ICU admissions from an obstetrical hospital.

To ascertain the anaesthetic complications requiring post-anaesthetic respiratory support in a large obstetrical hospital, the hospital records of obstetrical patients admitted to an adjacent general intensive care unit (ICU) were studied. Obstetrical patients who required mechanical ventilation following anaesthetic complications were identified and their hospital records reviewed. In a ten-year period there were 61,435 women delivered at the Mater Mothers Hospital (MMH) in Brisbane, Queensland, Australia. Of these 24,161 had an anaesthetic associated with delivery including 7,452 general anaesthetics (GAs) and 16,709 regional anaesthetics (RAs). There were also 3,708 GAs and 17 RAs for procedures other than delivery. During this period there were 126 obstetrical admissions to the ICU. Sixteen were due to anaesthetic complications, twelve followed GA and four followed RA. Complications included anaphylaxis, high block and failure of tracheal intubation. The incidence of a major complication of a GA causing admission to the ICU was 1 in 932 and for RA was 1 in 4177 when these were given for delivery (P less than 0.01). If a complication requiring ICU admission and mechanical ventilation is used as the criterion of safety it appears that RA is safer than a GA for delivery.

Informed consent for obstetrics management: a urogynecologic perspective.

Obstetric management has been modified for conditions with acute, short-term consequences (i.e. breech presentation). It is timely to address those conditions related to the vaginal birth process which may have a delayed but significant negative impact on the mother's quality of life (i.e. urinary and fecal incontinence) but which may be reduced by selectively avoiding the vaginal birth process. The known possible consequences, and other associated risks and benefits, should be discussed with the pregnant patient and her spouse, in order to allow their input into the obstetric decision-making process and to individualize management. Urogynecologists are in a unique, no-conflict-of-interest position to further the acceptance of the concept of obstetrical informed consent. Cesarean delivery should not be seen as a failure of obstetric management, but rather as a safe and acceptable option to the vaginal delivery process, chosen after completing an informed decision-making process.

Obstetric factors and relative risk of neonatal germinal layer/intraventricular hemorrhage.

One hundred fifty-five inborn infants with a birth weight less than or equal to 1,500 gm were prospectively evaluated for germinal layer/intraventricular hemorrhage. Maternal characteristics, obstetric factors, and neonatal condition in the immediate newborn period were analyzed as possible risk factors for germinal layer/intraventricular hemorrhage. Early germinal layer/intraventricular hemorrhage or hemorrhages identified during the first 24 hours of life were observed in 85 (55%) of these infants. Another 37 (24%) had germinal layer/intraventricular hemorrhage after 24 hours of age (late germinal layer/intraventricular hemorrhage). None of the maternal and obstetric variables, including labor, mode of delivery, and presentation, appeared to increase the risk of germinal layer/intraventricular hemorrhage. The immediate neonatal condition, birth weight, gestational age, and intrauterine growth, all influenced the occurrence of germinal layer/intraventricular hemorrhage, especially early germinal layer/intraventricular hemorrhage. We suggest that future studies to investigate the role of maternal or obstetric factors in the pathogenesis of germinal layer/intraventricular hemorrhage should discriminate early from late germinal layer/intraventricular hemorrhage. Obstetric factors are more likely to influence the early onset of germinal layer/intraventricular hemorrhage; their effect, if any, becomes less discernible later.

How do obstetric variables influence the dimensions of the birth experience as assessed by Salmon's item list (SIL-Ger)?

OBJECTIVE: To analyse the effect of obstetric variables on four dimensions of the birth experience. DESIGN/PARTICIPANTS: The birth experience of 251 German-speaking women was assessed at 48-96 h postpartum by means of Salmon's item list--German-language version (SIL-Ger). METHOD/MAIN OUTCOME MEASURES: Statistical correlations and variances between four dimensions of the birth experience (fulfillment, emotional adaptation, negative emotional experience, physical discomfort) and common obstetric variables were calculated. The explained variance is assessed by a stepwise regression analysis. RESULTS: In general the variance explained by the investigated obstetric variables per se is low. The mode of delivery affects the dimension of negative emotional experience with a constant qualitative worsening in the order of spontaneous deliveries, instrumental deliveries, elective and unplanned caesarean sections. Epidurals are associated neither with positive nor with negative evaluative feelings. To assess the impact of duration, the subjective latent phase of labour has to be taken into consideration in addition to the duration of labour itself. Not only very long durations of labour, but also very short ones may induce negative evaluative feelings in the immediate postpartum. CONCLUSIONS: Further research on this question must include the aspect of the parturients' subjective perception of both obstetric procedures and the attending staff. Clinicians should be aware that epidurals and elective caesarean sections do not necessarily enhance positive evaluative feelings in the immediate postpartum.

