- Objective: To identify the long-term risk for low back pain among women with previous severe low back pain during pregnancy.Methods: In a previous prospective study, 79 pregnant women developed low back pain severe enough to require sick leave. Twelve years later a questionnaire was sent to 62 of these women and 84 controls who did not develop severe low back pain during pregnancy. The questionnaire asked about occupation, low back pain in general and during later pregnancies, and sick leave due to low back pain. There were also questions regarding use of oral contraceptives and its possible relation to low back pain.Results: The response rate was 84% in the back pain group and 80% among controls. The two groups were similar according to the percentage of women having had another pregnancy (33 of 52 [63%] versus 39 of 67 [58%]) but ten (19%) of the women with previous low back pain stated they had refrained from another pregnancy because of their fear of low back pain compared with only one control. Almost all women (31 of 33) with previous severe low back pain experienced the same symptoms in a subsequent pregnancy, compared with 17 of 39 (44%) controls. Even when they were not pregnant, women with previous low back pain suffered more often and used more sick leave due to low back pain (44 of 52 versus 43 of 67, chi(2) = 5.68, P < .05). The location (sacroiliac joint or lumbar affection) of the previous low back pain did not affect the long-term prognosis. In a logistic regression model, previous low back pain during pregnancy was the only independent risk factor for low back pain during a subsequent pregnancy, whereas an occupation involving physical demand did not affect the results. However, together with previous low back pain during pregnancy, heavy occupation increased the risk for current nonpregnant low back pain.Conclusion: Women with severe low back pain during pregnancy have an extremely high risk for experiencing a new episode of severe low back pain during another pregnancy and when not pregnant.

- Objective: To assess whether estrogen treatment given to postmenopausal women without vasomotor symptoms improves balance more than placebo. Methods: Forty healthy postmenopausal women without vasomotor symptoms were randomized to transdermal 17▀-estradiol (E2) 50 ╡g/day for 14 weeks or identical transdermal placebo patches. Postural balance was measured with dynamic posturography before and after 4, 12, and 14 weeks of therapy. In this test, the visual, vestibular, and somatosensory systems were provoked with increasing difficulty and body sway was measured with a dual forceplate. A low score showed large sway and a score of 100 showed no sway at all. Results: Thirty-eight women completed the study. Both groups had normal balance for their ages and near maximum scores in the three easier balance tests at baseline. In the most difficult test, both groups improved their postural balance significantly (from 13 to 32 and from 22 to 39, respectively) after 4 weeks. Thereafter, no change was seen. One problem was low statistical power, but the relative change in balance did not differ between groups. The comparison did not show even a minute advantage of E2 over placebo, so a study with higher power would probably not have shown a more pronounced effect of estrogen than placebo. The change over time did not differ between groups, which indicates a significant learning effect.Conclusion: In women without vasomotor symptoms, estrogen therapy did not seem to increase postural balance significantly more than placebo. However, we could not rule out that estrogens affect postural balance in women with vasomotor symptoms. Copyright (C) 2000 The American College of Obstetricians and Gynecologists.

