Objective: To examine the association between gestational age at birth across the entire gestational age spectrum and special educational needs (SENs) in UK children at 11 years of age.Methods: The Millennium Cohort Study is a nationally representative longitudinal sample of children born in the UK during 2000-2002. Information about the child's birth, health and sociodemographic factors was collected when children were 9 months old. Information about presence and reasons for SEN was collected from parents at age 11. Adjusted relative risks (aRRs) were estimated using modified Poisson regression, accounting for confounders.Results: The sample included 12 081 children with data at both time points. The overall prevalence of SEN was 11.2%, and it was inversely associated with gestational age. Among children born <32 weeks of gestation, the prevalence of SEN was 27.4%, three times higher than among those born at 40 weeks (aRR=2.89; 95% CI 2.02 to 4.13). Children born early term (37-38 weeks) were also at increased risk for SEN (aRR=1.33; 95% CI 1.11 to 1.59); this was the same when the analysis was restricted to births after labour with spontaneous onset. Birth before full term was more strongly associated with having a formal statement of SEN or SEN for multiple reasons.Conclusion: Children born at earlier gestational ages are more likely to experience SEN, have more complex SEN and require support in multiple facets of learning. This association was observed even among children born early-term and when labour began spontaneously. [ABSTRACT FROM AUTHOR]

Objective: This study describes core outcomes of Hirschsprung's disease (HD) in a UK-wide cohort of primary school-aged children.Design: A prospective cohort study conducted from 1 October 2010 to 30 September 2012. Outcomes data were collected from parents and clinicians when children were 5-8 years of age, and combined with data collected at birth, and 28 days and 1 year post diagnosis.Setting: All 28 UK and Irish paediatric surgical centres.Participants: Children with histologically proven HD diagnosed at <6 months of age.Main Outcome Measures: NETS1HD core outcomes.Results: Data were returned for 239 (78%) of 305 children. Twelve children (5%) died prior to 5 years of age.Of the 227 surviving children, 30 (13%) had a stoma and 21 (9%) were incontinent of urine. Of the 197 children without a stoma, 155 (79%) maintained bowel movements without enemas/washouts, while 124 (63%) reported faecal incontinence. Of the 214 surviving children who had undergone a pull-through operation, 95 (44%) underwent ≥1 unplanned reoperation. 89 unplanned reoperations (27%) were major/complex.Of the 83 children with returned PedsQL scores, 37 (49%) had quality of life scores, and 31 (42%) had psychological well-being scores, that were ≥1 SD lower than the reference population mean for children without HD.Conclusion: This study gives a realistic picture of population outcomes of HD in primary school-aged children in the UK/Ireland. The high rates of faecal incontinence, unplanned procedures and low quality of life scores are sobering. Ensuring clinicians address the bladder, bowel and psychological problems experienced by children should be a priority. [ABSTRACT FROM AUTHOR]

Objectives: To determine the incidence of and risk factors for neonatal unit admission, intrapartum stillbirth or neonatal death without admission, and describe outcomes, in babies born in an alongside midwifery unit (AMU).Design: National population-based case-control study.Method: We used the UK Midwifery Study System to identify and collect data about 1041 women who gave birth in AMUs, March 2017 to February 2018, whose babies were admitted to a neonatal unit or died (cases) and 1984 controls from the same AMUs. We used multivariable logistic regression, generating adjusted OR (aOR) with 95% CIs, to investigate maternal and intrapartum factors associated with neonatal admission or mortality.Results: The incidence of neonatal admission or mortality following birth in an AMU was 1.2%, comprising neonatal admission (1.2%) and mortality (0.01%). White 'other' ethnicity (aOR=1.28; 95% CI=1.01 to 1.63); nulliparity (aOR=2.09; 95% CI=1.78 to 2.45); ≥2 previous pregnancies ≥24 weeks' gestation (aOR=1.38; 95% CI=1.10 to 1.74); male sex (aOR=1.46; 95% CI=1.23 to 1.75); maternal pregnancy problem (aOR=1.40; 95% CI=1.03 to 1.90); prolonged (aOR=1.42; 95% CI=1.01 to 2.01) or unrecorded (aOR=1.38; 95% CI=1.05 to 1.81) second stage duration; opiate use (aOR=1.31; 95% CI=1.02 to 1.68); shoulder dystocia (aOR=5.06; 95% CI=3.00 to 8.52); birth weight <2500 g (aOR=4.12; 95% CI=1.97 to 8.60), 4000-4999 g (aOR=1.64; 95% CI=1.25 to 2.14) and ≥4500 g (aOR=2.10; 95% CI=1.17 to 3.76), were independently associated with neonatal admission or mortality. Among babies admitted (n=1038), 18% received intensive care. Nine babies died, six following neonatal admission. Sepsis (52%) and respiratory distress (42%) were the most common discharge diagnoses.Conclusions: The results of this study are in line with other evidence on risk factors for neonatal admission, and reassuring in terms of the quality and safety of care in AMUs.

