Health-related quality of life (HRQoL) reflects an individual's perception of their physical and mental health over time. Despite numerous studies linking physical activity to improved HRQoL, most rely on self-reported data, limiting the accuracy and generalizability of findings. This study leverages objective accelerometer data to explore the association between physical activity and HRQoL in Korean adults.
The objective of this study is to analyze the relationship between objectively measured physical activity using accelerometers and HRQoL among Korean adults, aiming to inform targeted interventions for enhancing HRQoL through physical activity.
This observational study included 1298 participants aged 19-64 years from the Korea National Health and Nutrition Examination Survey (KNHANES) VI, who wore an accelerometer for 7 consecutive days. HRQoL was assessed using the EQ-5D questionnaire, and physical activity was quantified as moderate-to-vigorous physical activity accelerometer-total (MVPA-AT) and accelerometer-bout (MVPA-AB). Data were analyzed using logistic regression to determine the odds ratio (ORs) for low HRQoL, adjusting for socioeconomic variables and mental health factors.
Participants with higher HRQoL were younger, more likely to be male, single, highly educated, employed in white-collar jobs, and had higher household incomes. They also reported less stress and better subjective health status. The high HRQoL group had significantly more participants meeting MVPA-AB ≥600 metabolic equivalents (P<.01). Logistic regression showed that participants meeting MVPA-AB ≥600 metabolic equivalents had higher odds of high HRQoL (OR 1.55, 95% CI 1.11-2.17). Adjusted models showed consistent results, although the association weakened when adjusting for mental health factors (OR 1.45, 95% CI 1.01-2.09).
The study demonstrates a significant association between HRQoL and moderate to vigorous physical activity sustained for at least 10 minutes, as measured by accelerometer. These findings support promoting physical activity, particularly sustained moderate to vigorous activity, to enhance HRQoL. Further interventional studies focusing on specific physical activity domains such as occupational, leisure-time, and commuting activities are warranted.
健康相关生活质量（HRQoL）反映了个体随时间推移对身心健康的感知。尽管有大量研究将身体活动与改善 HRQoL 联系起来，但大多数研究依赖于自我报告的数据，这限制了研究结果的准确性和普遍性。本研究利用客观加速度计数据探讨了韩国成年人中身体活动与 HRQoL 之间的关系。
本研究旨在分析使用加速度计客观测量的身体活动与韩国成年人 HRQoL 之间的关系，旨在通过身体活动为提高 HRQoL 提供针对性的干预措施。
这项观察性研究包括来自韩国国家健康和营养检查调查（KNHANES） VI 的 1298 名 19-64 岁的参与者，他们连续 7 天佩戴加速度计。使用 EQ-5D 问卷评估 HRQoL，身体活动用中等到剧烈体力活动加速度计总（MVPA-AT）和加速度计爆发（MVPA-AB）进行量化。使用逻辑回归分析数据，以确定低 HRQoL 的优势比（ORs），调整社会经济变量和心理健康因素。
HRQoL 较高的参与者更年轻，更有可能是男性、单身、受过高等教育、从事白领工作和家庭收入较高。他们报告的压力较小，主观健康状况较好。高 HRQoL 组中满足 MVPA-AB≥600 代谢当量的参与者明显更多（P<.01）。逻辑回归显示，满足 MVPA-AB≥600 代谢当量的参与者具有更高的高 HRQoL 优势（OR 1.55，95%CI 1.11-2.17）。调整后的模型显示出一致的结果，尽管在调整心理健康因素后，关联减弱（OR 1.45，95%CI 1.01-2.09）。
该研究表明，HRQoL 与使用加速度计测量的至少 10 分钟持续的中等到剧烈体力活动之间存在显著关联。这些发现支持促进身体活动，特别是持续的中等到剧烈活动，以提高 HRQoL。需要进一步开展针对特定身体活动领域（如职业、休闲时间和通勤活动）的干预性研究。
