Cigarette Smoking Among Pregnant Women During the Perinatal Period: Prevalence and Health Care Provider Inquiries - Pregnancy Risk Assessment Monitoring System, United States, 2021.

Cigarette smoking during pregnancy increases the risk for pregnancy complications and adverse infant outcomes such as preterm delivery, restricted fetal growth, and infant death. Health care provider counseling can support smoking cessation. Data from the 2021 Pregnancy Risk Assessment Monitoring System were analyzed to estimate the prevalence of smoking before, during, and after pregnancy; quitting smoking during pregnancy; and whether health care providers asked about cigarette smoking before, during, and after pregnancy among women with a recent live birth. In 2021, the prevalence of cigarette smoking was 12.1% before pregnancy, 5.4% during pregnancy, and 7.2% during the postpartum period; 56.1% of women who smoked before pregnancy quit smoking while pregnant. Jurisdiction-specific prevalences of smoking ranged from 3.5% to 20.2% before pregnancy, 0.4% to 11.0% during pregnancy, and 1.0% to 15.1% during the postpartum period. Among women with a health care visit during the associated period, the percentage of women who reported that a health care provider asked about smoking was 73.7% at any health care visit before pregnancy, 93.7% at any prenatal care visit, and 57.3% at a postpartum checkup. Routine assessment of smoking behaviors among pregnant and postpartum women can guide the development and implementation of evidence-based tobacco control measures at the jurisdiction and health care-system level to reduce smoking among pregnant and postpartum women.

The use of fertility treatments among reproductive-aged women after cancer.

OBJECTIVE: To examine whether female cancer survivors are more likely to pursue care for infertility after cancer than women without cancer. DESIGN: Population-based cohort study involving detailed interviews regarding reproductive history. SETTING: Not applicable. PATIENTS: Female cancer survivors aged 22-45 years, who were at least 2 years after a cancer diagnosis between the ages of 20 and 35 years (n = 1,036), and age-matched comparison women with no cancer history (n = 1,026). EXPOSURE: History of cancer vs. no history of cancer. MAIN OUTCOME MEASURE(S): Each cancer survivor was randomly matched to a comparison woman, who was assigned an artificial age at cancer diagnosis equal to that of her match. Matching was repeated 1,000 times. Outcomes of visiting a doctor for help becoming pregnant or undergoing fertility treatment were modeled using Cox proportional hazards regression, comparing survivors after a cancer diagnosis to age-matched comparison women, adjusted for race, income, residence, education, and parity. RESULTS: Only 25.5% of cancer survivors reported meeting their desired family size before a cancer diagnosis. The median time from diagnosis to interview among survivors was 7 (interquartile range 5-11) years. Cancer survivors were more likely to report having no children (32.6%) at the interview compared with women with no cancer history (19.5%). Survivors were not more likely to visit a doctor for help becoming pregnant compared with women without a cancer history, matched on birth year and followed by the age at which cancer survivors received their diagnosis (hazard ratio [HR] 1.16, 95% simulation interval [SI] 0.78-1.74). Compared with cancer-free women, cancer survivors had similar probabilities of pursuing any treatment (adjusted HR [aHR] 0.88, 95% SI 0.46-1.56), using hormones or medications (aHR 0.86, 95% SI 0.46-1.63), or undergoing intrauterine insemination (aHR 1.26, 95% SI 0.40-5.88) to conceive. Cancer survivors were slightly more likely to pursue surgical interventions to become pregnant (HR 1.55, 95% SI 0.67-3.71). Of those who visited a doctor but declined to pursue fertility treatment, one-quarter of women reported declining treatment due to cost. CONCLUSION: Cancer survivors did not use fertility treatments at higher rates than the general population. Further counseling and education surrounding fertility options are recommended for young adult female cancer patients after treatment is completed.

Vital Signs: Maternity Care Experiences - United States, April 2023.

Introduction: Maternal deaths increased in the United States during 2018-2021, with documented racial disparities. Respectful maternity care is a component of quality care that includes preventing harm and mistreatment, engaging in effective communication, and providing care equitably. Improving respectful maternity care can be part of multilevel strategies to reduce pregnancy-related deaths. Methods: CDC analyzed data from the PN View Moms survey administered during April 24-30, 2023, to examine the following components of respectful care: 1) experiences of mistreatment (e.g., violations of physical privacy, ignoring requests for help, or verbal abuse), 2) discrimination (e.g., because of race, ethnicity or skin color; age; or weight), and 3) reasons for holding back from communicating questions or concerns during maternity (pregnancy or delivery) care. Results: Among U.S. mothers with children aged <18 years, 20% reported mistreatment while receiving maternity care for their youngest child. Approximately 30% of Black, Hispanic, and multiracial respondents and approximately 30% of respondents with public insurance or no insurance reported mistreatment. Discrimination during the delivery of maternity care was reported by 29% of respondents. Approximately 40% of Black, Hispanic, and multiracial respondents reported discrimination, and approximately 45% percent of all respondents reported holding back from asking questions or discussing concerns with their provider. Conclusions and implications for public health practice: Approximately one in five women reported mistreatment during maternity care. Implementing quality improvement initiatives and provider training to encourage a culture of respectful maternity care, encouraging patients to ask questions and share concerns, and working with communities are strategies to improve respectful maternity care.

