Abstract
目的：本研究旨在以主、客觀方式探討不同體型大學女生在身體活動量與活動類型之差異，並考驗主客觀身體活動測量法之相關。方法：本研究招募26位大學女生，依身體質量指數 (body mass index, BMI) 分成13位標準組 (18.5≦BMI< 24) 及13位過重組 (BMI ≧ 24)，採用智慧能量消耗和日常生活活動紀錄器 (Intelligent Device for Energy Expenditure and Activity, IDEEA) 監測平日與假日之身體活動量，並在隔日以三日身體活動回憶量表記錄前一日之身體活動。以獨立樣本t-test考驗兩組受試者在主客觀身體活動量、活動類型與坐式行為之差異，並以皮爾遜積差相關法考驗主客觀身體活動測量法之相關。結果：標準組於主觀問卷之平日與總身體活動量顯著高於過重組(p < .05)，而在客觀身體活動量部分，標準組在平日、假日和總身體活動量皆顯著高於過重組 (p < .05)；兩組於平日上下樓梯之活動類型比例達顯著差異 (p < .05)，包含坐、躺、倚靠三種活動類型之坐式行為並無顯著差異 (p > .05)，且兩組在坐式行為之百分比均佔80 % 以上；標準組和過重組之主、客觀身體活動測量法均呈正相關 (p < .05)，過重組在主、客觀身體活動量間達顯著差異 (p < .05)，不論平、假日在主觀問卷部分皆有高估身體活動量之情形。結論：體型標準大學女生在身體活動量與平日上下樓梯之活動類型比例皆顯著高於過重組。
Purpose: The purposes of this study were to compare the differences of physical activity and activity types in college female students with different body types using objective and subjective measures, and to investigate the associations between objective and subjective measures of physical activity. Methods: Twenty-six college female students were recruited to be assigned into the normal group (NG, n = 13) (18.5 ≦ BMI< 24) and overweight group (OG, n = 13) (BMI ≧ 24). The physical activity (PA) and activity types (AT) for the entire either 1 ordinary day or 1 holiday of each participant were measured by Intelligent Device for Energy Expenditure and Activity (IDEEA) as the objective measure. Next day following the above measure of any day, participants completed the 3-day physical activity recall (PAR) as the subjective measure. The differences of all parameters from either objective or subjective measures between two groups were investigated by independent sample t-test. Besides, the correlation between the objective and subjective measures was assessed using Pearson’s product-moment Correlation. Result: Significantly higher total and ordinary-day PA from subjective measure were noted in the NG comparing to OG (p< .05). Ordinary-day, holiday and total PA from objective measure were significantly higher in the NG than OG (p < .05). Significantly difference was noted in the activity of climbing stairs at ordinary day between two groups (p < .05). No difference between groups was found in sedentary behavior which was more than 80 %. Positive correlation between objective and subjective PA measures was noted in both groups (p < .05). Significant difference of PA between subjective and objective measures was found in the OG. Lastly, overestimated PA was noted at either ordinary day or holiday with subjective PAR. Conclusion: These results indicate that the normal group had higher physical activity and up/down stairs activity type than the overweight group, and body-type is related to physical activity level.
