HUBUNGAN FREKUENSI KONSUMSI BAHAN MAKANAN SUMBER PROTEIN DAN ZAT BESI DENGAN KADAR HEMOGLOBIN PADA REMAJA PUTRI DI SMP NEGERI 3 DUMOGA

Abstract

Anemia in adolescent girls is a common nutritional problem caused by inadequate intake of essential nutrients such as protein and iron. An unbalanced diet and low frequency of nutritious food consumption are among the main factors contributing to low hemoglobin levels. This study 
aims to determine the relationship between the frequency of consumption of protein and iron rich foods and hemoglobin levels in female adolescents. This research used a quantitative approach with an analytical observational design and a cross-sectional study method. The subjects were 30 female students aged 12–15 years, selected through proportional random sampling from SMP Negeri 3 Dumoga. Food consumption frequency was assessed using a Food Frequency Questionnaire (FFQ), while hemoglobin levels were measured with a digital hemoglobinometer. Data analysis was performed using univariate and bivariate methods with 
Spearman’s rho test. The results showed that most adolescent girls had a moderate frequency of consuming protein and iron-rich foods (80%) and normal hemoglobin levels (83.3%). The Spearman’s rho statistical test indicated a significant relationship between the frequency of consumption of protein and iron-rich foods and hemoglobin levels (sig 2-tailed = 0.000). Thus, the more frequently adolescents consume iron- and protein-rich foods, the greater the likelihood of having normal hemoglobin levels.