Objective: To describe ethnic and socioeconomic variation in cause-specific infant mortality of preterm babies by gestational age at birth.Design: National birth cohort study.Setting: England and Wales 2006-2012.Subjects: Singleton live births at 24-36 completed weeks' gestation (n=256 142).Outcome Measures: Adjusted rate ratios for death in infancy by cause (three groups), within categories of gestational age at birth (24-27, 28-31, 32-36 weeks), by baby's ethnicity (nine groups) or area deprivation score (Index of Multiple Deprivation quintiles).Results: Among 24-27 week births (5% of subjects; 47% of those who died in infancy), all minority ethnic groups had lower risk of immaturity-related death than White British, the lowest rate ratios being 0.63 (95% CI 0.49 to 0.80) for Black Caribbean, 0.74 (0.64 to 0.85) for Black African and 0.75 (0.60 to 0.94) for Indian. Among 32-36 week births, all minority groups had higher risk of death from congenital anomalies than White British, the highest rate ratios being 4.50 (3.78 to 5.37) for Pakistani, 2.89 (2.10 to 3.97) for Bangladeshi and 2.06 (1.59 to 2.68) for Black African; risks of death from congenital anomalies and combined rarer causes (infection, intrapartum conditions, SIDS and unclassified) increased with deprivation, the rate ratios comparing the most with the least deprived quintile being, respectively, 1.54 (1.22 to 1.93) and 2.05 (1.55 to 2.72). There was no evidence of socioeconomic variation in deaths from immaturity-related conditions.Conclusions: Gestation-specific preterm infant mortality shows contrasting ethnic patterns of death from immaturity-related conditions in extremely-preterm babies, and congenital anomalies in moderate/late-preterm babies. Socioeconomic variation derives from congenital anomalies and rarer causes in moderate/late-preterm babies. Future research should examine biological origins of extremely preterm birth.

Objectives: To describe the epidemiology and geographical differences in prevalence of congenital cerebral anomalies in Europe.Design and Setting: Congenital cerebral anomalies (International Classification of Diseases, 10th Revision code Q04) recorded in 29 population-based EUROCAT registries conducting surveillance of 1.7 million births per annum (29% of all European births).Participants: All birth outcomes (live births, fetal deaths from 20 weeks gestation and terminations of pregnancy after prenatal diagnosis of a fetal anomaly (TOPFA)) from 2005 to 2014.Main Outcome Measures: Prevalence, proportion of associated non-cerebral anomalies, prenatal detection rate.Results: 4927 cases with congenital cerebral anomalies were identified; a prevalence (adjusted for under-reporting) of 9.8 (95% CI: 8.5 to 11.2) per 10 000 births. There was a sixfold difference in prevalence across the registries. Registries with higher proportions of prenatal diagnoses had higher prevalence. Overall, 55% of all cases were liveborn, 3% were fetal deaths and 41% resulted in TOPFA. Forty-eight per cent of all cases were an isolated cerebral anomaly, 25% had associated non-cerebral anomalies and 27% were chromosomal or part of a syndrome (genetic or teratogenic). The prevalence excluding genetic or chromosomal conditions increased by 2.4% per annum (95% CI: 1.3% to 3.5%), with the increases occurring only for congenital malformations of the corpus callosum (3.0% per annum) and 'other reduction deformities of the brain' (2.8% per annum).Conclusions: Only half of the cases were isolated cerebral anomalies. Improved prenatal and postnatal diagnosis may account for the increase in prevalence of congenital cerebral anomalies from 2005 to 2014. However, major differences in prevalence remain between regions. [ABSTRACT FROM AUTHOR]

Objective: To report outcomes to 1 year, in infants born with congenital diaphragmatic hernia (CDH), explore factors associated with infant mortality and examine the relationship between surgical techniques and postoperative morbidity.Design: Prospective national population cohort study.Setting: Paediatric surgical centres in the UK and Ireland.Method: Data were collected to 1 year for infants with CDH live-born between 1 April 2009 to 30 September 2010. Factors associated with infant mortality are explored using logistic regression. Postoperative morbidity following patch versus primary closure, minimally invasive versus open surgery and biological versus synthetic patch material is described. Data are presented as n (%) and median (IQR).Results: Overall known survival to 1 year was 75%, 95% CI 68% to 81% (138/184) and postoperative survival 93%, 95% CI 88% to 97% (138/148). Female sex, antenatal diagnosis, use of vasodilators or inotropes, being small for gestational age, patch repair and use of surfactant were all associated with infant death. Infants undergoing patch repair had a high incidence of postoperative chylothorax (11/54 vs 2/96 in infants undergoing primary closure) and a long length of hospital stay (41 days, IQR 24-68 vs 16 days, IQR 10-25 in primary closure group). Infants managed with synthetic patch material had a high incidence of chylothorax (11/34 vs 0/19 with biological patch).Conclusion: The majority of infant deaths in babies born with CDH occur before surgical correction. Female sex, being born small for gestational age, surfactant use, patch repair and receipt of cardiovascular support were associated with a higher risk of death. The optimum surgical approach, timing of operation and choice of patch material to achieve lowest morbidity warrants further evaluation. [ABSTRACT FROM AUTHOR]

