Dietary fiber intake and dental health status in urban-marginal, and rural communities in central Mexico.
BACKGROUND
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 chi2 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.
