Previous pre-eclampsia, gestational diabetes mellitus and the risk of cardiovascular disease: A nested case-control study in Sweden. BJOG 2023. [PMID: 36974033 DOI: 10.1111/1471-0528.17454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 01/12/2023] [Accepted: 01/30/2023] [Indexed: 03/29/2023]
Abstract
OBJECTIVE Pre-eclampsia and gestational diabetes mellitus (GDM) are two common pregnancy complications that affect birth outcomes and are associated with a long-term risk of cardiovascular disease (CVD). The aims of this study were to investigate if the pre-eclampsia association with CVD is independent of GDM and modified by body mass index (BMI) or GDM. DESIGN Case-control study. SETTING Sweden. POPULATION Cases were women with a first CVD event between 1991 and 2008 and a previous pregnancy who were matched with controls without CVD (1:5) by year of birth, age and region of birth. METHODS Conditional logistic regression was used to evaluate the associations of GDM, pre-eclampsia and maternal BMI with CVD adjusted for potential confounders and effect modifications with interaction tests. MAIN OUTCOME MEASURES CVD. RESULTS There were 2639 cases and 13 310 controls with complete data. Pre-eclampsia and GDM were independent risk factors for CVD (adjusted odds ratio [aOR] 2.59, 95% CI 2.12-3.17 and aOR 1.47, 95% CI 1.04-2.09, respectively). After stratifying by maternal BMI, the adjusted association of pre-eclampsia with CVD did not differ notably between BMI groups: normal weight (aOR 2.65, 95% CI 1.90-3.69), overweight (aOR 2.67, 95% CI 1.52-4.68) and obesity (aOR 3.03, 95% CI 0.74-12.4). Similar findings were seen when stratifying on GDM/non-GDM. CONCLUSIONS Pre-eclampsia and GDM are independent risk factors for later CVD and having both during pregnancy is a major risk factor for later CVD. The association between pre-eclampsia and CVD is not modified by BMI. Effective CVD preventive programs for high-risk women are urgently needed in order to improve women's long-term health.

Abstract
AIM To assess whether incidence of maternal and neonatal outcomes for women with or without gestational diabetes mellitus (GDM) have changed over time. METHODS Population-based cohort study in Sweden including all singleton pregnancies over the period 1998-2012. GDM was diagnosed following Diabetic Pregnancy Study Group 1991 criteria. Poisson regression or negative binomial regression was used to model yearly relative change in numbers of cases and incidence of the outcomes with 95% confidence intervals (CI), and yearly absolute change in birthweight z-score. RESULTS The study included 1 455 667 pregnancies. The number of pregnancies increased over time and the overall prevalence of GDM was 1%. For women with GDM there was a significantly decreasing trend in incidence per year for large for gestational age (LGA) (0.986, 95% CI 0.975 to 0.996), birthweight z-score (-0.012, 95% CI -0.017 to -0.007) and birth trauma (0.937, 95% CI 0.907 to 0.968). The trend for small for gestational age (SGA) among women with GDM increased by an odds ratio per year (1.016, 95% CI 1.002 to 1.029). No significant interaction tests for maternal characteristics were found. Trends in outcomes for women without diabetes were similar to those for women with GDM. CONCLUSIONS This study shows that there were improvements in pregnancy outcomes for women with GDM between 1998 and 2012, although the incidence of SGA increased. Improvements followed similar trends in the background population. Inequalities in obstetric outcomes between women with GDM and those without have continued unchanged over 15 years, suggesting that new management strategies are required to reduce this gap.

Abstract
AIMS To evaluate the interaction effects of gestational diabetes (GDM) with obesity on perinatal outcomes. METHODS A population-based cohort study in Sweden excluding women without pre-gestational diabetes with a singleton birth between 1998 and 2012. Logistic regression was performed to evaluate the potential independent associations of GDM and BMI with adverse perinatal outcomes as well as their interactions. Main outcome measures were malformations, stillbirths, perinatal mortality, low Apgar score, fetal distress, prematurity and Erb's palsy. RESULTS Some 1,294,006 women were included, with a GDM prevalence of 1% (n = 14,833). The rate of overweight/obesity was 67.7% in the GDM-group and 36.1% in the non-GDM-group. No significant interaction existed. Offspring of women with GDM had significantly increased risk of malformations, adjusted odds ratio (aOR) 1.16 (95% confidence intervals 1.06-1.26), prematurity, aOR 1.86 (1.76-1. 98), low Apgar score, aOR 1.36 (1.10-1.70), fetal distress, aOR 1.09 (1.02-1.16) and Erb's palsy aOR 2.26 (1.79-2.86). No risk for stillbirth or perinatal mortality was seen. Offspring of overweight (BMI 25-29.9 kg/m2 ), obese (BMI 30-34.9 kg/m2 ) and severely obese women (BMI ≥ 35.0 kg/m2 ) had significantly increased risks of all outcomes including stillbirth 1.51 (1.40-1.62) to 2.85 (2.52-3.22) and perinatal mortality 1.49 (1.40-1.59) to 2.83 (2.54-3.15). CONCLUSIONS There is no interaction effect between GDM and BMI for the studied outcomes. Higher BMI and GDM are major independent risk factors for most serious adverse perinatal outcomes. More effective pre-pregnancy and antenatal interventions are required to prevent serious adverse pregnancy outcomes among women with either GDM or high BMI.

Abstract
INTRODUCTION Strategies to limit excessive maternal gestational weight gain could also have positive health effects for the offspring. This study informs us on the effect of an antenatal lifestyle intervention on offspring body mass index (BMI) trajectory until age five. MATERIAL AND METHODS A secondary analysis of a randomized controlled trial aimed at reducing gestational weight gain, set in Ørebro, Sweden (Clinical Trials.gov Id NCT00451425). Offspring were followed with standardized measures of weight and height until age five. Mean BMI z-score and proportion (%) of over- and undernutrition (BMI z-score > ± 2 standard deviations) was compared between groups. Risk estimates for obesity at age five were analyzed in relation to maternal gestational weight gain and prepregnancy BMI as a secondary outcome. RESULTS We analyzed 374 children at birth and 300 at age five. No significant difference in mean BMI z-score was seen at birth (0.68 (I) vs 0.56 (C), p = 0.242) or at age five (0.34 (I) vs 0.26 (C), p = 0.510) and no significant difference in proportion of over- or undernutrition was seen. Excessive maternal gestational weight gain was an independent risk factor for offspring obesity at birth (OR = 4.51, p < 0.001) but not at age five. Maternal obesity was an independent risk factor for offspring obesity at age five (OR = 4.81, p = 0.006). CONCLUSIONS Our composite antenatal lifestyle intervention did not significantly reduce the risk of obesity in offspring up until age five.