Objective: To investigate socioeconomic inequalities in cause-specific stillbirth and neonatal mortality to identify key areas of focus for future intervention strategies to achieve government ambitions to reduce mortality rates.Design: Retrospective cohort study.Setting: England, Wales, Scotland and the UK Crown Dependencies.Participants: All singleton births between 1 January 2014 and 31 December 2015 at ≥24 weeks' gestation.Main Outcome Measure: Cause-specific stillbirth or neonatal death (0-27 days after birth) per 10 000 births by deprivation quintile.Results: Data on 5694 stillbirths (38.1 per 10 000 total births) and 2368 neonatal deaths (15.9 per 10 000 live births) were obtained from Mothers and Babies: Reducing Risk through Audits and Confidential Enquiries across the UK (MBRRACE-UK). Women from the most deprived areas were 1.68 (95% CI 1.56 to 1.81) times more likely to experience a stillbirth and 1.67 (95% CI 1.48 to 1.87) times more likely to experience a neonatal death than those from the least deprived areas, equating to an excess of 690 stillbirths and 231 neonatal deaths per year associated with deprivation. Small for gestational age (SGA) unexplained antepartum stillbirth was the greatest contributor to excess stillbirths accounting for 33% of the deprivation gap in stillbirths. Congenital anomalies accounted for the majority (59%) of the deprivation gap in neonatal deaths, followed by preterm birth not SGA (24-27 weeks, 27%).Conclusions: Cause-specific mortality rates at a national level allow identification of key areas of focus for future intervention strategies to reduce mortality. Despite a reduction in the deprivation gap for stillbirths and neonatal deaths, public health interventions should primarily focus on socioeconomic determinants of SGA stillbirth and congenital anomalies.

Objectives: This study aimed to describe the variation in risks of adverse birth outcomes across ethnic groups and socioeconomic circumstances, and to explore the evidence of mediation by socioeconomic circumstances of the effect of ethnicity on birth outcomes. Setting: England and Wales. Participants: The data came from the 4.6 million singleton live births between 2006 and 2012. Exposure: The main exposure was ethnic group. Socioeconomic circumstances, the hypothesised mediator, were measured using the Index of Multiple Deprivation (IMD), an area-level measure of deprivation, based on the mother's place of residence. Primary and secondary outcome measures: The primary outcomes were birth outcomes, namely: neonatal death, infant death and preterm birth. We estimated the slope and relative indices of inequality to describe differences in birth outcomes across IMD, and the proportion of the variance in birth outcomes across ethnic groups attributable to IMD. We investigated mediation by IMD on birth outcomes across ethnic groups using structural equation modelling. Results: Neonatal mortality, infant mortality and preterm birth risks were 2.1 per 1000, 3.2 per 1000 and 5.6%, respectively. Babies in the most deprived areas had 47%-129% greater risk of adverse birth outcomes than those in the least deprived areas. Minority ethnic babies had 48%-138% greater risk of adverse birth outcomes compared with white British babies. Up to a third of the variance in birth outcomes across ethnic groups was attributable to differences in IMD, and there was strong statistical evidence of an indirect effect through IMD in the effect of ethnicity on birth outcomes. Conclusion: There is evidence that socioeconomic circumstances could be contributing to the differences in birth outcomes across ethnic groups. [ABSTRACT FROM AUTHOR]

Objective: Outcome reporting heterogeneity impedes identification of gold standard treatments for children born with gastroschisis. Use of core outcome sets (COSs) in research reduces outcome reporting heterogeneity and ensures that studies are relevant to patients. The aim of this study was to develop a gastroschisis COS.Design and Setting: Systematic reviews and stakeholder nomination were used to identify candidate outcomes that were subsequently prioritised by key stakeholders in a three-phase online Delphi process and face-to-face consensus meeting using a 9-point Likert scale. In phases two and three of the Delphi process, participants were shown graphical and numerical representations of their own, and all panels scores for each outcome respectively and asked to review their previous score in light of this information. Outcomes were carried forward to the consensus meeting if prioritised by two or three stakeholder panels in the third phase of the Delphi process. The COS was formed from outcomes where ≥70% of consensus meeting participants scored the outcome 7-9 and <15% of participants scored it 1-3.Results: 71 participants (84%) completed all phases of the Delphi process, during which 87 outcomes were assessed. Eight outcomes, mortality, sepsis, growth, number of operations, severe gastrointestinal complication, time on parenteral nutrition, liver disease and quality of life for the child, met criteria for inclusion in the COS.Conclusions: Eight outcomes have been included in the gastroschisis COS as a result of their importance to key stakeholders. Implementing use of the COS will increase the potential for identification of gold standard treatments for the management of children born with gastroschisis. [ABSTRACT FROM AUTHOR]

