Description

<p>　Sarcopenia has attracted attention as a condition necessitating care in the elderly. Sarcopenia in elderly people is attributable to undernutrition, which is related to changes in dietary intake and the food items consumed. We investigated factors that may contribute to changes in the food items consumed by the elderly in an effort to establish measures to prevent sarcopenia.</p><p>　We assessed the health care awareness and physical/oral functions of 155 community-dwelling elderly people in Kyoto （38 men and 117 women；mean age, 74.2±5.4）. We also assessed nutrient intakes using the brief-type self-administered diet history questionnaire（BDHQ）and examined intake frequency changes during the prior 5 years for 45 food items, among those listed in the BDHQ, other than seasonings and beverages.</p><p>　The covariance structure analysis conducted to examine the interactions among the factors contributing to a decreased intake frequency revealed that the higher the health care awareness, the greater the number of food items showing a decreased intake frequency, though chewing ability had no impact. In addition, respondents reporting a greater number of food items with decreased intake frequency were more likely to suffer from sarcopenia.</p><p>　Our study demonstrated that elderly people may maintain their nutritional status while changing the food items consumed in order to preserve their health, as reflected by their decreased oral function. However, as to health care awareness, a false sense of how to meet needs and maintain overall health may lead elderly people to consciously reduce the nutrient content of their diets, thereby posing a risk of sarcopenia.</p>
