Vaginal discharge is one of the most common reproductive health problems experienced by women of childbearing age (WUS). Lack of knowledge about vaginal discharge can lead women to perceive it as normal, thus avoiding preventive measures or health checkups. Health education using leaflets is one method that can increase WUS knowledge because it is simple, practical, and easy to understand. This study aims to determine the effect of leaflets on WUS knowledge about vaginal discharge at the Sawah Lebar Community Health Center in Bengkulu City. This study used a quantitative method with a pre-experimental design using a one-group pretest-posttest design. The population was all 6,558 women of childbearing age in the Sawah Lebar Community Health Center's work area. A sample of 30 respondents was drawn using a simple purposive sampling technique. Data collection was conducted using a questionnaire. Data analysis used a paired sample t-test. The results showed that before receiving the leaflets, most respondents had poor knowledge (19 respondents (63.3%), with an average knowledge score of 51.17). After being given the leaflets, respondents' knowledge increased, with an average score of 76.33, and the majority of respondents (18 respondents, 60.0%) had a sufficient level of knowledge. Statistical test results showed a p-value of 0.000 (p < 0.05), indicating that leaflets significantly increased women of childbearing age's knowledge about vaginal discharge. It was concluded that health education using leaflets significantly increased knowledge about vaginal discharge among women of childbearing age. Therefore, leaflets are expected to be utilized as a promotional and preventive measure by health workers to improve reproductive health knowledge among women of childbearing age.
