Pelvic floor disorder prevalence and risk factors in a cohort of parous Ugandan women.

OBJECTIVES: The aim of this study was to determine the prevalence of pelvic floor disorders (PFDs) and associated risk factors among parous Ugandan women. METHODS: We performed a cross-sectional study of parous Ugandan women. Demographics and assessment for PFD were obtained. The presence of PFD was defined by participant symptom report, standardized questionnaires, and standard physical examination (pelvic organ prolapse quantification [POP-Q] and cough stress test [CST]). RESULTS: A total of 159 women were enrolled in the study between June 2022 and June 2023. The median age was 35 years and median parity was 4. Forty-four (28%) women in the cohort reported symptoms of urinary incontinence. No women reported symptoms of pelvic organ prolapse or anal incontinence. Seventy-two (46%) participants had a positive CST and 93 (58.3%) had stage II or greater prolapse based on the POP-Q. Cesarean section was found to have a protective effect for the development of PFD (odds ratio [OR] 0.22, 95% confidence interval [CI] 0.07-0.59, P = 0.004). CONCLUSION: PFDs are prevalent among parous Ugandan women at rates similar to cohorts in other low- and middle-income countries. Cesarean section seems to be a protective factor against developing PFDs.

Association Between Physical Activity and Pelvic Floor Disorders in Parous Ugandan Women.

INTRODUCTION AND HYPOTHESIS: The aim was to assess the association between the degree of physical activity (PA) and the presence of pelvic floor disorders (PFDs) in a cohort of parous Ugandan women. METHODS: In this cross-sectional study, PFDs were measured using symptom assessment, standardized questionnaires (Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire), and a standardized physical examination (POP-Q and cough stress test [CST]). Degree of PA was assessed using the International Physical Activity Questionnaire. Interquartile ranges were used to describe the age, parity, and body mass index (BMI) of participants. To examine the association between PA and PFDs, a log transformation was applied to the weekly minutes of PA variable and a logistic regression model was constructed with weekly minutes of moderate/vigorous PA, age, BMI, and parity as the predictors. RESULTS: A total of 159 women were enrolled. Median age was 35 (IQR 32-37), median parity 4 (IQR 3-5), and median BMI 29.0 (IQR 24-33). The prevalence of PFD as determined by symptom assessment was 28% (n=44). The most frequent stage of prolapse identified by POP-Q was stage II (57%, n=91). Thirty-six percent of the women (n=58) reported vigorous PA. Ninety-nine percent of the cohort (n=158) reported moderate PA. When controlling for age, parity, and BMI there was a significant positive association between PFD (defined as a combination of stage II prolapse, positive CST, and urinary incontinence (UI)) and moderate PA (OR 2.20, 95% CI 1.08-5.14, p value 0.045). CONCLUSIONS: Pelvic floor disorders are common among parous Ugandan women and are associated with moderate PA when controlling for age, BMI, and parity. Understanding the risk factors associated with PFD in this population may better equip providers to screen and care for individuals.

Association of Constipation with Modes of Delivery: A Retrospective Questionnaire-based Study.

INTRODUCTION AND HYPOTHESIS: Pelvic floor damage can contribute to pelvic floor dysfunction, including constipation. Most studies focus on constipation during pregnancy, whereas information regarding the mode of delivery in relation to constipation is limited. We hypothesise that women with a history of vaginal delivery report constipation more often than women with a history of caesarean section. METHODS: This was a retrospective cross-sectional multicentre study conducted in the Netherlands. All included patients (n = 2,643) completed the Groningen Defecation and Fecal Continence questionnaire to assess bowel problems of the last 6 months. Parametric tests, Chi-squared, univariable and multivariable regression analyses were performed. RESULTS: Among 2,643 parous women, 2,248 delivered vaginally (85.1%) and 395 (14.9%) by caesarean section. Altogether, 649 women (24.6%) suffered from constipation. Women in the vaginal delivery group were constipated more often than women in the caesarean section group (25.5% versus 19.0%, p = 0.005). For women who had delivered vaginally, multivariable regression analysis showed an odds ratio for constipation of 1.47 (95% confidence interval, 1.109-1.938, p = 0.007). The odds ratio for constipation in women with a spontaneous perineal tear was 1.4 times higher than in women with an intact perineum (p = 0.030). Furthermore, the vaginal delivery group reported difficulties regarding bowel emptying (p = 0.048), straining (p = 0.027), incomplete defecation (p = 0.043), not able to defecate daily (p = 0.018), manually assisted defecation (p = 0.015) and had higher Renzi scores (p = 0.043) more often. CONCLUSIONS: Women in the vaginal delivery group have higher prevalences and odds ratios for constipation. Furthermore, a perineal tear during vaginal delivery increases the odds ratio for constipation.

