Ability of physical activity measurements to assess health-related risks.
The aim of this study is to evaluate if two different physical activity (PA) questionnaires have similar ability to rank individuals, and to examine associations with cardiovascular-metabolic risk factors, compared to an objective measure. In a random sample (n=369, age: 65+/-6 years) from the population-based 'Malmö Diet and Cancer' (MDC) cohort, PA was measured by a leisure-time comprehensive questionnaire (MDC-score), a simple leisure-time questionnaire and by accelerometer-monitoring (CSA). Moderate correlations were observed between MDC-score and CSA in men and women (r=0.35 and 0.24, respectively). In men, both questionnaires and CSA were inversely associated with waist circumference, insulin resistance and metabolic syndrome. In women, the MDC-score was positively associated with high-density lipoprotein-cholesterol, and the simple questionnaire inversely associated with anthropometric indexes, but no association was seen between PA estimates and cardiovascular components. We conclude that both PA questionnaires distinguish health risks associated with anthropometric-metabolic risk factors, particularly in men.
