| 目的 研究国际体力活动问卷(自填式长卷)中文版(IPAQ-C)在成都市12～44岁女性人群中应用的信度和效度.方法 采用整群抽样方式,按照被调查人群年龄分布选取成都市1个社区、1所大学、2所中学(高中和初中).参加者分别于第1、8、28天填写3次IPAQ-C,进行信度研究.参加效度研究者于第一次和第二次问卷填写之间每日填写Bouehard体力活动日记(PA),连续7 d,作为IPAQ-C的效度标准,与第二次IPAQ-C问卷结果进行比较.根据数据分布情况,计算Pearson相关系数或Spearman'相关系数,信度测定计算组内相关系数(ICC).结果 (1)参加信度研究者186人,全部完成第一次问卷填写,完成第二次和第三次问卷填写者分别143人(76.88%)、172人(92.50%).参加效度研究者158人,合格效度问卷143人(90.59%).(2)IPAQ-C信度:1周后重测信度的ICC为0.757～0.972(χ=0.870),1周后的重测信度高于3周和4周后的重测信度[ICC分别为:3周0.472～0.948(χ=0.721),4周0.473～0.925(χ=0.696)],3周和4周后的重测信度相似,重体力活动和闲暇时体力活动的组内相关系数最高(1周后分别为0.966、0.972).(3)IPAQ-C效度:IPAQ-C和PA日记相比,不同强度体力活动能量消耗、总体力活动能量消耗及静坐时间的相关系数为:r=0.445～0.696,重体力活动的相关系数最高(0.696).结论 IPAQ-C信度、效度较好,适合在成都市12～44岁女性人群中使用. |

| Objective To test the reliability and validity of International Physical Activity Questionnaires (long self-administrated format)( IPAQ), Chinese version on women of 12-44 years old, in Chengdu city. Methods Clustered sampling was used, according to the age distribution of investigated population. One community, one university and two middle schools (including one high school and one junior high school) in Chengdu were selected. The reliability study was conducted in a 28-day period.Participants were contacted three times within 28 days (on the 1st, the 8th and the 28th day respectively).In the validity study, participants completed the same questionnaire and Bouchard physical activity diary(PA diary) each day for seven days between visit 1 and visit 2 before comparing the IPAQ's result with Bouchard physical activity diary's for validity study. Pearson or Spearman' correlation coefficients were calculated for validity and interclass correlation coefficients for reliability according to date distribution.Results (1)One hundred and eighty six participants were recruited for the reliability study. All of them completed the first questionnaire with 143(76.88%) and 172 (92.50%) finished the second and third questionnaires. One hundred and fifty eight participants were recruited in the validity study. Qualified questionnaire accounted for 90.59 % (143). (2) Results from the test-retest reliability of the Chinese version of long self-administrated format (IPAQ) showed: the ICC after one week ranged from 0.7373 to 0.972(mean:0.870) which were higher than those interval's reliability [ ICC= 0.472-0.948 for three weeks interval (mean:0.721), and 0.473-0.925 for four weeks interval (mean:0.696)]. The ICCs of three weeks interval and four weeks interval were not significantly different. ICCs for vigorous physical activity and leisure time physical activity were the best. (3)The validity for different intensity, total physical activity and sitting time showed the correlation coefficients between IPAQ and PA diary ranged from 0.445 to 0.696, with correlation for vigorous physical activity the best (r=0.696). Conclusion IPAQ-C seemed a reliable and validated measure of physical activity for 12-44 year-old women in Chengdu city. |
