RESUMO

OBJECTIVE: To assess the effect of admission cardiotocography (ACTG) versus intermittent auscultation (IA) of the fetal heart (FH) in low-risk pregnancy during assessment for possible labour on caesarean section rates. DESIGN: A parallel multicentre randomised trial. SETTING: Three maternity units in the Republic of Ireland. POPULATION: Healthy, low-risk pregnant women, at term and ≥ 18 years old, who provided written informed consent. METHODS: Women were randomised to receive IA of the FH or 20 minutes ACTG on admission for possible labour onset, using remote telephone randomisation. Both groups received IA during labour, with conversion to continuous CTG as clinically indicated. MAIN OUTCOME MEASURES: Caesarean section (primary outcome), obstetric interventions (e.g. continuous CTG during labour, fetal blood sampling, augmentation of labour) and neonatal morbidity (e.g. metabolic acidosis, admission to the neonatal intensive care unit, neonatal death). RESULTS: Based on 3034 women (1513 and 1521 randomised to IA and ACTG, respectively), there was no statistical difference between the groups in caesarean section [130 (8.6%) and 105 (6.9%) for IA and ACTG groups, respectively; relative risk (RR) 1.24; 95% CI 0.97-1.58], or in any other outcome except for use of continuous CTG during labour, which was lower in the IA group (RR 0.90, 95% CI 0.86-0.93). CONCLUSION: Our study demonstrates no differences in obstetric or neonatal outcomes between IA and ACTG for women with possible labour onset, other than an increased risk for continuous CTG in women receiving ACTG. TWEETABLE ABSTRACT: No differences in outcomes between intermittent auscultation and admission cardiotocography for women with possible labour onset.

RESUMO

OBJECTIVE: Increased fetal size is associated with shoulder dystocia during labor and subsequent need for assisted delivery. We sought to investigate if increased fetal adiposity diagnosed sonographically in late pregnancy is associated with increased risk of operative delivery. METHODS: This secondary analysis of the Genesis Study recruited 2392 nulliparous women with singleton pregnancy in cephalic presentation, in a prospective, multicenter study, to examine prenatal and intrapartum predictors of Cesarean delivery. Participants underwent ultrasound and clinical evaluation between 39 + 0 and 40 + 6 weeks' gestation. Data on fetal biometry were not revealed to patients or to their managing clinicians. A fetal adiposity composite of fetal thigh adiposity and fetal abdominal wall thickness was compiled for each infant in order to determine whether fetal adiposity > 90th centile was associated with an increased risk of Cesarean or operative vaginal delivery. RESULTS: After exclusions, data were available for 2330 patients. Patients with a fetal adiposity composite > 90th centile had a higher maternal body mass index (BMI) (25 ± 5 kg/m2 vs 24 ± 4 kg/m2 ; P = 0.005), birth weight (3872 ± 417 g vs 3585 ± 401 g; P < 0.0001) and rate of induction of labor (47% (108/232) vs 40% (834/2098); P = 0.048) than did those with an adiposity composite ≤ 90th centile. Fetuses with adiposity composite > 90th centile were more likely to require Cesarean delivery than were those with adiposity composite ≤ 90th centile (P < 0.0001). After adjusting for birth weight, maternal BMI and need for induction of labor, fetal adiposity > 90th centile remained a risk factor for Cesarean delivery (P < 0.0001). A fetal adiposity composite > 90th centile was more predictive of the need for unplanned Cesarean delivery than was an estimated fetal weight > 90th centile (odds ratio, 2.20 (95% CI, 1.65-2.94; P < 0.001) vs 1.74 (95% CI, 1.29-2.35; P < 0.001). Having an adiposity composite > 90th centile was not associated with an increased likelihood of operative vaginal delivery when compared with having an adiposity composite ≤ 90th centile (P = 0.37). CONCLUSIONS: Fetuses with increased adipose deposition are more likely to require Cesarean delivery than are those without increased adiposity. Consideration should, therefore, be given to adding fetal thigh adiposity and abdominal wall thickness to fetal sonographic assessment in late pregnancy. Copyright © 2019 ISUOG.

