概括
每日步行强度,以步行次数 (步行时间超过10分钟) 来衡量,与降低死亡风险有关. 实现更高的每日总步数也显著降低了所有原因死亡的风险.
科学领域:
- 公共卫生 公共卫生
- 流行病学 流行病学
- 身体活动研究 身体活动研究
背景情况:
- 久坐不动的生活方式有助于增加全因死亡率.
- 了解步行强度的具体影响,超出总步数,对于公共卫生指南至关重要.
- 之前的研究主要集中在每天总步数上,不太重视步行持续时间和强度.
研究的目的:
- 为了研究步 (步行10+分钟) 和全因死亡率之间的关联.
- 为了确定是否 bouted 步骤在调整了每日总步骤后,在降低死亡风险方面提供了独立的好处.
- 分析不同级别的总步骤和发作步骤与死亡结果之间的关系.
主要方法:
- 一项队列研究分析了美国国家健康和营养检查调查 (2005-2006) 中2764名参与者的数据.
- 每天总步数和发作步数 (≥600步10分钟发作) 用加速度计数据进行评估.
- 死亡率数据在平均随访时间13.0年内收集,确定了598例死亡.
主要成果:
- 较高的每日总步数 (4000-7999,8000-11999,≥12000) 与所有原因死亡率的危险比率显著降低相关,而<4000步/天.
- 服用每天≥600次发作步骤与所有原因死亡率的危险比率降低有关 (0.56 [0.40, 0.78]),与每天零次发作步骤相比,经过对步骤总数进行调整后.
- 即使是中等水平的发作步骤 (86-599步/天) 也显示出降低死亡率的趋势,尽管在统计学上并不显著 (0.83 [0.59, 1.16]).
结论:
- 每天总步数和每天步数都显示出与降低全因死亡率的有益关联.
- 除了足够的每日总步数外,促进长达10分钟或更长时间的步行可以进一步增强健康益处.
- 未来的研究应该旨在证实这些发现,并为身体活动的公共卫生战略提供信息.

Actuarial Approach
276
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.
