Although studies in Caucasian populations have reported the beneficial effects of intakes of fruit and vegetables on bone mass, limited data are available in the Asian populations. We examined the association of the intake of fruits and vegetables with bone mineral density (BMD) in a population-based cross-sectional study of 670 postmenopausal Chinese women aged 48-63 years. Habitual dietary intakes were assessed using a food frequency questionnaire. BMD at the whole body, lumbar spine and left hip were measured with dual-energy X-ray absorptiometry. Univariate regression analyses showed that the total intake of fruits and vegetables was significantly associated with greater BMD at the whole body, lumbar spine (L1-L4), total hip, trochanter and intertrochanter. An independently positive association between fruit and vegetable intake and BMD at the whole body (P = 0.005), lumbar spine (P < 0.001) and total hip (P = 0.024) remained even after adjusting for age, years since menopause, body weight and height, dietary energy, protein and Ca, and physical activities. A daily increase of 100 g fruit and vegetable intake was associated with 0.0062 (95 % CI 0.0019, 0.0105) g/cm2, 0.0098 (95 % CI 0.0041, 0.0155) g/cm2 and 0.0060 (95 % CI 0.0011, 0.0109) g/cm2 increases in BMD at the whole body, lumbar spine and total hip, respectively. In conclusion, greater fruit and vegetable intake is independently associated with better BMD among postmenopausal Chinese women.
尽管针对高加索人群的研究报告了水果和蔬菜摄入量对骨量的有益影响，但亚洲人群中的相关数据有限。我们在一项基于人群的横断面研究中，对670名年龄在48至63岁之间的绝经后中国女性进行了调查，以研究水果和蔬菜摄入量与骨矿物质密度（BMD）之间的关联。使用食物频率问卷评估习惯性饮食摄入量。采用双能X线吸收法测量全身、腰椎和左髋部的骨密度。单因素回归分析显示，水果和蔬菜的总摄入量与全身、腰椎（L1-L4）、全髋、大转子和转子间的骨密度显著相关。即使在调整了年龄、绝经年限、体重和身高、饮食能量、蛋白质和钙以及身体活动等因素后，水果和蔬菜摄入量与全身（P = 0.005）、腰椎（P < 0.001）和全髋（P = 0.024）骨密度之间仍存在独立的正相关。每天水果和蔬菜摄入量增加100克，分别与全身、腰椎和全髋骨密度增加0.0062（95%CI 0.0019，0.0105）g/cm²、0.0098（95%CI 0.0041，0.015）g/cm²和0.0060（95%CI 0.0011，0.0109）g/cm²相关。总之，在绝经后中国女性中，水果和蔬菜摄入量增加与更好的骨密度独立相关。