Abstract
AIM To analyse the impact of overweight and obesity on the risk of adverse maternal outcomes and fetal macrosomia in pregnancies of women treated for severe gestational diabetes. METHODS This was a population-based cohort study including all singleton pregnancies in Sweden without pre-existing diabetes in the period 1998-2012. Only mothers with an early- pregnancy BMI of ≥ 18.5 kg/m² were included. Logistic regression analysis was used to determine odds ratios with 95% CIs for maternal outcomes and fetal growth. Analyses were stratified by maternal gestational diabetes/non-gestational diabetes to investigate the impact of overweight/obesity in each group. RESULTS Of 1 249 908 singleton births, 13 057 were diagnosed with gestational diabetes (1.0%). Overweight/obesity had the same impact on the risks of caesarean section and fetal macrosomia in pregnancies with and without gestational diabetes, but the impact of maternal BMI on the risk of preeclampsia was less pronounced in women with gestational diabetes. Normal-weight women with gestational diabetes had an increased risk of caesarean section [odds ratio 1.26 (95% CI 1.16-1.37)], preeclampsia [odds ratio 2.03 (95% CI 1.71-2.41)] and large-for-gestational-age infants [odds ratio 2.25 (95% CI 2.06-2.46)]. Risks were similar in the overweight group without gestational diabetes, caesarean section [odds ratio 1.34 (1.33-1.36)], preeclampsia odds ratio [1.76 (95% CI 1.72-1.81)], large-for-gestational-age [odds ratio 1.76 (95% CI 1.74-1.79)]. CONCLUSIONS Maternal overweight and obesity is associated with similar increments in risks of adverse maternal outcomes and delivery of large-for-gestational-age infants in women with and without gestational diabetes. Obese women with gestational diabetes are defined as a high-risk group. Normal-weight women with gestational diabetes have similar risks of adverse outcomes to overweight women without gestational diabetes.

Abstract
Pornography consumption and sexual behaviour were studied, with an aim to investigate any associations. Participants were 718 students from 47 high school classes, mean age 18 years, in a medium-sized Swedish city. More men (98%) than women (72%) had ever consumed pornography. More male high consumers than low consumers or women got sexually aroused by, fantasized about, or tried to perform acts seen in a pornographic film ( P<0.001). Three-quarters of the sample had had sexual intercourse, of which 71% reported contraceptive use at first intercourse. Anal intercourse was reported by 16%, with infrequent condom use (39%). Intercourse with a friend (adjusted odds ratio (adj. OR) 2.29; 95% confidence interval (CI) 1.27–4.12) was significantly associated with high consumption of pornography among men, while anal intercourse (adj. OR 1.99; 95% CI 0.95-4.16) and group sex (adj. OR 1.95; 95% CI 0.70-5.47) tended to be associated. A significant confounder was early age of sexual debut (adj. OR 1.49; 95% CI 1.18-1.88).

Abstract
AIMS To investigate how glucose levels at diagnosis of gestational diabetes (GDM) are associated with infant birth weight and long-term risk of manifest diabetes mellitus in the mother. METHODS In a case control study GDM pregnancies (n=2085) were compared with non-GDM pregnancies matched for day of delivery and obstetric unit (n=3792). GDM was defined as capillary blood glucose (cB-glucose) ≥9.0mmol/l (plasma glucose ≥10.0mmol/l) after a 75g oral glucose tolerance test (OGTT). The GDM cohort were followed up 8.5-13.5yrs after initial diagnosis with a questionnaire, answered by 1324 GDM women (65%). RESULTS GDM women had higher mean infant birth-weight compared with controls (3682g vs. 3541g, P<0.001). In multiple linear regression analysis, birth weight was positively correlated to fasting cB-glucose at GDM diagnosis (P<0.001), increased week of gestation (P<0.001) and BMI before pregnancy (P<0.003), while 2h OGTT cB-glucose values ≥9.0mmol/l were not related. Infants born to mothers with fasting cB-glucose ≤4.5mmol/l had no increased mean birth-weight or macrosomia (≥4500g) compared to controls. In the follow up 334/1324 women (25%) of the GDM women had developed diabetes, 215 type 2 diabetes, 46 type 1 diabetes and 72 unclassified diabetes. In logistic regression fasting cB-glucose and 2h OGTT cB-glucose at diagnosis of GDM as well as BMI >25 and origin outside Europe were risk factors for manifest diabetes. CONCLUSIONS Fasting blood glucose at diagnosis of GDM gives important information besides 2h OGTT glucose about pregnancy outcome and future risk for maternal diabetes.

Neonatal encephalopathy and the association to asphyxia in labor. Am J Obstet Gynecol 2014; 211:667.e1-8.

Abstract
OBJECTIVE In cases with moderate and severe neonatal encephalopathy, we aimed to determine the proportion that was attributable to asphyxia during labor and to investigate the association between cardiotocographic (CTG) patterns and neonatal outcome. STUDY DESIGN In a study population of 71,189 births from 2 Swedish university hospitals, 80 cases of neonatal encephalopathy were identified. Cases were categorized by admission CTG patterns (normal or abnormal) and by the presence of asphyxia (cord pH, <7.00; base deficit, ≥12 mmol/L). Cases with normal admission CTG patterns and asphyxia at birth were considered to experience asphyxia related to labor. CTG patterns were assessed for the 2 hours preceding delivery. RESULTS Admission CTG patterns were normal in 51 cases (64%) and abnormal in 29 cases (36%). The rate of cases attributable to asphyxia (ie, hypoxic ischemic encephalopathy) was 48 of 80 cases (60%), most of which evolved during labor (43/80 cases; 54%). Both severe neonatal encephalopathy and neonatal death were more frequent with an abnormal, rather than with a normal, admission CTG pattern (13 [45%] vs 11 [22%]; P = .03), and 6 [21%] vs 3 [6%]; P = .04), respectively. Comparison of cases with an abnormal and a normal admission CTG pattern also revealed more frequently observed decreased variability (12 [60%] and 8 [22%], respectively) and more late decelerations (8 [40%] and 1 [3%], respectively). CONCLUSION Moderate and severe encephalopathy is attributable to asphyxia in 60% of cases, most of which evolve during labor. An abnormal admission CTG pattern indicates a poorer neonatal outcome and more often is associated with pathologic CTG patterns preceding delivery.

