Adherence
A validated physical activity questionnaire (Kriska questionnaire) significantly correlates with objective energy expenditure (TEE/BMR) in Pima Indians, indicating that self-reported leisure and occupational activity is a reliable proxy for metabolic cost in this population.
For populations with high obesity and diabetes risk, self-reported physical activity questionnaires can be a valid tool to estimate energy expenditure. This allows for better assessment of lifestyle factors without requiring expensive doubly-labeled water tests in large-scale studies.
The activity questionnaire of Kriska... produced highly significant correlations with measurements of energy expenditure... representing an important tool for examining the relationship between activity and disease in population studies.
Why this rating
Small sample size (N=21) and specific demographic limit generalizability, but the correlation with DLW is strong.