Parous women perform less moderate to vigorous physical activity than their nulliparous peers: a population-based study in Denmark.

OBJECTIVES: The World Health Organization (WHO) highlights parous women as a key population for monitoring trends of physical activity (PA). We aimed to estimate the proportion of Danish women non-adhering to WHO PA guidelines in parous women compared with nulliparous women and to describe leisure-time PA intensity in each of these groups. STUDY DESIGN: Cross-sectional study. METHODS: This population-based study builds on a sample of 27,668 women aged 16-40 years from the Danish National Health Survey 2021. These data were linked with childbirth data from the Danish National Birth Registry. The primary outcome was self-reported weekly hours of moderate to vigorous leisure-time PA (MVPA) dichotomized into: (i) adhering to WHO guidelines for MVPA or (ii) not adhering to WHO guidelines for MVPA. Binomial regression analysis was used to calculate prevalence proportions (PP) and prevalence proportion ratios (PPR). RESULTS: Of the 27,668 women, a total of 20,022 were included; 9338 (46.6%) parous women and 10,684 (53.4%) nulliparous women. The PP of women non-adhering to WHO PA guidelines was 63.8% (95% CI 62.9-64.8) for parous and 51.3% (95% CI 50.4-52.3) for nulliparous women, corresponding to a PPR of 1.24 (95% CI 1.21; 1.27). CONCLUSIONS: The proportion of parous women who did not adhere to WHO PA guidelines for MVPA was 24% higher than that of nulliparous women. This highlights parous women as a subgroup of the adult population at increased risk of non-adherence to WHO PA guidelines. These findings call for future research to inform new strategies aiming to promote PA in parous women.

The association between the interdelivery interval and early postpartum urinary incontinence in women who had consecutive vaginal deliveries: a retrospective cohort study.

Background: Urinary incontinence (UI) is associated with obstetric-related factors; however, the association between the timing of deliveries and UI remains unclear. We examined the association between the interdelivery interval (IDI) and early postpartum UI. Methods: This retrospective cohort study included 2,492 parous women who had consecutive singleton, full-term, and vaginal deliveries. UI was self-reported by the participants from 42 to 60 days postpartum and was classified using the International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form. The IDI was measured as the number of months between 2 consecutive live births, and the participants were divided into 4 groups based on the IDI quartiles. The associations between the IDI and early postpartum UI were assessed using multiple logistic regression models. Results: The median [interquartile range] IDI for the entire cohort was 62 [40-90] months at the baseline. In general, the restricted cubic splines showed a U-shaped curve association between the IDI and the incidence of early postpartum UI. After fully adjusting for potential confounders, a longer IDI was associated with a lower adjusted odds ratio (aOR) of postpartum UI. Among the 4 groups, the Quartile 3 IDI group had the lowest aOR [aORQuartile 1-Quartile 2: 0.48 (95% CI: 0.36-0.63); aORQuartile 1-Quartile 3: 0.37 (95% CI: 0.27-0.49); aORQuartile 1-Quartile 4: 0.40 (95% CI: 0.28-0.57); the P value for the trend was <0.001). The association between the IDI and UI was more pronounced in the younger women (<35 years old) and the women with a pre-pregnancy body mass index of <25 kg/m2 (the P values for both interactions were <0.01). Conclusions: We found that the IDI was independently associated with the incidence of early postpartum UI in parous women. IDI ≥41 months was associated with a lower risk of postpartum UI compared to IDI <41 months.

