Abstract

Adiponektin adalah suatu adipositokin yang dihasilkan dari jaringan lemak. Adiponektin mempunyai peranan penting dalam regulasi dari metabolisme glukosa dan resistensi insulin. Penelitian klinis menunjukkan bahwa kadar adiponektin lebih rendah pada subyek obes, diabetes dan penderita penyakit arteri koroner. Studi ini meneliti perbedaan kadar adiponektin pada subyek obes dengan resistensi inulin. Tujuan penelitian ini adalah untuk mengetahui perbedaan kadar adiponektin antara subyek obes dengan resistensi insulin dibandingkan subyek obes normal. Kadar adiponektin plasma diperiksa pada 72 subyek dengan indeks massa tubuh (IMT) >25kg/m2. Resisitensi insulin diukur dengan menggunakan formula homeostasis model assessment insulin resistance (HOMA IR) dari kadar insulin dan glukosa puasa. Kadar adiponektin plasma diukur dengan teknik ELISA. Diperiksa kadar glukosa darah, insulin dan profil lipid puasa. Hasilnya menunjukkan bahwa usia rerata adalah 46.39±6.45 tahun dengan IMT 29.83±3.57 kg/m2 dan kadar adiponektin 4.2±1.79 ?g/ml. Kadar adiponektin lebih rendah bermakna pada subyek obes. Kadar adiponektin tidak berbeda bermakna antara subyek obes dengan dan tanpa resistensi insulin (P=0.41). Tidak ada perbedaan proporsi seks diantara subyek obes dengan dan tanpa resistensi insulin (p=0.374). Analisis regresi logistik menunjukkan perbedaan dalam IMT, lingkar pinggang dan kadar glukosa 2 jam setelah makan pada subyek dengan resistensi insulin. Dari penelitian ini tidak didapatkan adanya perbedaan kadar adiponektin pada subyek obes yang mengalami resistensi insulin dan yang tidak mengalami resistensi insulin.