The Risk of Infertility After Surgery for Benign Ovarian Cysts.

Background: There is a growing body of evidence that ovarian cystectomy may negatively impact ovarian reserve. However, it is unclear whether ovarian cyst surgery puts women at risk of future infertility. This study investigates whether surgery for benign ovarian cysts is associated with long-term infertility risk. Methods: Women aged 22-45 years (n = 1,537) were invited to participate in an interview about their reproductive histories, including whether they ever had infertility or ovarian cyst surgery. Each woman reporting cyst surgery was randomly matched to a comparison woman, who was assigned an artificial surgery age equal to that of her match. Matching was repeated 1,000 times. Adjusted Cox models were fit to examine time to infertility after surgery for each match. A subset of women was invited to participate in a clinic visit to assess markers of ovarian reserve (anti-Müllerian hormone [AMH], antral follicle count). Results: Approximately 6.1% of women reported cyst surgery. Infertility after surgery was more common for women reporting cyst surgery than those without surgery after adjusting for age, race, body mass index, cancer history, parity before assigned surgery age, history of infertility before surgery age, and endometriosis (median-adjusted hazard ratio 2.41, 95% simulation interval 1.03-6.78). The estimated geometric mean (95% confidence interval [CI]) AMH levels of those who reported a history of ovarian cyst surgery were 1.08 (95% CI: 0.57-2.05) times those of women who reported no history of surgery. Conclusions: Those with a history of ovarian cyst surgery were more likely to report having a history of infertility compared with age-matched women who reported no history of cyst surgery. It is possible that both ovarian surgery to remove cysts and the conditions that lead women to develop cysts requiring surgery may affect subsequent successful conception.

Potential misclassification of diabetes and prediabetes in the U.S.: Mismatched HbA1c and glucose in NHANES 2005-2016.

AIMS: To assess the prevalence and clinical implications of "mismatches" between HbA1c and glucose levels in the United States across the life course. METHODS: Participants ages 12-79 years from U.S. National Health and Nutrition Examination Survey (NHANES) 2005-2016 without known diagnosis of diabetes and who had a 75 g oral glucose tolerance test were included. Previously undiagnosed diabetes (DM), prediabetes, and normal glucose metabolism (NGM) were defined using American Diabetes Association cut-points. Mismatches were defined by the hemoglobin glycation index (HGI). RESULTS: In 10,361 participants, 5% and 41% had diabetes and prediabetes, respectively, by fasting or 2-hour glucose criteria. By HbA1c criteria, the high HGI tertile consisted of mostly abnormal classification (3% DM, 52% prediabetes) and the low HGI tertile contained mostly normal classification (78% NGM). Across all ages, 15% (weighted: 30 million individuals) had clinically significant mismatches of HGI magnitude ≥+0.5% (i.e., high mismatch) or ≤-0.5% (low mismatch). Mismatch was most common in older adults and non-Hispanic Black participants. CONCLUSIONS: Mismatches of clinically significant magnitude could lead to HbA1c-related misdiagnosis or inappropriate management in up to 30 million Americans. Older adults, non-Hispanic Black individuals, and others with high mismatches may benefit from complementing HbA1c with additional diagnostic and management strategies.

Factors Associated with Unplanned Pregnancy Among Cancer Survivors.

