Urinary incontinence is an issue that a lot of women face nowadays and up to 28% of women had dealt with or has this issue. Urinary Incontinence results from disorders that affect the lower urinary tract or diseases that affect the neurological supply or the central nervous system as a whole. The prevalence of urinary incontinence among young women is 20-30%, and it tends to gradually increase up to 40% among older women. and with parity being a major agent in the pathophysiology of urinary incontinence specifically Stress Urinary Incontinence along with age. That's why in this study, we aimed to assess the relationship between Multiparity and UI in Saudi Arabia and to identify the local risk factors in which Saudi Arabian women may develop UI in relation to the number of giving births.

cross-sectional study was conducted using a validated Arabic version of Urogenital Distress Inventory-6 (UDI-6), Incontinence Impact Questionnaire-7 (IIQ-7) short form. The number of giving births and mode of delivery were collected to assess the relationship with the degree of incontinence if present. Data analysis of the study variables was done using SPSS26. The Chi-square test was used to assess the relationship between parity and incontinence degree.

The sample included 550 women aged 18 and above: 29 are Non-Multiparous women (NMP)(0 or 1 birth) (5.3%) and 501 Multiparous women(MP) (had 2 or more births)(91.1%). The MP group had a higher score, compared to the NMP group, for UI by Urogenital Distress Inventory-6 (UDI-6), and Incontinence Impact Questionnaire-7 (IIQ-7) (P-value: 0.01%) Incontinence was found to be present in 77.5% of the sample, 68.7% 64.5% Urgency and Stress UI, respectively.

The mentioned 501 Multiparous women(MP) (had 2 or more births) who represented (91.1%)of the sample were reported to have Urgency UI and Stress UI (68.7%, and 64.5% respectively). the Nonmultiparus had Stress Urinary Incontinence (17/49) 34.69% vs multiparous had stress urinary incontinence 325/501(64.47%) (p=0.000038). on another note, the Nonmultiparous who have urgency urinary incontinence were 25/51 (51.02%) vs. the Multiparus who have SUi are (334/501) (p=0.012127).and upon a further interpretation of the results and asking about the mode of delivery 62.7% of them reported having only vaginal delivery while 25.5% had only C-Section and the remaining had both modes of delivery, in which we found that there is a high association between vaginal delivery and developing UI. Moreover, upon asking about the parity 29.3% have had 6 or more deliveries while 20.5% have had only 5 deliveries. Therefore, the higher the parity the more likelihood that Patients will develop UI.

UI is common among Multiparous women. And the risk increases with the number of giving births. Therefore, health workers should consider the likelihood of UI occurrence in Multiparas women, and proper management and further screening and prevention must be taken into consideration after delivery especially should be taken into consideration.
