Household food insecurity is associated with obesogenic health behaviours among a low-income cohort of pregnant women in Boston, MA.

OBJECTIVE: To examine associations of household food insecurity with health and obesogenic behaviours among pregnant women enrolled in an obesity prevention programme in the greater Boston area. DESIGN: Cross-sectional evaluation. Data were collected from structured questionnaires that included a validated two-item screener to assess household food insecurity. We used separate multivariable linear and logistic regression models to quantify the association between household food insecurity and maternal health behaviours (daily consumption of fruits and vegetables, sugar-sweetened beverages and fast food, physical activity, screen time, and sleep), mental health outcomes (depression and stress), hyperglycaemia status and gestational weight gain. SETTING: Three community health centres that primarily serve low-income and racial/ethnic minority patients in Revere, Chelsea and Dorchester, Massachusetts. PARTICIPANTS: Totally, 858 pregnant women participating in the First 1,000 Days program, a quasi-experimental trial. RESULTS: Approximately 21 % of women reported household food insecurity. In adjusted analysis, household food insecurity was associated with low fruit and vegetable intake (ß = -0·31 daily servings; 95 % CI -0·52, -0·10), more screen time (ß = 0·32 daily hours; 95 % CI 0·04, 0·61), less sleep (ß = -0·32 daily hours; 95 % CI -0·63, -0·01), and greater odds of current (adjusted odds ratio (AOR) 4·42; 95 % CI 2·33, 8·35) or past depression (AOR 3·01; 95 % CI 2·08, 4·35), and high stress (AOR 2·91; 95 % CI 1·98, 4·28). CONCLUSIONS: In our sample of mostly low-income, racial/ethnic minority pregnant women, household food insecurity was associated with mental health and behaviours known to increase the likelihood of obesity.

Periviable Decision-Making in a New Era of Parentage: Ethical and Legal Considerations and Provider Perspectives on Shared Decision-making in Diverse Family Structures.

OBJECTIVE: To explore providers' perspectives about decisional authority, conflict resolution, and diverse family structures within the context of periviable delivery (eg, between 22 and 25 weeks of gestation), with the ultimate goal of helping practitioners support, engage, and navigate conflict with parents facing periviable delivery. STUDY DESIGN: Qualitative interviews with 30 neonatologists and obstetricians sought opinions about whether and how a pregnant person's partner should be involved in making periviable treatment decisions and how health care teams should proceed when parents do not agree on a treatment plan. Physicians were asked to consider whether their opinions changed under different scenarios involving marriage, biological relationship, adoption, and surrogacy. RESULTS: Interviews revealed 4 main themes corresponding to providers' perspectives regarding partner involvement and decisional authority: providers care; involvement matters; mom is the priority; and uncertainty and guidance needed. Unique themes arose when discussing diverse family structures. CONCLUSIONS: Shared decision making is optimal in the setting of periviable delivery, where decisions are both preference sensitive and value laden. Our interviews suggest that incorporating the dynamics and impact of partners' involvement in periviable resuscitation decision-making may facilitate more shared, equitable, and high-quality decision-making tailored to the needs of both pregnant people and their partners.

Correlates of sugar-sweetened beverage intake among low-income women during the first 1000 days.

OBJECTIVE: To describe prenatal and postpartum consumption of water, cows' milk, 100 % juice and sugar-sweetened beverages (SSB) among women enrolled in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) programme in New York City (NYC) and to identify correlates of SSB intake in this population. DESIGN: Cross-sectional data were collected from structured questionnaires that included validated beverage frequency questionnaires with the assistance of container samples. The association of maternal and household factors and non-SSB consumption with habitual daily energetic (kJ (kcal)) intake from SSB was assessed by using multivariable median regression. SETTING: WIC programme in NYC, NY. Data were collected in 2017. PARTICIPANTS: 388 pregnant or postpartum women (infant aged <2 years) from the NYC First 1000 Days Study. RESULTS: Median age was 28 years (interquartile range (IQR) 24-34); 94·1 % were Hispanic/Latina, and 31·4 % were pregnant. Overall, 87·7 % of pregnant and 89·1% of postpartum women consumed SSB ≥ once weekly, contributing to a median daily energetic intake of 410 kJ (98 kcal) (IQR (113-904 kJ) 27-216) and 464 kJ (111 kcal) (IQR (163-1013 kJ) 39-242), respectively. In adjusted analyses, only consumption of 100 % juice was associated with greater median energetic intake from SSB (adjusted ß for each additional ounce = 13; 95% CI 8, 31 (3·2; 95 % CI 2·0, 7·3). CONCLUSIONS: Among pregnant and postpartum women in WIC-enrolled families, interventions to reduce SSB consumption should include reduction of 100 % juice consumption as a co-target of the intervention.

