Background: The COVID-19 pandemic in the United States is on-going and has impacted healthcare practices substantially. Consistent access to healthcare and, particularly, dialysis services are essential to the management of end stage renal disease (ESRD). The objective of this analysis was to examine patterns of outpatient hemodialysis utilization and outcomes of ESRD and COVID-19 in the 5 states with highest incidence of COVID-19 during the early stages of the pandemic. Methods: We used data from the Centers for Medicare and Medicaid Services (CMS) to examine trends in receipt of outpatient hemodialysis in 2019 and 2020 among Medicare beneficiaries with fee-for-service (FFS) coverage. Results: We found that average monthly hemodialysis rates for beneficiaries with ESRD without COVID-19 were stable over time at average monthly rates of between 2.5 and 2.8 sessions per person per week in both 2019 and 2020. Beneficiaries with COVID-19, both with and without pre-existing ESRD, had hemodialysis rates that varied monthly with an average of 2.5 sessions per week per person. Adjusted death rates were highest among beneficiaries with COVID-19 and pre-existing ESRD, followed by beneficiaries with COVID-19 and no pre-existing ESRD. There was little within-group variation in hemodialysis utilization by race/ethnicity but age- and sex- adjusted death rates varied considerably by racial and ethnic group. Conclusions: Dialysis facilities were able to provide hemodialysis sessions at typical rates despite challenges during the COVID-19 pandemic. However, patients with ESRD who contracted COVID-19 had remarkably high death rates, highlighting the need for ongoing efforts to protect at-risk populations from COVID-19.

Quality adolescent sexual and reproductive health (ASRH) services play an important role in supporting the overall health and well-being of adolescents. Improving access to this care can help reduce unintended pregnancies, sexually transmitted diseases (STDs), and human immunodeficiency virus (HIV) infection and their associated consequences, as well as promote health equity. The Centers for Disease Control and Prevention funded three grantees to implement a clinic-based ASRH quality improvement initiative complimented by activities to strengthen systems to refer and link youth to ASRH services. The purpose of this study is to describe the initiative and baseline assessment results of ASRH best practice implementation in participating health centers. The assessment found common use of the following practices: STD/HIV screening, education on abstinence and the use of dual protection, and activities to increase accessibility (e.g., offering after-school hours and walk-in and same-day appointments). The following practices were used less frequently: provider training for Long-Acting Reversible Contraception (LARC) insertion and removal, LARC availability, same-day provision of all contraceptive methods, and consistent sharing of information about confidentiality and minors' rights with adolescent clients. This study describes the types of training and technical assistance being implemented at each health center and discusses implications for future programming.

Background Affordability plays an important role in the utilisation of in vitro fertilisation (IVF) and non-IVF fertility treatments. Fertility treatments are associated with increased risk of multiple births. The objective of this study was to investigate the association between the affordability of fertility treatments across US states and the percentage of multiple births due to natural conception, non-IVF treatments, and IVF, and the association between these percentages and state-specific multiple birth rates. Methods State-specific per capita disposable personal income and state-specific infertility insurance mandates were used as measures of affordability. Maternal age-adjusted percentages of multiple births due to natural conception, non-IVF treatments, and IVF were estimated for each state using birth certificate and IVF data. Scatter plots and regression analysis were used to explore associations between state-level measures of affordability, the percentage of multiple births due to natural conception and fertility treatments, and state-specific multiple birth rates. Results In 2013, age-adjusted contributions of natural conception, non-IVF fertility treatments, and IVF to multiple births in US were 58.2, 22.8, and 19.0% respectively. States with greater affordability of fertility treatments had higher percentages of multiples due to IVF and lower percentages due to natural conception. Higher percentages of multiples due to IVF and lower percentages due to natural conception were associated with higher state-specific multiple birth rates. Conclusion Increasing affordability of fertility treatments may increase state-specific multiple birth rates. Policies and treatment practices encouraging single-gestation pregnancies may help reduce multiple births resulting from these treatments.