RESUMO

INTRODUCTION: Trauma care delivery in England has been transformed by the development of trauma networks, and the designation of trauma centres. A specialist trauma service is a key component of such centres. The aim of this survey was to determine to which extent, and how, the new major trauma centres (MTCs) have been able to implement such services. METHODS: Electronic questionnaire survey of MTCs in England. RESULTS: All 22 MTCs submitted responses. Thirteen centres have a dedicated major trauma service or trauma surgery service, and a further four are currently developing such a service. In 7 of these 17 centres, the service is or will be provided by orthopaedic surgeons, in 2 by emergency medicine departments, in another 2 by general or vascular surgeons, and in 6 by a multidisciplinary group of consultants. DISCUSSION: A large proportion of MTCs still do not have a dedicated major trauma service. Furthermore, the models which are emerging differ from other countries. The relative lack of involvement of surgeons in MTC trauma service provision is particularly noteworthy, and a potential concern. The impact of these different models of service delivery is not known, and warrants further study.

RESUMO

OBJECTIVE: To document blood component usage in the UK medical treatment facility, Afghanistan, over a period of 4 years; and to examine the relationship with transfusion capability, injury pattern and survival. BACKGROUND: Haemostatic resuscitation is now firmly established in military medical practice, despite the challenges of providing such therapy in austere settings. MATERIALS AND METHODS: Retrospective study of blood component use in service personnel admitted for trauma. Data were extracted from the UK Joint Theatre Trauma Registry. RESULTS: A total of 2618 patients were identified. Survival increased from 76 to 84% despite no change in injury severity. The proportion of patients receiving blood components increased from 13 to 32% per annum; 417 casualties received massive transfusion (≥10 units of RCC), the proportion increasing from 40 to 62%. Use of all blood components increased significantly in severely injured casualties, to a median (IQR) of 16 (9-25) units of red cell concentrate (P = 0·006), 15 (8-24) of plasma (P = 0·002), 2 (0-5) of platelets (P < 0·001) and 1 (0-3) of cryoprecipitate (P < 0·001). Cryoprecipitate (P = 0·009) and platelet use (P = 0·005) also increased in moderately injured casualties. CONCLUSIONS: The number of blood components transfused to individual combat casualties increased during the 4-year period, despite no change in injury severity or injury pattern. Survival also increased. Combat casualties requiring massive transfusion have a significantly higher chance of survival than civilian patients. Survival is the product of the entire system of care. However, we propose that the changes in military transfusion practice and capability have contributed to increased combat trauma survival.

RESUMO

BACKGROUND: Trauma systems reduce mortality and improve functional outcomes from injury. Regional trauma networks have been established in several European regions to address longstanding deficiencies in trauma care. A perception of the geography and population distribution as challenging has delayed the introduction of a trauma system in Scotland. The characteristics of trauma incidents attended by the Scottish Ambulance Service were analysed, to gain a better understanding of the geospatial characteristics of trauma in Scotland. METHODS: Data on trauma incidents collected by the Scottish Ambulance Service between November 2008 and October 2010 were obtained. Incident location was analysed by health board region, rurality and social deprivation. The results are presented as number of patients, average annual incidence rates and relative risks. RESULTS: Of the 141,668 incidents identified, 72·1 per cent occurred in urban regions. The risk of being involved in an incident was similar across the most populous regions, and decreased slightly with increasing rurality. Social deprivation was associated with greater numbers and risk. A total of 53·1 per cent of patients were taken to a large general hospital, and 38·6 per cent to a teaching hospital; the distribution was similar for the subset of incidents involving patients with physiological derangements. CONCLUSION: The majority of trauma incidents in Scotland occur in urban and deprived areas. A regionalized system of trauma care appears plausible, although the precise configuration of such a system requires further study.