Severe obstetric complications and birth characteristics in preterm or term delivery were accurately recalled by mothers.

OBJECTIVE: This study examined the accuracy of maternal recall of obstetric complications and birth characteristics and its determinants for both preterm and term deliveries 3-9 years ago. METHODS: In 101 preterm and 107 term deliveries at the National Taiwan University Hospital during 1995-2000, recall data were obtained by telephone interview with the mothers and were matched with medical records. RESULTS: Among 10 obstetric complications assessed, the accuracy of maternal recall could either have high sensitivity and high specificity (Cesarean section, gestational hypertension, and induced labor), low to moderate sensitivity and high specificity (pre-eclampsia, breech, and cord loops), or low sensitivity and low specificity (ante partum vaginal bleeding, edema, and proteinuria). The correlations between maternal recall and medical records for birth weight (r = .95) and gestational age (r =.93) in the preterm group were slightly higher than those in the term group (r = .89 and .83, respectively). Factors associated with higher recall accuracy included preterm delivery, first birth order, and lower total parity, but no factor consistently related to maternal accuracy for all obstetric complications and birth characteristics. CONCLUSION: The accuracy of maternal recall on obstetric complications varied depending on the nature of complications examined, whereas that on birth characteristics was high.

The management and welfare of some common ovine obstetrical problems in the United Kingdom.

This review approaches sheep welfare during the periparturient period from a veterinary practitioner viewpoint. At the most fundamental husbandry level, the general hygiene standards adopted on many sheep farms in the United Kingdom (UK) during the lambing period are unacceptable and require urgent improvement. Concerns also arise from obstetrical conditions attended by farmers which cause pain that can be identified using clinical criteria such as altered demeanour and behaviour of the ewe, and the presence of inflammation of the reproductive tract. Reduced production is evidenced by poor milk production and hungry lambs, the necessity to rear such lambs artificially and, in neglected cases, death of the ewe and her lambs. The correction of dystocia, periparturient vaginal, uterine and rectal prolapses is greatly facilitated after epidural injection of lignocaine, or a combination of xylazine and lignocaine administered by a veterinary surgeon. However, the perceived high professional fees charged for these services, and for Caesarean operations, result in few sheep receiving veterinary care, with such neglect directly contributing to poor welfare standards and an increased ewe mortality rate during the periparturient period. Whilst ending any welfare concern, the destruction of ewes rather than requesting veterinary services purely for economic reasons is a disturbing trend in sheep production in the UK and raises concerns regarding positive interaction between veterinary practitioner and farmer. In this article, veterinary treatments which provide effective analgesia are described and costed for obstetrical conditions in sheep. Recommended treatment protocols are described for the common obstetrical problems in sheep. In addition to appropriate treatment of obstetrical problems and alleviation of pain, if veterinary involvement could reduce ewe periparturient mortality from estimated figures of 4-2% this would save an estimated 400,000 ewes annually in the UK. Sheep welfare could be considerably improved by practising veterinarians providing practical instruction to small groups of clients with funding provided by government agencies.

Obstetric management of 219 infants with hypoplastic left heart syndrome.

OBJECTIVE: The objective of this study was to describe the obstetric parameters from 219 deliveries of infants with hypoplastic left heart syndrome. STUDY DESIGN: The Pediatric Cardiovascular Surgery Database at the University of Michigan was searched, and cases of neonates with the diagnosis of hypoplastic left heart syndrome were found. Obstetric records were then reviewed. RESULTS: One hundred sixty-one infants (74%) were delivered vaginally and 58 (26%) were delivered by the cesarean route. The mean gestational age at delivery was 38.9 weeks. Mean Apgar scores at 1 and 5 minutes were 7 and 8, respectively. Ninety percent were delivered at term and 10% were delivered before 37 weeks. The diagnosis of hypoplastic left heart syndrome was made antenatally in 82 cases (37%) and neonatally in 137 cases (63%). In the antenatal group the mean gestational age at diagnosis was 27 weeks. Karyotype analysis was performed in 32 of all cases (15%), with 8 fetuses revealing an abnormal karyotype. Seven cases were 45,X and 1 was trisomy 21. CONCLUSION: Staged reconstruction surgery has markedly improved survival for neonates born with isolated hypoplastic left heart syndrome. Our review suggests that, aside from determining the karyotype, no further obstetric interventions seem warranted. While awaiting spontaneous labor at term, the planned mode of delivery should be vaginal, with cesarean delivery performed for routine obstetric indications only.

