RESUMO
PURPOSE: It is unclear whether common maternal infections during pregnancy are risk factors for adverse birth outcomes. We assessed the association between self-reported infections during pregnancy with preterm birth and small-for-gestational-age (SGA) in an international cohort consortium. METHODS: Data on 120,507 pregnant women were obtained from six population-based birth cohorts in Australia, Denmark, Israel, Norway, the UK and the USA. Self-reported common infections during pregnancy included influenza-like illness, common cold, any respiratory tract infection, vaginal thrush, vaginal infections, cystitis, urinary tract infection, and the symptoms fever and diarrhoea. Birth outcomes included preterm birth, low birth weight and SGA. Associations between maternal infections and birth outcomes were first assessed using Poisson regression in each cohort and then pooled using random-effect meta-analysis. Risk ratios (RR) and 95% confidence intervals (CI) were calculated, adjusted for potential confounders. RESULTS: Vaginal infections (pooled RR, 1.10; 95% CI, 1.02-1.20) and urinary tract infections (pooled RR, 1.17; 95% CI, 1.09-1.26) during pregnancy were associated with higher risk of preterm birth. Similar associations with low birth weight were also observed for these two infections. Fever during pregnancy was associated with higher risk of SGA (pooled RR, 1.07; 95% CI, 1.02-1.12). No other significant associations were observed between maternal infections/symptoms and birth outcomes. CONCLUSION: Vaginal infections and urinary infections during pregnancy were associated with a small increased risk of preterm birth and low birth weight, whereas fever was associated with SGA. These findings require confirmation in future studies with laboratory-confirmed infection diagnosis.

Prenatal stress has a significant, but small, negative effect on children's executive function (EF) in middle and high socioeconomic status (SES) households. Importantly, rates and severity of prenatal stress are higher and protective factors are reduced in lower SES households, suggesting prenatal stress may be particularly detrimental for children's EF in this population. This study examined whether prenatal stress was linked to 5-year-old's EF in a predominantly low SES sample and child sex moderated this association, as males may be more vulnerable to adverse prenatal experiences. Participants were 132 mother-child dyads drawn from a prospective prenatal cohort. Mothers reported on their depression symptoms, trait anxiety, perceived stress, everyday discrimination, and sleep quality at enrollment and once each trimester, to form a composite prenatal stress measure. Children's EF was assessed at age 5 years using the parent-report Behavior Rating Inventory of Executive Function - Preschool (BRIEF-P) Global Executive Composite subscale and neuropsychological tasks completed by the children. Mixed models revealed higher prenatal stress was associated with lower BRIEF-P scores, indicating better EF, for females only. Higher prenatal stress was associated with lower performance on neuropsychological EF measures for both males and females. Results add to the limited evidence about prenatal stress effects on children's EF in low SES households.
RESUMO
BACKGROUND: Off-label treatment of extremely preterm infants with diuretics and inhaled corticosteroids (ICS) for evolving bronchopulmonary dysplasia (BPD) is common. Their effectiveness in reducing mortality or BPD severity, and optimal treatment timing, are unclear. OBJECTIVES: To determine whether diuretic treatment or ICS administration for infants with early evolving (between 10-27 days postnatal) and progressively evolving (28th-day-36th-week postnatal) BPD are independently associated with reduced mortality and moderate or severe BPD at 36-weeks postmenstrual age (PMA). METHODS: We examined neonates born before 28 weeks' gestation and admitted to neonatal intensive care units on postnatal Day 0 between 2006 and 2016 using data collected during routine care recorded within the Paediatric Health Information System (PHIS). An early evolving BPD cohort consisted of infants treated with oxygen, positive pressure or mechanical ventilation at 10 days postnatal. The progressively evolving BPD cohort consisted of infants treated with these modalities at 28 days. In new users, we evaluated the effect of diuretic and ICS treatment on mortality or BPD severity at 36 weeks PMA, adjusting for time-dependent confounding by respiratory status using marginal structural models. RESULTS: Early evolving BPD was present in 10,135 patients; progressively evolving BPD in 11,728. New diuretic exposure during early evolving BPD (adjusted risk ratio [aRR] 0.77, 95% confidence interval [CI] 0.65, 0.93) was associated with decreased mortality or moderate/severe BPD risk. New diuretics (aRR 0.86, 95% CI 0.75, 0.99) during progressively evolving BPD between 28-days-36-weeks PMA were less strongly associated with mortality or moderate/severe BPD reduction. There was no strong association for ICS in patients with early evolving (aRR: 1.40; 95% CI: 0.79, 2.51) or progressively evolving BPD (aRR 1.16, 95% CI 0.95, 1.49). CONCLUSION: Diuretics, but not ICS, for evolving BPD were associated with mortality and BPD risk reduction.