Association between Breastfeeding and Restrictive Spirometric Pattern in Women Aged over 40 Years: A Cross-Sectional Study.

Objectives: Restrictive spirometric pattern (RSP) has a prevalence of 5.4−9.2% and is associated with various respiratory symptoms, comorbidities, and increased mortality. Breastfeeding has important effects on maternal health; however, the effects of breastfeeding on pulmonary function remain unclear. This study aimed to investigate the effects of breastfeeding on maternal pulmonary function, particularly the risk of RSP. Methods: Retrospective, cross-sectional observational study enrolling parous women aged >40 years who participated in the Korea National Health and Nutrition Examination Survey from 2013−2018. RSP was defined using the FEV1/FVC ratio and FVC outcomes of the pulmonary function test. The adjusted odds ratios (OR) for RSP were calculated using multivariate logistic regression. Results: Of 9261 parous women, 913 (9.9%) had RSP. Breastfeeding (≥1 month) was associated with a reduced risk of RSP (OR: 0.75 [0.60−0.92]) when adjusted for age, body mass index, smoking status, other diseases, socioeconomic status, and maternal risk factors. The adjusted ORs for RSP for women decreased further with increasing duration of breastfeeding (p for trend: 0.0004). The FEV1, FVC, and FVC% were higher in women who breastfed than in those who did not breastfeed (by 0.0390 L, 0.0521 L, 0.9540% p, respectively). Conclusions: There is an association between breastfeeding and pulmonary function in parous women. Breastfeeding was associated with a lower prevalence of RSP in parous women aged >40 years old, suggesting that breastfeeding may have a beneficial effect on maternal pulmonary function.

Decreased brain functional connectivity associated with cognitive dysfunction in women with second pregnancy.

Purpose: Previous research has found that women with second pregnancy may have an increased risk of cognitive dysfunction. This study aims to investigate the intrinsic functional connectivity (FC) pattern of the DMN anchored on posterior cingulate cortex (PCC) in postpartum women, especially the parous women using resting-state functional magnetic resonance imaging (rs-fMRI). Methods: Twenty parous women, 26 primiparous women, and 30 nulliparous women were included for rs-fMRI scan. They were age and education well matched. A seed based FC method was conducted to reveal FC patterns with other brain regions using a region of interest in the PCC. The relationships between FC patterns and cognitive performance were further detected. Results: Relative to primiparous women, parous women had significantly decreased FC primarily between the PCC and the right middle frontal gyrus and right parahippocampal gyrus. The decreased FC to the right parahippocampal gyrus in parous women was positively associated with the reduced DST scores (rho = 0.524, p = 0.031). Moreover, parous women compared with nulliparous women showed significantly decreased FC between the PCC and the left superior frontal gyrus and left middle frontal gyrus. The reduced FC to the left superior frontal gyrus in parous women was also positively associated with the lower DST scores (rho = 0.550, p = 0.022). Conclusion: Our result highlights that women with second pregnancy revealed decreased FC between the DMN regions with the parahippocampal gyrus and prefrontal cortex, which was correlated with specific impaired cognitive function. This study may provide new insights into the neuropathological mechanisms of postpartum cognitive impairment and enhance our understanding of the neurobiological aspects during postpartum period.

Acute effect of Sit-up versus Curl-up on the interrecti distance: A cross-sectional study in parous women.