Background: Approximately half of all pregnancies in the United States are unintended. However, women who are diagnosed with cancer in their reproductive years may be a unique population. This study examines the prevalence of and identifies factors associated with unplanned pregnancy among cancer survivors. Materials and Methods: Female cancer survivors aged 22-45 years, diagnosed between ages 20-35 years and at least 2 years postdiagnosis, and women with no history of cancer were interviewed about their reproductive histories, including pregnancy intention. Using a random matching process, comparison women were assigned an artificial age at cancer diagnosis equal to that of her cancer survivor match. An adjusted Cox model was fit examining time to unintended pregnancy after cancer for each of 1,000 matches. Cox proportional hazards models were also fit to assess associations between participant characteristics and unplanned pregnancy after cancer among survivors. Results: Cancer survivors (n = 1,282) and comparison women (n = 1,073) reported a similar likelihood of having an unplanned pregnancy in models adjusted for race, income, history of sexually-transmitted infection, and history of unplanned pregnancy before diagnosis (adjusted hazard ratio [aHR] 1.06, 95% simulation interval 0.85-1.36). After adjusting for confounders, unplanned pregnancy among survivors was associated with age <30 years at diagnosis (hazard ratio [HR]: 1.79, 95% confidence interval [CI]: 1.32-2.44), black race (HR: 1.55, 95% CI: 1.13-2.12; referent: white), receiving fertility counseling (aHR: 1.41, 95% CI: 1.04-1.92), and having at least one child before diagnosis (aHR: 1.44, 95% CI: 1.05-1.97). Conclusion: Cancer survivors and comparison women had similar likelihood of unplanned pregnancy. Rates of unplanned pregnancy after cancer were not higher for cancer survivors compared with comparison women, but 46.4% of survivors with a postcancer pregnancy reported an unplanned pregnancy. Cancer patients may benefit from patient-centered guidelines and counseling before cancer treatment that covers both risks of infertility and risks of unplanned pregnancy.

Influence of Paternal Race on Characteristics and Outcomes of Assisted Reproductive Technologies.

OBJECTIVE: To investigate the association between paternal race and reproductive outcomes following in vitro fertilization (IVF). MATERIALS AND METHODS: We compared demographic and clinical characteristics, IVF cycle characteristics, and reproductive outcomes (pregnancy, miscarriage, and live birth), stratified by male and female partner race, for all IVF cycles performed at our institution between 2014 and 2019. Wilcoxon Rank Sum test and Pearson's Chi Square test were used to compare continuous and categorical data, respectively. A Poisson regression model was used to determine the association between race and clinical outcomes. Significance was set as P <.05. RESULTS: We examined 1878 IVF cycles involving 1069 couples. The study population was diverse; 50.1% of male partners were white, 28.5% black, 15.1% Asian, and 2.3% Hispanic. The majority of couples (86.5%) shared a common self-reported race category. Black males were older than white males (39.6 vs 37.0 years), with higher BMI (30.4 vs 28.0) and higher frequency of male factor infertility (45.9% vs 33.5%). Female partners of black males were older than those of white males (35.6 vs 33.8 years), with higher BMI (29.6 vs 25.2), and higher frequency of female factor infertility (91.8% vs 83.9%). Although we noted race-related variability in IVF cycle characteristics, no significant differences in the outcomes of pregnancy, biochemical pregnancy, clinical intrauterine pregnancy, or ectopic pregnancy were observed between races. CONCLUSION: Although paternal race was associated with IVF cycle characteristics, after controlling for potential confounders, paternal race did not independently contribute to outcomes in this institutional dataset.

Urinary and salivary endocrine measurements to complement Tanner staging in studies of pubertal development.

BACKGROUND: Many studies investigating pubertal development use Tanner staging to assess maturation. Endocrine markers in urine and saliva may provide an objective, sensitive, and non-invasive method for assessing development. OBJECTIVE: Our objective was to examine whether changes in endocrine levels can indicate the onset of pubertal development prior to changes in self-rated Tanner stage. METHODS: Thirty-five girls and 42 boys aged 7 to 15 years were enrolled in the Growth and Puberty (GAP) study, a longitudinal pilot study conducted from 2007-2009 involving children of women enrolled in the Agricultural Health Study (AHS) in Iowa. We collected saliva and urine samples and assessed pubertal development by self-rated Tanner staging (pubic hair, breast development (girls), genital development (boys)) at three visits over six months. We measured dehydroepiandrosterone (DHEA) in saliva and creatinine-adjusted luteinizing hormone (LH), testosterone, follicle stimulating hormone (FSH), estrone 3-glucuronide (E13G) and pregnanediol 3-glucuronide (Pd3G) concentrations in first morning urine. We evaluated the relationships over time between Tanner stage and each biomarker using repeated measures analysis. RESULTS: Among girls still reporting Tanner breast stage 1 at the final visit, FSH levels increased over the 6-month follow-up period and were no longer lower than higher stage girls at the end of follow-up. We observed a similar pattern for testosterone in boys. By visit 3, boys still reporting Tanner genital stage 1 or pubic hair stage 1 had attained DHEA levels that were comparable to those among boys reporting Tanner stages 2 or 3. CONCLUSIONS: Increasing concentrations of FSH in girls and DHEA and testosterone in boys over a 6-month period revealed the start of the pubertal process prior to changes in self-rated Tanner stage. Repeated, non-invasive endocrine measures may complement the more subjective assessment of physical markers in studies determining pubertal onset.

