- Progress has been made towards ascertaining the genetic predictors of ovarian stimulation in IVF. Aromatase cytochrome P450, encoded by the CYP19A1 gene, catalyses a key step in ovarian oestrogen biosynthesis. Hence, the aromatase gene is an attractive candidate for genetic studies. This study aimed to examine the genetic influences of CYP19A1 TCT trinucleotide insertion/deletion (Ins/Del) and (TTTA)(n) microsatellite intronic polymorphisms on ovarian stimulation outcome and aetiology of female infertility. IVF patients (n = 152) underwent ovarian stimulation according to recombinant FSH and gonadotrophin releasing hormone antagonist protocol. Del/Del homozygous patients with shorter TTTA repeats exhibited decreased ovarian FSH sensitivity in ovarian stimulation, which may reflect variations in aromatase gene expression during early antral follicle development. Accordingly, this study demonstrates correlations between Del allele and shorter (TTTA)(n) repeat sizes with smaller ovaries (r = -0.70, P = 0.047) and fewer antral follicles (r = 0.21, P = 0.018) on days 3-5 of spontaneous menstrual cycle, respectively. Furthermore, Del variation linked with low-repeat-number (TTTA)(n) alleles are involved in enhanced genetic susceptibility to unexplained infertility (adjusted OR = 4.33, P = 0.039) and endometriosis (r = -0.88, P = 0.026), which corroborates evidence on the overlapping patient profiles of ovarian dysfunction in both types of female infertility.

- Background: Inequality in adult health increased in Estonia during the transition period after 1991. We examined inequality in infant survival from 1992 to 2002. Methods: All 132 854 singleton live births reported to the Estonian Medical Birth Registry in 1992–2001 were linked to the Estonian Mortality Database. The effect of mother's education, nationality, marital status, and place of residence on neonatal (0–27 days) and post-neonatal (28–364 days) death was evaluated in logistic regression with adjustments for maternal age, parity, smoking, sex of the infant, birth weight, and gestational age. Results: Infant mortality decreased substantially. Risk of death in neonatal period was lowest in Tartu, with a decline from 4.9/1000 in infants born in 1992–1996 to 2.1/1000 in those born in 1997–2001. Decline in neonatal mortality in other regions was from 9.2/1000 to 5.1/1000. Persisting regional differences were unexplained by mothers' nationality, education, or marital status, or the infants' length of gestation. Decline in post-neonatal mortality was less marked and although risk differences between different socio-economic groups decreased, mothers' marital status and education in particular remained strongly associated with risk of post-neonatal death [odds ratio for infants born to mothers with basic or lower education compared to university education 3.70 (95% confidence interval 2.34–5.85) in 1992–1996 and 3.56 (2.06–6.14) in 1997–2001]. Conclusions: Infant survival improved appreciably in Estonia after 1991 and risk differences between social groups decreased. The improvements were not accompanied by reduction in the strength of the effects of social characteristics on infant death measured as risk ratios.

- BACKGROUND: Unintended pregnancies are common and when not resulting in a termination of pregnancy may lead to unintended childbirth. Unintended pregnancies are associated with increased health risks, also for women for whom pregnancy continues to childbirth. Our objective was to present the prevalence of unintended pregnancy in six European countries among pregnant women attending routine antenatal care, and to investigate the association with a history of physical, sexual and emotional abuse. METHODS: A prospective cross-sectional study, of 7102 pregnant women who filled out a questionnaire during pregnancy as part of a multi-country cohort study (Bidens) with the participating countries: Belgium, Iceland, Denmark, Estonia, Norway and Sweden. A validated instrument, the Norvold Abuse Questionnaire (NorAq) consisting of 10 descriptive questions measured abuse. Pregnancy intendedness was assessed using a single question asking women if this pregnancy was planned. Cross-tabulation, Chi-square tests and binary logistic regression analysis were used. RESULTS: Approximately one-fifth (19.2 %) of all women reported their current pregnancy to be unintended. Women with an unintended pregnancy were significantly younger, had less education, suffered economic hardship, had a different ethnic background from the regional majority and more frequently were not living with their partner. The prevalence of an unintended pregnancy among women reporting any lifetime abuse was 24.5 %, and 38.5 % among women reporting recent abuse. Women with a history of any lifetime abuse had significantly higher odds of unintended pregnancy, also after adjusting for confounding factors, AOR for any lifetime abuse 1.41 (95 % CI 1.23-1.60) and for recent abuse AOR 2.03 (95 % CI 1.54-2.68). CONCLUSION: Women who have experienced any lifetime abuse are significantly more likely to have an unintended pregnancy. This is particularly true for women reporting recent abuse, suggesting that women living in a violent relationship have less control over their fertility.

