Abstract
IMPORTANCE Understanding overactive bladder (OAB) during pregnancy and postpartum may increase our knowledge of pathophysiology. OBJECTIVES The purpose of this study was to understand the prevalence and severity of OAB during pregnancy through 1 year postpartum as well as the associated factors. STUDY DESIGN This is a secondary analysis of a prospective cohort study evaluating primiparous women with a singleton term vaginal delivery assessed at the third trimester, 8 weeks postpartum, and 1 year postpartum. Overactive bladder was defined as urinary urgency plus nocturia or frequency, or urgency urinary incontinence (UUI). Overactive bladder severity was defined using average visual analog scores (0-100) from OAB symptoms on the Epidemiology of Prolapse and Incontinence Questionnaire. We evaluated associations with OAB at each time point using logistic regression. RESULTS Among 579 participants, mean age was 29 years. Overactive bladder prevalence was higher at 8 weeks postpartum (23%) than at the third trimester (18%, P = 0.03) and 1 year postpartum (19%, P = 0.03). Overactive bladder severity was higher at the third trimester (42.2) than at 8 weeks postpartum (23.3, P = 0.008), but not at 1 year postpartum (29.1, P = 0.1). In those with OAB, UUI severity was higher at 1 year postpartum compared with that at the third trimester ( P = 0.02). Younger age was associated with third trimester OAB. At 8 weeks postpartum, OAB was associated with older age, urinary tract infection after delivery, birth weight ≥3,500 g, and third trimester OAB. At 1 year postpartum, OAB was associated with birth weight ≥3,500 g and third trimester OAB. CONCLUSIONS Overactive bladder affects 1 in 5 primiparous women during pregnancy or after vaginal delivery. The increased severity of UUI postpartum and the association between higher birth weight and OAB postpartum suggest an effect of delivery.

Abstract
Background The prevalence of pelvic organ prolapse is varied in different countries. For validating the results of numerous studies on the prevalence of Pelvic organ prolapse in the world, a meta-analysis study seems necessary to provide an accurate and valid prevalence for planners and researchers in this field. Therefore, we aimed to investigate the worldwide prevalence of pelvic organ prolapse using the meta-analysis method. Methods By using valid keywords, searching was done in ISI Web of Science, PubMed, Scopus, and Medline databases, and 22 articles were selected based on inclusion criteria between 2009 and 2021. The quality of articles was checked using The Joanna Briggs Institute (JBI) checklist. Meta-analysis was performed on collected data using Comprehensive Meta-Analysis Software (CMA, Version 2). Meta-analysis of data was done with a random-effects model. The heterogeneity of the study was checked using the I2 index. Publication bias was assessed by the Egger test and funnel graph. Results The overall prevalence of included studies was 30.9% (95% confidence interval: 24.4-38.2%), (P<0.001, heterogeneity I2=99.8%). Meta-analysis of subgroups in studies that used a questionnaire to estimate the prevalence rate showed the prevalence was 25.0% and, in the studies, used the physical examination was 41.8%. Conclusion Studies carried out in different parts of the world have examined the prevalence of pelvic organ prolapse using different tools. Since some cases are asymptomatic, especially in the low stage of prolapse, physical examination of pelvic organ prolapse should be considered an essential tool in evaluating pelvic organ prolapse.

Abstract
Objectives Approximately 75% of women weigh more at 1-year postpartum than pre-pregnancy. More than 47% retain >10 lbs at 1-year postpartum, which is associated with adverse health outcomes for mother and child. Disturbed sleep may contribute to risk of postpartum weight retention (PWR) as short sleep duration is associated with increased risk of obesity. Thus, we investigated whether night-time sleep duration is associated with risk for excessive PWR. We also explored night-time sleep duration and change in postpartum waist circumference. Methods This is an ancillary analysis from a prospective cohort study. Participants were healthy primiparous adults with a singleton birth. Excessive PWR at 1-year postpartum was defined as ≥7% of pre-pregnancy weight. Log-binomial and linear regression assessed associations between night-time sleep duration at 6 months postpartum and PWR at 1-year postpartum. Linear regression assessed the association between night-time sleep duration and change in postpartum waist circumference. Results Mean age of participants (N = 467) was 29.51 (SD ± 4.78) years. Night-time sleep duration by actigraphy or self-report was not associated with risk for excessive PWR (risk ratio 0.96, [95%CI 0.87-1.06]; risk ratio 0.95 [95%CI 0.83-1.07], respectively) or change in waist circumference. Conclusion Night-time sleep duration at 6 months postpartum was not associated with PWR at 1-year postpartum. Mixed findings among our results and previous research could be due to our focus on night-time sleep, and differences in sleep measurement methods and timeframes across studies. More comprehensively assessing sleep, including multiple sleep dimensions, may help advance our understanding of potential links between sleep and PWR. Trial Registration The parent study, Motherhood and Pelvic Health (MAP Study), is registered at https://clinicaltrials.gov/ct2/show/NCT02512016, NCT02512016.

Abstract
IMPORTANCE Evidence suggests that genital hiatus (GH) enlargement precedes pelvic organ prolapse development remote from delivery. However, the association of postpartum GH enlargement and prolapse is unknown. OBJECTIVE The aim of this study was to determine the association between enlarged GH at 8 weeks postpartum and prolapse 1 year after first vaginal delivery. STUDY DESIGN This is a secondary analysis of the Motherhood and Pelvic Health study, a prospective cohort of women after their first vaginal delivery. Enlarged GH was defined as ≥4 cm. Prolapse was defined as Pelvic Organ Prolapse Quantification points Ba, Bp, or C at or beyond the hymen. Kaplan-Meier analysis and proportional hazards modeling were used to analyze the association between enlarged GH at 8 weeks postpartum and prolapse at 1 year postpartum. Diagnostic test characteristics of enlarged GH were calculated. RESULTS Five hundred eighty women were included. At 1 year postpartum, the prevalence of prolapse was 3 times higher in women with, versus without, an enlarged GH at 8 weeks postpartum (16% vs 5%, P < 0.001). This was confirmed in a Cox proportional hazards model while adjusting for age, body mass index, and early postpartum prolapse (adjusted hazard ratio, 3.3; 95% confidence interval, 1.85-6.06; P < 0.001). The diagnostic properties of postpartum GH to predict prolapse at 1 year are as follows: sensitivity, 0.63; specificity, 0.67; positive predictive value, 0.17; and negative predictive value, 0.95. CONCLUSIONS Women with an enlarged GH at 8 weeks postpartum have a 3.3-fold increased risk of prolapse at 1 year. As a screening tool, GH <4 cm at 8 weeks postpartum has high negative predictive value.

Abstract
We evaluated the association between sedentary time and pelvic floor support in primiparas delivered vaginally. The 532 participants (29.2 ± 4.9 years) wore wrist accelerometers 6 months postpartum to assess sedentary time, light physical activity (LPA) and moderate to vigorous physical activity (MVPA). We assessed pelvic floor support 1 year postpartum, considered worse if vaginal walls or apex prolapsed to or beyond the hymen. We used multivariable isotemporal substitution analyses to determine the prevalence of worse support when replacing sedentary time with equal time spent in either LPA or MVPA. In 1 year, 9.4% demonstrated worse pelvic floor support. Decreasing sedentary time by 30 min/day with a concomitant increase in MVPA, controlling for LPA, was associated with increased prevalence of worse support (PR 1.43 (95% CI 1.15, 1.77), P < 0.01). Decreasing the sedentary time by 30 min/day with a concomitant increase in LPA, controlling for MVPA, was not significant (PR 0.89 (95% CI 0.80, 0.99), P = 0.04, > pre-set alpha of 0.02). Increasing MVPA while decreasing LPA, controlling for sedentary time, also increased the prevalence of worse support (PR 1.66 (95% CI 1.28, 2.16), P < 0.001). In conclusion, decreasing sedentary time increased the prevalence of worse pelvic floor support when replaced by MVPA, but not LPA.

