The aim of this study was to analyze the relationship between oolong tea drinking and bone mineral density in postmenopausal Han Chinese women, while living and diet habits, fertility, disease elements and other baseline conditions were controlled. One group included 124 cases who routinely drank oolong tea, and the other included 556 who did not drink tea. Data were collected on participant age, lifestyle habits, fertility condition, disease elements, and lumbar, and hip bone densities. It was found that the bone densities of the greater trochanteric bone in tea drinkers were higher (0.793 ± 0.119 kg/cm(2)) than that in non-tea drinkers (0.759 ± 0.116 kg/cm(2), F = 6.248, p = 0.013). Similarly, the bone density of Ward's triangular bone in tea drinkers was higher (0.668 ± 0.133 kg/cm(2)) than that in non-tea drinkers (0.637 ± 0.135 kg/cm(2), F = 6.152, p = 0.013). Oolong tea drinking could help prevent bone loss in postmenopausal Chinese women.