Association of vitamin E intake at early childhood with alanine aminotransferase levels at mid-childhood.

The extent to which vitamin E (alpha-tocopherol) intake early in childhood is associated with alanine aminotransferase (ALT) level later in childhood is unknown. The objective of this research is to test the hypothesis that higher alpha-tocopherol intake during early childhood is associated with lower odds of elevated ALT levels during mid-childhood and to examine how body mass index (BMI) influences these relationships. We studied 528 children in Project Viva. Mothers reported child dietary intake at early childhood visits (median 3.1 years) using a validated food frequency questionnaire. At mid-childhood (median 7.6 years), we collected child blood and anthropometric data. The main outcome was elevated sex-specific mid-childhood ALT level (≥22.1 U/L for female children and ≥25.8 U/L for male children). In multivariable logistic regression models, we assessed the association of energy-adjusted alpha-tocopherol intake with ALT levels, adjusting for child age, sex, race/ethnicity, diet, and age-adjusted sex-specific BMI z-score at mid-childhood. Among children in this study, 48% were female, 63% were non-Hispanic white, 19% were non-Hispanic black, and 4% were Hispanic/Latino. Mean alpha-tocopherol intake was 3.7 ± 1.0 mg/day (range, 1.4-9.2) at early childhood. At mid-childhood, mean BMI z-score was 0.41 ± 1.0 units and 22% had an elevated ALT level. In multivariable-adjusted logistic regression models, children with higher early childhood vitamin E intake had lower odds of elevated mid-childhood ALT (adjusted odds ratio [AOR], 0.62; 95% confidence interval [CI], 0.39, 0.99) for quartiles 2-4 compared with the lowest quartile of intake. Findings persisted after accounting for early childhood diet (AOR, 0.62; 95% CI, 0.36, 1.08) and were strengthened after additionally accounting for mid-childhood BMI z-score (AOR, 0.56; 95% CI, 0.32, 0.99). CONCLUSION: In this cohort, higher early childhood intake of alpha-tocopherol was associated with lower odds of elevated mid-childhood ALT level. (Hepatology 2018;67:1339-1347).

Impact of socioeconomic markers on parents' retention of pediatric oncology home care education: A pilot study.

Little is known about the extent to which parents retain the education on how to manage home medical emergencies. We sought to describe retention of pediatric oncology home care education (POHCE) in a cohort of 24 parents of newly diagnosed children with cancer and investigate sociodemographic disparities in this retention. We measured retention using a vignette-based survey instrument. The mean score was 4 (range 0-6, SD = 1.6) and parents with high school only education and those with limited cancer health literacy scored lowest (2.5 and 2.8, respectively). Future POHCE interventions can focus on parents' literacy and education levels as predictors to tailor alternative education strategies.

Parent-centered communication at time of pediatric cancer diagnosis: A systematic review.

There are limited data focused on parental communication needs surrounding the time when a child is diagnosed with cancer. In this systematic review, we synthesized current literature on communication preferences of parents at the time of their child's diagnosis of cancer. We identified 16 studies that yielded 4 major themes parents recognized as important: communication style, content, logistics, and healthcare team. We further identified several concepts that inform parent-centered communication practice. The ensuing pediatric oncology parent-centered communication concept map is meant as a tool to expand providers' communication experience at the time of a new cancer diagnosis.

Does maternity care decision-making conform to shared decision- making standards for repeat cesarean and labor induction after suspected macrosomia?

