Prevalence of urinary incontinence in pregnant and postpartum women in the Democratic Republic of Congo

Development and external validation of clinical predictive model for stress urinary incontinence in Chinese women : a multicenter retrospective study

BACKGROUND

Stress urinary incontinence (SUI), the prevalent form of urinary incontinence, significantly impairs women's quality of life. This study aims to create a visual nomogram to estimate the risk of SUI within one year postpartum for early intervention in high-risk Chinese women.

METHODS

We recruited 1,531 postpartum women who gave birth at two hospitals in Kunshan City from 2021 to 2022. Delivery details were meticulously extracted from the hospitals' medical records system, while one-year postpartum follow-ups were conducted via phone surveys specifically designed to ascertain SUI status. Utilizing data from one hospital as the training set, logistic regression analysis was performed to pinpoint significant factors and subsequently construct the nomogram. To ensure robustness, an independent dataset sourced from the second hospital served as the external validation cohort. The model's performance was rigorously evaluated using calibration plots, ROC curves, AUC values, and DCA curves.

RESULTS

The study population was 1,125 women. The SUI incidence within one year postpartum was 26% (293/1125). According to the regression analysis, height, pre-pregnancy BMI, method of induction, mode of delivery, perineal condition, neonatal weight, SUI during pregnancy, and SUI during the first pregnancy were incorporated into the nomogram. The AUC of the nomogram was 0.829 (95% CI 0.790-0.867), and the external validation set was 0.746 (95% CI 0.689-0.804). Subgroup analysis based on parity showed good discrimination. The calibration curve indicated concordance. The DCA curve showed a significant net benefit.

CONCLUSION

Drawing from real-world data, we have successfully developed an SUI predictive model tailored for postpartum Chinese women. Upon successful external validation, this model holds immense potential as an effective screening tool for SUI, enabling timely interventions and ultimately may improve women's quality of life.

Epidemiological Profile and Attitudes of Pregnant Women Toward Urinary Incontinence: A Single-Center Cross-Sectional Study

OBJECTIVE

The objective was to highlight the epidemiological and clinical profile of urinary incontinence in pregnant women during the first trimester and to determine their knowledge and attitudes toward this condition in Kinshasa.

METHODS

We carried out a descriptive cross-sectional study among 127 pregnant women who came for prenatal consultations in the first trimester from January to March 2022 at the LISANGA Medical Centre in Kinshasa. A questionnaire was developed containing the Urinary Symptom Profile (USP) scale. Kolmogorov-Smirnov normality tests were used to determine the normality of the distribution of the study variables. Inferential statistics were performed. The significance level was 0.05.

RESULTS

The mean age was 29.7±5.5 years. Thirty-eight women (29.9%) were primigravida. The median age of pregnancy was 6 weeks of amenorrhoea. The prevalence of urinary incontinence was 73.2%, with 31.2% of urge urinary incontinence and 16.1% of stress incontinence. In 61.4% of cases, overactive bladder was associated with urinary incontinence. Among the incontinent pregnant women, 3.2% had consulted a doctor while accepting that this condition is a health problem, 13.4% knew they had a pelvic floor muscle, 4.7% had knowledge of its rehabilitation, and 8.7% had benefited from gymnastics during pregnancy.

CONCLUSIONS

Urinary incontinence was frequent in the first trimester of pregnancy with a predominance of urgency. It was hardly discussed during prenatal consultations and pregnant women were not aware of the pelvic floor muscle, its rehabilitation, and of gymnastics during pregnancy.

Epidemiological trends and risk factors related to lower urinary tract symptoms around childbirth: a one-year prospective study

BACKGROUND

Lower urinary tract symptoms (LUTS) are prevalent and distressing concerns for women worldwide. The prevalence of LUTS reaches the first peak during pregnancy and postnatal period. However, less attention has been paid to LUTS around childbirth and little progress has been made in the prevention of LUTS. Understanding the epidemiological characteristics of LUTS around childbirth would inform decision making for health care providers and perinatal women in the prevention of LUTS. The study aims to investigate the epidemiological trends and associated risk factors related to LUTS around childbirth.

METHODS

Pregnant women were consecutively enrolled during pregnancy in the obstetrical wards of a tertiary hospital and followed up at 6-8 weeks and one year postpartum through a prospective design. Urinary incontinence was assessed with the International Consultation on Incontinence Modular Questionnaire-Urinary Incontinence Short Form. Other symptoms were measured with questions based on definitions of the International Incontinence Society. Multiple logistic regression was used to examine the risk factors for LUTS including urinary incontinence, increased daytime frequency, nocturia and urgency. The report followed the STROBE statement.

RESULTS

A total of 1243 pregnant women participated in this study. The prevalence of at least one type of storage symptoms was 94%, 55% and 35% in late pregnancy, at 6-8 weeks and one year postpartum, respectively. The prevalence of urinary incontinence remained at 21% within one year postpartum. The majority of the participants suffered from mild to moderate urinary incontinence. Age, job, BMI before pregnancy, gestational diabetes mellitus, urinary tract infection history, previous history of LUTS, age at first birth and birth mode were predictors of LUTS one year postpartum.

