overall, 5.7% of women reported any type of violence during pregnancy. Emotional violence was most prevalent (5.4%), followed by physical violence (1.5%), and sexual violence (0.9%). Among women who reported any violence, 67.6% reported one type of violence, 26.5% reported two types, and 6.0% reported three types. Reporting any violence was highest among women using marijuana or illicit substances, experiencing pre-pregnancy physical violence, reporting depression, reporting an unwanted pregnancy, and experiencing relationship problems such as getting divorced, separated, or arguing frequently with their partner. There was no difference in report of discussions with prenatal care providers by experience of violence. The majority of women did not report experiencing violence, however among those who did emotional violence was most frequently reported. Assessment for IPV is important, and health care providers can play an important role in screening. Coordinated prevention efforts to reduce the occurrence of IPV and community-wide resources are needed to ensure that pregnant women receive needed services and protection.

Response to "The Time has Come for All States to Measure Racial Discrimination: A Call to Action for the Pregnancy Risk Assessment Monitoring System (PRAMS)".

We respond to a recent call to action for the Pregnancy Risk Assessment Monitoring System (PRAMS) to include a "core" question or validated measure on discrimination to allow for systematic assessment of the impact of racial discrimination on adverse birth outcomes among a large population-based sample in the United States. We outline activities of the CDC PRAMS project that relate to this call to action.

Design and Methodology of the Study of Associated Risks of Stillbirth (SOARS) in Utah.

OBJECTIVES: The Utah Study of Associated Risks of Stillbirth (SOARS) collects data about stillbirths that are not included in medical records or on fetal death certificates. We describe the design, methods, and survey response rate from the first year of SOARS. METHODS: The Utah Department of Health identified all Utah women who experienced a stillbirth from June 1, 2018, through May 31, 2019, via fetal death certificates and invited them to participate in SOARS. The research team based the study protocol on the Pregnancy Risk Assessment Monitoring System surveillance of women with live births and modified it to be sensitive to women's recent experience of a stillbirth. We used fetal death certificates to examine survey response rates overall and by maternal characteristics, gestational age of the fetus, and month in which the loss occurred. RESULTS: Of 288 women invited to participate in the study, 167 (58.0%) completed the survey; 149 (89.2%) responded by mail and 18 (10.8%) by telephone. A higher proportion of women who were non-Hispanic White (vs other races/ethnicities), were married (vs unmarried), and had ≥high school education (vs

Workplace Leave and Breastfeeding Duration Among Postpartum Women, 2016-2018.

Objectives. To examine associations of workplace leave length with breastfeeding initiation and continuation at 1, 2, and 3 months. Methods. We analyzed 2016 to 2018 data for 10 sites in the United States from the Pregnancy Risk Assessment Monitoring System, a site-specific, population-based surveillance system that samples women with a recent live birth 2 to 6 months after birth. Using multivariable logistic regression, we examined associations of leave length (< 3 vs ≥ 3 months) with breastfeeding outcomes. Results. Among 12 301 postpartum women who planned to or had returned to the job they had during pregnancy, 42.1% reported taking unpaid leave, 37.5% reported paid leave, 18.2% reported both unpaid and paid leave, and 2.2% reported no leave. Approximately two thirds (66.2%) of women reported taking less than 3 months of leave. Although 91.2% of women initiated breastfeeding, 81.2%, 72.1%, and 65.3% of women continued breastfeeding at 1, 2, and 3 months, respectively. Shorter leave length (< 3 months), whether paid or unpaid, was associated with lower prevalence of breastfeeding at 2 and 3 months compared with 3 or more months of leave. Conclusions. Women with less than 3 months of leave reported shorter breastfeeding duration than did women with 3 or more months of leave. (Am J Public Health. 2021;111(11):2036-2045. https://doi.org/10.2105/AJPH.2021.306484).

The Impact of Dental Insurance and Medical Insurance on Dental Care Utilization During Pregnancy.

OBJECTIVE: To measure the association between dental and medical insurance with the receipt of dental cleaning during pregnancy. METHODS: We analyzed Pregnancy Risk Assessment Monitoring System (PRAMS) data from 2012 to 2015 on 145,051 women with a recent live birth from 36 states. We used adjusted prevalence ratios [aPR] from multivariable regression to examine the association of dental and medical insurance with receipt of dental cleaning during pregnancy, controlling for selected covariates that influence dental care utilization. RESULTS: Seventy-seven percent (77%) of all women reported having dental insurance during pregnancy. Receipt of dental cleaning before pregnancy was strongly associated with dental cleaning during pregnancy. Among women without pre-pregnancy dental cleaning who had dental insurance, those with Medicaid medical insurance had a significantly higher prevalence of dental cleaning during pregnancy [aPR = 1.42, 95% CI (1.32 - 1.52)], compared to those private medical insurance. Among women without pre-pregnancy dental cleaning, those without dental insurance but with Medicaid medical insurance were about 70% less likely to have dental cleaning during pregnancy compared to those with dental and private medical insurance. CONCLUSIONS FOR PRACTICE: With or without dental insurance, pre-pregnancy dental cleaning was strongly associated with dental cleaning during pregnancy. Dental insurance was an important determinant of dental utilization. Medical insurance had an independent and positive effect. This effect varied by private versus Medicaid medical insurance. Programs which provide women with dental insurance both before and during pregnancy could improve the oral health of maternal and infant populations.

Opportunities to Address Men's Health During the Perinatal Period - Puerto Rico, 2017.