Abstract
BACKGROUND AND AIMS The present study aimed to analyze the effects of factors on cystocele and the Green classification. MATERIALS AND METHODS We conducted a cross-sectional study on 357 primiparous women examined at our hospital from January 2019 to May 2021. The following data were recorded: maternal characteristics, neonatal characteristics, and factors of childbirth. It was added to the multivariate logistic regression model to determine the independent predictors of the cystocele and the Green classification. RESULTS A total of 242 women had cystocele, including 71 women with Green type I cystocele, 134 women with Green type II cystocele, and 37 women with Green type III cystocele. In multivariate logistic regression analysis, body mass index (BMI) at delivery was associated with cystocele, while BMI at delivery and the second stage of labor (SSL) > 1 h were independently with the distance from the symphysis pubis to the bladder neck (SPBN) abnormal (P < 0.05). BMI at examination was associated with the large retrovesical angle (RVA) (P < 0.05). BMI at delivery and the fetal right occiput anterior position (ROA) were independently associated with the distance from the symphysis pubis to the posterior wall of the bladder (SPBP) abnormal (P < 0.05), while epidural anesthesia (EDA) was the protective factor (P < 0.05). CONCLUSION Primipara women should strive to avoid exposure to modifiable risk factors such as controlling weight during pregnancy, reducing weight after delivery, and shortening SSL to reduce the occurrence of cystocele.

Abstract
IMPORTANCE Obesity may be a modifiable risk factor for pelvic floor disorders. OBJECTIVES The objective of this study is to determine associations between weight, weight changes, and cumulative exposure to excess body mass index (BMI) from prepregnancy to 1 year postpartum on pelvic floor support and symptoms 1 year after first vaginal birth. STUDY DESIGN In 645 primiparous women who gave birth vaginally, we assessed anatomic pelvic floor support, pelvic floor symptoms and BMI at the third trimester, 5 - 10 weeks, and 1 year postpartum; we also assessed BMI prepregnancy and predelivery. Using multivariable models, we determined associations between pelvic floor outcomes 1 year postpartum and BMI quartiles at different timepoints, gestational weight gain, and postpartum weight retention. We evaluated associations between stress urinary incontinence (SUI) and moderate/severe urinary incontinence (UI) 1 year postpartum and cumulative excess BMI from prepregnancy to 1-year postpartum (BMI1year). RESULTS Body mass index was not associated with anatomic support, composite symptom burden, overactive bladder, anal incontinence, or constipation at any timepoint. Gestational weight gain and postpartum weight retention were not associated with any 1-year outcome. Body mass index at every timepoint was positively associated with SUI and moderate/severe UI; BMI1year was most predictive. Cumulative excess BMI was positively associated with SUI and moderate/severe UI but only slightly more predictive of these outcomes than BMI1year alone. CONCLUSIONS Body mass index over the pregnancy trajectory was not associated with outcomes other than UI. The small advantage of cumulative exposure to excess BMI over BMI1year in predicting SUI and moderate/severe UI suggests that BMI1year adequately captures risk of these 1-year outcomes.

Abstract
INTRODUCTION AND HYPOTHESIS To evaluate the effect of the second stage of labor (SSL) lasting > 2 h on pelvic floor function. METHODS This single-center prospective cohort study included primiparous women with SSL > 2 h treated at Tongji Hospital between January 2018 and December 2019 (case group). A matched group of women with similar newborn weight and SSL < 2 h were recruited simultaneously (control group). Stress urinary incontinence (SUI) and pelvic floor muscle (PFM) characteristics were measured at 6 weeks, 6 months, and finally 1 year postpartum. RESULTS A total of 63 pairs of primiparous women completed 1-year follow-up. The incidence of SUI in the case group was significantly higher than that in the control group at 6 weeks postpartum (P = 0.020); however, the differences were not significant at 1 year postpartum (P=1.00). PFM endurance was significantly lower in the case group at 6 weeks (P = 0.000), 6 months (P = 0.000), and 1 year (P = 0.011) after childbirth. There was no difference in PFM strength between the two groups. The maximal voluntary contraction (MVC) of PFM was significantly lower in the case group at 6 weeks postpartum (P = 0.007), but the differences were not significant at 1 year postpartum (P = 0.197). PFM endurance and MVC were higher at 1 year than at 6 weeks postpartum in both groups. CONCLUSIONS The SSL > 2 h increased the incidence of SUI at 6 weeks postpartum and decreased PFM endurance for 1 year.

Abstract
Little is known about early postpartum physical activity (PA). OBJECTIVES We aimed to describe PA amount and types and compare moderate-vigorous PA (MVPA) at 12-25 (T1) and 33-46 days (T2) postpartum. DESIGN Cross-sectional study. METHODS Participants, primiparas delivered vaginally, wore wrist accelerometers and completed questionnaires. Median and interquartile range (IQR) describe minutes/day of PA intensities in total minutes, 5- and 10-minute bouts. Wilcoxon Signed Rank test compared MVPA. RESULTS 577 (age: 28.3 (SD: 5.1)) had accelerometry or questionnaire at either time-point. 405 had accelerometry at both time-points. Median (IQR) total minutes/day for light, moderate, vigorous and MVPA were 295.8 (256.1-331.7), 54.6 (40-72.7), 0.4 (0.2-0.8), and 55.5 (40.4-74.3), respectively, at T1 and 329 (289.4-367.1), 63.6 (46.9-82.2), 0.6 (0.3-1.3), and 64.5 (47-84.8), respectively, at T2. Median (IQR) minutes/day for MVPA in 5- and 10-minute bouts were 1.6 (0-5.5) and 0 (0-3.8) at T1, and 3 (0-9.2) and 0 (0-5.5) at T2. At T1, 75% (406/541) and at T2, 72.4% (397/548) reported non-impact activities. At T1, 4% and at T2, 13% reported impact/straining activities. MVPA was greater at T2 than T1 (p < 0.0001) with medians (IQR) of: total: 64.7 (47-84.6) vs 56.5 (41-74.9) minutes; 5-minute bouts: 3 (0-9.8) vs 1.7 (0-5.6) minutes; and 10-minute bouts: 1.3(0-6) vs 0(0-3.8) minutes. CONCLUSIONS Women had high daily MVPA, though MVPA in bouts remained low. Significant increases in MVPA from T1 to T2 were small, few women reported impact/straining activities. Realistic return to pre-pregnancy PA levels should recognize the relative lack of sustained/strenuous activity in early postpartum.

Abstract
Objectives: To describe change in trunk flexor endurance and intra-abdominal pressure (IAP) associated with trunk flexor assessment and explore factors associated with change in trunk flexor endurance during the first postpartum year.Design: Ancillary analysis of an ongoing prospective cohort study.Methods: Participants (N = 282) were primiparous women delivered vaginally. They completed trunk flexor endurance testing while assessing IAP, body habitus measures (body mass index, waist circumference, and body composition), and questionnaires 5-10 weeks and 11-15 months postpartum. We investigated change in trunk flexor endurance by quartile of improvement and factors associated with improvement (Q4 vs. Q1-Q3) using multivariable models, adjusted for baseline endurance.Results: Mean age was 28 ± 5 years. The median (IQR) trunk flexor hold time increased from early to late postpartum (129/IQR = 68, 217 vs 148/IQR = 80, 265 seconds, p = .01) and mean (SD) IAP decreased (55/SD = 13 vs 48/SD = 14 cmH20, p < .0001). The most improved group (Q4) increased endurance time by 176 seconds (95% CI = 103, 254), were less likely to be Hispanic, more likely to be older, more educated, and have lower measures of body habitus than women in Q1-Q3. Conclusion: Trunk flexor endurance increased and IAP decreased over one year postpartum. Lower body habitus and higher age early postpartum predicted greatest improvement in trunk flexor endurance at 1 year.

