Disparities in COVID-19 Hospitalization at the Intersection of Race and Ethnicity and Income.

BACKGROUND: Existing studies have elucidated racial and ethnic disparities in COVID-19 hospitalizations, but few have examined disparities at the intersection of race and ethnicity and income. METHODS: We used a population-based probability survey of non-institutionalized adults in Michigan with a polymerase chain reaction-positive SARS-CoV-2 test before November 16, 2020. We categorized respondents by race and ethnicity and annual household income: low-income (< $50,000) Non-Hispanic (NH) Black, high-income (≥ $50,000) NH Black, low-income Hispanic, high-income Hispanic, low-income NH White, and high-income NH White. We used modified Poisson regression models, adjusting for sex, age group, survey mode, and sample wave, to estimate COVID-19 hospitalization prevalence ratios by race and ethnicity and income. RESULTS: Over half of the analytic sample (n = 1593) was female (54.9%) and age 45 or older (52.5%), with 14.5% hospitalized for COVID-19. Hospitalization was most prevalent among low-income (32.9%) and high-income (31.2%) Non-Hispanic (NH) Black adults, followed by low-income NH White (15.3%), low-income Hispanic (12.9%), high-income NH White (9.6%), and high-income Hispanic adults (8.8%). In adjusted models, NH Black adults, regardless of income (low-income prevalence ratio [PR]: 1.86, 95% CI: 1.36-2.54; high-income PR: 1.57, 95% CI: 1.07-2.31), and low-income NH White adults (PR: 1.52, 95% CI: 1.12-2.07), had higher prevalence of hospitalization compared to high-income NH White adults. We observed no significant difference in the prevalence of hospitalization among Hispanic adults relative to high-income NH White adults. CONCLUSIONS: We observed disparities in COVID-19 hospitalization at the intersection of race and ethnicity and income for NH Black adults and low-income NH White adults relative to high-income NH White adults, but not for Hispanic adults.

Patterns and predictors of depressive and anxiety symptoms within a population-based sample of adults diagnosed with COVID-19 in Michigan.

PURPOSE: The COVID-19 pandemic has had wide-ranging impacts on mental health, however, less is known about predictors of mental health outcomes among adults who have experienced a COVID-19 diagnosis. We examined the intersection of demographic, economic, and illness-related predictors of depressive and anxiety symptoms within a population-based sample of adults diagnosed with COVID-19 in the U.S. state of Michigan early in the pandemic. METHODS: Data were from a population-based survey of Michigan adults who experienced a COVID-19 diagnosis prior to August 1, 2020 (N = 1087). We used weighted prevalence estimates and multinomial logistic regression to examine associations between mental health outcomes (depressive symptoms, anxiety symptoms, and comorbid depressive/anxiety symptoms) and demographic characteristics, pandemic-associated changes in accessing basic needs (accessing food/clean water and paying important bills), self-reported COVID-19 symptom severity, and symptom duration. RESULTS: Relative risks for experiencing poor mental health outcomes varied by sex, age, race/ethnicity, and income. In adjusted models, experiencing a change in accessing basic needs associated with the pandemic was associated with higher relative risks for anxiety and comorbid anxiety/depressive symptoms. Worse COVID-19 symptom severity was associated with a higher burden of comorbid depressive/anxiety symptoms. "Long COVID" (symptom duration greater than 60 days) was associated with all outcomes. CONCLUSION: Adults diagnosed with COVID-19 may face overlapping risk factors for poor mental health outcomes, including pandemic-associated disruptions to household and economic wellbeing, as well as factors related to COVID-19 symptom severity and duration. An integrated approach to treating depressive/anxiety symptoms among COVID-19 survivors is warranted.

Lack of access to personal protective equipment is associated with severe COVID-19 symptoms among in-person workers.