Introduction Diagnosis and control of chronic conditions have implications for women's health and are major contributing factors to maternal and infant morbidity and mortality. This study estimated the prevalence of hypertension and diabetes in non-pregnant women of reproductive age in the United States, the proportion who were unaware of their condition or whose condition was not controlled, and differences in the prevalence of these conditions by selected characteristics. Methods We used data from the 2011-2016 National Health and Nutrition Examination Survey to estimate overall prevalence of hypertension and diabetes among women of reproductive age (aged 20-44 y), the proportion who were unaware of having hypertension or diabetes, and the proportion whose diabetes or hypertension was not controlled. We used logistic regression models to calculate adjusted prevalence ratios to assess differences by selected characteristics. Results The estimated prevalence of hypertension was 9.3% overall. Among those with hypertension, 16.9% were unaware of their hypertension status and 40.7% had uncontrolled hypertension. Among women with diabetes, almost 30% had undiagnosed diabetes, and among those with diagnosed diabetes, the condition was not controlled in 51.5%. Conclusion This analysis improves our understanding of the prevalence of hypertension and diabetes among women of reproductive age and may facilitate opportunities to improve awareness and control of these conditions, reduce disparities in women's health, and improve birth outcomes.

Objectives To assess trends, predictors, and perinatal outcomes of ovarian hyperstimulation syndrome (OHSS) associated with in vitro fertilization (IVF) cycles in the United States. Design Retrospective cohort study using National Assisted Reproductive Technology Surveillance System (NASS) data. Setting Not applicable. Patient(s) Fresh autologous and embryo-banking cycles performed from 2000 to 2015. Interventions(s) None. Main Outcome Measure(s) OHSS, first-trimester loss, second-trimester loss, stillbirth, low birth weight, and preterm delivery. Result(s) The proportion of IVF cycles complicated by OHSS increased from 10.0 to 14.3 cases per 1,000 from 2000 to 2006, and decreased to 5.3 per 1,000 from 2006 to 2015. The risk of OHSS was highest for cycles with more than 30 oocytes retrieved (adjusted risk ratio [aRR] 3.85). OHSS was associated with a diagnosis of ovulatory disorder (aRR 2.61), tubal factor (aRR 1.14), uterine factor (aRR 1.17) and cycles resulting in pregnancy (aRR 3.12). In singleton pregnancies, OHSS was associated with increased risk of low birth weight (aRR 1.29) and preterm delivery (aRR 1.32). In twin pregnancies, OHSS was associated with an increased risk of second-trimester loss (aRR 1.81), low birth weight (aRR 1.06), and preterm delivery (aRR 1.16). Conclusion(s) Modifiable predictive factors for OHSS include number of oocytes retrieved, pregnancy following fresh embryo transfer, and the type of medication used for pituitary suppression during controlled ovarian hyperstimulation. Patients affected by OHSS had a higher risk of preterm delivery and low birth weight. Clinicians should take measures to reduce the risk of OHSS whenever possible.

Objective To investigate the associations among underweight body mass index (BMI), pregnancy, and obstetric outcomes among women using assisted reproductive technology (ART). Design Retrospective cohort study using national data and log binomial regression. Setting Not applicable. Patient(s) Women undergoing IVF in the United States from 2008 to 2013. Intervention(s) None. Main Outcome Measure(s) Pregnancy outcomes (intrauterine pregnancy, live birth rates) per transfer, miscarriage rate per pregnancy, and low birth weight and preterm delivery rates among singleton and twin pregnancies. Result(s) For all fresh autologous in vitro fertilization (IVF) cycles in the United States from 2008 to 2013 (n = 494,097 cycles, n=402,742 transfers, n=180,855 pregnancies) reported to the national ART Surveillance System, compared with normal weight women, underweight women had a statistically significant decreased chance of intrauterine pregnancy (adjusted risk ratio [aRR] 0.97; 95% confidence interval [CI], 0.96–0.99) and live birth (aRR 0.95; 95% CI, 0.93–0.98) per transfer. Obese women also had a statistically decreased likelihood of both (aRR 0.94; 95% CI, 0.94–0.95; aRR 0.87; 95% CI, 0.86–0.88, respectively). Among cycles resulting in singleton pregnancy, both underweight and obese statuses were associated with increased risk of low birth weight (aRR 1.39; 95% CI, 1.25–1.54, aRR 1.26; 95% CI, 1.20–1.33, respectively) and preterm delivery (aRR 1.12; 95% CI, 1.01–1.23, aRR 1.42; 95% CI, 1.36–1.48, respectively). The association between underweight status and miscarriage was not statistically significant (aRR 1.04; 95% CI, 0.98–1.11). In contrast, obesity was associated with a statistically significantly increased miscarriage risk (aRR 1.23; 95% CI, 1.20–1.26). Conclusion(s) Among women undergoing IVF, prepregnancy BMI affects pregnancy and obstetric outcomes. Underweight status may have a limited impact on pregnancy and live-birth rates, but it is associated with increased preterm and low-birth-weight delivery risk. Obesity negatively impacts all ART and obstetric outcomes investigated.

