 note = {Objectives: Protein-energy malnutrition (PEM) among elderly is a risky　state, which leads to limited activities of daily life and a bedridden state. Oral health status in elderly can be one of the indicators to occur PEM. The purpose of this study was to assess the correlation changes of posterior occlusal support status and incidence of PEM over 5 years in the Japanese community-dwelling elderly.
 Methods: Two hundred and seventy-two subjects aged 75-year-old in 2003 were followed up in 2008. Posterior occlusal support without denture in 2003 and 2008 were categorized into one of three groups based on the number of occlusal support zone (OSZ). According to the concept of Eichner’s Index and changes of them over 5 years, five groups for the main exposure variables were defined as 1) Complete: remain four OSZ, 2) Moderate: remain one to three OSZ, 3) Lost support: remain no OSZ, 4) Early change: change from four to one to three OSZ and 5) Late change: change from one to three to no OSZ. For the outcome variables, rates of changes in protein intake, total energy intake and BMI over 5 years were calculated and divided into two groups. Additionally, nutrition status for malnutrition criteria were defined: A) IPE; rates of changes in protein intake and total energy intake were less than or equal median and B) IPEB; rates of changes in three items were less than or equal median.
 Results: Male subjects whose the number of posterior OSZ decreased from four to one to three over 5 years had significantly higher risk in IPE and IPEB compared with those in another groups (odds ratio: 4.0 for IPE and 4.3 for IPEB).
 Conclusion: Male elderly who lost the number of posterior occlusal support zone declined protein intake and increased risk for PEM., 学位の種類: 博士（歯学）. 報告番号: 甲第4564号. 学位記番号: 新大院博（歯）甲第413号. 学位授与年月日: 平成31年3月25日, Dentistry. 2019, 9(2), 534, 新大院博（歯）甲第413号},
