Incontinence severity and major depression in incontinent women

OBJECTIVE: Research has shown an association between urinary incontinence and depression. Studies that use community-based samples and major depressive disorder diagnostic criteria are needed. The objective of this study was to estimate the prevalence of and factors associated with major depression in women with urinary incontinence. METHODS: We conducted an age-stratified postal survey of 6,000 women aged 30-90 years. Subjects were randomly selected from enrollees in a large health maintenance organization in Washington state. Main outcome measures were prevalence of current major depression and adjusted odds ratios for factors associated with major depression in women with urinary incontinence. RESULTS: The response rate was 64% (n = 3,536) after applying exclusion criteria. The prevalence of urinary incontinence was 42% (n = 1,458). The prevalence of major depression was 3.7% (n = 129), with 2.2% in those without incontinence versus 6.1% in those with incontinence. Among women with incontinence, major depression prevalence rates differed by incontinence severity (2.1% in mild, 5.7% in moderate, and 8.3% in severe) and incontinence type (4.7% in stress, 6.6% in urge/mixed). Obesity (odds ratio [OR] 2.3, 95% confidence interval [CI] 1.3-4.0), current smoking (OR 2.7, 95% CI 1.5-4.9), lower educational attainment (OR 2.0, 95% CI 1.2-3.3), moderate incontinence (OR 2.7, 95% CI 1.1-6.6), and severe incontinence (OR 3.8, 95% CI 1.6-9.1) were each associated with increased odds of major depression in women with urinary incontinence, controlling for age and medical comorbidity. Compared with women with incontinence alone, women with comorbid incontinence and major depression had significantly greater decrements in quality of life and functional status and increased incontinence symptom burden. CONCLUSION: Women with moderate-to-severe urinary incontinence should be screened for comorbid major depression and offered treatment if depression is present. LEVEL OF EVIDENCE: II-2.     

Vaginal delivery parameters and urinary incontinence: the Norwegian EPINCONT study

OBJECTIVE: The study was undertaken to investigate the effect of nine delivery parameters on urinary incontinence in later life. STUDY DESIGN: Incontinence data from the EPINCONT study were linked to the Medical Birth Registry of Norway. Effects of birth weight, gestational age, head circumference, breech delivery, injuries in the delivery channel, functional delivery disorders, forceps delivery, vacuum delivery, and epidural anesthesia were investigated. The study covered women younger than 65 years, who had had vaginal deliveries only (n=11,397). RESULTS: Statistically significant associations were observed between any incontinence and birth weight 4000 g or greater (odds ratio [OR] 1.1, 95% CI 1.0-1.2); moderate or severe incontinence and functional delivery disorders (OR 1.3, 95% CI 1.1-1.6); stress incontinence and high birth weight (OR 1.2, 95% CI 1.1-1.3) and epidural anesthesia (OR 1.2, 95% CI 1.0-1.5); and urge incontinence and head circumference 38 cm or larger (OR 1.8, 95% CI 1.0-3.3). CONCLUSION: The effects were too weak to explain a substantial part of the association between vaginal delivery and urinary incontinence, and statistically significant results may have incurred by chance.     

Predictors of urinary incontinence in a prospective cohort of postmenopausal women