Abstract
Objective To identify if gestational diabetes mellitus (GDM) is a clinically useful marker of future cardiovascular disease (CVD) risk and if GDM combined with other risks (smoking, hypertension or body mass) identifies high-risk groups. Design Population-based matched case–control study. Setting National Swedish register data from 1991 to 2008. Population A total of 2639 women with a cardiovascular event and matched controls. Methods Conditional logistic regression examined associations with CVD before and after adjustment for conventional risk factors and confounders. Effect modification for the association of GDM with CVD by body mass index (BMI), smoking and chronic hypertension was assessed by stratification and interaction testing. Adjustment for diabetes post-pregnancy evaluated its mediating role. Main outcome measures Inpatient diagnoses or causes of death identifying ischemic heart disease, ischemic stroke, atherosclerosis or peripheral vascular disease. Results The adjusted odds ratios (and 95% confidence intervals) for the association of CVD with GDM are 1.51 (1.07–2.14), 2.23 (2.01–2.48) for smoking, 1.98 (1.71–2.29) for obesity and 5.10 (3.18–8.18) for chronic hypertension. In stratified analysis the association of CVD with GDM was only seen among women with BMI ≥25, with an odds ratio of 2.39 (1.39–4.10), but only women with a BMI <30 accounted for this increased risk. Adjustment for post-pregnancy diabetes attenuated it somewhat to 1.99 (1.13–3.52). Conclusions In the absence of other recognised cardiovascular risk factors, such as smoking, obesity or chronic hypertension, GDM is a useful marker of raised CVD risk among women with BMI between 25 and 29.

Abstract
OBJECTIVE High birth weight is a risk factor for neonatal complications. It is not known if the risk differs with body proportionality. The primary aim of this study was to determine the risk of adverse pregnancy outcome in relation to body proportionality in large-for-gestational-age (LGA) infants stratified by maternal gestational diabetes mellitus (GDM). RESEARCH DESIGN AND METHODS Population-based study of all LGA (birth weight [BW] >90th percentile) infants born to women with GDM (n = 1,547) in 1998-2007. The reference group comprised LGA infants (n = 83,493) born to mothers without diabetes. Data were obtained from the Swedish Birth Registry. Infants were categorized as proportionate (P-LGA) if ponderal index (PI) (BW in grams/length in cm(3)) was ≤90th percentile and as disproportionate (D-LGA) if PI >90th percentile. The primary outcome was a composite morbidity: Apgar score 0-3 at 5 min, birth trauma, respiratory disorders, hypoglycemia, or hyperbilirubinemia. Logistic regression analysis was used to obtain odds ratios (ORs) for adverse outcomes. RESULTS The risk of composite neonatal morbidity was increased in GDM pregnancies versus control subjects but comparable between P- and D-LGA in both groups. D-LGA infants born to mothers without diabetes had significantly increased risk of birth trauma (OR 1.19 [95% CI 1.09-1.30]) and hypoglycemia (1.23 [1.11-1.37]). D-LGA infants in both groups had significantly increased odds of Cesarean section. CONCLUSIONS The risk of composite neonatal morbidity is significantly increased in GDM offspring. In pregnancies both with and without GDM, the risk of composite neonatal morbidity is comparable between P- and D-LGA.

Abstract
OBJECTIVE To evaluate if acidemia in vigorous infants is a useful variable in the assessment of intrapartum care with regard to cardiotocographic (CTG) patterns during the second stage. METHODS Cases (n = 241) were infants with an umbilical artery pH < 7.05, controls (n = 482) were infants with pH ≥ 7.05. Apgar score was ≥ 7 at 5 min in both groups. CTGs during the last two hours of labor were assessed and neonatal outcomes compared. A sub-analysis of cases with metabolic acidemia: pH < 7.00 and base deficit ≥ 12 mmol/L and acidemia: 7.00 < pH < 7.05 was performed. RESULTS 63% of cases had a pathological CTG versus 26% of controls (p < 0.001). Patterns with severe variable decelerations had a significantly longer duration in cases. Metabolic acidemia was significantly associated with severe variable decelerations and decreased variability. Infants to cases were admitted to neonatal care in 19% versus 2% of controls (p < 0.001). With metabolic acidemia, 32% were admitted. CONCLUSION An umbilical artery pH < 7.05 at birth of vigorous infants may be a useful variable for quality control of intrapartum management with regard to the assessment of second-stage CTGs. Differences in duration of pathological patterns indicate passiveness in academic cases.

Abstract
Obesity is a risk factor for gestational diabetes, whereas the role of the mother's birth weight is more uncertain. We aimed to investigate the combined effect of mothers' birth-weight-for-gestational-age and early pregnancy Body Mass Index (BMI) in relation to risk of gestational diabetes. Between 1973 and 2006, we identified a cohort of 323,083 women included in the Swedish Medical Birth Register both as infants and as mothers. Main exposures were mothers' birth-weight-for-gestational-age (categorized into five groups according to deviation from national mean birth weight) and early pregnancy BMI (classified according to WHO). Rates of gestational diabetes increased with adult BMI, independently of birth-weight-for-gestational-age. However, compared to women with appropriate birth-weight-for-gestational-age [appropriate-for-gestational age (AGA); -1 to +1 SD] and BMI (<25.0), women with obesity class II-III (BMI ≥ 35.0) had an adjusted odds ratio (OR) of 28.7 (95 % confidence interval, CI 17.0-48.6) for gestational diabetes if they were born small-for-gestational-age [small for gestational age (SGA); <-2SD], OR = 20.3 (95 % CI 11.8-34.7) if born large-for-gestational-age [large-for-gestational-age (LGA); >2SD], and OR = 10.4 (95 % CI 8.4-13.0) if born AGA. Risk of gestational diabetes is not only increased among obese women, but also among women born SGA and LGA. Severely obese women born with a low or a high birth-weight-for-gestational-age seem more vulnerable to the development of gestational diabetes compared to normal weight women. Normal pre-pregnancy BMI diminishes the increased risk birth size may confer in terms of gestational diabetes. Therefore, the importance of keeping a healthy weight cannot be overemphasized.