BACKGROUND: Severe maternal morbidity is increasing in the United States. Black women experience the highest rates of severe maternal morbidity and also of preterm births, which are associated with severe maternal morbidity. The racial disparity of severe maternal morbidity across weeks of gestation has not been well-studied. OBJECTIVE: This study aimed to evaluate differences in severe maternal morbidity between Black and White birthing people by week of gestation. Differences may indicate periods of pregnancy when Black women are particularly vulnerable to severe maternal morbidity and may require additional interventions. STUDY DESIGN: This was a cross-sectional study using the National Inpatient Sample from 2019. We used International Classification of Diseases codes from Centers for Disease Control and Prevention guidelines to identify severe maternal morbidity from delivery hospitalizations. We examined the rates of severe maternal morbidity in Black vs White women by week of gestation to evaluate periods of pregnancy when Black women experience additional risks of severe maternal morbidity while adjusting for age, region, medical comorbidities, and Medicaid enrollment. Severe maternal morbidity was analyzed while both including and excluding cases for which blood transfusion was the only indicator of severe maternal morbidity. RESULTS: Overall, Black birthing people had twice the rate of severe maternal morbidity births compared with White birthing people (2.7% vs 1.3%; P<.0001) and were more likely to deliver preterm (14.7% vs 9.4%; P<.0001). The racial disparity of severe maternal morbidity was present throughout all weeks of gestation, with the largest gap observed at extremely and moderately preterm gestations (22-33 weeks). Rates of severe maternal morbidity for Black women peaked at 22 to 33 weeks' gestation and were lowest at term (≥37 weeks). Black women had a greater proportion of severe maternal morbidity cases due to blood transfusion (68.3% vs 64.5%; P<.01) and acute renal failure (11.1% vs 8.5%; P<.001). CONCLUSION: Black women experience a substantially higher rate of severe maternal morbidity at preterm gestations (22-36 weeks) in addition to higher rates of preterm delivery. Even when accounting for age, medical comorbidities, and social determinants, Black birthing people have higher odds of severe maternal morbidity throughout pregnancy.
RESUMO
BACKGROUND: Up to 26% of urogenital Chlamydia trachomatis infections spontaneously resolve between detection and treatment. Mechanisms governing natural resolution are unknown. We examined whether bacterial vaginosis (BV) was associated with greater chlamydia persistence versus spontaneous clearance in a large, longitudinal study. METHODS: Between 1999 and 2003, the Longitudinal Study of Vaginal Flora followed reproductive-age women quarterly for 1 year. Baseline chlamydia screening and treatment were initiated after ligase chain reaction testing became available midstudy, and unscreened endocervical samples were tested after study completion. Chlamydia clearance and persistence were defined between consecutive visits without chlamydia-active antibiotics (n = 320 persistence/n = 310 clearance). Associations between Nugent score (0-3, no BV; 4-10, intermediate/BV), Amsel-BV, and chlamydia persistence versus clearance were modeled with alternating and conditional logistic regression. RESULTS: Of chlamydia cases, 48% spontaneously cleared by the next visit (310/630). Nugent-intermediate/BV was associated with higher odds of chlamydia persistence (adjusted odds ratio [aOR] = 1.89; 95% confidence interval [CI], 1.30-2.74), and the findings were similar for Amsel-BV (aOR 1.39; 95% CI, .99-1.96). The association between Nugent-intermediate/BV and chlamydia persistence was stronger in a within-participant analysis of 67 participants with both clearance/persistence intervals (aOR = 4.77; 95% CI, 1.39-16.35). BV symptoms did not affect any results. CONCLUSIONS: BV is associated with greater chlamydia persistence. Optimizing the vaginal microbiome may promote chlamydia clearance.