OBJECTIVE: To prospectively assess risk factors associated with occurrence of urinary incontinence among postmenopausal women. METHODS: We followed up 1,017 postmenopausal health maintenance organization enrollees, aged 55 to 75 years, for 2 years. The primary outcome measures were any urinary incontinence and severe incontinence reported at 12- or 24-month follow-up visits. RESULTS: Baseline prevalence of any amount or frequency of urinary incontinence in the past year was 66%. Among the 345 women without incontinence at baseline, 65 (19%) at 1 year and 66 (19%) at 2 years reported any incontinence. Ninety-two of 672 (14%) and 96 of 672 (14%) women with incontinence at baseline reported no incontinence at years 1 and 2. In an adjusted multiple logistic regression model, independent predictors of any incontinence included white race (odds ratio [OR] 1.7, 95% confidence interval [CI] 1.1-2.6), vaginal estrogen cream (OR 2.0, CI 1.1-3.7), vaginal dryness (OR 1.6, CI 1.2-2.2), vaginal discharge (OR 1.5, CI 1.0-2.2), 6 or more lifetime urinary tract infections (OR 1.8, CI 1.2-2.6), and diabetic peripheral neuropathy (OR 1.7, CI 1.0-3.1). In adjusted models, predictors of severe incontinence were history of hysterectomy (OR 1.8, CI 1.1-2.7) and any vaginal symptom (OR 1.7, CI 1.0-2.8). CONCLUSION: A substantial proportion of incontinence-free postmenopausal women developed urinary incontinence during 2 years of follow-up. Because vaginal symptoms are associated with urinary incontinence, their relationship with other risk factors, including vaginal Escherichia coli colonization and vaginal estrogen cream use, warrant additional study. Similarly, diabetic peripheral neuropathy and hysterectomy associations suggest areas for future investigation. LEVEL OF EVIDENCE: II-2.     

Urinary tract infections in postmenopausal women: effect of hormone therapy and risk factors.

OBJECTIVE: To assess the effects of hormone therapy on urinary tract infection frequency and to examine potential risk factors. METHODS: We used data from the Heart and Estrogen/Progestin Replacement Study, a randomized, blinded trial of the effects of hormone therapy on coronary heart disease events among 2763 postmenopausal women aged 44-79 with established coronary heart disease. Participants were randomly assigned to 0.625 mg of conjugated estrogens plus 2.5 mg of medroxyprogesterone acetate or placebo and followed for a mean of 4.1 years. History of physician-diagnosed urinary tract infections and risk factors were assessed by self-report at baseline and each annual visit. RESULTS: Urinary tract infection frequency was higher in the group randomized to hormone treatment, although the difference was not statistically significant (odds ratio [OR] 1.16, 95% confidence interval [CI] 0.99, 1.37). Statistically significant risk factors for urinary tract infections in multivariable analysis included: women with diabetes on treatment (insulin OR 1.81, 95% CI 1.40, 2.34), oral medications OR 1.44, 95% CI 1.09, 1.90), poor health (OR 1.34, 95% CI 1.14, 1.57), childbirth (OR 1.38, 95% CI 1.00, 1.90), vaginal itching (OR 1.63, 95% CI 1.07, 2.50), vaginal dryness (OR 1.30, 95% CI 1.04, 1.67), and urge incontinence (OR 1.51, 95% CI 1.30, 1.75). Urinary tract infections in the previous year were strongly associated with a single urinary tract infection (OR 7.00, 95% CI 5.91, 8.29) as well as multiple urinary tract infections (OR 18.51, 95% CI 14.27, 24.02). CONCLUSIONS: Oral hormone therapy did not reduce frequency of urinary tract infections. Potentially modifiable risk factors in postmenopausal women are different from those in younger women, and include diabetes, vaginal symptoms, and urge incontinence.     

