Bastola K, Koponen P, Gissler M, Kinnunen TI. Differences in caesarean delivery and neonatal outcomes among women of migrant origin in Finland: A population-based study. Paediatr Perinat Epidemiol 2020; 34:12-20. [PMID: 31960477 DOI: 10.1111/ppe.12611] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Revised: 09/27/2019] [Accepted: 10/13/2019] [Indexed: 01/23/2023]
Abstract
BACKGROUND In Finland, limited information is available on neonatal disparities among women of migrant origin. OBJECTIVE This study investigated differences in caesarean delivery and neonatal outcomes between women of migrant origin and Finnish women in Finland. METHODS The study was based on nationwide data from the Medical Birth Register of Finland. Our study included information on the most recent singleton birth of women delivering between January 2004 and December 2014 (N = 382 233). Women were classified into nine regional categories based on their country of origin. Generalized linear models were used to describe associations between country of origin and pregnancy outcomes adjusted for maternal age, socio-economic status, pre-pregnancy body mass index, parity, marital status, smoking during pregnancy, and delivery year. Finnish women were the reference group. RESULTS Among the study population, almost 92% of women were of Finnish origin; the remaining 8% were of migrant origin. Among the migrant women, those of Russian/former USSR origin were the largest group (n = 11 994); the smallest group was women of Latin American/Caribbean origin (n = 739). Compared with Finnish women, women of sub-Saharan African, South Asian, and East Asian origin were at greater risk of emergency caesarean delivery, preterm birth, low birthweight, and lower five-minute Apgar scores for newborns. Latin American/Caribbean-origin women were at increased risk of both elective and emergency caesarean delivery and lower five-minute Apgar scores compared with Finnish women. Women of Russian/former USSR origin overall had a lower risk of caesarean delivery and poor neonatal outcomes compared with Finnish women. CONCLUSIONS We identified sub-Saharan African, South Asian, and East Asian women as higher-risk groups, and women from Russia/former USSR as a lower-risk group, for emergency caesarean delivery and poor neonatal outcome compared with Finnish women. More research is needed to identify the reasons for these differences by country of origin in Finland.

Abstract
In the United States, ethnic minority status and low socioeconomic status both confer greater risk of premature birth. These sociodemographic factors also contribute to a greater risk of postpartum depression, as does giving birth prematurely. Considering the known adverse effects of postpartum depression on children's development, NICU-based mental health services for these high-risk mothers is an important public health intervention. Although counseling and educational interventions in the NICU have been shown to decrease maternal depressive symptoms, these interventions require parental presence on the unit. Mothers of both low socioeconomic and ethnic minority status face systemic barriers that may prevent them from visiting their infants, such as lack of paid leave, transportation, and childcare. We propose directions for future research with the aim of increasing access to services. Directions include brief individual therapy, telehealth, and increasing the psychosocial support skills of other health professionals. Potential barriers to implementation are discussed.

Abstract
Hoynes, Miller, and Simon (2015), henceforth HMS, report that the national expansion of the Earned Income Tax Credit (EITC) is associated with decreases in low birth weight. We question their findings. HMS's difference-in-differences estimates are unidentified in some comparisons, while failed placebo tests undermine others. Their effects lack a plausible mechanism as the association between the EITC and prenatal smoking also fails placebo tests. We contend that the waning of the crack epidemic is a possible confound, but we show that any number of policies directed at poor women also eliminate the effect of the EITC when aggregated to the national level. Identifying small, causal effects of a national policy at a single point in time is exceedingly challenging.

Abstract
Objective: To determine whether the Institute Of Medicine's (IOM) 2009 guidelines for weight-gain during pregnancy are predictive of maternal and infant outcomes in ethnic minority populations.Methods: We designed a population-based study using administrative data on 181,948 women who delivered live singleton births in Washington State between 2006-2008. We examined risks of gestational hypertension, preeclampsia/eclampsia, cesarean delivery, and extended hospital stay in White, Black, Native-American, East-Asian, Hispanic, South-Asian and Hawaiian/Pacific islander women according to whether they gained more or less weight during pregnancy than recommended by IOM guidelines. We also examined risks of neonatal outcomes including Apgar score <7 at 5 min, admission to NICU, requirement for ventilation, and a diagnosis of small or large for gestational age at birth.Results: Gaining too much weight was associated with increased odds for gestational hypertension (adjusted OR (aOR) ranged between 1.53-2.22), preeclampsia/eclampsia (aOR 1.44-1.81), cesarean delivery (aOR 1.07-1.38) and extended hospital stay (aOR 1.06-1.28) in all ethnic groups. Gaining too little weight was associated with decreased odds for gestational hypertension and delivery by cesarean section in Whites, Blacks and Hispanics. Gaining less weight or more weight than recommended was associated with increased odds for small for gestational age and large for gestational age infants respectively, in all ethnic groups.Conclusions: Adherence to the 2009 IOM guidelines for weight gain during pregnancy reduces risk for various adverse maternal outcomes in all ethnic groups studied. However, the guidelines were less predictive of infant outcomes with the exception of small and large for gestational age.Abbreviations: GWG: Gestational weight gain; IOM/NRC; Institute of Medicine and National Research Council; NICU: Neonatal intensive care need for ventilation; SGA: Small for gestational age; LGA: Large for gestational age; BERD: Birth Events Records Database; CHARS: Comprehensive Hospital Discharge Abstract Reporting System; ICD: International Classification of Disease; LMP: Last menstrual period; OR: Odds ratio.

Abstract
Smoking during pregnancy causes various maternal and fetal health problems. Although there are considerable differences in maternal smoking proportions between localities, only a few studies have investigated the effects of regional characteristics on maternal smoking behavior. This study aimed to clarify the association between maternal smoking during pregnancy and individual and regional characteristics. We used data from a large nationwide birth cohort study in Japan that consisted of information on 20,267 women with children aged 3–4 months. The multilevel regression model was used to examine the association between smoking behavior during pregnancy and individual and regional characteristics. On multilevel analysis, late birth order, young age of the mother at birth, low birth weight, low economic status, husband’s smoking during pregnancy, maternal alcohol consumption during pregnancy, absence of a pregnancy counselor, and lack of participation in local events for childrearing were significantly associated with maternal smoking behavior during pregnancy at the individual level. Meanwhile, a high unemployment rate and a high number of nurseries were significantly associated with maternal smoking behavior during pregnancy at the regional level. In conclusion, we showed the relation between maternal smoking during pregnancy and the individual- and regional-level characteristics.

Abstract
Secondhand smoke exposure is a major public health risk that is especially harmful to the developing brain, but it is unclear if early exposure affects brain structure during middle age and older adulthood. Here we analyzed brain MRI data from the UK Biobank in a population-based sample of individuals (ages 44-80) who were exposed (n = 2510) or unexposed (n = 6079) to smoking around birth. We used robust statistical models, including quantile regressions, to test the effect of perinatal smoke exposure (PSE) on cortical surface area (SA), thickness, and subcortical volumes. We hypothesized that PSE would be associated with cortical disruption in primary sensory areas compared to unexposed (PSE-) adults. After adjusting for multiple comparisons, SA was significantly lower in the pericalcarine (PCAL), inferior parietal (IPL), and regions of the temporal and frontal cortex of PSE+ adults; these abnormalities were associated with increased risk for several diseases, including circulatory and endocrine conditions. Sensitivity analyses conducted in a hold-out group of healthy participants (exposed, n = 109, unexposed, n = 315) replicated the effect of PSE on SA in the PCAL and IPL. Collectively our results show a negative, long term effect of PSE on sensory cortices that may increase risk for disease later in life.

Abstract
BackgroundData on the effects of extremely low frequency electromagnetic fields (ELF-EMF) on pregnancy outcomes are inconclusive.ObjectiveTo study the relation between maternal cumulative exposure to ELF-EMF during pregnancy and the risk of prematurity or small for gestational age (SGA) in a pooled analysis of two French birth cohorts.MethodsElfe and Epipage2 are both population-based birth cohorts initiated in 2011 and included 18 329 and 8400 births, respectively. Health data and household, mother and child characteristics were obtained from medical records and questionnaires at maternity and during follow-up. A job exposure matrix was used to assess cumulative exposure to ELF-EMF during three periods: (1) until 15 weeks of gestation, (2) until 28 weeks of gestation and (3) until 32 weeks of gestation. Analyses were restricted to single live births in mainland France and to mothers with documented jobs (N=19 894). Adjusted logistic regression models were used.ResultsAccording to the period studied, 3.2%–4% of mothers were classified as highly exposed. Results were heterogeneous. Increased risks of prematurity were found among low exposed mothers for the three periods, and no association was observed among the most exposed (OR1=0.92 (95% CI 0.74 to 1.15); OR2=0.98 (95% CI 0.80 to 1.21); OR3=1.14 (95% CI 0.92 to 1.41)). For SGA, no association was observed with the exception of increased risk among the low exposed mothers in period 2 and the most exposed in period 3 (OR=1.25 (95% CI 1.02 to 1.53)).ConclusionSome heterogeneous associations between ELF-EMF exposure and prematurity and SGA were observed. However, due to heterogeneity (ie, their independence regarding the level of exposure), associations cannot be definitely explained by ELF-EMF exposure.