The use of personal protective equipment (PPE) at work can greatly reduce risk of SARS-CoV-2 transmission. However, it is unclear whether adequate PPE reduces disease severity if transmission occurs. This study investigated associations between workplace access to adequate PPE and self-reported COVID-19 symptom severity among in-person workers. We used data from the Michigan COVID-19 Recovery Surveillance Study (MI CReSS), a population-based survey of Michigan adults with a PCR-confirmed positive SARS-CoV-2 test. The sample was restricted to employed, in-person respondents with COVID-19 onset on or before November 15, 2020 (n = 893). Access to adequate PPE at work was categorized as often/always, sometimes, or rarely/never. Self-reported symptom severity was dichotomized as severe (severe or very severe) or not severe (mild, moderate, or asymptomatic). We used modified Poisson regression to estimate prevalence ratios for the relationship between adequate PPE at work and severe COVID-19 symptoms. We examined effect modification of the relationship by occupation by including a multiplicative interaction term for healthcare worker versus other occupations. After adjusting for sociodemographic and clinical covariates, respondents who rarely/never had access to PPE at work had a 24.7 % higher prevalence of self-reported severe COVID-19 symptoms (PR: 1.25, 95 % CI 1.03-1.51, p-value = 0.024) compared to respondents who often/always had access to PPE at work. Healthcare worker status did not modify the association between access to PPE and symptom severity. The findings from this study suggest an added benefit of PPE in reducing prevalence of severe COVID-19 among all in-person workers.

COVID-19 in the workplace: Self-reported source of exposure and availability of personal protective equipment by industry and occupation in Michigan.

OBJECTIVES: Fragmented industry and occupation surveillance data throughout the COVID-19 pandemic has left public health practitioners and organizations with an insufficient understanding of high-risk worker groups and the role of work in SARS-CoV-2 transmission. METHODS: We drew sequential probability samples of noninstitutionalized adults (18+) in the Michigan Disease Surveillance System with COVID-19 onset before November 16, 2020 (N = 237,468). Among the 6000 selected, 1839 completed a survey between June 23, 2020, and April 23, 2021. We compared in-person work status, source of self-reported SARS-CoV-2 exposure, and availability of adequate personal protective equipment (PPE) by industry and occupation using weighted descriptive statistics and Rao-Scott χ2 tests. We identified industries with a disproportionate share of COVID-19 infections by comparing our sample with the total share of employment by industry in Michigan using 2020 data from the US Bureau of Labor Statistics. RESULTS: Employed respondents (n = 1244) were predominantly female (53.1%), aged 44 and under (54.4%), and non-Hispanic White (64.0%). 30.4% of all employed respondents reported work as the source of their SARS-CoV-2 exposure and 78.8% were in-person workers. Work-related exposure was prevalent in Nursing and Residential Care Facilities (65.2%); Justice, Public Order, and Safety Activities (63.3%); and Food Manufacturing (57.5%). By occupation, work-related exposure was highest among Protective Services (57.9%), Healthcare Support (56.5%), and Healthcare Practitioners (51.9%). Food Manufacturing; Nursing and Residential Care; and Justice, Public Order, and Safety Activities were most likely to report having adequate PPE "never" or "rarely" (36.4%, 27.9%, and 26.7%, respectively). CONCLUSIONS: Workplaces were a key source of self-reported SARS-CoV-2 exposure among employed Michigan residents during the first year of the pandemic. To prevent transmission, there is an urgent need in public health surveillance for the collection of industry and occupation data of people infected with COVID-19, as well as for future airborne infectious diseases for which we have little understanding of risk factors.

Population-Based Estimates of Post-acute Sequelae of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Infection (PASC) Prevalence and Characteristics.