Anal incontinence after vaginal delivery: a five-year prospective cohort study

OBJECTIVE: The long-term prevalence of anal incontinence after vaginal delivery is unknown. The aim of the present study was to evaluate the prevalence of anal incontinence in primiparous women 5 years after their first delivery and to evaluate the influence of subsequent childbirth. METHODS: A total of 349 nulliparous women were prospectively followed up with questionnaires before pregnancy, at 5 and 9 months, and 5 years after delivery. A total of 242 women completed all questionnaires. Women with sphincter tear at their first delivery were compared with women without such injury. Risk factors for development of anal incontinence were also analyzed. RESULTS: Anal incontinence increased significantly during the study period. Among women with sphincter tears, 44% reported anal incontinence at 9 months and 53% at 5 years (P = .002). Twenty-five percent of women without a sphincter tear reported anal incontinence at 9 months and 32% had symptoms at 5 years (P < .001). Risk factors for anal incontinence at 5 years were age (odds ratio [OR] 1.1; 95% confidence interval [CI] 1.0-1.2), sphincter tear (OR 2.3; 95% CI 1.1-5.0), and subsequent childbirth (OR 2.4; 95% CI 1.1-5.6). As a predictor of anal incontinence at 5 years after the first delivery, anal incontinence at both 5 months (OR 3.8; 95% CI 2.0-7.3) and 9 months (OR 4.3; 95% CI 2.2-8.2) was identified. Among women with symptoms, the majority had infrequent incontinence to flatus, whereas fecal incontinence was rare. CONCLUSION: Anal incontinence among primiparous women increases over time and is affected by further childbirth. Anal incontinence at 9 months postpartum is an important predictor of persisting symptoms.     

Prevalence of anal incontinence in women with symptoms of urinary incontinence and genital prolapse

OBJECTIVE: To investigate risk factors and prevalence of anal incontinence among women with pelvic floor dysfunctions. METHODS: We evaluated 881 women with symptoms of urinary incontinence and/or genital prolapse. Each completed a bowel questionnaire and underwent a detailed medical, surgical, obstetric, and gynecologic history, and a pelvic examination. Additional testing, when indicated, included office cystometry or multichannel urodynamic evaluation. Multivariable analysis using logistic regression was used to test the overall significance of all variables significantly associated with anal incontinence, using univariate analysis. RESULTS: A total of 178 women had anal incontinence (20%). These patients were on average older, had a greater body mass index, and had larger birth weight infants than their anal-continent counterparts; 511 were diagnosed with urinary incontinence, and 122 (24%) also had anal incontinence. Women with urinary incontinence were more likely to report anal incontinence events than women continent of urine (24% versus 15%, P =.002). The following associations were found with anal incontinence: infant with birth weight 3800 g or greater (odds ratio [OR] 1.5, 95% confidence interval [CI] 1.1, 2.2), rectocele greater than grade 2 (OR 1.9, 95% CI 1.1, 3.3), urinary incontinence (OR 1.9, 95% CI 1.3, 2.8), hemorrhoidectomy (OR 2.7, 95% CI 1.1, 7.0), irritable bowel syndrome (OR 6.3, 95% CI 3.5, 11.5). CONCLUSION: Among women with symptoms of urinary incontinence and pelvic organ prolapse, the prevalence of anal incontinence was 20%. Urinary incontinence and severe rectocele were found to be associated with anal incontinence.     

Effect of raloxifene on urinary incontinence: a randomized controlled trial

OBJECTIVE: To estimate the effect of 3 years of treatment with raloxifene on urinary incontinence in postmenopausal women. METHODS: We used measures of urinary incontinence severity, frequency, and type in the Multiple Outcomes of Raloxifene trial, a multicenter randomized, controlled trial of women who were at least 2 years postmenopausal with osteoporosis. At 10 U.S. sites of this trial, 963 women randomly assigned to raloxifene or placebo completed questionnaires about incontinence at baseline and 3 years later. We analyzed the odds of worsening severity and frequency of incontinence and type of incontinence after 3 years of treatment with raloxifene. RESULTS: The mean age of our subjects was 68.3 +/- 7 years. After 3 years of treatment, there was no significant difference between raloxifene and placebo groups in urinary incontinence severity (multivariable odds ratio [OR] 1.02; 95% [CI] 0.78, 1.34). The majority of the women (60%) had no change in urinary incontinence episodes from baseline to year 3. The odds of worsening urinary incontinence severity after 3 years of raloxifene treatment were 1.05 (95% CI 0.75, 1.48). Similarly, the odds of developing new onset incontinence were 0.95 (95% CI 0.59, 1.52). Finally, raloxifene did not effect the odds of having stress (OR 1.01; 95% CI 0.71, 1.43) or urge (OR 1.20; 95% CI 0.86, 1.68) incontinence after 3 years of use. CONCLUSION: In postmenopausal women with osteoporosis, 3 years of treatment with raloxifene had no effect on urinary incontinence. LEVEL OF EVIDENCE: I     

Anal sphincter tears at vaginal delivery: risk factors and clinical outcome of primary repair.