BACKGROUND: In a national United States survey, we investigated whether crucial shared decision-making standards were met for 2 common maternity care decisions. METHODS: Secondary analysis of Listening to Mothers III. A sequence of validated questions concerning shared decision-making was adapted to 2 maternity care decisions: to induce labor or wait for spontaneous onset of labor among women who were told their baby may be "getting quite large" (N = 349); and for women with 1 or 2 prior cesareans (N = 393), the decision to have a repeat cesarean. RESULTS: Almost half (N = 163; 47%) of women who were told their baby might be large reported engaging in a discussion concerning possible labor induction vs waiting for labor, while a large majority (N = 321; 82%) of women with a prior cesarean discussed the option of a repeat cesarean or a planned vaginal birth after cesarean (VBAC). Women who engaged in discussions received disproportionate information about having the interventions and were more likely to experience the interventions (68% induction, 87% repeat cesarean) than women who did not. After adjustment, women who reported that their provider recommended scheduling a repeat cesarean were 14 times more likely to give birth via cesarean compared with those whose providers recommended planning VBAC (AOR 14.2; 95% CI: 3.2, 63.0). CONCLUSION: Our findings suggest that, for the decisions in question, established standards of shared decision-making are not being reliably implemented in maternity care despite opportunities to do so. Provider recommendations and the disproportionate conveyance of reasons for an intervention appear to be related to higher levels of intervention.

Trajectories of Externalizing and Internalizing Behaviors in Preterm Children Admitted to a Neonatal Intensive Care Unit.

OBJECTIVE: To examine the trajectories of internalizing and externalizing behavior problems of preterm children between 16 months and 6 years of age and predictors of trajectories, including gestational age, child dysregulation, maternal depression, socioeconomic status, and parenting. STUDY DESIGN: This longitudinal study followed 148 children and their mothers from neonatal intensive care unit discharge until 6 years of age. Gestational ages ranged from 23 to 36 weeks. The study included assessment of maternal-reported behavior problems, maternal depression, neonatal and socioeconomic characteristics, and observations of dysregulated behavior and parenting. Trajectories were identified with a semiparametric group-based analytic method, and multinomial logistic regression was used to identify significant risk factors. RESULTS: Three distinct trajectories for preterm children were found for both internalizing and externalizing behavior problems. For the 2 groups with greater behavior problems (groups 1 and 2), trajectories reached their peak between 24 and 36 months of age, then leveled off or decreased. Group 3 showed a stable low level of externalizing behaviors, and a low, but slightly increasing level of internalizing behaviors. Maternal depression, child dysregulation, gestational age, and socioeconomic challenges were identified as risk factors that predicted less optimal behavior problem trajectories. CONCLUSIONS: Children born prematurely followed 1 of 3 distinct developmental trajectories for both internalizing and externalizing behavior problems. The most severe behavior problems started early in development and were associated with increased child dysregulation, maternal depression, and lower socioeconomic status. These findings have implications for screening and monitoring preterm children.

The Prevalence and Impact of Substance Use Disorder and Treatment on Maternal Obstetric Experiences and Birth Outcomes Among Singleton Deliveries in Massachusetts.

Objectives Despite widely-known negative effects of substance use disorders (SUD) on women, children, and society, knowledge about population-based prevalence and impact of SUD and SUD treatment during the perinatal period is limited. Methods Population-based data from 375,851 singleton deliveries in Massachusetts 2003-2007 were drawn from a maternal-infant longitudinally-linked statewide dataset of vital statistics, hospital discharges (including emergency department (ED) visits), and SUD treatment records. Maternal SUD and SUD treatment were identified from 1-year pre-conception through delivery. We determined (1) the prevalence of SUD and SUD treatment; (2) the association of SUD with women's perinatal health service utilization, obstetric experiences, and birth outcomes; and (3) the association of SUD treatment with birth outcomes, using both bivariate and adjusted analyses. Results 5.5% of Massachusetts's deliveries between 2003 and 2007 occurred in mothers with SUD, but only 66% of them received SUD treatment pre-delivery. Women with SUD were poorer, less educated and had more health problems; utilized less prenatal care but more antenatal ED visits and hospitalizations, and had worse obstetric and birth outcomes. In adjusted analyses, SUD was associated with higher risk of prematurity (AOR 1.35, 95% CI 1.28-1.41) and low birth weight (LBW) (AOR 1.73, 95% CI 1.64-1.82). Women receiving SUD treatment had lower odds of prematurity (AOR 0.61, 95% CI 0.55-0.68) and LBW (AOR 0.54, 95% CI 0.49-0.61). Conclusions for Practice SUD treatment may improve perinatal outcomes among pregnant women with SUD, but many who need treatment don't receive it. Longitudinally-linked existing public health and programmatic records provide opportunities for states to monitor SUD identification and treatment.

