Notes: PPI = proton pump inhibitor; CI = confidence interval; BMI = body mass index; CES-D = Center for Epidemiological Studies Depression; H2RA = histamine type-2 receptor antagonist; NSAID = nonsteroidal anti-inflammatory drug.
*Interaction: baseline PPI use and baseline age.
†Model 1: Univariate (n = 1 290).
‡Model 2: Adjusted for age (continuous), sex/estrogen status (categorical: male; female premenopausal or postmenopausal with estrogen use and female postmenopausal with no estrogen use), smoking (categorical: nonsmoker/lifetime use of <100 cigarettes, past smoker, and current smoker), education (categorical: education <eighth grade and eighth grade and above), Apolipoprotein E Ɛ4 (categorical: no copies, at least 1 copy, and missing), alcohol frequency (categorical: nondrinker/none within past year, moderate drinker, or heavy drinker), and BMI (categorical: overweight, obese, and extremely obese).
§Model 3: Adjusted for model 2+ depression score (CES-D; continuous), diabetes (categorical: yes/no), hypertension (yes/no), and stroke (yes/no).
‖Model 4: Adjusted for model 3+ anemia (yes/no), H2RA (yes/no), platelet aggregation inhibitors (yes/no), aspirin (yes/no), NSAID (yes/no), multivitamin (yes/no), and Mediterranean diet score (range 0–9).