OBJECTIVE: We estimated the association between diabetes and shoulder dystocia by infant birth weight subgroups (<4,000, 4,000-4,500, and >4,500 g) in an era of prophylactic cesarean delivery for suspected macrosomia. STUDY DESIGN: A secondary analysis from the National Institute of Child Health and Human Development U.S. Consortium for Safe Labor of deliveries at ≥24 weeks with a nonanomalous, singleton fetus with vertex presentation undergoing a trial of labor. The exposure was either pregestational or gestational diabetes compared with no diabetes. The primary outcome was shoulder dystocia and secondarily, birth trauma with a shoulder dystocia. We calculated adjusted risk ratios (aRRs) with modified Poison's regression between diabetes and shoulder dystocia and the number needed to treat (NNT) to prevent a shoulder dystocia with cesarean delivery. RESULTS: Among 167,589 assessed deliveries (6% with diabetes), pregnant individuals with diabetes had a higher risk of shoulder dystocia at birth weight <4,000 g (aRR: 1.95; 95% confidence interval [CI]: 1.66-2.31) and 4,000 to 4,500 g (aRR: 1.57; 95% CI: 1.24-1.99), albeit not significantly at birth weight >4,500 g (aRR: 1.26; 95% CI: 0.87-1.82) versus those without diabetes. The risk of birth trauma with shoulder dystocia was higher with diabetes (aRR: 2.29; 95% CI: 1.54-3.45). The NNT to prevent a shoulder dystocia with diabetes was 11 and 6 at ≥4,000 and >4,500 g, versus without diabetes, 17 and 8 at ≥4,000 and >4,500 g, respectively. CONCLUSION: Diabetes increased the risk of shoulder dystocia, even at lower birth weight thresholds than at which cesarean delivery is currently offered. Guidelines providing the option of cesarean delivery for suspected macrosomia may have decreased the risk of shoulder dystocia at higher birth weights. KEY POINTS: · >Diabetes increased the risk of shoulder dystocia, even at lower birth weight thresholds than at which cesarean delivery is currently offered.. · Cesarean delivery for suspected macrosomia may have decreased the risk of shoulder dystocia at higher birth weights.. · These findings can inform delivery planning for providers and pregnant individuals with diabetes..

BACKGROUND: Bacterial vaginosis (BV) increases preterm delivery (PTD) risk, but treatment trials showed mixed results in preventing PTD. OBJECTIVES: Determine, using individual participant data (IPD), whether BV treatment during pregnancy reduced PTD or prolonged time-to-delivery. DATA SOURCES: Cochrane Systematic Review (2013), MEDLINE, EMBASE, journal searches, and searches (January 2013-September 2022) ("bacterial vaginosis AND pregnancy") of (i) clinicaltrials.gov; (ii) Cochrane Central Register of Controlled Trials; (iii) World Health Organization International Clinical Trials Registry Platform Portal; and (iv) Web of Science ("bacterial vaginosis"). STUDY SELECTION AND DATA EXTRACTION: Studies randomising asymptomatic pregnant individuals with BV to antibiotics or control, measuring delivery gestation. Extraction was from original data files. Bias risk was assessed using the Cochrane tool. Analysis used "one-step" logistic and Cox random effect models, adjusting gestation at randomisation and PTD history; heterogeneity by I2 . Subgroup analysis tested interactions with treatment. In sensitivity analyses, studies not providing IPD were incorporated by "multiple random-donor hot-deck" imputation, using IPD studies as donors. RESULTS: There were 121 references (96 studies) with 23 eligible trials (11,979 participants); 13 studies (6915 participants) provided IPD; 12 (6115) were incorporated. Results from 9 (4887 participants) not providing IPD were imputed. Odds ratios for PTD for metronidazole and clindamycin versus placebo were 1.00 (95% CI 0.84, 1.17), I2 = 62%, and 0.59 (95% CI 0.42, 0.82), I2 = 0 before; and 0.95 (95% CI 0.81, 1.11), I2 = 59%, and 0.90 (95% CI: 0.72, 1.12), I2 = 0, after imputation. Time-to-delivery did not differ from null with either treatment. Including imputed IPD, there was no evidence that either drug was more effective when administered earlier, or among those with a PTD history. CONCLUSIONS: Clindamycin, but not metronidazole, was beneficial in studies providing IPD, but after imputing data from missing IPD studies, treatment of BV during pregnancy did not reduce PTD, nor prolong pregnancy, in any subgroup or when started earlier in gestation.

