Physical activity contributes to improve health and reduce mortality in older people. The objective was to analyze the validity of content and reliability of the short version of IPAQ-E in elderly people who attended to Fernando el Católico health center between May 2013 and March 2015.
Validation study of the short version of the international physical activity questionnaire (IPAQ) adapted in Spanish elderly (IPAQ-E). Our sampling was for convenience. The short version of IPAQ in Spanish USA was used and its activities were adapted to Spanish elderly. Two measurements of IPAQ-E with 15 days between them were used to analyze the intraobserver reliability. The intraclass correlation coefficient was used to measure intraobserver reliability, Cronbach's alpha for internal consistency (CI) and Spearman correlation coefficients (CS) to analyze the correlation between IPAQ-E and the Short Physical Performance Battery (SPPB).
The sample was 139 people, average age 73,18 years. Intraobserver reliability total was 0.914, besides exceeded 0.9 in the three dimensions of the questionnaire. The CI was 0.518; It exceeded 0.8 in the rest of dimensions of IPAQ-E. The CS between IPAQ-E Total and SPPB was (Rho 0.435), between the total scores SPPB and walking activity was (Rho 0.426), and the score vigorous activity was (Rho 0,248).
The IPAQ-E is a valid and reliable instrument for measuring mobility in Spanish elderly. However, more studies about its validity will be required in the future.
体育活动有助于改善老年人的健康状况并降低死亡率。本研究旨在分析2013年5月至2015年3月期间在费尔南多·埃尔·卡托利科健康中心就诊的老年人中，国际体力活动问卷简版（IPAQ-E）的内容效度和信度。
对适用于西班牙老年人的国际体力活动问卷简版（IPAQ-E）进行效度研究。我们采用方便抽样。使用了西班牙文版的美国IPAQ简版，并对其活动进行了适用于西班牙老年人的调整。采用两次间隔15天的IPAQ-E测量来分析观察者内信度。组内相关系数用于测量观察者内信度，Cronbach's α用于分析内部一致性（CI），Spearman相关系数（CS）用于分析IPAQ-E与简短身体性能测试（SPPB）之间的相关性。
样本为139人，平均年龄73.18岁。观察者内信度总分是0.914，问卷的三个维度均超过0.9。CI为0.518；在IPAQ-E的其他维度中超过0.8。IPAQ-E总分与SPPB之间的CS为（Rho 0.435），SPPB总分与步行活动之间的CS为（Rho 0.426），剧烈活动得分的CS为（Rho 0.248）。
IPAQ-E是测量西班牙老年人身体活动能力的有效且可靠的工具。然而，未来还需要更多关于其效度的研究。