Effects of Proximity to Supermarkets on a Randomized Trial Studying Interventions for Obesity.

OBJECTIVES: To determine whether proximity to a supermarket modified the effects of an obesity intervention. METHODS: We examined 498 children aged 6 to 12 years with a body mass index (BMI) at or above the 95th percentile participating in an obesity trial in Massachusetts in 2011 to 2013. The practice-based interventions included computerized clinician decision support plus family self-guided behavior change or health coaching. Outcomes were 1-year change in BMI z-score, sugar-sweetened beverage intake, and fruit and vegetable intake. We examined distance to the closest supermarket as an effect modifier. RESULTS: Distance to supermarkets was an effect modifier of 1-year change in BMI z-score and fruit and vegetable intake but not sugar-sweetened beverage intake. With each 1-mile shorter distance to a supermarket, intervention participants increased their fruit and vegetable intake by 0.29 servings per day and decreased their BMI z-score by -0.04 units relative to controls. CONCLUSIONS: Living closer to a supermarket is associated with greater improvements in fruit and vegetable intake and weight status in an obesity intervention.

Infant birthweight in the US: the role of preconception stressful life events and substance use.

The purpose of this study was to determine the relationships among preconception stressful life events (PSLEs), women's alcohol and tobacco use before and during pregnancy, and infant birthweight. Data were from the Early Childhood Longitudinal Study-Birth Cohort (n = 9,350). Data were collected in 2001. Exposure to PSLEs was defined by indications of death of a parent, spouse, or previous live born child; divorce or marital separation; or fertility problems prior to conception. Survey data determined alcohol and tobacco usage during the 3 months prior to and in the final 3 months of pregnancy. We used staged multivariable logistic regression to estimate the effects of women's substance use and PSLEs on the risk of having a very low (<1,500 g, VLBW) or low (1,500-2,499 g, LBW) birthweight infant, adjusting for confounders. Women who experienced any PSLE were more likely to give birth to VLBW infants (adjusted odds ratio [AOR] = 1.35; 95 % confidence interval [CI] = 1.10-1.66) than women who did not experience any PSLE. Compared to women who never smoked, women who smoked prior to conception (AOR = 1.31; 95 % CI = 1.04-1.66) or during their last trimester (AOR = 1.98; 95 % CI = 1.56-2.52) were more likely to give birth to LBW infants. PSLEs and women's tobacco use before and during pregnancy are independent risk factors for having a lower birthweight baby. Interventions to improve birth outcomes may need to address women's health and health behaviors in the preconception period.

Association of missing paternal demographics on infant birth certificates with perinatal risk factors for childhood obesity.

BACKGROUND: The role of fathers in the development of obesity in their offspring remains poorly understood. We evaluated associations of missing paternal demographic information on birth certificates with perinatal risk factors for childhood obesity. METHODS: Data were from the Linked CENTURY Study, a database linking birth certificate and well-child visit data for 200,258 Massachusetts children from 1980-2008. We categorized participants based on the availability of paternal age, education, or race/ethnicity and maternal marital status on the birth certificate: (1) pregnancies missing paternal data; (2) pregnancies involving unmarried women with paternal data; and (3) pregnancies involving married women with paternal data. Using linear and logistic regression, we compared differences in smoking during pregnancy, gestational diabetes, birthweight, breastfeeding initiation, and ever recording a weight for length (WFL) ≥ the 95th percentile or crossing upwards ≥2 WFL percentiles between 0-24 months among the study groups. RESULTS: 11,989 (6.0 %) birth certificates were missing paternal data; 31,323 (15.6 %) mothers were unmarried. In adjusted analyses, missing paternal data was associated with lower birthweight (ß -0.07 kg; 95 % CI: -0.08, -0.05), smoking during pregnancy (AOR 4.40; 95 % CI: 3.97, 4.87), non-initiation of breastfeeding (AOR 0.39; 95 % CI: 0.36, 0.42), and with ever having a WFL ≥ 95th percentile (AOR 1.10; 95 % CI: 1.01, 1.20). Similar associations were noted for pregnancies involving unmarried women with paternal data, but differences were less pronounced. CONCLUSIONS: Missing paternal data on the birth certificate is associated with perinatal risk factors for childhood obesity. Efforts to understand and reduce obesity risk factors in early life may need to consider paternal factors.