BACKGROUND: Short interpregnancy interval has been associated with increased risk of preterm delivery; recent studies employing within-sibship designs suggest that this risk may be exaggerated. There are unresolved issues regarding properties of this design. OBJECTIVES: To compare directly the results, for short intervals, of between-person and within-sibship analyses when applied to the same target population. METHODS: Cross-sectional data are from the National Survey of Family Growth, a statistically representative survey of women and men in the USA, 2006-2015. Participants provided a complete pregnancy history including outcome, duration and ending date, enabling calculation of interval. Conventional analysis employed log-linear regression, controlling survey design, early life events, demographic variables, pregnancy intendedness, breastfeeding of the previous birth and obstetric history. Within-sibship analyses, utilising conditional log-linear regression, controlled the same variables, except those remaining static within each participant. RESULTS: Among participants with at least three live- or stillbirths, the percentage of pregnancies in each interval, and the percent of deliveries that were preterm following that interval were 9.2%, 14.6% for <6, and 14.7%, 15.4% for 6-11, versus 12.2%, 14.7% for 18-23 months. Among participants with at least three live- or stillborn infants, those in the within-sibship analysis had a higher risk profile than comparably parous, ineligible participants. In a between-participant analysis, among those included in within-sibship models, the adjusted risk ratios (vs 18-23 months) for preterm delivery for intervals <6 and 6-11 months were 0.74 (95% CI 0.63, 0.88) and 0.85 (95% CI 0.74, 0.98). The corresponding risk ratios were 0.56 (95% CI 0.14, 2.30) and 0.49 (95% CI 0.13, 1.80) for those ineligible for the within-sibship models. CONCLUSIONS: When comparable analyses were employed, the association between interval and preterm delivery was similar between participants included in the within-sibship analysis and those ineligible for the within-sibship analysis, but differed from those in the full cohort, perhaps due to different target populations.

A transgenerational, epigenetic effect of anesthesia, particularly fluorinated agents, has been examined in rat models, but translation to humans is unclear. This study examined associations of maternal lifetime exposure to anesthesia and pregnancy exposure to fluorinated anesthetics with child cognitive and educational outcomes. Women in the US Collaborative Perinatal Project (1959-1963) reported lifetime history of surgeries, and the obstetric record captured pregnancy exposure to anesthetics. Children were followed to age 7 for global cognitive ability and educational outcomes (n=47,977). Logistic and linear regressions were adjusted for maternal and child birth years, race and ethnicity, smoking, education, parity, study site. Many outcomes were not associated with exposure to maternal surgery that occurred at various life stages. However, maternal surgery in early childhood was associated both with being in a special school or not in school (adj OR=1.42; 95% CI 1.02, 1.98) and with slightly better cognitive ability across childhood (e.g., WISC IQ (adj ß=0.59; CI 0.13, 1.04) (especially among boys)). Maternal surgery in puberty was associated with slightly lower IQ (adj ß = -0.42; CI -0.79, -0.05) and poorer spelling at age 7. Children's prenatal exposure to fluorinated anesthetics was associated with slightly better spelling ability (adj ß = 1.20; CI 0.02, 2.38) but lower performance IQ at age 7 (only among boys, adj ß = -1.97; CI -3.88, -0.06). This study shows inconsistent evidence of effects of maternal exposure to surgery or prenatal exposure to fluorinated agents on child developmental and educational outcomes Residual confounding by indication and socioeconomic status may explain observed associations.

Throughout the second half of the 20th century, clinicians noted that although African-American neonates were more likely than White neonates to weigh less than 2,500 g at birth (low birth weight), among low-birth-weight infants African Americans were more likely than Whites to survive. However, when born at normal weight, African-American infants were substantially less likely to survive. The observation generated much physiological speculation, and several clever mathematical manipulations were devised to "uncross the mortality curves." With the development and dissemination of directed acyclic graphs in the early 2000s, methodologists focusing on perinatal epidemiology showed graphically, in an early use of directed acyclic graphs, that birth weight was a "collider" and that controlling for birth weight, whether by regression, stratification, or restriction, introduced confounding of the race-mortality association by all unmeasured common causes of birth weight and mortality. These investigations showed that the crossing curves could be explained as an artifact of a conceptually flawed analysis. These results have applicability beyond perinatal epidemiology, including applicability to the "obesity paradox."