Changes in maternal characteristics and obstetric practice and recent increases in primary cesarean delivery.

OBJECTIVE: To estimate the contribution of changes in maternal characteristics (namely, age, parity, prepregnancy weight, weight gain in pregnancy, smoking status) and obstetric practice (namely, labor induction, epidural anesthesia, delivery by an obstetrician, midpelvic forceps delivery) to recent increases in primary cesarean delivery rates. METHODS: We studied all deliveries in Nova Scotia, Canada, between 1988 and 2000 after excluding women who had a previous cesarean delivery (n = 127,564). Logistic regression was used to study the effect of changes in maternal characteristics and obstetric practice on primary cesarean delivery rates. The effect of changes in midpelvic forceps delivery was examined through ecologic Poisson regression. RESULTS: Primary cesarean delivery rates increased from 13.4% of deliveries in 1988 to 17.5% in 2000. This was due to increases in cesarean deliveries for dystocia (14% increase), breech (24% increase), suspected fetal distress (21% increase), hypertension (47% increase), and miscellaneous indications (73% increase). Adjustment for maternal characteristics reduced the temporal increase in primary cesarean delivery rates between 1988-1991 and 1998-2000 from 21% (95% confidence interval [CI] 16%, 25%) to 2% (95% CI -2%, 7%). Additional adjustment for obstetric practice factors further reduced period effects. Midpelvic forceps delivery was significantly and negatively associated with primary cesarean delivery (P =.001). CONCLUSION: Recent increases in primary cesarean delivery rates are a consequence of changes in maternal characteristics. Obstetric practice, which has altered due to changes in maternal characteristics and concerns related to fetal and maternal safety, has also contributed to increases in primary cesarean delivery.

Effects of a refugee-assistance programme on host population in Guinea as measured by obstetric interventions.

BACKGROUND: Since 1990, 500000 people have fled from Liberia and Sierra Leone to Guinea, west Africa, where the government allowed them to settle freely, and provided medical assistance. We assessed whether the host population gained better access to hospital care during 1988-96. METHODS: In Guéckédou prefecture, we used data on major obstetric interventions performed in the district hospital between January, 1988, and August, 1996, and estimated the expected number of births to calculate the rate of major obstetric interventions for the host population. We calculated rates for 1988-90, 1991-93, and 1994-96 for three rural areas with different numbers of refugees. FINDINGS: Rates of major obstetric interventions for the host population increased from 0.03% (95% CI 0-0.09) to 1.06% (0.74-1.38) in the area with high numbers of refugees, from 0.34% (0.22-0.45) to 0.92% (0.74-1.11) in the area with medium numbers, and from 0.07% (0-0.17) to 0.27% (0.08-0.46) in the area with low numbers. The rate ratio over time was 4.35 (2.64-7.15), 1.70 (1.40-2.07), and 1.94 (0.97-3.87) for these areas, respectively. The rates of major obstetric interventions increased significantly more in the area with high numbers of refugees than in the other two areas. INTERPRETATION: In areas with high numbers of refugees, the refugee-assistance programme improved the health system and transport infrastructure. The presence of refugees also led to economic changes and a "refugee-induced demand". The non-directive refugee policy in Guinea made such changes possible and may be a cost-effective alternative to camps.

Mechanical ventilation in an obstetric population: characteristics and delivery rates.

OBJECTIVE: The purpose of this study was to describe the characteristics and outcomes of obstetric patients who require mechanical ventilation. STUDY DESIGN: A review was conducted of obstetric patients who required mechanical ventilation and who received care at our institutions between 1990 and 1998. Data that were collected included maternal demographics, medical condition that necessitated ventilation, delivery status, duration of ventilation, onset of parturition while receiving ventilation, mode of delivery, and maternal and early neonatal morbidity or death. RESULTS: Fifty-one women were identified; 43 women(84%) received care in the labor and delivery setting. The most common admission diagnoses were preeclampsia/eclampsia (44%), labor/preterm labor (14%), and pneumonia (12%). Forty-three women (86%) were undelivered on admission (mean gestational age, 31.6 weeks). Delivery occurred in 37 women (86%) during their admission; 24 women (65%) underwent cesarean delivery. Eleven women began labor while receiving ventilation; 6 were delivered vaginally. The maternal mortality rate was 14% (7/51 women), and the perinatal mortality rate was 11% (4/37 fetuses). CONCLUSION: A large number of obstetric patients who receive mechanical ventilation will require delivery because of their condition. Centers that care for such women should form a treatment strategy to coordinate obstetric and medical care for this unique population

Occipital posterior and occipital transverse positions: reappraisal of the obstetric risks.

