高科技男性工程師身體活動測量工具效度探討

Validating Physical Activity Assessment Tools for Measuring Physical Activity in High-technology Male Engineers

近幾年台灣以高科技產業品揚名國際，使得高科技產業員工獲得優渥薪資及獎金，但是在這高薪資背後必須接受長時間工作與技術快速改變的工作壓力；根據新竹科學園區員工診所統計，30歲以上之高科技從業人員身體健檢查資料分析結果，近四成高科技從業人員有心血管危險因子（體重、總膽固醇和血壓異於正常值），其中男性從業人員狀況比女性嚴重。因此，本研究嘗試探討台灣國際身體活動量表（IPAQ）自填長版與修正式台灣體能活動量表（MOSPA）之效度，並以加速度計Actical作為效標，對高科技男性工程師身體活動測量的適用性，有助於給予增加身體活動之建議，促進身體健康。經過研究分析發現：修正式MOSPA身體活動量表與Actical達低度相關（r=0.46）；而IPAQ身體活動量表與Actical未具顯著關係。修正式MOSPA身體活動量表效標關聯效度雖不高，但其操作簡單，可收集高科技男性工程師長期身體活動能量消耗情況，且符合經濟效益，適合大規模測量使用。

In the past few years, Taiwan's information technology industry made famous in the worldwide high-tech market, which allowed high-tech employees acquired high wages and benefits. However, behind this abounded income compensation, most IT employees have to face long work time and high work stress in order to catch up with the rapid change of information technology. According to a health survey done by CLINIC OF HSINCHU SCIENCE PARK, At age 30 years and over the prevalence of cardiovascular risk factors (weight, total cholesterol and blood pressure higher than normal value) in high-tech employees was near 40%, in which male employees have more adverse profile than female employees. Therefore, this study aims at validating two physical activity questionnaires, naming Taiwan International Physical Activity Questionnaire (IPAQ) long version and the modified WHO-MONICA Optional Study of Physical Activity Questionnaire (MOSPA) for measuring physical activity levels in male engineers to promote health. The results showed that modified MOSPA held a significant correlation with the criterion in total physical activity EE (r = 0.46 respectively), whereas IPAQ held no statistical significance. The MOSPA questionnaire is easy to administer and moderately correlated to accelerometer data, is suitable for assessing physical activity levels in high-technology male engineers in large scale field studies.
