Abstract:
Introduction. Oral health status in older people is frequently
poor which can contribute to inadequate dietary patterns and
nutrition status. Objective. To investigate whether an
association between the number of teeth present and dietary
fiber intake exists in elderly people living independently,
across different geographic and socioeconomic locations.
Methods. A cross-sectional household survey was undertaken in
three Mexican communities (urban, marginal urban, and rural),
incorporating geographic and socio-demographic information and a
24-hour diet recall. Dental status (teeth present, coronal and
root caries, and periodontal status) was determined by clinical
examination. Data were analyzed using ANOVA, Pearson's X2 and
Tukey's range tests. Results. 407 persons 60 years old and over
participated in the study. Subjects in the rural community had
better dental/periodontal status and more teeth present than
urban and marginal-urban participants. Intake of fiber was 8.4
g/day for the urban, 7.6 g/day for the marginal-urban, and 13.5
g/day for the rural community. While gender had no detectable
effect, the location of residence and the number of teeth
present were associated with mean fiber intake; having more than
21 teeth and/or living in a rural location were associated with
increased mean fiber intake.
Key words:
Dental health, Mexico, dietary fiber, nutrition, elderly, teeth.

VALIDITY
OF MEASURING KNEE-HEIGHT AS AN ESTIMATE OF HEIGHT
IN DISEASED FRENCH ELDERLY PERSONS

Abstract:
Body mass index is a tool to screen undernourished persons.
Cut-off values of 22 or 24 kg/m2 are used for
elderly persons. However, standing height cannot be measured
in every elderly person. Knee-height has been proposed to,
estimate standing height, with equations derived from
North-American people. The present study analyses the
validity of these equations. Standing height and knee-height
were measured in 126 elderly persons hospitalized in 6
French geriatrics wards. Consequences of using one of the
either height was evaluated on body mass index, body surface
area, and total body water as estimated from bioelectrical
impedance measurements. Standing height and height derived
from knee-height differed significantly by 0.9 cm (P=0.05).
This has very limited consequences on the calculation of BMI
(0.5 kg/m2), body surface area (0.04 m2) and on
total body water (0.2 litres). A regression model was
derived from covariates and found the same features as that
in the model of Chumlea and Guo. In conclusion, knee-height
can be used with sufficient accuracy as a surrogate for
standing height in diseased French elderly persons.
