The fat‐but‐fit paradigm within the context of cognitive function

摘要: Objective To evaluate the association of Fat-but-Fit paradigm with cognitive function in an older adult population. Methods Data from 1999–2002 National Health and Nutrition Examination Survey were used (N = 2,336 adults 60–85 yrs). Physical activity was assessed via open-ended questions asking about participation 48 leisure-time activities over previous 30 days. Using Metabolic Equivalent Task calculations for each activity, participants classified as either active or inactive. Participants then into one six groups (Normal BMI Inactive [referent], Overweight Inactive, Obese Normal Active, Active), based on their status body mass index (BMI). The Digit Symbol Substitution Test (DSST) employed to assess function. Results Compared those who had a normal inactive (referent), 4-unit higher DSST score (β = 4.0; 95% CI: 1.0–6.9; P = 0.009); overweight 4.5-unit (β = 4.5; 1.3–7.6; P = 0.008); obese 3.7-unit (β = 3.7; 0.96–6.4; P = 0.01). Conclusion Being active, regardless weight classification (normal, overweight, obese) positively associated this sample adults. This suggests that perhaps best strategy promote health population may be encourage adequate levels physical activity.
