BACKGROUND
Interventions other than medications in the management of osteoporosis are often overlooked. The purpose of this study was to investigate the association of physical activity and calcium intake with bone parameters.
METHODS
We measured the heel T-score and stiffness index (SI) in 1890 pre- and postmenopausal women by quantitative ultrasound (QUS) and assessed physical activity and dietary calcium intake by questionnaire. Participants were divided according to their weekly physical activity (sedentary, moderately active, systematically active) and daily calcium consumption (greater than or less than 800 mg/day).
RESULTS
SI values were significantly different among premenopausal groups (p = 0.016) and between sedentary and systematically active postmenopausal women (p = 0.039). QUS T-scores in systematically active premenopausal women with daily calcium intake > 800 mg/day were significantly higher than those in all other activity groups (p < 0.05) independent of calcium consumption.
CONCLUSIONS
Systematic physical activity and adequate dietary calcium intake are indicated for women as a means to maximize bone status benefits.
背景
在骨质疏松症的治疗中，除了药物治疗之外，其他干预措施往往被忽视。本研究旨在探讨体力活动和钙摄入量与骨参数的关系。
方法
我们通过定量超声（QUS）测量了 1890 名绝经前和绝经后妇女的足跟 T 评分和硬度指数（SI），并通过问卷调查评估了体力活动和膳食钙摄入量。参与者根据每周的体力活动（久坐、适度活跃、系统活跃）和每日钙摄入量（大于或小于 800 毫克/天）进行分组。
结果
绝经前组的 SI 值存在显著差异（p = 0.016），且久坐和系统活跃的绝经后妇女之间也存在显著差异（p = 0.039）。在每日钙摄入量大于 800 毫克的系统活跃的绝经前妇女中，QUS T 评分显著高于其他所有活动组（p < 0.05），而与钙摄入量无关。
结论
系统的体力活动和充足的膳食钙摄入对女性来说是一种最大限度地提高骨骼健康益处的方法。