BACKGROUND: Emerging evidence suggests many people have persistent symptoms after acute coronavirus disease 2019 (COVID-19) illness. Our objective was to estimate the prevalence and correlates of post-acute sequelae of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (PASC). METHODS: We used a population-based probability survey of adults with COVID-19 in Michigan. Living noninstitutionalized adults aged ≥18 in the Michigan Disease Surveillance System with COVID-19 onset through mid-April 2020 were eligible for selection (N = 28 000). Among 2000 selected, 629 completed the survey between June-December 2020. We estimated PASC prevalence, defined as persistent symptoms ≥30 (30-day COVID-19) or ≥60 (60-day COVID-19) days post-COVID-19 onset, overall and by sociodemographic and clinical factors. We used modified Poisson regression to produce adjusted prevalence ratios (aPRs) for potential risk factors. RESULTS: The analytic sample (n = 593) was predominantly female (56.1%), aged ≥45 years (68.2%), and non-Hispanic White (46.3%) or Black (34.8%). Thirty- and 60-day COVID-19 were highly prevalent (52.5% and 35.0%), even among nonhospitalized respondents (43.7% and 26.9%) and respondents reporting mild symptoms (29.2% and 24.5%). Respondents reporting very severe (vs mild) symptoms had 2.25 times higher prevalence of 30-day COVID-19 (aPR, 2.25; 95% CI, 1.46-3.46) and 1.71 times higher prevalence of 60-day COVID-19 (aPR, 1.71; 95% CI: 1.02-2.88). Hospitalized (vs nonhospitalized) respondents had ~40% higher prevalence of both 30-day (aPR, 1.37; 95% CI: 1.12-1.69) and 60-day (aPR, 1.40; 95% CI: 1.02-1.93) COVID-19. CONCLUSIONS: PASC is highly prevalent among cases reporting severe initial symptoms and, to a lesser extent, cases reporting mild and moderate symptoms.

Quantifying the excess risk of infant mortality based on race/ethnicity at the county level to inform Michigan's home visiting outreach plans.

OBJECTIVE: Michigan's infant mortality rate is consistently higher than the national rate, with persistent and significant racial/ethnic disparities. In Michigan, nine counties account for more than 80% of all infant deaths. A home visiting program serving low-income, first-time mothers in high-risk communities is one strategy to reduce infant mortality. The objective of this study was to quantify the risk of infant mortality based on race/ethnicity within Michigan's highest-risk counties to guide outreach for home visiting services in these counties. METHODS: To maximize the efficiency of limited resources and to identify women at highest risk, we used decomposition to develop risk-based, county-specific estimates of excess infant deaths in nine Michigan counties using data from the 2007 to 2009 Michigan resident infant death file linked to the live birth/file. RESULTS: The sample size for these counties was 200,610 live births and 1,836 infant deaths and for the reference population it was 195,180 live births and 1,133 infant deaths The study found that excess mortality varies among populations at the county level when compared to the reference population of infants born to Michigan mothers who attained more than a high school education and were at least 20 years of age at the infant's birth. The excess risk of mortality was highest for African American infants in seven of the nine counties (56.5% to 132.8%) and for Hispanic infants (86.6%) and white infants (48.2%) in one county each. CONCLUSION: Even with a longstanding commitment and legal mandate to reduce disparities and with efforts to improve outreach into high-risk areas, disparities persist. An improved understanding of the racial/ethnic disparities within communities was useful to focus outreach efforts on reaching women at highest risk as part of subsequent program enrollment.

Assisted reproduction and risk of preterm birth in singletons by infertility diagnoses and treatment modalities: a population-based study.

PURPOSE: The purpose of this study is to examine the spectrum of infertility diagnoses and assisted reproductive technology (ART) treatments in relation to risk of preterm birth (PTB) in singletons. METHODS: Population-based assisted reproductive technology surveillance data for 2000-2010 were linked with birth certificates from three states: Florida, Massachusetts, and Michigan, resulting in a sample of 4,370,361 non-ART and 28,430 ART-related singletons. Logistic regression models with robust variance estimators were used to compare PTB risk among singletons conceived with and without ART, the former grouped by parental infertility diagnoses and treatment modalities. Demographic and pregnancy factors were included in adjusted analyses. RESULTS: ART was associated with increased PTB risk across all infertility diagnosis groups and treatment types: for conventional ART, adjusted relative risks ranged from 1.4 (95% CI 1.0, 1.9) for male infertility to 2.4 (95% CI 1.8, 3.3) for tubal ligation. Adding intra-cytoplasmic sperm injection and/or assisted hatching to conventional ART treatment did not alter associated PTB risks. Singletons conceived by mothers without infertility diagnosis and with donor semen had an increased PTB risk relative to non-ART singletons. CONCLUSIONS: PTB risk among ART singletons is increased within each treatment type and all underlying infertility diagnosis, including male infertility. Preterm birth in ART singletons may be attributed to parental infertility, ART treatments, or their combination.