Influence of paternal age on assisted reproductive technology cycles and perinatal outcomes.

OBJECTIVE: To characterize paternal age among assisted reproductive technology (ART) cycles performed in the United States and to evaluate the influence of paternal age on ART cycles and perinatal outcomes. DESIGN: Retrospective cohort. SETTING: Not applicable. PATIENT(S): All reported fresh, nondonor, noncancelled in vitro fertilization (IVF) cycles performed in 2017. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): The primary outcomes were intrauterine pregnancy, live birth (≥20 weeks), and miscarriage (<20 weeks) per cycle start and per embryo transfer. The secondary outcomes were full-term live birth (≥37 weeks) among singleton and twin gestations. Modified Poisson regression was performed to estimate associations between paternal age and cycle and perinatal outcomes, overall and stratified by maternal age. RESULT(S): Among 77,209 fresh nondonor, noncancelled IVF cycles, the average paternal age was 37.8 ± 6.3 years and the average maternal age was 35.5 ± 4.6 years. Compared with paternal age ≤45 years, paternal age ≥46 years was associated with a lower likelihood of pregnancy per cycle (adjusted risk ratio [aRR] 0.81; 95% confidence interval [CI] 0.76-0.87) and per transfer (aRR 0.85; 95% CI 0.81-0.90), as well as a lower likelihood of live birth per cycle (aRR 0.76; 95% CI 0.72-0.84) and per transfer (aRR 0.82; 95% CI 0.77-0.88) after controlling for maternal age and other confounders. When restricted to women aged <35 years, there were no significant differences in the rates of live birth or miscarriage among couples in which the men were aged ≤45 years compared with those aged ≥46 years. CONCLUSION(S): Compared with paternal age ≤45 years, paternal age ≥46 years is associated with a lower likelihood of pregnancy and live birth among couples undergoing IVF. The negative effect of paternal age is most notable among women aged ≥35 years, likely because maternal age is a stronger predictor of ART outcome.

Enhanced antibiotic prophylaxis and infection-related complications following prostate biopsy.

PURPOSE: Sepsis after prostate biopsy is a costly and potentially lethal complication. We sought to assess whether enhanced antibiotic prophylaxis regimens combining oral and parenteral antibiotics may decrease the risk of post-biopsy urinary tract infection and sepsis compared to regimens with only oral antibiotics. METHODS: We identified men with commercial insurance who underwent prostate biopsy (2009-2015) with prophylactic antibiotic coverage. Our primary exposure of interest was antibiotic regimen: enhanced, oral-only, and parenteral-only. Post-biopsy outcomes of interest included urinary tract infections and sepsis/bacteremia after prostate biopsy. We used bivariate testing to assess associations between outcomes, exposures, and other covariates of interest. Multivariable regression was used to estimate adjusted odds of infectious outcomes based on antibiotic regimen. RESULTS: We identified 163,831 men who underwent prostate biopsy. The proportion of men with infectious complications (5.5% in 2009 to 6.9% in 2015, p < 0.001) and sepsis (0.24% in 2009 to 0.30% in 2015, p = 0.327) increased over the timeframe of our analysis. Use of fluoroquinolones was associated with a decreased risk of infectious outcomes (5.8 vs 7.3% without, OR 0.83, 95% CI 0.79-0.88). Use of enhanced antibiotic regimens was associated with an increased risk of infectious outcomes (6.8 vs 5.7% oral, OR 1.23, 95% CI 1.16-1.31) and sepsis (0.34 vs 0.24% oral, OR 1.40, 95% CI 1.08-1.82) among our cohort. CONCLUSION: We did not observe a significant reduction in infectious complications among men who received enhanced antibiotics regimens before prostate biopsy. This may be due to increased antibiotic resistance or unmeasured risk factors among those receiving enhanced regimens.

Comparison of diameter-based and image-based measures of surface area from gross placental pathology for use in epidemiologic studies.

Placental surface area is often estimated using diameter measurements. However, as many placentas are not elliptical, we were interested in the validity of these estimates. We compared placental surface area from images for 491 singletons from the Stillbirth Collaborative Research Network (SCRN) Study (416 live births, 75 stillbirths) to estimates obtained using diameter measurements. Placental images and diameters were obtained from pathologic assessments conducted for the SCRN Study and images were analyzed using ImageJ software. On average, diameter-based measures underestimated surface area by -5.58% (95% confidence interval: -30.23, 19.07); results were consistent for normal and abnormal shapes. The association between surface area and birthweight was similar for both measures. Thus, diameter-based surface area can be used to estimate placental surface area.