Abstract
OBJECTIVE To describe the long-term neurodevelopmental and cognitive outcomes for children born preterm. STUDY DESIGN In this retrospective cohort study, information on children born in Western Australia between 1983 and 2010 was obtained through linkage to population databases on births, deaths, and disabilities. For the purpose of this study, disability was defined as a diagnosis of intellectual disability, autism, or cerebral palsy. The Kaplan-Meier method was used to estimate the probability of disability-free survival up to age 25 years by gestational age. The effect of covariates and predicted survival was examined using parametric survival models. RESULTS Of the 720 901 recorded live births, 12 083 children were diagnosed with disability, and 5662 died without any disability diagnosis. The estimated probability of disability-free survival to 25 years was 4.1% for those born at gestational age 22 weeks, 19.7% for those born at 23 weeks, 42.4% for those born at 24 weeks, 53.0% for those born at 25 weeks, 78.3% for those born at 28 weeks, and 97.2% for those born full term (39-41 weeks). There was substantial disparity in the predicted probability of disability-free survival for children born at all gestational ages by birth profile, with 5-year estimates of 4.9% and 10.4% among Aboriginal and Caucasian populations, respectively, born at 24-27 weeks and considered at high risk (based on low Apgar score, male sex, low sociodemographic status, and remote region of residence) and 91.2% and 93.3%, respectively, for those at low risk (ie, high Apgar score, female sex, high sociodemographic status, residence in a major city). CONCLUSIONS Apgar score, birth weight, sex, socioeconomic status, and maternal ethnicity, in addition to gestational age, have pronounced impacts on disability-free survival.

Abstract
Poor consumption of balanced diet could result in poor weight gain during pregnancy increasing the risk of premature delivery, low birth weight, and birth defects. To assess the nutritional status and dietary intake of pregnant women in rural areas of Vhembe district. A cross-sectional descriptive study was carried out among 240pregnant women who were selected conveniently from 16 clinics in Vhembe District. An interviewer-administered questionnaire was used for data collection. Anthropometric measurements were measured following standard techniques. Data on dietary intake were collected using Food Frequency Questionnaire (FFQ). Permission and clearance were obtained and participant's rights were respected. Majority (78%) had secondary educational level while 19.5% had tertiary educational level. The mean energy and carbohydrate intake was 2248 Kcal and 372.1 g, respectively. Prevalence of underweight, overweight and obese using BMI was 16.3%, 24.2%, and 8.7% respectively. Dietary intake of the study participants showed that the intake of energy, fats, carbohydrates and vitamin C met the Recommended Dietary Allowance (RDA) values. The mean intake of protein was 30.2 ± 18.2 g. However, micronutrients like zinc, iron, magnesium, calcium including Vitamin A, B1 and B2 did not meet the RDA values in the current study. Despite government's programs to ensure adequate consumption of micronutrients and proper weight gain during pregnancy, malnutrition and insufficient consumption of micronutrients remains a major public health problem in South Africa. Improving nutritional status during pregnancy should follow an integrated approach tackling both malnutrition and micronutrient deficiencies at the same time considering the behavioral approach which will improve child survival and maternal health.

Abstract
OBJECTIVES Ethnic enclaves are ethnically, spatially, and socially distinct communities that may promote health through access to culturally appropriate resources and reduced exposure to discrimination. This study examined ethnic enclave residence and pregnancy outcomes among Asian/Pacific Islander (API) women in the USA. DESIGN We examined 9206 API births in the Consortium on Safe Labor (2002-2008). Ethnic enclaves were defined as hospital regions with high percentage of API residents (> 4%), high dissimilarity index (> 0.41; distribution of API and white residents within a geographic area), and high isolation index (> 0.03; interaction between API and white residents in an area). Gestational diabetes mellitus (GDM), preterm birth (PTB), small for gestational age (SGA), and smoking and alcohol use during pregnancy were reported in medical records supplemented with ICD-9 codes. Hierarchical logistic regression models estimated associations between ethnic enclaves and pregnancy outcomes, adjusted for maternal factors, area-level poverty, and air pollution. RESULTS Women in enclaves had lower odds of GDM (OR 0.61; 95%CI 0.45, 0.82), PTB (OR 0.74; 95%CI 0.56, 0.99), and SGA (OR 0.68; 95%CI 0.52, 0.89) compared with women in non-enclaves. Prenatal smoking and alcohol use appeared less likely in enclaves, but estimates were imprecise. Within enclaves, about 10.5% of homes speak an API language, compared with 6.0% in non-enclaves. The mean percent of foreign-born API populations was 67.4% in enclaves and 68.8% in non-enclaves. CONCLUSIONS API women residing in ethnic enclaves had better pregnancy outcomes than API women residing in non-enclave areas. Access to culturally appropriate social supports and resources may be important for health promotion among API populations.

Abstract
Background Despite public funding of midwifery care, people of low-socioeconomic status are less likely to access midwifery care in Ontario, Canada, but little is known about barriers that they experience in accessing midwifery care. The purpose of this study was to examine the barriers and facilitators to accessing midwifery care experienced by people of low-socioeconomic status. Methods A qualitative descriptive study design was used. Semi-structured interviews were conducted with 30 pregnant and post-partum people of low-socioeconomic status in Hamilton, Ontario from January to May 2018. Transcribed interviews were coded using open coding techniques and thematically analyzed. Results We interviewed 13 midwifery care recipients and 17 participants who had never received care from midwives. Four themes arose from the interviews: “I had no idea…”, “Babies are born in hospitals”, “Physicians as gateways into prenatal care”, and “Why change a good thing?”. Participants who had not experienced midwifery care had minimal knowledge of midwifery and often had misconceptions about midwives’ scope of practice and education. Prevailing beliefs about pregnancy and birth, particularly concerns about safety, drove participants to seek care from a physician. Physicians are the entry point into the health care system for many, yet few participants received information about midwifery care from physicians. Participants who had experienced midwifery care found it to be an appropriate match for the needs of people of low socioeconomic status. Word of mouth was a primary source of information about midwifery and the most common reason for people unfamiliar with midwifery to seek midwifery care. Conclusions Access to midwifery care is constrained for people of low-socioeconomic status because lack of awareness about midwifery limits the approachability of these services, and because information about midwifery care is often not provided by physicians when pregnant people first contact the health care system. For people of low-socioeconomic status, inequitable access to midwifery care may be exacerbated by lack of knowledge about midwifery within social networks and a tendency to move passively through the health care system which traditionally favours physician care. Targeted efforts to address this issue are necessary to reduce disparities in access to midwifery care.

Associations between Maternal Health-Related Quality of Life during Pregnancy and Birth Outcomes: The Generation R Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16214243. [PMID: 31683775 PMCID: PMC6862207 DOI: 10.3390/ijerph16214243] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/27/2019] [Revised: 10/30/2019] [Accepted: 10/30/2019] [Indexed: 12/17/2022]
Abstract
The objective of this study was to assess associations between maternal health-related quality of life (HRQoL) in early, mid-, and late pregnancy and birth outcomes and to assess the differences in birth outcomes between subgroups of mothers reporting relatively “low” and relatively “high” HRQoL. HRQoL was measured by the 12-item Short Form Health Survey in early (n = 6334), mid- (n = 6204), and late pregnancy (n = 6048) in a population-based mother and child cohort; Physical and Mental Component Summary (PCS/MCS) scores were calculated. Birth outcomes included pregnancy duration, preterm birth, birth weight, low birth weight, and small for gestational age. We defined very high PCS/MCS scores as the >90th percentile and very low score as the <10th percentile. The lower PCS score in late pregnancy was significantly associated with a higher chance of having small-for-gestational-age birth (per 10 points: OR = 1.20, 95% CI: 1.08, 1.33, p value = 0.0006). In early, mid-, and late pregnancy, the subgroup mothers with a low MCS score had infants with a lower average birth weight than those with very high scores (p < 0.05). The association between higher physical HRQoL in late pregnancy and a higher chance of having small-for-gestational-age birth needs further research. The role of mother’s mental HRQoL during pregnancy and the potential consequences for the child require further study.