Developing a web-based toolkit for new mothers about postpartum pelvic floor health in collaboration with a professional medical association. J Med Libr Assoc 2021; 109:667-671. [PMID: 34858099 PMCID: PMC8608176 DOI: 10.5195/jmla.2021.1078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/30/2022] Open
Abstract
Background: Few electronic resources are available for new mothers with concerns about changes in their pelvic floor following childbirth. Patients may struggle when seeking authoritative information regarding pelvic floor conditions online given the sensitivity of the topic as well as the inadvertent connection to obscene or demeaning content found online. A health sciences librarian partnered with the Motherhood and Pelvic Health Study, an interdisciplinary research group, to provide expert searching skills for a particularly challenging health condition that patients struggle to find useful information on. Case Presentation: A custom rubric was developed to evaluate existing information products, which included criteria for cultural sensitivity, conflicts of interest, and other red flags. This evaluation process enabled the research team to identify top-tier evidence-based materials that were culturally congruent. This collaborative evaluation process led to the creation of a web-based toolkit resource for new mothers concerned about changes in their pelvic floor. The toolkit connects women to pertinent information on a national health organization's patient portal, supplemented by videos created by the team to serve as models of communication for women and health care providers. Conclusion: When developing a web-based resource, health sciences libraries can partner with research teams to find, evaluate, and disseminate information. Culturally congruent toolkits such as this one can improve access to health information and lead to improved health outcomes. To ensure that the information highlighted in toolkits is both culturally congruent and authoritative, research teams should form advisory committees and partner with relevant professional medical associations.

Abstract
OBJECTIVE To estimate the association between habitus measures and pelvic floor support and symptoms in primiparous women 1 year after term vaginal delivery. METHODS In this cross-sectional study including women enrolled at seven academic and community sites, we assessed pelvic floor support, weight, height, waist circumference, and percent fat using air displacement plethysmography and participants completed questionnaires, all at one year postpartum. We tested the association of quintiles of habitus measure, including body mass index (BMI), waist circumference, percent body fat, and waist/height ratio, with the primary outcomes: anatomic support, dichotomized as maximal vaginal descent less than 0 cm (better support) compared with 0 cm or more (worse support) per the pelvic organ prolapse quantification examination and symptom burden (positive with bothersome symptoms in two or more of six symptom domains), and on five secondary outcomes. The sample size provides 90% power to detect odds ratios (ORs) of 1.78 or greater between women at mean compared with mean+1 SD of habitus measure. RESULTS Of 592 participants, 55 (9.3%) demonstrated worse support and 321 (54.2%) symptom burden. In multivariable analyses, habitus measures were not significantly associated with anatomic support or, except for the highest waist/height ratio quintile, with symptom burden. Compared with women in the first quintile of each habitus measure, those in most higher quintiles demonstrated elevated odds of moderate to severe urinary incontinence (UI); increased odds for stress urinary incontinence (SUI) were mainly limited to the highest quintile. After adjusting for percent body fat, the increased odds for BMI on SUI (OR 2.47, 95% CI 1.43-4.28) were no longer significant (OR 1.38, 95% CI 0.54, 3.51). CONCLUSION Habitus in primiparous patients at 1 year postpartum was not associated with anatomic support or symptom burden. Habitus was more associated with moderate to severe UI than mild UI. The association of higher BMI with SUI was attenuated by fitness, reflected by fat percentage.

Abstract
OBJECTIVES The objectives of this study were to describe trajectories of pelvic floor symptoms and support from the third trimester to 1 year postpartum in primiparous women after vaginal delivery and to explore factors associated with their resolution between 8 weeks postpartum and 1 year postpartum. METHODS Five hundred ninety-seven nulliparous women 18 years or older who gave birth vaginally at term completed the Epidemiology of Prolapse and Incontinence Questionnaire and the Pelvic Organ Prolapse Quantification examination at the third trimester, 8 weeks postpartum, and 1 year postpartum. RESULTS At 1 year postpartum, 41%, 32%, and 23% of participants reported stress urinary incontinence, nocturia, and flatus incontinence, respectively, and 9% demonstrated maximal vaginal descent (MVD) ≥ 0 cm. For more common symptoms, incidence rates between the third trimester and 8 weeks postpartum ranged from 6% for urinary frequency to 22% for difficult bowel movements, and resolution rates between 8 weeks postpartum and 1 year postpartum ranged from 23% for stress urinary incontinence to 73% for pain. Between the third trimester and 8 weeks postpartum, 13% demonstrated de novo MVD ≥ 0 cm. For most symptoms, the presence of the same symptom before delivery decreased the probability of resolution between 8 weeks postpartum and 1 year. However, the sensitivities of predelivery vaginal bulge and MVD of 0 cm or greater for those outcomes at 1 year postpartum was overall low (10-12%). CONCLUSIONS One year postpartum, urinary and bowel symptoms are common in primiparous women who gave birth vaginally. A substantial portion of this burden is represented by symptoms present before delivery, while most of the prevalence of worse anatomic support is accounted for by de novo changes after delivery.

Abstract
OBJECTIVES This study aimed to describe and compare pelvic floor symptoms and symptom burden between nulliparous Hispanic and non-Hispanic white women in the third trimester of pregnancy and to determine, in women with stress urinary incontinence (SUI), whether bother differs between groups, adjusted for UI severity. METHODS In this cross-sectional analysis, participants completed the Epidemiology of Prolapse and Incontinence and Incontinence Severity Index questionnaires. We compared differences in symptom domains between groups using logistic regression and tested the effect of ethnicity on bother in women with SUI using linear regression. RESULTS The sample comprised 418 non-Hispanic white and 154 Hispanic women. Prevalence rates of symptom domains ranged from 5.0% and 7.1% for pelvic organ prolapse to 95.2% and 94.2% for overactive bladder in non-Hispanic white and Hispanic women, respectively. After adjusting age, height, weight, education, physical activity, and gestational age, non-Hispanic whites had 2.37-fold increased odds (95% confidence interval, 1.44-3.92) for defecatory dysfunction and had nonsignificant increases in other symptom domains. Non-Hispanic whites were more likely to endorse symptoms in 3 or more domains than Hispanic women (58.9% vs 40.3%, respectively; P = 0.0001). Given the same UI severity (Incontinence Severity Index), Hispanic women with SUI reported 7.5 points greater bother (Epidemiology of Prolapse and Incontinence) than non-Hispanic white women (P = 0.07). CONCLUSIONS After adjustment, we found few differences in the prevalence of pelvic floor symptom domains between Hispanic and non-Hispanic white women, apart from defecatory dysfunction. If differences by ethnicity in other pelvic floor symptoms exist, they do not seem to originate during the first pregnancy.

Abstract
OBJECTIVE The aim of the study was to determine whether oxytocin for induction or augmentation of labor impacts the incidence or persistence of pelvic floor symptoms and support 5 to 10 weeks after first vaginal delivery. METHODS Participants in this prospective cohort study were nulliparous women 18 years or older that delivered vaginally at 37 weeks gestation or more and completed the Epidemiology of Prolapse and Incontinence Questionnaire (EPIQ) and the Pelvic Organ Prolapse Quantification examination in third trimester and 5 to 10 weeks postpartum. We compared the incidence and persistence of symptomatic EPIQ domains and worse vaginal support (maximal vaginal descent ≥0 cm) between women who received oxytocin with those that did not (with or without prostaglandin or mechanical methods in both groups). We performed modified binomial regression to calculate adjusted relative risks of each outcome with 95% confidence intervals. RESULTS The mean (SD) age of the 722 participants was 28.3 (5.2) years; 20% were Hispanic. There were no significant differences according to oxytocin exposure in either incidence or persistence of symptomatic EPIQ domains or worse vaginal support. We found similar results in sensitivity analyses comparing women who received oxytocin as the sole pharmacologic agent to women who received no pharmacologic agent. After adjusting for demographic and obstetric factors associated with incidence and persistence of symptoms and support, oxytocin exposure continued to have no effect. CONCLUSIONS Oxytocin during labor does not significantly increase the risks for the incidence or persistence of pelvic floor symptoms or worse vaginal support in the early postpartum period, although power for less frequent outcomes was limited.