OBJECTIVE: The aim of this study was to determine the association of prenatal marijuana exposure with and without tobacco smoke exposure and small for gestational age (SGA) at birth. STUDY DESIGN: We conducted a secondary analysis of the prospective Lifestyle and Early Achievement in Families (LEAF) cohort enrolled from 2010 to 2015. We included singleton nonanomalous liveborn pregnancies. We assessed marijuana use inclusive of any pregnancy urine specimen with a Δ9-THC-COOH concentration of more than 15 ng/mL by mass spectrometry, self-report on questionnaire, and/or electronic health record; and self-reported maternal tobacco use. Because of the high co-frequency of marijuana with tobacco exposure in pregnancy and the known association between tobacco and fetal growth restriction, we modeled the exposure as: both marijuana and tobacco (hereafter "co-use"), only marijuana, only tobacco, and neither (reference). Incidence of SGA in each group was compared with the neither group. The primary outcome was SGA less than 10th percentile, and secondarily less than 5th percentile, using parity-specific definitions per 2017 US natality reference data. RESULTS: Among 325 assessed mothers, 46% had neither exposure, 11% had only prenatal marijuana exposure, 20% only tobacco exposure, and 23% co-use exposure. A third (33%) of infants were SGA less than 10th percentile and 20% SGA less than 5th percentile. Marijuana exposure only was associated with an increased risk of SGA less than 10th percentile (43 vs. 26%; adjusted relative risk [aRR]: 1.66; 95% confidence interval [CI]: 1.02-2.69), and SGA less than5th percentile (30 vs. 13%; aRR: 2.26; 95% CI: 1.15-4.47). Tobacco was not associated with SGA less than 10th percentile, but was with SGA less than 5th percentile (26 vs. 13%; aRR: 2.01; 95% CI: 1.13, 3.56). Co-use was not associated with increased SGA risk in multivariate analysis, but was in sensitivity analysis when tobacco use was defined using a cotinine assay rather than self-report (SGA <10th percentile, aRR: 1.97; 95% CI: 1.24-3.15) and (SGA <5th percentile, aRR: 2.03; 95% CI: 1.09-3.78). CONCLUSION: Prenatal marijuana exposure in addition to tobacco may increase the risk of SGA. Given the rising prevalence of marijuana use in pregnancy, further research is warranted to understand how in utero marijuana exposure may impact fetal growth and birth weight with and without tobacco exposure. KEY POINTS: · Marijuana and tobacco are commonly used together in pregnancy.. · Prenatal marijuana and tobacco exposure may increase the risk of a small for gestational age infant.. · Further research is warranted to understand how in utero marijuana exposure impacts fetal growth..