RESUMO

We assessed acidosis, coagulopathy and hypothermia, before and after surgery in 51 combat troops operated on for severe blast injury. Patients were transfused a median (IQR [range]) of 27 (17-38 [5-84]) units of red cell concentrate, 27 (16-38 [4-83]) units of plasma, 2.0 (0.5-3.5 [0-13.0]) units of cryoprecipitate and 4 (2-6 [0-17]) pools of platelets. The pH, base excess, prothrombin time and temperature increased: from 7.19 (7.10-7.29 [6.50-7.49]) to 7.45 (7.40-7.51 [7.15-7.62]); from -9.0 (-13.5 to -4.5 [-28 to -2]) mmol.l⁻¹ to 4.5 (1.0-8.0 [-7 to +11]) mmol.l⁻¹; from 18 (15-21 [9-24]) s to 14 (11-18 [9-21]) s; and from 36.1 (35.1-37.1 [33.0-38.1]) °C to 37.4 (37.0-37.9 [36.0-38.0]) °C, respectively. Contemporary intra-operative resuscitation strategies can normalise the physiological derangements caused by haemorrhagic shock.

RESUMO

BACKGROUND: Improvised explosive devices (IEDs) pose a significant threat to military personnel, often resulting in lower extremity amputation and pelvic injury. Immediate management is haemorrhage control and debridement, which can involve lengthy surgery. Computed tomography is necessary to delineate the extent of the injury, but it is unclear whether to perform this during or after surgery. METHODS: The UK Joint Theatre Trauma Registry was searched to identify all UK service personnel who had a traumatic lower extremity amputation following IED injury between January 2007 and December 2010. Data were collected on injury pattern and survival. RESULTS: There were 169 patients who sustained 278 traumatic lower extremity amputations: 69 were killed in action, 16 died from their wounds and 84 were wounded in action, but survived. The median (interquartile range) Injury Severity Score was 75 (21) for those killed in action, 46 (23) for those who died from wounds and 29 (12) for survivors. There were significantly more severe head, chest and abdominal injuries (defined as a body region Abbreviated Injury Scale score of 3 or more) in patients who were killed in action than in those reaching hospital (P < 0·001). Hindquarter amputations were the most lethal, with a mortality rate of 95 per cent. Of the 100 casualties who reached hospital alive, there were nine thoracotomies, one craniotomy and 34 laparotomies. All head or torso injuries that required immediate operation were clinically apparent on admission. CONCLUSION: Higher levels of amputation were associated with greater injury burden and mortality. Intraoperative computed tomography had little value in identifying clinically significant covert injuries.

RESUMO

The aim of this study was to investigate the prevalence of moderate and extreme obesity among an Irish obstetric population over a 10-year period, and to evaluate the obstetric features of such pregnancies. Of 31,869 women delivered during the years 2000-2009, there were 306 women in the study group, including 173 in the moderate or Class 2 obese category (BMI 35-39.9) and 133 in the extreme or Class 3 obese category (BMI > or = 40).The prevalence of obese women with BMI > or = 35 was 9.6 per 1000 (0.96%), with an upward trend observed from 2.1 per 1000 in the year 2000, to 11.8 per 1000 in the year 2009 (P = 0.001). There was an increase in emergency caesarean section (EMCS) risk for primigravida versus multigravid women, within both obese categories (P < 0.001). However, there was no significant difference in EMCS rates observed between Class 2 and Class 3 obese women, when matched for parity. The prevalence of moderate and extreme obesity reported in this population is high, and appears to be increasing. The increased rates of abdominal delivery, and the levels of associated morbidity observed, have serious implications for such women embarking on pregnancy.