Abstract
OBJECTIVE To determine if disproportionate body composition is a risk factor for perinatal complications in large-for-gestational-age infants born to mothers with type 1 diabetes. DESIGN Population-based cohort study. SETTING Data from the Swedish Medical Birth Registry from 1998 to 2007. POPULATION National cohort of 3517 infants born to mothers with type 1 diabetes. Only singletons with gestational age 32-43 weeks were included. METHODS Large for gestational age (LGA) was defined as birthweight > 90th centile and appropriate for gestational age (AGA) as birthweight between 10th and 90th centiles. Disproportionate (D) infants were defined as having a ponderal index [PI: calculated as birthweight in grams/(length in cm)(3) > 90th centile] and proportionate (P) as PI ≤ 90th centile. LGA infants were classified as P-LGA or D-LGA. Odds ratios were calculated for D-LGA and P-LGA infants, with AGA infants as the reference category. Odds ratios were adjusted for mode of delivery, fetal distress and stratified by gestational age. MAIN OUTCOME MEASURES The primary outcome was a composite of neonatal morbidities, i.e. any of the following diagnoses: Apgar score < 7 at 5 minutes, birth trauma (Erb's palsy or clavicle fracture), respiratory disorder, hyperbilirubinaemia or hypoglycaemia requiring treatment. RESULTS Composite morbidity was significantly more frequent in LGA as opposed to AGA infants, but there was no difference in risk between P-LGA and D-LGA infants. CONCLUSIONS High birthweight, irrespective of body proportionality, is a risk factor for neonatal complications in offspring of women with type 1 diabetes.

Abstract
OBJECTIVE To assess the risk of perinatal complications in overweight and obese women with and without type 1 diabetes (T1DM). DESIGN Prospective population-based cohort study. SETTING This study was based on data from the Swedish Medical Birth Registry from 1998 to 2007. PARTICIPANTS 3457 T1DM and 764 498 non-diabetic pregnancies were included. T1DM was identified based on ICD code O24.0. Mothers were categorised according to pre-pregnancy body mass index (BMI: weight in kilograms per height in square metres) as normal weight (BMI 18.5-24.9), overweight (BMI 25-29.9) or obese (BMI ≥30). Only women with singleton pregnancies and with data on BMI were included. PRIMARY/SECONDARY OUTCOMES: The primary outcome was large for gestational age (LGA: birth weight >90th percentile) infants. Secondary outcomes were major malformations, pre-eclampsia (PE), preterm delivery, perinatal mortality, delivery by Caesarean section and neonatal overweight. Logistic regression analysis was performed with normal weight non-diabetic women as the reference category and also within the diabetic cohort with normal weight type 1 diabetic women as the reference. The ORs were adjusted for ethnicity, maternal age, height, parity, smoking and chronic hypertension. RESULTS 35% of women with T1DM were overweight and 18% were obese, as compared with 26% and 11%, respectively, in non-diabetic pregnancies. The incidences of adverse outcome increased with greater BMI category. As compared with non-diabetic normal weight women, the adjusted OR for obese T1DM for LGA was 13.26 (95% CI 11.27 to 15.59), major malformations 4.11 (95% CI 2.99 to 5.65) and PE 14.19 (95% CI 11.50 to 17.50). T1DM was a significant effect modifier of the association between BMI and LGA, major malformations and PE (p<0.001). CONCLUSION High pre-pregnancy BMI is an important risk factor for adverse outcome in type 1 diabetic pregnancies. The combined effect of both T1DM and overweight or obesity constitutes the greatest risk. It seems prudent to strive towards normal pre-pregnancy BMI in women with T1DM.

Abstract
OBJECTIVE To characterize birth size distribution in infants born to mothers with type 1 diabetes. In particular, the relationship between birth weight (BW) and length (BL) was studied because it may provide information on different causal pathways of fetal macrosomia commonly seen in diabetic pregnancies. RESEARCH DESIGN AND METHODS This was a population-based cohort study of 3,705 infants of type 1 diabetic mothers (1,876 boys), with a gestational age of 28-43 weeks, born in Sweden between 1998 and 2007. BW and BL were retrieved from the Medical Birth Registry and expressed as SD scores (SDS). Ponderal index (PI) was calculated as BW in g/length in cm³. A BW >90th and a PI ≤ 90th percentile was defined as proportionate large-for-gestational age (LGA), whereas if both BW and PI > 90th percentile, the infant was categorized as disproportionately large. Values are mean (SD). RESULTS The BW distribution for offspring of type 1 diabetic mothers was bell-shaped, significantly broader, and markedly shifted to the right (BWSDS: 1.27 [1.48]) of the reference. Of the infants born to diabetic mothers, 47% were LGA, and among them, 46% were disproportionately large compared with 35% in nondiabetic LGA infants (P < 0.001). Female offspring of type 1 diabetic mothers had significantly higher BWSDS than males (1.34 vs. 1.20, P < 0.01), and preterm infants had higher BWSDS than term infants (1.41 vs. 1.23, P < 0.01) CONCLUSIONS Fetal macrosomia in type 1 diabetic pregnancies is due to a right-shift and broadening of the entire BW distribution. The large number of disproportionate LGA infants born to type 1 diabetic mothers suggests an underlying metabolic problem. Fetal macrosomia was more pronounced in preterm and female offspring of type 1 diabetic mothers.

