Abstract

This study aims to examine the relationship between adolescents' knowledge about HIV/AIDS and HIV/AIDS prevention behavior at SMA Swasta Katolik Santa Maria Medan. Adolescents remain a high-risk group for HIV/AIDS transmission due to limited reproductive-health knowledge and exposure to risky behaviors, while national data show that Medan City records the highest number of HIV cases in North Sumatra Province. This research employed a descriptive-correlational design with a cross-sectional approach. The population consisted of 294 students in grades X–XII, and 75 respondents were recruited using the Slovin formula with a purposive sampling technique. Data were collected using a closed-ended questionnaire adapted from a previously validated instrument, then analyzed through univariate and bivariate analyses. The results showed that most respondents were female (54.7%) and aged 17 years (69.3%). The majority of respondents had a moderate level of knowledge about HIV/AIDS (58.6%) and moderate prevention behavior (66.6%). Bivariate analysis produced a correlation coefficient of 0.249 with a p-value of 0.045 (<0.05), indicating a statistically significant but weak positive relationship between adolescents' knowledge and HIV/AIDS prevention behavior. These findings imply that continuous and systematic health-education programs at school are needed to strengthen adolescents' knowledge and preventive behavior toward HIV/AIDS.

Abstract

Vaginal discharge (fluor albus) is one of the most common reproductive health problems experienced by adolescent girls. Inadequate knowledge of genital hygiene may increase the risk of pathological discharge and affect both physical and psychological well-being. This study aimed to analyze the relationship between knowledge of reproductive organ hygiene and the prevention of vaginal discharge among ninth-grade female students at SMP Negeri 19 Medan in 2026. A quantitative correlational design with a cross-sectional approach was used. The sample consisted of 56 respondents drawn from a population of 128 students using purposive sampling. Data were collected through structured questionnaires and analyzed univariately and bivariately using the Spearman Rank test at α = 0.05. The results showed that knowledge was mostly in the sufficient (42.9%) and good (39.3%) categories, while prevention behavior was mostly in the sufficient category (55.4%). The Spearman Rank test yielded p = 0.013 (< 0.05) and r = 0.329, indicating a statistically significant, positive, and weak correlation. Better knowledge tended to be accompanied by better preventive behavior. Schools and health workers are encouraged to provide continuous reproductive health education to strengthen preventive behavior.
