Description
Being unable to chew, in another words suffering a decrease in masticatory ability, is known to have a close relationship with self-assessed health and depression. This study of the nationwide elderly population in Japan aims to investigate the relation between perceived health and the declining functionalities due to aging, such as decreased auditory perception, visual perception and masticatory ability.<BR>As part of the Nihon University Japanese Longitudinal Study of Aging, by the Nihon University Center for Information Networking, of a panel interview survey of elderly individuals over 65 years old, was conducted in November 1999. 4, 948 answers were obtained through this survey. Multinomial logistic regression analysis was conducted on the survey results, using perceived health as a dependent variable, and age, gender, vision, hearing, chewable groups of food, the CES-D scale and the PGC morale scale as independent variables. Hayashi's quantification method of the third type was used to conduct a preliminary analysis, in order to grasp the inter-variable structure. Data from 3, 069 individuals, who had fully answered items was used for this analysis.<BR>Vision had the strongest relation with perceived health, and had a significant relationship (p<0.05) with the varying perceived health level in every group.Hearing was related in two healthy groups of individuals, those who answered either “excellent” or “good”. Masticatory ability was related in two groups of unhealthy individuals, those who either answered “fair” or “poor.” The CES-D scale and the PGC morale scale was related in every group.No relationship with age was evident in any of the groups, but a gender relationship was evident in the two healthy groups of individuals who answered either “excellent” or “good.”In other words, vision, hearing, and masticatory ability, all of which are known to decrease as a function of age, each exhibited a unique relationship with perceived health. Speaking of mastication in particular, elderly persons should recognize even a slight decrease in masticatory ability as a sign of a potential decrease in their health rating in the near future. Conversely, the results indicated that the maintenance and recovery of masticatory ability in individuals who cannot chew is a basis for improvement from their current fair or poor health status rating.
