In Hong Kong physical activity and calcium intake of 400 Chinese men and women with hip fractures were compared with those of 800 controls. Daily walking outdoors, upstairs, uphill, or with a load protected against fracture. This was independent of cigarette smoking and alcohol consumption. Higher levels of reported activity in middle life were also protective. Average calcium intake was around one quarter that in Britain because of the low consumption of dairy products. Differences in calcium intake depended mainly on consumption of green vegetables and small fish. High intake protected against hip fracture. These findings point to the importance of maintaining daily physical activity and calcium intake in urbanised Chinese populations.
在香港，对400名髋部骨折的中国男女的身体活动和钙摄入量与800名对照组进行了比较。每日户外行走、爬楼梯、爬坡或负重可预防骨折。这与吸烟和饮酒无关。中年时期较高的活动水平也具有保护作用。由于乳制品消费量低，平均钙摄入量约为英国的四分之一。钙摄入量的差异主要取决于绿色蔬菜和小鱼的消费量。高钙摄入量可预防髋部骨折。这些发现表明，在城市化的中国人群中保持日常身体活动和钙摄入量非常重要。