OBJECTIVE: To determine risk factors for obstetric anal sphincter tears and to evaluate symptomatic outcome of primary repair. METHODS: Obstetric-procedure, maternal, and fetal data were registered in 845 consecutive vaginally delivered women. Risk factors for anal sphincter tears were calculated by multiple logistic regression. All 808 Swedish-speaking women who delivered vaginally were included in a questionnaire study regarding anal incontinence in relation to the delivery. Questionnaires were distributed within the first few days postpartum, and at 5 and 9 months postpartum. RESULTS: Six percent of the women had a clinically detected sphincter tear at delivery. Sphincter tears were associated with nulliparity (odds ratio [OR] 9.8, 95% confidence interval [CI] 3.6, 26.2), postmaturity (OR 2.5, 95% CI 1.0, 6.2), fundal pressure (OR 4.6 95% CI 2.3, 7.9), midline episiotomy (OR 5.5 95% CI 1.4,18.7), and fetal weight in intervals of 250 g (OR 1.3 95% CI 1.1, 1.6). Fifty-four percent of women with repaired sphincter tears suffered from fecal or gas incontinence or both at 5 months and 41% at 9 months. Most of the symptoms were infrequent and mild. CONCLUSION: Several risk factors for sphincter tear were identified. Sphincter tear at vaginal delivery is a serious complication, and it is frequently associated with anal incontinence. Special attention should be directed toward risk factors for this complication. Symptoms of anal incontinence should explicitly be sought at follow-up after delivery.     

Risk factors for wound infection following cesarean deliveries.

OBJECTIVE: To identify risk factors for early wound infection (diagnosed prior to discharge) following cesarean delivery. METHODS: A population-based study comparing women who have and have not developed a wound infection prior to discharge from Soroka University Medical Center, Ben Gurion University of the Negev, between 1988 and 2002. RESULTS: Of the 19,416 cesarean deliveries performed during the study period, 726 (3.7%) were followed by wound infection. Using a multivariable logistic regression model, the following risk factors were identified: obesity (odds ratio [OR] = 2.2; 95% confidence interval [CI], 1.6-3.1); hypertensive disorders (OR = 1.7; 95% CI, 1.4-2.1); premature rupture of membranes (OR = 1.5; 95% CI, 1.2-1.9); diabetes mellitus (OR = 1.4; 95% CI, 1.1-1.7); emergency cesarean delivery (OR = 1.3; 95% CI, 1.1-1.5); and twin delivery (OR = 1.6; 95% CI, 1.3-2.0). Combined obesity and diabetes (gestational and pregestational) increased the risk for wound infection 9.3-fold (95% CI, 4.5-19.2; P < .001). CONCLUSION: Independent risk factors for an early wound infection are obesity, diabetes, hypertension, premature rupture of membranes, emergency cesarean delivery, and twin delivery. Information regarding higher rates of wound infection should be provided to obese women undergoing cesarean delivery, especially when diabetes coexists.     