Maternal Racial and Ethnic Disparities in Neonatal Birth Outcomes With and Without Assisted Reproduction.

OBJECTIVE: To explore disparities in prematurity and low birth weight (LBW) by maternal race and ethnicity among singletons conceived with and without assisted reproductive technology (ART). METHODS: We performed a retrospective cohort study using resident birth certificate data from Florida, Massachusetts, and Michigan linked with data from the National ART Surveillance System from 2000 to 2010. There were 4,568,822 live births, of which 64,834 were conceived with ART. We compared maternal and ART cycle characteristics of singleton liveborn neonates using χ tests across maternal race and ethnicity groups. We used log binomial models to explore associations between maternal race and ethnicity and LBW and preterm birth by ART conception status. RESULTS: The proportion of liveborn neonates conceived with ART differed by maternal race and ethnicity (P<.01). It was smallest among neonates of non-Hispanic black (0.3%) and Hispanic women (0.6%) as compared with neonates of non-Hispanic white (2.0%) and Asian or Pacific Islander women (1.9%). The percentages of LBW or preterm singletons were highest for neonates of non-Hispanic black women both for non-ART (11.3% and 12.4%) and ART (16.1% and 19.1%) -conceived neonates. After adjusting for maternal factors, the risks of LBW or preterm birth for singletons born to non-Hispanic black mothers were 2.12 [95% confidence interval (CI) 2.10-2.14] and 1.56 (95% CI 1.54-1.57) times higher for non-ART neonates and 1.87 (95% CI 1.57-2.23) and 1.56 (95% CI 1.34-1.83) times higher for ART neonates compared with neonates of non-Hispanic white women. The adjusted risk for LBW was also significantly higher for ART and non-ART singletons born to Hispanic (adjusted relative risk [RR] 1.26, 95% CI 1.09-1.47 and adjusted RR 1.15, 95% CI 1.13-1.16) and Asian or Pacific Islander (adjusted RR 1.39, 95% CI 1.16-1.65 and adjusted RR 1.55, 95% CI 1.52-1.58) women compared with non-Hispanic white women. CONCLUSION: Disparities in adverse perinatal outcomes by maternal race and ethnicity persisted for neonates conceived with and without ART.

Perinatal outcomes among singletons after assisted reproductive technology with single-embryo or double-embryo transfer versus no assisted reproductive technology.

OBJECTIVE: To examine outcomes of singleton pregnancies conceived without assisted reproductive technology (non-ART) compared with singletons conceived with ART by elective single-embryo transfer (eSET), nonelective single-embryo transfer (non-eSET), and double-embryo transfer with the establishment of 1 (DET -1) or ≥2 (DET ≥2) early fetal heartbeats. DESIGN: Retrospective cohort using linked ART surveillance data and vital records from Florida, Massachusetts, Michigan, and Connecticut. SETTING: Not applicable. PATIENT(S): Singleton live-born infants. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Preterm birth (PTB <37 weeks), very preterm birth (VPTB <32 weeks), small for gestational age birth weight (<10th percentile), low birth weight (LBW <2,500 g), very low birth weight (VLBW <1,500 g), 5-minute Apgar score <7, and neonatal intensive care unit (NICU) admission. RESULT(S): After controlling for maternal characteristics and employing a weighted propensity score approach, we found that singletons conceived after eSET were less likely to have a 5-minute Apgar <7 (adjusted odds ratio [aOR] 0.33; 95% CI, 0.15-0.69) compared with non-ART singletons. There were no differences among outcomes between non-ART and non-eSET infants. We found that PTB, VPTB, LBW, and VLBW were more likely among DET -1 and DET ≥2 compared with non-ART infants, with the odds being higher for DET ≥2 (PTB aOR 1.58; 95% CI, 1.09-2.29; VPTB aOR 2.46; 95% CI, 1.20-5.04; LBW aOR 2.17; 95% CI, 1.24-3.79; VLBW aOR 3.67; 95% CI, 1.38-9.77). CONCLUSION(S): Compared with non-ART singletons, singletons born after eSET and non-eSET did not have increased risks whereas DET -1 and DET ≥2 singletons were more likely to have adverse perinatal outcomes.

