Few studies on older populations consider several energy balance-related behaviors together. This cross-sectional study compared subjectively and objectively measured physical activity (PA) and sedentary behavior (SB) patterns between older adults with and without a healthy diet. We recruited 127 community-dwelling older Taiwanese adults (69.9 ± 5.0 years); data were collected during April and September 2018. Objectively measured total PA, moderate-to-vigorous PA, light PA, step count, total sedentary time, duration of sedentary bouts, number of sedentary bouts, and number of sedentary breaks were assessed using activity monitors. Subjectively measured PA and SB were measured using the International Physical Activity Questionnaire and Sedentary Behavior Questionnaire for Older Adults. Chi-square tests and independent sample t-tests were performed. For subjective measures, older adults without a healthy diet spent significantly less total leisure time on PA and more leisure sitting time than those with a healthy diet. For objective measures, older adults without a healthy diet spent less time on light PA and had a higher total sedentary time, duration of sedentary bouts, times of sedentary bouts, and times of sedentary breaks than those with a healthy diet. Regardless of the use of objective or subjective measurements, older adults without a healthy diet engaged in a more inactive and sedentary lifestyle. These findings have implications for health promotion practitioners in designing tailored interventions.
很少有研究同时考虑几种与能量平衡相关的行为。本横断面研究比较了饮食健康和不健康的老年人之间主观和客观测量的体力活动（PA）和久坐行为（SB）模式。我们招募了 127 名居住在社区的台湾老年成年人（69.9 ± 5.0 岁）；数据于 2018 年 4 月和 9 月收集。使用活动监测器评估客观测量的总 PA、中高强度 PA、低强度 PA、步数、总久坐时间、久坐时间持续时间、久坐次数和久坐休息次数。使用国际体力活动问卷和老年人久坐行为问卷测量主观测量的 PA 和 SB。进行了卡方检验和独立样本 t 检验。对于主观测量，饮食不健康的老年人在休闲时间内进行的总 PA 明显较少，而坐着的休闲时间明显较多。对于客观测量，饮食不健康的老年人的轻 PA 时间较少，总久坐时间、久坐时间持续时间、久坐次数和久坐休息次数都较高。无论使用客观还是主观测量，饮食不健康的老年人的生活方式都更不活跃和久坐。这些发现对健康促进从业者设计量身定制的干预措施具有重要意义。