Objectives: Construct updated birth weight-for-gestational age centile charts for use in the UK and compare these to the currently used UK-WHO charts.Design: Secondary analysis of national birth data.Participants: Centiles were constructed using 1 269 403 singleton births occurring in England and Wales in 2013-2014 as part of the MBRRACE-UK national perinatal surveillance programme. These were then validated using 642 737 singleton births occurring in England and Wales in 2015.Main Outcome Measures: Sex-specific birth weight-for-gestational age centiles. Centiles were created using the lambda-mu-sigma method via the GAMLSS package in R. This method transforms the skewed birth weight distribution to approximate a normal distribution, allowing any birth weight centile to be produced.Results: The new centiles performed well in the validation sample, with the observed and expected proportion of births below a given centile in agreement. Overall, driven by the predominance of term births, the UK-WHO charts classify a smaller proportion of infants as below a given centile. For example, the UK-WHO estimates classified only 1.32% (8035/606 430) of term infants born in 2015 as below the second centile, compared with 1.97% (11 975/606 430) using the new MBRRACE-UK centiles. At the earliest gestational ages, however, the opposite is observed, with the UK-WHO classifying a larger proportion of infants as below a given centile, particularly at the lower end of the birthweight distribution.Conclusions: We have constructed and validated updated birth weight-for-gestational age centiles using a contemporary sample of births occurring in England and Wales. The benefits of these updated centiles will be first to assist the national surveillance of perinatal mortality programme by improving the identification of the proportion of stillbirths and neonatal deaths affected by intrauterine growth restriction and, second, to aid clinicians by more accurately identifying babies who require increased monitoring in the period immediately following birth.

Purpose: This study aims to describe short-term outcomes of live-born infants with congenital diaphragmatic hernia (CDH) and to identify prognostic factors associated with early mortality.Design: A prospective population cohort study was undertaken between April 2009 and September 2010, collecting data on live-born infants with CDH from all 28 paediatric surgical centres in the UK and Ireland using an established surgical surveillance system. Management and outcomes are described. Prognostic factors associated with death before surgery are explored.Results: Two hundred and nineteen live-born infants with CDH were reported within the data collection period. There were 1.5 times more boys than girls (n=133, 61%). Thirty-five infants (16%) died without an operation. This adverse outcome was associated with female sex (adjusted OR (aOR) 3.96, 95% CI 1.66 to 9.47), prenatal diagnosis (aOR 4.99, 95% CI 1.31 to 18.98), and the need for physiological support in the form of inotropes (aOR 9.96, 95% CI 1.19 to 83.25) or pulmonary vasodilators (aOR 4.09, 95% CI 1.53 to 10.93). Significant variation in practice existed among centres, and some therapies potentially detrimental to infant outcomes were used, including pulmonary surfactant in 45 antenatally diagnosed infants (34%). Utilisation of extracorporeal membrane oxygenation was very low compared with published international studies (n=9/219, 4%). Postoperative 30-day survival was 98% for 182 infants with CDH who were adequately physiologically stabilised and underwent surgery.Conclusion: This is the first British Isles population-based study reporting outcome metrics for infants born with CDH. 16% of babies did not survive to undergo surgery. Factors associated with poor outcome included female sex and prenatal diagnosis. Early postoperative survival in those who underwent surgical repair was excellent. [ABSTRACT FROM AUTHOR]

Objective: Neonatal encephalopathy (NE) is the third leading cause of child mortality. Preclinical studies suggest infection and inflammation can sensitise or precondition the newborn brain to injury. This study examined perinatal risks factor for NE in Uganda.Design: Unmatched case-control study.Setting: Mulago National Referral Hospital, Kampala, Uganda.Methods: 210 term infants with NE and 409 unaffected term infants as controls were recruited over 13 months. Data were collected on preconception, antepartum and intrapartum exposures. Blood culture, species-specific bacterial real-time PCR, C reactive protein and placental histology for chorioamnionitis and funisitis identified maternal and early newborn infection and inflammation. Multivariable logistic regression examined associations with NE.Results: Neonatal bacteraemia (adjusted OR (aOR) 8.67 (95% CI 1.51 to 49.74), n=315) and histological funisitis (aOR 11.80 (95% CI 2.19 to 63.45), n=162) but not chorioamnionitis (aOR 3.20 (95% CI 0.66 to 15.52), n=162) were independent risk factors for NE. Among encephalopathic infants, neonatal case fatality was not significantly higher when exposed to early neonatal bacteraemia (OR 1.65 (95% CI 0.62 to 4.39), n=208). Intrapartum antibiotic use did not improve neonatal survival (p=0.826). After regression analysis, other identified perinatal risk factors (n=619) included hypertension in pregnancy (aOR 3.77), male infant (aOR 2.51), non-cephalic presentation (aOR 5.74), lack of fetal monitoring (aOR 2.75), augmentation (aOR 2.23), obstructed labour (aOR 3.8) and an acute intrapartum event (aOR 8.74).Conclusions: Perinatal infection and inflammation are independent risk factors for NE in this low-resource setting, supporting a role in the aetiological pathway of term brain injury. Intrapartum antibiotic administration did not mitigate against adverse outcomes. The importance of intrapartum risk factors in this sub-Saharan African setting is highlighted. [ABSTRACT FROM AUTHOR]