Prev Med Rep 2019; 16:100985.

Abstract
Local governments play an integral role in providing public services to their residents, yet the population health benefits are frequently overlooked, especially when services are outside the traditional health domain. With data from the U.S. Census of Governments and national birth records (spanning from 1992 to 2014), we examined whether local government expenditures on parks and recreation services (PRS) and housing and community development (HCD) predicted county low birth weight outcomes (population incidence and black-white disparities). Hypotheses were tested using bias-corrected county-by-period fixed effects models in a sample of 956 U.S. counties with a total of 3619 observations (observations were defined as three-year pooled estimates), representing 24 million births. Adjusting for prior county low birth weight incidence, levels of total operational, health, and hospital expenditures, and time-varying county sociodemographics, an increase in per capita county PRS expenditures of $50 was associated with 1.25 fewer low birth weight cases per 1000. Change in county HCD expenditures was not associated with low birth weight incidence, and, contrary to hypotheses, neither expenditure type was linked to county black-white disparities. Further examination of the benefits to birth outcomes from increasing parks and recreation services is warranted. Rising parks and recreation expenditures are linked to declining low birth weight. Housing and community expenditures are not associated with low birth weight. ‘Health’ was the only expenditure type linked to black-white perinatal disparities. Benefits of parks and recreation services may include healthier birth outcomes.

Mediating roles of preterm birth and restricted fetal growth in the relationship between maternal education and infant mortality: A Danish population-based cohort study. PLoS Med 2019; 16:e1002831. [PMID: 31199800 PMCID: PMC6568398 DOI: 10.1371/journal.pmed.1002831] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2018] [Accepted: 05/20/2019] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Socioeconomic disparities in infant mortality have persisted for decades in high-income countries and may have become stronger in some populations. Therefore, new understandings of the mechanisms that underlie socioeconomic differences in infant deaths are essential for creating and implementing health initiatives to reduce these deaths. We aimed to explore whether and the extent to which preterm birth (PTB) and small for gestational age (SGA) at birth mediate the association between maternal education and infant mortality. METHODS AND FINDINGS We developed a population-based cohort study to include all 1,994,618 live singletons born in Denmark in 1981-2015. Infants were followed from birth until death, emigration, or the day before the first birthday, whichever came first. Maternal education at childbirth was categorized as low, medium, or high. An inverse probability weighting of marginal structural models was used to estimate the controlled direct effect (CDE) of maternal education on offspring infant mortality, further split into neonatal (0-27 days) and postneonatal (28-364 days) deaths, and portion eliminated (PE) by eliminating mediation by PTB and SGA. The proportion eliminated by eliminating mediation by PTB and SGA was reported if the mortality rate ratios (MRRs) of CDE and PE were in the same direction. The MRRs between maternal education and infant mortality were 1.63 (95% CI 1.48-1.80, P < 0.001) and 1.19 (95% CI 1.08-1.31, P < 0.001) for low and medium versus high education, respectively. The estimated proportions of these total associations eliminated by reducing PTB and SGA together were 55% (MRRPE = 1.27, 95% CI 1.15-1.40, P < 0.001) for low and 60% (MRRPE = 1.11, 95% CI 1.01-1.22, P = 0.037) for medium versus high education. The proportions eliminated by eliminating PTB and SGA separately were, respectively, 46% and 11% for low education (versus high education) and 48% and 13% for medium education (versus high education). PTB and SGA together contributed more to the association of maternal educational disparities with neonatal mortality (proportion eliminated: 75%-81%) than with postneonatal mortality (proportion eliminated: 21%-23%). Limitations of the study include the untestable assumption of no unmeasured confounders for the causal mediation analysis, and the limited generalizability of the findings to other countries with varying disparities in access and quality of perinatal healthcare. CONCLUSIONS PTB and SGA may play substantial roles in the relationship between low maternal education and infant mortality, especially for neonatal mortality. The mediating role of PTB appeared to be much stronger than that of SGA. Public health strategies aimed at reducing neonatal mortality in high-income countries may need to address socially related prenatal risk factors of PTB and impaired fetal growth. The substantial association of maternal education with postneonatal mortality not accounted for by PTB or SGA could reflect unaddressed educational disparities in infant care or other factors.

Abstract
BACKGROUND The health of pregnant women and their fetuses are especially sensitive to socioeconomic conditions. This study analyzes the impact of maternal socioeconomic status (SES), evaluated by occupation and maternal education level, in preterm births (PTBs) and in small for gestational age (SGA) fetuses, considering the effect of the potential mediating factors on the SES and birth outcomes. METHODS A total of 2497 mother/newborn dyads from the INMA-Spain project were studied. We examined maternal occupation and education in relation to PTB and SGA along with covariate data, using logistic regression analysis. Adjusted models for each of the outcome variables in relation to SES indicators were estimated, considering potential mediating factors. RESULTS About 4.7% of babies were PTB and 9.7% SGA. Full adjusted logistic regression models showed similar odds ratio (OR) for SGA in both SES indicators. Manual working women or without university studies had higher risk of SGA than their counterpart groups (OR = 1.39% CI = 1.03-1.88 and OR = 1.39% CI = 1.00-2.00, respectively). Likewise, mothers with a manual occupation were at more risk of PTB than those with a non-manual occupation (OR = 1.74 95% CI = 1.13-2.74), but there was no association between education and PTB. Smoking, pre-pregnancy BMI and underweight gain during pregnancy were significantly associated to SGA births. The mother's age, presence of complications and overweight gain during pregnancy were related to PTB. CONCLUSION The mother's socioeconomic disadvantage was consistently associated with birth outcomes giving rise to intergenerational transmission of health inequalities. Reducing inequalities requires eliminating the upstream causes of poverty itself.

Urquia ML, Wall-Wieler E, Ruth CA, Liu X, Roos LL. Revisiting the association between maternal and offspring preterm birth using a sibling design. BMC Pregnancy Childbirth 2019; 19:157.

Abstract
Background Previous studies have reported an intergenerational association between maternal and offspring preterm birth (PTB) but the nature of the association remains unclear. We assessed the association between maternal and offspring preterm birth using a quasi-experimental sibling design and distinguishing between preterm birth types. Methods We conducted a retrospective intergenerational cohort study of 39,573 women born singleton in Manitoba, Canada (1980–2002) who gave birth to 79,198 singleton infants (1995–2016). To account for familial confounding we defined a subcohort of 1033 sisters with discordant PTB status who subsequently gave birth and compared offspring PTB rates between 2499 differentially exposed cousins using log-binomial fixed-effects generalized estimating equation models. PTB was defined as a delivery < 37 gestation weeks, divided into spontaneous and provider-initiated. Results In the population cohort, mothers born preterm were more likely to give birth preterm [Adjusted Relative Risk (ARR): 1.39; 95% Confidence Interval (CI): 1.25, 1.54] and very preterm birth [ARR: 1.76; 95% CI: 1.29, 2.41]. However, in the siblings cohort, the intergenerational association was not apparent among births to sisters with discordant PTB status [ARR: 1.02; 95% CI: 0.77, 1.34 for preterm birth and ARR: 0.88; 95% CI: 0.38, 2.02 for very preterm birth]. Mothers born at term with a sister born preterm had a similarly elevated risk of delivering a preterm infant (10%) than their preterm sisters. Intergenerational patterns were observed for spontaneous PTB but not for provider-initiated PTB. Conclusions Our findings suggest that it is not the fact of having been born preterm that puts women at higher risk of delivering preterm, but the fact of having been born to a mother who ever delivered preterm. Consideration of a female family history of PTB may better identify women at higher risk of preterm delivery than relying on maternal preterm birth status alone. Further research may benefit from distinguishing preterm birth types.

