| 目的<\b> 评价国际体力活动问卷(IPAQ)中文版的信度和效度,提供体力活动水平测量工具。方法<\b> 系统抽样94名大学生,间隔3天重复调查检验信度;在39名自愿受试者中,用体力活动(PA)记录和Caltrac加速度计为参照标准检验效度。结果<\b> 长短卷各项体力活动组内相关系数均在0.7以上。长卷的体力活动能量消耗与PA记录接近。短卷一日总能量消耗低于PA记录和Cltrac监测值。两个问卷与PA记录的目标体力活动量达标一致率均在70％以上。长卷、短卷和PA记录的每天静坐时间差异无显著性。结论<\b> IPAQ中文版在大学生中的重测信度和效度高于或等于同类问卷。长短卷检测体力活动量达标率与PA记录接近,短卷低估体力活动能量消耗。 |

| Objective<\b> To study the reliability and validity of Chinese version of International Physical Activity Questionnaire (IPAQ) and to provide an instrument for physical activity measurement in Chinese--spoken population. Methods<\b> Test--retest reliability was systemically assessed in 94 participants sampled from college students. Questionnaires were completed twice with a three-day interval. The validity was established in 39 volunteers by Caltrac accelerometer monitoring and 24--hour activity recording for seven consecutive days. Results<\b> Both long vision (LV) and short vision (SV) had intraclass corrlation coeficients above 0. 7 for physical activity. The total energy expenditure measured by LV, SV and PA records were 264. 5±260. 9, 185. 4±128. 9 (compared with activity records, P 0. 05) and 250. 5± 141. 2 MET--min/d respectivaly. Energy expenditure of moderate physical activity were 81. 7±165. 4, 32. 0±42. 5 (compared with activity record, P 0.05) and 61. 3±72. 0 MET--mien/d. Caltrac accelerometer was moderately correlated with LV (r = 0. 50) and SV (r = 0. 63) while SV measured total daily energy expenditure was lower than activity records. When participants were categorized into two groups according to their time spent in physical activity above or below the target level, proportions of agreement of questionnaires and 24-hour activity records were high, including vigorous physical activity above 90 % and moderate physical activity above 70 %. LV, SV and activity records were measured durin sedentary condition at an approximate level. Conclusion<\b>s Both LV and SV of IPAQ appeared to have acceptable reliability and validity, compared to other physical activity instruments that were used in various large epidimiological studies. The total or physical energy expenditures were similar between LV and activity record. For activity levels, the proportion of agreement were similar between activity records and LV or SV. However, SV underestimated the energy expenditure of total and moderate physical activity. |