Early postpartum physical activity and pelvic floor support and symptoms 1 year postpartum. Am J Obstet Gynecol 2021; 224:193.e1-193.e19.

Abstract
BACKGROUND Risks of pelvic organ prolapse and urinary incontinence increase after the first vaginal delivery. During the early postpartum period, a time of active regeneration and healing of the pelvic floor, women may be particularly vulnerable to greater pelvic floor loading. OBJECTIVE This prospective cohort study aimed to determine whether objectively measured moderate to vigorous physical activity in the early postpartum period predicts pelvic floor support and symptoms 1 year after the first vaginal birth. STUDY DESIGN We enrolled nulliparous women in the third trimester, later excluding those who had a cesarean or preterm delivery. Participants wore triaxial wrist accelerometers at 2 to 3 weeks and 5 to 6 weeks postpartum for ≥4 days. Primary outcomes, assessed 1 year postpartum, included (1) pelvic floor support on Pelvic Organ Prolapse Quantification examination, dichotomized as maximal vaginal descent of <0 cm (better support) vs ≥0 cm (worse support); and (2) pelvic floor symptom burden, considered positive with report of ≥1 bothersome symptom in ≥2 of 6 domains, assessed using the Epidemiology of Prolapse and Incontinence Questionnaire. The primary predictor was average daily moderate to vigorous physical activity. Because we could not eliminate women with pelvic floor changes before pregnancy, we modeled prevalence, rather than risk, ratios for each outcome using modified Poisson regression. RESULTS Of 825 participants eligible after delivery, 611 completed accelerometry and 1-year follow-up; 562 completed in-person visits, and 609 completed questionnaires. The mean age was 28.9 years (standard deviation, 5.01). The mean for moderate to vigorous physical activity measured in minutes per day was 57.3 (standard deviation, 25.4) and 68.1 (standard deviation, 28.9) at 2 to 3 weeks and 5 to 6 weeks, respectively. One year postpartum, 53 of 562 participants (9.4%) demonstrated worse vaginal support and 330 of 609 participants (54.2%) met criteria for pelvic floor symptom burden. In addition, 324 (53.1%), 284 (46.6%), 144 (23.6%), and 25 (4.1%) reported secondary outcomes of stress urinary incontinence, overactive bladder, anal incontinence, and constipation, respectively, and 264 (43.4%), 250 (41.0%), and 89 (14.6%) reported no, mild, or moderate to severe urinary incontinence, respectively. The relationship between moderate to vigorous physical activity and outcomes was not linear. On the basis of plots, we grouped quintiles of moderate to vigorous physical activity into 3 categories: first and second quintiles combined, third and fourth quintiles combined, and fifth quintile. In final multivariable models, compared with women in moderate to vigorous physical activity quintiles 3 and 4, those in the lower 2 (prevalence ratio, 0.55; 95% confidence interval, 0.31-1.00) and upper quintile (prevalence ratio, 0.70; 95% confidence interval, 0.35-1.38)) trended toward lower prevalence of worse support. However, we observed the reverse for symptom burden: compared with women in quintiles 3 and 4, those in the lower 2 (prevalence ratio, 1.20; 95% confidence interval, 1.02-1.41) and upper quintile prevalence ratio 1.34 (95% confidence interval, 1.11-1.61) demonstrated higher prevalence of symptom burden. Moderate to vigorous physical activity did not predict any of the secondary outcomes. The presence of a delivery factor with potential to increase risk for levator ani muscle injury did not modify the effect of moderate to vigorous physical activity on outcomes. CONCLUSION Except for support, which was worse in women with moderately high levels of activity, early postpartum moderate to vigorous physical activity was either protective or had no effect on other parameters of pelvic floor health. Few women performed substantial vigorous activity, and thus, these results do not apply to women performing strenuous exercise shortly after delivery.

Abstract
OBJECTIVE To determine whether 2 aspects of trunk recovery after childbirth, intraabdominal pressure (IAP) generation and trunk flexor endurance (TFE), predict measures of pelvic floor health 1 year postpartum. METHODS In this prospective cohort study, we enrolled nulliparas in their third trimester and followed up those delivered vaginally for 1 year. We measured IAP while lifting a weighted car seat (IAPLIFT), IAP during TFE testing (IAPTFE), and TFE duration 5 to 10 weeks postpartum and assessed pelvic floor support and symptoms 1 year postpartum. RESULTS Mean age of the 624 participants was 28.7 years. At 5 to 10 weeks postpartum, mean (SD) maximal IAPLIFT and IAPTFE were 47.67 (11.13) and 51.57 (12.34) cm H2O, respectively. Median TFE duration was 126 seconds (Interquartile range, 74-211). At 1 year postpartum, 9.3% demonstrated worse support (maximal vaginal descent at or below hymen) and 54% met criteria for symptom burden (bothersome symptoms in ≥2 domains of Epidemiology of Prolapse and Incontinence Questionnaire). In multivariable models, neither IAPLIFT nor IAPTFE were associated with worse support or symptom burden (P = 0.54-1.00). Trunk flexor endurance duration increased prevalence of worse support (prevalence ratio, 1.05; 95% confidence interval, 1.01-1.08) per 60-second increase, P = 0.005) but not symptom burden (prevalence ratio, 1.00; 95% confidence interval, 0.98-1.03; P = 0.92). CONCLUSIONS These results provide some reassurance to early postpartum women, who are unlikely to perform routine activities that generate IAP far outside the range tested. Further research is needed to understand why women with long TFE durations have increased prevalence of worse support.

Abstract
BACKGROUND Pelvic floor dysfunction (PFD) most commonly results from weakened or injured muscles and ligaments whose purpose is to support the pelvic floor. Many studies have placed vaginal delivery and prolonged second stage of labor (SSL) as major risk factors for PFD, supposedly through generating enhanced pressure in the pelvic area. Although many studies describe the effects of vaginal delivery and labor on structure and function of the pelvic floor, not much is known regarding PFD deriving from pregnancy and its prevalence and severity in the postpartum. We aimed to evaluate whether a correlation exists between PFD symptoms during pregnancy and the duration of the SSL. METHODS We conducted a cross sectional study of 200 women who gave birth at Soroka University Medical Center, Beer-Sheva, Israel. Those who had consented completed the Pelvic Floor Distress Inventory-20 (PFDI-20), a condition specific questionnaire developed to measure quality-of-life and the extent of injury to the pelvic floor in women with all forms of PFD. The duration of the SSL and clinical and obstetrical characteristics were retrieved from the participants' medical records. We assessed correlations using Spearman's correlation coefficient. RESULTS PFD during pregnancy was found to be correlated to the duration of the SSL (R = -0.183, p = .021). When evaluating each component of the PFDI-20 separately, CRAD was significantly correlated with the duration of the SSL (R = -0.195, p = .014). CONCLUSIONS There is a correlation between PFD symptoms during pregnancy, specifically symptoms of CRAD and the duration of the SSL.