RESUMO

BACKGROUND: Military surgery has seen the arrival of the critical care provision and cross-sectional imaging enjoyed by civilian trauma surgeons. Ballistic injury to the thoracoabdominal region is uncommon but potentially devastating. The aim of this study was to analyze recent military experience of managing this injury complex. METHODS: The study is a retrospective analysis of patients, admitted over a 12-month period, to the British Military Hospital in Afghanistan with ballistic thoracoabdominal injuries. RESULTS: In total, 27 patients sustained combined thoracoabdominal injury with a mean new injury severity score of 29±12, revised trauma score of 5.94±2.93 and predicted survival of 71.1%±39.1%. In all, 20 (74%) patients underwent immediate operation, and 7 (26%) were initially managed nonoperatively. Of those requiring surgery, 11 required laparotomy and tube thoracostomy, and 9 required thoraco-laparotomy. Of the seven casualties who were initially observed and/or further investigated, two required laparotomy following computed tomography scanning, and five were managed conservatively, two of whom required delayed surgery. There were nine fatalities, all within 16 days of being wounded. Four patients died from exsanguination, one from a traumatic brain injury, and four from multiorgan failure. Five patients presented with cardiac arrest, two of whom survived. CONCLUSIONS: Exploration remains the default treatment. Resuscitative thoracotomy may yield unexpected survivors, even if subsequent laparotomy is required. Nonoperative management appears to be feasible in a small proportion of patients but requires careful selection supported by cross-sectional imaging.

RESUMO

Civilian liver trauma is generally sustained by blunt injury, with management strategies increasingly focusing on selective non-operative strategies and endovascular intervention. Military liver trauma is more often ballistic in nature and almost always requiring operative intervention. This article reviews established and evolving surgical techniques in the operative management of liver trauma.

RESUMO

OBJECTIVE: To determine whether the addition of placental growth factor (PlGF) measurement to current clinical assessment of women with suspected pre-eclampsia before 37 weeks' gestation would reduce maternal morbidity without increasing neonatal morbidity. DESIGN: Stepped wedge cluster randomised control trial from 29 June 2017 to 26 April 2019. SETTING: National multisite trial in seven maternity hospitals throughout the island of Ireland PARTICIPANTS: Women with a singleton pregnancy between 20+0 to 36+6 weeks' gestation, with signs or symptoms suggestive of evolving pre-eclampsia. Of the 5718 women screened, 2583 were eligible and 2313 elected to participate. INTERVENTION: Participants were assigned randomly to either usual care or to usual care plus the addition of point-of-care PlGF testing based on the randomisation status of their maternity hospital at the time point of enrolment. MAIN OUTCOMES MEASURES: Co-primary outcomes of composite maternal morbidity and composite neonatal morbidity. Analysis was on an individual participant level using mixed-effects Poisson regression adjusted for time effects (with robust standard errors) by intention-to-treat. RESULTS: Of the 4000 anticipated recruitment target, 2313 eligible participants (57%) were enrolled, of whom 2219 (96%) were included in the primary analysis. Of these, 1202 (54%) participants were assigned to the usual care group, and 1017 (46%) were assigned the intervention of additional point-of-care PlGF testing. The results demonstrate that the integration of point-of-care PlGF testing resulted in no evidence of a difference in maternal morbidity-457/1202 (38%) of women in the control group versus 330/1017 (32%) of women in the intervention group (adjusted risk ratio (RR) 1.01 (95% CI 0.76 to 1.36), P=0.92)-or in neonatal morbidity-527/1202 (43%) of neonates in the control group versus 484/1017 (47%) in the intervention group (adjusted RR 1.03 (0.89 to 1.21), P=0.67). CONCLUSIONS: This was a pragmatic evaluation of an interventional diagnostic test, conducted nationally across multiple sites. These results do not support the incorporation of PlGF testing into routine clinical investigations for women presenting with suspected preterm pre-eclampsia, but nor do they exclude its potential benefit.