Assisted Reproductive Technology and Newborn Size in Singletons Resulting from Fresh and Cryopreserved Embryos Transfer.

OBJECTIVES AND STUDY DESIGN: The aim of this study was two-fold: to investigate the association of Assisted Reproductive Technology (ART) and small newborn size, using standardized measures; and to examine within strata of fresh and cryopreserved embryos transfer, whether this association is influenced by parental infertility diagnoses. We used a population-based retrospective cohort from Michigan (2000-2009), Florida and Massachusetts (2000-2010). Our sample included 28,946 ART singletons conceived with non-donor oocytes and 4,263,846 non-ART singletons. METHODS: Regression models were used to examine the association of ART and newborn size, measured as small for gestational age (SGA) and birth-weight-z-score, among four mutually exclusive infertility groups: female infertility only, male infertility only, combined female and male infertility, and unexplained infertility, stratified by fresh and cryopreserved embryos transfer. RESULTS: We found increased SGA odds among ART singletons from fresh embryos transfer compared with non-ART singletons, with little difference by infertility source [adjusted odds-ratio for SGA among female infertility only: 1.18 (95% CI 1.10, 1.26), male infertility only: 1.20 (95% CI 1.10, 1.32), male and female infertility: 1.18 (95% CI 1.06, 1.31) and unexplained infertility: 1.24 (95% CI 1.10, 1.38)]. Conversely, ART singletons, born following cryopreserved embryos transfer, had lower SGA odds compared with non-ART singletons, with mild variation by infertility source [adjusted odds-ratio for SGA among female infertility only: 0.56 (95% CI 0.45, 0.71), male infertility only: 0.64 (95% CI 0.47, 0.86), male and female infertility: 0.52 (95% CI 0.36, 0.77) and unexplained infertility: 0.71 (95% CI 0.47, 1.06)]. Birth-weight-z-score was significantly lower for ART singletons born following fresh embryos transfer than non-ART singletons, regardless of infertility diagnoses.

Using multiple imputation to address the inconsistent distribution of a controlling variable when modeling an infrequent outcome.

Temporal changes in methods for collecting longitudinal data can generate inconsistent distributions of affected variables, but effects on parameter estimates have not been well described. We examined differences in Apgar scores of infants born in 2000-2006 to women with ovulatory dysfunction (risk) or tubal obstruction (reference) who underwent assisted reproductive technology (ART), using Florida, Massachusetts, and Michigan birth certificate data linked to the Centers for Disease Control and Prevention's National ART Surveillance System database. Florida had inconsistent information on induction of labor (a control variable) from a 2004 change in birth certificate format. Because we wanted to control for bias that may be introduced by the inconsistent distribution of labor induction in analysis, we used multiple imputation data in analysis. We used Cox-Iannacchione weighted sequential hot deck method to conduct multiple imputation for the labor induction values in Florida data collected before this change, and missing values in Florida data collected after the change and overall Massachusetts and Michigan data. The adjusted odds ratios for low Apgar score were 1.94 (95% confidence interval [CI] 1.32-2.85) using imputed induction of labor and 1.83 (95% CI 1.20-2.80) using not imputed induction of labor. Compared with the estimate from multiple imputation, the estimate obtained using not imputed induction of labor was biased towards the null with inflated standard errors, but the magnitude of differences was small.

Assisted reproductive technology and perinatal outcomes: conventional versus discordant-sibling design.