BACKGROUND: A weakened pelvic floor is less efficient counteracting the increased intra-abdominal pressure during exercise. While intra-abdominal pressure is higher in Sit-up than in Curl-up, Sit-up continues to be practiced in fitness classes. This raises the question of whether it has advantages over the Curl-up for instance in reducing the interrecti distance (IRD), a goal searched by many parous women. IRD has been shown to be acutely reduced during Curl-up. OBJECTIVES: To determine if the IRD is more reduced during Sit-up than during Curl-up. METHODS: Parous women with an IRD greater than 15mm were included in the study. IRD was measured at 20mm above umbilicus with a caliper in Head-lift, Curl-up, Sit-up and Drawing-in+Curl-up. IRD was compared across the four conditions using a one-way Anova test with repeated measures and Bonferroni correction between pairwise comparisons. RESULTS: Nineteen parous women aged between 28 and 54 participated in this study. Compared to Head-lift (20.3±3.9mm), the IRD was significantly decreased during the Curl-up (12.2±3.0mm) and the Sit-up (12.1±3.6mm), but not during the Drawing-in+Curl-up (18.4±4.9mm). There was no significant difference in IRD between Curl-up and Sit-up. CONCLUSION: IRD was similarly acutely reduced during Curl-up and Sit-up. The long-term effect of Curl-up on the IRD and on the pelvic floor muscles needs to be studied. IMPACT: To reduce IRD in parous women Curl-up rather than Sit-up should be practiced. Fitness coaches should consider this information especially with classes attended by parous women, many of whom complain about pelvic floor disorders. LEVEL OF EVIDENCE: EL05.

Birthweight difference between deliveries and the risk of obstetric anal sphincter injury in parous women.

INTRODUCTION AND HYPOTHESIS: While obstetric anal sphincter injury (OASI) is less frequent in parous compared to nulliparous women, it remains a major concern affecting quality of life of women worldwide. The aim of this study was to evaluate the association between birthweight (BW) difference between deliveries and risk of OASI in parous women. METHODS: We performed a retrospective case-control study including parous women with at least one previous vaginal delivery who were diagnosed with OASI. The control group consisted of parous women who did not have OASI during vaginal delivery. Controls were matched in a 1:2 ratio by year of birth, maternal age, and parity. Medical history, obstetric background, and current labor-related data were compared. Further univariate and multivariable analyses were performed, assessing for risk factors for OASI. RESULTS: One hundred eight parous women who had a diagnosis of OASI and a control group of 216 parturients who delivered without OASI were included in the final analysis. Differences between the current BW and the preceding and maximal previous BW were evaluated. There were significantly higher rates of women who had a larger neonate with > 500 g difference between the current and previous BW in the OASI group than in those with no OASI (28.7% vs. 12.30%, respectively; p < 0.001). Following a multivariable analysis for the dependent parameter of OASI, the following parameters were found to be independently associated with OASI outcome: previous operative vaginal delivery, BW ≥ 90th percentile, and current BW ≥ 500 g compared to previous maximal BW. CONCLUSIONS: In parous women, neonatal BW increase between deliveries of > 500 g is associated with OASI.

Obstetric anal sphincter injury following previous vaginal delivery.

INTRODUCTION AND HYPOTHESIS: Obstetric anal sphincter injury (OASI) is a debilitating complication of vaginal delivery. The aim of this study was to identify risk factors for OASI in women with a previous vaginal delivery. We further attempted to detect specific risk factors for severe OASI in this subgroup. METHODS: We conducted a retrospective cohort study between 2003 and 2019. The study group included women who had a singleton, live, vertex, vaginal delivery at term and who also had at least one previous vaginal delivery. The control group included women with at least one previous vaginal delivery without OASI. General medical history, obstetric history, and ante-, intra- and post-partum data were collected and compared between groups. RESULTS: Following implementation of the inclusion criteria, 79,176 women were included. Allocation to study groups was according to OASI occurrence: 135 patients (0.2%) had a third- or fourth-degree perineal tear, while 79,041 patients (99.8%) had no such injury. Multivariate analysis revealed that one previous vaginal delivery, birthweight ≥ 3900 g (90th percentile), vacuum-assisted vaginal delivery and episiotomy were associated with increased risk of OASI. Comparison of more severe OASI (3C and 4th-degree) cases to the control group showed similar results with the addition of prolonged second stage and younger age to risk factors associated with severe OASI while episiotomy was no longer significant. CONCLUSION: In women with a previous vaginal delivery, one vs. two or more previous vaginal deliveries, increased birthweight, vacuum-assisted vaginal delivery and episiotomy are risk factors for OASI.

Association between breastfeeding and preeclampsia in parous women: a case -control study.