Abstract
Background We investigated whether the risk of cerebral palsy (CP) in the child varies by parents’ socioeconomic status, in Denmark and Norway. Methods We included almost 1.3 million children born in Demark during 1981–2007 and 2.4 million children born in Norway during 1967–2007, registered in the Medical Birth registries. Data on births were linked to Statistics Denmark and Norway to retrieve information on parents’ education and relationship status and, in Denmark, also income. CP diagnoses were obtained from linkage with national registries. We used multivariate log-binominal regression models to estimate relative risk (RR) of CP according to parental socioeconomic status. Results There was a strong trend of decreasing risk of CP with additional education of both the mother and the father. These trends were nearly identical for the two parents, with a one-third reduction in risk for those with the highest education compared with parents with the lowest education. When both parents had high education, risk of CP was further reduced (RR 0.58, 0.53–0.63). Women with partners had a reduction in risk (RR 0.79, 0.74–0.85) compared with single mothers overall. Risk patterns were stable over time, across countries and within spastic bilateral and unilateral CP. Household income was not associated with risk of CP. Conclusions Risk of CP in two Scandinavian countries was lower among educated parents and mothers with a partner, but unrelated to income. Factors underlying this stable association with education are unknown, but could include differences in potentially modifiable lifestyle factors and health behaviours.

Abstract
BACKGROUND Social inequalities in the prevalence of childhood overweight and obesity are well-established, but less is known about when the social gradient first emerges and how it evolves across childhood and adolescence. OBJECTIVE This study examines maternal education differentials in children's body mass trajectories in infancy, childhood and adolescence using data from four contemporary European child cohorts. METHODS Prospective data on children's body mass index (BMI) were obtained from four cohort studies-Generation XXI (G21-Portugal), Growing Up in Ireland (GUI) infant and child cohorts, and the Millennium Cohort Study (MCS-UK)-involving a total sample of 41,399 children and 120,140 observations. Children's BMI trajectories were modelled by maternal education level using mixed-effect models. RESULTS Maternal educational inequalities in children's BMI were evident as early as three years of age. Children from lower maternal educational backgrounds were characterised by accelerated BMI growth, and the extent of the disparity was such that boys from primary-educated backgrounds measured 0.42 kg/m2 (95% CI 0.24, 0.60) heavier at 7 years of age in G21, 0.90 kg/m2 (95% CI 0.60, 1.19) heavier at 13 years of age in GUI and 0.75 kg/m2 (95% CI 0.52, 0.97) heavier in MCS at 14 years of age. The corresponding figures for girls were 0.71 kg/m2 (95% CI 0.50, 0.91), 1.31 kg/m2 (95% CI 1.00, 1.62) and 0.76 kg/m2 (95% CI 0.53, 1.00) in G21, GUI and MCS, respectively. CONCLUSIONS Maternal education is a strong predictor of BMI across European nations. Socio-economic differentials emerge early and widen across childhood, highlighting the need for early intervention.

Abstract
OBJECTIVE Adolescent pregnancy is a significant public health issue in Canada. Current evidence highlights the individual role of social determinants of health such as maternal residence and socioeconomic status (SES) on teen pregnancy outcomes. This study evaluated the joint association between residence/SES and adverse adolescent pregnancy outcomes. METHODS This was a population-based retrospective cohort study of all singleton, live deliveries (2010-2015) from women aged 15 to 19 who were registered in the Alberta Perinatal Health Program. Information on maternal residence and SES was extracted from the Pampalon Material Deprivation Index data set. The study categorized mothers into four risk dyads: rural/high SES, rural/low SES, urban/high SES, and urban/low SES. Adjusted odds ratios (ORs) of adverse pregnancy outcomes were calculated in logistic regression models (Canadian Task Force Classification II-2). RESULTS A total of 9606 births from adolescent mothers were evaluated. Thirty percent of adolescent mothers were classified as urban/high SES; 27% were urban/low SES; 7% were rural/high SES; and 36% were placed in the rural/low SES category. Compared with urban/high SES mothers, rural/low SES mothers had increased odds of postpartum hemorrhage (OR 1.57; 95% confidence interval [CI] 1.41-1.74), operative vaginal delivery (OR 1.37; 95% CI 1.18-1.60), Caesarean section (OR 1.39; 95% CI 1.19-1.62), large for gestational age infants (OR 1.39; 95% CI 1.16-1.66), low birth weight (OR 1.11; 95% CI 1.07-1.65), and preterm birth (OR 1.48; 95% CI 1.17-1.87). CONCLUSION Rural pregnant adolescents of low SES have the highest odds for adverse pregnancy outcomes. Social determinants of health that affect adolescent pregnancies need further examination to identify high-risk subgroups and understand pathways to health disparities in this vulnerable population.

Effect of preconception low dose aspirin on pregnancy and live birth according to socioeconomic status: A secondary analysis of a randomized clinical trial. PLoS One 2019; 14:e0200533. [PMID: 30998747 PMCID: PMC6472730 DOI: 10.1371/journal.pone.0200533] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2017] [Accepted: 06/25/2018] [Indexed: 01/10/2023] Open
Abstract
Low socioeconomic status (SES) is associated with adverse pregnancy outcomes and infertility. Low-dose aspirin (LDA) was shown to improve livebirth rates in certain subsets of women, and therefore, may impact pregnancy rates differentially by SES status. Therefore, the aim of the current study was to examine whether daily preconception-initiated LDA affects rates of pregnancy, livebirth, and pregnancy loss differently across strata of socioeconomic status (SES). This is a secondary analysis of The Effects of Aspirin in Gestation and Reproduction (EAGeR) Trial, a multisite, block- randomized, placebo-controlled trial conducted at four U.S. medical centers (n = 1,228, 2007–2012). Women attempting spontaneous conception with a history of pregnancy loss were randomly allocated preconception to 81mg of aspirin + 400mcg of folic acid (n = 615) or placebo + 400mcg of folic acid (n = 613). Study medication was administered for six menstrual cycles or until 36 weeks’ gestation if pregnancy was achieved. For this analysis, women were stratified by SES, which included income (low, mid, high) and a combined grouping of education and income (low-low, low-high, high-low, high-high). Log binomial models with robust variance estimated risks of pregnancy, livebirth, and pregnancy loss for LDA versus placebo. LDA increased pregnancy and livebirth rates (RR 1.23, 95% CI: 1.03, 1.45) in the high-income, but not mid- or low-income groups. LDA increased pregnancy rates in both the low education-low income group (RR 1.22, 95% CI: 1.02, 1.46) and the high education-high income group (RR 1.23, 95%CI: 1.06, 1.42), with no effect observed in mid-SES groupings. LDA, a low-cost and widely available treatment, may be particularly beneficial to women at the highest and lowest ends of the socioeconomic spectrum, though underlying mechanisms of this disparity are unclear. Confirming these findings and identifying factors which may modulate the effectiveness of LDA will ultimately facilitate personalized clinical care and improvements in population-level reproductive health.

Abstract
Objectives High infant mortality rates among American Indians in North Dakota contribute to a 20-year gap in average age at death compared to whites. Geographic- and race-specific health disparities data to drive policy making and interventions are not well disseminated. The current study examines prenatal risk factors and birth outcomes between American Indian and whites in North Dakota. Methods A retrospective descriptive analysis of North Dakota live births from 2007 to 2012 was conducted. Period prevalence and prevalence ratios were calculated. Results The infant mortality rate from 2010 to 2012 for infants born to American Indian women was 3.5 times higher than whites. Racial disparities existed in education, teen births, tobacco use during pregnancy, and breastfeeding initiation. Disparities widened for inadequate prenatal care, illegal drug use during pregnancy, and infant mortality from 2007-2009 to 2010-2012 and narrowed for sexually transmitted infections and alcohol use during pregnancy. Conclusions for Practice American Indians are disproportionately affected by poor pregnancy and birth outcomes in North Dakota. Future geographic-specific American Indian research is warranted to aid current and future public health interventions.

Abstract
OBJECTIVE To investigate to what extent paternal involvement and support during pregnancy were associated with preterm (PTB) and small-for-gestational age (SGA) births. METHODS Using data from the Boston Birth Cohort (n = 7047), multiple logistic regression models were performed to estimate the log odds of either PTB or SGA birth, with paternal involvement, paternal social support, and family and friend social support variables as the primary independent variables. RESULTS About 10% of participating mothers reported their husbands not being involved or supportive during their pregnancies. Lack of paternal involvement was associated with 21% higher risk of PTB (OR = 1.21, 95% CI: 1.01-1.45). Similarly, lack of paternal support was borderline associated with PTB (OR = 1.13, 95% CI: 0.94-1.35). Also marginally significant, lack of paternal involvement (OR = 1.18, 95% CI: 0.95-1.47) and father's support (OR = 1.19, 95% CI: 0.96-1.48) were associated with higher odds of SGA birth. No associations were found between familial and friend support during pregnancy and PTB or SGA. CONCLUSIONS Among predominantly low-income African Americans, lack of paternal involvement and lack of paternal support during pregnancy were associated with an increased risk of PTB, and suggestive of SGA birth. These findings, if confirmed in future research, underscore the important role a father can play in reducing PTB and/or SGA.

