在2026年于北京举行的健康骨骼科普传播大会上，多位医学专家指出，单纯补钙不足以维持骨骼健康，公众应重视骨骼与肌肉的协同管理。1针对我国公众维生素D缺乏比例高达61.3%的现状，中国营养学会推荐成人每日摄入400至600单位维生素D，一般不超过2000单位的可耐受最高摄入量。1对于极高骨折风险人群，界定标准包括两年内低能量外力导致主要部位骨折、五年内多次脆性骨折、抗骨质疏松治疗期间再次骨折、骨密度极低、长期使用中等剂量糖皮质激素以及过去一年有两次及以上跌倒等情形。1
为帮助公众及早发现肌少症风险，专家介绍了三个居家自测动作及临界值标准。1首先，女性握力小于18公斤、男性小于28公斤时应警惕风险；其次，女性小腿围小于33厘米、男性小于34厘米提示可能存在肌肉减少；最后，连续起立坐下5次耗时超过12秒则表明肌肉功能可能下降。1
At the 2026 Healthy Bones Science Communication Conference in Beijing, medical experts emphasized that bones and muscles must be managed together, noting that calcium supplementation alone is insufficient for maintaining skeletal health 1. The conference focused on raising public awareness of bone health and introducing methods for sarcopenia screening 1.
Experts outlined three home-based self-tests to assess sarcopenia risk: grip strength measurement, calf circumference assessment, and a sit-to-stand timing test 1. Warning signs include grip strength below 18 kg for women or 28 kg for men, and a calf circumference smaller than 33 cm for women or 34 cm for men, which may indicate muscle loss 1. Additionally, taking more than 12 seconds to complete five consecutive sit-to-stand repetitions suggests declining muscle function 1.
The conference also highlighted that Vitamin D deficiency affects 61.3% of the general population in China 1. The Chinese Nutrition Society recommends an adult daily intake of 400–600 units of Vitamin D, with a tolerable upper limit generally not exceeding 2,000 units 1.
Definitions were provided for populations at extremely high fracture risk. Criteria include sustaining a major fracture from low-energy trauma within two years, experiencing multiple brittle fractures within five years, suffering repeated fractures while undergoing osteoporosis treatment, having very low bone mineral density, long-term use of medium-dose glucocorticoids, or having fallen two or more times in the past year 1.
