Prevalence of overactive bladder syndrome (OABS) among women with gynaecological problems and its risk factors in a tertiary hospital, Negeri Sembilan, Malaysia: Implication for primary healthcare providers.

OBJECTIVE

The objective of this paper was to determine the prevalence of overactive bladder syndrome (OABS) and its risk factors among patients with other gynaecological problems.

METHODS

This study was conducted on women aged more than 18 years who attended the gynaecology clinic for various diagnoses other than urinary problems at a tertiary hospital in Negeri Sembilan, Malaysia, for a period of 6 months. Data on patient's profile, symptoms and risk factors for overactive bladder (OAB) were prospectively collected using a structured questionnaire adapted from ICIQ (international consultation on incontinence questionnaire). Exclusion criteria included patients with confirmed diagnosis of stress incontinence or OAB, neurological impairment, gynaecological malignancy and those with a previous history of pelvic radiation. Chi-square test and logistic regression test were used in the statistical analysis. We presented the odds ratio (OR) and 95% confidence interval for each of the OAB symptoms with p-value of 0.05.

RESULTS

The prevalence of OAB among the patients (n = 573) in this study was 19.1%. History of giving births to macrosomic babies and presence of utero-vaginal prolapse (UVP) were shown to be significantly associated with OAB in the multivariate analysis. Other factors were advanced age, high parity and menopausal for more than 5 years. More than half of the patients with the symptoms of OAB did not seek treatment, as they did not think it is necessary.

CONCLUSION

It is found that the prevalence of OAB is similar with many other studies conducted elsewhere. It was found to be multifactorial, but was highly significantly related with the presence of UVP, especially cystocoele and history of giving births to macrosomic babies.