- OBJECTIVE: To determine whether use of steroid hormone contraceptives modifies immune defense parameters of the vaginal epithelium in humans. METHODS: Vaginal biopsies were collected during the follicular and luteal phases in regularly menstruating women (controls) and in women using combined oral contraceptives, depot-medroxyprogesterone acetate injections, or levonorgestrel implants. Fifteen healthy women (aged 20-34 years) were enrolled in each group. Biopsies were analyzed in a blinded manner. Epithelial thickness was estimated by morphometry. Immune cells were analyzed by immunomorphometry with cell-type-specific monoclonal antibodies. RESULTS: The epithelium of controls harbored 241+/-35 leukocytes (CD45+ cells) per mm2 (mean+/-1 standard error of the mean), and the thickness was 261+/-16 microm. T lymphocytes (CD3+) dominated, and cytotoxic or suppressor T cells (CD8+) were more frequent than T helper cells (CD4:CD8 ratio: 0.7+/- 0.1). Macrophages (CD68+) constituted the second-largest population, followed by Langerhans cells (CD1a+). B cells, natural killer cells, monocytes, and granulocytes were generally absent. There were no significant differences between the follicular and luteal phases. The epithelium was significantly thicker in all three groups that used hormonal contraceptive (333+/-9 microm) compared with controls, and it exhibited superficial hyperplasia. The frequency of intraepithelial leukocytes (CD45+) was increased in depot-medroxyprogesterone acetate (P<.001) and levonorgestrel implant users (P<.04). In depot-medroxyprogesterone acetate users, this was explained by an increased frequency of the CD8+ T lymphocyte subset. CONCLUSION: Hormonal contraceptives induce hyperplasia of the vaginal epithelium. The significant changes in the intraepithelial leukocyte population in depot-medroxyprogesterone acetate and levonorgestrel implant users most probably reflect altered local immune capacity.

- OBJECTIVE: To identify and test the predictive power of potential independent risk factors of postpartum depressive symptoms during pregnancy and the perinatal period. METHODS: We conducted a case-control study where 132 women with postpartum depressive symptoms were selected as an index group and 264 women without depressive symptoms as a control group. Data related to sociodemographic status, medical, gynecologic, and obstetric history, pregnancy, and perinatal events were collected from standardized medical records. RESULTS: The strongest risk factors for postpartum depressive symptoms were sick leave during pregnancy and a high number of visits to the antenatal care clinic. Complications during pregnancy, such as hyperemesis, premature contractions, and psychiatric disorder were more common in the postpartum depressed group of women. No association was found between parity, sociodemographic data, or mode of delivery and postpartum depressive symptoms. CONCLUSION: Women at risk for postpartum depression can be identified during pregnancy. The strongest risk factors, sick leave during pregnancy and many visits to the antenatal care clinic, are not etiologic and might be of either behavioral or biologic origin. The possibilities of genetic vulnerability and hormonal changes warrant further investigation to reach a more thorough understanding.

- OBJECTIVE: To assess whether being physically abused during pregnancy increases the risk of a low birth weight (LBW) infant. METHODS: We conducted a hospital-based case-control study in León, Nicaragua. Cases consisted of 101 newborns with a birth weight under 2500 g, and for each case two controls with a birth weight over 2500 g were selected randomly from infants born the same day. Anthropometry of newborns was done immediately after birth, and background information and data on experiences of violence and potential confounders were obtained through private interviews with mothers. Crude and adjusted odds ratios (ORs) and population-attributable proportion were calculated for exposure to partner abuse in relation to LBW. Multivariate logistic regression analysis was used to control for potential confounding. RESULTS: Seventy-five percent of LBW newborns (cases) were small for gestational age and 40% were preterm. Twenty-two percent of the mothers of LBW infants had experienced physical abuse during pregnancy by their intimate partners compared with 5% of controls. Low birth weight was associated with physical partner abuse even after adjustment for age, parity, smoking, and socioeconomic status (OR 3.9; 95% confidence interval 1.7, 9.3). Given a causal interpretation of the association, about 16% of the LBW in the infant population could be attributed to physical abuse by a partner in pregnancy. CONCLUSION: Physical abuse by a partner during pregnancy is an independent risk factor for LBW.

- OBJECTIVE: To investigate the obstetric outcome and health care consumption during pregnancy, delivery, and the early postpartum period in an unselected population-based sample of pregnant women diagnosed with antenatal depressive and/or anxiety disorders, compared with healthy subjects. METHODS: Participants were 1,495 women attending 2 obstetric clinics in Northern Sweden. The Primary Care Evaluation of Mental Disorders was used to evaluate depressive and anxiety disorders in the second trimester of pregnancy. To assess demographic characteristics, obstetric outcome, and complications, the medical records of the included women were reviewed. RESULTS: Significant associations were found between depression and/or anxiety and increased nausea and vomiting, prolonged sick leave during pregnancy and increased number of visits to the obstetrician, specifically, visits related to fear of childbirth and those related to contractions. Planned cesarean delivery and epidural analgesia during labor were also significantly more common in women with antenatal depression and/or anxiety. CONCLUSION: There is an association between antenatal depressive and/or anxiety disorders and increased health care use (including cesarean deliveries) during pregnancy and delivery.