Abstract
OBJECTIVE To perform comparative analyses of obstetric and perinatal outcomes between type 1 diabetic pregnancies and the general obstetric population in Sweden between 1991 and 2003. RESEARCH DESIGN AND METHODS This was a population-based study. Data were obtained from the Medical Birth Registry, covering >98% of all pregnancies in Sweden. A total of 5,089 type 1 diabetic pregnancies and 1,260,207 control pregnancies were included. Odds ratios (ORs) were adjusted for group differences in maternal age, parity, BMI, chronic hypertensive disease, smoking habits, and ethnicity. RESULTS In type 1 diabetes, preeclampsia was significantly more frequent (OR 4.47 [3.77-5.31]) as was delivery by cesarean section (5.31 [4.97-5.69]) compared with results for the general population. Stillbirth (3.34 [2.46-4.55]), perinatal mortality (3.29 [2.50-4.33]), and major malformations (2.50 [2.13-2.94]) were more common in type 1 diabetic than in control pregnancies. The risk of very preterm birth (<32 gestational weeks) was also higher among type 1 diabetic women (3.08 [2.45-3.87]). The incidence of fetal macrosomia (birth weight >or=2 SD above the mean) was increased in the diabetic group (11.45 [10.61-12.36]). CONCLUSIONS Type 1 diabetes in pregnancy is still associated with considerably increased rates of adverse obstetric and perinatal outcomes. The eightfold increased risk for fetal macrosomia in type 1 diabetic pregnancies is unexpected and warrants further investigation.

Abstract
OBJECTIVE To investigate whether there is a difference in occurrence of electrocardiogram changes suggestive of myocardial ischaemia between two different doses of oxytocin. DESIGN Double-blind randomised controlled trial. SETTING University hospital in Sweden. POPULATION A total of 103 healthy women undergoing elective caesarean section under spinal anaesthesia. METHODS The participants were randomised to 5 or 10 units of oxytocin, given as an intravenous bolus. A Holter monitor was used to record electrocardiograms and non invasive blood pressure and heart rate (HR) was monitored. A blood sample was obtained 12-hour postoperatively. MAIN OUTCOME MEASURES Depression of the ST segment. SECONDARY OUTCOMES symptoms, Troponon I levels, mean arterial pressure (MAP), HR and blood loss. RESULTS There was a significant difference in occurrence of ST depressions associated with oxytocin administration, 4 (7.7%) with 5 and 11 (21.6%) with 10 units, P < 0.05. The absolute risk reduction was 13.9% (95% confidence interval, 0.5-27.3). Decrease of mean MAP from baseline to 2 minutes differed, being 9 mmHg in the 5 unit group and 17 mmHg in the 10 unit group (P < 0.01). The increase in mean HR did not differ. Troponin I levels were increased in four subjects (3.9%). There were no differences in occurrence of symptoms, Troponin I levels, or estimated blood loss. CONCLUSION ST depressions were associated with oxytocin administration significantly more often in subjects receiving 10 units compared with 5 units. Interventions to prevent hypotension during caesarean section may reduce the occurrence of ST depressions on electrocardiograms.

Abstract
OBJECTIVE The purpose of this study was to determine whether there is a difference, by gender, in perinatal mortality in chronically hypertensive women compared with normotensive women. DESIGN Population-based prospective cohort study. SETTING Sweden. POPULATION A total of 866,188 women with singleton pregnancies registered in the Swedish Medical Birth Registry 1992-2004, of which 4749 were diagnosed with chronic hypertension. METHODS Multivariate logistic regression analysis was performed. In a first step, we adjusted for maternal characteristics and in a second step for mild and severe pre-eclampsia, gestational diabetes, placental abruption and small for gestational age. An effect modification by gender was included in the model. MAIN OUTCOME MEASURES Odds ratios (OR) for intrauterine death, neonatal death and post-neonatal death with respect to gender of offspring. RESULTS The unadjusted OR of intrauterine death was 4.12 (95% CI: 2.84-5.96) and 1.29 (95% CI: 0.67-2.48) for male and female offspring, respectively, and of neonatal death, it was 3.45 (95% CI: 2.13-5.59) and 2.17 (95% CI: 1.08-4.35) for male and female offspring, respectively. After multivariate analysis, the OR of intrauterine death was 3.07 (95% CI: 2.12-4.46) and neonatal death was 2.99 (95% CI: 1.84-4.85) for male offspring. For female offspring, the OR of intrauterine death was 0.98 (95% CI: 0.51-1.89) and neonatal death was 1.88 (95% CI: 0.93-3.79). CONCLUSION Mothers with chronic hypertension have an increased risk of perinatal mortality of their male offspring.

Abstract
OBJECTIVES To investigate self-reported sexual experiences, abortions, sexually transmitted infections (STIs), use of contraception and possible influencing factors on contraceptive use among Swedish high school students. METHODS An anonymous classroom survey was distributed to a random sample (n = 924) of 18-year-old high school students in a medium-sized Swedish city. The response rate was 78% (n = 718). RESULTS Three out of four students had experienced intercourse and the majority of them stated that they were satisfied with their sexual life. Few students reported having had an abortion (5%) or a STI (4%). Alcohol use appeared the most important contributing risk factor for non-use of contraception in relation to both first and latest intercourse, and the young men reported more unprotected latest intercourse than the young women did. CONCLUSION The fact that young men appear less inclined to use contraception is disturbing, and must be addressed in sexual education and individual counseling to promote a better sexual health for adolescents.

Abstract
OBJECTIVE The first aim of this study was to investigate the risk of pre-eclampsia, both mild and severe, in women born small for gestational age (SGA). The second aim was to investigate whether the risk is modified by pre-eclampsia in the previous generation. DESIGN Population-based cohort study. SETTING Sweden. POPULATION A population of 118 634 women registered both as newborns and as mothers in the Swedish Medical Birth Register of 1973-2003. Of these, 6883 had been born SGA. Only primiparas and singletons were included. METHODS The pregnancies that the women were born out of were analysed with regard to presence of pre-eclampsia, while their own pregnancies were analysed regarding age at delivery, smoking, body mass index and incidence of mild or severe pre-eclampsia. Multiple logistic regression analysis was used. In a first step, we adjusted for maternal characteristics, and in a second step, for pre-eclampsia in the previous generation. MAIN OUTCOME MEASURES Odds ratio for mild and severe pre-eclampsia. RESULTS In women born SGA, the adjusted odds ratio (first step) for mild pre-eclampsia was 1.19 (95% CI 1.03-1.38), while for severe pre-eclampsia it was 1.69 (95% CI 1.40-2.02) compared with those not born SGA. After the second-step adjustment, the odds ratio for mild pre-eclampsia was 1.16 (95% CI 1.00-1.35) and for severe pre-eclampsia was 1.62 (95% CI 1.35-1.95). No statistically significant effect modification from pre-eclampsia in the previous generation was shown. CONCLUSIONS Women born SGA suffer a markedly increased risk of severe pre-eclampsia. Exposure to pre-eclampsia during a woman's own fetal development significantly increases her risk of pre-eclampsia but does not modify the SGA effect.

