Plasma trace elements and cognitive function in older men and women: The Rancho Bernardo Study

Plasma trace elements and cognitive function in older men and women: The Rancho Bernardo Study

Objective. This study examines the sex-specific associations of plasma concentrations of iron, copper, and zinc with cognitive function in older community-dwelling adults. Design: Cross-sectional study. Setting: 1988-92 follow-up clinic visit. Participants: 602 men and 849 women (average age=75 ?8 y...

Zusammenfassung:Objective. This study examines the sex-specific associations of plasma concentrations of iron, copper, and zinc with cognitive function in older community-dwelling adults. Design: Cross-sectional study. Setting: 1988-92 follow-up clinic visit. Participants: 602 men and 849 women (average age=75 ?8 years) who were community-dwelling and not clinically demented. Measurements: Blood samples were assayed for trace elements and 12 cognitive function tests were administered. Sex-specific analyses were adjusted for age, education, alcohol consumption, smoking, exercise, and estrogen use in women. Results. Men and women differed significantly in education and alcohol intake (p?s