Objective: To determine the trajectory of cognitive test scores from infancy to adulthood in individuals born extremely preterm compared with term-born individuals.Design: A prospective, population-based cohort study.Setting: 276 maternity units in the UK and Ireland.Patients: 315 surviving infants born less than 26 completed weeks of gestation recruited at birth in 1995 and 160 term-born classroom controls recruited at age 6.Main Outcome Measures: Bayley Scales of Infant Development-Second Edition (age 2.5); Kaufman Assessment Battery for Children (ages 6/11); Wechsler Abbreviated Scale of Intelligence-Second Edition (age 19).Results: The mean cognitive scores of extremely preterm individuals over the period were on average 25.2 points below their term-born peers (95% CI -27.8 to -22.6) and remained significantly lower at every assessment. Cognitive trajectories in term-born boys and girls did not differ significantly, but the scores of extremely preterm boys were on average 8.8 points below those of extremely preterm girls (95% CI -13.6 to -4.0). Higher maternal education elevated scores in both groups by 3.2 points (95% CI 0.8 to 5.7). Within the extremely preterm group, moderate/severe neonatal brain injury (mean difference: -10.9, 95% CI -15.5 to -6.3) and gestational age less than 25 weeks (mean difference: -4.4, 95% CI -8.4 to -0.4) also had an adverse impact on cognitive function.Conclusions: There is no evidence that impaired cognitive function in extremely preterm individuals materially recovers or deteriorates from infancy through to 19 years. Cognitive test scores in infancy and early childhood reflect early adult outcomes. [ABSTRACT FROM AUTHOR]

Objective: The objective of this study was to develop a Hirschsprung's disease (HD) core outcome set (COS).Methods: Candidate outcomes were identified from a systematic review and stakeholder nomination. A three-phase Delphi process and consensus meeting were used to prioritise candidate outcomes based on scores assigned by stakeholder participants using a nine-point scale. In phases two and three, participants were shown graphical representations of their panel's scores and all panels' scores respectively for each outcome from the previous phase. After the third phase, outcomes prioritised by two or three panels were taken forward to the consensus meeting. The COS was formed from the 10 highest scoring outcomes meeting the threshold for inclusion (≥70% 7-9 and <15% 1-3).Results: Eighty-nine stakeholders (82%) completed all three phases of the Delphi process. Seventy-four outcomes were assessed in phase one of the Delphi process, the following 10 of which met criteria for inclusion in the COS: (1) death with cause specified, (2) long-term faecal incontinence, (3) long-term voluntary bowel movements without need for enemas, or rectal or colonic irrigation, (4) long-term psychological stress for the individual with Hirschsprung's disease, (5) long-term urinary incontinence, (6) objective score of quality of life, (7) objective score of bowel function, (8) unplanned reoperation, (9) >need for a permanent stoma, (10) enterocolitis.Conclusions: This HD COS is formed of 10 outcomes deemed important by key stakeholders. Use of this COS in research will reduce outcome reporting heterogeneity and increase our ability to identify gold standard treatments for HD. [ABSTRACT FROM AUTHOR]

Objectives: The aim of this analysis was to quantify the risk factors associated with maternal morbidity among women in Victoria, Australia, focusing particularly on sociodemographic factors. Design: Case–control analysis. Participants: Data on all maternities in Victoria from 1 January 2006 to 31 December 2008. Methods: A case–control analysis was conducted using unconditional logistic regression to calculate adjusted ORs (aORs). Cases were defined as all women noted to have had a severe complication during the index pregnancy. Severe maternal morbidity was defined by the validated, composite Australian Maternal Morbidity Outcome Indicator. Socioeconomic position was defined by Socio-Economic Indices for Areas (SEIFA), specifically the Index of Relative Socioeconomic Disadvantage (IRSD), and other variables analysed were age, parity, Indigenous background, multiple pregnancy, country of birth, coexisting medical condition, previous caesarean section, spontaneous abortion or ectopic pregnancy. Results: The study population comprised 211 060 women, including 1119 cases of severe maternal morbidity (0.53%). Compared with the highest IRSD quintile, the aOR for the 2nd quintile was 1.23 (95% CI 1.03 to 1.49), 0.98 (95% CI 0.79 to 1.21) for the 3rd quintile, 1.55 (95% CI 1.28 to 1.87) for the 4th and 1.21 (95% CI 1.00 to 1.47) for the lowest (most deprived) quintile. Indigenous status was associated with twice (aOR 2.02; 95% CI 1.32 to 3.09) the odds of being a case. Other risk factors for severe maternal morbidity were age ≥35 years (aOR 1.22; 95% CI 1.04 to 1.44), coexisting medical condition (aOR 1.39; 95% CI 1.16 to 1.65), multiple pregnancy (aOR 2.30; 95% CI 1.71 to 3.10), primiparity (aOR 1.36; 95% CI 1.18 to 1.57), previous caesarean section (aOR 1.79; 95% CI 1.53 to 2.10) and previous spontaneous miscarriage (aOR 1.25; 95% CI 1.08 to 1.44). Conclusions: The findings from Victoria strongly suggest that social disadvantage needs to be acknowledged and further investigated as an independent risk factor for adverse maternal outcomes in Australia and incorporated into appropriate policy planning and healthcare programmes.