Abstract
In 2011, the American Academy of Pediatrics (AAP) published a technical report on the lifelong effects of early toxic stress on human development, and included a new framework for promoting pediatric health: the Ecobiodevelopmental Framework for Early Childhood Policies and Programs. We believe that hospitalization is a specific form of toxic stress for the neonatal patient, and that toxic stress must be addressed by the nursing profession in order to substantially improve outcomes for the critically ill neonate. Approximately 4% of normal birthweight newborns and 85% of low birthweight newborns are hospitalized each year in the highly technological neonatal intensive care unit (NICU). Neonates are exposed to roughly 70 stressful procedures a day during hospitalization, which can permanently and negatively alter the infant's developing brain. Neurologic deficits can be partly attributed to the frequent, toxic, and cumulative exposure to stressors during NICU hospitalization. However, the AAP report does not provide specific action steps necessary to address toxic stress in the NICU and realize the new vision for pediatric health care outlined therein. Therefore, this paper applies the concepts and vision laid out in the AAP report to the care of the hospitalized neonate and provides action steps for true transformative change in neonatal intensive care. We review how the environment of the NICU is a significant source of toxic stress for hospitalized infants. We provide recommendations for caregiving practices that could significantly buffer the toxic stress experienced by hospitalized infants. We also identify areas of research inquiry that are needed to address gaps in nursing knowledge and to propel nursing science forward. Finally, we advocate for several public policies that are not fully addressed in the AAP technical report, but are vital to the health and development of all newborns.

Operational efficiency, patient composition and regional context of U.S. health centers: Associations with access to early prenatal care and low birth weight. Soc Sci Med 2019; 226:143-152.

Abstract
Community health centers (CHCs) provide comprehensive medical services to medically under-served Americans, helping to reduce health disparities. This study aimed to identify the unique compositions and contexts of CHCs to better understand variation in access to early prenatal care and rates of low birth weights (LBW). Data include CHC-level data from the Uniform Data System, and regional-level data from the US Census American Community Survey and Behavioral Risk Factor Surveillance System. First, latent class analysis was conducted to identify unobserved subgroups of CHCs. Second, data envelopment analysis was performed to evaluate the operational efficiency of CHCs. Third, we used generalized linear models to examine the associations between the CHC subgroups, efficiency, and perinatal outcomes. Seven classes of CHCs were identified, including two rural classes, one suburban, one with large centers serving poor minorities in low poverty areas, and three urban classes. Many of these classes were characterized by the racial compositions of their patients. Findings indicate that CHCs serving white patients in rural areas have greater access to early prenatal care. Health centers with greater efficiency have lower rates of LBW, as do those who serve largely white patient populations in rural areas. CHCs serving poor racial minorities living in low-poverty areas had particularly low levels of access to early prenatal care and high rates of LBW. Findings highlight that significant diversity exists in the sociodemographic composition and regional context of US health centers, in ways that are associated with their operations, delivery of care, and health outcomes. Results from this study highlight that while the provision of early prenatal care and the efficiency with which a health center operates may improve the health of the women served by CHCs and their babies, the underlying social and economic conditions facing patients ultimately have a larger association with their health.

Abstract
BACKGROUND Area-level deprivation is associated with multiple adverse birth outcomes. Few studies have examined the mediating pathways through which area-level deprivation affects these outcomes. The objective of this study was to investigate the association between area-level deprivation and preterm birth, and examine the mediating effects of maternal medical, behavioural, and psychosocial factors. METHODS We conducted a retrospective cohort study using national, commercial health insurance claims data from 2011, obtained from the Health Care Cost Institute. Area-level deprivation was derived from principal components methods using ZIP code-level data. Multilevel structural equation modeling was used to examine mediating effects. RESULTS In total, 138,487 women with a live singleton birth residing in 14,577 ZIP codes throughout the United States were included. Overall, 5.7% of women had a preterm birth. In fully adjusted generalized estimation equation models, compared to women in the lowest quartile of area-level deprivation, odds of preterm birth increased by 9.6% among women in the second highest quartile (odds ratio (OR) 1.096; 95% confidence interval (CI) 1.021, 1.176), by 11.3% in the third highest quartile (OR 1.113; 95% CI 1.035, 1.195), and by 24.9% in the highest quartile (OR 1.249; 95% CI 1.165, 1.339). Hypertension and infection moderately mediated this association. CONCLUSIONS Even among commercially-insured women, area-level deprivation was associated with increased risk of preterm birth. Similar to individual socioeconomic status, area-level deprivation does not have a threshold effect. Implementation of policies to reduce area-level deprivation, and the screening and treatment of maternal mediators may be associated with a lower risk of preterm birth.

Abstract
OBJECTIVE This study developed and internally validated a predictive model for preterm birth (PTB) to examine the ability of neighbourhood socioeconomic status (SES) to predict PTB. DESIGN Cohort study using individual-level data from two community-based prospective pregnancy cohort studies (All Our Families (AOF) and Alberta Pregnancy Outcomes and Nutrition (APrON)) and neighbourhood SES data from the 2011 Canadian census. SETTING Calgary, Alberta, Canada. PARTICIPANTS Pregnant women who were <24 weeks of gestation and >15 years old were enrolled in the cohort studies between 2008 and 2012. Overall, 5297 women participated in at least one of these cohorts: 3341 women participated in the AOF study, 2187 women participated in the APrON study and 231 women participated in both studies. Women who participated in both studies were only counted once. PRIMARY AND SECONDARY OUTCOME MEASURES PTB (delivery prior to 37 weeks of gestation). RESULTS The rates of PTB in the least and most deprived neighbourhoods were 7.54% and 10.64%, respectively. Neighbourhood variation in PTB was 0.20, with an intra-class correlation of 5.72%. Neighbourhood SES, combined with individual-level predictors, predicted PTB with an area under the receiver-operating characteristic curve (AUC) of 0.75. The sensitivity was 91.80% at a low-risk threshold, with a high false-positive rate (71.50%), and the sensitivity was 5.70% at a highest risk threshold, with a low false-positive rate (0.90%). An agreement between the predicted and observed PTB demonstrated modest model calibration. Individual-level predictors alone predicted PTB with an AUC of 0.60. CONCLUSION Although neighbourhood SES combined with individual-level predictors improved the overall prediction of PTB compared with individual-level predictors alone, the detection rate was insufficient for application in clinical or public health practice. A prediction model with better predictive ability is required to effectively find women at high risk of preterm delivery.

Abstract
We aimed to clarify how maternal physical characteristics explains the association between adolescent pregnancy and adverse birth outcomes, focusing on their height. We used a national multicenter-based delivery registry among 30,831 women under age 25 years with a singleton pregnancy between 2005 and 2011. Adolescent pregnancy was defined as younger than 20 years of age, and categorized into “junior adolescent” (aged ≤15 years) and “senior adolescent” (aged 16–19 years). We used multivariate Poisson regression and mediation analysis to assess the extent to which maternal height explained the association between adolescent pregnancy and risk of adverse birth outcomes. Risks for preterm birth [(adjusted risk ratio (aRR) 1.17, 95% confidence interval (95% CI), 1.08–1.27], low birthweight (aRR 1.08, 95% CI, 1.01–1.15), and low Apgar score (aRR 1.41 95%CI, 1.15–1.73) were significantly higher among adolescent women compared to women of 20–24 years of age. The mediation effect of maternal height on these outcomes were moderate for low birthweight (45.5%) and preterm birth (10.5%), and smaller for low Apgar score (6.6%). In all analyses, we did not detect significant differences between junior adolescent and senior adolescent. Adolescent women have higher risk of adverse birth outcomes. This association is partially mediated by shorter maternal height.