BACKGROUND: Preeclampsia is a global health problem and it is the main cause of maternal and perinatal morbidity and mortality. Breastfeeding has been reported to be associated with lower postpartum blood pressure in women with gestational hypertension. However, there is no published data on the role that breastfeeding might play in preventing preeclampsia. The aim of the current study was to investigate if breastfeeding was associated with preeclampsia in parous women. METHOD: A case-control study was conducted in Saad Abualila Maternity Hospital in Khartoum, Sudan, from May to December 2019. The cases (n = 116) were parous women with preeclampsia. Two consecutive healthy pregnant women served as controls for each case (n = 232). The sociodemographic, medical, and obstetric histories were gathered using a questionnaire. Breastfeeding practices and duration were assessed. RESULTS: A total of 98 (84.5%) women with preeclampsia and 216 (93.1%) women in the control group had breastfed their previous children. The unadjusted odds ratio (OR) of preeclampsia (no breastfeeding vs breastfeeding) was 3.55, 95% confidence interval (CI) 1.64,7.70 and p value = 0.001 based on these numbers. After adjusting for age, parity, education level, occupation, history of preeclampsia, history of miscarriage, body mass index groups the adjusted OR was 3.19, 95% CI 1.49, 6.82 (p value = 0.006). CONCLUSION: Breastfeeding might reduce the risk for preeclampsia. Further larger studies are required.

Association of breastfeeding and risk of metabolic syndrome and its components in postmenopausal parous women: Korea national health and nutrition examination survey (2010 ~ 2016).

BACKGROUND: Understanding the relationship between breastfeeding (BF) and metabolic syndrome (Mets) is important for maternal long-term health benefits and disease prevention. This study aimed to examine the association between BF and Mets and its components among postmenopausal parous Korean women. METHODS: This cross-sectional study on 10,356 Korean women used nationally representative data from the KNHANES from 2010 to 2016. Anthropometric, laboratory data and manual BP were measured. A multivariate logistic regression analysis was conducted to examine the association of BF with Mets and its components after adjusting for potential confounding variables. A p-value < 0.05 was to be considered statistically significant. RESULTS: Mets was present in 42% of the study participants. The BF group had low household income and education level. The prevalence of Mets in the BF group was higher than that in the non-BF group (42.69% vs. 34.76%, p <  0.001). BF was associated with increased risk of Mets (odds ratio [OR]: 1.4, 95% confidence interval [CI]: 1.18-1.65, p <  0.001). The BF group was at higher risks for diabetes (OR: 1.5, 95%CI: 1.14-1.98), hypertension (OR: 1.32, 95%CI: 1.03-1.68), hypertriglyceridemia (OR: 1.42, 95%CI: 1.02-1.99) and low high-density lipoprotein cholesterol (OR: 1.32, 95%CI: 1.06-1.65). CONCLUSION: In this study, BF did not affect decreasing the prevalence of Mets and its components.

Country of first birth and neonatal outcomes in migrant and Norwegian-born parous women in Norway: a population-based study.

BACKGROUND: This study compares subsequent birth outcomes in migrant women who had already had a child before arriving in Norway with those in migrant women whose first birth occurred in Norway. The aim of this study was to investigate the associations between country of first birth and adverse neonatal outcomes (very preterm birth, moderately preterm birth, post-term birth, small for gestational age, large for gestational age, low Apgar score, stillbirth and neonatal death) in parous migrant and Norwegian-born women. METHODS: National population-based study including second and subsequent singleton births in Norway from 1990 to 2016. Data were retrieved from the Medical Birth Registry of Norway and Statistics Norway. Neonatal outcomes were compared between births to: 1) migrant women with a first birth before immigration to Norway (n = 30,062) versus those with a first birth after immigration (n = 66,006), and 2) Norwegian-born women with a first birth outside Norway (n = 6205) versus those with a first birth in Norway (n = 514,799). Associations were estimated as crude and adjusted odds ratios (aORs) with 95% confidence intervals (CIs) using multiple logistic regression. RESULTS: Migrant women with a first birth before immigrating to Norway had increased odds of adverse outcomes in subsequent births relative to those with a first birth after immigration: very preterm birth (22-31 gestational weeks; aOR = 1.27; CI 1.09-1.48), moderately preterm birth (32-36 gestational weeks; aOR = 1.10; CI 1.02-1.18), post-term birth (≥42 gestational weeks; aOR = 1.19; CI 1.11-1.27), low Apgar score (< 7 at 5 min; aOR = 1.27; CI 1.16-1.39) and stillbirth (aOR = 1.29; CI 1.05-1.58). Similar results were found in the sample of births to Norwegian-born women. CONCLUSIONS: The increased odds of adverse neonatal outcomes for migrant and Norwegian-born women who had their first births outside Norway should serve as a reminder of the importance of taking a careful obstetric history in these parous women to ensure appropriate care for their subsequent pregnancies and births in Norway.

