We compared anthropometric indices in samples of elderly people aged 6
5 years and over living in two French areas. The samples were divided
into four age-groups (65-69, 70-74, 75-79 and over 80 years). We obser
ved interregional differences in women aged 65-69 years and in men age
d 65-74 years. Weight and anthropometric variables related to body fat
percentage and to muscle mass showed a decline with age as already re
ported by others. We established anthropometric percentile values acco
rding to sex in pooled subjects when no integrated difference was foun
d. The 50th percentile of arm circumference, muscle arm circumference
and triceps skinfold was higher, and the 50th percentile of body mass
index was lower than the one reported for the same indices from an eld
erly Welsh population. Our results show that an interregional differen
ce in anthropometric indices exists in the elderly. The differences wh
ich are observed between our results and those reported from a British
population emphasize the importance of establishing local values for
the elderly population.