- OBJECTIVE: To estimate whether weight loss or low gestational weight gain in class I-III obese women is associated with adverse maternal and neonatal outcomes compared with gestational weight gain within the new Institute of Medicine recommendations. METHODS: This was a population-based cohort study, which included 32,991 obesity class I, 10,068 obesity class II, and 3,536 obesity class III women who were divided into four gestational weight gain categories. Women with low (0-4.9 kg) or no gestational weight gain were compared with women gaining the recommended 5-9 kg concerning obstetric and neonatal outcome after suitable adjustments. RESULTS: Women in obesity class III who lost weight during pregnancy had a decreased risk of cesarean delivery (24.4%; odds ratio [OR] 0.77, 95% confidence interval [CI] 0.60-0.99), large-for-gestational-age births (11.2%, OR 0.64, 95% CI 0.46-0.90), and no significantly increased risk for pre-eclampsia, excessive bleeding during delivery, instrumental delivery, low Apgar score, or fetal distress compared with obese (class III) women gaining within the Institute of Medicine recommendations. There was an increased risk for small for gestational age, 3.7% (OR 2.34, 95% CI 1.15-4.76) among women in obesity class III losing weight, but there was no significantly increased risk of small for gestational age in the same group with low weight gain. CONCLUSION: Obese women (class II and III) who lose weight during pregnancy seem to have a decreased or unaffected risk for cesarean delivery, large for gestational age, pre-eclampsia, excessive postpartum bleeding, instrumental delivery, low Apgar score, and fetal distress. The twofold increased risk of small for gestational age in obesity class III and weight loss (3.7%) is slightly above the overall prevalence of small-for-gestational-age births in Sweden (3.6%).

The risk of atonic uterine hemorrhage increased rapidly with increasing BMI. There was a twofold increased risk in obesity class III (1.8%). No association was found between postpartum hemorrhage with retained placenta and maternal obesity. There was an increased risk for postpartum hemorrhage for women with a BMI of 40 or higher (5.2%) after normal delivery (odds ratio [OR] 1.23, 95% confidence interval [CI] 1.04-1.45]) compared with normal-weight women (4.4%) and even more pronounced (13.6%) after instrumental delivery (OR 1.69, 95% CI 1.22-2.34) compared with normal-weight women 8.8%). Maternal obesity was a risk factor for the use of heparin-like drugs (OR 2.86, 95% CI 2.22-3.68). less thanbrgreater than less thanbrgreater thanCONCLUSION: The increased risk for atonic postpartum hemorrhage in the obese group has important clinical implications, such as considering administration of prophylactic postpartum uterotonic drugs to this group.

