Sudden Unexpected Infant Deaths: 2015-2020.

OBJECTIVE: Although the US infant mortality rate reached a record low in 2020, the sudden infant death syndrome (SIDS) rate increased from 2019. To understand if the increase was related to changing death certification practices or the coronavirus disease 2019 (COVID-19) pandemic, we examined sudden unexpected infant death (SUID) rates as a group, by cause, and by race and ethnicity. METHODS: We estimated SUID rates during 2015 to 2020 using US period-linked birth and death data. SUID included SIDS, unknown cause, and accidental suffocation and strangulation in bed. We examined changes in rates from 2019 to 2020 and assessed linear trends during prepandemic (2015-2019) using weighted least squares regression. We also assessed race and ethnicity trends and quantified COVID-19-related SUID. RESULTS: Although the SIDS rate increased significantly from 2019 to 2020 (P < .001), the overall SUID rate did not (P = .24). The increased SIDS rate followed a declining linear trend in SIDS during 2015 to 2019 (P < .001). Other SUID causes did not change significantly. Our race and ethnicity analysis showed SUID rates increased significantly for non-Hispanic Black infants from 2019 to 2020, widening the disparities between these two groups during 2017 to 2019. In 2020, <10 of the 3328 SUID had a COVID-19 code. CONCLUSIONS: Diagnositic shifting likely explained the increased SIDS rate in 2020. Why the SUID rate increased for non-Hispanic Black infants is unknown, but warrants continued monitoring. Interventions are needed to address persistent racial and ethnic disparities in SUID.

Recurrent SARS-CoV-2 RNA Detection after COVID-19 Illness Onset during Pregnancy.

The Surveillance for Emerging Threats to Mothers and Babies Network conducts longitudinal surveillance of pregnant persons in the United States with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 infection during pregnancy. Of 6,551 infected pregnant persons in this analysis, 142 (2.2%) had positive RNA tests >90 days and up to 416 days after infection.

Severe Maternal Morbidity at Delivery and Risk of Hospital Encounters Within 6 Weeks and 1 Year Postpartum.

BACKGROUND: Little is known about the impact of severe maternal morbidity (SMM) after delivery. We examined the risk of rehospitalization in the first year postpartum among deliveries to women with and without SMM. MATERIALS AND METHODS: We used the Pregnancy to Early Life Longitudinal data system, in which vital birth/fetal death records were linked with hospital delivery discharge data and subsequent nondelivery hospitalization data, including observational stays (OSs) and in-patient stays (hospital discharge [HD]) for Massachusetts residents during 2002-2011. We excluded deliveries to women with preexisting chronic conditions: hypertension, diabetes, asthma, and autoimmune conditions for a final sample of 685,228 deliveries. Multivariable log binomial regression with generalized estimating equations modeled the relative risk (RR) of hospital encounters 6 weeks and 1 year postpartum. RESULTS: The rate of SMM was 99 per 10,000 deliveries. In the first year postpartum, 2.8% of deliveries to women without chronic medical conditions experienced at least one HD encounter and 1.0% at least one OS encounter. The adjusted relative risk (aRR) of any HD encounter for deliveries with SMM was 2.48 (95% confidence interval [CI]: 2.20-2.80) within 6 weeks postpartum and 2.04 (95% CI: 1.87-2.23) within 1 year. For OS encounters, aRRs among deliveries with SMM at delivery were 2.47 (95% CI: 1.94-3.14) in the first 6 weeks and 1.69 (95% CI: 1.43-2.01) in 1 year. CONCLUSIONS: In Massachusetts, SMM increased the risk of rehospitalization in the first year postpartum among deliveries to women without chronic medical conditions.

Lessons Learned: Implementation of Pilot Universal Postpartum Nurse Home Visiting Program, Massachusetts 2013-2016.

Purpose Home visiting programs for new families in the United States have traditionally served high-risk families. In contrast, universal home visiting models serve all families regardless of income, age, risk or other criteria. They offer an entry point into a system of care for children and families, with the potential to improve population health. This paper describes lessons learned from the first three years of implementing a universal home visiting model. Description Welcome Family is a universal home visiting program in Massachusetts that offers a one-time visit by a nurse to new mothers up to eight weeks postpartum. The Massachusetts Department of Public Health (MDPH) is piloting Welcome Family in four communities with the goal of expanding statewide. Assessment Welcome Family served over 3000 families in its first three years. Program performance measures provided a framework to examine successes and challenges related to outreach and enrollment, program operations, and linkages with community resources. Early challenges included increasing referrals to a new program and limited capacity to serve all women giving birth. Local implementing agencies tested innovative strategies and MDPH made program modifications, such as developing quarterly data reports and establishing a learning collaborative, to address identified challenges. Conclusion MDPH is committed to the success of Welcome Family and uses continuous quality improvement to maximize the impact of the program on families and the system of care in Massachusetts. Lessons learned from the Massachusetts pilot can inform other states' efforts to enhance their early childhood systems of care through expanding universal home visiting.

Community-Academic Partnership to Investigate Low Birth Weight Deliveries and Improve Maternal and Infant Outcomes at a Baltimore City Hospital.