The role of perceived discrimination during childhood and adolescence in understanding racial and socioeconomic influences on depression in young adulthood.

OBJECTIVE: To describe levels of perceived lifetime discrimination among young adults and determine its role in understanding this racial/ethnic disparity. STUDY DESIGN: Data were from the Princeton School District study, a 10-year cohort study in which investigators followed 545 non-Hispanic black (46%) and white initial 5-12 graders. Perceived lifetime racial discrimination was assessed with the General Ethnic Discrimination Scale and depressive symptoms with the Center for Epidemiological Studies Depression Scale. Stepped linear and logistic regression analyses assessed the relationships of race/ethnicity, parental education, and quintiles of discrimination to depressive symptoms. Stratification by race/ethnicity explored differences in the role of discrimination in explaining the relationship between parental education and depressive symptoms. RESULTS: Black students from professionally educated families had the greatest discrimination scores, 1.8 times greater than among their white peers (meanblack = 42.1 vs meanwhite = 22.8; P < .0001). Greater parental education was associated with lower depressive symptoms in all regression models. Race/ethnicity became predictive of depressive symptoms only after adjusting for discrimination, which was strongly associated with depressive symptoms. Stratified analysis suggested discrimination accounted for the relationship of parental education to depressive symptoms among whites. Among black subjects, accounting for discrimination unmasked a buffering effect of parental education. CONCLUSIONS: Greater levels of parent education are protective against depression for white youth. However, for black youth, greater parent education confers both risk and protective effects. The high discrimination among black youth from families with college or professionally educated parents overwhelms the protective effect of greater levels of parent education.

The Influence of Children's Cognitive Delay and Behavior Problems on Maternal Depression.

OBJECTIVE: To determine the impact of children's cognitive delay and behavior on maternal depressive symptoms using a large national cohort of US families. STUDY DESIGN: Data were drawn from 2 waves of the nationally representative Early Childhood Longitudinal Study, Birth Cohort (n = 7550). Cognitive delay was defined at age 24 months by the lowest 10th percentile of the Bayley Short Form-Research Edition. At age 4 years, the children's behavior was assessed using the Preschool and Kindergarten Behavior Scales, administered to mothers and primary nonparental child care providers, and maternal depressive symptoms with the Center for Epidemiological Studies Depression Scale. Weighted generalized estimating equation models examined whether the children's behavior mediated the relationship between their cognitive delay status at 24 months and 4-year maternal depressive outcomes. RESULTS: At age 4 years, 26.9% of mothers of children with cognitive delay reported high depressive symptoms, compared with 17.4% of mothers of typically developing children (P < .0001). When the children's behavior was accounted for, the effect of cognitive delay on maternal depressive symptoms decreased by 36% (P < .0001). These findings remained significant when the children's behaviors were assessed by their primary nonparental care providers. CONCLUSION: Caring for a child with a cognitive delay influences maternal depressive symptoms in part through the child's behavior problems. Preventive interventions to ameliorate adverse outcomes for children with cognitive delay and their families should consider the impact of the children's behavior.

Neighborhood disadvantage, preconception stressful life events, and infant birth weight.

