研究目的 身體活動是重要的健康行為之一,對成人身、心健康亦有明顯助益。但就過去調查與研究結果均發現,我國成人身體活動量明顯不足,而此結果背後所衍生的相關問題,如肥胖、不佳的體適能、罹患疾病的機會提高,更可能造成個人健康與社會醫療成本的損失。近年來,諸多的研究著重於探討身體活動與生活品質及幸福感間之關係,然心理領域健康相關生活品質與身體活動間之關係尚未確立,且多數研究亦未採用能描述內心平和與和諧狀態的幸福感。若能了解其間之關係,則能更加肯定促進規律運動行為之政策能有效使成人之生活品質與幸福感獲得改善。 研究方法 本研究以378名18-65歲成人為研究對象,採國際身體活動量表、Short Form-36 Health Survey(SF-36)與安適幸福感量表測量成人身體活動量、健康相關生活品質與幸福感。並以結構方程模式進行整體理論模型之徑路分析。 研究結果 本研究結果發現身體活動量、生理領域健康相關生活品質、心理領域健康相關生活品質與安適幸福感間均有顯著正相關。由徑路分析結果可知最佳適配模型中顯示身體活動量可以藉由生理領域健康相關生活品質來提升心理領域健康相關生活品質,且身體活動量亦可藉由健康相關生活品質來提升安適幸福感。 結論 身體活動所具有的沉思與冥想特性,培養個體較不易受正向或負向刺激分心之能力,雖然因而在日常生活中經驗到較少的情緒波動,然而可能僅有內心平和(peacefulness)的感覺,僅有當生理領域與心理領域健康相關生活品質被提升時,個體才能經驗到內在和諧(harmony)與內、外在間達到平衡(balance)的狀態,亦即,身體活動量需透過健康相關生活品質的提升以達到更高層次的幸福感-安適幸福感。
Background and purpose Physical activity is one of the important health behaviors, and is very helpful for physical and mental health of adults. According to past surveys and studies, it was found that the amount of physical activity of adults was under ideal. This might lead to the following related issues, such as obesity, poor physical fitness, and increasing the probability of illness, and thus it will more likely lead to the loss of personal health and increasing social medical costs. In recent years, many studies have focused on investigating the relationship among physical activity, quality of life, and happiness, but the relationship between the psychological field of health-related quality of life and physical activity has not been established. Moreover, most studies did not use the construct of well-being which emphasized peacefulness and harmony in the inner state. If we can understand the above relationship, promoting regular exercise might effectively improve adults' quality of life and happiness. Method The participants in this study were 378 adults (18-65 years old). The instruments used included the International Physical Activity Questionnaire (IPAQ), Short Form-36 Health Survey (SF-36), and Peace of Mind Scale to measure the amount of physical activity, health-related quality of life, and peace of mind respectively. Structural Equation Model (SEM) was used to analyze the data. Results The results of this study showed significant positive correlations among physical activity, physiological field of health-related quality of life, psychological field of health related quality of life, and peace of mind. In path analysis, the best-fit model showed that physical activity improved the psychological field of health-related quality of life via the physiological field of health-related quality of life, and physical activity could also improve peace of mind via health-related quality of life. Discussion As physical activity has meditation characteristics, it can train individuals being less distracted from positive or negative stimuli. Although this may lead to experience fewer mood fluctuations in daily life, it may only lead to the state of peacefulness. Only when both the physiological field and the psychological field of health-related quality of life are raised, individuals can experience harmony and balance in the inner state. That is, physical activity required the mediation of health-related quality of life in order to enhance a higher level of happiness – peace of mind.