Risk factors for pelvic organ prolapse repair after hysterectomy

OBJECTIVE: To estimate the incidence and identify the risk factors for pelvic organ prolapse repair after hysterectomy. METHODS: We conducted a case-control study. We identified 6,214 women who underwent hysterectomy in our gynecology department from 1982 to 2002. Cases (n=114) were women who required pelvic organ prolapse surgery after hysterectomy from January 1982 through December 2005. Controls (n=236) were women randomly selected from the same cohort who did not require pelvic organ surgery during the same period. We performed a univariable and a multivariable analysis among 104 cases and 190 controls to identify the variables associated with prolapse repair after hysterectomy. RESULTS: The incidence of pelvic organ prolapse that required surgical correction after hysterectomy was 1.3 per 1,000 women-years. The risk of prolapse repair was 4.7 times higher in women whose initial hysterectomy was indicated by prolapse and 8.0 times higher if preoperative prolapse grade 2 or more was present. Risk factors included preoperative prolapse grade 2 or more (adjusted odds ratio [OR] 12.6, 95% confidence interval [CI] 4.6-34.7), previous pelvic organ prolapse or urinary incontinence surgery (adjusted OR 7.9, 95% CI 1.3-48.2), history of vaginal delivery (adjusted OR 5.0, 95% CI 1.3-19.7), and sexual activity (adjusted OR 6.2, 95% CI 2.7-14.5). Vaginal hysterectomy was not a risk factor when preoperative prolapse was taken into account (adjusted OR 0.7, 95% CI 0.4-1.1). CONCLUSION: Preoperative pelvic organ prolapse and other factors related to pelvic floor weakness were significantly associated with subsequent pelvic floor repair after hysterectomy. Vaginal hysterectomy was not a risk factor. LEVEL OF EVIDENCE: II.     

The prevalence and bothersomeness of lower urinary tract symptoms in women 40-60 years of age

AIM: To assess the prevalence and bothersomeness of lower urinary tract symptoms in women aged 4060 years. Study design. Ongoing longitudinal cohort study. METHODS: Four thousand women recruited on a random basis from the Civil Registration System, in one rural and one urban county in Denmark, were asked to fill in a self-administered, validated questionnaire on lower urinary tract symptoms. Logistic regression analysis was performed to assess the relationship between LUTS, bothersomeness, age, and county residency. Symptom scores and bother scores were compared in order to obtain a valid measure of lower urinary tract symptoms (LUTS). RESULTS: The prevalence of LUTS occurring more than weekly was 27.8% (95% CI: 26.2%-29.4%) and 16.1% (95% CI: 14.8-17.4) had urinary incontinence. The prevalence of stress incontinence increased from at 40 years up to the age of 55 years (OR=1.9 (95% CI: 1.3-2.7)) and declined thereafter. Irritative symptoms such as urge incontinence and urgency steadily escalated in an almost linear fashion with increasing age ((OR=2.7 (95% CI: 1.6-4.5) and OR=2.1 (95% CI: 1.5-2.8), respectively). Incontinence symptoms were the most bothersome. Age was positively associated with most LUTS, but not with bothersomeness. County residency was not associated with LUTS. CONCLUSION: Women aged 40-60 years frequently have bothersome lower urinary tract symptoms. Age, but not county residency, is an important factor associated with the occurrence of lower urinary tract symptoms in perimenopausal women. LUTS occurring more often than weekly seem to be the most appropriate single measure of LUTS.     

Is grandmultiparity an independent risk factor for adverse perinatal outcomes?

OBJECTIVE: To compare maternal and neonatal outcomes among grandmultiparous women to those of multiparous women 30 years or older. METHODS: A database of the vast majority of maternal and newborn hospital discharge records linked to birth/death certificates was queried to obtain information on all multiparous women with a singleton delivery in the state of California from January 1, 1997 through December 31, 1998. Maternal and neonatal pregnancy outcomes of grandmultiparous women were compared to multiparous women who were 30 years or older at the time of their last birth. RESULTS: The study population included 25,512 grandmultiparous and 265,060 multiparous women 30 years or older as controls. Grandmultiparous women were predominantly Hispanic (56%). After controlling for potential confounding factors, grandmultiparous women were at significantly higher risk for abruptio placentae (odds ratio OR: 1.3; 95% confidence intervals CI: 1.2-1.5), preterm delivery (OR: 1.3; 95% CI: 1.2-1.4), fetal macrosomia (OR: 1.5; 95% CI: 1.4-1.6), neonatal death (OR: 1.5; 95% CI: 1.3-1.8), postpartum hemorrhage (OR: 1.2; 95% CI: 1.1-1.3) and blood transfusion (OR: 1.5; 95% CI: 1.3-1.8). CONCLUSION: Grandmultiparous women had increased maternal and neonatal morbidity, and neonatal mortality even after controlling for confounders, suggesting a need for closer observation than regular multiparous patients during labor and delivery.     