OBJECTIVES: We sought to determine whether the effects of preconception stressful life events (PSLEs) on birth weight differed by neighborhood disadvantage. METHODS: We drew our data from the Early Childhood Longitudinal Study, Birth Cohort (2001-2002; n = 9300). We created a neighborhood disadvantage index (NDI) using county-level data from the 2000 US Census. We grouped the NDI into tertiles that represented advantaged, middle advantaged, and disadvantaged neighborhoods. Stratified multinomial logistic regressions estimated the effect of PSLEs on birth weight, controlling for confounders. RESULTS: We found a gradient in the relationship between women's exposure to PSLEs and having a very low birth weight (VLBW) infant by NDI tertile; the association was strongest in disadvantaged neighborhoods (adjusted odd ratio [AOR] = 1.62; 95% confidence interval [CI] = 1.04, 2.53), followed by middle (AOR = 1.39; 95% CI = 1.00, 1.93) and advantaged (AOR = 1.29; 95% CI = 0.91, 1.82) neighborhoods. We observed a similar gradient for women with chronic conditions and among minority mothers. CONCLUSIONS: Women who experienced PSLEs, who had chronic conditions, or were racial/ethnic minorities had the greatest risk of having VLBW infants if they lived in disadvantaged neighborhoods; this suggests exacerbation of risk within disadvantaged environments. Interventions to reduce rates of VLBW should focus on reducing the deleterious effects of stressors and on improving neighborhood conditions.

Racial and Ethnic Differences in the Likelihood of Vaginal Birth After Cesarean Delivery.

BACKGROUND: A major contributor to the increase in cesarean deliveries over recent decades is the decline in vaginal births after cesarean (VBAC). Racial and ethnic disparities in other perinatal outcomes are widely recognized, but few studies have been directed toward racial/ethnic differences in VBAC rates. METHODS: We used the population-based Massachusetts Pregnancy to Early Life (PELL) database to investigate racial/ethnic differences in rates of VBAC for Massachusetts residents with one prior cesarean from 1998 to 2008. RESULTS: The overall VBAC rate was 17.3 percent. After adjusting for demographic, behavioral, and medical risk factors, non-Hispanic Asian mothers had a greater likelihood of VBAC than non-Hispanic white mothers (adjusted risk ratio 1.31 [95% CI 1.23-1.39]). No other racial/ethnic group was significantly different from non-Hispanic whites in adjusted analyses. The likelihood of VBAC also decreased with increasing maternal age. DISCUSSION: Non-Hispanic Asian women are significantly more likely to have VBAC than non-Hispanic white women. Efforts to reduce cesarean delivery rates in the United States should address these disparities. Future research should investigate factors underlying these differences to ensure that all women have access to appropriate maternity care services.

Predictors of alcohol and tobacco use prior to and during pregnancy in the US: the role of maternal stressors.

The purpose of the study was to understand the association between stressful life events prior to conception (PSLEs) and women's alcohol and tobacco use prior to and during pregnancy, and the continuation of such use through pregnancy. Data were from the Early Childhood Longitudinal Study-Birth Cohort (n = 9,350). Data were collected in 2001. Exposure to PSLEs was defined by indications of death of a parent, spouse, or previous live born child, divorce or marital separation, or fertility problems prior to conception. Survey data determined alcohol and tobacco usage during the 3 months prior to and in the final 3 months of pregnancy. Weighted regressions estimated the effect of PSLEs on alcohol and tobacco use at each time point and on the continuation of use, adjusting for confounders. Experiencing any PSLE increased the odds of tobacco use prior to (adjusted odds ratio [AOR] 1.52, 95 % confidence interval (CI) 1.23-1.87) and during pregnancy (AOR 1.57, 95 % CI 1.19-2.07). Women exposed to PSLEs smoked nearly five additional packs of cigarettes in the 3 months prior to pregnancy (97 cigarettes, p = 0.011) and consumed 0.31 additional alcoholic drinks during the last 3 months of pregnancy than unexposed women. PSLEs are associated with tobacco use before pregnancy and alcohol and tobacco use during pregnancy. Alcohol and tobacco screening and cessation services should be implemented prior to and during pregnancy, especially for women who have experienced PSLEs.

Labor and Delivery Experiences of Mothers with Suspected Large Babies.