Abstract
BACKGROUND Socioeconomic experiences are recognized determinants of health, and recent work has shown that social disadvantages in early life may induce sustained biological changes at molecular level that are detectable later in life. However, the dynamics and persistence of biological embedding of socioeconomic position (SEP) remains vastly unexplored. METHODS Using the data from the ALSPAC birth cohort, we performed epigenome-wide association studies of DNA methylation changes at three life stages (birth, n = 914; childhood at mean age 7.5 years, n = 973; and adolescence at mean age 15.5 years, n = 974), measured using the Illumina HumanMethylation450 Beadchip, in relation to pregnancy SEP indicators (maternal and paternal education and occupation). RESULTS Across the four early life SEP metrics investigated, only maternal education was associated with methylation levels at birth, and four CpGs mapped to SULF1, GLB1L2 and RPUSD1 genes were identified [false discovery rate (FDR)-corrected P-value <0.05]. No epigenetic signature was found associated with maternal education in child samples, but methylation levels at 20 CpG loci were found significantly associated with maternal education in adolescence. Although no overlap was found between the differentially methylated CpG sites at different ages, we identified two CpG sites at birth and during adolescence which are 219 bp apart in the SULF1 gene that encodes an heparan sulphatase involved in modulation of signalling pathways. Using data from an independent birth cohort, the ENVIRONAGE cohort, we were not able to replicate these findings. CONCLUSIONS Taken together, our results suggest that parental SEP, and particularly maternal education, may influence the offspring's methylome at birth and adolescence.

Abstract
Introduction Socio-economic status (SES) is an important determinant of health. Low SES is associated with higher rates of prenatal and post-partum depression, and prenatal and post-partum depression are associated with sub-optimal maternal and infant health. Furthermore, increased negative effects of post-partum depression have been reported in children from low SES backgrounds. Objective To assess whether SES was related to the risk of a medical or psychiatric hospitalization associated with depression (HAWD) and the risk of a HAWD by anti-depressant (AD) use during the years around a birth. Methods This retrospective cohort study used linked birth, hospitalization, prescription and tax-file records of the study cohort. We linked registry data of 243,933 women delivering 348,273 live infants in British Columbia (1999-2009). The outcomes of interest were a HAWD and a HAWD with the associated patient AD use. Ranked area-based measures of equivalised, family disposable income were used to create income deciles, our proxy for SES. Decile-1 represented the lowest income areas, and mothers from Decile-6 (middle-income) were the comparator group. Anti-depressant use was defined as having a prescription for a selective serotonin reuptake inhibitor (SSRI) or other AD during the years around a birth, defined as the period beginning 12 months before conception and ending 12 months after the birth. We analysed by pregnancy using mixed effects logistic regression whilst adjusting for maternal age and parity. Results Compared to mothers from middle-income areas (Decile-6), mothers from low income areas (Decile-1, Decile-2) had increased odds of a HAWD [adjusted OR=1.77 (CI: 1.43, 2.19); adjusted OR=1.56 (CI: 1.26, 1.94)]. Mothers from low income areas with depression and no AD use had even higher odds of a HAWD [adjusted OR=1.83 (CI: 1.33, 2.20); adjusted OR=1.71(CI: 1.33, 2.20)]. Conclusions This study provides preliminary evidence to suggest that barriers to treating depression with ADs in mothers from low income areas during the years around a birth might contribute to their increased risk of a HAWD associated with non-pharmacologically treated depression. Further research is needed to understand the reasons for this increased risk.

Abstract
OBJECTIVE Little is known about how prenatal care influences health outcomes in Canada. The objective of this study was to examine the association of prenatal care utilization with maternal, fetal, and infant outcomes in Manitoba. METHODS This retrospective cohort study conducted at the Manitoba Centre for Health Policy investigated all deliveries of singleton births from 2004-2005 to 2008-2009 (N = 67 076). The proportion of women receiving inadequate, intermediate/adequate, and intensive prenatal care was calculated. Multivariable logistic regression was used to examine the association of inadequate and intensive prenatal care with maternal and fetal-infant health outcomes, health care use, and maternal health-related behaviours. RESULTS The distribution of prenatal care utilization was 11.6% inadequate, 84.4% intermediate/adequate, and 4.0% intensive. After adjusting for sociodemographic factors and maternal health conditions, inadequate prenatal care was associated with increased odds of stillbirth, preterm birth, low birth weight, small for gestational age (SGA), admission to the NICU, postpartum depressive/anxiety disorders, and short interpregnancy interval to next birth. Women with inadequate prenatal care had reduced odds of initiating breastfeeding or having their infant immunized. Intensive prenatal care was associated with reduced odds of stillbirth, preterm birth, and low birth weight and increased odds of postpartum depressive/anxiety disorders, initiation of breastfeeding, and infant immunization. CONCLUSION Inadequate prenatal care was associated with increased odds of several adverse pregnancy outcomes and lower likelihood of health-related behaviours, whereas intensive prenatal care was associated with reduced odds of some adverse pregnancy outcomes and higher likelihood of health-related behaviours. Ensuring women receive adequate prenatal care may improve pregnancy outcomes.

Abstract
Introduction Poverty is a well-known risk factor for a child’s health and development. This paper aimed to establish whether poverty negatively affected both intra-uterine growth and early childhood growth, i.e., whether children facing poverty were at a double disadvantage. Methods For this study, we made use of routinely collected data on child development throughout early childhood from the 2006–2009 birth cohorts in Kind & Gezin’s Ikaros database collected during 2,605,975 consultations with 273,935 children from birth to 730 days old. Indicators for child development at birth were gestational age and height-at-birth. A standardized height-for-age indicator captured height development throughout early childhood. A multidimensional indicator measured the risk of poverty. For the analysis of development at birth, we used linear and logistic regression; for the analysis of height development during early childhood, we estimated linear and logistic growth curve models. Results The risk of poverty negatively affected both gestational age and height-at-birth. Throughout early childhood, we observed a negative relation between the risk of poverty and height-for-age indicators. However, the effect varied throughout childhood. Children at risk of poverty (over)compensated for their smaller stature at birth, and between ages 6 and 18 months, approximately, the negative effects of risk of poverty decreased substantially or disappeared. However, towards the end of the period studied, children born in households at risk of poverty started to lag again in height development. Conclusion This study found that the risk of poverty indeed negatively affected a child’s growth, both in utero and in early childhood. However, the results suggest that developmental lags later in childhood were not merely an extension of such lags at birth.

Abstract
BACKGROUND Previous studies have demonstrated that short interpregnancy interval (the interval between delivery and estimated last menstrual period of a subsequent pregnancy) is associated with small for gestational age birth. It is controversial if this association is causal, as few studies have accounted for likely confounding factors such as unintended pregnancy. We examined the association between interpregnancy interval and infant birthweight, adjusting for pregnancy intention and other socio-economic and obstetrical risk factors. METHODS We used data from the Scandinavian Successive Small-for-Gestational-Age births study (1986-1988). Birthweight was expressed as a gestational age-standardised z-score. RESULTS Among 1406 women, a trend towards lower birthweight z-score with short interpregnancy interval was not statistically significant (unadjusted difference in birthweight z-score of -0.25, 95% confidence interval (CI) -0.55, 0.05). After adjusting for pregnancy intention, detailed measures of socio-economic status, and other covariates, the estimated magnitude of effect between interpregnancy interval and birthweight z-score was further attenuated (adjusted difference in birthweight z-score of -0.13, 95% CI -0.46, 0.20). CONCLUSIONS In this cohort study with detailed information on pregnancy intention and socio-economic status, short interpregnancy interval was not associated with lower birthweight. These findings suggest that previously observed associations between short interpregnancy interval and lower birthweight may reflect confounding by socio-economic and/or other unmeasured confounders.

Abstract
Stress has adverse effects on health, and prolonged stress exposure is a risk factor for several mental and physical illnesses. 1 Families living in poverty face many stressors created and maintained by economic hardship and unaddressed legal and social needs. Medical-Legal Partnerships (MLPs) aim to improve health and well-being by addressing health-harming legal and social needs of patients. This pilot study examined whether MLP-involved parents perceived themselves as stressed; to what they attributed their stress; and whether they reported a reduction in stress when their MLP cases were closed. The study shows improvements in perceived stress following receipt of MLP interventions.

Abstract
Objective To explore whether the average price of houses per postcode sector [sector house average prices (SHAP)] is related to perinatal outcomes and whether gestational age would be lower and mortality higher in the least expensive areas compared to the most expensive. Methods All neonatal unit admissions at King's College Hospital from 1/1/2012 to 31/12/2016 were reviewed. The SHAP was retrieved from the Land Registry and the population was divided in equal quintiles with quintiles 1 and 5 representing the most and least expensive areas, respectively. Gestational age and birth weight z-score were collected. Mortality was defined as death before discharge from neonatal care. Results Three thousand three hundred and sixty infants were included and divided in quintiles consisting of 672 infants. Gestational age was lower in quintile 5 compared to all other quintiles (adjusted P<0.001). Birthweight z-score was not significantly different between the quintiles. The SHAP was lower in the infants who died before discharge (n=92) compared to the SHAP of the infants who were alive at discharge (n=3268) (P<0.001). Infants of quintile 5 had 6 times higher risk of death before discharge from neonatal care compared to infants of quintile 1. Conclusion Low SHAPs were associated with poorer perinatal outcomes suggesting SHAP could potentially be used in perinatal populations to determine socio-economic status and associated outcomes.