Epidemiology of ovarian cancers in Zaria, Northern Nigeria: a 10-year study.

BACKGROUND: Globally, the absence of a premalignant stage of ovarian cancer and a reliable screening tool make early diagnosis difficult. Locally, poverty, ignorance, and lack of organized cancer services make prognosis poor. We describe the epidemiological features of ovarian cancer seen at Ahmadu Bello University Teaching Hospital Zaria, Northern Nigeria, a tertiary referral center, over a 10-year period in this challenging setting. METHODS: All cases of histologically diagnosed ovarian cancer between January 1, 2004 and December 31, 2013 were included in the study. Case notes were retrieved to collect clinical data including age, parity, clinical stage of disease at presentation, and known associated factors. Results were analyzed using Epi info™. RESULTS: A total of 78 patients were included in the study. About 4-13 cases were seen every year with a tendency to increasing incidence. The patients were aged 8-80 years with mean of 37 years. Sixty-two (79.5%) patients were premenopausal while postmenopausal women accounted for only seven cases or 9.0%. There were 17 cases (22.3%) of aggressive cancers in patients aged ≤20 years. A majority of the patients, 65 (83.3%), were parous with only nine (11.5%) patients being nulliparous. Serous cyst adenocarcinoma accounted for 32 (41%) cases. Granulosa cell tumor was the second commonest with 18 cases (23.1%). The mean age of occurrence of serous cyst adenocarcinoma was 31 years and for epithelial ovarian cancers in general it was 33.5 years. Endometrioid adenocarcinoma was rare with only one case in 10 years. Factors like age, parity, and premenopausal status did not appear to be protective to the occurrence of malignant ovarian tumor in this group. CONCLUSION: Increasing numbers of patients with ovarian cancer were seen over the 10-year period. Young, premenopausal, parous women made up the majority of cases. Serous cystadenocarcinoma was the most common histological variant.

Duration of the active phase of labor in spontaneous and induced labors.

INTRODUCTION: The aim of the study was to compare the duration of active phase of labor in women with spontaneous or induced start of labor. MATERIAL AND METHODS: An observational cohort study was performed at Stavanger University Hospital in Norway between January 2010 and December 2013. During the study period 19 524 women delivered. Data for the study were collected from an electronic birth journal. Women with previous cesarean section, multiple pregnancy, breech or transverse lie, preterm labor or prelabor cesarean section were excluded. Analyses were stratified between nulliparous and parous women. Active phase of labor was defined when contractions were regular, with cervix effaced and dilated 4 cm. The main outcome measure was duration of active phase of labor. RESULTS: The active phase was longer in induced labors than in labors with spontaneous onset in nulliparous women. The estimated median duration using survival analyses was 433 min (95% confidence interval 419-446) in spontaneous vs. 541 min (95% confidence interval 502-580) in induced labors [unadjusted hazard ratio 0.76 (95% confidence interval 0.71-0.82) and adjusted hazard ratio 0.88 (95% confidence interval 0.82-0.95)]. In parous women, a one minus survival plot showed that induced labors had shorter duration before six hours in active labor, but after six hours, induced labors had longer duration. The overall difference in parous women was small and probably of little clinical importance. CONCLUSION: The active phase of labor was longer in induced than in spontaneous labors in nulliparous women.
