Association of body mass index, waist circumference, (abdominal) overweight and obesity with sex- and age-specific cognitive function over time—the Doetinchem Cohort Study

Key Points

• This research investigates how body mass index and waist circumference relate to cognitive function across different ages and sexes.
• Analyzed longitudinal data from the Doetinchem Cohort Study.
• Examined associations between BMI, waist circumference, and cognitive performance.
• Considered sex-specific and age-related effects.
• Higher BMI and waist circumference are associated with poorer cognitive function in both sexes.
• Waist circumference showed a stronger link with cognition than BMI.
• Only men exhibited significant cognitive decline related to these measurements.