OBJECTIVE: To characterize the prevalence of and factors associated with clinicians' prenatal suspicion of a large baby; and to determine whether communicating fetal size concerns to patients was associated with labor and delivery interventions and outcomes. METHODS: We examined data from women without a prior cesarean who responded to Listening to Mothers III, a nationally representative survey of women who had given birth between July 2011 and June 2012 (n = 1960). We estimated the effect of having a suspected large baby (SLB) on the odds of six labor and delivery outcomes. RESULTS: Nearly one-third (31.2%) of women were told by their maternity care providers that their babies might be getting "quite large"; however, only 9.9% delivered a baby weighing ≥4000 g (19.7% among mothers with SLBs, 5.5% without). Women with SLBs had increased adjusted odds of medically-induced labor (AOR 1.9; 95% CI 1.4-2.6), attempted self-induced labor (AOR 1.9; 95% CI 1.4-2.7), and use of epidural analgesics (AOR 2.0; 95% CI 1.4-2.9). No differences were noted for overall cesarean rates, although women with SLBs were more likely to ask for (AOR 4.6; 95% CI 2.8-7.6) and have planned (AOR 1.8; 95% CI 1.0-4.5) cesarean deliveries. These associations were not affected by adjustment for gestational age and birthweight. CONCLUSIONS FOR PRACTICE: Only one in five US women who were told that their babies might be getting quite large actually delivered infants weighing ≥4000 g. However, the suspicion of a large baby was associated with an increase in perinatal interventions, regardless of actual fetal size.

Determinants of cesarean delivery in the US: a lifecourse approach.

This study takes a lifecourse approach to understanding the factors contributing to delivery methods in the US by identifying preconception and pregnancy-related determinants of medically indicated and non-medically indicated cesarean section (C-section) deliveries. Data are from the Early Childhood Longitudinal Study-Birth Cohort, a nationally representative, population-based survey of women delivering a live baby in 2001 (n = 9,350). Three delivery methods were examined: (1) vaginal delivery (reference); (2) medically indicated C-section; and (3) non-medically indicated C-sections. Using multinomial logistic regression, we examined the role of sociodemographics, health, healthcare, stressful life events, pregnancy complications, and history of C-section on the odds of medically indicated and non-medically indicated C-sections, compared to vaginal delivery. 74.2 % of women had a vaginal delivery, 11.6 % had a non-medically indicated C-section, and 14.2 % had a medically indicated C-section. Multivariable analyses revealed that prior C-section was the strongest predictor of both medically indicated and non-medically indicated C-sections. However, we found salient differences between the risk factors for indicated and non-indicated C-sections. Surgical deliveries continue to occur at a high rate in the US despite evidence that they increase the risk for morbidity and mortality among women and their children. Reducing the number of non-medically indicated C-sections is warranted to lower the short- and long-term risks for deleterious health outcomes for women and their babies across the lifecourse. Healthcare providers should address the risk factors for medically indicated C-sections to optimize low-risk delivery methods and improve the survival, health, and well-being of children and their mothers.

Impact of county disadvantage on behavior problems among US children with cognitive delay.

OBJECTIVES: We investigated relationships among cognitive delay, community factors, and behavior problems over 2 years in early childhood with a national sample of US families. METHODS: Data were from 3 waves of the Early Childhood Longitudinal Study, Birth Cohort (2001-2005; n = 7650). We defined cognitive delay as the lowest 10% of mental scores from the Bayley Short Form-Research Edition, administered at 9 and 24 months. At 24 months, we classified children as typically developing or as having resolved, newly developed, or persistent cognitive delays. Behavior was measured at age 4 years with the Preschool and Kindergarten Behavior Scales (range = 0-36). Community factors included perceived neighborhood safety and an index of county disadvantage. RESULTS: Behavior scores at age 4 years (mean = 12.4; SD = 4.9) were higher among children with resolved (Β = 0.70; SE = 0.20), newly developed (Β = 1.92; SE = 0.25), and persistent (Β = 2.96; SE = 0.41) cognitive delays than for typically developing children. The interaction between county disadvantage and cognitive delay status was statistically significant (P < .01), suggesting that county disadvantage was particularly detrimental for children with persistent delays. CONCLUSIONS: The community context may provide an opportunity for public health interventions to improve the behavioral health of children with cognitive delays.