Mode of delivery and fecal incontinence at midlife: a study of 2,640 women in the Gazel cohort

OBJECTIVE: To estimate obstetric risk factors of fecal incontinence among middle-aged women. METHODS: We conducted a mail survey of the Gazel cohort of volunteers for epidemiologic research. In 2000, a questionnaire on anal incontinence was mailed to 3,114 women who were then between the ages of 50 and 61 years; 2,640 (85%) women returned the completed questionnaire. Fecal incontinence was defined by involuntary loss of stool. Logistic regression was used to estimate the effect of obstetric and general risk factors. RESULTS: Prevalence of fecal incontinence in the past 12 months was 9.5% (250). Significant risk factors for fecal incontinence were completion of high school (adjusted odds ratio [OR] 1.5, 95% confidence interval [CI] 1.1-2.0), self-reported depression (OR 2.1, 95% CI 1.6-2.7), overweight or obesity measured by body mass index (BMI) (OR 1.5 for BMI of 25-30, 95% CI 1.1-2.0; OR 1.6 for BMI more than 30, 95% CI 1.1-2.5), surgery for urinary incontinence (OR 3.5, 95% CI 2.0-6.1), and anal surgery (OR 1.7, 95% CI 1.1-2.9). No obstetric variable (parity, mode of delivery, birth weight, episiotomy, or third-degree perineal tear) was significant. Prevalence of fecal incontinence was similar for nulliparous, primiparous, secundiparous, and multiparous women (11.3%, 9.0%, 9.0%, and 10.4%, respectively), and among parous women, it was similar for women with spontaneous vaginal, instrumental (at least one), or only cesarean deliveries (9.3%, 10.0%, and 6.6%, respectively). CONCLUSION: In our population of women in their 50s, fecal incontinence was not associated with either parity or mode of delivery.     

Stress urinary incontinence 4 years after the first delivery: a retrospective cohort survey

BACKGROUND: Our aim was to estimate the prevalence of stress urinary incontinence 4 years after the first delivery and analyze its risk factors. METHODS: A retrospective cohort survey was conducted in a French university hospital. The 669 primiparous women who delivered in our department in 1996 a singleton in a vertex position between 37 and 41 weeks of amenorrhea were included. A mailed questionnaire was sent 4 years after the indexed delivery. The main outcome measure was stress urinary incontinence 4 years after the first delivery. RESULTS: Three hundred and seven women replied, 274 had moved and 88 did not respond. Four years after the first delivery, prevalence of stress urinary incontinence was 29% (89/307). According to multiple logistic regression analysis, the independent risk factors were urine leakage before the first pregnancy [odds ratio (OR) 18.7; 95% confidence interval (CI) 3.6-96.4], urine leakage during the first pregnancy (OR 2.5; 95% CI 1.3-4.8), duration of first labor > or = 8 h (OR 3.1; 95% CI 1.7-5.7), mother's age > 30 years at the first delivery (OR 2.4; 95% CI 1.4-4.2) and cesarean section at the first delivery (OR 0.3; 95% CI 0.1-0.9). CONCLUSION: Our results suggest that stress urinary incontinence after pregnancy arises from a multifactorial condition. The main risk factors are: age, previous incontinence (before or during the first pregnancy), prolonged labor and vaginal delivery.     