Objective To evaluate assisted reproductive technology (ART) ET practices in the United States and assess the impact of these practices on multiple births, which pose health risks for both mothers and infants. Design Retrospective cohort analysis using the National ART Surveillance System data. Setting US fertility centers reporting to the National ART Surveillance System. Patient(s) Noncanceled ART cycles conducted in the United States in 2012. Intervention(s) None. Main Outcome Measure(s) Multiple birth (birth of two or more infants, at least one of whom was live-born). Result(s) Of 134,381 ART transfer cycles performed in 2012, 51,262 resulted in live births, of which 13,563 (26.5%) were multiple births: 13,123 twin and 440 triplet and higher order births. Almost half (46.1%) of these multiple births resulted from the following four cycle types: two fresh blastocyst transfers among favorable or average prognosis patients less than 35 years (1,931 and 1,341 multiple births, respectively), two fresh blastocyst transfers among donor-oocyte recipients (1,532 multiple births), and two frozen/thawed ETs among patients less than 35 years (1,452 multiple births). More than half of triplet or higher order births resulted from the transfer of two embryos (52.5% of births among fresh autologous transfers, 67.2% of births among donor-oocyte recipient transfers, and 42.9% among frozen/thawed autologous transfers). Conclusion(s) A substantial reduction of ART-related multiple (both twin and triplet or higher order) births in the United States could be achieved by single blastocyst transfers among favorable and average prognosis patients less than 35 years of age and donor-oocyte recipients.

Background The advent of fertility treatments has led to an increase in the rate of multiple births in the United States. However, the trends in and magnitude of the contribution of fertility treatments to the increase are uncertain. Methods We derived the rates of multiple births after natural conception from data on distributions of all births from 1962 through 1966 (before fertility treatments were available). Publicly available data on births from 1971 through 2011 were used to determine national multiple birth rates, and data on in vitro fertilization (IVF) from 1997 through 2011 were used to estimate the annual proportion of multiple births that were attributable to IVF and to non-IVF fertility treatments, after adjustment for maternal age. Trends in multiple births were examined starting from 1998, the year when clinical practice guidelines for IVF were developed with an aim toward reducing the incidence of multiple births. Results We estimated that by 2011, a total of 36% of twin births and 77% of triplet and higher-order births resulted from conception assisted by fertility treatments. The observed incidence of twin births increased by a factor of 1.9 from 1971 to 2009. The incidence of triplet and higher-order births increased by a factor of 6.7 from 1971 to 1998 and decreased by 29% from 1998 to 2011. This decrease coincided with a 70% reduction in the transfer of three or more embryos during IVF (P