Abstract
BACKGROUND The objective of this study was to analyse the motives behind disciplinary action in obstetric malpractice cases concerning delivery, and to evaluate the frequency of inappropriate oxytocin use in these cases. METHODS An analysis of all malpractice claims resulting in disciplinary action against physicians and midwives during the period 1996-2003. Investigations and decisions made by the Board of Medical Responsibility were reviewed with special focus on the use of oxytocin. RESULTS Of 77 cases, 60 regarded patients in labour. In the majority, there had been a normal pregnancy and spontaneous start of labour (78%). At the beginning of labour, 87% showed a normal fetal heart rate (FHR) pattern, indicating fetal well-being. In 70%, there was adverse fetal outcome with brain damage or death. The most common reason for disciplinary action was improper interpretation of fetal monitor tracings and corresponding failure to recognise fetal distress (76%). Injudicious use of oxytocin was common (68.5%), and was the primary reason for disciplinary action in 33% of the cases. CONCLUSION In a Swedish setting, a few common clinical problems pervade; interpretation of FHR patterns and the use of oxytocin account for the majority of rulings of negligence in malpractice cases regarding delivery. Analysis of the cases suggests that the adverse fetal outcomes could possibly have been prevented.

Abstract
Pornography is one of the most sought-after topics on the Internet, and is easily available for anyone, including children and adolescents. At youth centres, nurse-midwives have noticed that young people have different kinds of questions about sexual practices compared with a few years ago. The aim of this study was to gain an understanding of thoughts and reflections about pornography consumption, and its possible influence on sexual practices, among young women and men. The staff at a youth centre in a city in central Sweden asked the visitors if they had seen pornography and if they wanted to be interviewed about their experiences. Ten young women and eight men, aged 16-23 years, participated. In-depth interviews were performed and open-ended questions about pornography and sexuality were posed. The interviews were tape-recorded and transcribed verbatim. Data were analysed according to grounded theory. The core category 'Living with the current sexual norm' depicted how pornography created sexual expectations and demands, for instance, to perform certain sexual acts. The informants expressed contradictory feelings towards pornography and felt that sexuality was separated from intimacy. A moral attitude was described and examples of stereotypic gender roles were given. To deal with the current sexual norm, informants had different individual handling strategies and attitudes to pornography, namely liberal, normalization, distance, feminist or conservative. Limitations of this study were the small sample size and that results from a qualitative research study cannot be generalized. The results contribute to an understanding of how pornographic material can influence young peoples' thoughts, reflections and sexual behaviour. This indicates the importance, for personnel at youth centres and schools, to discuss sexual behaviour and how sexuality is portrayed in pornographic material with young people.

Abstract
OBJECTIVE To evaluate fasting capillary glucose as a screening test for gestational diabetes mellitus (GDM) compared with traditional risk factors and repeated random capillary glucose measurements. DESIGN Cross-sectional, population-based study. SETTING Maternal Health Care Clinics in Orebro County, Sweden. POPULATION An unselected population of women without diabetes. METHODS Fasting capillary glucose levels were measured at gestational weeks 28-32. Random capillary glucose levels were measured four to six times during pregnancy. Traditional risk factors for GDM were registered. GDM was diagnosed using a 75-g oral glucose tolerance test. MAIN OUTCOME MEASURES Sensitivity, specificity, likelihood ratios. RESULTS In 55 of 3616 women participating in the study, GDM was diagnosed before 34 weeks of gestation. For fasting capillary glucose cutoff values between 4.0 and 5.0 mmol/l, sensitivity was in the range between 87 and 47% and specificity between 51 and 96%. Using a combined screening model of traditional risk factors with fasting capillary glucose at various cutoff values increased the sensitivity only slightly compared with using fasting capillary glucose alone. CONCLUSION In this Swedish, unselected, low-risk population, fasting capillary glucose measurements were found to be an acceptable and useful screening test for GDM.

Abstract
BACKGROUND Chronic hypertension during pregnancy is associated with an increased risk for birth of small for gestational age offspring. The aim of this study was to determine whether the risk remains after consideration of maternal characteristics and superimposed pre-eclampsia. METHOD A population-based cohort study based on the Swedish Medical Birth Register 1992-98 and comprising 560 188 women aged 15-44 years with singleton pregnancies including 2,754 women with chronic hypertension. The register contains data of maternal characteristics besides maternal and fetal complications. Multiple logistic regression analysis was used. Small for gestational age was defined as birth weight less than -2SD adjusted for gestational age and sex. RESULTS Chronic hypertensive women have an independent risk for small for gestational age (OR 3.1; 95% CI 2.7-3.7) when controlling for confounding of maternal characteristics such as age, parity, BMI, smoking, and ethnic origin. After introducing superimposed pre-eclampsia in the model the risk remains but decreases (OR 2.4; 95% CI 2.1-2.9). CONCLUSION Chronic hypertension is an independent risk factor for birth of small for gestational age offspring. Pre-eclampsia is a strong mediating factor.

Abstract
BACKGROUND The aim of the study was to determine if pregnant women with chronic hypertensive disease have an independent risk for preeclampsia, gestational diabetes or placental abruption. To examine if superimposed preeclampsia in this group of women is related to an increased risk of placental abruption. METHODS This study is a population-based cohort study using the Swedish Medical Birth Register 1992-98. A population of 681 515 women aged between 15-44 years with singleton pregnancies, excluding women with systemic lupus erythematosus (SLE), diabetes mellitus and chronic renal disease were studied. Among these, 3374 women were diagnosed with chronic hypertensive disease. Multiple logistic regression analysis was performed and the outcome measures of crude and adjusted odds ratios (OR) were presented with 95% confidence intervals (CI). RESULTS Chronic hypertensive disease is associated with multiparity, age, high body mass index and Nordic ethnicity. After controlling for confounders, chronic hypertensive disease is an independent risk factor for preeclampsia (OR 3.8; 95% CI 3.4-4.3), gestational diabetes (OR 1.8; 95% CI 1.4-2.4) and placental abruption (OR 2.3; 95% CI 1.6-3.4). CONCLUSION Chronic hypertensive disease is independently associated with an increased incidence of preeclampsia, gestational diabetes and placental abruption.