Genetic and environmental influences on urinary incontinence: a Danish population-based twin study of middle-aged and elderly women

BACKGROUND: Familial clustering has been reported for urinary incontinence (stress and urge), but different etiologies for the two types of incontinence have been suggested. OBJECTIVE: The aim of this study was to estimate the relative influence of genetic and environmental factors on stress, urge, and mixed incontinence among elderly and middle-aged women. METHODS: This is a population-based classical twin study of 1168 female twin pairs [548 monozygotic (MZ) and 620 dizygotic (DZ)] from a middle-aged (46-68 years) and an old (70-94 years) cohort identified in the Danish Twin Registry. Urinary incontinence was assessed with the help of two validated questions identifying stress and urge incontinence in interviews. RESULTS: For urge incontinence, the tetrachoric correlation was significantly higher for MZ twins, compared to that for DZ twin pairs in both middle-aged [0.51 (95% CI: 0.26-0.71) versus -0.22 (95% CI: -0.59-0.18)] and elderly [0.50 (95% CI: 0.27-0.68) versus 0.28 (95% CI: 0.02-0.42)], indicating genetic effects. The heritability of urge incontinence was 42% (95% CI: 16-63%) among middle-aged women and 49% (95% CI: 29-65%) among the elderly. Moreover, mixed incontinence had a substantial genetic component. The role of genetic factors was less clear in stress incontinence. CONCLUSIONS: Genetic factors play a substantial role in the development of urge and mixed incontinence, whereas the role of genetic factors in stress incontinence is less prominent.     

Early discharge revisited: problems encountered with the home visit follow-up after the liberalization of eligibility criteria

Objective.?To compare maternal and neonatal outcomes among grandmultiparous women to those of multiparous women 30 years or older.

Methods.?A database of the vast majority of maternal and newborn hospital discharge records linked to birth/death certificates was queried to obtain information on all multiparous women with a singleton delivery in the state of California from January 1, 1997 through December 31, 1998. Maternal and neonatal pregnancy outcomes of grandmultiparous women were compared to multiparous women who were 30 years or older at the time of their last birth.

Results.?The study population included 25,512 grandmultiparous and 265,060 multiparous women 30 years or older as controls. Grandmultiparous women were predominantly Hispanic (56%). After controlling for potential confounding factors, grandmultiparous women were at significantly higher risk for abruptio placentae (odds ratio OR: 1.3; 95% confidence intervals CI: 1.2–1.5), preterm delivery (OR: 1.3; 95% CI: 1.2–1.4), fetal macrosomia (OR: 1.5; 95% CI: 1.4–1.6), neonatal death (OR: 1.5; 95% CI: 1.3–1.8), postpartum hemorrhage (OR: 1.2; 95% CI: 1.1–1.3) and blood transfusion (OR: 1.5; 95% CI: 1.3–1.8).

Conclusion.?Grandmultiparous women had increased maternal and neonatal morbidity, and neonatal mortality even after controlling for confounders, suggesting a need for closer observation than regular multiparous patients during labor and delivery.     

Urinary incontinence during pregnancy

OBJECTIVE: To investigate incidence and prevalence of urinary incontinence during pregnancy and associated risk factors. METHODS: The data collection was conducted as part of the Norwegian Mother and Child Cohort Study at the Norwegian Institute of Public Health. We present questionnaire data about urinary incontinence obtained from 43,279 women (response rate 45%) by week 30. We report data on any incontinence, in addition to type, frequency, and amount of incontinence. Potential risk factors were investigated by logistic regression analyses. RESULTS: The prevalence of incontinence increased from 26% before pregnancy to 58% in week 30. The corresponding figures for nulliparous women were 15% and 48%, and for parous women 35% and 67%. The cumulative incidence was 46%. Stress urinary incontinence was the most common type of incontinence in week 30 of pregnancy, experienced by 31% of nulliparous and 42% of parous women. The majority of pregnant women had leakage less than once per week and droplets only, both before and during pregnancy. Parity was a strong and significant risk factor for incontinence in adjusted analyses both before pregnancy (odds ratio [OR] 2.5, 95% confidence interval [CI] 2.4-2.7 for primiparous and OR 3.3, 95% CI 3.1-3.5 for multiparous women) and during pregnancy (ORs 2.0, 95% CI 1.9-2.1 and 2.1, 95% CI 2.0-2.2, respectively). Age and body mass index were weaker, but still statistically significant, risk factors. CONCLUSION: The prevalence of urinary incontinence increases substantially during pregnancy. Incontinence both before and during pregnancy seems to be associated with parity, age, and body mass index. LEVEL OF EVIDENCE: II.     

