Precise measurements of activity at a population level are important for monitoring trends and evaluating health promotion strategies. Few studies have assessed the measurement of physical activity in developing countries. The aim of this study was to validate the MOSPA (Monica Optional Study of Physical Activity) questionnaire which was developed for the WHO-Monitoring trends and determinants of cardiovasculr disease (MONICA) study sites.
The MOSPA questionnaire assesses energy expendtiture (EE) related to physical activity (employment, household work, transportation, and leisure time) over a one year period. This questionnaire has been described in the manuscript as the long term (LT) questionnaire. An adapted short term (ST) 5 day questionnaire was developed to assess convergent validity. Questionnaire data were compared with physical activity EE estimates from a Caltrac accelerometer and with body composition measures (height, weight and bioelectrical impedance) in 50 women from the Aga Khan University (AKU) hospital antenatal clinics, Pakistan. Other forms of EE i.e. resting EE and thermic effect of food were not assessd in this study.
Subjects were aged 26 +/- 3.8 years and were 16.1 +/- 6.7 weeks pregnant. Their average weight was 58.8 +/- 10.7 Kg. The average EE/day assessed by the Caltrac accelerometer, was 224 kcal and by MOSPA LT questionnaire it was 404 kcal. The questionnaires and Caltrac data were reasonably well correlated: r = 0.51 and r = 0.60 (P < 0.01) for LT and ST questionnaires respectively. Energy expenditure from questionnaire data was not correlated with body composition measures.
The MOSPA questionnaire is useful in assessing physical activity levels in a sedentary population over a one year period.
在人群层面精确测量活动量对于监测趋势和评估健康促进策略至关重要。很少有研究评估发展中国家身体活动的测量情况。本研究的目的是验证为世界卫生组织心血管疾病监测趋势和决定因素（MONICA）研究地点开发的MOSPA（莫妮卡身体活动可选研究）问卷。
MOSPA问卷评估一年内与身体活动（就业、家务劳动、交通和休闲时间）相关的能量消耗（EE）。该问卷在稿件中被描述为长期（LT）问卷。开发了一种经过改编的短期（ST）5天问卷以评估收敛效度。在巴基斯坦阿迦汗大学（AKU）医院产前诊所的50名女性中，将问卷数据与来自Caltrac加速度计的身体活动EE估计值以及身体成分测量值（身高、体重和生物电阻抗）进行了比较。本研究未评估其他形式的EE，即静息EE和食物的热效应。
受试者年龄为26±3.8岁，怀孕16.1±6.7周。她们的平均体重为58.8±10.7千克。通过Caltrac加速度计评估的平均每日EE为224千卡，通过MOSPA LT问卷评估为404千卡。问卷和Caltrac数据具有合理的良好相关性：LT和ST问卷的r分别为0.51和0.60（P<0.01）。问卷数据中的能量消耗与身体成分测量值无关。
MOSPA问卷可用于评估久坐人群一年内的身体活动水平。
