UNLABELLED
The aim of this study was to analyze the association between Physical Activity (PA) and forearm bone mineral density (BMD) in healthy postmenopausal women. During 1984-1986, a population-based health survey (HUNT-1) was conducted in Nord-Trøndelag county, Norway. The second follow-up survey (HUNT-2) was conducted during 1995-1997. The subjects consist of all healthy postmenopausal women (N = 2,924). Higher intensity of recreational PA in HUNT-1 was associated with higher BMD ultradistally (slope = +0.0084, p = 0.0009). The summary score of duration, frequency and intensity of recreational PA in HUNT-1 was associated with lower risk of being below the 20th percentile ultradistally (OR = 0.90, p = 0.01, after adjustment for covariates). The trends for mean distal and ultradistal BMD and percent low BMD lacked statistical significance when we used the PA score that combined the recreational and occupational PA in HUNT-1 and HUNT-2.
CONCLUSION
Higher intensity of prior recreational PA (HUNT-1) was associated with a protective effect on BMD measured in the forearm (HUNT- 2).
未标注
本研究旨在分析健康绝经后女性的身体活动（PA）与前臂骨矿物质密度（BMD）之间的关联。1984年至1986年期间，在挪威北特伦德拉格郡进行了一项基于人群的健康调查（HUNT-1）。第二次随访调查（HUNT-2）于1995年至1997年期间进行。研究对象包括所有健康的绝经后女性（N = 2,924）。HUNT-1中较高强度的娱乐性身体活动与更远端的较高骨密度相关（斜率 = +0.0084，p = 0.0009）。HUNT-1中娱乐性身体活动的持续时间、频率和强度的综合得分与更远端低于第20百分位数的风险较低相关（调整协变量后，OR = 0.90，p = 0.01）。当我们使用结合了HUNT-1和HUNT-2中的娱乐性和职业性身体活动的身体活动得分时，平均远端和超远端骨密度以及低骨密度百分比的趋势缺乏统计学意义。
结论
先前较高强度的娱乐性身体活动（HUNT-1）与前臂测量的骨密度具有保护作用相关（HUNT-2）。