Hospitalizations with respiratory illness among pregnant women during influenza season

OBJECTIVE: To examine hospitalizations with respiratory illness among pregnant women in the United States during periods of influenza activity. METHODS: Data were obtained from the Healthcare Cost and Utilization Project National Inpatient Sample (NIS), the largest publicly available all-payer hospital discharge database. Hospitalizations for respiratory illness and pregnancy were classified with International Classification of Diseases, 9th Revision, Clinical Modification codes. Analyses were stratified by delivery status. Discharge characteristics, length of stay, and complications of delivery among hospitalized pregnant women with and those without respiratory illness were compared. RESULTS: During the 1998-2002 influenza seasons, 3.4 per 1,000 hospitalizations of pregnant women included diagnoses of respiratory illness. Characteristics of pregnancy hospitalizations associated with higher odds of respiratory illness were presence of a high-risk condition for which influenza vaccination is recommended (adjusted odds ratio [OR] 3.2, 95% confidence interval [CI] 3.0-3.5 and OR 6.0, 95% CI 5.2-6.9 for nondelivery and delivery, respectively), Medicaid/Medicare as primary expected payer of care (OR 1.2, 95% CI 1.1-1.3 and OR 1.9, 95% CI 1.7-2.2 for nondelivery and delivery, respectively), and hospitalization in a rural area (OR 1.2, 95% CI 1.1-1.4 for nondelivery). During influenza season, hospitalized pregnant women with respiratory illness had significantly longer lengths of stay and higher odds of delivery complications than hospitalized pregnant women without respiratory illness. CONCLUSION: Hospitalizations with respiratory illness among pregnant women during influenza season are associated with increased burden for patients and the health care system. Intervention efforts to decrease influenza-related respiratory morbidity among pregnant women should be encouraged. LEVEL OF EVIDENCE: III.     

Polymorphisms in the fibrinolytic pathway genes and the risk of recurrent spontaneous abortion

Impaired fibrinolytic activity is implicated in the pathogenesis of recurrent spontaneous abortion (RSA). This case-control study assessed the prevalence of polymorphisms in fibrinolytic system genes in RSA. Cases comprised 202 Sinhalese women who had experienced at least two first-trimester spontaneous abortions and had no living children; controls were 202 women with no history of spontaneous abortion and two or more living children. The groups were matched for age and ethnicity. DNA was genotyped using the Sequenom MassARRAY system. The PLAUR rs4251923 A (OR 95% CI 2.3 [1.3 to 4.0]), SERBP2 rs6098 A (OR 95% CI 1.4 [1.1 to 1.9]) and SERBP2 rs6103 C alleles (OR 95% CI 1.4 [1.1 to 1.9]) were increased in the RSA group compared with controls. The prevalence of PLAUR rs4251923/ SERBP2 rs6098/ SERBP2 rs6103 GG/AA/CC (OR 95% CI 2.4 [1.2 to 4.9], GA/GA/GC(OR 95% CI 3.9 [1.3 to 11.2]), GA/AA/CC (OR 95% CI 2.9 [1.0 to 8.6] and GA/GG/GG (OR 95% CI 21.3 [1.1 to 410.3]) genotypes were also increased in cases. Polymorphisms in the fibrinolytic system genes are associated with RSA in Sinhalese women. These likely impair implantation.