Malpositions in labour in a vertex-presenting fetus are known to be associated with increased risks of operative delivery A retrospective analysis of all deliveries over 4 years in a university teaching obstetric unit was performed using the available obstetric database. All cases of live births with cephalic presenting babies after 36 completed gestational weeks were analysed, and included 17,533 out of 20,533 total deliveries over the study period. The study group included those cases with occipital posterior and transverse positions, based on the documentation of the position of the vertex at the time of delivery, or at the last clinical examination before obstetric intervention, while occipital anterior cases constituted the control group. The overall incidence of malpositions was 14%, and operative delivery rate in the study group was 82.5% versus 20.7% in the control group. After excluding cases of operative delivery for non-mechanical indications, such as fetal distress, the adjusted odds ratio for the malposition group was 9.8 (95% CI 8.91-10.8) for total assisted delivery and 30.2 (95% CI 25.6-35.5) for Caesarean section compared to the occipital anterior group. Malpositions are definitely associated with a marked increase in the risk of operative delivery including Caesarean section. Labour complicated by malposition should be considered high risk, and should warrant due preparation for obstetric intervention.

Randomised trial of educational visits to enhance use of systematic reviews in 25 obstetric units.

OBJECTIVE: To evaluate the effectiveness of an educational visit to help obstetricians and midwives select and use evidence from a Cochrane database containing 600 systematic reviews. DESIGN: Randomised single blind controlled trial with obstetric units allocated to an educational visit or control group. SETTING: 25 of the 26 district general obstetric units in two former NHS regions. SUBJECTS: The senior obstetrician and midwife from each intervention unit participated in educational visits. Clinical practices of all staff were assessed in 4508 pregnancies. INTERVENTION: Single informal educational visit by a respected obstetrician including discussion of evidence based obstetrics, guidance on implementation, and donation of Cochrane database and other materials. MAIN OUTCOME MEASURES: Rates of perineal suturing with polyglycolic acid, ventouse delivery, prophylactic antibiotics in caesarean section, and steroids in preterm delivery, before and 9 months after visits, and concordance of guidelines with review evidence for same marker practices before and after visits. RESULTS: Rates varied greatly, but the overall baseline mean of 43% (986/2312) increased to 54% (1189/2196) 9 months later. Rates of ventouse delivery increased significantly in intervention units but not in control units; there was no difference between the two types of units in uptake of other practices. Pooling rates from all 25 units, use of antibiotics in caesarean section and use of polyglycolic acid sutures increased significantly over the period, but use of steroids in preterm delivery was unchanged. Labour ward guidelines seldom agreed with evidence at baseline; this hardly improved after visits. Educational visits cost pound860 each (at 1995 prices). CONCLUSIONS: There was considerable uptake of evidence into practice in both control and intervention units between 1994 and 1995. Our educational visits added little to this, despite the informal setting, targeting of senior staff from two disciplines, and donation of educational materials. Further work is needed to define cost effective methods to enhance the uptake of evidence from systematic reviews and to clarify leadership and roles of senior obstetric staff in implementing the evidence.

Emergency peripartum hysterectomy in a tertiary obstetric center: 8-year evaluation.

