This study was conducted to criterion-validate the short format of International Physical Activity Questionnaire (IPAQ) against health-related fitness.
Participants included 951 men, aged 21-43 yr. VO2max by ergometer was used to measure cardiorespiratory fitness. Muscular fitness tests included the number of sit-ups, push-ups, and squats performed during 60 s. Physical activity was assessed from IPAQ by categories for health (health-enhancing physical activity (HEPA)) and by calculating total and vigorous MET-hours per week. The participants were classified in five groups of almost equal size by the IPAQ outcomes. Moreover, the frequency of vigorous activity was assessed by one precoded question (single-item question on leisure-time vigorous physical activity (SIVAQ)).
The mean fitness improved from the first through the fourth IPAQ group. VO2max in the most active IPAQ group, however, was lower than in the fourth group (P < 0.05), both with HEPA categories and vigorous METs as the outcome. In contrast, the weekly frequency of vigorous physical activity showed a positive association with fitness through all six categories. The 65 sedentary (according to SIVAQ) and unfit individuals who belonged to the highest 20% (by IPAQ total METs) were older (30.6 +/- 5.1 vs 28.9 +/- 3.8, P = 0.02), more obese (waist 93 +/- 12 vs 89 +/- 10 cm), more often current smokers (59.4 vs 42.0%; P = 0.03), and less educated (<12 yr of education 70.8 vs 52.0%; P = 0.02), compared with the others in the highest IPAQ group.
Almost 10% of young men had poor fitness and apparently low physical activity, but they reported very high physical activity by IPAQ. An evident need therefore exists to develop IPAQ further to solve the apparent overreporting by a considerable proportion of sedentary individuals.
本研究旨在对国际体力活动问卷简版（IPAQ）与健康相关体能进行标准效度验证。
研究对象包括951名年龄在21至43岁之间的男性。通过测力计测量最大摄氧量（VO₂max）来评估心肺功能。肌肉力量测试包括60秒内完成的仰卧起坐、俯卧撑和深蹲的次数。通过IPAQ按健康类别（增进健康的体力活动（HEPA））以及计算每周总的和剧烈的代谢当量小时数来评估体力活动。根据IPAQ结果将参与者分为五组，每组人数大致相等。此外，通过一个预编码问题（关于休闲时间剧烈体力活动的单项问题（SIVAQ））评估剧烈活动的频率。
从第一组到第四组，平均体能有所改善。然而，在最活跃的IPAQ组中，无论以HEPA类别还是剧烈代谢当量为结果，其VO₂max均低于第四组（P<0.05）。相比之下，通过所有六个类别，每周剧烈体力活动的频率与体能呈正相关。在最高的20%（按IPAQ总代谢当量）中，65名久坐不动（根据SIVAQ）且体能不佳的个体年龄更大（30.6±5.1岁对28.9±3.8岁，P = 0.02），更肥胖（腰围93±12厘米对89±10厘米），当前吸烟者更多（59.4%对42.0%；P = 0.03），受教育程度更低（<12年教育70.8%对52.0%；P = 0.02），与最高IPAQ组中的其他个体相比。
近10%的年轻男性体能较差且体力活动明显较少，但他们通过IPAQ报告的体力活动却非常高。因此，显然有必要进一步改进IPAQ，以解决相当一部分久坐个体明显的过度报告问题。