Abstract
Objectives The Healthy Start Program has taken a community-based approach to improving maternal and child health outcomes among underserved populations for 25 years. Although the program has been evaluated in the past, it has not undergone a national evaluation since it was transformed in 2014. The purpose of this study is to present data from an early component of the latest national evaluation-the 2016 National Healthy Start Program Survey, which includes information describing grantees, the risk profile of participants served, and the scope of services offered to meet participant needs. Methods Ninety-five grantees completed the survey, and responses are reported at the aggregate level. Study analyses are descriptive. Results Grantees reported serving a population with a high-risk profile characterized by chronic medical conditions or risk behaviors. Most grantees conduct comprehensive needs/risk assessments for participants upon program entry, yet service delivery strategies were mixed, with some differences found by geographic region. Grantees provide a core set of services to participants, including case management and health promotion/education, and tend to refer participants to community providers for services that are deemed appropriate during individual risk assessments. While most grantees have protocols in place related to these priority services, participants may not have been universally offered all services across sites. Conclusions for Practice Although grantees often highlight their facilitation of service/care coordination with existing resources, findings suggest potential areas on which to focus strategic efforts to ensure that the Healthy Start Program is successfully bridging gaps in access and utilization of services for underserved communities.

Abstract
The microbiome is now considered our 'second genome' with potentially comparable importance to the genome in determining human health. There is, however, a relatively limited understanding of the broader environmental factors, particularly social conditions, that shape variation in human microbial communities. Fulfilling the promise of microbiome research - particularly the microbiome's potential for modification - will require collaboration between biologists and social and population scientists. For life scientists, the plasticity and adaptiveness of the microbiome calls for an agenda to understand the sensitivity of the microbiome to broader social environments already known to be powerful predictors of morbidity and mortality. For social and population scientists, attention to the microbiome may help answer nagging questions about the underlying biological mechanisms that link social conditions to health. We outline key substantive and methodological advances that can be made if collaborations between social and population health scientists and life scientists are strategically pursued.

Abstract
Aims: In Finland, smoking rates in the general population are decreasing due to increased awareness of the adverse effects and tightened tobacco legislation. However, previous studies have shown that smoking in pregnant Finnish women remained as high as in the general Finnish female population at around 15% in 2010. Our aim was to describe temporal and spatial trends in smoking behaviour, and determinants of changes in smoking behaviour between first and second pregnancy. Methods: Self-reported smoking from the Finnish Medical Birth Register covered the years 1991-2015 (N=1,435,009). The association of maternal age and socioeconomic status with smoking rate was analysed. Spatial trends were assessed at municipality level. Results: The overall smoking rate during early pregnancy remained fairly stable at around 15% from 1991 to 2015, but increased in teenage and young women below 25 years of age. The mean smoking rate (36%) was higher in these age groups than in older pregnant women (11%). Through the study period the smoking rate remained higher in blue collar workers compared with higher socioeconomic groups. Between the first and second child, on average only 4% of women started to smoke and 41% quitted. Smoking rates developed less favourably in Eastern Finland. Conclusions: The observed increase in smoking rate during pregnancy in teenage and young women is concerning. Pregnancy is a trigger point for smoking cessation in a big fraction of pregnant women. More studies are needed to explain the opposite trends of smoking rates in Northern and Western Finland compared with Eastern Finland.

Abstract
BACKGROUND The publication of the World Health Organization (WHO) recommendations on antenatal care in 2016 introduced the perspective of women as a necessary component of clinical guidelines in maternity care. WHO highlights the crucial role played by evidence-based recommendations in promoting and supporting normal birth processes and a positive experience of pregnancy. This paper aims to explore and critically appraise recommendations of national antenatal care guidelines across European countries in comparison with the WHO guideline. METHODS We collected guidelines from country partners of the EU COST Action IS1405. Components of the documents structure and main recommendations within and between them were compared and contrasted with the WHO guideline on antenatal care with a particular interest in exploring whether and how women's experience was included in the recommendations. RESULTS Eight out of eleven countries had a single national guideline on antenatal care while three countries did not. National guidelines mostly focused on care of healthy women with a straightforward pregnancy. The level of concordance between the national and the WHO recommendations varied along a continuum from almost total concordance to almost total dissonance. Women's views and experiences were accounted for in some guidelines, but mostly not placed at the same level of importance as clinical items. CONCLUSIONS Findings outline convergences and divergences with the WHO recommendations. They highlight the need for considering women's views more in the development of evidence-based recommendations and in practice for positive impacts on perinatal health at a global level, and on the experiences of each family.

Abstract
OBJECTIVE Observed associations between maternal prenatal stress and children's socioemotional development have varied widely in the literature. The objective of the current study was to provide a synthesis of studies examining maternal prenatal anxiety and depression and the socioemotional development of their children. METHOD Eligible studies through to February 2018 were identified using a comprehensive search strategy. Included studies examined the association between maternal prenatal depression or anxiety and the future development of their children's socioemotional development (eg, difficult temperament, behavioral dysregulation) up to 18 years later. Two independent coders extracted all relevant data. Random-effects meta-analyses were used to derive mean effect sizes and test for potential moderators. RESULTS A total of 71 studies met full inclusion criteria for data analysis. The weighted average effect size for the association between prenatal stress and child socioemotional problems was as follows: odds ratio (OR) = 1.66 (95% CI = 1.54-1.79). Effect sizes were stronger for depression (OR = 1.79; 95% CI = 1.61-1.99) compared to anxiety (OR = 1.50; 95% CI = 1.36-1.64). Moderator analyses indicated that effect sizes were stronger when depression was more severe and when socio-demographic risk was heightened. CONCLUSION Findings suggest that maternal prenatal stress is associated with offspring socioemotional development, with the effect size for prenatal depression being more robust than for anxiety. Mitigating stress and mental health difficulties in mothers during pregnancy may be an effective strategy for reducing offspring behavioral difficulties, especially in groups with social disadvantage and greater severity of mental health difficulties.

Abstract
Objectives. To identify evidence that income, education, or ethnicity might be associated with low birthweight, small-for-gestational-age birth, or preterm birth. Methods. A systematic review was conducted using searches in two online databases, PubMed and Literature in the Health Sciences in Latin America and the Caribbean (LILACS). The searches covered materials published between 1 January 1982 and 5 May 2016. The search terms used were (“infant, premature” OR “infant, small for gestational age” OR “fetal growth retardation”) AND (“socioeconomic factors” OR “ethnic groups” OR “maternal age”). Results. A total of 3 070 references that met the initial selection criteria were analyzed, and 157 relevant studies were fully read. We located 18 studies that investigated associations of family or maternal income, education, or ethnicity with low birthweight, small-for-gestational-age birth, or preterm birth. Of the 18, 10 of them involved high-income countries, and 8 dealt with middle- or low-income countries. Greater evidence was found for an association between ethnicity and the three outcomes studied, particularly for prematurity among children of black mothers. There was little evidence for an association between maternal/family income or education and any of the three outcomes. Conclusions. Income and education weren't determinants for low birthweight, small-for-gestational-age birth, or preterm birth. However, black ethnicity was strongly associated with the three outcomes, especially with prematurity.

Abstract
The portion of newborns delivered before term is considerably higher in the United States than in other developed countries. We compare the array of risk exposures and protective factors common to women across national settings, using national, regional, and international databases, review articles, and research reports. We find that U.S. women have higher rates of obesity, heart disease, and poor health status than women in other countries. This is in part because more U.S. women are exposed to the stresses of racism and income disparity than women in other national settings, and stress loads are known to disrupt physiological functions. Pregnant women in the United States are not at higher risk for preterm birth because of older maternal age or engagement in high-risk behaviors. However, to a greater extent than in other national settings, they are younger and their pregnancies are unintended. Higher rates of multiple gestation pregnancies, possibly related to assisted reproduction, are also a factor in higher preterm birth rates. Reproductive policies that support intentional childbearing and social welfare policies that reduce the stress of income insecurity can be modeled from those in place in other national settings to address at least some of the elevated U.S. preterm birth rate.