To examine health care burden, pregnancy outcomes and impact of high risk medical conditions among pregnancy hospitalizations during influenza season. Length of stay, hospitalization charges, and delivery complications were compared between hospitalizations with and without respiratory illness and compared by presence of high risk medical conditions. Length of stay and hospital charges were significantly increased among respiratory illness hospitalizations versus non-respiratory hospitalizations. Among respiratory illness hospitalization, the odds of intrauterine fetal demise were increased (adjusted odds ratio (aOR) 2.50, 95 % confidence interval (CI) 1.97–3.18). Among live births, there were higher odds of preterm delivery (aOR 3.82, 95 % CI 3.53–4.14), cesarean delivery (aOR 3.47, 95 % CI 3.22–3.74), and fetal distress (aOR 2.33, 95 % CI 2.15–2.52). The presence of high risk medical conditions did not impact pregnancy outcomes. Among pregnant women hospitalized during influenza season, those with respiratory illness were more likely than those without respiratory illness to have poor perinatal outcomes, regardless of the presence of high risk conditions. Efforts to minimize influenza morbidity, including universal vaccination and early antiviral therapy should be promoted among all pregnant women.

Background Studies point to variation in the effects of formal sex education on sexual behavior and contraceptive use by individual and community characteristics. Study design Using the 2002 National Survey of Family Growth, we explored associations between receipt of sex education and intercourse by age 15, intercourse by the time of the interview and use of effective contraception at first sex among 15-19-year-olds, stratified by quartiles of three community characteristics and adjusted for demographics. Results Across all quartiles of community characteristics, sex education reduced the odds of having sex by age 15. Sex education resulted in reduced odds of having sex by the date of the interview and increased odds of using contraception in the middle quartiles of community characteristics. Conclusion Variation in the effects of sex education should be explored. Research might focus on programmatic differences by community type and programmatic needs in various types of communities.

Objectives. We analyzed the health of Mexican American women aged 15 to 44 years, by generation and language preference, to guide planning for reproductive health services in this growing population. Methods. We used personal interview and medical examination data from the 1999 to 2004 National Health and Nutrition Examination Surveys. We used SUDAAN for calculating age-adjusted prevalence estimates of demographic and health characteristics. The Satterthwaite adjusted F test and Student t test were used for subgroup comparisons. Results. The women had different health profiles (P < .05) by generation and language preference. Second- and later-generation women and women who used more English were more likely to be sexually active, to have been younger at first intercourse, and to have had more male sexual partners than were first-generation women and women who used more Spanish. Compared with their first-generation counterparts, second- and later-generation women drank more alcohol, were better educated, had higher incomes, and were more likely to have health insurance. Third-generation women were more likely to have delivered a low-birthweight baby than were first-generation women. Conclusions. Differences by generation and language preference suggest that acculturation should be considered when planning interventions to promote healthy reproductive behaviors among Mexican American women.

Use of assisted reproductive technology (ART) continues to increase in the United States and globally. In an effort to improve patient safety, stimulation protocols have become less aggressive, oocyte retrieval has transitioned from laparoscopic to transvaginal, and pregnancy rates have improved.1 However, limited data exist regarding the incidence of maternal complications.2 We explored incidence and trends in reported patient and donor complications in fresh ART cycles using the US Centers for Disease Control and Prevention National ART Surveillance System (NASS).

To assess the association between number of embryos transferred and a measure of assisted reproductive technology success that emphasizes good perinatal outcome.We analyzed assisted reproductive technology cycles initiated in 2011 that progressed to fresh embryo transfer among women using autologous oocytes and reported to the U.S. National Assisted Reproductive Technology Surveillance System (n=82,508). Percentages of good perinatal outcome (live birth of a term [at or after 37 weeks of gestation], normal birth weight [2,500 g or greater] singleton) were stratified by prognosis (favorable, average, less favorable), age, embryo stage (day 3, day 5), and number of embryos transferred. Differences in the percentages by number of embryos transferred were evaluated using Fisher's exact test with Bonferroni correction.Among patients younger than 35 years with a favorable prognosis, chances of a good perinatal outcome were higher with transferring a single (compared with double) day 5 (43% compared with 27%) or day 3 embryo (36% compared with 30%). Likewise, a higher chance of a good perinatal outcome was observed with transferring a single day 5 embryo in patients 35-37 years old with a favorable prognosis (39% compared with 28%) or patients younger than 35 years old with an average prognosis (35% compared with 26%). A higher chance of good perinatal outcome was associated with transferring two (compared with one) day 3 embryos among patients aged 40 years or younger with an average prognosis or patients younger than 35 years old with a less favorable prognosis.The association between number of embryos transferred and the birth of a term, normal birth weight singleton is described. Among patients younger than 35 years of age undergoing in vitro fertilization with a favorable prognosis, the highest chance of good perinatal outcome is associated with a single embryo transfer.II.