OBJECTIVE: The aim of the study was to present the incidence, indications, and operative morbidity and mortality in pregnant women undergoing emergency peripartum hysterectomy (EPH) at a tertiary obstetric institution. METHODS: In this retrospective clinical study, performed during the period 1995-2003, 17 EPH procedures were recorded in a total of 21,659 deliveries carried out at Department of Gynecology and Obstetrics, Osijek Clinical Hospital in Osijek, Croatia. Data on the incidence of EPH in total number of deliveries, rate of EPH in vaginal delivery and cesarean section, indications for EPH, and maternal and fetal/early neonatal morbidity and mortality were derived from operative protocols and medical records of hospitalized patients. RESULTS: During the 8-year study period, the incidence of EPH in total number of deliveries was 0.078%. Out of 17 EPH procedures, 5 (29.41%) were performed after vaginal delivery and 12 (70.59%) during cesarean section, elective in five and urgent in seven cases. The indications for EPH included severe peripartum hemorrhage with placenta previa in four, placenta previa percreta in four, various forms of invasive malplacentation (placenta accreta, increta, percreta) in five, uterine rupture in two cases, and atony along with massive retroperitoneal hematoma due to rupture of periuterine vascular bundle during cesarean section in one multipara. EPH was carried out in 12 multipara and five primipara. Lesions of urinary bladder occurred in three cases and were managed by suture. Twelve patients received blood transfusion, whereas development of hemorrhagic shock necessitated transfer to Intensive Care Unit in three patients. No late complications or maternal mortality were recorded. Sixteen total hysterectomies and one supracervical hysterectomy were performed. One case of intrauterine fetal death was caused by total abruptio placenta and uterine rupture during the patient's transport from a primary obstetric institution. CONCLUSION: Invasive malplacentation is a major isolated risk factor for EPH, as shown in the present study. Other risk factors for EPH are massive hemorrhage because placenta previa, uterine atony and uterine rupture associated with multiparity, and previous cesarean section. A great proportion of EPH procedures can be prevented by the introduction of compressive operative methods such as B-Lynch suture in the obstetric algorithms, which will certainly favorably reflect in future fertility and genital health of the female population.

Socio-demographic profile and obstetric experience of fistula patients managed at the Addis Ababa Fistula Hospital.

Obstetric experience, clinical and socio-economic characteristics, and reasons for preference of place of delivery of 639 fistula patients admitted to the Addis Ababa Fistula Hospital between May 1999 and February 2000 are described About 94% of fistula patients were married and 83.6% had been through with the delivery caused the fistula before the age of 20. The mean ages at the first marriage and at the causative delivery were 14.7 (sd=2.6) and 17.8 (sd=3.2) years respectively. Mean height of fistula patients studied was 149 cms (sd=8). About 64% were primiparous, 44% (279) delivered at home, and labor lasted for 3.8 days on average. Majority of fistula patients mentioned distance as a main problem for the delays. Lack of money, poor knowledge and delay in referral were the other frequently mentioned reasons for the delays. About 62%(399) of fistula patients owned nothing valuable. Of 279 patients delivered at home 186 were those who owned nothing. Out of 180-fistula patients mentioned distance as the major problem, 103 (57%) stayed at home for delivery. About 54% of fistula patients were already divorced on arrival to the hospital and this figure varied among women with different parity and among those owning different property. Teenage and short stature are observed features of fistula patients. The study also showed the huge problems faced by fistula patients in accessing emergency obstetric care services. Analytic study is recommended to compare the magnitude of these problems among other mothers with different obstetric outcome. Meanwhile, community education about problems following teenage pregnancy, sign and symptoms of obstructed labor and the advantage of institutional delivery might reduce the occurrence rate of obstetric fistula. Community organized fund and maternity waiting areas for young and short expecting mothers are among other recommendations to be considered.

Obstetric hospitalizations in the United States for women with systemic lupus erythematosus and rheumatoid arthritis.

OBJECTIVE: To estimate the national occurrence of pregnancies in women with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) and to compare pregnancy outcomes in these patients with those in women with pregestational diabetes mellitus (DM) and with the general obstetric population. METHODS: We studied the 2002 Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project to estimate the number of obstetric hospitalizations, deliveries, and cesarean deliveries in women with SLE, RA, pregestational DM, and the general obstetric population. Pregnancy outcomes included length of hospital stay, hypertensive disorders including preeclampsia, premature rupture of membranes, and intrauterine growth restriction. RESULTS: Of an estimated 4.04 million deliveries, 3,264 occurred in women with SLE, 1,425 in women with RA, and 13,574 in women with pregestational DM. Women with SLE, RA, and pregestational DM had significantly increased rates of hypertensive disorders compared with the general obstetric population (23.2%, 11.1%, 27.4%, and 7.8%, respectively), longer hospital stays, and significantly higher risk of cesarean delivery. Although women with SLE, RA, and pregestational DM were significantly older than women in the general obstetric population, disparities in the risk of adverse outcomes of pregnancy remained statistically significant after adjustment for maternal age. CONCLUSION: To our knowledge, this is the first study to examine national data on pregnancy outcomes in women with common rheumatic diseases. As with underlying pregestational DM, women with SLE and RA appear to have a higher age-adjusted risk of adverse outcomes of pregnancy and longer hospital stays than do pregnant women in the general population, and careful antenatal monitoring should be performed.