Purpose Mercy Medical Center (MMC), a community hospital in Baltimore Maryland, has undertaken a community initiative to reduce low birth weight (LBW) deliveries by 10 % in 3 years. MMC partnered with a School of Public Health to evaluate characteristics associated with LBW deliveries and formulate collaborations with obstetricians and community services to improve birth outcomes. Description As part of the initiative, a case control study of LBW was undertaken of all newborns weighing <2500 grams during June 2010-June 2011 matched 2:1 with newborns ≥2500 grams (n = 862). Assessment Logistic regression models including maternal characteristics prior to and during pregnancy showed an increased odds of LBW among women with a previous preterm birth (aOR 2.48; 95 % CI: 1.49-4.13), chronic hypertension (aOR: 2.53; 95 % CI: 1.25-5.10), hospitalization during pregnancy (aOR: 2.27; 95 % CI:1.52-3.40), multiple gestation (aOR:12.33; 95 % CI:5.49-27.73) and gestational hypertension (aOR: 2.81; 95 % CI: 1.79-4.41). Given that both maternal pre-existing conditions and those occurring during pregnancy were found to be associated with LBW, one strategy to address pregnant women at risk of LBW infants is to improve the intake and referral system to better triage women to appropriate services in the community. Meetings were held with community organizations and feedback was operationalized into collaboration strategies which can be jointly implemented. Conclusion Education sessions with providers about the referral system are one ongoing strategy to improve birth outcomes in Baltimore City, as well as provision of timely home visits by nurses to high-risk women.

Early introduction of complementary foods in preterm infants.

OBJECTIVES: The aim of the present study was to determine the odds of early introduction of solid foods in a nationally representative sample of preterm infants when compared with term infants and to examine whether factors associated with early introduction are the same for preterm and term infants. METHODS: Our sample of 7650 came from the first wave of the Early Childhood Longitudinal Study, Birth Cohort (2001-2002). We performed multivariable logistic regression to determine whether preterm infants were introduced to solid foods more frequently before 4 months than term infants using adjusted age for preterm infants and chronological age for term infants. In a separate analysis in preterm infants, we used multivariable logistic regression to determine whether the factors associated with early introduction in term infants were the same in the preterm sample. RESULTS: Infants born 22 to 32 weeks' gestation had a 9.90 (95% confidence interval 5.54-18.0) odds of being fed solid food before 4 months compared with term infants, and infants born 33 to 36 weeks' gestation had a 6.19 (95% confidence interval 4.58-8.36) odds. Race/ethnicity and maternal smoking were the only factors that predicted early solid feeding in both preterm and term infants; the remaining predictors differed. CONCLUSIONS: Preterm infants are significantly more likely to be introduced to complementary foods early compared with term infants. The predictors of early solid feeding differ for preterm infants. Given the health implications, specific guidelines for preterm infants should be developed and future research should examine predictors of early introduction in preterm infants.

Adverse childhood experiences and child health in early adolescence.

IMPORTANCE: Child maltreatment and other adverse childhood experiences, especially when recent and ongoing, affect adolescent health. Efforts to intervene and prevent adverse childhood exposures should begin early in life but continue throughout childhood and adolescence. OBJECTIVES: To examine the relationship between previous adverse childhood experiences and somatic concerns and health problems in early adolescence, as well as the role of the timing of adverse exposures. DESIGN: Prospective analysis of the Longitudinal Studies of Child Abuse and Neglect interview and questionnaire data when target children were 4, 6, 8, 12, and 14 years old. SETTING: Children with reported or at risk for maltreatment in the South, East, Midwest, Northwest, and Southwest United States Longitudinal Studies of Child Abuse and Neglect sites. PARTICIPANTS: A total of 933 children who completed an interview at age 14 years, including health outcomes. EXPOSURES: Eight categories of adversity (psychological maltreatment, physical abuse, sexual abuse, neglect, caregiver's substance use/alcohol abuse, caregiver's depressive symptoms, caregiver treated violently, and criminal behavior in the household) experienced during the first 6 years of life, the second 6 years of life, the most recent 2 years, and overall adversity. MAIN OUTCOMES AND MEASURES: Child health problems including poor health, illness requiring a doctor, somatic concerns, and any health problem at age 14 years. RESULTS: More than 90% of the youth had experienced an adverse childhood event by age 14 years. There was a graded relationship between adverse childhood exposures and any health problem, while 2 and 3 or more adverse exposures were associated with somatic concerns. Recent adversity appeared to uniquely predict poor health, somatic concerns, and any health problem. CONCLUSIONS AND RELEVANCE: Childhood adversities, particularly recent adversities, already show an impact on health outcomes by early adolescence. Increased efforts to prevent and mitigate these experiences may improve the health outcome for adolescents and adults.

Weight and mental health status in Massachusetts, National Survey of Children's Health, 2007.

This study explores how weight status is related to mental health status among Massachusetts children, aged 10-17 years. We used data from the 2007 National Survey of Children's Health to examine the association between weight status (body mass index-for-age) and parent-reported mental health status among Massachusetts children (N = 827). Multivariable log binomial regression was performed to calculate the adjusted prevalence ratios (aPR) of three mental health outcomes (behavioral, emotional, and social) as related to weight status, after controlling for covariates including physical activity, sex, race/ethnicity, maternal education, poverty status, special health needs, and neighborhood safety. Almost one-third (32.5 %) of Massachusetts children were either overweight or obese. Sex was a significant effect modifier of the association between weight status and negative emotions. After stratifying by sex and controlling for covariates, the relationship between weight status and negative emotions remained significant among girls (aPR = 1.8, 95 % CI 1.3-2.6). Children who did not exercise at all were significantly more likely to exhibit negative behaviors (aPR = 1.3, 95 % CI 1.0-1.6), negative emotions (boys' aPR = 3.3, 95 % CI 1.6-6.9; girls' aPR = 2.6, 95 % CI 1.5-4.5), and fewer social skills (aPR = 1.9, 95 % CI 1.3-2.9) than those who exercised at least 20 min every day of the week. Overweight/obese children, especially girls, were more likely than children of normal weight to have parent-reported negative emotions, suggesting an association between weight status and mental health. Lower levels of physical activity were associated with negative mental health outcomes, supporting the benefits of physical activity for all children.
