Health-related quality of life (HRQoL) has been characterized as the ultimate goal for health interventions such as physical activity (PA). We assessed how frequency, duration, and intensity of PA were related to HRQoL in younger (<65 yr) and older (≥65 yr) females and males.
This population-based cross-sectional study explored associations between frequency, duration, and intensity of PA and physical and mental health. HRQoL was measured by SF-8 Health Survey. Frequency and duration were assessed by items validated in a previous HUNT study, and intensity was assessed by Borg RPE scale. Associations between PA and physical and mental health were estimated using general linear modeling.
A total of 4500 participants (56% females), age 19-91 yr, with mean age of 53±15 yr, were included. Of these, 40% were less active than recommended by international guidelines. In general, mean physical health (PCS-8) in females and males was 47.4±9.7 and 48.8±8.9, and mental health (MCS-8) was 50.5±8.0 and 51.9±7.3, respectively. Age-adjusted association between PA and HRQoL was stronger for physical than mental health in both genders and age groups. The largest differences were between no exercise and exercise groups at any level for frequency, duration, and intensity of PA. We found no substantial gender differences in association between PA and HRQoL, but association was stronger in older (≥65 yr) than younger (<65 yr) females and males. Adjusting for socioeconomic factors and factors such as presence of diseases, body mass index, smoking habits, cohabitation, and disablement did not change the results.
The study suggests that exercising at any level is associated with better physical and mental health in both genders compared with no exercise, particularly among the older individuals.
健康相关生活质量（HRQoL）已被认为是体育活动（PA）等健康干预的最终目标。我们评估了 PA 的频率、持续时间和强度与年轻（<65 岁）和老年（≥65 岁）女性和男性的 HRQoL 之间的关系。
这项基于人群的横断面研究探讨了 PA 的频率、持续时间和强度与身心健康之间的关联。HRQoL 通过 SF-8 健康调查进行测量。频率和持续时间通过之前 HUNT 研究中验证的项目进行评估，强度通过 Borg RPE 量表进行评估。使用一般线性模型估计 PA 与身心健康之间的关联。
共有 4500 名参与者（56%为女性），年龄 19-91 岁，平均年龄为 53±15 岁，其中 40%的人活动量低于国际指南推荐的水平。一般来说，女性和男性的生理健康（PCS-8）平均为 47.4±9.7 和 48.8±8.9，心理健康（MCS-8）平均为 50.5±8.0 和 51.9±7.3。在所有性别和年龄组中，PA 与 HRQoL 的年龄调整关联在生理健康方面强于心理健康。PA 的频率、持续时间和强度方面，最大的差异存在于任何运动水平的无运动组和运动组之间。我们没有发现 PA 与 HRQoL 之间存在实质性的性别差异，但在老年（≥65 岁）女性和男性中，这种关联比年轻（<65 岁）女性和男性更强。调整社会经济因素以及存在疾病、体重指数、吸烟习惯、同居和残疾等因素并不会改变结果。
该研究表明，与不运动相比，任何水平的运动都与两性的生理和心理健康状况更好相关，尤其是在老年人中。