Objective: To explore the association between maternal disability as measured by the presence of a limiting longstanding illness (LLI) 9 months postpartum and subsequent child health at the age of 7 years. Design: Nationally representative prospective longitudinal study. Setting: England, Scotland, Wales and Northern Ireland. Participants: Secondary analysis of data on 11 807 mother-child pairs recruited to the UK Millennium Cohort Study. Baseline interviews with mothers were carried out in 2001-2002. When the children were 7 years old, the follow-up survey included questions about limiting longstanding health conditions in the child. Primary outcome measure: Any longstanding condition that was reported to limit the children's activities in any way. Results: Nearly 7% of all children were reported to have an LLI at the age of 7 years. The majority (88.1%, 95% CI 85.6% to 90.2%) of children whose mother was disabled did not have an LLI themselves. The children of disabled mothers, however, had higher odds of LLI (OR=1.9, 95% CI 1.5 to 2.5) independently of different maternal, pregnancy and birth characteristics and breast feeding duration. Inclusion of poverty measures in the model did not significantly affect the odds (OR=1.8, 95% CI 1.4 to 2.4), suggesting that maternal LLI around the time of birth increases the odds of child LLI at the age of 7 years independently of starting life in poverty. Conclusions: There is a strong positive association between maternal and child LLI. Health professionals should work together with social care and other relevant service providers to identify the individual needs of disabled parents and provide adequate support throughout the pregnancy and after the child is born. Further research is important to clarify the exact nature of the associations for different types of maternal and child disability. [ABSTRACT FROM AUTHOR]

Objectives: This study aimed to explore the independent association between socioeconomic position, defined by occupation, and severe maternal morbidity among women in the UK. Design: Case-control study. Setting: The analysis was conducted as a case-control analysis, using data from a series of studies of direct causes of severe maternal morbidity undertaken through the UK Obstetric Surveillance System (UKOSS), with data collected throughout all consultant-let obstetric units in the UK. Participants: The analysis included 1144 cases and 2256 comparison women (controls). UKOSS studies from which data on case women were obtained included amniotic fluid embolism, acute fatty liver of pregnancy, eclampsia, peripartum hysterectomy, therapies for peripartum haemorrhage and uterine rupture. Primary outcome measure: Odds of severe maternal morbidity by socioeconomic group, independent of ethnicity, maternal age, smoking, pre-existing medical condition, body mass index (BMI), multiple pregnancy and past pregnancy complications. Occupation was used to classify different socioeconomic groups. Secondary outcome measure: Odds of morbidity related to ethnic group, maternal age, smoking, pre-existing medical condition, BMI, multiple pregnancy and past pregnancy complications. Results: Across the socioeconomic groups, compared with the 'managerial/professional' group, adjusted ORs were 1.17 (95% CI 0.94 to 1.45) for the 'intermediate group', 1.16 (95% CI 0.93 to 1.45) for 'routine/manual', 1.22 (95% CI 0.92 to 1.61) for 'unemployed' women and 1.51 (95% CI 1.18 to 1.94) for women with missing socioeconomic information. Women of nonwhite ethnicity, older maternal age (≥35 years), BMI ≥25 kg/m² and those with pre-existing medical condition/s, multiple pregnancy or past pregnancy complications were shown to have a significantly increased odds of severe maternal morbidity. Conclusions: This study suggests that socioeconomic position may be independently associated with an increased risk of severe maternal morbidity, although the observed association was not statistically significant. Further research is warranted to confirm this and investigate why this association might exist in a country where healthcare is universal and free at the point of access. [ABSTRACT FROM AUTHOR]

