摘要

背景：尽管人们对体育活动（PA）和过度久坐有着广泛的兴趣，但目前尚不清楚老年人的PA和久坐行为（SB）的实际模式是什么，以及它们与肥胖的关系。目的：本研究的目的是调查老年女性PA和SB的总量和定义发作次数与肥胖指标之间的横断面相关性。方法：采用313名社区妇女的资料。所有女性佩戴加速计一周，并接受身体成分分析。我们使用了三个肥胖指标：脂肪质量百分比（FM%）、内脏脂肪面积（VFA）、脂肪质量指数（FMI）；以及无脂肪质量指数指标（FFMI）。在多元线性回归分析中，我们调整了以下混杂因素的模型：年龄、穿着时间、社会人口统计信息、吸烟和健康状况。结果：FM%、VFA、FMI和FFMI的平均值分别为36.1%、125.9cm、10kg·m-2和17kg·m-2。每周每增加150分钟的MVPA（无论比赛时间长短），FM%下降3.0%，VFA下降12cm2，FMI下降1.5kg·m-2。关于与发作频率的强相关性，每周15次持续≥10分钟的MVPA（以达到每周至少150分钟MVPA的目标）将使FM%下降4.8%，VFA下降24.15cm2，FMI下降2.55kg·m-2。FM%、VFA和FMI与久坐≥20分钟的持续时间和频率呈正相关（β范围为0.05-0.42）。结论：老年妇女的脂肪指标与PA和SB之间存在显著相关性。与持续时间≥10分钟的发作MVPA相比，发作频率的有益关联要大得多。这项研究使用SB和PA在总累积时间和不同发作次数方面的结果可能有助于为居住在社区的老年妇女设计干预措施。

Associations between adiposity and physical activity and sedentary behaviour patterns in older women

Background: Despite broad interest in physical activity (PA) and excessive sitting, it remains unclear what the actual patterns of PA and sedentary behaviour (SB) in older adults are and how they are associated with adiposity. Objective: The aim of this study was to investigate the cross-sectional associations between the total amount and defined bouts of PA and SB with adiposity indicators in older women. Methods: Data on 313 community-dwelling women was used. All women wore an accelerometer for one week and undergone the body composition analysis. We used three adiposity indicators: fat mass percentage (FM%), visceral fat area (VFA), fat mass index (FMI); and the fat-free mass index indicator (FFMI). In multiple linear regression analyses, we adjusted the models for the following confounders: age, wear time, socio-demographic information, smoking, and health status. Results: The mean values of FM%, VFA, FMI, and FFMI were 36.1%, 125.9 cm, 10 kg ⋅ m-2 and 17 kg ⋅ m-2, respectively. Each additional 150 minutes of MVPA per week (regardless of bout length) was associated with a decrease of 3.0% in FM%, 12 cm2 in VFA, and 1.5 kg ⋅ m-2 in FMI. Regarding strong association with bout frequency, doing MVPA lasting ≥ 10 minutes 15 times/week (to meet the target of at least 150 minutes of MVPA/week) would be associated with a decrease of 4.8% in FM%, 24.15 cm2 in VFA, and 2.55 kg ⋅ m-2 in FMI. Significant positive associations for FM%, VFA, and FMI were found with the duration and frequency of sedentary bouts lasting ≥ 20 minutes (β ranging from 0.05-0.42). Conclusions: Significant associations between fat indicators and both PA and SB were found in elderly women. The beneficial associations were much larger for frequency than for duration of bouted MVPA lasting ≥ 10 minutes. The results from this study using SB and PA in terms of total accumulated time and different bouts could be useful for designing interventions for community-dwelling older women.