RESUMO

There are no reports outlining the trends in obstetric features and clinical management of twin pregnancies in an Irish obstetric population. The aim of this study was to investigate these factors for all twin pregnancies delivered during the 19 year period between 1989 and 2007, at Galway University Hospital (GUH). There were 52,199 infants delivered at GUH, of which 1594 infants (3.05% of births) were twins, related to 797 twin pregnancies. The overall incidence of twin pregnancies was 1.52%, increasing from 0.8%-1.0% in the early years of the study to 1.7-1.8% in the latter years of the study (P<0.001). There was a significant increase in incidence of twins born to mothers aged 30-39 years, alongside a significant reduction to mothers aged 20-29 years (P<0.01). The caesarean section rate overall was 41.5% (331/797), of which 54% (n=179) were elective, and 46% (n=152) were emergency, representing an emergency caesarean section rate of 19.1% of all twin pregnancies, and of 24.6% after exclusion of elective caesarean sections. The caesarean section rate for twins increased from 30% in 1989 to greater than 50% in the latter years of the study (P<0.01), related largely to a significant increase in elective caesarean sections (P<0.01). The combined vaginal-caesarean delivery rate was remarkably low at 0.75% of all twin pregnancies, and 1% after exclusion of elective caesarean sections. The preterm delivery rates were 4.1% (<32 weeks), and 16.3% (<36 weeks), with an overall perinatal mortality rate of 37 per 1000. These findings highlight the altered demographic and clinical aspects of twin pregnancies in an Irish obstetric population.

RESUMO

OBJECTIVE: The objective of this study was to explore the association between occupational factors and pregnancy outcomes in a prospective cohort of Irish pregnant women. DESIGN: This study has a prospective design. POPULATION: The Lifeways cohort included 1124 pregnant women, 676 of whom delivered a single baby and were working at their first prenatal care visit when they filled in a self-administered questionnaire. METHODS: Occupational factors were measured using this questionnaire and included eight factors describing job and working conditions. Data including pregnancy outcomes were also obtained from clinical hospital records. Logistic regression analysis was used to adjust for well-known risk factors. MAIN OUTCOME MEASURES: Birthweight (< or =3000 g and < or =2500 g), preterm delivery (<37 gestation weeks) and small-for-gestational-age. RESULTS: Significant associations were found between physical work demands and low birthweight (< or =2500 g) and working with between a temporary contract and preterm delivery. Trends were also observed between working 40 hours or more a week and shift work, and birthweight of 3000 g or less. The study of a cumulative index showed that being exposed to at least two of these occupational factors significantly predicted birthweight of < or =3000 g (OR = 2.44, 95% CI: 1.17-5.08) and of < or =2500 g (OR = 4.65, 95% CI: 1.08-20.07) and preterm delivery (OR = 5.18, 95% CI: 1.00-27.01). CONCLUSIONS: Our findings suggest that occupational factors may predict birthweight through their predictive effects on preterm delivery. This is one of the few prospective studies on pregnancy outcomes that include working conditions. As they may be modifiable, occupational factors deserve more attention in relation to birth outcomes.

RESUMO

BACKGROUND: A comprehensive study of the effect of supramaximal exercise in lipid homeostasis of Thoroughbreds provides the basis for future research on the role of lipids on energy metabolism in racehorses. OBJECTIVE: To compare the plasma lipidome of Thoroughbreds before and after supramaximal exercise using an untargeted lipidomics approach. STUDY DESIGN: Pilot experimental study. METHODS: Four Thoroughbred horses were used. The maximal oxygen consumption (VO2 max ) was calculated for each horse. Horses then underwent treadmill exercise at the speed for which the oxygen requirements had been calculated to be 115% VO2 max . Plasma samples were obtained before (T0) and immediately (T1), 15 (T2) and 30 (T3) minutes post-exercise, and evaluated using liquid chromatography/mass spectrometry. Data analysis consisted of principal component analysis and one-way repeated measures analysis of variance. RESULTS: A total of 933 plasma lipids were detected. Supramaximal exercise-induced significant changes in the signal intensity of 13 lipids; all ubiquitous in the organism as major components of biological membranes or energy substrates. MAIN LIMITATIONS: A treadmill was used to replicate track conditions. Also, sample size involved only four horses and the statistical analyses failed to achieve the desired power of 80%. CONCLUSIONS: The findings in this pilot study suggest that supramaximal exercise induces changes in specific plasma lipids in Thoroughbred racehorses. While the biological significance of these findings remains to be determined, these results provide baseline information for future studies in lipidomics applied to equine exercise physiology. Further research is warranted to better understand the role of lipids on energy metabolism in Thoroughbred racehorses.

