Methods The study population consisted of 2884 healthy people aged 10-92 years (1481 males, 1403 females). BMD of middle phalanges of the index, middle and ring fingers (MP2, MP3, MP4)in the non-dominant hand were measured by RA (Compumed, Inc, U. S. A. , OsteoGram-2000) .They were divided into 10-year groups of each for analysis. Results The peak bone mass (PBM) layin 20-29 year group for males and of age whereas thatin 20 - 39 year group for females. The BMD in males decreased with increasing age after 30 years females decreased with increasing age after 40 years of age. The average at age menopause in Beijing women was 50 years. The amual bone loss rate was 1.35% during 20 years after menopause. The results correlated favorably with BMD data of 40000 Chinese investigated in the late 80's using forearm (radius and ulna) single-photon absorptiometry(Liu,et al). Conclusion The regularities of PBM and bone loss measured by RA in Beijing are the same as those by of DXA or SPA in other parts of China.Read More