- OBJECTIVE: To evaluate whether adverse neonatal outcome, defined as birth injuries or severe illnesses in the newborn, was associated with maternal body mass index (BMI) in singleton pregnancies overall and depending on mode of delivery. METHODS: This was a cohort study including 1,024,471 women. Data were collected from the Swedish Medical Birth Registry. Women were categorized into six classes of BMI. Obese women were compared with normal weight women regarding adverse neonatal outcome after suitable adjustments. Four modes of delivery were evaluated: vaginal delivery; instrumental vaginal delivery; elective cesarean delivery; and emergency cesarean delivery. RESULTS: Compared with neonates born to women of normal weight, neonates born to women with BMIs of 40 or more (morbidly obese) were at increased risk of birth injury to the peripheral nervous system (odds ratio [OR] 3.80, 95% confidence interval [CI] 2.83-5.12; 0.2% compared with 0.6%), birth injury to the skeleton (OR 2.59, 95% CI 2.10-3.21; 0.5% compared with 1.1%), respiratory distress syndrome (OR 2.08, 95% CI 1.88-2.30; 2.9 compared with 5.8%), bacterial sepsis (OR 2.90, 95% CI 2.43-3.46; 0.6% compared with 1.7%), convulsions (OR 3.43, 95% CI 2.63-4.47; 0.2% compared with 0.8%), and hypoglycemia (OR 3.48, 95% CI 3.20-3.78; 2.4% compared with 7.9%). For morbidly obese women, elective cesarean delivery and vaginal delivery were associated with twice the increased risk of adverse neonatal outcomes when compared with women of normal weight. CONCLUSION: Neonates born to morbidly obese women are at markedly increased risk of adverse neonatal outcome regardless of mode of delivery. Obstetricians should not disregard the neonatal problems associated with elective cesarean delivery for morbidly obese women.

- OBJECTIVE: To evaluate whether morbidly obese women have an increased risk of pregnancy complications and adverse perinatal outcomes. METHODS: In a prospective population-based cohort study, 3,480 women with morbid obesity, defined as a body mass index (BMI) more than 40, and 12,698 women with a BMI between 35.1 and 40 were compared with normal-weight women (BMI 19.8-26). The perinatal outcome of singletons born to women without insulin-dependent diabetes mellitus was evaluated after suitable adjustments. RESULTS: In the group of morbidly obese mothers (BMI greater than. 40) as compared with the normal-weight mothers, there was an increased risk of the following outcomes (adjusted odds ratio, 95% confidence interval): preeclampsia (4.82, 4.04, 5.74), antepartum stillbirth (2.79, 1.94,4.02), cesarean delivery (2.69, 2.49,2.90), instrumental delivery (1.34, 1.16, 1.56), shoulder dystocia (3.14, 1.86, 5.31), meconium aspiration (2.85, 1.60, 5.07), fetal distress (2.52, 2.12,2.99), early neonatal death (3.41, 2.07,5.63), and large-for-gestational age (3.82, 3.50, 4.16). The associations were similar for women with BMIs between 35.1 and 40 but to a lesser degree. CONCLUSION: Maternal morbid obesity in early pregnancy is strongly associated with a number of pregnancy complications and perinatal conditions. tricians and Gynecologists.

- OBJECTIVE: To establish optimal gestational weight gain for each maternal body mass index (BMI) category based on significant risk estimates of adverse maternal and fetal outcome. METHODS: The study population consisted of 298,648 singleton pregnancies delivered in Sweden between January 1, 1994, and December 31, 2004. The number of individuals in each weight gain class was compared with the number of individuals in all other weight gain classes in the same BMI group with regard to adverse maternal and fetal outcome. Odds ratios were calculated after suitable adjustments. RESULTS: The optimal gestational weight gain in women by prepregnancy BMI was 9-22 lb (4-10 kg) for BMI less than 20, 5-22 lb (2-10 kg) for BMI 20-24.9, less than 20 lb (less than 9 kg) for BMI 25-29.9, and less than 13 lb (less than 6 kg) for BMI of 30 or more. CONCLUSION: The gestational weight gain limits for BMI categories determined in this large population-based cohort study from Swedish Medical Registers showed that a decreased risk of adverse obstetric and neonatal outcomes was associated with lower gestational weight gain limits than was earlier recommended, especially among obese women. © 2007 The American College of Obstetricians and Gynecologists.

- A prospective double-blind study was performed to evaluate the effect of prophylactic antibiotic treatment before induced abortion. Eight hundred consecutive women admitted for first-trimester abortion, without signs of genital infection or antibiotic use in the last three weeks, were included in the study. Doxycycline 400 mg or placebo was given as a single oral dose ten to 12 hours before vacuum aspiration. Ninety-one women (11.8%) returned to the hospital with suspected complications. Thirty-two of these women were diagnosed as having pelvic inflammatory disease, eight of whom (2.1%) had received doxycycline before the abortion and 24 of whom (6.2%) had received placebo, a statistically significant difference (P less than .01). A history of pelvic inflammatory disease increased the risk of developing it again after an abortion.