Objectives: To identify the sociodemographic factors associated with variation in area-based breastfeeding in England; to calculate the predicted breastfeeding rates adjusted for sociodemographic variations. Design: Ecological analysis of routine data using random effects logistic regression. Setting: All 151 primary care trusts (PCTs) in England 2010-2011. Outcome measures: PCT level data on breastfeeding: initiation, any and exclusive breastfeeding at 6-8 weeks. Results: There was considerable variation in breastfeeding across PCTs (breastfeeding initiation mean 72%, range 39-93%; any breastfeeding at 6-8 weeks mean 45%, range 19-83%; exclusive breastfeeding at 6-8 weeks mean 32%, range 14-58%), with London PCTs reporting markedly higher rates. Maternal age was strongly associated with area-based breastfeeding, with a 4-6% increase in odds of breastfeeding associated with a unit increase in the percentage of older mothers. Outside London, the proportion of the local population from a Black and Minority Ethnic (BME) background, compared with those from a White British background, was associated with higher breastfeeding (1-3% increase in odds per unit increase in the proportion from a BME background). Area-based deprivation was associated with reduced odds of breastfeeding (21-32% reduced odds comparing most deprived quintile to least deprived quintile). Weaker associations were observed between sociodemographic factors and breastfeeding in London PCTs. Very few PCTs reported breastfeeding figures substantially above or below the national average, having adjusted for variations in sociodemographic factors. Conclusions: Our results show striking associations between sociodemographic factors and breastfeeding at the area level, with much of the variation in breastfeeding rates explained by the sociodemographic profile. The sociodemographic context of breastfeeding is clearly important at the area level as well as the individual level. Our findings can be used to inform decision-making relating to local priorities and service provision. [ABSTRACT FROM AUTHOR]

Objective To compare school performance at age 5 years in children born at full term (39-41 weeks gestation) with those born at early term (37-38 weeks gestation), late preterm (34-36 weeks gestation), moderately preterm (32-33 weeks gestation) and very preterm (<32 weeks gestation). Design Population-based cohort (UK Millennium Cohort Study). Participants Seven thousand six hundred and fi fty children born in 2000-2001 and attending school in England in 2006. Methods School performance was measured using the foundation stage profi le (FSP), a statutory assessment by teachers at the end of the child's fi rst school year. The FSP comprises 13 assessment scales (scored from 1 to 9). Children who achieve an average of 6 points per scale and at least 6 in certain scales are classifi ed as 'reaching a good level of overall achievement'. Results Fifty-one per cent of full term children had not reached a good level of overall achievement; this proportion increased with prematurity (55% in early term, 59% in late preterm, 63% in moderately preterm and 66% in very preterm children). Compared with full term children, an elevated risk remained after adjustment, even in early term (adjusted RR 1.05, 95% 1.00 to 1.11) and late preterm children (adjusted RR 1.12, 95% CI 1.04 to 1.22). Similar effects were noted for 'not working securely' in mathematical development, physical development and creative development. The effects of late preterm and early term birth were small in comparison with other risk factors. Conclusions Late preterm and early term birth are associated with an increased risk of poorer educational achievement at age 5 years. INSETS: What is known on this topic;What this study adds.

Objective: To study recent trends in the cumulative incidence of visual impairment in childhood over a 15-year period and to assess progress against WHO goals for prevention. Design, setting and participants: Data from a population-based register of visual impairment in southern England were used to estimate cumulative incidence and trends in visual impairment (VI) and severe visual impairment/blindness (SVI/BL) for children born in 1984-1998. Causes were classified by anatomical site(s), timing of insult(s) and whether the visual impairment was potentially preventable or treatable. Results: Of 691 eligible children, 358 (53%) had VI and 323 (47%) SVI/BL. The cumulative incidence of VI to age 12 years was 7.1 (95% CI 6.4 to 7.8) per 10 000 live births and for SVI/BL was 6.2 (95% CI 5.6 to 6.9); the incidence of both decreased significantly over time. There was an inverse relationship with gestational age and birth weight, although the risk of visual impairment associated with prematurity and low birth weight decreased substantially over time. 55% of children with VI and 77% with SVI/BL had other impairments; the proportion of associated impairments among children with VI decreased over time. 130 (19%) of the children have died, with over half dying before the age of 5. Conclusions: There is evidence of a temporal decline in the incidence of VI and SVI/BL in births from 1984 to 1998 especially in very preterm and low birthweight infants. Early childhood mortality was high. The causes of visual impairment in UK children are numerous, complex and often part of a wider picture of childhood disability. [ABSTRACT FROM AUTHOR]

