目的进一步确定骨峰形成的年龄和影响峰值骨量、骨密度的因素，为预防老年骨质疏松寻找有效途径。方法对781例15～50岁健康人进行骨密度测定和生活因子调查，对生活因子与骨密度的关系进行多元回归分析，确定危险因子和有利因子。结果体重每增加10kg，男性不同部位骨密度值将相应升高0．028～0．056g／cm2，女性升高0．050～0．086g／cm2；青少年时期男性运动量每增加1个等级，骨密度在不同部位升高0．034～0．078g／cm2，女性腰椎和全身约升高0．035g／cm2；15～24岁的男性腰椎骨密度与饮酒总量呈负相关；25～50岁者全身和腰椎骨密度与抽烟总量呈负相关；女性腰椎骨密度与初潮呈负相关；女性平均母乳喂养时间与腰椎骨密度呈正相关。结论加强青少年时期体育锻练，能有效提高峰值骨量，保持适当体重和减少烟、酒摄入量有利于预防老年骨质疏松。
Objective To further determine the age of bone formation and the factors that affect peak bone mass and bone density, and find effective ways to prevent osteoporosis in the elderly. Methods A total of 781 healthy people aged 15-50 years were surveyed for bone mineral density and life factors. Multiple regression analysis was performed to determine the risk factors and favorable factors for the relationship between life factors and bone mineral density. Results When the body weight increased by 10kg, the bone mineral density in different parts of the male would increase by 0.028-0.056g/cm2, and that of the female rose by 0.050-0.086g/cm2. For every one increase in male fitness during adolescence, the bone density increased by 1 The density increased 0.034-0.078g/cm2 in different parts, and the female lumbar vertebrae and whole body increased about 0.035g/cm2; the bone density of lumbar vertebrae was negatively correlated with the total alcohol consumption in men aged 15-24 years; 25-50 years old There was a negative correlation between total body and lumbar spine bone density and total smoking; female lumbar spine bone density was negatively correlated with menarche; female breastfeeding time was positively correlated with lumbar spine bone density. Conclusion The strengthening of physical exercise during adolescence can effectively increase the peak bone mass, maintain proper body weight and reduce the intake of tobacco and alcohol, which is beneficial to the prevention of osteoporosis in the elderly.
