- Objective. To investigate the risk for anal sphincter tears (AST) in infibulated women. Design. Population-based cohort study. Setting. Nationwide study in Sweden. Population. The study population included 250 491 primiparous women with a vaginal singleton birth at 37–41 completed gestational weeks during 1999–2008. We only included women born in Sweden and in Africa. The African women were categorized into three groups; a Somalian-group, n = 929, where over 95% are infibulated; the Eritrea-Ethiopia-Sudan-group, n = 955, where the majority is infibulated, compared to other African countries, n = 1035, where few individuals are infibulated, but had otherwise similar anthropometric characteristics. These women were compared to 247 572 Swedish-born women. Methods. Register study with data from the National Medical Birth Registry. Main outcome measures. AST in non-instrumental and instrumental vaginal delivery. Results. Compared to Swedish-born women, women from Somalia had the highest odds ratio for AST in all vaginal deliveries: 2.72 (95% CI 2.08–3.54), followed by women from Eritrea-Ethiophia-Sudan 1.80 (1.41–2.32) and other African countries 1.23 (0.89–1.53) after adjustment for major risk factors. Mediolateral episiotomy was associated with a reduced risk of AST in instrumental deliveries. Conclusion. Delivering African women from countries where infibulation is common have an increased risk of AST compared with Swedish-born women, despite delivering in a highly technical quality healthcare setting. AST can cause anal incontinence and it is important to investigate risk factors for this and try to improve clinical routines during delivery to reduce the incidence of this complication.

- Introduction: Severe obstetric complications increase with the number of previous cesarean deliveries. In the Nordic countries most women have two children. We present the risk of severe obstetric complications at the delivery following a first elective or emergency cesarean and the risk by intended mode of second delivery. Material and methods: A two-year population-based data collection of severe maternal complications in women with two deliveries in the Nordic countries (n = 213 518). Denominators were retrieved from the national medical birth registers. Results: Of 35 450 first cesarean deliveries (17%), 75% were emergency and 25% elective. Severe complications at second delivery were more frequent in women with a first cesarean than with a first vaginal delivery, and rates of abnormally invasive placenta, uterine rupture and severe postpartum hemorrhage were higher after a first elective than after a first emergency cesarean delivery [relative risk (RR) 4.1, 95% confidence intervals (CI) 2.0-8.1; RR 1.8, 95% CI 1.3-2.5; RR 2.3, 95% CI 1.5-3.5, respectively]. A first cesarean was associated with up to 97% of severe complications in the second pregnancy. Induction of labor was associated with an increased risk of uterine rupture and severe hemorrhage. Conclusion: Elective repeat cesarean can prevent complete uterine rupture at the second delivery, whereas the risk of severe obstetric hemorrhage, abnormally invasive placenta and peripartum hysterectomy is unchanged by the intended mode of second delivery in women with a first cesarean. Women with a first elective vs. an emergency cesarean have an increased risk of severe complications in the second pregnancy.

- Objective: To assess the rates and characteristics of women with complete uterine rupture, abnormally invasive placenta, peripartum hysterectomy, and severe blood loss at delivery in the Nordic countries. Design: Prospective, Nordic collaboration. Setting: The Nordic Obstetric Surveillance Study (NOSS) collected cases of severe obstetric complications in the Nordic countries from April 2009 to August 2012. Sample and methods: Cases were reported by clinicians at the Nordic maternity units and retrieved from medical birth registers, hospital discharge registers, and transfusion databases by using International Classification of Diseases, 10th revision codes on diagnoses and the Nordic Medico-Statistical Committee Classification of Surgical Procedure codes. Main outcome measures: Rates of the studied complications and possible risk factors among parturients in the Nordic countries. Results: The studied complications were reported in 1019 instances among 605362 deliveries during the study period. The reported rate of severe blood loss at delivery was 11.6/10000 deliveries, complete uterine rupture was 5.6/10000 deliveries, abnormally invasive placenta was 4.6/10000 deliveries, and peripartum hysterectomy was 3.5/10000 deliveries. Of the women, 25% had two or more complications. Women with complications were more often >35years old, overweight, with a higher parity, and a history of cesarean delivery compared with the total population. Conclusion: The studied obstetric complications are rare. Uniform definitions and valid reporting are essential for international comparisons. The main risk factors include previous cesarean section. The detailed information collected in the NOSS database provides a basis for epidemiologic studies, audits, and educational activities.

