The maximum value was 243 mg/dL, the minimum value was 63 mg/dL, the median value was 83 mg/dL, the average value was 94.42 mg/dL, and standard of deviation was 37.85 mg/dL.

Kadar glukosa darah dalam tubuh yang meningkat (hiperglikemia) dapat menjadi gejala penyakit diabetes mellitus. Salah satu faktor yang memengaruhi kadar glukosa darah ialah aktivitas fisik. Aktivitas fisik yang kurang dapat dipengaruhi oleh pekerjaan. Pola hidup sedentary lifestyle identik dengan pekerja kantor dewasa ini. Pekerja kantor tidak memiliki waktu untuk terlibat dalam aktivitas fisik yang cukup. Penelitian ini bertujuan untuk mengetahui gambaran kadar glukosa darah puasa pada pekerja kantor. Jenis penelitian ialah deskriptif dengan desain potong lintang. Pemilihan responden dilakukan dengan metode total sampling. Responden terdiri dari 25 orang laki-laki s dan 27 orang perempuan. Hasil penelitian mendapatkan 45 responden (86,54%) memiliki kadar glukosa darah puasa normal, 5 responden (9,62%) memilki kadar glukosa darah puasa tinggi (hiperglikemia), dan 2 responden (3,84%) memilki kadar glukosa puasa rendah (hipoglikemia). Hasil pengukuran kadar glukosa darah puasa mendapatkan nilai maksimum 243 mg/dL, nilai minimum 63 mg/dL, nilai median 83 mg/dL, nilai rata-rata 94,42 mg/dL dan standar devisiasi 37,85 mg/dL. Simpulan: Sebagian besar pekerja kantor masih memiliki kadar glukosa darah puasa yang normal. Kata kunci: glukosa darah puasa, pekerja kantor
