Table 1 Screening questions

1. First, ask the pregnant woman if she experiences urinary incontinence

Do you have urine leakage?

• Instruct the pregnant woman to answer "never", "sometimes", or "always"

➢ When the pregnant woman answers "always" or "sometimes", it means the pregnant woman experiences urinary incontinence. So, continuing with the next question

➢ When the patient answers "never", it means there is no urinary incontinence and the Q&A is over

2. Next, ask the patient about the type of urinary incontinence

(1) Do you leak urine when coughing, sneezing, laughing, lifting heavy objects, or exercising?

• Instruct the patient to answer "always", "sometimes" or "never"

➢ When the pregnant woman answers "always" or "sometimes", it means that the pregnant woman experiences stress urinary incontinence. So, moving on to the next question

➢ When the patient answers "never", it means the absence of stress urinary incontinence and then ends the Q&A

(2) Do you leak urine on your way to the toilet?

• Instruct the patient to answer "always", "sometimes" or "never"

➢ When the patient answers "always" or "sometimes", it means that the patient experiences urge urinary incontinence. If stress urinary incontinence and urge urinary incontinence are both present, the patient experiences mixed urinary incontinence. The patient was excluded from this study

➢ When the patient answers "never", it means the absence of urge urinary incontinence, and then the patient is invited to participate in the study
