Understanding country-specific determinants of stillbirth using household surveys: The case of Afghanistan.

Paediatr Perinat Epidemiol 2019 01;33(1):28-44

Sydney School of Public Health, Faculty of Medicine and Health, The University of Sydney, Sydney, New South Wales, Australia.

Background: Stillbirth rates in Afghanistan have declined little in the past decade with no data available on key risk factors. Health care utilisation and maternal complications are important factors influencing pregnancy outcomes but rarely captured for stillbirth in national surveys from low- and middle-income countries. The 2010 Afghanistan Mortality Survey (AMS) is one of few surveys with this information. Read More

Economic conditions during pregnancy and preterm birth: A maternal fixed-effects analysis.

Paediatr Perinat Epidemiol 2019 Jan 24. Epub 2019 Jan 24.

Centers for Epidemiology and Environmental Health, School of Public Health, Brown University, Providence, Rhode Island.

Background: Making causal inference regarding impacts of macrolevel economic conditions during pregnancy on pregnancy outcomes is hampered by the presence of unmeasured variables that may influence women's probability of giving birth under certain economic conditions (ie, exposure) as well as her pregnancy outcomes. Maternal fixed-effects (FE) analyses, in which the association between exposure and outcomes is estimated within mothers who had discordant outcomes, can control for such unmeasured variables when they are invariant across pregnancies.

Methods: We utilised a maternally linked data set of all singleton births in Michigan from 1990 to 2012 (n = 2 657 272 for full sample; n = 269 943 for FE analytic sample) to examine the relationship between state-level unemployment rates during pregnancy and preterm birth (PTB, <37 weeks' gestation).

Towards a unified perinatal theory: Reconciling the births-based and fetus-at-risk models of perinatal mortality.

Authors:
K S Joseph

Paediatr Perinat Epidemiol 2019 Jan 22. Epub 2019 Jan 22.

Department of Obstetrics and Gynaecology, School of Population and Public Health, University of British Columbia and the Children's and Women's Hospital and Health Centre of British Columbia, Vancouver, British Columbia, Canada.

Background: There is a need to reconcile the opposing perspectives of the births-based and fetuses-at-risk models of perinatal mortality and to formulate a coherent and unified perinatal theory.

Methods: Information on births in the United States from 2004 to 2015 was used to calculate gestational age-specific perinatal death rates for low- and high-risk cohorts. Cubic splines were fitted to the fetuses-at-risk birth and perinatal death rates, and first and second derivatives were estimated. Read More

Neighbourhood assets and early pregnancy cardiometabolic risk factors.

Paediatr Perinat Epidemiol 2019 01 10;33(1):79-87. Epub 2019 Jan 10.

Department of Obstetrics, Gynecology, and Reproductive Sciences, School of Medicine, University of Pittsburgh, Pittsburgh, Pennsylvania.

Background: Prepregnancy cardiometabolic risk factors are associated with increased risks of adverse pregnancy outcomes. Neighbourhood features may reflect prepregnancy exposures that contribute to poor cardiometabolic health before pregnancy and may contribute to racial disparities in pregnancy outcomes.

Methods: Early pregnancy measurements from 1504 women enrolled in the Prenatal Exposures and Preeclampsia Prevention study were linked to a 2000 Census-based measure of neighbourhood socio-economic status and commercial data (food, alcohol, and retail density) during 1997-2001. Read More

Are selection criteria for healthy pregnancies responsible for the gap between fetal growth in the French national Elfe birth cohort and the Intergrowth-21st fetal growth standards?

Paediatr Perinat Epidemiol 2019 01 28;33(1):47-56. Epub 2018 Nov 28.

Paris Descartes University, Paris, France.

Background: The Intergrowth-21st (IG) project proposed prescriptive fetal growth standards for global use based on ultrasound measurements from a multicounty study of low-risk pregnancies selected using strict criteria. We examined whether the IG standards are appropriate for fetal growth monitoring in France and whether potential differences could be due to IG criteria for "healthy" pregnancies.

Method: We analysed data on femur length and abdominal circumference at the second and/or the third recommended ultrasound examination from 14 607 singleton pregnancies from the Elfe national birth cohort. Read More

Diagnosing atopic dermatitis in infancy: Questionnaire reports vs criteria-based assessment.

Paediatr Perinat Epidemiol 2018 11 21;32(6):556-567. Epub 2018 Nov 21.

Department of Medicine, McMaster University, Hamilton, Canada.

