The Effect of Peer Education on Genital Hygiene Behaviors and Self-Care Power in Adolescent Girls

Genital infections are the most common cause of hospital admissions for reproductive health. While these infections are treatable and preventable, they can negatively impact women's health due to their complications. Genital infections are among the most preventable diseases, but due to their prevalence and complications, they pose a significant problem for women's health. Genital infections are both preventable and treatable, but they are a major problem frequently encountered among women aged 15-49. Women most frequently present to gynecology clinics with complaints of itching and vaginal discharge. Genital infections cause various complications related to reproductive health. Genital infections can negatively impact a woman's fertility, sexual life, family life, and mental health, impairing her quality of life, and can also lead to social isolation. Literature reports that approximately one million women worldwide experience genital infections annually, and 75% of them have a history of vaginal infections. Studies conducted in Turkey indicate that women have inadequate/incorrect genital hygiene practices and a low level of awareness.

Factors such as the anatomical structure of the female genital system, inadequate knowledge about preventing genital infections, low socioeconomic status, inadequate/incorrect perineal and menstrual hygiene, not washing hands before and after using the toilet, and not using appropriate underwear contribute to genital infections. The main factor that can be changed in preventing genital infections is deficiencies in genital and menstrual hygiene. Genital hygiene encompasses many different hygiene behaviors necessary to protect the organs in the genital area from infectious agents, maintain body health, and improve functional health conditions. Ensuring genital hygiene is of great importance in protecting and improving women's health. When genital hygiene is not given the necessary attention, the tendency to genital infection increases, and if genital infection is left untreated, a woman's fertility is affected. Therefore, correctly implemented genital hygiene behaviors are the most critical step in preventing genital infections and their consequences. When studies conducted in our country are examined; As a result of lack of knowledge and incorrect practices about genital hygiene behaviors, women are seen to present to outpatient clinics with complaints of genital discharge, and their risk of vaginal infection increases. Therefore, it is emphasized that education focusing on correct genital hygiene habits has the potential to reduce this risk. Nurses, as part of the healthcare system, play a critical role in improving the health behaviors of both individuals and society through the educational seminars they conduct. This type of health education provided to women positively affects not only their personal health but also public health. Studies have shown that education covering correct genital hygiene practices can contribute to women's health, strengthening their self-care ability, physical health, mental health, and social relationships. There are many "self-care" practices that people perform to maintain their health. Genital hygiene care has an important place among these. Good self-care practices positively impact quality of life through factors such as preventing illness, providing a sense of independence and control, and contributing to personal development. However, this relationship can vary from person to person depending on individual experiences. Genital infections reduce individuals' standards of living and negatively affect their self-care ability. Increasing self-care ability, one of the factors that plays a role in preventing genital infections, is crucial. Therefore, this study aimed to examine the effects of peer education provided to young girls on genital hygiene behavior and self-care ability.

Research Type: This is a pretest-posttest randomized controlled trial. The study was conducted with female students studying at Kahramanmaraş Sütçü İmam University Technical Vocational School between the dates of the study.

Research Universe and Sample: The study population consists of female students studying at Kahramanmaraş Sütçü İmam University (KSU) Technical Sciences Vocational School. The study sample will consist of students who were continuing their education between October and November 2025, agreed to participate in the study, signed the consent form, and met the inclusion criteria.

The sample size of the study was calculated based on the findings of the randomized controlled trial by Sabancı Baransel et al. (2024). In this study, a significant increase in the total score of the Genital Hygiene Behaviors Inventory was found in the intervention group, and the difference between the groups at the posttest was found to be large effect size (Cohen's d ≈ 1.0-1.2). In light of these data, a power analysis was conducted for our study using ANCOVA analysis in a pretest-posttest design between two groups (experimental and control) using G*Power 3.1. Based on the criteria of a medium-to-large effect size (Cohen's d = 0.80), 95% confidence level (α = 0.05), and 80% power (1-β = 0.80), a minimum of 30 participants per group was calculated. Considering a possible 20% sample loss, a total of 72 students were targeted, with 36 participants per group.
