Background: There are presently no published data on age-related changes in body composition in French individuals older than 65 or 80 years. This paper presents a cross-sectional study of 7518 community-residing French women older than 75 years. Methods: We examined age differences changes in body composition and anthropometry between age groups (76-80, 81-85, and 86-95 years of age). Whole body composition was estimated using a dual energy X-ray absorptiometry (DXA) scanner. Measurements of appendicular skeletal muscle (ASM) mass and sarcopenia were performed for a subsample of 1321 women. Results: Significant age differences exist in total fat mass and total bone mineral content in elderly women between 76 and 95 years of age. There was also a significant decreased in fat free soft tissue mass from 76 to 85. The decline in fat free mass may be reduced over 85 years of age. The prevalence of low muscle mass, or sarcopenia, increased with age from 8.9 in 76-80 to 10.9% in 86-95 age group, but the difference was not statistically significant. Conclusions: Interventional programs developed to prevent or reduce sarcopenia would have a better influence on population under 85 years, i.e. when the decline in ASM mass is the most severe. Others longitudinal studies could be performed to confirm our results. (C) 2003 Published by Elsevier Science Ireland Ltd.
