Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? Obesity (BMI ≥30) was significantly associated with lower performance in verbal abilities, processing speed, and cognitive flexibility in a large sample of older adults. → Ihle 2016

q3 · i? · associational · r2
Cross-sectional analysis of 2,812 older adults using psychometric tests of verbal abilities, processing speed, and cognitive flexibility, with BMI from self-reported weight and height. The study reports that "Obesity (BMI ≥30) was significantly associated with a lower performance in verbal abilities, processing speed, and cognitive flexibility."
"Obesity (BMI ≥30) was significantly associated with a lower performance in verbal abilities, processing speed, and cognitive flexibility."
Discussion¶
Learner Variables¶
- Executive Function — predictor: learners who differ on it differ in outcomes
- Physical Well-Being — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Obesity relates to lower processing speed and cognitive flexibility only among older adults with low education or low engagement in activities — related
- Obesity is not related to verbal abilities, processing speed, or cognitive flexibility when cognitive reserve in early and midlife is accounted for — reports the opposite
