Four hundred subjectstaken using purposive sampling, sample aged 55 years old and above, nutrition status was taken directly (anthropometric)BB/TB2 and mastication capability taken with custom questioner along with scoring value. The result showed that elderlyBuginese had 64.9% with poor nutrition status caused by poor mastication capability, mastication capability and nutritionstatus in elderly Buginese had significant relation (p=0.04), while elderly Mandarnese had 39.8% with poor nutritionstatus caused by poor mastication capability, but statistically, the relation between mastication capability with nutritionstatus in elderly Mandarnese was not significant (p=0.076). As conclusion there was significant relationship betweenmastication capability and nutrition status in Buginese and Mandarnese, and mastication capability and nutrition status ofMandarnese were better than Buginese.