Abstract
INTRODUCTION Hospital utilization varies across socioeconomic and demographic strata in Canada, a country with a universal health care system. Rates of adverse birth outcomes are known to differ among women of high and low socioeconomic status (SES), but less is known of the excess hospital burden related to SES over the course of childbirth across Canadian provinces. OBJECTIVE To examine length of stay and risk of hospitalization surrounding delivery, relative to women's socio-demographic characteristics. METHODS A population-based record linkage between the Canadian Community Health Survey (CCHS) years 2005-2011 and the Discharge Abstract Database (DAD) allowed the tracking of hospital utilization for linked survey respondents between 2005 and 2011. Hourly length of stay for delivery, risk of readmission, and risk of admission prior to delivery was modeled by socio-demographic factors, controlling for other clinical and individual-level characteristics. RESULTS There were 21,914 complete delivery records from 15,458 female CCHS respondents who agreed to link and share their information. Average length of stay (for both vaginal and Caesarian deliveries) dropped over the study period from 67.86 hours in 2005 to 59.37 hours in 2011. In multivariate analyses, women with the lowest income had on average, two-hour longer stays for vaginal delivery as compared to high-income women (IRR 1.04, 95% CI 1.00-1.08) and higher risk of admission prior to delivery (OR 1.43, CI 1.13-1.81). Low-income women, Aboriginal women and women living in rural areas were also at elevated risk for longer hospital stays and for hospital admission prior to delivery. There was no consistent socioeconomic patterning of hospital burden for Caesarian deliveries. CONCLUSION The length of hospital stays for childbirth has declined in Canada. Length of stay remains modestly longer, and risk of hospitalization in the perinatal period higher, for low income women, Aboriginal women and rural women. The absence of egregious income-related differences in hospital burden related to childbirth is reassuring for the equity goals of the Canadian health care system. The persistence of marginally longer, and in turn, costlier visits for low-income and Aboriginal women before and during delivery is, however, suggestive that resources targeted to the prenatal period might be highly cost-effective if they achieve population-wide reductions in length of stay and hospitalization in the perinatal period.

Abstract
BACKGROUND Methodologic challenges related to the concomitant use (co-use) of substances and changes in policy and potency of marijuana contribute to ongoing uncertainty about risks to fetal neurodevelopment associated with prenatal marijuana use. In this study, we examined two biomarkers of fetal neurodevelopmental risk-birth weight and length of gestation-associated with prenatal marijuana use, independent of tobacco (TOB), alcohol (ALC), other drug use (OTH), and socioeconomic risk (SES), in a pooled sample (N = 1191) derived from 3 recent developmental cohorts (2003-2015) with state-of-the-art substance use measures. We examined differential associations by infant sex, and multiplicative effects associated with co-use of MJ and TOB. METHODS Participants were mother-infant dyads with complete data on all study variables derived from Growing Up Healthy (n = 251), Behavior and Mood in Babies and Mothers (Cohorts 1 and 2; n = 315), and the Early Growth and Development Study (N = 625). We estimated direct effects on birth weight and length of gestation associated with MJ, TOB, and co-use (MJ x TOB), using linear regression analysis in the full sample, and in male (n = 654) and female (n = 537) infants, separately. RESULTS Mean birth weight and length of gestation were 3277 g (SD = 543) and 37.8 weeks (SD = 2.0), respectively. Rates of prenatal use were as follows: any use, n = 748 (62.8%); MJ use, n = 273 (22.9%); TOB use, n = 608 (51.0%); co-use of MJ and TOB, n = 230 (19.3%); ALC use, n = 464 (39.0%); and OTH use n = 115 (9.7%.) For all infants, unique effects on birth weight were observed for any MJ use [B(SE) = -84.367(38.271), 95% C.I. -159.453 to -9.281, p = .028], any TOB use [B(SE) = -0.99.416(34.418), 95% C.I. -166.942 to -31.889, p = .004], and each cigarette/day in mean TOB use [B(SE) = -12.233(3.427), 95% C.I. -18.995 to -5.510, p < .001]. Additional effects of co-use on birth weight, beyond these drug-specific effects, were not supported. In analyses stratified by sex, while TOB use was associated with lower birth weight in both sexes, MJ use during pregnancy was associated with lower birth weight of male infants [B(SE) = -153.1 (54.20); 95% C.I. -259.5 to -46.7, p = .005], but not female infants [B(SE) = 8.3(53.1), 95% C.I. -96.024 to 112.551, p = .876]. TOB, MJ, and their co-use were not associated with length of gestation. CONCLUSIONS In this sample, intrauterine co-exposure to MJ and TOB was associated with an estimated 18% reduction in birth weight not attributable to earlier delivery, exposure to ALC or OTH drugs, nor to maternal SES. We found evidence for greater susceptibility of male fetuses to any prenatal MJ exposure. Examination of dose-dependence in relationships found in this study, using continuous measures of exposure, is an important next step. Finally, we underscore the need to consider (a) the potential moderating influence of fetal sex on exposure-related neurodevelopmental risks; and (b) the importance of quantifying expressions of risk through subtle alterations, rather than dichotomous outcomes.

Abstract
OBJECTIVES Evidence about the relationship between socioeconomic status (SES) and small-for-gestational-age (SGA) infants was insufficient among Chinese primiparae. In addition, factors that may mediate this relationship are poorly understood. The purpose of this study was to investigate the risk of and mediators between SES and SGA. DESIGN Retrospective cohort study. SETTING Wuhan, Hubei, China. METHOD Participants were recruited from patients who gave birth in the maternity care hospital of Wuhan between September 2012 and October 2014. Logistic regression models were used to estimate the association between SES and SGA. Pathway analysis was performed to examine the contribution of maternal lifestyles and pregnancy-induced hypertension syndrome (PIH) to the relationship between SES and SGA. Total effect, direct effect and indirect effect of SES on SGA were measured. Effect sizes were evaluated by unstandardised estimates (B) and standardised estimates (ß). RESULTS Among 8737 primiparae, 927 (10.61%) pregnant women had babies with SGA. High SES was inversely associated with risk of SGA (OR 0.856; 95% CI 0.737 to 0.995) after adjustment for potential confounders. Maternal obstetric characteristics, lifestyles and PIH completely mediated SES and SGA (indirect effect: B=-0.067, 95% CI -0.108 to -0.026). The indirect effect of SES was strengthened by PIH (B=-0.029), a multivitamin supplement (B=-0.021), prepregnancy body mass index (BMI) ≥18.50 (B=-0.009) and prepregnancy BMI ≥18.50 to gestational weight gain (GWG) not below the Institute of Medicine (IOM) recommendations (B=-0.003). CONCLUSIONS Women from high SES predicted lower risk of PIH, more chances to take a multivitamin supplement during early pregnancy, keeping prepregnancy BMI ≥18.50 kg/cm2 and gaining adequate gestational weight which was not below IOM recommendations. Furthermore, lower risk of PIH, more chances to take a multivitamin supplement, prepregnancy BMI ≥18.50 kg/cm2 and GWG not below IOM recommendations were associated with a lower risk of SGA infants.

Abstract
Existing research on neighborhood environment and gestational weight gain (GWG) focuses on point-in-time measures of neighborhood context. This precludes understanding how long-term exposure to adverse neighborhood environments influences GWG. We estimated associations between average exposure to and trajectories of long-term neighborhood socioeconomic deprivation and risk of inadequate or excessive GWG. Using data from 5690 full-term, singleton pregnancies in the 1979 National Longitudinal Survey of Youth, we estimated associations between cumulative deprivation and GWG, overall and by race/ethnicity, controlling for individual and residential covariates. A one standard deviation unit (8-point) increase in neighborhood deprivation increased risk of inadequate GWG (Relative Risk (RR): 1.08; 95% Confidence Interval (CI): 1.00-1.16) for all women and excessive GWG (RR: 1.11; 95% CI 1.02-1.21) for white women. Persistent low deprivation (RR: 0.78; 95% CI: 0.64-0.94) and upward mobility (RR: 0.76; 95% CI: 0.61-0.96), compared to persistent high deprivation, reduced risk of inadequate GWG. Persistent low deprivation also reduced risk of excessive GWG (RR: 0.84; 95% CI: 0.71-0.98). Long-term neighborhood deprivation contributes to patterns of GWG over women's life course.
