PENGARUH PEMBERIAN SUPLEMENTASI SUPEROXIDE DISMUTASE (SOD) TERHADAP KADAR ALBUMIN SERUM PADA LANSIA

Abstract

Background: Levels of serum albumin can be used as a predictor of morbidity and mortality in the elderly. Reduced serum albumin concentration can be caused by oxidative modification due to aging or insufficient protein intake. SOD as an enzymatic antioxidant might prevent oxidative stress so that albumin modification process can be inhibited. SOD supplementation was expected to increase serum albumin levels. Aim: Analyze the effect of SOD supplementation on elderly serum albumin level. Methods: This was a true experimental study with pre and post test control group design.. The study began with 31 elderly, resides in the “Pucang Gading Social Rehabilitation Unit”. They were divided into 2 groups. The control group (15 subjects), received placebo and exercise. The treatment group (16 subjects), received 250 IU SOD/day and exercise. Both treatments were done within 8 weeks, with twice a week exercise. Before and after treatment, levels of serum albumin were measured. Data normality was tested using Saphiro-wilk test. Data was analyzed by Paired-T-test if the distribution is normal, and using Wilcoxon test if the distribution is abnormal. Results: There were increases of serum albumin levels in both groups. Statistical test results showed a significant increase of serum albumin levels in the treatment group of 0.26 ± 0.33 mg/dL with p=0,007 (p<0,05), whereas it was insignificant in the control group of 0.18 ± 0.44 mg/dL with p=0.175 (p>0,05). Conclusion: 250 IU SOD/day supplementation for 8 weeks increase serum albumin levels in the elderly. Keywords: Albumin, elderly, aging, SOD