Importance: Birth in the periviable period between 22 weeks 0 days and 25 weeks 6 days' gestation is a major source of neonatal morbidity and mortality, and the decision to initiate active life-saving treatment is challenging. Objective: To assess whether the frequency of active treatment among live-born neonates in the periviable period has changed over time and whether active treatment differed by gestational age at birth and race and ethnicity. Design, Setting, and Participants: Serial cross-sectional descriptive study using National Center for Health Statistics natality data from 2014 to 2020 for 61â¯908 singleton live births without clinical anomalies between 22 weeks 0 days and 25 weeks 6 days in the US. Exposures: Year of delivery, gestational age at birth, and race and ethnicity of the pregnant individual, stratified as non-Hispanic Asian/Pacific Islander, non-Hispanic Black, Hispanic/Latina, and non-Hispanic White. Main Outcomes and Measures: Active treatment, determined by whether there was an attempt to treat the neonate and defined as a composite of surfactant therapy, immediate assisted ventilation at birth, assisted ventilation more than 6 hours in duration, and/or antibiotic therapy. Frequencies, mean annual percent change (APC), and adjusted risk ratios (aRRs) were estimated. Results: Of 26â¯986â¯716 live births, 61â¯908 (0.2%) were periviable live births included in this study: 5% were Asian/Pacific Islander, 37% Black, 24% Hispanic, and 34% White; and 14% were born at 22 weeks, 21% at 23 weeks, 30% at 24 weeks, and 34% at 25 weeks. Fifty-two percent of neonates received active treatment. From 2014 to 2020, the overall frequency (mean APC per year) of active treatment increased significantly (3.9% [95% CI, 3.0% to 4.9%]), as well as among all racial and ethnic subgroups (Asian/Pacific Islander: 3.4% [95% CI, 0.8% to 6.0%]); Black: 4.7% [95% CI, 3.4% to 5.9%]; Hispanic: 4.7% [95% CI, 3.4% to 5.9%]; and White: 3.1% [95% CI, 1.1% to 4.4%]) and among each gestational age range (22 weeks: 14.4% [95% CI, 11.1% to 17.7%] and 25 weeks: 2.9% [95% CI, 1.5% to 4.2%]). Compared with neonates born to White individuals (57.0%), neonates born to Asian/Pacific Islander (46.2%; risk difference [RD], -10.81 [95% CI, -12.75 to -8.88]; aRR, 0.82 [95% CI, [0.79-0.86]), Black (51.6%; RD, -5.42 [95% CI, -6.36 to -4.50]; aRR, 0.90 [95% CI, 0.89 to 0.92]), and Hispanic (48.0%; RD, -9.03 [95% CI, -10.07 to -7.99]; aRR, 0.83 [95% CI, 0.81 to 0.85]) individuals were significantly less likely to receive active treatment. Conclusions and Relevance: From 2014 to 2020 in the US, the frequency of active treatment among neonates born alive between 22 weeks 0 days and 25 weeks 6 days significantly increased, and there were differences in rates of active treatment by race and ethnicity.

BACKGROUND: Children born extremely preterm disproportionately experience sequelae of preterm birth compared to those born at later gestational ages, including higher prevalence of autism spectrum disorder (ASD) and associated behaviors. AIM: Explore effects of combined dietary docosahexaenoic acid, eicosapentaenoic acid, gamma-linolenic acid, and oleic acid (omega 3-6-9) on caregiver-reported behavior and sleep in toddlers born at ≤29 weeks' gestation who were exhibiting symptoms commonly seen with ASD. STUDY DESIGN: 90-day randomized (1:1), double blinded, placebo-controlled trial. SUBJECTS: Thirty-one children aged 18-38 months received omega 3-6-9 (n = 15) or canola oil placebo (n = 16). OUTCOME MEASURES: Mixed effects regression analyses followed intent to treat and explored treatment effects on measures of caregiver-reported behavior (Child Behavior Checklist 1.5-5, Toddler Behavior Assessment Questionnaire - Short Form, Vineland Adaptive Behavior Scales, 2nd Edition) and sleep (Children's Sleep Habits Questionnaire, Brief Infant Sleep Questionnaire). RESULTS: Twenty-nine of 31 (94%; ntx = 13, nplacebo = 16) children randomized had data available for at least one outcome measure, 27 (87%; ntx = 12, nplacebo = 15) had complete outcome data. Children randomized to omega 3-6-9 experienced a medium magnitude benefit of supplementation on anxious and depressed behaviors (ΔDifference = -1.27, d = -0.58, p = 0.049) and internalizing behaviors (ΔDifference = -3.41, d = -0.68, p = 0.05); and a large magnitude benefit on interpersonal relationship adaptive behaviors (ΔDifference = 7.50, d = 0.83, p = 0.01), compared to placebo. No effects were observed on other aspects of behavior or sleep. CONCLUSIONS: Findings provide preliminary support for further exploration of omega 3-6-9 during toddlerhood to improve socioemotional outcomes among children born preterm, especially for those showing early symptoms commonly seen with ASD. Results need to be replicated in a larger sample. TRIAL REGISTRATION: Registered with ClinicalTrials.gov: NCT01683565.

