Asupan Vitamin C dan E Tidak Mempengaruhi Kadar Gula Darah Puasa Pasien DM Tipe 2

Abstrak Prevalensi diabetes melitus di Jawa Timur menempati urutan ke-5 teratas Indonesia. Diabetes melitus terjadi akibat resistensi insulin sehingga kadar gula darah tinggi. Kontrol glukosa darah pada pasien diabetes mellitus dapat dipengaruhi oleh asupan vitamin C dan E dengan menghambat stres oksidatif. Banyak penelitian melihat efek pemberian suplementasi kedua vitamin tersebut namun penelitian mengenai asupan makan harian sumber vitamin C dan vitamin E terhadap kadar glukosa darah puasa di Indonesia belum banyak dilakukan. Tujuan penelitian ini adalah mengetahui hubungan asupan vitamin C dan E terhadap kadar gula darah puasa pasien rawat jalan diabetes melitus tipe 2 di Puskesmas Dinoyo dan Janti Kota Malang. Penelitian ini merupakan penelitian cross sectional dengan jumlah responden 31 orang yang diambil secara purposive sampling. Data asupan vitamin C dan E selama 3 bulan terakhir dicatat menggunakan form SQ-FFQ. Nilai median asupan vitamin C dan vitamin E seluruh responden berturut-turut adalah 95,1 mg dan 5,3 mg. Median kadar glukosa darah puasa seluruh responden adalah 191 mg/dL. Uji analisa hubungan vitamin C dan E dengan kadar gula darah menggunakan uji Pearson (CI 95%) menunjukkan nilai hubungan asupan vitamin C dan E terhadap kadar gula darah berturut-turut p = 0.697 dan p = 0.215. Disimpulkan bahwa tidak ada hubungan antara asupan vitamin C dan vitamin E terhadap kadar gula darah pasien rawat jalan DM tipe 2 di Puskesmas Dinoyo dan Janti Kota Malang.

Blood glucose control in diabetes mellitus patients can be affected by vitamin C and E intake through inhibiting oxidative stress. Many research have studied the effects of both vitamins supplementation but research on daily intake of vitamin C and vitamin E sources on fasting blood glucose level in Indonesia have not been widely conducted. This research aims to determine the effect of vitamin C and E intake on fasting blood sugar level of diabetes mellitus type 2 patients in Dinoyo and Janti Health Center Malang. This research was cross sectional research with 31 respondents taken by purposive sampling. Data on vitamin C and E intake during the last 3 months were documented using SQ-FFQ form. The mean values of vitamin C and vitamin E intake of all respondents were 95.1 mg and 5.3 mg, respectively. The mean fasting blood glucose level of all respondents was 191 mg/dL. Test analysis of vitamin C and E relationship with blood sugar level using Pearson test (95% CI) showed the value of vitamin C and E intake relation to blood sugar level were p = 0.697 and p = 0.215, respectively.
