Intimate partner violence (IPV) can include emotional, physical, or sexual violence. IPV during pregnancy is a preventable cause of injury and death with negative short- and long-term impacts for pregnant women, infants, and families. Using data from the 2016-2022 Pregnancy Risk Assessment Monitoring System in nine U.S. jurisdictions, CDC examined associations between IPV during pregnancy among women with a recent live birth and the following outcomes: prenatal care initiation, health conditions during pregnancy (gestational diabetes, pregnancy-related hypertension, and depression), substance use during pregnancy, and infant birth outcomes. Overall, 5.4% of women reported IPV during pregnancy. Emotional IPV was most prevalent (5.2%), followed by physical (1.5%) and sexual (1.0%) IPV. All types were associated with delayed or no prenatal care; depression during pregnancy; cigarette smoking, alcohol use, marijuana or illicit substance use during pregnancy; and having an infant with low birth weight. Physical, sexual, and any IPV were associated with having a preterm birth. Physical IPV was associated with pregnancy-related hypertension. Evidence-based prevention and intervention strategies that address multiple types of IPV are important for supporting healthy parents and families because they might reduce pregnancy complications, depression and substance use during pregnancy, and adverse infant outcomes.

Problem/Condition CDC conducts abortion surveillance to document the number and characteristics of women obtaining legal induced abortions and the number of abortion-related deaths in the United States. Period Covered 2022. Description of System Each year, CDC requests abortion data from the central health agencies for the 50 states, the District of Columbia, and New York City. For 2022, a total of 48 reporting areas voluntarily provided aggregate abortion data to CDC. Of these, 47 reporting areas provided data each year during 2013–2022. Census and natality data were used to calculate abortion rates (number of abortions per 1,000 women aged 15–44 years) and ratios (number of abortions per 1,000 live births), respectively. Abortion-related deaths from 2021 were assessed as part of CDC’s Pregnancy Mortality Surveillance System (PMSS). Results For 2022, a total of 613,383 abortions were reported to CDC from 48 reporting areas. Among 47 reporting areas with data each year during 2013–2022, in 2022, a total of 609,360 abortions were reported, the abortion rate was 11.2 abortions per 1,000 women aged 15–44 years, and the abortion ratio was 199 abortions per 1,000 live births. From 2021 to 2022, the total number of abortions decreased 2% (from 622,108 total abortions), the abortion rate decreased 3% (from 11.6 abortions per 1,000 women aged 15–44 years), and the abortion ratio decreased 2% (from 204 abortions per 1,000 live births). From 2013 to 2022, the total number of reported abortions decreased 5% (from 640,154), the abortion rate decreased 10% (from 12.4 abortions per 1,000 women aged 15–44 years), and the abortion ratio increased 1% (from 198 abortions per 1,000 live births). In 2022, women in their 20s accounted for more than half of abortions (56.5%). Women aged 20–24 and 25–29 years accounted for the highest percentages of abortions (28.3% and 28.2%, respectively) and had the highest abortion rates (18.1 and 18.7 abortions per 1,000 women aged 20–24 and 25–29 years, respectively). By contrast, adolescents aged <15 years and women aged ≥40 years accounted for the lowest percentages of abortions (0.2% and 3.6%, respectively) and had the lowest abortion rates (0.4 and 2.5 abortions per 1,000 women aged <15 and ≥40 years, respectively). However, abortion ratios were highest among adolescents (aged ≤19 years) and lowest among women aged 30–39 years. From 2021 to 2022, abortion rates decreased among women aged ≥20 years and did not change among adolescents (aged ≤19 years). Abortion rates decreased from 2013 to 2022 among all age groups, except women aged 30–34 years for whom it increased. The decrease in the abortion rate from 2013 to 2022 was highest among adolescents compared with other age groups. From 2021 to 2022, abortion ratios increased for adolescents and decreased among women aged ≥20 years. From 2013 to 2022, abortion ratios increased among adolescents and women aged 20–34 years and decreased among women aged ≥35 years. In 2022, the majority (78.6%) of abortions were performed at ≤9 weeks’ gestation, and nearly all (92.8%) were performed at ≤13 weeks’ gestation. During 2013–2022, the percentage of abortions performed at >13 weeks’ gestation remained low (≤8.7%). In 2022, the highest percentage of abortions were performed by early medication abortion at ≤9 weeks’ gestation (53.3%), followed by surgical abortion at ≤13 weeks’ gestation (35.5%), surgical abortion at >13 weeks’ gestation (6.9%), and medication abortion at >9 weeks’ gestation (4.3%); all other methods were uncommon (<0.1%). Among those that were eligible (≤9 weeks’ gestation), 70.2% of abortions were early medication abortions. In 2021, the most recent year for which PMSS data were reviewed for pregnancy-related deaths, five women died as a result of complications from legal induced abortions. Interpretation Among the 47 areas that reported data continuously during 2013–2022, overall decreases were observed over this time in the number and rate of reported abortions and an increase was observed in the abortion ratio; in addition, from 2021 to 2022, decreases of 2%–3% were observed across all measures. Public Health Action Abortion surveillance can be used to help evaluate programs aimed at promoting equitable access to patient-centered quality contraceptive services in the United States to reduce unintended pregnancies.

