阿拉伯青少年生活方式研究是一个多中心项目，旨在评估阿拉伯青少年的生活习惯。这项研究报告了ATLS中使用的体力活动问卷相对于电子计步器的收敛效度。研究对象为随机抽取的中学男生39人，女生36人，平均年龄16.1±1.1岁。ATLS自我报告问卷连续三个工作日对照电子计步器进行验证。平均步数为6866±3854步/天，性别差异不显著。问卷调查结果显示，在总强度或中等强度活动上花费的时间没有显著的性别差异。然而，男性在剧烈运动上花费的时间明显多于女性。步数与问卷在所有活动上花费的总时间的相关性为0.369。步数与大强度(r=0.338)的关系大于与中等强度(r=0.265)的关系。计步器步数与步行(r=0.350)和慢跑(r=0.383)时间的相关性高于与其他活动时间的相关性。根据计步器评估，积极的参与者也是问卷调查中最活跃的。看来ATLS问卷是评估阿拉伯青少年习惯性体育活动的有效工具。
The Arab Teens Lifestyle Study (ATLS) is a multicenter project for assessing the lifestyle habits of Arab adolescents. This study reports on the convergent validity of the physical activity questionnaire used in ATLS against an electronic pedometer. Participants were 39 males and 36 females randomly selected from secondary schools, with a mean age of 16.1 ± 1.1 years. ATLS self-reported questionnaire was validated against the electronic pedometer for three consecutive weekdays. Mean steps counts were 6,866 ± 3,854 steps/day with no significant gender difference observed. Questionnaire results showed no significant gender differences in time spent on total or moderate-intensity activities. However, males spent significantly more time than females on vigorous-intensity activity. The correlation of steps counts with total time spent on all activities by the questionnaire was 0.369. Relationship of steps counts was higher with vigorous-intensity (r = 0.338) than with moderate-intensity activity (r = 0.265). Pedometer steps counts showed higher correlations with time spent on walking (r = 0.350) and jogging (r = 0.383) than with the time spent on other activities. Active participants, based on pedometer assessment, were also most active by the questionnaire. It appears that ATLS questionnaire is a valid instrument for assessing habitual physical activity among Arab adolescents.
