HUBUNGAN ANTARA ASUPAN PROTEIN, ZAT BESI, VITAMIN C, DAN INHIBITOR ABSORPSI ZAT BESI DENGAN STATUS ANEMIA PADA LANJUT USIA DI PAGUYUBAN �WIRA WREDHA� WIROGUNAN, YOGYAKARTA

Background : The prevalence of anemia in older people based on data from NHANES III by 11,0% of men and 10,2% of women suffered from anemia. Anemia is a risk factor that can be increase morbidity and mortality and decrease quality of life in older people. One of the anemia�s cause in older people is an undernutrition (nutritional anemia) such as iron deficiency anemia. This can occur due to inadequate intake of protein, iron, and vitamin C, with inhibitory factors of iron absorption such as tannin, phytate, and oxalate acid. Objective : To determine the relationship between intake of protein, iron, vitamin C, and iron absorption inhibitors with anemia status in older people at Paguyuban �Wira Wredha� Wirogunan, Yogyakarta. Method : The study used observational study with cross sectional design. Subjects for the study were 99 older people at Paguyuban �Wira Wredha� Wirogunan, Yogyakarta who complied for inclusion and exclusion criteria. Data collected include protein intake, iron intake, vitamin C intake, iron absorption inhibitors intake, body weight, and hemoglobin concentration. Data related to intake of protein, iron, vitamin C, and iron absorption inhibitors obtained by interview using SQFFQ. Body weight measured using weight scales. Hemoglobin concentration measured using hemocue method. The statistical test used to analyze the relationship is a Chi Square test or Fisher�s exact test, whereas statistical test used to look the biggest contribution is a logistic regression. Results : The prevalence of anemia in older people was 18,2%. There was significant relationship between intake of protein with anemia status in older people (p=0,005). There was significant relationship between intake of iron with anemia status in older people (p=0,007). There was no significant relationship between intake of vitamin C with anemia status in older people (p=0,636). There was no significant relationship between intake of iron absorption inhibitors (tannin, phytate, oxalate acid) with anemia status in older people (p=0,18