The 2024 U.S. Medical Eligibility Criteria for Contraceptive Use (U.S. MEC) comprises recommendations for the use of specific contraceptive methods by persons who have certain characteristics or medical conditions. These recommendations for health care providers were updated by CDC after review of the scientific evidence and a meeting with national experts in Atlanta, Georgia, during January 25–27, 2023. The information in this report replaces the 2016 U.S. MEC (CDC. U.S. Medical Eligibility Criteria for Contraceptive Use, 2016. MMWR 2016:65[No. RR-3]:1–103). Notable updates include 1) the addition of recommendations for persons with chronic kidney disease; 2) revisions to the recommendations for persons with certain characteristics or medical conditions (i.e., breastfeeding, postpartum, postabortion, obesity, surgery, deep venous thrombosis or pulmonary embolism with or without anticoagulant therapy, thrombophilia, superficial venous thrombosis, valvular heart disease, peripartum cardiomyopathy, systemic lupus erythematosus, high risk for HIV infection, cirrhosis, liver tumor, sickle cell disease, solid organ transplantation, and drug interactions with antiretrovirals used for prevention or treatment of HIV infection); and 3) inclusion of new contraceptive methods, including new doses or formulations of combined oral contraceptives, contraceptive patches, vaginal rings, progestin-only pills, levonorgestrel intrauterine devices, and vaginal pH modulator. The recommendations in this report are intended to serve as a source of evidence-based clinical practice guidance for health care providers. The goals of these recommendations are to remove unnecessary medical barriers to accessing and using contraception and to support the provision of person-centered contraceptive counseling and services in a noncoercive manner. Health care providers should always consider the individual clinical circumstances of each person seeking contraceptive services. This report is not intended to be a substitute for professional medical advice for individual patients; when needed, patients should seek advice from their health care providers about contraceptive use.

The 2024 U.S. Selected Practice Recommendations for Contraceptive Use (U.S. SPR) addresses a selected group of common, yet sometimes complex, issues regarding initiation and use of specific contraceptive methods. These recommendations for health care providers were updated by CDC after review of the scientific evidence and a meeting with national experts in Atlanta, Georgia, during January 25–27, 2023. The information in this report replaces the 2016 U.S. SPR (CDC. U.S. Selected Practice Recommendations for Contraceptive Use, 2016. MMWR 2016;65[No. RR-4]:1–66). Notable updates include 1) updated recommendations for provision of medications for intrauterine device placement, 2) updated recommendations for bleeding irregularities during implant use, 3) new recommendations for testosterone use and risk for pregnancy, and 4) new recommendations for self-administration of injectable contraception. The recommendations in this report are intended to serve as a source of evidence-based clinical practice guidance for health care providers.

Objectives. To describe breastfeeding initiation and breastfeeding at 1, 2, and 3 months, and information sources on breastfeeding among women with a recent live birth by disability status. Methods. We analyzed October 2018 to December 2020 data from the Pregnancy Risk Assessment Monitoring System for 24 sites in the United States that included the Washington Group Short Set of Questions on Disability (seeing, hearing, walking or climbing stairs, remembering or concentrating, self-care, communicating). We defined disability as reporting “a lot of difficulty” or “cannot do this at all” on any of these questions. Results. Among 39 673 respondents, 6.0% reported disability. In adjusted analyses, breastfeeding was lower among respondents with disability at 2 (62.6% vs 66.6%; adjusted prevalence ratio [APR] = 0.94; 95% confidence interval [CI] = 0.89, 0.99) and 3 months (54.7% vs 59.6%; APR = 0.92; 95% CI = 0.86, 0.98) than those without disability. Respondents with disability were less likely to receive information from health care providers or support professionals (89.3% vs 92.3%), but as likely from breastfeeding or lactation specialists (78.1% vs 75.3%). Conclusions. Strategies to ensure women with disability, receive breastfeeding support, including breastfeeding information, could improve breastfeeding outcomes.

