Factors related to the incidence of anemia in adolescent girls at Senior High School X Kendari in 2025

Anemia is one of the most common health problems among adolescent girls and can affect their growth, development, and learning performance. This study aimed to determine the factors associated with the incidence of anemia among adolescent girls at Senior High School X Kendari in 2025. This research applied an observational analytic method with a cross-sectional design. Data were collected through structured questionnaires and measurements of hemoglobin (Hb) levels using a digital haemometer, as well as weight and height measurements using scales and a microtoise. The study population consisted of all grade X female students (262 individuals), with a sample of 159 respondents selected using the proportionate stratified random sampling technique. Data were analyzed bivariately using the Chi-Square test. The results showed that out of 159 respondents, 52 (32.7%) respondents experienced anemia, while 107 (67.3%) respondents did not. Statistical analysis revealed significant associations between physical activity (p=0.015), dietary patterns (p=0.000), and sleep quality (p=0.003) with the incidence of anemia, while disease history (p=1.000) was not significantly related. Thus, it can be concluded that physical activity, dietary patterns, and sleep quality are associated with anemia among female adolescents, while disease history is not. Schools are expected to enhance nutrition education, promote healthy eating habits, and improve students' awareness of adequate rest while strengthening the iron tablet supplementation program in collaboration with local health centers.