RESUMO

Fibrinolytic dysregulation is an important mechanism in traumatic coagulopathy. It is an incompletely understood process that consists of a spectrum ranging from excessive breakdown (hyperfibrinolysis) and the shutdown of fibrinolysis. Both hyperfibrinolysis and shutdown are associated with excess mortality and post-traumatic organ failure. The pathophysiology appears to relate to endothelial injury and hypoperfusion, with several molecular markers identified in playing a role. Although there are no universally accepted diagnostic tests, viscoelastic studies appear to offer the greatest potential for timely identification of patients presenting with fibrinolytic dysregulation. Treatment is multimodal, involving prompt hemorrhage control and resuscitation, with controversy surrounding the use of antifibrinolytic drug therapy. This review presents the current evidence on the pathophysiology, diagnostic challenges, as well as the management of this hemostatic dysfunction. LEVEL OF EVIDENCE: Level III.

RESUMO

PURPOSE: The aim of this study is to evaluate the early survival and organ damage following 30 and 60 min of thoracic resuscitative endovascular balloon occlusion of the aorta (REBOA) in an ovine model of severe hemorrhagic shock. METHODS: Eighteen sheep were induced into shock by undergoing a 35 % controlled exsanguination over 30 min. Animals were randomized into three groups: 60-min REBOA 30 min after the bleeding (60-REBOA), 30-min REBOA 60 min after the bleeding (30-REBOA) and no-REBOA control (n-REBOA). Resuscitation with crystalloids and whole blood was initiated 20 and 80 min after the induction of shock. Animals were observed for 24 h with serial potassium and lactate measurements. Autopsy was performed to evaluate organ damage. RESULTS: Two animals of the n-REBOA group died within 90 min of shock induction; no hemorrhagic deaths were observed in the REBOA groups. Twenty-four-hour survival for the 60-, 30-, and n-REBOA groups was 0/6, 5/6, and 4/6 (P = 0.002). In 60-REBOA, potassium and lactate were increased at 270-min time point: from 4.3 to 5.1 mEq/l and from 3.7 to 5.1 mmol/L, respectively. Both these values were significantly higher than in the n-REBOA group (P = 0.029 for potassium and P = 0.039 for lactate). Autopsy revealed acute tubular necrosis in all died REBOA group animals. CONCLUSIONS: In this ovine model of severe hemorrhagic shock, REBOA can be used to prevent early death from hemorrhage; however, 60 min of occlusion results in significant metabolic derangement and organ damage that offsets this gain.

RESUMO

BACKGROUND: Circulatory collapse is a leading cause of mortality among traumatic major exsanguination and in ruptured aortic aneurysm patients. Approximately 40% of patients die before hemorrhage control is achieved. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an adjunct designed to sustain the circulation until definitive surgical or endovascular repair. A systematic review was conducted for the current clinical use of REBOA in patients with hemodynamic instability and to discuss its potential role in improving prehospital and in-hospital outcome. METHODS: Systematic review and meta-analysis (1900-2017) using MEDLINE, Cochrane, EMBASE, Web of Science and Central and Emcare using the keywords "aortic balloon occlusion", "aortic balloon tamponade", "REBOA", and "Resuscitative Endovascular Balloon Occlusion" in combination with hemorrhage control, hemorrhage, resuscitation, shock, ruptured abdominal or thoracic aorta, endovascular repair, and open repair. Original published studies on human subjects were considered. RESULTS: A total of 490 studies were identified; 89 met criteria for inclusion. Of the 1436 patients, overall reported mortality was 49.2% (613/1246) with significant differences (p < 0.001) between clinical indications. Hemodynamic shock was evident in 79.3%, values between clinical indications showed significant difference (p < 0.001). REBOA was favored as treatment in trauma patients in terms of mortality. Pooled analysis demonstrated an increase in mean systolic pressure by almost 50 mmHg following REBOA use. CONCLUSION: REBOA has been used in trauma patients and ruptured aortic aneurysm patients with improvement of hemodynamic parameters and outcomes for several decades. Formal, prospective study is warranted to clarify the role of this adjunct in all hemodynamic unstable patients.

