q3 · i? · associational · r2

Moderation analysis within the same cross-sectional study of 2,812 older adults, testing interactions between obesity and cognitive reserve proxies (education, engagement in activities). The study reports that "obesity was related to lower processing speed and cognitive flexibility only in individuals with low engagement in activities and low education."

"Moderation analyses showed that obesity was related to lower processing speed and cognitive flexibility only in individuals with low engagement in activities and low education."

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 is not related to verbal abilities, processing speed, or cognitive flexibility when cognitive reserve in early and midlife is accounted for — related
• Obesity (BMI ≥30) is associated with lower performance in verbal abilities, processing speed, and cognitive flexibility in older adults — related
• High performance in old age is associated with higher education, foreign language use and IQ, but not physical activity or personality — related
• SES moderates the brain-behavior relationship in children's arithmetic, with higher and lower SES children engaging different neurocognitive systems — a narrower finding that bears on this claim