Abstract
OBJECTIVES Current validated instruments to screen for pelvic organ prolapse and its sequelae address bulge symptoms, bowel and bladder changes, and sexual intimacy. However, sensitivity is lower in younger women, and there is no instrument specifically designed to screen in postpartum, primiparous women for early changes, that is, changes that may be noticed before the symptom of a bulge or signs of pelvic organ prolapse occur. Our goal was to elucidate early sensations of pelvic floor support changes in primiparous women after their first vaginal delivery. These could be the focus of future studies differentiating such sensations from a normal postpartum, aiding identification of women for further follow-up. METHODS Using comparative focused ethnographic methods, we purposefully sampled and interviewed 17 multiparous women diagnosed with pelvic organ prolapse and 60 primiparous women, half Euro-American and half Mexican American, English or Spanish speaking. Audiotapes were transcribed and then translated. Using inductive coding and matrix analysis, we used constant comparison across transcript data and clustered coded data into body systems-level matrices to arrive at categories of early changes. RESULTS We identified early changes by ethnic group in pelvic area sensations and bowel, bladder, and sexual function, including sensations not mentioned in extant questionnaires. CONCLUSIONS Early changes may be distressing but difficult for women to introduce in a clinical conversation. Querying these changes may enhance patient-provider communication. Future research is needed to validate these items in questionnaires designed to identify women with persistent early changes that may lead to subsequent objective pelvic organ prolapse.

Abstract
OBJECTIVE This study aimed to determine whether measures of muscular fitness modify the effect of intra-abdominal pressure (IAP) during lifting on pelvic floor support. METHODS Participants, primiparous women 1 year after vaginal delivery, underwent the Pelvic Organ Prolapse Quantification examination, measurement of IAP via a vaginal sensor while lifting a weighted car seat, pelvic floor muscle force assessment using an instrumented speculum, grip strength using a hand dynamometer, and trunk flexor endurance by holding an isometric contraction while maintaining a 60-degree angle to the table. We dichotomized pelvic floor support as worse (greatest descent of the anterior, posterior, or apical vagina during maximal strain at or below the hymen) versus better (all points above the hymen). RESULTS Of 825 participants eligible after delivery, 593 (71.9%) completed a 1-year study visit. Mean (SD) age was 29.6 (5.0) years. One year postpartum, 55 (9.3%) demonstrated worse support. There were no differences in IAP during lifting or in other measures of pelvic floor loading between women with better and worse support. In multivariable analyses, neither grip strength nor pelvic floor muscle force modified the effect of IAP on support. In women with trunk flexor endurance duration ≥13 minutes, the odds of worse support increased significantly as IAP increased. No fitness measure modified the effect of other measures of pelvic floor loading on support. CONCLUSIONS Primiparous women with higher IAP during lifting and greater muscular fitness did not have reduced odds of worse pelvic floor support compared with those with lower IAP at the same muscular fitness.

Abstract
OBJECTIVE To understand health-related issues in women following mesh-augmented prolapse surgery. DESIGN Inductive thematic analysis of free-text comments from participants in a cross-sectional study of laparoscopic mesh sacrohysteropexy. SETTING Tertiary urogynaecology centres, United Kingdom. POPULATION Women who underwent laparoscopic mesh sacrohysteropexy by surgeons based at two tertiary urogynaecology centres between 2010 and 2018. METHODS A total of 1766 potential participants were contacted by post and invited to complete paper, online or telephone questionnaires containing a free-text comments section. Of 1121 participants (response proportion 63.5%), 752 (67.1%) provided such comments. These were analysed with a six-stage inductive thematic analysis, using NVivo 11® software. MAIN OUTCOME MEASURES Themes developed from free-text comments. RESULTS Following familiarisation, 29 codes and 189 sub-codes were identified. These defined six themes: pelvic floor symptoms, health status, treatment success, mesh, pain and care received. The majority of comments centred on the first of these six themes. There were concerns about mesh use and a desire for more information. A range of pain symptoms were mentioned, often associated with pelvic floor symptoms, prolapse surgery or mesh. CONCLUSIONS Despite the mesh controversy, pelvic floor symptoms and their impact on quality of life remain the principle concern of women following mesh-augmented prolapse surgery. There is a need for quality, accessible and evidence-based information sources for those women with concerns, and for those considering such surgery in the future, particularly regarding mesh safety and postoperative recovery. The relationships between pain, prolapse, mesh and pelvic floor surgery require further study. TWEETABLE ABSTRACT Following mesh-augmented prolapse surgery, pelvic floor symptoms remain women's main focus; pain deserves further research.

Abstract
OBJECTIVE The aim of the study was to determine whether measures of muscular strength and fitness are associated with pelvic floor muscle (PFM) force 1-year postpartum in a population of primiparous women who delivered vaginally. METHODS This cross-sectional analysis is an ancillary study to an ongoing prospective cohort study and includes 203 primiparous women. Procedures collected 1-year postpartum included maximal PFM force, grip strength, trunk flexor muscle endurance, percent body fat, intra-abdominal pressure during trunk flexor endurance testing, intra-abdominal pressure during strain, and self-reported physical activity. RESULTS The mean (SD) age was 29.8 (5.0) years and the mean (SD) body mass index was 24.5 (5.2) kg/m. Nineteen percent were of Hispanic ethnicity. The median (interquartile range) PFM force was 5.05 (2.86-7.94) N. The median (interquartile range) trunk flexor endurance time was 146.0 (78.0-267.0), whereas the mean (SD) grip strength and percent fat were 32.4 (6.4) kg and 29.4% (10.0), respectively.There were no statistically significant associations between PFM force and any of the measures tested on analyses unadjusted or adjusted for self-report of doing PFM exercises. Of other factors evaluated, non-Hispanic ethnicity, increasing age, self-reported family history of pelvic organ prolapse or urinary incontinence, and normal and obese body mass index (both compared with overweight) were associated with lower PFM force. CONCLUSIONS In primiparous women 1-year postpartum, we found no associations between PFM force and measures of strength and fitness. This study's results are consistent with existing literature that specific, targeted, and consistent pelvic floor exercises are the best way to improve PFM strength.

Pelvic floor muscle training for preventing and treating urinary and faecal incontinence in antenatal and postnatal women. Cochrane Database Syst Rev 2020; 5:CD007471.