Purpose: We examined the impact of the COVID-19 pandemic in Fall 2021 on sexual and reproductive health (SRH) services among physicians whose practice provided these services to adolescents just before the pandemic. Methods: Data were from the DocStyles online panel survey administered September-November 2021 to US physicians who reported their practice provided SRH services to adolescent patients before the pandemic (n = 948). We calculated prevalence of service delivery challenges (e.g., limited long-acting reversible contraception services) and use of strategies to support access (e.g., telehealth) in the month prior to survey completion, compared these estimates with prevalence "at any point during the COVID-19 pandemic", and examined differences by physician specialty and adolescent patient volume. Results: Fewer physicians reported their practice experienced service delivery challenges in the month prior to survey completion than at any point during the pandemic. About 10% indicated limited long-acting reversible contraception and sexually transmitted infection testing services in the prior month overall; prevalence varied by physician specialty (e.g., 26% and 17%, respectively by service, among internists). Overall, about 25% of physicians reported reductions in walk-in hours, weekend/evening hours, and adolescents seeking care in the prior month. While most practices that initiated strategies supporting access to services during the pandemic used such strategies in the prior month, some practices (22%-37% depending on the strategy) did not. Discussion: Findings suggest some physicians who serve adolescents continued to experience challenges providing SRH services in the Fall 2021, and some discontinued strategies to support access that had been initiated during the pandemic.

Problem/condition: CDC conducts abortion surveillance to document the number and characteristics of women obtaining legal induced abortions and number of abortion-related deaths in the United States. Period covered: 2020. Description of system: Each year, CDC requests abortion data from the central health agencies for the 50 states, the District of Columbia, and New York City. For 2020, a total of 49 reporting areas voluntarily provided aggregate abortion data to CDC. Of these, 48 reporting areas provided data each year during 2011-2020. Census and natality data were used to calculate abortion rates (number of abortions per 1,000 women aged 15-44 years) and ratios (number of abortions per 1,000 live births), respectively. Abortion-related deaths from 2019 were assessed as part of CDC's Pregnancy Mortality Surveillance System (PMSS). Results: A total of 620,327 abortions for 2020 were reported to CDC from 49 reporting areas. Among 48 reporting areas with data each year during 2011-2020, in 2020, a total of 615,911 abortions were reported, the abortion rate was 11.2 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 198 abortions per 1,000 live births. From 2019 to 2020, the total number of abortions decreased 2% (from 625,346 total abortions), the abortion rate decreased 2% (from 11.4 abortions per 1,000 women aged 15-44 years), and the abortion ratio increased 2% (from 195 abortions per 1,000 live births). From 2011 to 2020, the total number of reported abortions decreased 15% (from 727,554), the abortion rate decreased 18% (from 13.7 abortions per 1,000 women aged 15-44 years), and the abortion ratio decreased 9% (from 217 abortions per 1,000 live births).In 2020, women in their 20s accounted for more than half of abortions (57.2%). Women aged 20-24 and 25-29 years accounted for the highest percentages of abortions (27.9% and 29.3%, respectively) and had the highest abortion rates (19.2 and 19.0 abortions per 1,000 women aged 20-24 and 25-29 years, respectively). By contrast, adolescents aged <15 years and women aged ≥40 years accounted for the lowest percentages of abortions (0.2% and 3.7%, respectively) and had the lowest abortion rates (0.4 and 2.6 abortions per 1,000 women aged <15 and ≥40 years, respectively). However, abortion ratios were highest among adolescents (aged ≤19 years) and lowest among women aged 25-39 years.Abortion rates decreased from 2011 to 2020 among all age groups. The decrease in abortion rate was highest among adolescents compared with any other age group. From 2019 to 2020, abortion rates decreased or did not change for all age groups. Abortion ratios decreased from 2011 to 2020 for all age groups, except adolescents aged 15-19 years and women aged 25-29 years for whom abortion ratios increased. The decrease in abortion ratio was highest among women aged ≥40 years compared with any other age group. From 2019 to 2020, abortion ratios decreased for adolescents aged <15 years and women aged ≥35 and increased for women 15-34 years.In 2020, 80.9% of abortions were performed at ≤9 weeks' gestation, and nearly all (93.1%) were performed at ≤13 weeks' gestation. During 2011-2020, the percentage of abortions performed at >13 weeks' gestation remained consistently low (≤9.2%). In 2020, the highest percentage of abortions were performed by early medical abortion at ≤9 weeks' gestation (51.0%), followed by surgical abortion at ≤13 weeks' gestation (40.0%), surgical abortion at >13 weeks' gestation (6.7%), and medical abortion at >9 weeks' gestation (2.4%); all other methods were uncommon (<0.1%). Among those that were eligible (≤9 weeks' gestation), 63.9% of abortions were early medical abortions. In 2019, the most recent year for which PMSS data were reviewed for pregnancy-related deaths, four women died as a result of complications from legal induced abortion. Interpretation: Among the 48 areas that reported data continuously during 2011-2020, overall decreases were observed during 2011-2020 in the total number, rate, and ratio of reported abortions. From 2019 to 2020, decreases also were observed in the total number and rate of reported abortions; however, a 2% increase was observed in the total abortion ratio. Public health action: Abortion surveillance can be used to help evaluate programs aimed at promoting equitable access to patient-centered quality contraceptive services in the United States to reduce unintended pregnancies.
