Factors associated with urinary incontinence among pregnant women in Yaoundé
This multicenter cross-sectional study in Yaoundé, Cameroon, identified that older maternal age, specific occupations, higher parity, elevated body mass index, and advancing gestation are independent factors associated with urinary incontinence, with mixed incontinence being the most prevalent subtype among pregnant women.

For many women, the experience of pregnancy is a time of profound physical change, but it can also bring unexpected challenges to the bladder. Urinary incontinence, the involuntary leakage of urine, is a common occurrence during this period. It happens when the muscles and tissues that normally hold urine in place are overwhelmed by the shifting hormones, the growing weight of the baby, and the pressure of the expanding uterus. While this condition can limit a woman's ability to exercise, socialize, or sleep, it often goes unspoken. Many expectant mothers assume that leaking a little is just a normal part of carrying a child, or they feel too embarrassed to mention it to their doctors. This silence is particularly prevalent in Central Africa, where routine screening for these symptoms is not yet a standard part of prenatal care. Understanding who is most likely to experience this leakage, and why, is the first step toward helping women manage their health with dignity and confidence.
In Yaoundé, the capital city of Cameroon, a team of researchers set out to map the landscape of this issue. They conducted a detailed study involving three different maternity facilities, recruiting pregnant women who were already receiving care. The researchers did not simply ask if women had leakage; they used a specific set of questions to sort the problem into three distinct categories. Some women experienced stress incontinence, where a cough, sneeze, or laugh caused a leak. Others felt urgency incontinence, a sudden, overwhelming need to rush to the toilet. A third group suffered from a mix of both. The study focused on comparing 163 women who reported these symptoms with 163 women who did not, looking closely at their ages, jobs, family histories, body weights, and how far along they were in their pregnancies.
The results painted a clear picture of the factors that increase the likelihood of leakage. The most common type of incontinence found among the symptomatic women was the mixed type, where both stress and urgency symptoms occurred together, followed by stress incontinence and then urgency incontinence. The study identified several powerful predictors. Age played a significant role; women between the ages of 36 and 42 were far more likely to experience leakage than younger women. The number of previous births a woman had also mattered greatly. Those who had given birth two to three times before, or four to five times, faced much higher odds of incontinence compared to those with fewer previous deliveries.
Physical factors were equally important. Women who were overweight or obese were significantly more likely to report symptoms than those with a normal body weight. The timing within the pregnancy also mattered; as women moved from the first trimester into the second and third, the likelihood of leakage increased sharply. The researchers also found that a woman's occupation was linked to her risk. Women working as traders or civil servants reported higher rates of incontinence compared to those who were unemployed or students. This connection likely reflects the physical demands of these jobs, such as standing for long periods or having limited access to restrooms, rather than the job title itself.
The study was designed to uncover these specific associations, but it did have a specific boundary. Because the researchers recruited an equal number of women with and without symptoms, the study cannot tell us exactly how common urinary incontinence is among all pregnant women in Yaoundé. It tells us who is at higher risk, but not the total size of the problem in the general population. Despite this limitation, the findings offer a practical path forward. The authors suggest that prenatal care in the region should evolve to include direct, respectful questions about bladder leakage. By identifying women who are older, have had multiple births, carry extra weight, or are in the later stages of pregnancy, doctors can offer early support. This support could include advice on managing weight and, crucially, access to supervised exercises that strengthen the pelvic floor muscles. These simple interventions, introduced before symptoms become severe, could help women navigate their pregnancies with greater comfort and control.
