Stature, total arm length, and subischial length were studied in a cro
ss-sectional sample of 387 working (career women) and 460 nonworking w
omen (housewives), 20-75 years of age, from one endogamous group, the
Khatris. Statural decrease due to aging was separated from secular eff
ects by using total arm length, which was least affected by aging. The
rate of loss in stature due to aging was 0.142 cm/year in the working
women and 0.140 cm/year in the nonworking women. Both estimates are s
ignificantly different from zero. After adjusting stature for estimate
d aging effects, the resulting secular estimates were 0.004 cm/year in
working women and 0.01 cm/year for nonworking women, both of which do
not significantly differ from zero. (C) 1995 Wiley-Liss, Inc.