OBJECTIVE: To compare risks of adverse perinatal outcomes between assisted reproductive technology (ART) and naturally conceived singleton births using a dual design approach. DESIGN: Discordant-sibling and conventional cross-sectional general population comparison. SETTING: Not applicable. PATIENT(S): All singleton live births, conceived naturally or via ART. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Birth weight, gestational age, low birth weight, preterm delivery, small for gestational age (SGA), low Apgar score. RESULT(S): A total of 32,762 (0.8%) of 3,896,242 singleton live births in the three states were conceived via ART. In 6,458 sibling pairs, ART-conceived singletons were 33 g lighter (adjusted ß = -33.40, 95% confidence interval [CI], -48.60, -18.21) and born half a day sooner (ß = -0.58, 95% CI, -1.02, -0.14) than singletons conceived naturally. The absolute risk of low birth weight and preterm birth was 6.8% and 9.7%, respectively, in the ART group and 4.9% and 7.9%, respectively, in the non-ART group. The odds of low birth weight were 33% higher (adjusted odds ratio [aOR] = 1.33; 95% CI, 1.13, 1.56) and 20% higher for preterm birth (aOR = 1.20; 95% CI, 1.07, 1.34). The odds of SGA and low Apgar score were not significantly different in both groups (aOR = 1.22; 95% CI, 0.88, 1.68; and aOR = 0.75; 95% CI, 0.54, 1.05, respectively). Results of conventional analyses were similar, although the magnitude of risk was higher for preterm birth (aOR, 1.51; 95% CI 1.46, 1.56). CONCLUSION(S): Despite some inflated risks in the general population comparison, ART remained associated with an increased likelihood of low birth weight and preterm birth when underlying maternal factors were kept constant using discordant-sibling comparison.

Antenatal Hospitalizations Among Pregnancies Conceived With and Without Assisted Reproductive Technology.

OBJECTIVE: To describe the prevalence of antenatal hospitalizations, compare characteristics of women with and without antenatal hospitalizations, and compare timing, length of stay, and reason for hospitalization among pregnancies conceived with and without assisted reproductive technology (ART). METHODS: We performed a retrospective cohort analysis using linked ART surveillance, vital records, and hospital discharge data from Michigan to calculate the hospitalization ratio as the number of antenatal admissions per 100 live birth deliveries for ART and non-ART deliveries during 2004-2012 and compare trends by ART status. We then restricted analysis to 2008-2012 and used logistic, multinomial, and Poisson regression analysis to model antenatal admissions, trimester of admission, and length of stay, respectively, for ART compared with non-ART deliveries. We examined reason for hospitalization by ART status. RESULTS: Between 2004 and 2012, the hospitalization ratio for ART deliveries decreased from 14.6 to 12.3 per 100 deliveries (P<.001). Of 557,708 live deliveries during 2008-2012, 22,763 (4.1%) had an antenatal hospitalization. Assisted reproductive technology was a risk factor for having any antenatal admission (singletons adjusted risk ratio [RR] 1.63, 95% confidence interval [CI] 1.43-1.83; multiples adjusted RR 1.24, 95% CI 1.12-1.38) and two or more admissions (singletons adjusted RR 1.86, 95% CI 1.25-2.75; multiples adjusted RR 1.33, 95% CI 1.14-1.54). The percent of time (days) hospitalized during the antenatal period was greater for ART deliveries than non-ART deliveries (singleton adjusted RR 1.28, 95% CI 1.09-1.51; multiples adjusted RR 1.14, 95% CI 1.01-1.29). The most common reason for antenatal admission was preterm labor among all non-ART and multiple gestation deliveries and vaginal bleeding among ART singleton gestations. CONCLUSION: Deliveries after ART were associated with increased risk of antenatal admissions and longer hospitalizations compared with non-ART deliveries.

The Impact of ART on Live Birth Outcomes: Differing Experiences across Three States.

BACKGROUND: Research has shown an association between assisted reproductive technology (ART) and adverse birth outcomes. We identified whether birth outcomes of ART-conceived pregnancies vary across states with different maternal characteristics, insurance coverage for ART services, and type of ART services provided. METHODS: CDC's National ART Surveillance System data were linked to Massachusetts, Florida, and Michigan vital records from 2000 through 2006. Maternal characteristics in ART- and non-ART-conceived live births were compared between states using chi-square tests. We performed multivariable logistic regression analyses and calculated adjusted odds ratios (aOR) to assess associations between ART use and singleton preterm delivery (<32 weeks, <37 weeks), singleton small for gestational age (SGA) (<5th and <10th percentiles) and multiple birth. RESULTS: ART use in Massachusetts was associated with significantly lower odds of twins as well as triplets and higher order births compared to Florida and Michigan (aOR 22.6 vs. 30.0 and 26.3, and aOR 37.6 vs. 92.8 and 99.2, respectively; Pinteraction < 0.001). ART use was associated with increased odds of SGA in Michigan only, and with preterm delivery (<32 and <37 weeks) in all states (aOR range: 1.60, 1.87). CONCLUSIONS: ART use was associated with an increased risk of preterm delivery among singletons that showed little variability between states. The number of twins, triplets and higher order gestations per cycle was lower in Massachusetts, which may be due to the availability of insurance coverage for ART in Massachusetts.