Abstract
BACKGROUND About one-third of women have urinary incontinence (UI) and up to one-tenth have faecal incontinence (FI) after childbirth. Pelvic floor muscle training (PFMT) is commonly recommended during pregnancy and after birth for both preventing and treating incontinence. This is an update of a Cochrane Review previously published in 2017. OBJECTIVES To assess the effects of PFMT for preventing or treating urinary and faecal incontinence in pregnant or postnatal women, and summarise the principal findings of relevant economic evaluations. SEARCH METHODS We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, CINAHL, ClinicalTrials.gov, WHO ICTRP, and handsearched journals and conference proceedings (searched 7 August 2019), and the reference lists of retrieved studies. SELECTION CRITERIA We included randomised or quasi-randomised trials in which one arm included PFMT. Another arm was no PFMT, usual antenatal or postnatal care, another control condition, or an alternative PFMT intervention. Populations included women who, at randomisation, were continent (PFMT for prevention) or incontinent (PFMT for treatment), and a mixed population of women who were one or the other (PFMT for prevention or treatment). DATA COLLECTION AND ANALYSIS We independently assessed trials for inclusion and risk of bias. We extracted data and assessed the quality of evidence using GRADE. MAIN RESULTS We included 46 trials involving 10,832 women from 21 countries. Overall, trials were small to moderately-sized. The PFMT programmes and control conditions varied considerably and were often poorly described. Many trials were at moderate to high risk of bias. Two participants in a study of 43 pregnant women performing PFMT for prevention of incontinence withdrew due to pelvic floor pain. No other trials reported any adverse effects of PFMT. Prevention of UI: compared with usual care, continent pregnant women performing antenatal PFMT probably have a lower risk of reporting UI in late pregnancy (62% less; risk ratio (RR) 0.38, 95% confidence interval (CI) 0.20 to 0.72; 6 trials, 624 women; moderate-quality evidence). Antenatal PFMT slightly decreased the risk of UI in the mid-postnatal period (more than three to six months' postpartum) (29% less; RR 0.71, 95% CI 0.54 to 0.95; 5 trials, 673 women; high-quality evidence). There was insufficient information available for the late postnatal period (more than six to 12 months) to determine effects at this time point (RR 1.20, 95% CI 0.65 to 2.21; 1 trial, 44 women; low-quality evidence). Treatment of UI: compared with usual care, there is no evidence that antenatal PFMT in incontinent women decreases incontinence in late pregnancy (very low-quality evidence), or in the mid-(RR 0.94, 95% CI 0.70 to 1.24; 1 trial, 187 women; low-quality evidence), or late postnatal periods (very low-quality evidence). Similarly, in postnatal women with persistent UI, there is no evidence that PFMT results in a difference in UI at more than six to 12 months postpartum (RR 0.55, 95% CI 0.29 to 1.07; 3 trials; 696 women; low-quality evidence). Mixed prevention and treatment approach to UI: antenatal PFMT in women with or without UI probably decreases UI risk in late pregnancy (22% less; RR 0.78, 95% CI 0.64 to 0.94; 11 trials, 3307 women; moderate-quality evidence), and may reduce the risk slightly in the mid-postnatal period (RR 0.73, 95% CI 0.55 to 0.97; 5 trials, 1921 women; low-quality evidence). There was no evidence that antenatal PFMT reduces the risk of UI at late postpartum (RR 0.85, 95% CI 0.63 to 1.14; 2 trials, 244 women; moderate-quality evidence). For PFMT started after delivery, there was uncertainty about the effect on UI risk in the late postnatal period (RR 0.88, 95% CI 0.71 to 1.09; 3 trials, 826 women; moderate-quality evidence). Faecal incontinence: eight trials reported FI outcomes. In postnatal women with persistent FI, it was uncertain whether PFMT reduced incontinence in the late postnatal period compared to usual care (very low-quality evidence). In women with or without FI, there was no evidence that antenatal PFMT led to a difference in the prevalence of FI in late pregnancy (RR 0.64, 95% CI 0.36 to 1.14; 3 trials, 910 women; moderate-quality evidence). Similarly, for postnatal PFMT in a mixed population, there was no evidence that PFMT reduces the risk of FI in the late postnatal period (RR 0.73, 95% CI 0.13 to 4.21; 1 trial, 107 women, low-quality evidence). There was little evidence about effects on UI or FI beyond 12 months' postpartum. There were few incontinence-specific quality of life data and little consensus on how to measure it. AUTHORS' CONCLUSIONS This review provides evidence that early, structured PFMT in early pregnancy for continent women may prevent the onset of UI in late pregnancy and postpartum. Population approaches (recruiting antenatal women regardless of continence status) may have a smaller effect on UI, although the reasons for this are unclear. A population-based approach for delivering postnatal PFMT is not likely to reduce UI. Uncertainty surrounds the effects of PFMT as a treatment for UI in antenatal and postnatal women, which contrasts with the more established effectiveness in mid-life women. It is possible that the effects of PFMT might be greater with targeted rather than mixed prevention and treatment approaches, and in certain groups of women. Hypothetically, for instance, women with a high body mass index (BMI) are at risk of UI. Such uncertainties require further testing and data on duration of effect are also needed. The physiological and behavioural aspects of exercise programmes must be described for both PFMT and control groups, and how much PFMT women in both groups do, to increase understanding of what works and for whom. Few data exist on FI and it is important that this is included in any future trials. It is essential that future trials use valid measures of incontinence-specific quality of life for both urinary and faecal incontinence. In addition to further clinical studies, economic evaluations assessing the cost-effectiveness of different management strategies for FI and UI are needed.

Abstract
The PRECISE Network is a cohort study established to investigate hypertension, fetal growth restriction and stillbirth (described as "placental disorders") in Kenya, Mozambique and The Gambia. Several pregnancy or birth cohorts have been set up in low- and middle-income countries, focussed on maternal and child health. Qualitative research methods are sometimes used alongside quantitative data collection from these cohorts. Researchers affiliated with PRECISE are also planning to use qualitative methods, from the perspective of multiple subject areas. This paper provides an overview of the different ways in which qualitative research methods can contribute to achieving PRECISE's objectives, and discusses the combination of qualitative methods with quantitative cohort studies more generally.We present planned qualitative work in six subject areas (health systems, health geography, mental health, community engagement, the implementation of the TraCer tool, and respectful maternity care). Based on these plans, with reference to other cohort studies on maternal and child health, and in the context of the methodological literature on mixed methods approaches, we find that qualitative work may have several different functions in relation to cohort studies, including informing the quantitative data collection or interpretation. Researchers may also conduct qualitative work in pursuit of a complementary research agenda. The degree to which integration between qualitative and quantitative methods will be sought and achieved within PRECISE remains to be seen. Overall, we conclude that the synergies resulting from the combination of cohort studies with qualitative research are an asset to the field of maternal and child health.

Abstract
Vaginal delivery with obstetrical trauma is a risk factor for pelvic organ prolapse later in life. Loss of fibulin-5 (FBLN5), an elastogenesis-promoting cellular matrix protein, results in prolapse in mice. Here, we evaluated effects of pregnancy, parturition, and obstetrical injury on FBLN5 content, elastic fibers, biomechanics, and histomorphology of the vaginal wall in rats. Further, we analyzed the effects of actinonin, a protease inhibitor, on obstetrical injury of the vaginal wall. Vaginal FBLN5 decreased significantly in pregnancy, and injury resulted in further downregulation. Stiffness of the vaginal wall decreased 82% in pregnant rats and 74% (p = 0.019) with injury relative to uninjured vaginal delivery controls at 3d. Actinonin ameliorated loss of FBLN5, rescued injury-induced loss of elastic fibers and biomechanical properties after parturition, and reduced the area of injury 10-fold. We conclude that pregnancy and parturition have a profound impact on vaginal FBLN5 and biomechanics of the vaginal wall. Further, obstetrical injury has significant deleterious impact on recovery of the vaginal wall from pregnancy. Actinonin, a non-specific matrix metalloprotease inhibitor, improved recovery of the parturient vaginal wall after obstetrical injury.

Abstract
Objective: Most studies about truncal pain during and after pregnancy focus on low back
pain, few prospectively define change in pain, and even fewer evaluate pain
in all three major truncal areas: upper back, lower back, and pelvic girdle.
Thus, the objective of this prospective cohort study was to describe, in
primiparous women delivered vaginally, prevalence rates and severities of
upper back, lower back, and pelvic girdle pain during pregnancy and
6–10 weeks postpartum and to describe the trajectory of pain constellations
between time points. Study design: Participants completed questionnaires at each time point. Pain intensity was
rated on a visual analogue scale ranging from 0 to 100. Results: Of the 288 participants, 94% reported truncal pain during pregnancy, while
75% did so postpartum. Prevalence rates of upper back, lower back, and
pelvic girdle pain with or without other types of pain during pregnancy were
42%, 77%, and 74% and postpartum were 43%, 52%, and 41%, respectively. Pain
severity was highest for women endorsing pain in three locations (median
55–60). Of women with the most common pain constellation during pregnancy,
lower back and pelvic girdle (32%), 18% had persistent low back and pelvic
girdle pain postpartum, 20% had no pain, and the remainder had pain in a
different location. Of women with pain in all three locations during
pregnancy (27%), 34% had persistent pain in three locations postpartum, 13%
had no pain, and the remainder had pain in at least one location. Conclusion: More women experience pain in a constellation of locations than in a single
location. Severity increases as number of pain sites increase. Women with
pain in three sites during pregnancy are least likely to have pain resolve.
Interventions should focus on the entire trunk and not simply one site of
pain.