PURPOSE: To understand risk perception about cannabis use during pregnancy. DESIGN: Mixed -Methods. Setting: Focus groups. Participants: Mothers. METHOD: Focus groups were conducted to learn about person's experiences with pregnancy, health-related behaviors, perception of risky behaviors (cannabis use), and receipt of health-related information during pregnancy. Participants completed the Electronic Health Literacy Scale, the Single Item Literacy Screener, and questions about whether topics were discussed during their prenatal care. Data were coded and analyzed iteratively for emerging themes. Descriptive statistics were used to characterize the sample. RESULTS: Twenty-one persons (mean age = 34.4, 57% African American, 38% White, 5% Multi-racial) participated in 4 focus groups. One-third of the participants used cannabis; 24% used alcohol; and 48% used tobacco during pregnancy. Participant's perceptions and use of cannabis during pregnancy were shaped by relief from pregnancy-related symptoms, recommendations from health care providers that cannabis is safe, anecdotal stories from friends and family, fear associated with prescription medications, and preference for "natural" remedies. The context of distrust of providers permeated these themes. The sample displayed poor e-health literacy compared to other adult samples. CONCLUSION: Inter-related factors that influence cannabis use among persons who are pregnant should be considered when establishing trust between patients and providers, creating messages for patients about cannabis use during pregnancy, and when implementing interventions to improve provider-patient communication about health risk behaviors.

BACKGROUND: Evidence on the role of early growth trajectories and later obesity risk is primarily based on privately insured or universally insured samples. OBJECTIVES: We aimed to characterize and determine factors associated with early growth trajectories and estimate associations with overweight/obesity risk in a Medicaid-insured and uninsured cohort. METHODS: Infants seen at a large pediatric academic centre in 2010-2016 were included. Weight and length/height measurements were converted to age and sex-specific BMI z-scores (BMIz) based on the World Health Organization (WHO) Growth Standards. Group-based trajectories were modelled using BMIz created groups. Logistic and log-binomial regression models estimated associations between membership in trajectories and maternal/child factors and overweight or obesity at 36, 48, and 60 months, separately. Analyses were performed between 2019 and 2021. RESULTS: The best-fitting model identified five BMIz trajectories among 30 189 children and 310 113 clinical encounters; two trajectories showed rapid rise in BMIz. Lower maternal education, pre-pregnancy maternal overweight/obese status, and maternal smoking were positively associated with both rapid-rising BMIz trajectories. Children in either of the two rapid-rising trajectories were 3.00 (95% CI: 2.85, 3.25), 2.97 (95% CI: 2.77, 3.18) and 2.76 (95% CI: 2.53, 3.01) times more likely to have overweight or obesity at 36, 48, and 60 months, respectively compared to children in the stable trajectory groups. CONCLUSIONS: Among Medicaid insured and uninsured children, several maternal and child characteristics were associated with early rapid-rise in BMIz. Clinical monitoring of early rapidly rising BMI may be important to address modifiable risk factors for obesity in families from low-income households.

OBJECTIVE: This study aimed to explore demographic and health-related factors that may differentiate women who do and do not disclose their marijuana use during pregnancy. STUDY DESIGN: The current study is a secondary analysis of data from a prospective cohort of pregnant women identified as using marijuana during pregnancy via a variety of assessment tools including self-report, urine screen, and obstetrics record abstraction. The cohort included a convenience sample of women recruited from several antenatal clinics at The Ohio State University Wexner Medical Center (OSUWMC). To be eligible, women needed to be within the first or second trimester of their pregnancy, 16 to 50 years of age, able to communicate in English, and intended to deliver at OSUWMC. Chi-square, independent samples t-tests, and logistic regression analyses were used to explore differences between those who did and did not disclose their use in relation to physical and mental health diagnoses, adverse experiences, use of other substances, and demographics. RESULTS: Women who used marijuana during their pregnancy and had mental/physical health data available comprised the current sample (n = 109). Women who attended college were more likely to disclose their marijuana use compared with women who did not attend college (p < 0.001). Women who experienced homelessness (p < 0.01) or self-reported alcohol use during pregnancy (p < 0.001) were significantly more likely to disclose their marijuana use. CONCLUSION: Findings, suggesting disclosure of other substance use and adverse experiences, such as homelessness, may increase the likelihood that pregnant women will voluntarily disclose their marijuana use to providers. Findings did not reflect racial differences nor significant differences in mental/physical health status among women based on their disclosure. Future research with larger datasets is needed to build on these findings by confirming results, as well as exploring additional factors, that may more effectively differentiate women who are unlikely to disclose their prenatal marijuana use from those who do disclose their use. KEY POINTS: · Women with higher education were more likely to self-disclose their prenatal marijuana use.. · Women who experienced homelessness were more likely to self-disclose their prenatal marijuana use.. · Self-disclosure of prenatal alcohol use was related to self-disclosure of prenatal marijuana use.
