“…The modest correlation we found between CRF and SPA leisure time (0.351, P < 0.001) may indicate that the activity captured with self‐report could be too broad. The correlations we observed concurs with findings in previous studies 16, 44 and support the assumption that difficulties of obtaining reliable data on physical activity may influence the relationship with cancer.…”

Measured cardiorespiratory fitness and self‐reported physical activity: associations with cancer risk and death in a long‐term prospective cohort study

Physical activity is inversely associated with risk of some cancers. The relation with cancer‐specific death remains uncertain. Mainly, studies on relationships between physical activity and cancer are based on self‐reported physical activity (SPA). Hereby, we examined whether measured cardiorespiratory fitness (CRF) is associated with cancer risk, mortality, and case fatality. We also describe relationships between SPA and these outcomes, and between CRF and SPA. A cohort of 1997 healthy Norwegian men, aged 40–59 years at inclusion in 1972–75, was followed throughout 2012. At baseline, CRF was objectively measured. SPA (leisure time and occupational) was obtained through a questionnaire. Relationships between CRF or SPA, and the outcomes were estimated using Cox regression, adjusted for age, body mass index (BMI), and smoking. Pearson correlation coefficients evaluated agreements between CRF and SPA. During follow‐up, 758 men were diagnosed with cancer and 433 cancer deaths occurred. Analyses revealed lower cancer risk (Hazard ratio [HR] 0.85, 95% confidence intervals [CI]: 0.68–1.00), mortality (HR 0.68, 95% CI: 0.53–0.88), and case fatality (HR 0.74, 95% CI: 0.57–0.96), in men with high CRF compared to low CRF. Light leisure time SPA was associated with lower cancer risk (HR 0.70, 95% CI: 0.56–0.86) and mortality (HR 0.64 95% CI: 0.49–0.83), whereas strenuous occupational SPA was associated with higher risks (HR 1.42, 95% CI: 1.13–1.78 and HR 1.45, 95% CI: 1.09–1.93). Correlations between CRF and SPA were 0.351 (P < 0.001) and −0.106 (P < 0.001) for leisure time and occupational SPA, respectively. A high midlife CRF may be beneficial for cancer risk, cancer mortality, and case fatality.

“…As observed in other studies (22,32), the relative and/or absolute agreement between self-reported and accelerometrybased PA and SB variables were age, sex, education, and weight status specific. This may be due to differences in fitness level, ability to understand the questionnaire items, adequacy of the accelerometry cut points used in this study, habitual patterns of PA and time use, and other factors.…”

. Purpose: Understanding factors that influence accurate assessment of physical activity (PA) and sedentary behavior (SB) is important to measurement development, epidemiologic studies, and interventions. This study examined agreement between self-reported (International Physical Activity Questionnaire-Long Form [IPAQ-LF]) and accelerometry-based estimates of PA and SB across six countries and identified correlates of between-method agreement. Methods: Self-report and objective (accelerometry-based) PA and SB data were collected in 2002-2011 from 3865 adult participants in eight cities from six countries (Belgium, Czech Republic, Denmark, Spain, United Kingdom, and United States). Between-method relative agreement (correlation) and absolute disagreement (mean difference between conceptually and intensity-matched IPAQ-LF and accelerometry-based PA and SB variables) were estimated. Also, sociodemographic characteristics and PA patterns were examined as correlates of betweenmethod agreement. Results: Observed relative agreement (relationships of IPAQ-LF with accelerometry-based PA and SB variables) was small to moderate (r = 0.05-0.37) and was moderated by sociodemographic (age, sex, weight status, and education) and behavioral (PAtype) factors. The absolute disagreement was large, with participants self-reporting higher PA intensity and total time in moderate-tovigorous-intensity PA than accelerometry. Also, self-reported sitting time was lower than accelerometry-based sedentary behavior. After adjusting for sociodemographic and behavioral factors, the absolute disagreement between pairs of IPAQ-LF and accelerometry-based PA variables remained significantly different across cities/countries. Conclusions: Present findings suggest systematic cultural and/or linguistic and sociodemographic differences in absolute agreement between the IPAQ-LF and the accelerometry-based PA and SB variables. These results have implications for the interpretation of international PA and SB data and correlate/determinant studies. They call for further efforts to improve such measures. Key Words: INTERNATIONAL PHYSICAL ACTIVITY QUESTIONNAIRE, LONG FORM, INTERNA-TIONAL, SOCIODEMOGRAPHIC FACTORS, MEASUREMENT, EXERCISE, SEDENTARY TIME P revalence data for physical activity (PA) and sedentary behavior (SB) are now available for dozens of countries based on self-report surveys (1,2,18). The validity and the between-country comparability of these data rely on survey items having the same meaning across cultures and languages and capturing relevant behaviors that are prevalent in specific populations (24). The International Physical Activity Questionnaire (IPAQ) was developed for international use and has evidence of reliability and validity (9). Although the IPAQ-Short Form has been most often used for international prevalence studies (1,2), the IPAQ-Long Form (IPAQ-LF) has also been used in international research, especially in research focused on domain-specific PA and studies of the environmental correlates of PA and SB (6,9). The main diff...
