Abstract

THE RELATIONSHIP BETWEEN BODY MASS INDEX (BMI) AND HEMOGLOBIN (Hb) LEVELS IN MEDICAL LABORATORY TECHNOLOGY STUDENTS AT THE DENPASAR MINISTRY OF HEALTH POLYTECHNIC ABSTRACT Background: Body Mass Index (BMI) is a simple anthropometric indicator for evaluating an individual's nutritional status, which has the potential to influence blood hemoglobin levels. Nutritional imbalances in students can trigger disruptions in hemoglobin levels, such as anemia. Aims: The aims to analyze the relationship between BMI and hemoglobin levels among students in the Medical Laboratory Technology Department at Poltekkes Kemenkes Denpasar. Methods: This observational study employed a cross-sectional approach, conducted from October 2025 to April 2026. The sample consisted of 39 students selected using non-probability purposive sampling. Data were collected through BMI measurements, hemoglobin level examinations using the cyanmethemoglobin method, and a dietary questionnaire. Data analysis was performed using the Spearman Rank test. Results: The study found that respondents with underweight BMI had low hemoglobin levels at 84,6%. Statistical analysis revealed a significant relationship between BMI and hemoglobin levels (p=0.000), with a strong positive correlation strength (r=0.606). Conclusion There is a significant relationship between body mass index and hemoglobin levels among students in the Medical Laboratory Technology Department at Poltekkes Kemenkes Denpasar. Keywords: Body Mass Index; Hemoglobin HUBUNGAN INDEKS MASSA TUBUH (IMT) DENGAN KADAR HEMOGLOBIN PADA MAHASISWA JURUSAN TEKNOLOGI LABORATORIUM MEDIS POLTEKKES KEMENKES DENPASAR ABSTRAK Latar Belakang Indeks massa tubuh (IMT) merupakan indikator antropometri sederhana untuk mengevaluasi status gizi individu, yang berpotensi memengaruhi kadar hemoglobin dalam darah. Ketidakseimbangan status gizi pada mahasiswa dapat memicu gangguan kadar hemoglobin, seperti anemia. Tujuan penelitian menganalisis hubungan antara IMT dengan kadar hemoglobin pada mahasiswa Jurusan Teknologi Laboratorium Medis, Poltekkes Kemenkes Denpasar. Metode penelitian analytic observational dengan pendekatan cross-sectional, dilaksanakan bulan Oktober 2025–April 2026. Sampel terdiri dari 39 mahasiswa yang dipilih melalui teknik non-probability sampling jenis purposive sampling. Data dikumpulkan melalui pengukuran IMT, pemeriksaan kadar hemoglobin dengan metode cyanmethemoglobin, serta kuesioner pola makan. Analisis data dilakukan dengan uji Spearman Rank. Hasil penelitian menunjukkan responden dengan IMT underweight memiliki kadar hemoglobin rendah sebesar 84,6%. Analisis statistik menunjukkan hubungan signifikan antara IMT dengan kadar hemoglobin (p=0,000) dengan kekuatan korelasi kuat dan arah hubungan positif (r=0,606). Simpulan terdapat hubungan yang signifikan antara indeks massa tubuh dengan kadar hemoglobin pada mahasiswa Jurusan Teknologi Laboratorium Medis, Poltekkes Kemenkes Denpasar. Kata kunci: Indeks Massa Tubuh; Hemoglobin