CONCLUSION

LUTS were highly prevalent during pregnancy and postnatal period. The prevalence of urinary incontinence was more stable than that of other LUTS within one year postpartum. Women aged more than 35 years, engaging in manual work, with gestational diabetes mellitus, with a history of urinary tract infection and LUTS, with advanced age at first birth and vaginal delivery were more likely to suffer from LUTS postpartum. The findings provided a novel and deep insight into the epidemiological trends and related risk factors of LUTS around childbirth.

Sitting on the fence: A qualitative study of perceptions regarding pelvic floor muscle training among pregnant women with urinary incontinence

Objectives

To explore the perceptions of pregnant women with urinary incontinence toward pelvic floor muscle training (PFMT).

Methods

Semi-structured personal interviews were used to collect data. Pregnant women with urinary incontinence and no contraindications to PFMT were recruited for semi-structured interviews in the Outpatient Department of Obstetrics in a Class A tertiary hospital in Shenzhen from October to November 2021. Purposive sampling was performed, and Braun & Clarke thematic analysis was used for the data analysis.

Results

Sixteen pregnant women with urinary incontinence and a mean age of (30.81 ± 3.66) years participated in the interview. "Sitting on the fence" was the predominant theme acquired after analysis. Pregnant women had contradictory attitudes toward PFMT. A total of four themes and nine sub-themes have been extracted: "It is normal and does not really matter" (normalized urinary incontinence, insufficient attention to PFMT); "There is nothing I can do" (insufficient subjective motivations, limitation of objective conditions, lack of social support); "We have to take care of ourselves" (the increasing self-care awareness, emerging autonomous motivation to practice PFMT); "Training should be guaranteed" (requiring the guidance, suggestions, and surveillance of healthcare professionals; requiring the perceptive benefits).

Conclusions

This study reveals varying attitudes towards PFMT among pregnant women with urinary incontinence. To better promote pregnant women's engagement in PFMT, it is necessary to provide professional guidance, increase self-care awareness, improve social support, and emphasize the benefits of PFMT.

Transcriptomic Profiling of Rectus Abdominis Muscle in Women with Gestational Diabetes-Induced Myopathy: Characterization of Pathophysiology and Potential Muscle Biomarkers of Pregnancy-Specific Urinary Incontinence

Gestational diabetes mellitus (GDM) is recognized as a "window of opportunity" for the future prediction of such complications as type 2 diabetes mellitus and pelvic floor muscle disorders, including urinary incontinence and genitourinary dysfunction. Translational studies have reported that pelvic floor muscle disorders are due to a GDM-induced-myopathy (GDiM) of the pelvic floor muscle and rectus abdominis muscle (RAM). We now describe the transcriptome profiling of the RAM obtained by Cesarean section from GDM and non-GDM women with and without pregnancy-specific urinary incontinence (PSUI). We identified 650 genes in total, and the differentially expressed genes were defined by comparing three control groups to the GDM with PSUI group (GDiM). Enrichment analysis showed that GDM with PSUI was associated with decreased gene expression related to muscle structure and muscle protein synthesis, the reduced ability of muscle fibers to ameliorate muscle damage, and the altered the maintenance and generation of energy through glycogenesis. Potential genetic muscle biomarkers were validated by RT-PCR, and their relationship to the pathophysiology of the disease was verified. These findings help elucidate the molecular mechanisms of GDiM and will promote the development of innovative interventions to prevent and treat complications such as post-GDM urinary incontinence.

Urinary incontinence in pregnant women and its impact on health-related quality of life

Background

Urinary incontinence is a common and distressing condition affecting women worldwide. However, urinary incontinence during pregnancy was less studied. The study aims to investigate the prevalence and risk factors of urinary incontinence during pregnancy, its impact on health-related quality of life as well as associated help-seeking behavior.

Methods

Eligible women were enrolled in the obstetric wards of a tertiary maternity hospital. Urinary incontinence, generic and specific health-related quality of life were assessed using the International Consultation on Incontinence Modular Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF), the 12-Item Short Form Health Survey version 2 (SF-12v2), Urogenital Distress Inventory short form (UDI-6) and Incontinence Impact Questionnaire short form (IIQ-7), respectively. Multiple logistic regression and multiple linear regression analysis were used to examine risk factors of urinary incontinence during pregnancy and the impact of incontinence on health-related quality of life of pregnant women, respectively.

Results

A total of 1243 women were enrolled in the study. The prevalence of urinary incontinence during pregnancy was 52.0%. Most women suffered from mild or moderate incontinence. Five risk factors were identified by multiple logistic regression. Urinary incontinence before pregnancy was the strongest predictor for incontinence during pregnancy (OR = 4.178, 95% CI = 2.690–6.490), followed by history of vaginal birth, coffee consumption, childhood enuresis and history of urinary tract infection. Urinary incontinence had significant impact on health-related quality of life during pregnancy. Only 14.8% of pregnant women sought professional help for urinary symptoms.

Conclusions

Urinary incontinence was highly prevalent in pregnant women, with a broad detrimental effect on health-related quality of life. Five factors were confirmed to be associated with increasing the risk of developing urinary incontinence during pregnancy. The help-seeking behavior during pregnancy was discouraging. Targeted interventions are warranted to facilitate the prevention of urinary incontinence and improvement of health-related quality of life in pregnant women.
