Abstract

Reproducibility and validity of the physical activity questionnaire (PAQ) used in the Shanghai Men's Health Study (2003-2006, People's Republic of China) was evaluated in a random sample of 196 participants aged 40-74 years. Participants completed a PAQ at baseline and again 1 year later, 12 monthly 7-day physical activity recalls, and four quarterly 1-week physical activity logs. Reproducibility was evaluated by using the two PAQs and validity by comparing the PAQs with 1-year averages of the two criterion measures: 7-day physical activity recall and physical activity log. The PAQ had moderate to high reproducibility for measuring adult exercise participation (κ = 0.60) and energy expenditure (rs = 0.68), nonexercise activities (correlation coefficients = 0.42-0.68), and total daily energy expenditure (rs = 0.68, κquartiles = 0.47). Correlations between the PAQ and criterion measures of adult exercise were 0.45 (7-day physical activity recall) and 0.51 (physical activity log) for the first PAQ and 0.62 (7-day physical activity recall) and 0.71 (physical activity log) for the second PAQ. Correlations between PAQ nonexercise activities and the physical activity log and 7-day physical activity recall were 0.31-0.86. Correlations for total energy expenditure were high (0.62-0.77). Results indicate that the Shanghai Men's Health Study PAQ has reasonable reproducibility and validity for classifying men by their level of exercise and nonexercise activities in this cohort.