- Objectives The primary objective was to investigate the prevalence of a history of abuse among women attending routine antenatal care in six northern European countries. Second, we explored current suffering from reported abuse. Design A prospective cohort study. Setting Routine antenatal care in Belgium, Iceland, Denmark, Estonia, Norway, and Sweden between March 2008 and August 2010. Population A total of 7174 pregnant women. Methods A questionnaire including a validated instrument measuring emotional, physical and sexual abuse. Main outcome measure Proportion of women reporting emotional, physical and sexual abuse. Severe current suffering defined as a Visual Analogue Scale score of ≥6. Results An overall lifetime prevalence of any abuse was reported by 34.8% of the pregnant women. The ranges across the six countries of lifetime prevalence were 9.7–30.8% for physical abuse, 16.2–27.7% for emotional abuse, and 8.3–21.1% for sexual abuse. Few women reported current sexual abuse, 0.4% compared with 2.2% current physical abuse and 2.7% current emotional abuse. Current severe suffering was reported by 6.8% of the women who reported physical abuse, 9.8% of those who reported sexual abuse and 13.5% for emotional abuse. Conclusion A high proportion of pregnant women attending routine antenatal care report a history of abuse. About one in ten of them experiences severe current suffering from the reported abuse. In particular, these women might benefit from being identified in the antenatal care setting and being offered specialized care.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To date, little is known about differences in the knowledge, diagnosis making and treatment strategies of health care providers regarding polycystic ovary syndrome (PCOS) across different disciplines in countries with similar health care systems. To inform guideline translation, we aimed to study physician reported awareness, diagnosis and management of PCOS and to explore differences between medical disciplines in the Nordic countries and Estonia.Methods: This cross-sectional survey was conducted among 382 endocrinologists and obstetrician gynaecologists in the Nordic countries and Estonia in 2015-2016. Of the participating physicians, 43% resided in Finland, 18% in Denmark, 16% in Norway, 13% in Estonia, and 10% in Sweden or Iceland, and 75% were obstetrician-gynaecologists. Multivariable logistic regression models were run to identify health care provider characteristics for awareness, diagnosis and treatment of PCOS.Results: Clinical features, lifestyle management and comorbidity were commonly recognized in women with PCOS, while impairment in psychosocial wellbeing was not well acknowledged. Over two-thirds of the physicians used the Rotterdam diagnostic criteria for PCOS. Medical endocrinologists more often recommended lifestyle management (OR = 3.6, CI 1.6-8.1) or metformin (OR = 5.0, CI 2.5-10.2), but less frequently OCP (OR = 0.5, CI 0.2-0.9) for non fertility concerns than general obstetrician-gynaecologists. The physicians aged <35 years were 2.2 times (95% CI 1.1-4.3) more likely than older physicians to recommend lifestyle management for patients with PCOS for fertility concerns. Physicians aged 46-55 years were less likely to recommend oral contraceptive pills (OCP) for patients with PCOS than physicians aged >56 (adjusted odds ratio (OR) = 0.4, 95% CI 0.2-0.8).Conclusion: Despite well-organized healthcare, awareness, diagnosis and management of PCOS is suboptimal, especially in relation to psychosocial comorbidities, among physicians in the Nordic countries and Estonia. Physicians need more education on PCOS and evidence based information on Rotterdam diagnostic criteria, psychosocial features and treatment of PCOS, with the recently published international PCOS guideline well needed and welcomed.

- Background Few studies have examined the mode of birth among women with fear of childbirth, and the results are conflicting. The objective of this study was to assess the association between fear of childbirth and cesarean delivery in North European women. Methods A longitudinal cohort study was conducted among 6,422 pregnant women from Belgium, Iceland, Denmark, Estonia, Norway, and Sweden. Fear of childbirth was measured by the Wijma Delivery Expectancy Questionnaire during pregnancy and linked to obstetric information from hospital records. ResultsAmong 3,189 primiparous women, those reporting severe fear of childbirth were more likely to give birth by elective cesarean, (OR, 1.66 [95% CI 1.05-2.61]). Among 3,233 multiparous women, severe fear of childbirth increased the risk of elective cesarean (OR 1.87 [95% CI 1.30-2.69]). Reporting lack of positive anticipation, one of six dimensions of fear of childbirth, was most strongly associated with elective cesarean (OR 2.02 [95% CI 1.52-2.68]). A dose-effect pattern was observed between level of fear and risk of emergency cesarean in both primiparous and multiparous women. Indications for cesarean were more likely to be reported as nonmedical among those with severe fear of childbirth; 16.7 versus 4.6 percent in primiparous women, and 31.7 versus 17.5 percent in multiparous women. ConclusionHaving severe fear of childbirth increases the risk of elective cesarean, especially among multiparous women. Lack of positive anticipation of the upcoming childbirth seems to be an important dimension of fear associated with cesarean delivery. Counseling for women who do not look forward to vaginal birth should be further evaluated.

Tidskriftsartikel (refereegranskat)abstract
- Objective The main aim of this study was to assess whether a history of abuse, reported during pregnancy, was associated with an operative delivery. Secondly, we assessed if the association varied according to the type of abuse and if the reported abuse had been experienced as a child or an adult. Design The Bidens study, a cohort study in six European countries (Belgium, Iceland, Denmark, Estonia, Norway, and Sweden) recruited 6724 pregnant women attending routine antenatal care. History of abuse was assessed through questionnaire and linked to obstetric information from hospital records. The main outcome measure was operative delivery as a dichotomous variable, and categorized as an elective caesarean section (CS), or an operative vaginal birth, or an emergency CS. Non-obstetrically indicated were CSs performed on request or for psychological reasons without another medical reason. Binary and multinomial regression analysis were used to assess the associations. Results Among 3308 primiparous women, sexual abuse as an adult (≥18 years) increased the risk of an elective CS, Adjusted Odds Ratio 2.12 (1.28–3.49), and the likelihood for a non-obstetrically indicated CS, OR 3.74 (1.24–11.24). Women expressing current suffering from the reported adult sexual abuse had the highest risk for an elective CS, AOR 4.07 (1.46–11.3). Neither physical abuse (in adulthood or childhood <18 years), nor sexual abuse in childhood increased the risk of any operative delivery among primiparous women. Among 3416 multiparous women, neither sexual, nor emotional abuse was significantly associated with any kind of operative delivery, while physical abuse had an increased AOR for emergency CS of 1.51 (1.05–2.19). Conclusion Sexual abuse as an adult increases the risk of an elective CS among women with no prior birth experience, in particular for non-obstetrical reasons. Among multiparous women, a history of physical abuse increases the risk of an emergency CS.
