Daftar Isi:
- The aim of this cross-sectional study was to assess serum zinc levels in patients with type 2 diabetes mellitus (DM) and its association with zinc, animal protein, phytate, and dietary fiber intakes. Sixty-eight patients aged 40-64 years have provided consent, while 58 subjects (85.29%) have completed the study. Data collection were conducted from interviews, anthropometric measurements, and dietary assessments. Serum zinc level, fasting and post-prandial blood glucose were assessed. Median figure of zinc intake obtained from food record was 5.95 (4.92 – 7.13 mg) for males and 5.16 mg (4.54 – 6.03 mg) for females, therefore only 3.45% subjects met Indonesian Recommended Dietary Allowance (RDA). 81.03% subjects had lower proportion of intake of protein from animal source than those recommended. Despite sufficient dietary fiber, 93.10% subjects had low zinc absorption estimation level. Majority of the subjects (77.6%) was categorized as poor-controlled glucose level. Low serum zinc level was found in 12.07% subjects. There was a significant correlation between serum zinc level and the percentage of animal protein intake (r=0.375, p=0.002). No significant associations were found between serum zinc level and zinc, animal protein, dietary fiber intakes, and estimation of zinc absorption levels.Keywords: Type 2 diabetes mellitus, zinc, protein, phytate, dietary fiber, blood glucose, serum zinc