- OBJECTIVE: To assess the Pearl Index for risk of ectopic pregnancy in women using levonorgestrel-releasing intrauterine systems (LNG-IUS) with hormonal reservoirs of 13.5 mg, 19.5 mg, or 52 mg. METHODS: This was a retrospective cohort study. Women diagnosed with an ectopic pregnancy in Stockholm County, Sweden, between January 1, 2014, and December 31, 2019, were identified through the electronic medical record system. The final analysis included 2,252 cases of ectopic pregnancy. Information on age, reproductive and medical history, as well as current use of contraception was retrieved. The time of intrauterine device (IUD) insertion before ectopic pregnancy and the numbers of sold LNG-IUS during the study period were used to calculate the incidence rate for ectopic pregnancy during use per 100 woman-years (Pearl Index). RESULTS: Among women with an ectopic pregnancy diagnosis, 105 presented with a known type of hormonal IUD in situ, of whom 94 were included in the calculations of the Pearl Index. The estimated Pearl Index for ectopic pregnancy was 0.136 (95% CI 0.106-0.176) for the LNG-IUS 13.5-mg, 0.037 (95% CI 0.021-0.067) for the LNG-IUS 19.5-mg, and 0.009 (95% CI 0.006-0.014) for the LNG-IUS 52-mg. With the 52-mg LNG-IUS as referent, the relative risk (RR) for ectopic pregnancy was higher during the first year for LNG 13.5-mg (RR 20.59, 95% CI 12.04-35.21), and for both 13.5-mg (RR 14.49, 95% CI 9.01-23.3) and 19.5-mg (RR 4.44, 95% CI 1.64-12.00) during the total study period. CONCLUSION: The absolute risk of ectopic pregnancy during the use of LNG-IUS at any doses was low. The results show that the lower the dose of the IUD, the higher the risk of an ectopic pregnancy. Higher-dose LNG-IUS should be considered when providing contraceptive counseling to a woman with known risk factors for ectopic pregnancy who are considering a hormonal IUD.

- OBJECTIVE: To evaluate the perinatal and 2-year outcomes in pregnancies complicated by preterm premature rupture of membranes (PROM) during the second trimester. METHODS: Fifty-three consecutive singleton pregnancies with PROM at 14 to 28 weeks of gestation were studied retrospectively. Management goals were to prolong the pregnancies to 32 weeks through expectant management and to avoid fetal compromise through closer monitoring and active intervention, when necessary, after 23 weeks. Outcome of the surviving infants was based on neurologic, audiometric, and ophthalmologic examinations at 2 years of corrected age. RESULTS: Rupture of membranes occurred at 14-19 weeks (mean 17.4 weeks) in 10 women, at 20-25 weeks (mean 24.0 weeks) in 24, and at 26-28 weeks (mean 27.6 weeks) in 19. The median latency periods to delivery were 72 days, 12 days, and 10 days when rupture of membranes occurred at 14-19 weeks, 20-25 weeks, and 26-28 weeks, respectively. The overall incidence of chorioamnionitis was 28%. There were no fetal deaths and nine neonatal deaths. When rupture of membranes occurred at 14-19 weeks, 20-25 weeks, and 26-28 weeks, the perinatal survival rates were 40%, 92%, and, 100%, respectively. Pulmonary hypoplasia accounted for seven deaths. Of the live-born infants, 81% were alive at 2 years of corrected age. Survival without major impairment was observed in 75%, 80%, and 100% of the survivors when rupture of membranes occurred at 14-19 weeks, 20-25 weeks, and 26-28 weeks, respectively. CONCLUSION: Expectant management of second-trimester PROM offers better perinatal and long-term survival than previously thought.