Decreased use of health care services (1), increased exposure to occupational hazards, and higher rates of substance use (2) might contribute to men's poorer health outcomes when compared with such outcomes for women (3). During the transition to fatherhood, paternal health and involvement during pregnancy might have an impact on maternal and infant outcomes (4-6). To assess men's health-related behaviors and participation in fatherhood-related activities surrounding pregnancy, the Puerto Rico Department of Health and CDC analyzed data from the paternal survey of the Pregnancy Risk Assessment Monitoring System-Zika Postpartum Emergency Response (PRAMS-ZPER)* study. Fewer than one half (48.3%) of men attended a health care visit for themselves in the 12 months before their newborn's birth. However, most fathers attended one or more prenatal care visits (87.2%), were present at the birth (83.1%), and helped prepare for the newborn's arrival (e.g., by preparing the home [92.4%] or purchasing supplies [93.9%]). These findings suggest that opportunities are available for public health messaging directed toward fathers during the perinatal period to increase attention to their own health and health behaviors, and to emphasize the role they can play in supporting their families' overall health and well-being.

Prevalence of Home Births and Associated Risk Profile and Maternal Characteristics, 2016-2018.

OBJECTIVE: To estimate the prevalence of pregnancies that meet the low-risk criteria for planned home births and describe geographic and maternal characteristics of home births compared with hospital births. METHODS: Data from the 2016-2018 Pregnancy Risk Assessment Monitoring System (PRAMS), a survey among women with recent live births, and linked birth certificate variables were used to calculate the prevalence of home births that were considered low-risk. We defined low-risk pregnancy as a term (between 37 and 42 weeks of gestation), singleton gestation with a birth weight within the 10th-90th percentile mean for gestational age (as a proxy for estimated fetal size appropriate for gestational age), without prepregnancy or gestational diabetes or hypertension, and no vaginal birth after cesarean (VBAC). We also calculated the prevalence of home and hospital births by site and maternal characteristics. Weighted prevalence estimates are presented with 95% CIs to identify differences. RESULTS: The prevalence of home births was 1.1% (unweighted n=1,034), ranging from 0.1% (Alabama) to 2.6% (Montana); 64.9% of the pregnancies were low-risk. Among the 35.1% high-risk home births, 39.5% of neonates were large for gestational age, 20.5% of neonates were small for gestational age, 17.1% of the women had diabetes, 16.9% of the women had hypertension, 10.6% of the deliveries were VBACs, and 10.1% of the deliveries were preterm. A significantly higher percentage of women with home births than hospital births were non-Hispanic White (83.9% vs 56.5%), aged 35 years or older (24.0% vs 18.1%), with less than a high school-level of education (24.6% vs 12.2%), and reported no health insurance (27.0% vs 1.9%). A significantly lower percentage of women with home births than hospital births initiated prenatal visits in the first trimester (66.9% vs 87.1%), attended a postpartum visit (80.1% vs 90.0%), and most often laid their infants on their backs for sleep (59.3% vs 79.5%). CONCLUSIONS: Understanding the risk profile, geographic distribution, and characteristics of women with home births can guide efforts around safe birthing practices.

Preventing Vector-Borne Transmission of Zika Virus Infection During Pregnancy, Puerto Rico, USA, 2016-20171.

We examined pregnant women's use of personal protective measures to prevent mosquito bites during the 2016-2017 Zika outbreak in Puerto Rico. Healthcare provider counseling on recommended measures was associated with increased use of insect repellent among pregnant women but not with wearing protective clothing.

Influenza and Tdap Vaccination Coverage Among Pregnant Women - United States, April 2020.

Vaccination of pregnant women with influenza vaccine and tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine (Tdap) can decrease the risk for influenza and pertussis among pregnant women and their infants. The Advisory Committee on Immunization Practices (ACIP) recommends that all women who are or might be pregnant during the influenza season receive influenza vaccine, which can be administered at any time during pregnancy (1). ACIP also recommends that women receive Tdap during each pregnancy, preferably during the early part of gestational weeks 27-36 (2,3). Despite these recommendations, vaccination coverage among pregnant women has been found to be suboptimal with racial/ethnic disparities persisting (4-6). To assess influenza and Tdap vaccination coverage among women pregnant during the 2019-20 influenza season, CDC analyzed data from an Internet panel survey conducted during April 2020. Among 1,841 survey respondents who were pregnant anytime during October 2019-January 2020, 61.2% reported receiving influenza vaccine before or during their pregnancy, an increase of 7.5 percentage points compared with the rate during the 2018-19 season. Among 463 respondents who had a live birth by their survey date, 56.6% reported receiving Tdap during pregnancy, similar to the 2018-19 season (4). Vaccination coverage was highest among women who reported receiving a provider offer or referral for vaccination (influenza = 75.2%; Tdap = 72.7%). Compared with the 2018-19 season, increases in influenza vaccination coverage were observed during the 2019-20 season for non-Hispanic Black (Black) women (14.7 percentage points, to 52.7%), Hispanic women (9.9 percentage points, to 67.2%), and women of other non-Hispanic (other) races (7.9 percentage points, to 69.6%), and did not change for non-Hispanic White (White) women (60.6%). As in the 2018-19 season, Hispanic and Black women had the lowest Tdap vaccination coverage (35.8% and 38.8%, respectively), compared with White women (65.5%) and women of other races (54.0%); in addition, a decrease in Tdap vaccination coverage was observed among Hispanic women in 2019-20 compared with the previous season. Racial/ethnic disparities in influenza vaccination coverage decreased but persisted, even among women who received a provider offer or referral for vaccination. Consistent provider offers or referrals, in combination with conversations culturally and linguistically tailored for patients of all races/ethnicities, could increase vaccination coverage among pregnant women in all racial/ethnic groups and reduce disparities in coverage.