Effects of aspirin on placenta and perinatal outcomes in patients with poor obstetric history.

OBJECTIVE: The aim of this study was to compare a low-dose aspirin treatment on placental and perinatal effects in the patients with poor obstetric history such as preeclampsia, intrauterine growth retardation (IUGR) in previous pregnancy. STUDY DESIGN: This retrospective study of 86 pregnant women was conducted between April 2002 and June 2005. In this study period 364 placentas were examined and the patients with poor obstetric history such as IUGR and preeclampsia were selected. Then the patients were assigned to three groups; group 1 (n = 30) was composed of women with no risk in previous pregnancy; group 2 (n = 27) was composed of patients with poor obstetric history (e.g., preeclampsia, IUGR) who were treated with aspirin and patients in group 3 (n = 29) had poor obstetric history without any treatment (patients who were started to follow-up after 14 weeks of gestation). Patients in group 2 were treated with a low-dose aspirin (80 mg/day) as soon as a urinary pregnancy test was positive. Treatment was usually stopped at 34 completed weeks of gestation. On histopathologic examination of the placenta, uteroplacental vascular pathologic features and secondary villous damage (such as fibrinoid necrosis of desidual vessels, villous infarct, severely increased villous fibrosis, severely increased syncytiotrophoblast knotting, obliteration of the vessel lumen, severely increased villous hypervascularity) and also lesions involving coagulation (such as excessive perivillous fibrin deposition, multiple occlusive thrombi in uteroplacental vessels, avascular villi ) were examined. RESULTS: There were no significant differences between the groups with respect to maternal age, body mass index at the first trimester and delivery. Also there were no significant differences among groups with respect to placental weight, fetal height, weight, gestational week, umbilical artery pH, pO2, pCO2 and base excess status. The incidences of preeclampsia were 3.3, 7.4, 6.8% and the incidences of IUGR were 6.7, 11.1, 6.8% in the groups, respectively (P > 0.05 for both). Although the percentages of all pathologic findings were higher in groups 2 and 3, these differences were not statistically important. CONCLUSION: When low-dose aspirin is taken, starting at the beginning of pregnancy in patients with poor obstetric history, there are still high frequencies of uteroplacental vascular and related villous lesions persisted on placental bed. Also it has no beneficial effects on perinatal outcomes in these patients.

A comparison of informed consent for obstetric anaesthesia in the USA and the UK.

The practice of 75 UK and 75 US obstetric anaesthetists in obtaining informed consent for obstetric anaesthesia (for caesarean section) and obstetric analgesia (for labour) was compared using a postal questionnaire. The response rate was approximately 60% for each group. Of the US anaesthetists 47% obtained separate written consent for obstetric anaesthesia compared to 22% of the UK group (P=0.012). Corresponding percentages for epidural analgesia were 52% for the US, and 15% for the UK (P < 0.001). Significantly more of the listed risks and benefits relating to general anaesthesia were discussed by the US anaesthetists compared to the UK group, median (interquartile range), 6 (4-7) and 3 (1-4), P < 0.001. There was no significant difference in discussion before regional anaesthesia but the US group discussed more information before epidural analgesia for labouring mothers obtunded by pain or drugs. These results suggest that discussion and documentation of informed consent for obstetric anaesthesia and analgesia could be improved in both countries, especially the UK.

Obstetric optimality and emotional problems and substance use in young adulthood.

BACKGROUND: Pregnancy and delivery are complex processes, and isolated obstetric complications rare and often accompanied or followed by a number of others. AIMS: To study the relationship between the overall obstetric situation (as opposed to single obstetric risk factors) and emotional and substance use disorders in young adulthood, and to analyse whether these links are mediated by temperaments in childhood. STUDY DESIGN: In a prospective birth cohort (n=3162), questionnaires were sent to mothers and teachers when the child was 7-10 years old, and to the children when they were 20-25 years old. SUBJECTS: Six hundred and eighty-two cohort members with complete data sets at three ages (perinatal, childhood, and young adulthood). OUTCOME MEASURES: Emotional problems and substance use in young adulthood. MAIN RESULTS: Substance use in young adulthood was predicted better by the overall obstetrical optimality score than emotional problems were. Links studied were stronger for men than for women. CONCLUSIONS: This study demonstrated the use of an aggregated obstetrical optimality score in analysing the associations between early risk factors and emotional problems and substance use in young adulthood.