Abstract
OBJECTIVE To determine whether gestational diabetes mellitus (GDM) increases the risk for preeclampsia independent of other risk factors. STUDY DESIGN The association between GDM and preeclampsia was analyzed in a population of women who had given birth to singletons registered in Swedish Medical Birth Register from 1992 through 1996 (n=430,852). RESULTS GDM occurred in 0.8% and preeclampsia in 2.9% of all pregnancies. The rate of preeclampsia was higher in the GDM than in the non-GDM group (6.1% versus 2.8%). High age, nullipara, chronic hypertension, kidney disease, and high body mass index (BMI) were all independently associated with increased risk for preeclampsia. Smoking was associated with decreased risk. Adjusted odds ratio for GDM as a risk factor for preeclampsia was 1.61 (95% confidence interval (CI) 1.39-1.86) when prepregnancy BMI, which was a true confounder, was included in the last step of the multiple logistic regression analysis. CONCLUSIONS There is an independent and significant association between GDM and preeclampsia. Obesity is a major confounding factor but could not explain the total excess risk.

Abstract
BACKGROUND To determine the value of repeated random blood glucose (R-B-glucose) measurements alone or in combination with traditional risk factors [family history of diabetes, obesity, prior large-for-gestational-age (LGA) infant or prior gestational diabetes mellitus (GDM)] to predict the outcome of the oral glucose tolerance test (OGTT). METHODS A prospective population-based study was undertaken in a Swedish county. All pregnant nondiabetic women (n = 4918) visiting the maternal health care clinics over a 2-year period were offered a 75-g OGTT in gestational weeks 28-32. Traditional risk factors and values of repeated R-B-glucose measurements were registered, as well as the results of the OGTT, in terms of fasting B-glucose and 2-h B-glucose. RESULTS A total of 3616 women (73.5%) had an OGTT. Of these, 1.7% had GDM, 1.3% impaired glucose tolerance (IGT) and 0.4% diabetes mellitus (DM). An R-B-glucose cut-off level > or =8.0 mmol/L as the only indicator for an OGTT was optimal for detecting GDM with regard to sensitivity (47.5%) and specificity (97.0%). It has the same sensitivity for detecting GDM as using traditional risk factors, but reduces the need to carry out the OGTT from 15.8% to 3.8% of the population. Combined with prior LGA infant or prior GDM as indications for the OGTT in the present study, all women with DM and 44.7% of those with IGT will be identified. Only 7.3% of the population will have to take the OGTT. CONCLUSION A random B-glucose level > or = 8.0 mmol/L prior LGA infant or prior GDM as an indicator for taking the OGTT is a simple and effective first step in a two-step screening model for GDM.

Abstract
OBJECTIVE To evaluate whether there is increased maternal or neonatal morbidity in connection with impaired glucose tolerance (IGT) during pregnancy when the condition is not treated. RESEARCH DESIGN AND METHODS During the study period of 1997-2001, in a defined geographical area in Sweden, the diagnostic criteria for gestational diabetes mellitus (GDM) were limited to the criteria for diabetes. Prospectively, 213 women who were identified with IGT during pregnancy were undiagnosed and untreated. Data on maternal and fetal outcome was collected from records. For each case subject, four control subjects were taken from the same delivery department. RESULTS The proportion of women who underwent cesarean section was significantly higher in the case subjects than in the control subjects and was independently associated with IGT. The adjusted odds ratio (OR) was 1.9 (95% CI 1.2-2.9). The proportion of infants who were large for gestational age (LGA), defined as birth weight >2 SDs greater than the mean for gestation and sex, was independently significantly associated with untreated IGT during pregnancy (OR 7.3, 95% CI 4.1-12.7). Admission to a neonatal intensive care unit (NICU) for 2 days or longer was more common (adjusted OR 2.0, 95% CI 1.1-3.8). However, 71.3% of the children in the IGT group and 87.3% of the control subjects had no neonatal complications. CONCLUSIONS There is increased independent association between cesarean section rate, prematurity, LGA, and macrosomic infants born to mothers with untreated IGT. Most of the children were healthy, but there is still increased morbidity. Therefore, to evaluate the effects of treatment, there is a need for a randomized study.

Abstract
BACKGROUND The objective of the present study was to determine prevalence of gestational diabetes mellitus (GDM) in terms of impaired glucose tolerance (IGT) and diabetes mellitus (DM), and the value of traditional anamnestic risk factors for predicting outcome of the oral glucose tolerance test (OGTT). METHODS A prospective population-based study in a defined geographic area in Sweden. All pregnant nondiabetic women (n = 4918) attending maternal health care from July 1994 to June 1996 were offered a 75g OGTT in gestational weeks 28-32. Traditional anamnestic risk factors, as well as results of the OGTT in terms of fasting-B-glucose and 2h-B-glucose, were registered. RESULTS 3616 (73.5%) women agreed to perform the OGTT. Sixty-one (1.7%) of those had GDM [47 (1.3%) had impaired glucose tolerance and 14 (0.4%) had diabetes mellitus]. 15.8% fulfilled traditional risk factor criteria. Traditional anamnestic risk factors as an indicator to perform an OGTT identified 29/61 GDM women and 9/14 women with DM. Among primiparas, 4/21 with gestational diabetes mellitus were detected. CONCLUSION Using traditional risk factors as an indicator to perform an OGTT gives a low sensitivity to detect GDM and even DM especially among primiparas.