Background: Persisting atopic dermatitis (AD) is known to be associated with more serious allergic diseases at later ages; however, making an accurate diagnosis during infancy is challenging. We assessed the diagnostic performance of questionnaire-based AD measures with criteria-based in-person clinical assessments at age 1 year and evaluated the ability of these diagnostic methods to predict asthma, allergic rhinitis and food allergies at age 5 years.

Methods: Data relate to 3014 children participating in the Canadian Healthy Infant Longitudinal Development (CHILD) Study who were directly observed in a clinical assessment by an experienced healthcare professional using the UK Working Party criteria. Read More

Short interpregnancy interval and poor fetal growth: Evaluating the role of pregnancy intention.

Paediatr Perinat Epidemiol 2019 01 16;33(1):O73-O85. Epub 2018 Oct 16.

Department of Obstetrics and Gynaecology, University of British Columbia, Vancouver, British Columbia, Canada.

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. Read More

Good practices for the design, analysis, and interpretation of observational studies on birth spacing and perinatal health outcomes.

Paediatr Perinat Epidemiol 2019 01 12;33(1):O15-O24. Epub 2018 Oct 12.

Office of Population Affairs, Office of the Assistant Secretary for Health, Rockville, Maryland.

Background: Meta-analyses of observational studies have shown that women with a shorter interpregnancy interval (the time from delivery to start of a subsequent pregnancy) are more likely to experience adverse pregnancy outcomes, such as preterm delivery or small for gestational age birth, than women who space their births further apart. However, the studies used to inform these estimates have methodological shortcomings.

Methods: In this commentary, we summarise the discussions of an expert workgroup describing good practices for the design, analysis, and interpretation of observational studies of interpregnancy interval and adverse perinatal health outcomes. Read More

Report of the Office of Population Affairs' expert work group meeting on short birth spacing and adverse pregnancy outcomes: Methodological quality of existing studies and future directions for research.

Paediatr Perinat Epidemiol 2019 01 9;33(1):O5-O14. Epub 2018 Oct 9.

Office of Population Affairs, Office of the Assistant Secretary for Health, Rockville, Maryland.

Background: The World Health Organization (WHO) recommends that women wait at least 24 months after a livebirth before attempting a subsequent pregnancy to reduce the risk of adverse maternal, perinatal, and infant health outcomes. However, the applicability of the WHO recommendations for women in the United States is unclear, as breast feeding, nutrition, maternal age at first birth, and total fertility rate differs substantially between the United States and the low- and middle-resource countries upon which most of the evidence is based.

Methods: To inform guideline development for birth spacing specific to women in the United States, the Office of Population Affairs (OPA) convened an expert work group meeting in Washington, DC, on 14-15 September 2017 among reproductive, perinatal, paediatric, social, and public health epidemiologists; obstetrician-gynaecologists; biostatisticians; and experts in evidence synthesis related to women's health.

Caesarean delivery, childhood asthma, and effect modification by sex: An observational study and meta-analysis.

Paediatr Perinat Epidemiol 2018 11 28;32(6):495-503. Epub 2018 Sep 28.

School of Community Health Sciences, University of Nevada Reno, Reno, Nevada.

Background: Numerous studies indicate caesarean delivery is associated with childhood asthma. Sex-specific associations were reported in four of these studies, and in all four studies, the estimated association between caesarean delivery and asthma was of greater magnitude among girls, although most report a lack of evidence of multiplicative interaction.

Methods: We assessed potential effect modification by sex, on the additive and multiplicative scales, of the association between caesarean delivery and asthma by ages 2 through 6 in up to 17 075 racially diverse children from a retrospective birth cohort, the Kaiser Air Pollution and Pediatric Asthma (KAPPA) Study.

Associations of snoring frequency and intensity in pregnancy with time-to-delivery.

Paediatr Perinat Epidemiol 2018 11 28;32(6):504-511. Epub 2018 Sep 28.

Department of Neurology, Sleep Disorders Center, University of Michigan, Ann Arbor, Michigan.

Background: Sleep-disordered breathing (SDB) is linked to adverse pregnancy outcomes. However, little is known about the association of SDB with timing of delivery. We examined the association of snoring frequency, a key SDB marker, and snoring intensity, a correlate of SDB severity, with time-to-delivery among a cohort of pregnant women. Read More

Vaccine-preventable severe morbidity and mortality caused by meningococcus and pneumococcus: A population-based study in France.

Paediatr Perinat Epidemiol 2018 09 31;32(5):442-447. Epub 2018 Aug 31.

Inserm UMR 1153, Obstetrical, Perinatal and Pediatric Epidemiology Research Team (Epopé), Center for Epidemiology and Statistics Sorbonne Paris Cité (CRESS), Paris Descartes University, Paris, France.