From Theory to Measurement: Recommended State MCH Life Course Indicators.

PURPOSE: In May 2012, the Association of Maternal and Child Health (MCH) Programs initiated a project to develop indicators for use at a state or community level to assess, monitor, and evaluate the application of life course principles to public health. DESCRIPTION: Using a developmental framework established by a national expert panel, teams of program leaders, epidemiologists, and academicians from seven states proposed indicators for initial consideration. More than 400 indicators were initially proposed, 102 were selected for full assessment and review, and 59 were selected for final recommendation as Maternal and Child Health (MCH) life course indicators. ASSESSMENT: Each indicator was assessed on five core features of a life course approach: equity, resource realignment, impact, intergenerational wellness, and life course evidence. Indicators were also assessed on three data criteria: quality, availability, and simplicity. CONCLUSION: These indicators represent a major step toward the translation of the life course perspective from theory to application. MCH programs implementing program and policy changes guided by the life course framework can use these initial measures to assess and influence their approaches.

Embryo transfer practices and perinatal outcomes by insurance mandate status.

OBJECTIVE: To use linked assisted reproductive technology (ART) surveillance and birth certificate data to compare ET practices and perinatal outcomes for a state with a comprehensive mandate requiring coverage of IVF services versus states without a mandate. DESIGN: Retrospective cohort study. SETTING: Not applicable. PATIENT(S): Live-birth deliveries ascertained from linked 2007-2009 National ART Surveillance System and birth certificate data for a state with an insurance mandate (Massachusetts) and two states without a mandate (Florida and Michigan). INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Number of embryos transferred, multiple births, low birth weight, preterm delivery. RESULT(S): Of the 230,038 deliveries in the mandate state and 1,026,804 deliveries in the nonmandate states, 6,651 (2.9%) and 8,417 (0.8%), respectively, were conceived by ART. Transfer of three or more embryos was more common in nonmandate states, although the effect was attenuated for women 35 years or older (33.6% vs. 39.7%; adjusted relative risk [RR], 1.46; 95% confidence interval [CI], 1.17-1.81) versus women younger than 35 (7.0% vs. 26.9%; adjusted RR, 4.18; 95% CI, 2.74-6.36). Lack of an insurance mandate was positively associated with triplet/higher order deliveries (1.0% vs. 2.3%; adjusted RR, 2.44; 95% CI, 1.81-3.28), preterm delivery (22.6% vs. 30.7%; adjusted RR, 1.31; 95% CI, 1.20-1.42), and low birth weight (22.3% vs. 29.5%; adjusted RR, 1.28; 95% CI, 1.17-1.40). CONCLUSION(S): Compared with nonmandate states, the mandate state had higher overall rates of ART use. Among ART births, lack of an infertility insurance mandate was associated with increased risk for adverse perinatal outcomes.

Assisted reproductive technology and the risk of preterm birth among primiparas.

