| Summary: | 碩士 === 嘉南藥理科技大學 === 營養與保健科技研究所 === 96 === The purpose of this study was to assess comprehensively the nutrition status of elderly individuals in homebound and to compare it with institutionalized elderly in Chiayi area. A total of 231 elderly persons (homebound 84, institutionalized 147), 65 years old and older were included in the study, their nutritional status was assessed by anthropometric measurements, mini nutritional assessment (MNA) and dietary food intake for a 3-day period, dietary intake was analyzed by food composition software. Energy, macro and micronutrient intakes were compared with dietary reference intakes (DRIs) as appropriate. Total and male elderly in the homebound had significantly higher height, weight and calf circumference (CC) values than those institutionalized elderly, and the female elderly in homebound also had higher CC value than with institutionalized female elderly (p<0.05). The prevalence of underweight in institutionalized elderly and both genders was greater than those in homebound. On the other hand, the prevalence of obesity of total and female elderly in homebound was higher than those institutionalized elderly. Malnutrition proportion were higher in institutionalized elderly and both genders than those homebound elderly. Mean intakes of carbohydrate and micronutrient vitamin E, vitamin B6, calcium and magnesium were lower than DRIs for whole participants. Farther, inadequate intake with energy, vitamin B2, phosphorous and iron was noted in institutionalized elderly. Total homebound elderly had higher energy, macro and micro nutrient intakes than with institutionalized elderly, except for vitamin E and vitamin B1. Furthermore, excess sodium consumption was noted in both groups, the institutionalized elderly take more sodium than in homebound elderly. Higher energy, macronutrient and mineral intakes were observed in homebound male elderly than in institutionalized male elderly except for vitamin A, vitamin E, vitamin B1 or vitamin C. There were no significant differences or lower energy and nutrient intakes for females between both groups, except for fiber, vitamin B6 , vitamin C and mineral which were significantly higher in homebound female elderly. The homebound elderly and both genders had higher ADL and IADL values and lower GDS value than those institutionalized elderly. In summary, the results of the present study showed the proportion of malnutrition or at risk malnutrition was 4.7-17.7% or 35.7-51.7 % detected by the MNA in Chiayi area, it was also found that elder people living in institutionalized have more risk for malnutrition, these individuals are more likely to have a decrease energy, carbohydrate and micronutrient intakes. It is recommended that to increased energy, cereal and cereal products, milk and milk products intakes for both homebound and institutionalized elderly in Chiayi area.