- Objective: To assess the prevalence and risk factors of emergency peripartum hysterectomy. Design:Nordic collaborative study. Population605362 deliveries across the five Nordic countries. Methods: We collected data prospectively from patients undergoing emergency peripartum hysterectomy within 7days of delivery from medical birth registers and hospital discharge registers. Control populations consisted of all other women delivering on the same units during the same time period. Main outcome measures: Emergency peripartum hysterectomy rate. Results: The total number of emergency peripartum hysterectomies reached 211, yielding an incidence rate of 3.5/10000 (95% confidence interval 3.0-4.0) births. Finland had the highest prevalence (5.1) and Norway the lowest (2.9). Primary indications included an abnormally invasive placenta (n=91, 43.1%), atonic bleeding (n=69, 32.7%), uterine rupture (n=31, 14.7%), other bleeding disorders (n=12, 5.7%), and other indications (n=8, 3.8%). The delivery mode was cesarean section in nearly 80% of cases. Previous cesarean section was reported in 45% of women. Both preterm and post-term birth increased the risk for emergency peripartum hysterectomy. The number of stillbirths was substantially high (70/1000), but the case fatality rate stood at 0.47% (one death, maternal mortality rate 0.17/100000 deliveries). Conclusions: A combination of prospective data collected from clinicians and information gathered from register-based databases can yield valuable data, improving the registration accuracy for rare, near-miss cases. However, proper and uniform clinical guidelines for the use of well-defined international diagnostic codes are still needed.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The Nordic medical birth registers have long been used for valuable clinical research. Their collection of data for more than four decades offers unusual possibilities for research across generations. At the same time, serum and blotting paper blood samples have been stored from most neonates. Two large cohorts (approximately 100000 births) in Denmark and Norway have been described by questionnaires, interviews and collection of biological samples (blood, urine and milk teeth), as well as a systematic prospective follow-up of the offspring. National patient registers provide information on preceding, underlying and present health problems of the parents and their offspring. Researchers may, with permission from the national authorities, obtain access to individualized or anonymized data from the registers and tissue-banks. These data allow for multivariate analyses but their usefulness depends on knowledge of the specific registers and biological sample banks and on proper validation of the registers.

Birth centre care : reproduction and infant health
- 2004
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis has two general aims, to investigate factors affecting women s decision to have a second baby and to study the effect of birth centre care on infant outcome. The specific aims were to investigate 1) whether birth centre care during a woman s first pregnancy had an effect on her future reproduction, 2) whether a negative experience of the first birth had en effect on future reproduction, and 3) whether birth centre care had an effect on perinatal mortality 4) and on morbidity during the infant s first month. Nulliparous women randomly allocated to in-hospital birth centre care (n=505) and to standard maternity care (n=479) in early pregnancy were followed during a period of 7-10 years after the birth. Information about a second birth was collected from the Swedish Medical Birth Register and analysed by the Kaplan Meier method. No statistically significant differences were found between the groups in terms of having a second baby and the time to second birth (median: 2.85 versus 2.82 years, log-rank 1.26; p=0.26). Experience of childbirth was assessed in 617 first-time mothers. Information relating women s global assessment of the birth experience (questionnaire two months postpartum) and various background variables (questionnaire in early pregnancy) was linked to the Swedish Medical Birth Register. Women with a negative experience had fewer subsequent children and a longer interval to the second baby. 38% of women with a negative experience did not have another baby during the following 8 10 years, compared with 17% of those with a less negative experience (p<0.001). Two studies investigated perinatal mortality and infant morbidity in all women (n=3256) admitted to an in-hospital birth centre from 1989 to 1999. Data were compared with the outcomes for all the other women in the Greater Stockholm who gave birth in standard care during the same period and who met the same medical low-risk criteria as in the birth centre group (n=180 380). Outcome data were collected from the Swedish Medical Birth Register, the Swedish Hospital Discharge Register and medical records. Logistic regression analyses were performed to control for potential confounding background factors. No statistically significant difference in the overall perinatal mortality rate was found between the birth centre group and the standard care group (OR 1.5; 0.9 2.4), but the infants of primiparas were at higher risk in the birth centre group (OR 2.2; 1.3 3.9). Infants in the birth centre group had a higher risk of respiratory problems (OR 1.5; 1.2 1.8) and a lower risk of clavicle and other fractures (OR 0.4; 0.3 0.6). In conclusion, birth centre care during a woman s first pregnancy does not appear to affect future reproduction, but a negative overall childbirth experience does. Birth centre care might be associated with a higher risk of perinatal mortality in first-born babies, minor respiratory problems and a lower risk of birth trauma such as fractures. It is important to consider maternal and infant risk factors in the planning of models for childbirth care.

Tidskriftsartikel (refereegranskat)abstract
- ABSTRACT: BACKGROUND: The use of antenatal care (ANC) varies between countries and in different settings within each country. Most previous studies of ANC in Vietnam have been cross-sectional, and conducted in rural areas before the year 2000. This study aims to compare the pattern and the adequacy of ANC used in rural and urban Vietnam following two cohorts of pregnant women. METHODS: A comparative study with two cohorts comprising totally 2132 pregnant women were followed in two health and demographic surveillance sites, one rural and one urban in Hanoi province, Vietnam. The women were quarterly interviewed using a structured questionnaire until delivery. The primary information obtained was the number and the content of ANC visits. RESULTS: Almost all women reported some use of ANC. The average number of visits was much lower in the rural setting (4.4) than in the urban (7.7). In the rural area, 77.2% of women had at least three visits and 69.1% attended ANC during the first trimester. The corresponding percentages for the urban women were 97.2% and 97.2%. Only 20.3% of the rural women compared to 81.1% of the urban women received all core ANC services. As a result, the adequate use of ANC was 5.2 times in the urban than in the rural setting (78.3% compared to 15.2%). Nearly all women received ultrasound examination during pregnancy with a mean value of 6.0 scans per woman in the urban area and 3.5 in the rural. Most rural women used ANC at commune health centres and private clinics while urban women mainly visited public hospitals. Expenditure related to ANC utilization for the urban women was 7.1 times that for the urban women. CONCLUSION: The women in the rural area attended ANC later, had fewer visits and received much fewer services than urban women. The large disparity in ANC adequacy between the two settings suggests special attention for the ANC programme in rural areas focusing on its content. Revision and enforcement of the national guidelines to improve the behaviour and practice of both users and providers are necessary. Key words: Antenatal care, adequacy, disparities, urban - rural comparison, Vietnam.
