峰值骨量(PBM)即人一生中骨成熟末期达到的最大骨量,是人一生中骨最坚硬、骨矿含量最高的时期。年轻成人PBM值的高低对老年骨量至关重要,是决定老年期是否发展为骨质疏松症(OP)的重要因素。PBM的形成严格受遗传的控制和环境因素的影响。不同个体的PBM相差较大,PBM差异的60%～80%是由遗传因素决定,其余20%～40%则是由环境因素如运动、钙摄入、生活方式、身体疾病状态等决定,年轻成人时获得的最大PBM是预防老年OP性骨折的根本性重要措施。
The peak bone mass (PBM) is the maximum amount of bone that is reached by the end of bone maturity in a person’s life, and is the period in which the bone is the hardest in the human life with the highest bone mineral content. The level of PBM in young adults is crucial for the elderly bone mass and is an important determinant of whether or not elderly people develop osteoporosis (OP). The formation of PBM is strictly influenced by genetic control and environmental factors. PBM difference between different individuals larger, PBM differences of 60% to 80% is determined by genetic factors, the remaining 20% to 40% is determined by environmental factors such as exercise, calcium intake, lifestyle, physical condition, etc., young The largest PBM obtained in adults is a fundamental and important measure to prevent OP fractures in the elderly.