RESUMO

PURPOSE: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a technique for temporary stabilization of patients with non-compressible torso hemorrhage. This technique has been increasingly used worldwide during the past decade. Despite the good outcomes of translational studies, clinical studies are divided. The aim of this multicenter-international study was to capture REBOA-specific data and outcomes. METHODS: REBOA practicing centers were invited to join this online register, which was established in September 2014. REBOA cases were reported, both retrospective and prospective. Demographics, injury patterns, hemodynamic variables, REBOA-specific data, complications and 30-days mortality were reported. RESULTS: Ninety-six cases from 6 different countries were reported between 2011 and 2016. Mean age was 52 ± 22 years and 88% of the cases were blunt trauma with a median injury severity score (ISS) of 41 (IQR 29-50). In the majority of the cases, Zone I REBOA was used. Median systolic blood pressure before balloon inflation was 60 mmHg (IQR 40-80), which increased to 100 mmHg (IQR 80-128) after inflation. Continuous occlusion was applied in 52% of the patients, and 48% received non-continuous occlusion. Occlusion time longer than 60 min was reported as 38 and 14% in the non-continuous and continuous groups, respectively. Complications, such as extremity compartment syndrome (n = 3), were only noted in the continuous occlusion group. The 30-day mortality for non-continuous REBOA was 48%, and 64% for continuous occlusion. CONCLUSIONS: This observational multicenter study presents results regarding continuous and non-continuous REBOA with favorable outcomes. However, further prospective studies are needed to be able to draw conclusions on morbidity and mortality.

RESUMO

The Lifeways Cross-generation study was established to assess the influence of socio-economic and familial characteristics on the health status and early development of children. Between October 2001 and June 2002, 1124 women were recruited to the Lifeways study at booking or first visit to maternity hospital. Lifeways mothers were 29.4 (SD 5.9) years old at recruitment, two-thirds from greater Dublin area, 17.9% held a General Medical Services (GMS) card, 64.3% were married and 40.8% were third level educated. At uni-variate level, GMS eligibility, own and parents' education and marital status all predicted mother's self rated health during pregnancy, whilst in the final multivariate logistic regression model, GMS status, household-adjusted income, marital status and grand-maternal education were each independently predictors. The Lifeways cohort confirms the importance of social position in predicting health in pregnant Irish women.

RESUMO

This analysis of the Lifeways Cohort study mothers during pregnancy (n = 1124), utilises information from a standard food frequency questionnaire completed at baseline recruitment during early pregnancy. We demonstrate that 76% of women achieved recommended intakes of 5 plus portions of fruit and vegetables daily, though this is strongly socially patterned, inversely associated with age and positively associated with level of education. Achievement of the other recommended shelf intakes of the Food Pyramid is much lower, ranging from 12% achieving the recommended sparing intake of foods high in fat, salt or sugar, to 45% consuming the recommended 3 portions per day of meat and poultry. General medical services eligible respondents are generally less likely to achieve recommended intakes. While 61% of women under 25 years old stopped drinking during pregnancy, this dropped to 38% of expectant mothers over 35 years. Less than half (45%) of those (n = 860) who responded specifically to the question reported peri-conceptual folate supplement intake, again strongly socially patterned. These findings both provide important prevalence data and highlight the need for more concerted and supportive health promotion interventions during pregnancy.
