Item Sexual function, delivery mode history, pelvic floor muscle exercises and incontinence : a cross-sectional study six years postpartum(Wiley Interscience, 2008-06-03) Dean, Nicola; Wilson, Don; Herbison, Peter; Glazener, Cathryn Margaret Anne; Aung, Thiri; MacArthur, ChristineBackground: There is controversy over the effect of mode of delivery, pelvic floor muscle exercises (PFME), incontinence and sexual function. Aim: To investigate the relationship of sexual function with delivery mode history, PFMEs and incontinence. Methods: This was a cross-sectional postal survey of women, six years post-partum, who had given birth in maternity units in Aberdeen, Birmingham and Dunedin and had answered a previous questionnaire. Each sexual function question was analysed separately by ANOVA. Results: At six years post-index delivery, 4214 women responded, of whom 2765 (65%) answered the optional ten sexual function questions. Although there was little association between delivery mode history and most sexual function questions, women who had delivered exclusively by caesarean section scored significantly better on the questions relating to their perception of vaginal tone for their own (P-value < 0.0001) and partner's (P-value 0.002) sexual satisfaction, especially when compared with women who had had vaginal and instrumental deliveries. Women who reported that they were currently performing PFME scored significantly better on seven questions. Women with urinary or faecal incontinence scored significantly poorer on all sexual function questions. Conclusions: Mode of delivery history appeared to have minimal effect on sexual function. Current PFME performance was positively associated with most aspects of sexual function, however, all aspects were negatively associated with urinary and faecal incontinence.Item New postnatal urinary incontinence: obstetric and other risk factors in primparae.(Blackwell Publishing, 2006-02) Glazener, Cathryn Margaret Anne; Herbison, G.P; MacArthur, C; Lancashire, R; McGee, M; Grant, Adrian MaxwellObjective To identify obstetric and other risk factors for urinary incontinence which occurs during pregnancy or after childbirth. Design Questionnaire survey of women. Setting Maternity units in Aberdeen (Scotland), Birmingham (England) and Dunedin (New Zealand). Population 3405 primiparous women with singleton births delivered during one year. Methods Questionnaire responses and obstetric casenote data were analysed using multivariate analysis to identify associations with urinary incontinence. Main outcome measures Urinary incontinence at three months after delivery first starting in pregnancy or after birth. Results The prevalence of urinary incontinence was 29%. New incontinence first beginning after delivery was associated with higher maternal age (oldest versus youngest group, odds ratio, OR 2.02, 95% CI 1.35 to 3.02); and method of delivery (caesarean section versus spontaneous vaginal delivery, OR 0.28, 95% CI 0.19 to 0.41). There were no significant associations with forceps delivery (OR 1.18, 95% CI 0.92 to 1.51) or vacuum delivery (OR 1.16, 95% CI 0.83 to 1.63). Incontinence first occurring during pregnancy and still present at three months was associated with higher maternal body mass index (BMI > 25, OR 1.68, 95% CI 1.16 to 2.43), and heavier babies (birthweight in top quartile, OR 1.56, 95% CI 1.12 to 2.19). In these women, caesarean section was associated with less incontinence (OR 0.39, 95% CI 0.27 to 0.58) but incontinence was not associated with age. Conclusions Women have less urinary incontinence after a first delivery by caesarean section whether or not that first starts during pregnancy. Older maternal age was associated with new postnatal incontinence, and higher body mass index and heavier babies with incontinence first starting during pregnancy. The effect of further deliveries may modify these findings.Item Persistent urinary incontinence and delivery mode history: a six-year longitudinal study.(Blackwell Publishing, 2006-02) MacArthur, C; Glazener, Cathryn Margaret Anne; Wilson, P.D; Lancashire, R; Herbison, G.P; Grant, Adrian MaxwellObjective: To investigate the prevalence of persistent and long term postpartum urinary incontinence and associations with mode of first and subsequent delivery. Setting: Maternity units in Aberdeen (Scotland), Birmingham (England) and Dunedin (New Zealand). Design: Longitudinal study Population: 4214 women who returned postal questionnaires 3 months and 6 years after the index birth. Methods: Symptom data were obtained from both questionnaires and obstetric data from case-notes for the index birth and the second questionnaire for subsequent births. Logistic regression investigated the independent effects of mode of first delivery and delivery mode history. Main outcome measures: Urinary incontinence – persistent (at 3 months and 6 years after index birth) and long-term (at 6 years after index birth). Results: The prevalence of persistent urinary incontinence was 24%. Delivering exclusively by Caesarean section was associated with both less persistent (OR= 0.46, 95% CI 0.32 to 0.68) and long term urinary incontinence (OR=0.50, 95% CI 0.40 to 0.63). Caesarean section birth in addition to vaginal delivery however was not associated with significantly less persistent incontinence (OR 0.93, 95%CI 0.67 to 1.29). There were no significant associations between persistent or long-term urinary incontinence and forceps or vacuum extraction delivery. Other significantly associated factors were increasing number of births and older maternal age. Conclusions: The risk of persistent and long term urinary incontinence is significantly lower following Caesarean section deliveries but not if there is another vaginal birth. Even when delivering exclusively by Caesarean section, the prevalence of persistent symptoms (14%) is still high.Item Incontinence-specific quality of life measures used in trials of treatments for female urinary incontinence: a systematic review.(Springer, 2006-05) Ross, S; Soroka, D; Karahalios, A; Glazener, Cathryn Margaret Anne; Hay-Smith, E. J. C.; Drutz, H.PThis systematic review examined the use of incontinence-specific QOL measures in clinical trials of female incontinence treatments, and systematically evaluated their quality using a standard checklist. Of 61 trials included in the review, 58 (95.1%) used an incontinence-specific QOL measure. The most commonly used were IIQ (19 papers), I-QoL (12 papers) and UDI (9 papers). Eleven papers (18.0%) used measures which were not referenced or were developed specifically for the study. The eight QOL measures identified had good clinical face validity and measurement properties. We advise researchers to evaluate carefully the needs of their specific study, and select the QOL measure that is most appropriate in terms of validity, utility and relevance, and discourage the development of new measures. Until better evidence is available on the validity and comparability of measures, we recommend that researchers consider using IIQ or I-QOL with or without UDI in trials of incontinence treatments.