Objective To quantify the contribution of smoking during pregnancy to social inequalities in stillbirth and infant death. Design Population based retrospective cohort study. Setting Scottish hospitals between 1994 and 2003. Participants Records of 529 317 singleton live births and 2699 stillbirths delivered at 24-44 weeks' gestation in Scotland from 1994 to 2003. Main outcome measures Rates of stillbirth and infant, neonatal, and post-neonatal death for each deprivation category (fifths of postcode sector Carstairs-Morris scores); contribution of smoking during pregnancy ("no," "yes," or "not known") in explaining social inequalities in these outcomes. Results The stillbirth rate increased from 3.8 per 1000 in the least deprived group to 5.9 per 1000 in the most deprived group. For infant deaths, the rate increased from 3.2 per 1000 in the least deprived group to 5.4 per 1000 in the most deprived group. Stillbirths were 56% more likely (odds ratio 1.56, 95% confidence interval 1.38 to 1.77) and infant deaths were 72% more likely (1.72, 1.50 to 1.97) in the most deprived compared with the least deprived category. Smoking during pregnancy accounted for 38% of the inequality in stillbirths and 31% of the inequality in infant deaths. Conclusions Both tackling smoking during pregnancy and reducing infants' exposure to tobacco smoke in the postnatal environment may help to reduce stillbirths and infant deaths overall and to reduce the socioeconomic inequalities in stillbirths and infant deaths perhaps by as much as 30-40%. However, action on smoking on its own is unlikely to be sufficient and other measures to improve the social circumstances, social support, and health of mothers and infants are needed.

Abstract Objective: To assess the effect of an NHS walk-in centre on local primary and emergency healthcare services. Design: Before and after observational study. Setting: Loughborough, which had an NHS walk-in centre, and Market Harborough, the control town. Participants: 12 general practices. Main outcome measures: Mean daily rate of emergency general practitioner consultations, mean number of haft days to the sixth bookable routine appointment, and attendance rates at out of hours services, minor injuries units, and accident and emergency departments. Results: The change between the before and after study periods was not significantly different in the two towns for daily rate of emergency general practice consultations (mean difference - 0.02/1000 population, 95% confidence interval - 0.75 to 0.71), the time to the sixth bookable routine appointment ( -0.24 half-days, -1.85 to 1.37), and daily rate of attendances at out of hours services (0.07/1000 population, -0.06 to 0.19). However, attendance at the local minor injuries unit was significantly higher in Loughborough than Market Harborough (rate ratio 1.22, 1.12 to 1.33). Non-ambulance attendances at accident and emergency departments fell less in Loughborough than Market Harborough (rate ratio 1.17, 1.03 to 1.33). Conclusions: The NHS walk-in centre did not greatly affect the workload of local general practitioners. However, the workload of the local minor injuries unit increased significantly, probably because it was in the same building as the walk-in centre. [ABSTRACT FROM AUTHOR]

The article discusses the cohort study which examines the adverse effects on infants with moderate or late and early term weeks of gestational age. The study examines the effects of gestation on the health outcomes at three and five years, which measures the hospital admissions, growth, and wheezing. Result shows that the infants with less gestation in hospital admissions has the poor outcome and infants that were born late has worst adverse health outcome.

The article presents a study which classifies gastroschisis into simple and complex subgroups that predict outcomes of infant affected by it. The study followed 393 original birth cohort of infants with gastroschisis up until 1 year of age. Results show that the outcomes for infants with complex gastroschisis were poorer than for infants with simple gastroschisis.

The article reports on the results of research which was conducted in an effort to determine whether ethnic differences exist in the incidence of specific maternal morbidities in women giving birth in Great Britain. Researchers used the UK Obstetric Surveillance System (UKOSS) to identify cases of specific severe maternal morbidities in 229 British hospitals. They found that severe maternal morbidities occurred more than 1.5 times more often among non white women than in white women.

Objectives: To investigate risk factor associated with hospitalisation of infants with a congenital anomaly in Wales, UK., Design: A population-based cohort study., Setting: Data from the Welsh Congenital Anomaly Register and Information Service linked to the Patient Episode Database for Wales and livebirths and deaths from the Office for National Statistics., Patients: All livebirths between 1999 and 2015 with a diagnosis of a congenital anomaly, which was defined as a structural, metabolic, endocrine or genetic defect, as well as rare diseases of hereditary origin., Main Outcome Measures: Adjusted OR (aOR) associated with 1 or 2+ hospital admissions in infancy versus no admissions were estimated for sociodemographic, maternal and infant factors using multinomial logistic regression for the subgroups of all, isolated, multiple and cardiovascular anomalies., Results: 25 523 infants affected by congenital anomalies experienced a total of 50 705 admissions in infancy. Risk factors for ≥2 admissions were younger maternal age ≤24 years (aOR: 1.17; 95% CI 1.06 to 1.30), maternal smoking (aOR: 1.20; 1.10 to 1.31), preterm birth (aOR: 2.52; 2.25 to 2.83) and moderately severe congenital heart defects (aOR: 6.25; 4.47 to 8.74). Girls had an overall decreased risk of 2+ admissions (aOR: 0.84; 0.78 to 0.91). Preterm birth was a significant risk factor for admissions in all anomaly subgroups but the effect of the other characteristics varied according to anomaly subgroup., Conclusions: Over two-thirds of infants with an anomaly are admitted to hospital during infancy. Our findings identified sociodemographic and clinical characteristics contributing to an increased risk of hospitalisation of infants with congenital anomalies., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.
