Description
Background Many available physical activity questionnaires (PAQs) are limited due to either focus on recreational activities or burdensome length. Aims We sought to assess the reliability and validity of a new short PAQ that captures all activity types. Methods The 12-item multiple-choice PAQ-M included eight activity domains, providing a total Physical Activity Score (PAS-M) in kcal/kg/week. The new PAQ-M was administered with the previously validated Paffenbarger PAQ to 426 men, ages 50–79, undergoing colon-cancer screening. Results The PAQ-M had excellent test–retest reliability (intraclass correlation = 0.87). The PAS-M was moderately correlated with the Paffenbarger Physical Activity Score (PAS-P) (r = 0.31) and inversely correlated with BMI (r = -0.14) and waist circumference (r = -0.17). Adenoma prevalence was inversely associated with the PAS-M (3rd vs. 1st tertile adjusted odds ratio, 0.46; 95% confidence interval, 0.26–0.84) but not with the PAS-P. Conclusions Our new short physical activity questionnaire has excellent test–retest reliability, and was correlated moderately with a widely used physical activity questionnaire and obesity measures. Furthermore, the new PAQ was a better predictor of adenoma prevalence in the expected direction than the Paffenbarger questionnaire in this largely sedentary population