Implantation and live birth rates resulting from IVF cycles using gonadotropin-releasing hormone (GnRH) agonist and (GnRH) antagonist IVF protocols were compared among good-prognosis patients using the Centers for Disease Control and Prevention's National Assisted Reproductive Technology Surveillance System 2009-2010 data (n = 203,302 fresh, autologous cycles). Bivariable and multivariable analyses were conducted between cycles to compare outcomes. Cycles were restricted as follows: age younger than 35 years, maximum FSH less than 10 mIU/mL, first assisted reproduction technology cycle and FSH dose less than 3601 IU. A subgroup analysis including only elective single embryo transfer was also carried out. Among good-prognosis patients, the GnRH-agonist protocol was associated with a lower risk of cancellation before retrieval (4.3 versus 5.2%; P < 0.05) or transfer (5.5 versus 6.8%; P < 0.05), and a higher live birth rate per transfer (adjusted odds ratio [OR] 1.13, confidence interval [CI] 1.03 to 1.25) than the GnRH-antagonist group. Among the elective single embryo transfer group, the GnRH-agonist protocol was associated with a higher implantation rate (adjusted odds ratio [OR] 1.36, CI 1.08 to 1.73) and a higher live birth rate (adjusted OR 1.33, CI 1.07 to 1.66) compared with the GnRH-antagonist protocol. The GnRH-antagonist group had lower rates of ovarian hyperstimulation syndrome. Among good-prognosis patients, agonist protocols decreased cancellation risk and increased odds of implantation and live birth. Antagonist protocols may confer decreased risk of hyperstimulation.

Florida resident birth certificates for 2004-2006 were linked to the Centers for Disease Control and Prevention's National ART Surveillance System and were used to investigate 1) whether the association of assisted reproductive technology (ART) with preterm birth varies by prepregnancy body mass index and 2) whether the association varies by plurality. Preterm birth was defined as early preterm birth (gestation

The objective of this study was to assess the relationship between body mass index (BMI) and epithelial ovarian cancer survival among young women.We conducted a cohort analysis of 425 women aged 20-54 years with incident epithelial ovarian cancer enrolled during 1980-1982 in Cancer and Steroid Hormone (CASH), a population-based, case-control study. Participants' vital status was ascertained though linkage with the Surveillance, Epidemiology and End Results (SEER) program. Using Cox proportional hazards models, we estimated adjusted hazard ratios (HR) and 95% confidence intervals (CI) for the association between survival and usual adult BMI, BMI at age 18, and weight change from age 18 to adult.During a follow-up of up to 17 years, 215 women died. Compared to women with an adult BMI in the lowest quartile (20.7), women in the second (20.8-22.5), third (22.6-24.9), and fourth (≥25.0) quartiles were not at increased risk for death (HR 1.2, 95% CI 0.8-1.8; HR 1.1, 95% CI 0.7-1.6; and HR 0.9, 95% CI 0.6-1.4, respectively) (p trend=0.6). Similarly, neither age 18 BMI nor weight change were associated with ovarian cancer survival.Although elevated BMI is associated with increased ovarian cancer risk among young women, we found no evidence of its association with ovarian cancer survival in this population.

