<![CDATA[Anemia remains a major public health concern among adolescent girls because it can negatively affect physical growth, cognitive development, learning capacity, reproductive health, and future productivity. According to the 2023 Indonesian Health Survey (Survei Kesehatan Indonesia/SKI), the prevalence of anemia among adolescent girls reached 18%. One of the factors suspected to be associated with anemia is inadequate dietary intake of iron-rich foods. This study aimed to determine the relationship between dietary iron source intake and the incidence of anemia among adolescent girls at SMP N 1 Godean. This analytical observational study employed a cross-sectional design. A total of 88 adolescent girls were selected using a purposive sampling technique. Dietary iron source intake was assessed using a Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ), while hemoglobin concentration was measured using capillary blood samples with an EasyTouch GCHb device. Data were analyzed using univariate analysis and Fisher's Exact test, with a significance level of (p < 0.05). Most respondents had inadequate dietary iron source intake (90.91%) and were not anemic (88.64%), whereas the prevalence of anemia was 11.36%. The bivariate analysis showed no statistically significant association between dietary iron source intake and the incidence of anemia among adolescent girls (p = 0.224). There was no statistically significant relationship between dietary iron source intake and the incidence of anemia among adolescent girls at SMP N 1 Godean. The proportion of participants with inadequate dietary iron source intake was high (90.91%). Hemoglobin concentration was measured once during data collection, and anemia status was defined using the hemoglobin cutoff of <12 g/dL. Other potential determinants of anemia were not directly measured in this study.]]>