Abstract
OBJECTIVE To compare the efficacy and safety of preprandial administration of rapid-acting lispro analogue with regular short-acting insulin to pregnant women with type 1 diabetes. STUDY DESIGN Open randomised multicentre study. Women were treated with multiple insulin injections aiming at normoglycaemia. Blood glucose was determined six times daily, HbA(1c) every 4 weeks. Diurnal profiles of blood glucose were analysed at gestational week 14 and during the study period at weeks 21, 28 and 34. PARTICIPANTS 33 pregnant women with type 1 DM were randomised to treatment with lispro insulin (n=16) or regular insulin (n=17). RESULTS Blood glucose was significantly lower (P<0.01) after breakfast in the lispro group, while there were no significant group differences in glycemic control during the rest of the day. Severe hypoglycaemia occurred in two patients in the regular group but biochemical hypoglycaemia (blood glucose <3.0 mmol/l) was more frequent in the lispro than in the regular group (5.5 vs. 3.9%, respectively). HbA(1c) values at inclusion were 6.5 and 6.6% in the lispro and regular group respectively. HbA(1c) values declined during the study period and were similar in both groups. There was no perinatal mortality. Complications during pregnancy, route of delivery and foetal outcome did not differ between the groups. Retinopathy progressed in both groups, one patient in the regular group developed proliferative retinopathy. CONCLUSION The results suggest that it is possible to achieve at least as adequate glycemic control with lispro as with regular insulin therapy in type 1 diabetic pregnancies.

Abstract
OBJECTIVE Assess the actual rate of eclampsia in Sweden, describe the clinical picture of the disease and the maternal and perinatal outcomes. METHODS Analysis of data regarding incidence of eclampsia registered in the Swedish Medical Birth Register 1991-1992. The records of all the cases with the diagnosis of eclampsia in Sweden during 1991-1992 were retrospectively evaluated regarding maternal and fetal outcomes. RESULTS The incidence of eclampsia after case review was 3.3/10,000 births. There was no maternal mortality. Severe maternal complications occurred in 30%. Recurrent fits were reported in 41%. Antenatal eclampsia was usually either not preceded by symptoms or signs of preeclampsia or by just a very short period of prodromal symptoms. Among intrapartum and postnatal cases of eclampsia, preeclampsia or high blood pressure was more frequently noted when convulsions occurred. Perinatal mortality rate was 4/80 (4.7%). Of the infants, 13% were small for gestational age. CONCLUSION Compared with earlier studies, the incidence of eclampsia has increased significantly. It is questionable whether the incidence of eclampsia could be reduced by earlier diagnosis and treatment of preeclampsia. The risk of severe complications and recurrent fits was substantial, which underlines the importance of adequate treatment of eclampsia.

Acupuncture treatment during labour--a randomised controlled trial. BJOG 2002; 109:637-44. [PMID: 12118641] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/25/2023]
Abstract
OBJECTIVE To investigate acupuncture treatment during labour with regard to pain intensity, degree of relaxation and outcome of the delivery. DESIGN Randomised controlled trial. SETTING Delivery ward at a tertiary care centre hospital in Sweden. POPULATION Ninety parturients who delivered during the period April 12, 1999 and June 4, 2000. METHODS Forty-six parturients were randomised to receive acupuncture treatment during labour as a compliment, or an alternative, to conventional analgesia. MAIN OUTCOME MEASURES Assessments of pain intensity and degree of relaxation during labour, together with evaluation of delivery outcome. RESULTS Acupuncture treatment during labour significantly reduced the need of epidural analgesia (12% vs 22%, relative risk [RR] 0.52, 95% confidence interval [CI] 0.30 to 0.92). Parturients who received acupuncture assessed a significantly better degree of relaxation compared with the control group (mean difference -0.93, 95% CI -1.66 to -0.20). No negative effects of acupuncture given during labour were found in relation to delivery outcome. CONCLUSIONS The results suggest that acupuncture could be a good alternative or complement to those parturients who seek an alternative to pharmacological analgesia in childbirth. Further trials with a larger number of patients are required to clarify if the main effect of acupuncture during labour is analgesic or relaxing.

Abstract
PURPOSE To investigate sexual behavior and attitudes toward sexuality among first-year high school students in Sweden in 1999 and to compare the sexual behavior with that reported from similar studies in 1979 and 1989. METHODS In Spring 1999, a questionnaire with 47 questions mainly of multiple-choice nature was administered to a random sample of 20 classes in senior high school in two medium-sized cities in Sweden. The median age of the students was 16 years. Differences in sexual behavior and attitudes were evaluated with the Chi-square and Student's t-test. RESULTS Almost half of the students (46%) had had intercourse, showing that the age of coitarche had not decreased during the past two decades. The median age at intercourse of those who had had intercourse was 15 years in both genders. More students in practical (vocational-technical) programs (60%) than in theoretical (college preparatory) ones (37%) had had sexual intercourse. More teenagers in theoretical (90%) than in practical programs (64%) had used contraceptives at their first intercourse, an increase from 65% in 1979 to 76% in 1999. One-fourth of the teenagers were under the influence of alcohol at the first intercourse, a decrease, compared with 1979. CONCLUSIONS Contraceptive use at coitarche has increased and alcohol use decreased over the 20-year-period. The tendency noted 10 years ago that students attending practical programs put themselves at more health risk than students in theoretical programs continues. This fact should be considered when planning for counseling and sex education.

A high rate of epidural analgesia with bupivacaine-sufentanil is consistent with a low rate of caesarean section and instrumental deliveries. Eur J Obstet Gynecol Reprod Biol 2001; 98:193-8.

Abstract
OBJECTIVE To prospectively evaluate if a high rate of epidural analgesia (EDA) with bupivacaine-sufentanil is consistent with a low rate of caesarean section, instrumental deliveries and dystocia and to evaluate maternal and fetal adverse effects of sufentanil. STUDY DESIGN Populations-based prospective descriptive study. A change of EDA from bupivacaine to low dose bupivacaine-sufentanil at the delivery unit of the hospital during 1993 resulted in a marked increase in the rate of EDA. The outcome from the study period (1994-1995) was compared to the outcome during a reference period 1991-1992. RESULTS There were no significant differences in the incidence of caesarean section and instrumental delivery for dystocia between the two periods (4.4 and 4.6%). The overall incidence of caesarean section, 9.6% and instrumental deliveries, 6.4% during the study period was lower than or comparable to the national background data (11.1 and 6.8%, respectively) while the EDA rate was markedly higher 37.8 versus 21.9%. CONCLUSION A high rate of EDA, using low dose bupivacaine and sufentanil is consistent with a low rate of caesarean section and instrumental deliveries. No apparent negative effects on the neonates or mothers were observed.