Abstract
Background During pregnancy, appropriate physical activity plays critical roles in maternal and fetal health. This study investigated the effects of Sophrology childbirth-Kegel-Lamaze respiratory training (SLK triple therapy) on maternal and newborn health, pelvic floor function, and quality of life. Material/Methods Single-pregnant primiparous women involved in this study were divided into the control group (n=120) and the SLK triple therapy group (n=120). SLK triple therapy was taught to and practiced by the women in the SLK triple therapy group. Data on delivery mode (natural delivery or cesarean section), postpartum complications (postpartum urinary incontinence, postpartum hemorrhage), and birth process were recorded. Apgar scores and body weight of newborns were evaluated. Pelvic floor function, postpartum emotion, and sexual functions were assessed. Results Women in the SLK triple therapy group had significantly better natural delivery rate compared to the control group (p<0.05). SLK triple therapy significantly decreased the postpartum urinary incontinence rate and reduced the postpartum hemorrhage rate compared to the control group (p<0.05). Birth process and postpartum hemorrhage volume in the SLK triple therapy group were also significantly lower compared to the control group (p<0.05). Apgar scores were significantly lower and body weights were significantly higher in the SLK triple therapy group compared to the control group (p<0.05). SLK triple therapy significantly improved pelvic floor function compared to the control group (p<0.05). SLK triple therapy significantly decreased SDS scores and enhanced FSFI scores compared to the control group (p<0.05). Conclusions SLK triple therapy improved maternal and fetal health by improving pregnancy outcomes, promoting postpartum pelvic floor function, reducing the incidence of depression, and enhancing sexual function. Therefore, SLK triple therapy has great utility in treating primiparous women.

Abstract
Pelvic floor disorders are caused by weakening or damage to the tissues lining the bottom of the abdominal cavity. These disorders affect nearly 1 in every 4 women in the United States and symptoms that drastically diminish a patient’s quality of life. Vaginal closure force is a good measure of pelvic health, but current vaginal dynamometers were not designed for the rigors of hospital reprocessing, often failing due to sensor degradation through repeated sterilization processes. In order to obtain measurements of vaginal closure force in a large study, we designed a vaginal dynamometer that utilizes a removable intra-abdominal sensor already in production for the study. The sensor’s existing data acquisition system was modified to transmit to a tablet allowing the user to view data in real-time. The new speculum design allowed a single sensor to measure vaginal closure force before being used to collect intra-abdominal pressure data in the same study visit. The measurements taken with the new speculum were similar to measurements taken with a previously reported vaginal dynamometer.

Abstract
OBJECTIVE To describe sleep quality and sleep duration in primiparous women 6 months postpartum and to determine whether sleep quality is associated with 24-hour physical activity assessed using triaxial wrist accelerometry and a novel analytic technique, functional data analysis (FDA). METHODS Six months postpartum, participants wore a triaxial wrist accelerometer for 7 days and completed the Pittsburgh Sleep Quality Index (PSQI). We categorized sleep quality as good (score ≤5) or poor (>5). Data were summarized as vector magnitude of accelerations net of local gravity, or "Euclidean Norm Minus One" (ENMO, mg), in 5-second epochs. Using FDA, we modeled ENMO as a continuously changing, functional outcome predicted by sleep quality. We also compared mean total ENMO per 24-hour day, mean minutes of moderate to vigorous physical activity (MVPA) and of light activity/day, and mean minutes of MVPA in 10-minute bouts/day by sleep quality. RESULTS Of 365 women that completed the PSQI, 215 (59%) reported poor sleep quality. Two hundred ninety-six women completed both the PSQI and valid accelerometry. With the exception of one brief period around noon, sleep quality was not significantly associated with 24-hour physical activity according to FDA. Women with poor sleep quality had slightly greater total mean activity, minutes of light activity, and minutes of MVPA per day, but no difference in minutes of MVPA in at least 10-minute bouts. CONCLUSION Poor sleep quality is common 6 months postpartum. We identified no clinically significant differences in physical activity metrics between women with good and poor quality sleep.

Abstract
OBJECTIVES Intra-abdominal pressure (IAP) may contribute to pelvic floor health, although the direction and magnitude of such an effect, if any, are not yet known. Identifying individual characteristics, and in particular modifiable factors, associated with higher IAP during recovery from vaginal childbirth might serve to mitigate early pelvic floor dysfunction. The aim of this study was to identify characteristics associated with maximal IAP during lifting in postpartum primiparous women who delivered vaginally. METHODS At 6 to 10 weeks postpartum, we measured maximal IAP, assessed via an upper vaginal sensor, as participants (enrolled in an ongoing cohort study) lifted a weighted car seat (12.5 kg). We evaluated whether the following independent variables were associated with maximal IAP: age, ethnicity, body mass index, height, abdominal circumference, weight gain during pregnancy, lifting time, breath holding during lifting, lifting technique, measures of muscular fitness, and days since delivery. RESULTS In the 206 participants, weight, waist circumference, body mass index, and days since delivery were positively associated with mean maximal IAP during lifting, whereas IAP decreased as height increased. As the duration of the lifting task increased, mean maximal IAP during lifting also increased, but there were no associations between lifting technique or breath holding during lifting and IAP. Neither pelvic floor muscle strength nor abdominal muscle endurance was associated with IAP during lifting. CONCLUSIONS Other than measures of body habitus and lifting duration, we did not identify modifiable factors that could mitigate maximal pressures experienced by the pelvic floor during the early postpartum period.

Compliance with wrist-worn accelerometers in primiparous early postpartum women. Heliyon 2019; 5:e01193. [PMID: 30775582 PMCID: PMC6360339 DOI: 10.1016/j.heliyon.2019.e01193] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Revised: 11/28/2018] [Accepted: 01/28/2019] [Indexed: 11/21/2022] Open
Abstract
Background There are few studies that objectively assess physical activity using accelerometry in postpartum women and none that do so before 3 months postpartum. It is not known whether accelerometry can be successfully used in the early postpartum period and thus benefit studies designed to assess the health benefits and risks of early physical activity. Wear compliance may be substantially lower several weeks after childbirth, given the overwhelming nature of the early postpartum period, particularly for first time mothers. The aims of this study were to 1) describe the methods used to facilitate protocol compliance of wrist-worn accelerometry, 2) describe device usage and wear time in early postpartum primiparous women and 3) to place the compliance characteristics of early postpartum primiparous women in our study in context with that of other studies of postpartum women and standards published by large, physical activity surveillance studies. Methods Participants were primiparous women who were enrolled at 3rd trimester in a larger ongoing prospective cohort study, delivered vaginally, and lived in a 60 mile radius of the research site. The parent study was designed to evaluate the effects of early physical activity on pelvic floor health. Participants wore a wrist accelerometer (ActiGraph™ GT3XLink device) over two 7-day periods, 2-3 weeks and 5-6 weeks postpartum. We developed a protocol based on best practices to enhance compliance in this population. The Choi (2011) algorithm was used to determine wear time. Results Of all participants, 82.6% (166 of 201 eligible) and 70.1% (141 of 201 eligible) at 2-3 and 5-6 weeks, respectively, received and wore a functional device in the correct study time-frame for at least 7 days. Of participants that received a functional device, 94.3% (166/176) and 86.5% (141/163) wore the device for at least 7 days, with mean wear times of 1348.0 (135.8) minutes/day and 1313.5 (152) minutes/day, respectively. At 2-3 weeks, 96.1% and 90.4% met the NHANES and Whitehall II Study wear standards, respectively, while at 5-6 weeks, 93.9% and 84.1% did so. Conclusion Despite challenges in conducting physical activity research in postpartum women, adherence to wrist-worn accelerometry is high with this protocol.