To examine trends in rates of elective bilateral salpingo-oophorectomy in the United States and to assess the association of perioperative complications with elective bilateral salpingo-oophorectomy.This cross-sectional study uses 1998-2006 data from the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project, a nationally representative sample of inpatient hospitalizations. Analyses were limited to women aged 15 years or older at average risk for ovarian cancer who underwent hysterectomy for a benign gynecologic condition. Tests for trends in elective bilateral salpingo-oophorectomy rates were performed using weighted least squares regression for two time periods, 1998 to 2001 and 2002 to 2006. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for risks of complications associated with elective bilateral salpingo-oophorectomy were estimated using logistic regression.During the period from 1998 to 2006, 39% of the 2,250,041 women who underwent hysterectomy for benign gynecologic indications had elective bilateral salpingo-oophorectomy (rate, 8.3 per 10,000). The elective bilateral salpingo-oophorectomy rate increased from 7.8 per 10,000 in 1998 to 9.0 per 10,000 in 2001 (P trend.05) and decreased from 9.0 per 10,000 in 2002 to 7.4 per 10,000 in 2006 (P trend.05). The largest decline from 2002 to 2006 (20.3%) occurred among those aged 45 to 49 years. Compared with hysterectomy only, elective bilateral salpingo-oophorectomy was associated with an increased risk of complications when performed vaginally (OR 1.12; 95% CI 1.08-1.17) and a decreased risk of complications when performed abdominally (OR 0.91; 95% CI 0.89-0.94) or laparoscopically (OR 0.89; 95% CI 0.83-0.94).Elective bilateral salpingo-oophorectomy rates declined since 2002. However, the risks compared with the benefits of the procedure have not been clearly established. Prospective studies examining elective bilateral salpingo-oophorectomy with and without estrogen therapy are needed to guide practice patterns.III.

Introduction: Although many studies have examined the influence of reproductive factors on ovarian cancer risk, few have investigated their effect on ovarian cancer survival. We examined the prognostic influence of reproductive factors on survival after ovarian cancer diagnosis. Methods: We conducted a longitudinal analysis of 410women, ages 20 to 54 years, who participated in the 1980 to 1982 Cancer and Steroid Hormone study as incident ovarian cancer cases. We obtained their vital status by linking Cancer and Steroid Hormone records with Surveillance, Epidemiology, and End Results data. We used the Kaplan-Meier approach to estimate survival probabilities and Cox proportional hazards models to estimate hazard ratios (HR) and 95% confidence intervals (95% CI). Results: During a median follow-up of 9.2 years, 212women died. Of the reproductive factors examined, only age at menarche and number of lifetime ovulatory cycles (LOC) relative to age significantly predicted ovarian cancer survival. Risk for death was higher among women with highest number of LOC compared with those having fewest LOC (HR, 1.67; 95% CI, 1.20-2.33). Women with fewest LOC had the highest 15-year survival (56.7%; 95% CI, 47.8-64.6%), and women with the highest LOC had the poorest (33.3%; 95% CI, 25.3-41.5%). Women whose age at menarche was Conclusions: We found that high LOC and early age at menarche were associated with decreased survival after ovarian cancer.

Purpose Sex education is intended to provide youth with the information and skills needed to make healthy and informed decisions about sex. This study examined whether exposure to formal sex education is associated with three sexual behaviors: ever had sexual intercourse, age at first episode of sexual intercourse, and use of birth control at first intercourse. Methods Data used were from the 2002 National Survey of Family Growth, a nationally representative survey. The sample included 2019 never-married males and females aged 15–19 years. Bivariate and multivariate analyses were conducted using SUDAAN. Interactions among subgroups were also explored. Results Receiving sex education was associated with not having had sexual intercourse among males (OR = .42, 95% CI=.25–.69) and postponing sexual intercourse until age 15 among both females (OR = .41, 95% CI=.21–.77) and males (OR = .29, 95% CI=.17–.48). Males attending school who had received sex education were also more likely to use birth control the first time they had sexual intercourse (OR = 2.77, 95% CI=1.13–6.81); however, no associations were found among females between receipt of sex education and birth control use. These patterns varied among sociodemographic subgroups. Conclusions Formal sex education may effectively reduce adolescent sexual risk behaviors when provided before sexual initiation. Sex education was found to be particularly important for subgroups that are traditionally at high risk for early initiation of sex and for contracting sexually transmitted diseases.