OBJECTIVE: To investigate the risk of preterm birth among liveborn singletons to primiparas who conceived with assisted reproductive technology (ART) using four mutually exclusive categories of infertility (female infertility only, male infertility only, female and male infertility, and unexplained infertility) and to examine preterm birth risk along the gestational age continuum. DESIGN: Retrospective cohort study. SETTING: Not applicable. PATIENT(S): Singletons born to primiparas who conceived with or without ART. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Preterm (<37 weeks' gestation) and preterm/early term birth <39 weeks' gestation). RESULT(S): For the male infertility only, female infertility only, combined male and female infertility, and unexplained infertility groups, ART-conceived singletons were significantly more likely than non-ART singletons to be born preterm: adjusted odds ratio (aOR) 1.24 (95% CI, 1.13, 1.37), aOR 1.60 (95% CI, 1.50, 1.70), aOR 1.49 (95% CI, 1.35, 1.64), and aOR 1.26 (1.12, 1.43) respectively. Among infants whose mothers were diagnosed with infertility, the odds of preterm birth were highest between 28-30 weeks [female infertility only, aOR 1.95 (95% CI, 1.59, 2.39); male and female infertility: 2.21 (95% CI, 1.62, 3.00)] compared with infants in the general population. Within the ART population, singletons of couples with female infertility only were more likely to be born preterm than singletons born to couples with other infertility diagnoses. CONCLUSION(S): Among singleton births to primiparas, those conceived with ART had an increased risk for preterm birth, even when only the male partner had been diagnosed with infertility. The risk of preterm birth for ART-conceived infants whose mothers were diagnosed with infertility included the earliest deliveries.

Maternal characteristics and pregnancy outcomes after assisted reproductive technology by infertility diagnosis: ovulatory dysfunction versus tubal obstruction.

OBJECTIVE: To examine differences in maternal characteristics and pregnancy outcomes between women with ovulatory dysfunction (OD) and women with tubal obstruction (TO) who underwent assisted reproductive technology (ART). DESIGN: Retrospective cohort study. SETTING: Centers for Disease Control and Prevention. PATIENT(S): Exposed and nonexposed groups were selected from the 2000-2006 National ART Surveillance System linked with live-birth certificates from three states: Florida, Massachusetts, and Michigan. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Maternal characteristics and pregnancy outcomes, including newborn's health status right after delivery (Apgar score, <7 vs. ≥ 7) as the study outcome of interest, were assessed among women with OD/polycystic ovary syndrome (PCOS) and TO who used ART. RESULT(S): A significantly higher prevalence of women with OD/PCOS were younger (<35 years of age; 65.7% vs. 48.9%), were white (85.4% vs. 74.4%), had higher education (29.4% vs. 15.6%), and experienced diabetes (8.8% vs. 5.3%) compared with those having TO. The odds of having a lower (<7) Apgar score at 5 minutes were almost twice as high among newborns of women with OD/PCOS compared with those with TO (crude odds ratio, 1.86; 95% confidence interval [CI], 1.31, 2.64; adjusted odds ratio, 1.90; 95% CI, 1.30, 2.77). CONCLUSION(S): Women with OD/PCOS who underwent ART have different characteristics and health issues (higher prevalence of diabetes) and infant outcomes (lower Apgar score) compared with women with TO.

States Monitoring Assisted Reproductive Technology (SMART) Collaborative: data collection, linkage, dissemination, and use.

Assisted reproductive technology (ART) refers to fertility treatments in which both eggs and sperm are handled outside the body. The Centers for Disease Control and Prevention (CDC) oversees the National ART Surveillance System (NASS), which collects data on all ART procedures performed in the United States. The NASS, while a comprehensive source of data on ART patient demographics and clinical procedures, includes limited information on outcomes related to women's and children's health. To examine ART-related health outcomes, CDC and three states (Massachusetts, Florida, and Michigan) established the States Monitoring ART (SMART) Collaborative to evaluate maternal and perinatal outcomes of ART and improve state-based ART surveillance. To date, NASS data have been linked with states' vital records, disease registries, and hospital discharge data with a linkage rate of 90.2%. The probabilistic linkage methodology used in the SMART Collaborative has been validated and found to be both accurate and efficient. A wide breadth of applied research within the Collaborative is planned or ongoing, including examinations of the impact of insurance mandates on ART use as well as the relationships between ART and birth defects and cancer, among others. The SMART Collaborative is working to improve state-based ART surveillance by developing state surveillance plans, establishing partnerships, and conducting data analyses. The SMART Collaborative has been instrumental in creating linked datasets and strengthening epidemiologic and research capacity for improving maternal and infant health programs and evaluating the public health impact of ART.