Abstract
BACKGROUND About one-third of women have urinary incontinence and up to one-tenth have faecal incontinence after childbirth. Pelvic floor muscle training (PFMT) is commonly recommended during pregnancy and after birth for both prevention and treatment of incontinence.This is an update of a review previously published in 2012. OBJECTIVES To determine the effectiveness of pelvic floor muscle training (PFMT) in the prevention or treatment of urinary and faecal incontinence in pregnant or postnatal women. SEARCH METHODS We searched the Cochrane Incontinence Specialised Register (16 February 2017) and reference lists of retrieved studies. SELECTION CRITERIA Randomised or quasi-randomised trials in pregnant or postnatal women. One arm of the trial included PFMT. Another arm was no PFMT, usual antenatal or postnatal care, another control condition, or an alternative PFMT intervention. DATA COLLECTION AND ANALYSIS Review authors independently assessed trials for inclusion and risk of bias. We extracted data and checked them for accuracy. Populations included: women who were continent (PFMT for prevention), women who were incontinent (PFMT for treatment) at randomisation and a mixed population of women who were one or the other (PFMT for prevention or treatment). We assessed quality of evidence using the GRADE approach. MAIN RESULTS The review included 38 trials (17 of which were new for this update) involving 9892 women from 20 countries. Overall, trials were small to moderate sized, and the PFMT programmes and control conditions varied considerably and were often poorly described. Many trials were at moderate to high risk of bias. Other than two reports of pelvic floor pain, trials reported no harmful effects of PFMT.Prevention of urinary incontinence: compared with usual care, continent pregnant women performing antenatal PFMT may have had a lower risk of reporting urinary incontinence in late pregnancy (62% less; risk ratio (RR) for incontinence 0.38, 95% confidence interval (CI) 0.20 to 0.72; 6 trials, 624 women; low-quality evidence). Similarly, antenatal PFMT decreased the risk of urinary incontinence in the mid-postnatal period (more than three to six months' postpartum) (29% less; RR 0.71, 95% CI 0.54 to 0.95; 5 trials, 673 women; moderate-quality evidence). There was insufficient information available for the late (more than six to 12 months') postnatal period to determine effects at this time point.Treatment of urinary incontinence: it is uncertain whether antenatal PFMT in incontinent women decreases incontinence in late pregnancy compared to usual care (RR 0.70, 95% CI 0.44 to 1.13; 3 trials, 345 women; very low-quality evidence). This uncertainty extends into the mid- (RR 0.94, 95% CI 0.70 to 1.24; 1 trial, 187 women; very low-quality evidence) and late (RR 0.50, 95% CI 0.13 to 1.93; 2 trials, 869 women; very low-quality evidence) postnatal periods. In postnatal women with persistent urinary incontinence, it was unclear whether PFMT reduced urinary incontinence at more than six to 12 months' postpartum (RR 0.55, 95% CI 0.29 to 1.07; 3 trials; 696 women; very low-quality evidence).Mixed prevention and treatment approach to urinary incontinence: antenatal PFMT in women with or without urinary incontinence (mixed population) may decrease urinary incontinence risk in late pregnancy (26% less; RR 0.74, 95% CI 0.61 to 0.90; 9 trials, 3164 women; low-quality evidence) and the mid-postnatal period (RR 0.73, 95% CI 0.55 to 0.97; 5 trials, 1921 women; very low-quality evidence). It is uncertain if antenatal PFMT reduces urinary incontinence risk late postpartum (RR 0.85, 95% CI 0.63 to 1.14; 2 trials, 244 women; low-quality evidence). For PFMT begun after delivery, there was considerable uncertainty about the effect on urinary incontinence risk in the late postnatal period (RR 0.88, 95% CI 0.71 to 1.09; 3 trials, 826 women; very low-quality evidence).Faecal incontinence: six trials reported faecal incontinence outcomes. In postnatal women with persistent faecal incontinence, it was uncertain whether PFMT reduced incontinence in the late postnatal period compared to usual care (RR 0.68, 95% CI 0.24 to 1.94; 2 trials; 620 women; very low-quality evidence). In women with or without faecal incontinence (mixed population), antenatal PFMT led to little or no difference in the prevalence of faecal incontinence in late pregnancy (RR 0.61, 95% CI 0.30 to 1.25; 2 trials, 867 women; moderate-quality evidence). For postnatal PFMT in a mixed population, there was considerable uncertainty about the effect on faecal incontinence in the late postnatal period (RR 0.73, 95% CI 0.13 to 4.21; 1 trial, 107 women, very low-quality evidence).There was little evidence about effects on urinary or faecal incontinence beyond 12 months' postpartum. There were few incontinence-specific quality of life data and little consensus on how to measure it. We found no data on health economics outcomes. AUTHORS' CONCLUSIONS Targeting continent antenatal women early in pregnancy and offering a structured PFMT programme may prevent the onset of urinary incontinence in late pregnancy and postpartum. However, the cost-effectiveness of this is unknown. Population approaches (recruiting antenatal women regardless of continence status) may have a smaller effect on urinary incontinence, although the reasons for this are unclear. It is uncertain whether a population-based approach for delivering postnatal PFMT is effective in reducing urinary incontinence. Uncertainty surrounds the effects of PFMT as a treatment for urinary incontinence in antenatal and postnatal women, which contrasts with the more established effectiveness in mid-life women.It is possible that the effects of PFMT might be greater with targeted rather than mixed prevention and treatment approaches and in certain groups of women. Hypothetically, for instance, women with a high body mass index are at risk factor for urinary incontinence. Such uncertainties require further testing and data on duration of effect are also needed. The physiological and behavioural aspects of exercise programmes must be described for both PFMT and control groups and how much PFMT women in both groups do, to increase understanding of what works and for whom.Few data exist on faecal incontinence or costs and it is important that both are included in any future trials. It is essential that future trials use valid measures of incontinence-specific quality of life for both urinary and faecal incontinence.

Abstract
Many undergraduate students in kinesiology are interested in clinical careers and seek research opportunities for advanced study and unique learning experiences. This paper describes a process of engaging undergraduate students in a multi-disciplinary, NIH-funded Program Project investigating factors that may affect pelvic floor support and symptoms in primiparous women during the first year postpartum. Students complete general and protocol-specific training prior to engagement, have specific tasks that reinforce skill development and require independence, and are invited to participate in additional opportunities with the investigative team. The topic of pelvic floor health is novel to most students and participation in this research expands their knowledge beyond a mainstream kinesiology curriculum. Institutionalizing this type of program could formalize undergraduate student research experiences and facilitate ongoing clinical research efforts with a kinesiology focus.

Abstract
Intra-abdominal pressure may be one of the few modifiable risk factors associated with developing a pelvic floor disorder. With one in eight women having surgery to correct a pelvic floor disorder in their lifetimes, intra-abdominal pressure may be a key to understanding the disease etiology and how to mitigate its occurrence and progression. Many traditional methods of intra-abdominal pressure measurement have limitations in data quality, environment of use, and patient comfort. We have modified a previously reported intravaginal pressure transducer that has been shown to overcome other intra-abdominal pressure measurement technique limitations (Coleman et al. 2012). Our modifications to the intravaginal pressure transducer make it easier to use, less costly, and more reliable than previous designs, while maintaining accuracy, integrity, and quality of data. This device has been used in over 400 participants to date as part of one of the most comprehensive studies examining the relationship between intra-abdominal pressure and pelvic floor disorders.