Background: In a context of suboptimal vaccination coverage and increasing vaccine hesitancy, we aimed to study morbidity and mortality in children related to missing or incomplete meningococcal C and pneumococcal conjugate vaccines.

Methods: We conducted a prospective, observational, population-based study from 2009 to 2014 in a French administrative area that included all children from age 1 month to 16 years who died before admission or were admitted to an intensive care unit for a community-onset bacterial infection. Vaccine-preventable infection was defined as an infection with an identified serotype included in the national vaccine schedule at the time of infection and occurring in a non- or incompletely vaccinated child.

Secondhand smoke during the periconceptional period increases the risk for orofacial clefts in offspring.

Paediatr Perinat Epidemiol 2018 09 26;32(5):423-427. Epub 2018 Jul 26.

Institute of Reproductive and Child Health/Key Laboratory of Reproductive Health, National Health Commission of the People's Republic of China, Peking University, Beijing, China.

Background: To examine whether exposure to secondhand smoke (SHS) during the periconceptional period among nonsmoking women is associated with an increased risk for orofacial clefts (OFCs) in offspring in a population with low rates of maternal active smoking but high rates of SHS exposure.

Methods: We recruited 240 women with OFC-affected pregnancies and 1420 women who delivered healthy infants from a population-based case-control study in northern China during 2002 and 2016. Data including self-reported SHS exposure were collected by trained health care workers through face-to-face interviews. Read More

Rotavirus vaccination and short-term risk of adverse events in US infants.

Paediatr Perinat Epidemiol 2018 09 26;32(5):448-457. Epub 2018 Jul 26.

Department of Epidemiology, Gillings School of Global Public Health, University of North Carolina at Chapel Hill, Research Triangle Park, North Carolina.

Background: The aim of this study was to evaluate the short-term risk of adverse events associated with rotavirus vaccine (RV) in infants, overall and by vaccine formulation (three-dose pentavalent, RV5; two-dose monovalent, RV1).

Methods: We identified US newborns with commercial insurance during 2006-2014 receiving a diphtheria-tetanus-pertussis vaccine (DTaP) dose and assessed if RV was administered concurrently. We followed infants for 30 days after each dose for diagnoses of intussusception, other gastrointestinal events, seizures, Kawasaki disease, thrombocytopenia, otitis media, all-cause emergency department visits, and all-cause hospitalisations.

Foetal ultrasound measurement imputations based on growth curves versus multiple imputation chained equation (MICE).

Paediatr Perinat Epidemiol 2018 09 17;32(5):469-473. Epub 2018 Jul 17.

Department of Biostatistics, School of Public Health, University of Michigan, Ann Arbor, MI, USA.

Background: Ultrasound measures are valuable for epidemiologic studies of risk factors for growth restriction. Longitudinal measurements enable investigation of rates of change and identification of windows where growth is impacted more acutely. However, missing data can be problematic in these studies, limiting sample size, ability to characterise windows of vulnerability, and in some instances creating bias. Read More

Life-course neighbourhood opportunity and racial-ethnic disparities in risk of preterm birth.

Paediatr Perinat Epidemiol 2018 09 16;32(5):412-419. Epub 2018 Jul 16.

Environmental Health Investigations Branch, California Department of Public Health, Richmond, CA, USA.

Background: Neighbourhood opportunity, measured by poverty, income and deprivation, has been associated with preterm birth, however little is known about the contribution of early-life and life-course neighbourhood opportunity to preterm birth risk and racial-ethnic disparities. We examined maternal early-life and adult neighbourhood opportunity in relation to risk of preterm birth and racial-ethnic disparities in a population-based cohort of women under age 30.

Methods: We linked census tract poverty data to 2 generations of California births from 1982-2011 for 403 315 white, black, or Latina mothers-infant pairs. Read More

Differences in caesarean rates across women's socio-economic status by diverse obstetric indications: Cross-sectional study.

Paediatr Perinat Epidemiol 2018 07 5;32(4):309-317. Epub 2018 Jul 5.

Department of Community Health Sciences, University of Calgary, Calgary, AB, Canada.

Background: The existing inconsistent association between the caesarean rate and maternal socio-economic status (SES) may be the result of a failure to examine the association across indications for caesarean. This study examined the variation in caesarean rates by maternal SES across diverse obstetric-indications.

Methods: Data on demographics, education, insurance status, medical-conditions, and obstetric characteristics needed to classify deliveries according to Robson's 10 obstetric-groups were extracted from the 2015 US birth certificate data (n = 3 988 733). Read More
